If we were to select the most important MySQL setting, if we were given a freshly installed MySQL or Percona Server for MySQL and could only tune a single MySQL variable, which one would it be? To be fair, that is also true with PostgreSQL; it hasn’t been tuned either, and it, too, can also perform much better.

Virtualization has revolutionized system administration by making it possible for software to manage systems, storage, and networks. With the self-service features and an everything-as-code architecture, labor requirements will significantly decrease and SRE best practices will emerge. Design, implement, and tune effective SLOs.

The abstractions that Eureka provides for this are Virtual IPs (VIPs) for insecure communication, and Secure VIPs (SVIPs) for secure. In this architecture, service to service communication no longer goes through the single point of failure of a load balancer. It’s been a great experience working with you all on this.

A scalable architecture needs to distribute work across many threads in order to facilitate all the CPUs of a physical or virtual machine. Locking is the Achilles heel of any multi-threaded architecture. Use case #1: Identify scalability issues. Ideally, all CPUs would execute code all the time and never be idle.

For Virtual Machine (VM) installations you may need to consult the VM documentation for support capabilities. For example, setting the virtual machine reserve percentage to 100% provides a hard affinity like capability to a Hyper-V based VM. SQL Server uses Windows APIs to determine the processors and package interactions.

If tuned for performance, there is a good change reliability is compromised - and vice versa. In some cases, this can be enhanced by combining data virtualization techniques with microservices architecture.
