Configure a multicast event
To multicast a live stream, use the Multicast Configurator to configure the streaming event. The Multicast Configurator
generates a Publisher Stream Name that you’ll use to publish a stream from Flash Media Live Encoder. The Multicast
Configurator also generates an F4M (Flash Manifest) file that you’ll use to play the stream in the Multicast Player.
to generate a stream name and a manifest file for the Multicast Player
1 Open the following URL in a web browser:
http://public-dns/multicast/configurator/configurator.html
For example:
http://ec2-174-129-151-131.compute-1.amazonaws.com/multicast/configurator/configurator.html
2 Select Peer to Peer multicast.
Adobe Media Server on Amazon Web Services does not support Fusion or IP Multicast.
3 Enter the server name (or IP address) and the full path to the multicast application:

Securing the server
Modifying a Security Group
When you create an instance, you must create a Security Group or select an existing Security Group. A Security Group
is the Amazon Web Services term for a firewall. Configure the Security Group to allow and deny access to the instance.
When an instance is running, you cannot change the Security Group it belongs to. You can modify the rules of that
Security Group, however.
Amazon says, “A security group defines firewall rules for your instances. These rules specify which incoming network
traffic should be delivered to your instance (e.g., accept web traffic on port 80). All other traffic is ignored. You can
modify rules for a group at any time. The new rules are automatically enforced for all running instances.”
1 In the AWS Management Console, in the Navigation pane, click Security Groups.
2 Select the Security Group to modify. The rules for the Security Group are displayed in the lower pane.
3 To add a rule, provide the following information and click Save:
• Protocol
This menu contains a list of protocols and the ports they most commonly use. For example, HTTP uses port 80.
The RTMP protocol is not included in this list. To add it, select Custom and enter 1935 for the From Port and To
Port.
• From Port
This is the low number in a range. To open a single port, use the same value for the From Port and To Port.
• To Port
This is the high number in a range. To open a single port, use the same value for the From Port and To Port.
• Source (IP or Group).
Last updated 8/28/2014

Using Adobe Media Server on Amazon Web Services
From the Amazon documentation: To allow access from other instances in a security group, enter the security group
name in the Connection Source field.To configure this rule to apply to an IP address range, enter the CIDR range.
For example, enter 0.0.0.0/0 to allow all IP addresses to access the specified port range. Enter an IP address or subnet to
limit access to that one computer or network, for example 92.23.32.51/32.
Add rules to the Security Group
By default, Adobe Media Server is configured to use the following ports and protocols to stream media. Define the
following ports in a Security Group:

Using Adobe Media Server on Amazon Web Services
Managing the server
Remote management tools
To manage your Amazon Web Services account, use any of the following:
• AWS Management Console
When you sign in to the console, select Amazon EC2 from the drop-down list. Or, after you sign in to the console,
select the Amazon EC2 tab. After you sign in, you can launch an instance of Adobe Media Server.
• Elasticfox, a Firefox browser extension that works much like the AWS Management Console.
• Amazon Web Services API
Amazon has several developer tools that let you call the Web Services API to manage your instances and
applications. See Amazon Developer Tools.
• Amazon EC2 API Tools
Amazon describes these tools as, “The client interface to the Amazon EC2 web service. Use these tools to register
and launch instances, manipulate security groups, and more.”
To connect to the Adobe Media Server instance from a remote computer, use any of the following:
• SSH clients (for example, PuTTY, Terminal, and WinSCP). These SSH clients can also use SCP (Secure Copy
Protocol) and SFTP (Secure File Transfer Protocol). See Managing content.
• Adobe Media Server Administration Console
You can use the Administration Console to manage multiple Adobe Media Server instances. Adobe Media Server
Administration Console is not configured to run by default.
Adobe Media Server Administration Console
Adobe Media Server Administration Console is not configured to run by default. To use it, you must enable it in the
ams.ini configuration file and start it.
For general information about the Administration Console, see Using the Administration Console.
Configure the Administration Server
Note: Before running any command in Adobe Media Server Administration Console, add a sudo command before it to
assume super user or root user privileges. This is necessary because root user is disabled in AMS version 5.0.4 and higher
and amsadmin is the new user. amsadmin user has permission to browse the contents of the AMS installation directory.
1 In /opt/adobe/ams/conf/ams.ini, set values for the following parameters:
• SERVER.ADMIN_USERNAME = someusername
• SERVER.ADMINSERVER_HOSTPORT = :1111
The first two parameters add one user for the Administration Console. To add additional users, see the next section,
“Add administrators”.
To set the administrator password, perform the following steps:
1 Ensure that AMSAdmin is not running.
2 Execute the following command from the shell:opt/adobe/ams/amsadmin –console –user someusername
Last updated 8/28/2014

