It is not very often the internal codename is used when a product is launched; however, when you think about a database designed with global distribution in mind, CosmosDB makes sense.  I was a bit shocked to hear Microsoft was releasing another database technology in 2017; however, the team leading the charge was very impressive and it looked like it was solving problems other database engines could not.  In this episode, we talk with Sidney Andrews about the Cosmos platform, what we can expect from the product and how it differs from SQL Server.  I think you will find the conversation very interesting

Episode Quotes

“[CosmosDB] is a different offering for people whose requirements are slightly different than the traditional relational database.”

“I like to say scale is a configuration setting. It’s not a project anymore.”

“Even for me, as a developer, it took a lot of time and a lot of changing my perspective to really understand what’s going on, but from a DBA perspective, I think your interface is going to be the Data Explorer.”

“The intention is not for Cosmos to be an island, but to be just as much an integrated part of your workflow.”

“You have to know the purpose of the tool and what your needs are and then try to match them appropriately.”
