You can now stream live audio or video through AWS using the Adobe Flash Media Server using a cost-effective pay-as-you-go model that makes uses of Amazon EC2, Amazon CloudFront, and Amazon Route 53, all configured and launched via a single CloudFormation template.
We've used AWS CloudFormation to make the signup and setup process as simple and straightforward as possible. The first step is to actually sign up for AWS CloudFormation. This will give you access to all of the AWS services supported by AWS CloudFormation, but you'll pay only for what you use.
I've outlined the major steps needed to get up and running below. For more information, you'll want to consult our new tutorial, Live Streaming Using Adobe Flash Media Player and Amazon Web Services.
Once you've signed up, you need to order Flash Media Server for your AWS Account by clicking here. After logging in, you can review the subscription fee and other charges before finalizing your order:
Then you need to create a Route 53 hosted zone and an EC2 key pair. The tutorial includes links to a number of Route 53 tools and you can create the key pair using the AWS Management Console.
The next step is to use CloudFormation to create a Live Streaming stack. As you'll see in the documentation, this step makes use of a new feature of the AWS Management Console. It is now possible to construct a URL that will open up the console with a specified CloudFormation template selected and ready to use. Please feel free to take a peek inside the Live Streaming Template to see how it sets up all of the needed AWS resources.
When you initiate the stack creation process you'll need to specify a couple of parameters:
Note that you'll need to specify the name of the Route 53 hosted domain that you set up earlier in the process so that it can be populated with a DNS entry (a CNAME) for the live stream.
The CloudFormation template will create and connect up all of the following:
- An EC2 instance of the specified instance type running the appropriate Flash Media Server AMI and accessible through the given Key Pair. You can, if desired, log in to the instance using the SSH client of your choice.
- An EC2 security group with ports 22, 80, and 1935 open.
- A CloudFront distribution.
- An A record and a CNAME in the hosted domain.
The template will produce the URL of the live stream as output:
The resulting architecture looks like this:
The clients connect to the EC2 instance every 4 seconds to retrieve the manifest.xml file. This is specified in the template and can be modified as needed. You have complete access to the Flash Media Server and you can configured it as desired.
Once you've launched the Flash Media Server, you can install and run the Flash Media Live Encoder on your desktop, connect it up to your video source, and stream live video to your heart's content. After you are done, you can simply delete the entire CloudFormation stack to release all of the AWS resources. In fact, you must do this in order to avoid on-going charges for the AWS resources.
The CloudFormation template specifies the final customizations to be applied to the AMI at launch time. You can easily copy and then edit the script if you need to make low-level changes to the running EC2 instance.
As you can see, it should be easy for you to set up and run your own live streams using the Adobe Flash Media Server and AWS if you start out with our tutorial. What do you think?
Update: The newest version of CloudBerry Explorer includes support for this new feature. Read their blog post to learn more.

In 1995 I registered my first domain name and put it online. Back then, registration was expensive and complex. Before you could even register a domain you had to convince at least two of your friends to host the Domain Name Service (DNS) records for it. These days, domain registration is inexpensive and simple. DNS hosting has also been simplified, but it is still a human-powered forms-based process.
 Today we are introducing Amazon Route 53, a programmable Domain Name Service. You can now create, modify, and delete DNS zone files for any domain that you own. You can do all of this under full program control—you can easily add and modify DNS entries in response to changing circumstances. For example, you could create a new sub-domain for each new customer of a Software as a Service (SaaS) application. DNS queries for information within your domains will be routed to a global network of 16 edge locations tuned for high availability and high performance.
Route 53 introduces a new concept called a Hosted Zone. A Hosted Zone is equivalent to a DNS zone file. It begins with the customary SOA (Start of Authority) record and can contain other records such as A (IPV4 address), AAAA (IPV6 address), CNAME (canonical name), MX (mail exchanger), NS (name server), and SPF (Sender Policy Framework). You have full control over the set of records in each Hosted Zone.
You start out by creating a new Hosted Zone for a domain. The new zone will contain one SOA record and four NS records. Then you can post batches of changes (additions, deletions, and alterations) to the Hosted Zone. You'll get back a change id for each batch. You can poll Route 53 to verify that the changes in the batch (as identified by the change id) have been propagated to all of the name servers (this typically takes place within 60 seconds).
The zone's status will change from PENDING to INSYNC when all of the changes have been propagated. You can update your domain registration with the new nameservers at this point. Our Route 53 Getting Started Guide contains a complete guide to getting started with a new Hosted Zone.
Each record in a Hosted Zone can refer to AWS or non-AWS resources as desired. This means that you can use Route 53 to provide DNS services for any desired combination of traditional and cloud-based resources, and that you can switch back and forth quickly and easily.
You can access Route 53 using a small set of REST APIs. Toolkit and AWS Management Console support is on the drawing board, as is support for the so-called "Zone Apex" issue.
Route 53 will cost you $1 per month per Hosted Zone, $0.50 per million queries for the first billion queries per month, and $0.25 per million queries after that. Most sites typically see an order of magnitude fewer DNS queries than page views. If your site gets one million page views per month, it would be reasonable to expect about 100,000 DNS queries per month. In other words, one billion queries is a lot of queries and many sites won’t come anywhere near this number. The results of a DNS query are cached by clients. You could set a high TTL (Time to Live) on the records in your Hosted Zone in order to reduce the number of queries and the cost.
Route 53 supports up to 100 Hosted Zones per AWS account. If you need more, simply contact us and we'll be happy to help.
The Route 53 / CloudFront team has openings for several software developers and a senior development manager.

 Internet telephony and chat service provider Skype is officially launching Skype Connect 1.0 (formerly Skype for SIP), to the public (you can see the release here). The service has been in beta since last year.
Skype Connect allows a business’ employees to make domestic and international calls using regular office telephones (PBX systems) instead of using a computer and a headset for VoIP calls. Users can receive and manage inbound calls from Skype users to SIP-enabled PBX systems, enabling them to offer click-to-call functionality on websites.
Outbound calls from desktop phones to landlines and mobiles worldwide are billed at Skype’s standard per-minute calling rates and users can receive inbound calls from Skype connected users worldwide by placing Skype’s Click & Call buttons on their Web sites. Skype calls to your SIP-enabled PBX are free of charge to people using Skype.
Pricing for the use of the Skype Connect is €4.95 per channel per month with long-distance calls charged at Skype’s standard per minute call rates (with call rounding). Each channel purchased allows for either one inbound or one outbound call at any time. You can buy up to 300 channels per SIP Profile. Skype Connect can be launched and managed via Skype Manager, a web-based tool that allows IT managers to control Skype usage in a company.
Skype says that approximately 37% of Skype users reported that they use Skype for business-related activities and this particular offering could bring significant revenue from the enterprise sector.
Skype, which filed for an IPO earlier this month, is looking for revenue channels and unsurprisingly sees potential in enterprise use of the service. Of course, it should be interesting to see if the rumors pan out and Cisco ends up buying Skype.
