The abstractions that Eureka provides for this are Virtual IPs (VIPs) for insecure communication, and Secure VIPs (SVIPs) for secure. There is a downside to fetching this data on-demand: this adds latency to the first request to a cluster. This is the first in a series of posts on our journey to service mesh, so stay tuned.

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.

Unfortunately, this means that the age-old Telco bugbears will rear their ugly heads again, including latency. 5G, as a fundamental requirement, mandates a 1 millisecond latency from the datasource to its destination. In fact, 5G has plenty of valid use cases, one of which is virtual reality. This requires 1 ms network latency.

Performant – DynamoDB consistently delivers single-digit millisecond latencies even as your traffic volume increases.

However in the Skylake microarchitecture (you can see a list of CPUs here ) the PAUSE instruction changed and in the documentation it says “the latency of the PAUSE instruction in prior generation microarchitectures is about 10 cycles, whereas in Skylake microarchitecture it has been extended to as many as 140 cycles.”

Again, the benefit being that the code within your containers or virtual machines is managed by the cloud provider. Developers don’t have to put in additional time to fine-tuning the system, or rely on other teams for support, as it’s done automatically with the cloud provider. Focus on Application Development.

Fast forward a few years after Azure SQL Database was released to when Azure SQL Managed Instance was in public preview, and "vCores" (virtual cores) were announced for Azure SQL Database. Overall, the 72 vCore size can provide more CPU performance than the 80 vCore Gen 5 by providing a lower CPU latency and higher clock speeds.

Additionally for the log disk component it is latency for an individual write that is crucial rather than the total I/O bandwidth. The first example shows a data load, the second a TPC-C based workload with 5 virtual users and the 2nd example with 10 virtual users. A good example of how tuning is an iterative process.
