Two months ago I wrote about Amazon’s plans for launching a Content Delivery Network (What’s a Content Delivery Network?). Today, Amazon announced CloudFront - “a service designed with ease of use in mind from the very beginning.”

So what does this CDN have to offer?

“Today marks the launch of Amazon CloudFront, the new Amazon Web Service for content delivery. It integrates seamlessly with Amazon S3 to provide low-latency distribution of content with high data transfer speeds through a world-wide network of edge locations. It requires no upfront commitments and is a pay-as-you-go service in the same style as the other Amazon Web Services.

Amazon CloudFront has been designed to be fast; the service will cache copies of the content in edge locations close to the end-user’s location, significantly lowering the access latency to the content. High sustainable data transfer rates can be achieved with the service especially when distributing larger objects.” via Werner Vogels, CTO, Amazon

Sounds pretty cool right? We will definitely be using this at 48Web for a new project we are launching soon… What for? Hosting and serving multimedia, images, and some downloadable material.

Yesterday I wrote about Amazon’s entrance into the Content Delivery Network (CDN) space with their newest web service offering. CDN’s are not a new technology and this is actually a crowded market - one that Amazon hopes to enter and commoditize.

What is a Content Delivery Network?
In layman’s terms a CDN provides the ability to deliver content in a scalable, highly available, and cost-efficient way. If you want a more technical explanation (who does?) here’s what Wikipedia has to offer:

Modern CDN’s can dynamically distribute assets to strategically placed redundant core, fallback and edge servers. Modern CDN’s can have automatic server availability sensing with instant user redirection. A CDN can offer 100% availability, even with large power, network or hardware outages.

Modern CDN technologies give more control of asset delivery and network load. They can optimize capacity per customer, provide views of realtime load and statistics, reveal which assets are popular, show active regions and report exact viewing details to the customers. - via Wikipedia

As I mentioned, Amazon is entering a crowded market with the likes of Akamai, Limelight, and CDNetworks. Luckily they have a good start with their Simple Storage Service (S3) - which will provide the backbone of their new CDN.

How does a content delivery network work?
Here is a simple example…

What does this mean for you?
Ahh the big question… I can just see Doug asking - “All this tech crap is cool but how will this help me?” Well, since you asked I’ll tell you how we use a CDN at 48Web. We don’t use anything fancy at this point - just Amazon S3. Simply enough - we use it to host *stuff* so we don’t have to worry about our websites going down due to the increased load - which helps us scale. We learned this lesson when we launched Iowa Flood (our citizen journalism experiment). Within hours of launching we were getting hit with thousands of requests every few minutes. Needless to say our shared hosting environment for our “experiment” couldn’t handle it. In order to offload most of the strain we moved all the multimedia content to Amazon S3. Our thoughts were “let them worry about handling this load” while we concentrate on our user’s experience.

We also use this in our product development. In order to take the strains off our server we host our images, icons, javascripts, css, etc on S3. This takes the load off our servers and lets it scale much easier. At that point all we need to worry about is how efficient our connectivity is to our database - as we let the CDN take care of all our “assets”. We’re developers - not System Administrators. A CDN gives us a worry free distribution model that is VERY cheap.

How much does this stuff cost?
Current CDN solutions are very expensive but I have a feeling that Amazon is going to completely undercut the CDN market by offering their standard “pay for only what you use” approach which is great. It helps small companies (like us) scale based on demand. Our monthly bill for Amazon S3 is often under $5/mo. I am hoping their CDN can offer similar prices.

Amazon Web Services (AWS) is getting ready to launch a new Content Delivery Service. While there have been little technical details let out they do say the new service will be delivered before the end of the year. This is a natural progression for the Amazon Web Services team as these CDS/CDN’s are growing in popularity as companies figure out how to scale heavy multimedia requirements - from video to podcasts to mobile content.

This new service will provide you a high performance method of distributing content to end users, giving your customers low latency and high data transfer rates when they access your objects. The initial release will help developers and businesses who need to deliver popular, publicly readable content over HTTP connections. Our goal is to create a content delivery service that:

• Lets developers and businesses get started easily – there are no minimum fees and no commitments. You will only pay for what you actually use.
• Is simple and easy to use – a single, simple API call is all that is needed to get started delivering your content.
• Works seamlessly with Amazon S3 – this gives you durable storage for the original, definitive versions of your files while making the content delivery service easier to use.
• Has a global presence – we use a global network of edge locations on three continents to deliver your content from the most appropriate location.

I like that they are building this new service on top of their existing S3 storage infrastructure. Although I am a little confused as of yet what kind of value this brings over just hosting your content on S3 publicly (which is what we do).
