Instead, you can store the information in a database best suited for that type of data. Forcing one database to handle a workload it wasn't designed to handle can degrade performance and cause other problems. The more issues you can design out before launching products or services, the less chance there is of a future catastrophe.

This means, for example, a financial-trading application developer requires DBAs and database engineers to architect a database that scales easily and avoids problems with latency. To do this, they need to work closely with the developers to write better, more efficient database calls and construct a database that reduces lag to near zero. So, do you still need DBAs? The changing database landscape doesn't eliminate the need for database expertise: It moves the focus of that expertise closer to the design and development side of the application.

Someone needs to not only design and tune the database to support the application, but that person must also understand how to build the modular pieces available in the cloud into a cohesive, scalable unit that meets the needs of the application and the company. This means there are much higher impacts and clearer ROIs realized from efficient database expertise. As the database landscape evolves, valuable DBAs will be less focused on fix-it solutions and more focused on strategy and planning solutions.

DBAs will be asked how the database can contribute to the overall business goals of the company and what solutions there are to help meet those goals.

They will need to help application developers create database calls that not only make sense now but will work at scale. With new technology options such as cloud deployment and containerization, they will need to monitor and constantly reevaluate how applications are working with the database and how to improve performance or incorporate new features or demands from customers without affecting performance.

Finally, as more and more companies use different databases for different applications and scenarios, DBAs will need to continually keep up-to-date on new database trends and technologies in order to remain an expert source of database knowledge. Over the years at Percona, we have seen this shift as well.

The types of issues we face daily have evolved along with the database environment and the role of the DBA. More stable databases, coupled with advances in either homegrown automation or cloud-based infrastructure, reduce the likelihood of general crashing bugs due to the core database software.

Often, today's causes of outages and issues are design decisions, bad code, or odd "edge cases" that weren't considered in the initial planning.

All of this means that the role of the DBA is moving away from simply "keeping it up and running" to a much more strategic position: The DBA is one of the experts that helps enterprises reach their strategic business goals. Today's database administrators are more than the people who keep the lights on—now they are expected to play a strategic role in achieving the business' goals.
