When you want to be successful, you need to run alone and fast. But if you want to run longer, you want to run together. I have personally seen multiple instances where this statement holds true to every word. When working with customers and in various consulting engagements, I have seen it is not enough to just solve the problem. It is important to enable the team working on the project and make them aware of the reasons why it did happen in the first place. I always felt the art of working together will take us a long way.

SQL SERVER – Back to Basics – What is Azure?
Recently I was at a community session talking to a bunch of computer science students about databases and the type of work I have been doing lately in consulting.

Is this a new Database in the industry?”

Understanding Database Scalability – Horizontal and Vertical Scalability Better Together
When I wrote the blog around Understanding Database Scalability – Vertical and Horizontal, I saw few have conversations with me on if it is this or that. And these discussions could take a course all by itself. There is no one size fits all when it comes to scalability.