Using Adobe Media Server on Amazon Web Services
You will be prompted to enter a password. Ensure that the password is atleast 8 characters long.
3 Go to Users.xml and check for the salted hash of your password under the password tag.
4 Restart the server:
./amsmgr server ams restart
5 Open port 1111 in the Security Group of the instances you want to administer. Open the port only to the IP
addresses that are allowed to access the Administration Server. See Modifying a Security Group.
Start, stop, or restart the Administration Server
1 Do one of the following to connect to the instance over SSH:
• Connect to an instance and copy files from a Windows computer (To start or stop the Administration Server
connect with PuTTY, not WinSCP. WinSCP is for copying files.)
• Connect to an instance and copy files from a Linux/UNIX computer
2 Enter the following to change to the Adobe Media Server root installation directory:
cd /opt/adobe/ams
3 To start, stop, or restart the server:
./amsmgr adminserver start | stop | restart
Add administrators
1 To add administrators for a particular application, copy a Users.xml configuration file from opt/adobe/ams/conf to
/mnt/applications/myapplication. Add a <User></User> section to the Users.xml file with the username and
password of the administrator.
See Configure an application.
2 You can optionally specify which IP addresses and domains each administrator is allowed to connect from
<Allow></Allow>, and which IP addresses and domains each administrator is not allowed to connect from
<Deny></Deny>.
3 Restart the server and the Administration Server:
./amsmgr adminserver restart
./amsmgr server ams restart
Note: When you edit a configuration file, restart Adobe Media Server. When you edit the Users.xml configuration file,
restart Adobe Media Server and Adobe Media Administration Server.

http://public-dns/ams_adminConsole.htm
For example:
http://ec2-184-72-164-117.compute-1.amazonaws.com/ams_adminConsole.htm
The Administration Console is located on the instance in the following directory:
/mnt/webroot/ams_adminConsole.htm
2 In the Server Address box, enter the Public DNS of the instance.
3 Enter the administrator username and password.
The username and password are stored in the /opt/adobe/ams/conf/ams.ini file.
For security reasons, the administration console does not save your password between sessions.
4 (Optional) Select the Automatically Connect Me option.
5 (Optional) Click Revert to return the Administration Console to its default settings.
Reverting deletes all saved servers, user names, and passwords from the Administration Console. All custom
resizing within the Administration Console is restored to the original state. (The Revert button, however, does not
affect the server.)
6 Click Login.
You can disconnect at any time by clicking Logoff.
Run the Administration Console from another computer
To run the Administration Console from a computer other than the one hosting the instance, copy
ams_adminConsole.htm, ams_adminConsole.swf, and AC_RunActiveContent.js from /opt/adobe/ams/tools to the
other computer.
Verify that the Allow and Deny tags in the Users.xml file allow the connection from the other computer’s IP address.
Using the Administration API
The Adobe Media Administration Server has an API that you can use to monitor and administer the server. You can
call Administration APIs over RTMP and HTTP.
Adobe Media Server 5.0.1 Administration API Reference
To call Administration APIs, configure and start the Administration Server. See the tasks in the section Adobe Media
Server Administration Console . After you’ve completed those tasks, you can call Administration APIs over RTMP.
Call Administration APIs over HTTP:
1 Edit the /opt/adobe/ams/conf/ams.ini file as follows:
USERS.HTTPCOMMAND_ALLOW = TRUE
2 Edit the file opt/adobe/ams/conf/Users.xml to list the Administration APIs that can be called over HTTP (only ping
is allowed, by default):

