Almost all the projects we work on are cloud based applications. A common question that crops up every time we start looking to use serverless components in any project is which one??

Migrating an existing WebAPI into Serverless functions!
We have been dabbling with Serverless computing for sometime now . Recently we decided to check if it made sense to convert an existing customer’s WebAPI into a set of serverless functions.

Using the Azure Support Portal to diagnose a CPU Spike!
In one of our recent projects we had alerts set up for CPU and memory spikes. The CPU alert was set at 10% and 50%. While we got the 10% alert periodically when the app was in active usage , we also got a few 50% alerts once in a while which would get resolved […]
How we almost killed our Azure Deployment by diagnosing it!

Recently while checking the health of one of our production deployments we […]

Deciding to go the route of Node+socket.io for scalable and performance oriented service we started with the official socket.io tutorial at (http://socket.io/get-started/chat/). That worked wonderfully . As the next step we went ahead and hosted it on Azure! Here is what the socket told us! […]
