Managing ASP.NET Session State with Amazon
DynamoDB
ASP.NET applications often store session-state data in memory. However, this approach doesn't scale
well. Once the application grows beyond a single web server, the session state must be shared between
servers. A common solution is to set up a dedicated session-state server with Microsoft SQL Server. But
this approach also has drawbacks: you must administer another machine, the session-state server is a
single point of failure, and the session-state server itself can become a performance bottleneck.
Amazon DynamoDB, a NoSQL database store from Amazon Web Services (AWS), provides an effective
solution for sharing session-state across web servers without incurring any of these drawbacks.
Note
Regardless of the solution you choose, be aware that Amazon DynamoDB enforces an item
size limit of 64 KB. None of the records that you store in DynamoDB can exceed this limit.