restart Adobe Media Server and Adobe Media Administration Server.
For more information, see Working with the Administration API.
Starting and stopping an instance
When you launch an instance, the instance is backed by Amazon Secure Simple Storage (S3). After you launch the
instance, you can create an Elastic Block Storage (EBS) volume and attach it to the instance. The major difference
between S3-backed and EBS-backed instances is that EBS-backed instances can be stopped and restarted. Instances that
are S3-backed can be launched and terminated, they cannot be stopped and restarted.
Note: When you terminate an instance, any changes made to that instance (media copied to the instance and changes to
configuration files) are lost. To save media and configuration files, copy them off the instance before you terminate.
Terminate an instance
You cannot stop an instance backed by S3, you must terminate it. To start it, you have to launch a new instance (choose
an AMI, define a security group, and so on).
1 In the AWS Management Console, select the instance.
2 Select the Instance Actions drop-down list and choose Terminate.
Stop an instance
You can stop an instance backed by EBS. You cannot stop an instance backed by S3.
1 In the AWS Management Console, select the instance.
2 Select the Instance Actions drop-down list and choose Stop.
Start an instance
You can start an instance backed by EBS. You cannot start an instance backed by S3.
1 In the AWS Management Console, select the instance.

Installation directories
Adobe Media Server is installed to the following directory:
/opt/adobe/ams
The configuration files are installed to the following directory:
/opt/adobe/ams/conf
Adobe Media Server on Amazon Web Services has a few differences from a standard Adobe Media Server installation.
The following directories are located in the /mnt directory:
/mnt/applications
/mnt/logs
/mnt/webroot
The applications, logs, and webroot directory are in the /mnt directory, because on Adobe Media Server on Amazon
Web Services, the /mnt directory contains more storage space than the / <root> directory.
Logging
The Adobe Media Server log files are written to the following directory:
/mnt/logs
Last updated 8/28/2014

Using Adobe Media Server on Amazon Web Services
For more information about logging, see Monitoring and Managing Log Filesin the Adobe Media Server Configuration
and Administration Guide.
Configuration files
The server configuration files are located in the following directory:
/opt/adobe/ams/conf
You can edit configuration files just as you would on any edition of Adobe Media Server. See Working with
configuration files.
Note: When you terminate an instance, all content on the instance is permanently deleted. Before you terminate an
instance, copy any content you’ve added or modified, including configuration files, off the instance.
The following are the differences between the standard Adobe Media Server Extended configuration files and the
Adobe Media Server on Amazon Web Services configuration files:
• Adaptor.xml
Adaptor/RTMFP/Core/HostPortList/HostPort has a public attribute to allow UDP traffic through Amazon’s
firewall:
<HostPort public="184.72.197.33:19350-19360">:19350-19360</HostPort>
• ams.ini
The Administration Server is not configured or started by default. (See Adobe Media Server Administration
Console .) To connect to the Administration Server, configure a port:
SERVER.ADMINSERVER_HOSTPORT = :1111
On an instance, the /mnt directory is much larger than the /opt directory. Therefore, content is configured to live in
subdirectories of /mnt:
LIVE_DIR = /mnt/applications/live VOD_COMMON_DIR = /mnt/webroot/vod VOD_DIR =
/mnt/applications/vod/media VHOST.APPSDIR = /mnt/applications LOGGER.LOGDIR = /mnt/logs
For information about configuring the server for optimum performance for your streaming use case, see Configuring
performance features in the Adobe Media Server Configuration and Administration Guide.
Apache HTTP Server configuration
The Apache HTTP Server configuration on Adobe Media Server on Amazon Web Services is the same as it is on other
editions of Adobe Media Server. Adobe Media Server listens on port 80 and proxies unknown HTTP requests to port
8134. Apache listens on port 8134.
The Apache root directory is /opt/adobe/ams/Apache2.2/.
The Apache webroot directory is /mnt/webroot/.
For more information, see Configuring Apache HTTP Server.
Managing content
Last updated 8/28/2014

