A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. 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). We ended up setting it in the BaseAMI for all cloud services.

those resources now belong to cloud providers, such as AWS Lambda, Google Cloud Platform, Microsoft Azure, and others. Again, the benefit being that the code within your containers or virtual machines is managed by the cloud provider. When code isn’t in use, the cloud providers typically throttle it all the way down.

" Of course, no technology change happens in isolation, and at the same time NoSQL was evolving, so was cloud computing. The requirements for a fully hosted cloud database service needed to be at an even higher bar than what we had set for our Amazon internal system. Auto Scaling is on by default for all new tables and indexes.

In both cases, when using virtually-synchronous replication, the process will require certification from each node and local (by node) write; as such, the number of writes is NOT distributed across multiple nodes but duplicated. It will also allow us to redirect read/write traffic to the primary and read-only traffic to all secondaries.
