Why Not Call Database DevOps Simply DevOps?
Category:

Sometimes people are annoyed by the term ‘Database DevOps’. Why not call it simply ‘DevOps’? After all, Database DevOps follows the same core principles.
The answer is simple: implementing DevOps is tricky by itself, but most teams are set up to fail when it comes to implementing DevOps for databases. This makes it worth defining as a specialization.
The Difference Between DBAs, DBREs, and Data Engineers

, database-administration
Twenty years ago, database administrators (DBAs) were the primary career path when it came to specializing in data management.
Much has changed: development patterns transformed from Waterfall to Agile, DevOps drives automation and shared ownership of code, and cloud services have made many more kinds of PaaS databases, data lakes, and data lakehouses available to organizations of all sizes.
These changes have introduced new and varied career paths for data folks which have different emphases on skill sets. In this post, I talk through the commonalities and differences between DBAs, Database Reliability Engineers (DBREs), and Data Engineers (DEs). Whether you’re a hiring manager or data professional, it’s worth knowing about these roles.
Should We Do Index Maintenance on an Azure SQL Managed Instance or Azure SQL Database?
Have you ever received advice that was technically correct, but it was too hard to understand?
I think of this as “accidental bad advice,” because it can lead to confusion and bad outcomes. There’s a LOT of accidental bad advice out there on index maintenance for SQL Server and cloud versions like Azure SQL, even in the official documentation.
In this post I’m answering a common index maintenance question, and we’re going to keep it simple.

What I found was worse than what I’d imagined. As a data person, it made me feel sad and icky.