Using Adobe Media Server on Amazon Web Services
About managing content on an instance
When you launch an instance, the instance contains a new installation of Adobe Media Server for Amazon Web
Services. To stream media, use an SSH client to connect to an instance and move the media and any supporting content
(application folders and configuration files) to the instance.
An AMS instance uses two EBS volumes. The first volume is the primary volume that contains the installed operating
system, AMS, and storage blocks. The second volume, which is the secondary volume, is mounted to the /mnt folder
that contains applications, logs, and the webroot folder.
For additional information and screenshots, see Launch an Instance in “Amazon Elastic Compute Cloud Getting
Started Guide”.
Before you terminate an instance, copy all the media and any supporting content, including modified configuration
files, to an Amazon Simple Storage Service (S3) block or to an Amazon Elastic Block Storage (EBS) volume. Any files
left on the instance are deleted when the instance is terminated.
Using Amazon Simple Storage Solution (S3) to store content
Using Amazon Elastic Block Store (EBS) to store and stream content
Note: When you terminate an instance, all content on the instance is permanently deleted. Before you terminate an
instance, copy any content you’ve added or modified, including configuration files, off the instance.
Where to store content on an instance
The Adobe Media Server vod (video on demand) application has a default directory in which it looks for content
(media files) to stream. However, you can configure the server to use any directory. On Adobe Media Server on
Amazon Web Services, store content in any subdirectory of the following directory:
/mnt
On Amazon EC2 instances, the /mnt directory is much larger than the / directory. Therefore, on Adobe Media Server
instances, the /applications, /logs, and /webroot directories are all subdirectories of /mnt.
The following table lists the default content directory and configuration location:
Application
Default content directory
Configuration location
vod
This application plays on-demand streams
from the following directory:
/opt/adobe/ams/conf/ams.ini file
VOD_DIR = /mnt/applications/vod/media
/mnt/applications/vod/media
Flash Player and AIR clients can stream FLV
files in that directory from the following URL:
rtmp://public-dns/vod/filename
Flash Player and AIR clients can stream
F4V/MPEG-4 files in that directory from the
following URL:
rtmp://public-dns/vod/mp4:filename.xxx
See On-demand streaming.

Using Adobe Media Server on Amazon Web Services
Set content permissions
Adobe Media Server on Amazon Web Services instances run CentOS, which is a Linux distribution. On Linux, all files
and directories belong to an owner and a group. All Adobe Media Server files and directories belong to
amsuser:amsgroup.
When you upload content to an instance, change the content’s owner and group to amsuser:amsgroup. Changing the
owner and group to amsuser:amsgroup ensures that the server can access and manipulate the content. To change the
owner of all content in a directory to amsuser:amsgroup, use the following command:
chown amsuser:amsgroup *
For more information, see Understanding Linux file permissions.
Using key pairs to connect to an instance securely
To connect to a instance, use an SSH client such as WinSCP, OpenSSH, PuTTY, or Terminal. SSH is a network protocol
that allows you to connect two devices securely.
For a list of SSH clients and which platforms and protocols they support, see Comparison of SSH clients on Wikipedia.
Instead of using a password, SSH clients use a key pair to verify their identity with the server. When you launch a Adobe
Media Server on Amazon Web Services instance, you generate and download a key pair. A key pair consists of a public
key and a private key. The instance has a copy of the public key and you download the private key as a .pem file. Set the
permissions of the .pem file used for authentication on Linux or Unix machines as 0400, using chmod 0400
filename.pem command. When you connect to the instance, pass the .pem file to the server so it can verify that the
private key matches the public key.
Some SSH clients, such as WinSCP, cannot read .pem files. To use these clients, use the PuTTYgen application to
convert the .pem file to a .ppk file that the client can read. The following sections explain how to convert a file.
Adobe Media Server on Amazon Web Services instances run on CentOS which is a Linux distribution. You can connect
to instances from Linux operating systems, Mac OS®, Windows, and from any other operating systems that support
SSH.
For more information about key pairs, see Using Public Keys for Authentication.
Connect to an instance and copy files from a Windows computer
Note: Some companies block SSH access. If you can’t connect to an instance, contact your server administrator for SSH
access.
On a Windows computer, you can use either of the following:
• WinSCP
WinSCP is a free SSH, SCP, and SFTP client. It has a graphical interface that you can use to copy files from a local
computer to a remote computer.
• PuTTY
Last updated 8/28/2014
33
Using Adobe Media Server on Amazon Web Services
PuTTY is a free SSH client. From the PuTTY FAQ, “In really simple terms: you run PuTTY on a Windows machine,
and tell it to connect to (for example) a Unix machine. PuTTY opens a window. Then, anything you type into that
window is sent straight to the Unix machine, and everything the Unix machine sends back is displayed in the
window. So you can work on the Unix machine as if you were sitting at its console, while actually sitting somewhere
else.”
Note: You can use other SSH clients as well. This document provides instructions for WinSCP and PuTTY, but other clients
work similarly.
Use WinSCP to connect to an instance and copy files
The following example uses the WinSCP SCP client for Windows.
1 Download and install WinSCP and PuTTYgen.
2 Open PuTTYgen and do the following:
a Choose Conversions > Import Key.
b Browse to the .pem file and click Open.
c Choose File > Save Private Key.
A dialog asks whether it’s OK to save this file without a passphrase to protect it. Click Yes.
d Give the file the same filename as the .pem file and click Save. PuTTYgen adds the .ppk file extension.
e Close PuTTYgen.
3 Login to the AWS Management Console, and select the instance to which you want to connect. In the details pane,
copy the Public DNS entry.
4 Open WinSCP and do the following:
a With Session selected in the tree, paste the public DNS of your instance to the Host name field.
b Verify that the Port number is 22.
c For User name, enter amsadmin.
d Click ... to browse to a private key file. Select the .ppk file you created in PuTTYgen and click Open.
e For File protocol, select SCP.
f
To save the settings, click Save, give the profile a name, and click OK.

