Chapter 1: Getting started

Adobe® Media Server (AMS) on Amazon Web Services is a pre-configured instance of Adobe Media Server Extended

running on hardware in the Amazon Elastic Compute Cloud (EC2). Use Adobe Media Server on Amazon Web

Services to stream live and on-demand media to Adobe® Flash® Player and Adobe® AIR®.

Note: The latest AMS version available on AWS is AMS 5.

To get started, complete the tasks in “Create an account and connect to the server” on page 1. Then complete the

“Tutorials: on-demand and live streaming” on page 6 to start streaming media.

To watch a video of an Amazon Web Services Evangelist explaining how to create an account and connect to the

server, see Using the AWS Management Console with Amazon EC2.

Create an account and connect to the server

Create an Amazon Web Services account and order Adobe Media Server

1Sign up for an Amazon Web Services (AWS) account at aws.amazon.com/ec2/.

For detailed instructions, see Sign up for EC2 in “Amazon Elastic Compute Cloud Getting Started Guide”.

2To order Adobe Media Server for Amazon Web Services with your AWS account, go to

www.adobe.com/go/learn_fms_aws_order_en.

3Read the pricing terms and click Place your order.

There is a $5.00 monthly subscription fee. This fee allows you to run an unlimited number of Adobe Media Server

instances. In addition to the monthly subscription fee, there is a fee for hourly usage and a fee for data transfer.

Note: Read the product license agreement at adobe.com/products/eulas/.

Launch an instance of Adobe Media Server

To start using Adobe Media Server on Amazon Web Services, launch a virtual server, known as an Amazon EC2

instance.

For additional information and screenshots, see Launch an Instance in “Amazon Elastic Compute Cloud Getting

Started Guide”.

1Sign in to your Amazon Web Services account at https://console.aws.amazon.com/ec2.

The AWS Management Console launches with the EC2 tab open.

2In the AWS Management Console, click Launch Instance.

3Click Community AMIs (Amazon Machine Images).

According to Amazon, “An Amazon Machine Image (AMI) contains all the information needed to create a new

instance of a server. For example, an AMI might contain all the software to act as a web server (e.g., Linux®,

Apache, and your web site), or all the software to act as a Windows® database server (e.g., Windows and SQL Server).”

4Locate the latest Adobe Media Server AMI IDs on this page.

USING ADOBE MEDIA SERVER ON AMAZON WEB SERVICES

Getting started

Last updated 9/20/2013

5From the Amazon Machine Images (AMIs) page, locate the AMI in the Community AMI pane and click Select.

Optionally, you can search for the AMI ID and locate the AMI.

6On the Instance Details screen, do the following and click Continue:

•Enter the number of instances.

•Select the Availability Zone of the server hosting the instance.

•Select the Instance Type.

The instance type determines the number of RTMFP connections that the server supports. See “Supported Flash

Media Server features” on page 21. The instance type also determines the pricing.

•Leave Launch Instances selected.

Note: Adobe Media Server on Amazon Web Services does not support Spot Instances or Virtual Private Clouds (VPC).

7On the Advanced Instance Options screen, do the following and click Continue:

•Select the default Kernel ID.

•Select the default RAM Disk ID.

•You can optionally enable CloudWatch Monitoring. CouldWatch Monitoring may incur additional charges.

•You can optionally copy a shell script to the User Data field. The shell script runs when the instance launches.

See “Using Amazon Simple Storage Solution (S3) to store content” on page 35.

8Adobe Media Server does not require that you add any tags. However, you may choose to add tags. Use the value

of the Name tag to identify the instance in the AWS Management Console, for example, you could the Name value

to My First AMS Instance. Click Continue.

9Do one of the following to choose a Key Pair, and click Continue:

•If you’ve already created a key pair, you can Select Choose from your existing Key Pairs. Select a key pair from

the drop-down list. You can use one key pair for an unlimited number of instances.

•Select Create a new Key Pair. Enter a name for the key pair. Click Create & Download your Key Pair. Save the

.pem file to a safe place on your computer and click Continue.

From the Amazon documentation, “A key pair is a security credential similar to a password, which you use to

securely connect to your instance once it's running. If you're new to Amazon EC2 and haven't created any key pairs

yet, when the wizard displays the Create Key Pair page, the Create a new Key Pair button is selected by default.” For

general information about key pairs, see Using Public Keys for Authentication.

10 Select Create a new Security Group. A Security Group is a firewall. Do the following to define how clients can

connect to the instance:

Note: If you’ve already defined a Security Group for Adobe Media Server instances, you can select it. You can use one

Security Group for an unlimited number of instances. When an instance is running, you cannot change the Security

Group it belongs to. However, you can modify the rules of a Security Group at any time.

aSelect HTTP from the pop-up menu and click Add Rule.

bSelect SSH from the pop-up menu and click Add Rule.

Create a Security Group in the Request Instances wizard.

Important: To stream media, you must open port 1935 for the RTMP protocol for TCP and UDP. You cannot add

this rule in the Request Instances wizard. You will add it in the AWS Management Console.

11 Review the information for the instance. When you’re satisfied with the settings, click Launch.

Your instances may take a few minutes to launch. Click View your instances on the Instances page to go to the AWS

Management Console.

Note: From the Amazon EC2 FAQ: It typically takes less than 10 minutes from the issue of the RunInstances call to

the point where all requested instances begin their boot sequences. This time is dependant on a number of factors

including: the size of your AMI, the number of instances you are launching, and how recently you have launched that

AMI. Images launched for the first time may take slightly longer to boot.

12 To add port 1935 to the Security Group, do the following:

aIn the AWS Management Console, in the Navigation pane, click Security Groups.

bSelect the Security Group you want to modify.

cSelect Connection Method: Custom, Protocol: TCP, From Port: 1935, To Port: 1935, Source (IP or Group):

0.0.0.0/0 and click Save.

Public DNS entry in the AWS Management Console.

3Open a web browser and paste the public DNS into the address field:

http://public-dns

For example, the address will look something like this:

http://ec2-184-72-81-199.compute-1.amazonaws.com

The Adobe Media Server Start Screen loads and begins streaming content.

4If the Start Screen doesn’t load or stream content, do the following:

•Verify that the instance is running in the AWS Management Console. In the My Instances panel of the console,

the Status column should have a green light and say “running”.

•Verify that the correct Allowed Connections are set. For information about which connections to allow, see

“Modifying a Security Group” on page 22.

Tutorials: on-demand and live streaming

Important: When you terminate an instance, any changes you made to the instances and any content you copied to the

instance are permanently deleted. Copy content from the instance to an S3 bucket or an EBS volume before you terminate

the instance.

On-demand streaming

Flash Player 10.1, AIR 2

Adobe Media Server on Amazon Web Services has a built-in vod application that streams video on demand content

to video players running in Flash Player and AIR. These tutorials use video players built with the Open Source Media

Framework (OSMF). OSMF simplifies the development of video players for the Flash Platform.

The first tutorial uses a video player called Flash Media Playback. Flash Media Playback is hosted by Adobe and you

can embed it into any web page.

The second tutorial uses a video player called Strobe Media Playback. Host Strobe Media Playback on your own web

server.

On-demand streaming with Flash Media Playback

1Log in to AWS Management Console and do one of the following:

•If you already have an instance running, in the Navigation pane, click Instances.

•If you don’t have an instance running, follow the steps to “Launch an instance of Adobe Media Server” on

page 1.

2In the AWS Management Console, select the running instance and copy the Public DNS from the details pane.
