Richard Thaler won the 2017 Nobel prize in Economics for his work on Behavioral Economics. Virtualization, for instance, was being addressed by IBM in the 1960s. Both virtualization and power burst onto the architecture community seemingly out of nowhere even though there was a clear historical basis and trend for both.

CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. This server is spending about a third of its CPU cycles just checking the time! Note that Ubuntu also has a frame to show entry into vDSO (virtual dynamic shared object). This was much worse many years ago on Xen virtual machine guests.

Search for recent blog posts on Linux containers, and try them out, and you'll piece together their capabilities and workings bit by bit. Oracle VM Server is based on Xen. There's a lot about Linux containers that isn't well documented yet, especially since it's a moving target.

Correspondingly, 3GB functions should see a 2x CPU performance improvement over 1.5GB Lambdas, but this is through doubling the number of cores the function has access to, rather than double the virtualized time-slices. We haven’t tried out SAR yet since it was only pre-announced, but when we do we’ll give an update here, on the blog.

This blog highlights considerations for keeping your own PostgreSQL databases highly available and healthy. HA in PostgreSQL databases delivers virtually continuous availability, fault tolerance, and disaster recovery. When the primary server fails, a standby server takes over as the new primary.

We’re no longer living in an age where large companies require only physical servers, with similar and rarely changing configurations, that could be manually maintained in a single Datacenter. We went from managing five EC2 instances in 2011 to around 1,000 in 2017. The post Everything as Code appeared first on Dynatrace blog.

since 2017, and many customers have used it with great success while we collected requirements for the next iteration of our Lambda extension. Much of what’s covered in this blog post is taken from that talk. The virtual CPU is turned off. In a future blog post, we’ll explain how to interpret Lambda metrics.