The following example uses the PuTTY SSH client for Windows. The PuTTY SSH client is available on other operating
systems, as well.
For a video walkthrough of these steps, see Using AWS Management Console with Amazon EC2. The instructions for
connecting to an EC2 Linux instance with PuTTY and generating a .ppk file start at the 3 minute 45 second mark.
1 Download and install PuTTY and PuTTYgen.
2 Open PuTTYgen and do the following:
a Choose Conversions > Import Key.
b Browse to the .pem file and click Open.
c Choose File > Save Private Key.
A dialog asks whether it’s OK to save this file without a passphrase to protect it. Click Yes.
d Give the file the same filename as the .pem file and click Save. PuTTYgen adds the .ppk file extension.
e Close PuTTYgen.
3 Login to the AWS Management Console, and select the instance to which you want to connect. In the details pane,
copy the Public DNS entry.
4 Open PuTTY.
5 With Session selected in the tree, paste the public DNS of your instance to the Host Name (or IP address) field.
6 In PuTTY, in the left-hand tree, expand Connection > SSH > Auth.
7 Click Browse to locate the .ppk file you just generated, and click Open.
8 Click Open at the bottom of the window to connect to your Adobe Media Server on Amazon Web Services instance.
PuTTY may display a Security Alert. Read the alert and click Yes or No.
9 At the login prompt, enter amsadmin and press Enter.
You don’t need to enter a password, the .ppk file handles authentication. You should see an AMS banner and a
prompt.
10 To manage content, use Bash commands. For information about where to put files to stream, see Where to store
content on an instance .
Connect to an instance and copy files from a Linux/UNIX computer
Note: Some companies block SSH access. If you can’t connect to an instance, contact your server administrator for SSH
access.
Most Linux/UNIX machines have an SSH client, called a shell. On Mac OS, the shell application is called Terminal. In
the shell, use the scp command to securely copy files to a Adobe Media Server on Amazon Web Services instance.
If your machine doesn’t have an SSH client, you can download one at http://www.openssh.org.
Connect to an instance
1 Open a shell.
2 Ensure that the permissions of the .pem file used for authentication on Linux or Unix machines is 0400. To set the
permissions, use chmod 0400 filename.pem command.

