So your MySQL server has crashed. What do you do now?

As I interface with large clients as a Technical Account Manager (TAM) at Percona, one thing I have noticed is the evolution of the DBA role. With the rise of the cloud, DBAs seem to be spending less time doing traditional DBA roles of performance tuning, configuring backups, and so on. Instead, DBAs are moving […]

So, what do you do when you love technology but are ready for a change in the day-to-day activities of a DBA? One consideration is to become a Technical Account Manager, or TAM for short. At Percona, a TAM is an account manager who is also technical (the big “T” in TAM). While everyone’s path […]
In your organization, who decides what database platform will be utilized for that new application being built? For many groups, that decision is made by the Development Team while for others, it is the Database Team. But, which is best equipped to make that decision?

One thing that comes up often from working with a variety of clients at Percona is “How can I achieve a Disaster Recovery (DR) solution with Percona XtraDB Cluster (PXC)?” Unfortunately, decisions are sometimes made with far-reaching consequences by individuals who often do not well understand the architecture and its limitations.
