About Me

Hello and welcome to my database blog

For those who are interested to find out more about me:

I’m Justin John, an enthusiastic and knowledgeable Database Architect and DBA with 19 years of Oracle and MS SQL and MySQL experience. Managed many large end-to-end database implementations with High Availability database solutions in Oracle , SQL Server, MySQL. I started this blog to present some of the interesting things I encountered during career. It is very interesting to see how database technologies evolve over time from RDBMS, NoSQL, Distributed etc and  how data center concept change from large on-premisses to cloud environment. Most recently many of the database implementation I’m involved are Cloud (OCI,AWS) environment. It is amazing too see how fast we can get DB servers up and runing in the cloud compared to months of wait time few years back. It is also challenging to architect the systems now because we do have so many option to choose from based on the application requirement.