Otherwise a warning is generated and you cannot log in.
3 Use the ssh command to connect to an instance. Use the following syntax:
ssh -i keypair.pem amsadmin@public-dns
For example, the following command connects to an instance:
ssh -i /Users/AMS/Documents/amsdocs4.pem amsadmin@ec2-50-16-19-38.compute-1.amazonaws.com
Note: Log in to the Adobe Media Server instance as amsadmin.
Copy content to an instance
1 Open a shell.
2 To copy files to a directory on the instance, use the scp command. following command:
scp -i keypair.pem fileToUpload.xxx amsadmin@public-dns:/remote/dir/toUpload
For example, the following command copies the file sample.f4v to the vod application on the instance:
scp -i /Users/AMS/Documents/amsdocs4.pem /Users/AMS/Documents/sample.f4v amsadmin@ec2-50-16-1938.compute-1.amazonaws.com:/mnt/applications/vod/media
For information about where to put files to stream, see Where to store content on an instance and Tutorials: on-demand
and live streaming .
Using Amazon Simple Storage Solution (S3) to store content
According to the Amazon web site: Amazon S3 provides a simple web services interface that can be used to store and
retrieve any amount of data, at any time, from anywhere on the web. It gives any developer access to the same highly
scalable, reliable, secure, fast, inexpensive infrastructure that Amazon uses to run its own global network of web sites.
Create an Amazon S3 account to store content. Adobe Media Server on Amazon Web Services installs with
FuseOverAmazon (s3fs) which allows you to mount an S3 bucket as a local file system on the Adobe Media Server
instance. Copy files from the S3 bucket to the /mnt/applications/vod/media directory to stream them from the vod
application. Copy the files back to the S3 bucket before you terminate the instance.
Note: Technically, it is possible to stream files from an S3 bucket. However, Adobe does not recommend it because
performance may suffer. It is not technically possible to record files to the S3 bucket.
Mount an S3 bucket as a local file system
1 Create an Amazon S3 account at aws.amazon.com/s3.
2 Create an S3 bucket and upload media to it.
See Amazon Simple Storage Service Getting Started Guide.
3 FuseOverAmazon (s3fs) is installed on the Adobe Media Server on Amazon Web Services instance.
FuseOverAmazon mounts the S3 bucket as a local file system on the instance.
For information about the FuseOverAmazon command line options, see FuseOverAmazon.
4 Locate your Access Key ID and your Secret Access Key.
See Using Credentials > How to Get Your Access Key ID and Secret Access Key in the Amazon Web Services User
Guide.
5 Create a directory on the instance to mount the S3 bucket, for example, /mnt/s3fs.
Last updated 8/28/2014

Using Adobe Media Server on Amazon Web Services
Create the directory as a subdirectory of the /mnt directory because it contains the most storage space.
6 Open a shell and issue the following command:
echo "accessKeyId:secretAccessKey" >> /etc/passwd-s3fs
chmod 640 /etc/passwd-s3fs
/usr/local/bin/s3fs ams-test-s3fs -o use_cache=/tmp -o allow_other,uid=500,gid=500
/mnt/s3fs
The amsuser:amsgroup can now read and write content to the S3 bucket “ams-test-s3fs”.
Note: The “allow_other” option allows Adobe Media Server to read directly from the s3fs mounted device. If you don’t
specify “allow_other”, Adobe Media Server cannot access files from the s3fs mount. Also, you must specify the full path
to s3fs.
Use a shell script to manage content when you launch an instance
Note: Using a shell script is optional. You can copy and manage content manually if you choose.
When you launch an instance, there is a User Data text box on the Advanced Instance Options screen. Scripts in the
User Data text box that start with #! are run at runlevel 5 when an instance launches. The User Data text must be less
than 16KB. To run a longer script, write it in an external file and trigger it from the User Data script. The last line of the
User Data script in this example triggers an additional script.
1 Complete steps 1-4 in the previous task.
2 Enter the following script into the “User Data” text box when you launch an instance from the AWS Management
Console. When the instance loads, it mounts the S3 bucket “ams_scripts” and executes the script “setup.sh”.
#! /bin/sh
echo "accessKeyId:secretAccessKey" >> /etc/passwd-s3fs
chmod 640 /etc/passwd-s3fs
mkdir /mnt/bucket
/usr/local/bin/s3fs ams_scripts -o use_cache=/tmp -o allow_other,uid=500,gid=500
/mnt/bucket
/mnt/bucket/setup.sh
Use the full path to s3fs.
The option -o use_cache=/tmp is an s3fs feature that caches S3 content on the instance. When you specify this
option, s3fs can use local content instead of pulling it from S3 each time the content is requested.
The /mnt/bucket/setup.sh script is a file on S3 that runs additional configuration steps. For example, the script could
modify Adobe Media Server to look for streams in the /mnt/bucket directory. The script is not provided; you must
write it.
For additional information about User Data scripts, see Eric Hammond’s article Automate EC2 Instance Setup with
user-data Scripts.

