Some time ago the Application Insights became available as a preview in the Azure portal. Application Insights helps you monitor the state of an application, server, clients, etc. As said, it’s still in preview, but it’s rather stable and very easy to use and implement in your applications.
The documentation is still being worked on, but with all the getting started guides on the Microsoft site you can kick start your project with it in a couple of minutes.

This is where the Elastic Scale Split Merge tool comes in place. The team has created a nice web application which will enable you to do this kind of management.

One of these differences is the (guaranteed) uptime and the latency between the different servers. When creating your local on-premise datacenter you will have a pretty stable network connection between the different servers and it’s probably really fast. The cloud can be pretty fast also, especially when you are located in the same datacenter/container.

At the moment there are 2 sample applications available, one using plain old SQL-queries (ADO.NET) and another one using the Entity Framework. I would suggest checking out these samples before doing any serious Elastic Scale work.
You will probably notice there are some small differences between the ADO.NET sample and the Entity Framework sample.

This is something you will want to store in a single location, so you know for sure you are always using the most recent information. When using the Elastic Scale libraries this is called the Shard Map Manager. The Shard Map Manager keeps track of the location & state of the shardlets and shards.
