Serverless is more than a trend, today all the major cloud providers have a serverless offering on their platform, many books have been written on the subject and businesses around the world are using the power of severless daily.

There isn’t any difference when it comes to NoSQL.

The session will cover all major NoSQL database types and look at the two or three main issues of each to be aware of and how to solve them.