Using Adobe Media Server on Amazon Web Services
Using Amazon Elastic Block Store (EBS) to store and stream content
According to the Amazon web site: Amazon Elastic Block Store (EBS) provides block level storage volumes for use with
Amazon EC2 instances. Amazon EBS volumes are off-instance storage that persists independently from the life of an
instance. Amazon Elastic Block Store provides highly available, highly reliable storage volumes that can be attached to a
running Amazon EC2 instance and exposed as a device within the instance. Amazon EBS is particularly suited for
applications that require a database, file system, or access to raw block level storage.
Amazon EBS works exactly like a local file system. You can stream from an EBS volume and write to an EBS volume.
The main benefit of using an EBS volume is persistent storage; when you terminate an instance, the data on the EBS
volume is saved.
Note: To prevent data loss, unmount the EBS volume before you terminate the instance.
The drawback of a local disk is that you can attach it only to a volume in the same zone. Also, you can attach only one
instance to an EBS volume. You cannot boot Adobe Media Server from an EBS volume.
To create an EBS volume and attach it to a Adobe Media Server instance, do the following:
1 Sign in to your Amazon Web Services account at https://console.aws.amazon.com/ec2.
The AWS Management Console launches with the EC2 tab open.
2 In the AWS Management Console, in the Navigation pane, locate Elastic Block Store and click Volumes.
3 In the upper right corner of the EBS Volumes pane, click Help.
A Help panel opens with complete instructions for creating, attaching, formatting, and mounting a volume.
Working with applications
Working with pre-built applications
Adobe Media Server installs with four pre-built applications (also called streaming services). The tutorials in the section
Tutorials: on-demand and live streaming use these applications. The following table describes each application:
Application name
Description
vod
This application plays on-demand media files. To configure the
storage location for the media files, see Where to store content on an
instance.
See On-demand streaming.
live
This application broadcasts a live stream and doesn’t record it.
See Live streaming.
multicast
This application multicasts a live stream and doesn’t record it.
See Multicast streaming.
livepkgr
This application broadcasts a live stream over HTTP and doesn’t record
it. See Live HTTP Dynamic Streaming.
To record a stream, see Publish and play a single live stream over
HTTPin Adobe Media Server Developer’s Guide.

Using Adobe Media Server on Amazon Web Services
For more information about the pre-built applications, see Streaming services in the Adobe Media Server Developer’s
Guide.
Create an application
To create an new application, create a directory in the /mnt/applications directory. For example, to create an application
called myapplication, create the following directory:
/mnt/applications/myapplication
Working with applications on Adobe Media Server on Amazon Web Services is no different than with other editions
of Adobe Media Server. For complete documentation, see Adobe Media Server Developer's Guide.
Configure an application
All applications use the default configuration files located in the following directory:
/opt/adobe/ams/conf
To configure a single application, copy an Application.xml file to the applications’s directory. For example, to configure
myapplication, copy the Application.xml file to the following location:
/mnt/applications/myapplication/Application.xml
You can place an Application.xml file in an application’s folder. Values set in the application-level Application.xml file
override the values in the vhost-level Application.xml file. The vhost-level Application.xml file configures all
applications in a vhost (virtual host). By default, an instance has one virtual host. The vhost-level file is located here:
/opt/adobe/ams/conf/_defaultRoot_/_defaultVHost_/Application.xml
To see an example of configuring a single application, look at the vod and live applications included with Adobe Media
Server. Navigate to /mnt/applications/vod and /mnt/applications/live. Each folder contains an Application.xml file. The
values in these files override the values in the vhost-level file.To prevent settings in the vhost-level Application.xml
settings from being overridden by the application-level Application.xml file, add an override attribute to a tag and set
it to "no", as in the following:
<LoadOnStartup override="no">false</LoadOnStartup>
When override="no" for an element in a vhost-level Applcation.xml file, you cannot override that element, or any
elements contained within that element, in an application-level Application.xml file.
Connect to an application
To connect to the application, use the ActionScript 3.0 NetConnection class:
netconnection.connect(protocol://public-dns/myapplication)
The value of protocol can be any protocol supported by Adobe Media Server. For a complete list, see the Adobe Media
Server Technical Overview.
The value of public-dns is the public DNS entry of the instance. To find this value, select the instance in the AWS
Management Console and look in the details pane.
The value of myapplication is the name of the folder you created in the /mnt/applications directory.
For more information about connecting to an application and streaming media, see Developing streaming media
applications in Adobe Media Server Developer’s Guide.

Record a live event
You can record archives of live events just as you would with any edition of Adobe Media Server that supports
recording. To store the archives, copy them from the instance to a storage volume (either EBS or S3) before you stop or
terminate the instance.
To record a live stream, use the DVRCast application. For more information, see Live streaming with DVR.
