For a long time I blame Microsoft for not really understanding the Internet and cloud Industry basic need: very large systems that can handle billions of daily transactions with a very low revenue per transaction. Now, after admitting its failure in the mobile industry (see Kin's death earlier this week), Microsoft finally reveals AppFabric after a very long time (I would like to thank my colleague Alon Biran for notifying me regarding it).
What is AppFabric?
The roots of AppFabric are located in the "Velocity" project that was developed in the SQL Server group (a year and a half ago I wrote a Knol about). This project was aimed to provide a key-value store (super hash) that will be used for two main objectives:
- Instant in memory storage data store (database replacement).
- Shared web session repository that will enable instant failure between web servers (the only Microsoft in house solution till now was using SQL Server as a shared repository)
Who are the Current Players?
The major players in the market these days are open source (Every each of the products has its own unique features, please feel free to comment on this post regarding it):
- Memcached: the #1 product in the market. Its roots are in 2003. It is an open source and Linux based product. Yet, Memcached has .Net client API as well as windows porting of the product itself.
- SharedCache: a native C# open source product that is a Memcached like.
- StateServer: commercial native windows product by ScaleOut Software.
- NCache Express: another commercial native windows product by Alachisoft.
Why Did It Take So Long?
It seems that Microsoft had a major cannibalization issue: If you provide a good key-value store then you may reduce the databases size and usage intensity. Thus, the number of high cost database licenses will be significant lower and the bottom line will be smaller. Oracle has the same problem with Coherence that is now part of the Fusion platform.
Taking this product into RTM is a true Microsoft understanding that if it really want to take a significant role in the Internet and cloud industry, it will have to sacrifice more than just few cents in its financial reports bottom line.
These are very good news that Microsoft is finally provide a solution for a basic need of the Internet and cloud industry. However, while Microsoft was catching up with the Industry 2003 news, new requirements were raised including MapReduce, BigTable and other NoSQL advanced features. How much time will it take this time? Probably only Steve Ballmer has the answer.
