Amazon Pushed the Bar. Again!

Everybody is talking these days about iPad, Windows Phone 7, iPhone OS4 and Nexus One and how they gonna change the world. Well if everybody is going to change the world, they need reliable servers and more important traffic efficient communications that will enable mobile application keep updated while consuming as few as possible battery and network resources. If you look for the right buzz Google for COMET, Push and Long Polling.
Current State
Well to be honest, the COMET Servers market state is not so good. Most of the products in the market are either young or luck important features such as high availability. However, I'll keep the full details of the market state to survey that will be exposed in the next few days.
The Amazon Move
Amazon detected this new hot market and exposed today SNS: Simple Notification Service. This service provides you the ability to push data to your clients without taking care of establishing the server infrastructure and taking care of HA.
As a first impression I can say the pricing is very attractive (100K first messages are free) and even the beta limit of 100 topics (channels) is valid for many application (yes I know, there are many of us who needs XXXK :-)
UPDATE: at a second impression this product (SNS) still do not support the need for a push.
The bottom line
If you are a mobile developer, take a look at this new service. It can save you a lot of TTM.

The Amazon SNS API includes the following API:
  1. Topics: Create, Delete and List channels and Set and Get their attributes.
  2. Topics Permissions: Add and Remove permissions on the channel to AWS accounts
  3. Subscription: Subscribe and Unsubscribe to a channel and subscription confirmation. Subscription is done to URL (http and https), Email account and SQS. Subscription cannot be done using COMET method or other methods that are feasible for mobile subscriber (unless you gonna poll your email account)
  4. Publish: Publish a new info item into the channel.
What is missing? the push mechanism that can support mobile and web clients and notify them regarding new info items.

The Real Bottom Line
Read the full Spec and the API before posting to your blog :-)

Keep Performing,
Moshe Kaplan
