Virtual consensus in Delos , Balakrishnan et al. Back in 2017 the engineering team at Facebook had a problem. While ultimately this new system should be able to take advantage of the latest advances in consensus for improved performance, that’s not realistic given a 6-9 month in-production target.

CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. Note that Ubuntu also has a frame to show entry into vDSO (virtual dynamic shared object). Microbenchmark os::javaTimeMillis() on both systems. Running this on the two systems saw similar results. Try changing the kernel clocksource.

Back on December 5, 2017, Microsoft announced that they were using AMD EPYC 7551 processors in their storage-optimized Lv2-Series virtual machines. I wrote about using CPU-Z to benchmark the Intel Xeon E5-2673 v3 processor in an Azure VM in this article. Figure 1: CPU-Z Benchmark Results for LS16v2. 10 x 1.9TB NVMe SSD.

since 2017, and many customers have used it with great success while we collected requirements for the next iteration of our Lambda extension. The virtual CPU is turned off. Lambda functions often serve as a gluing tier or a gateway from on-premises systems to AWS services; they’re almost never standalone.
