Besides the traditional system hardware, storage, routers, and software, ITOps also includes virtual components of the network and cloud infrastructure. A network administrator sets up a network, manages virtual private networks (VPNs), creates and authorizes user profiles, allows secure access, and identifies and solves network issues.

There shouldn't be any jitters (either in the cluster or on disk), and no hotspots, slow queries, or network fluctuations. Through a chain reaction of events, the CPU load maxes out, out of memory errors occur, network latency increases, and disk writes and reads slow down. However, reality is often unsatisfactory.

This failure in replication could happen due to crashes, network partitions, or other situations where failover occurs.

Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.

AWS Lambda is a serverless compute service that can run code in response to predetermined events or conditions and automatically manage all the computing resources required for those processes. You will likely need to write code to integrate systems and handle complex tasks or incoming network requests. What is AWS Lambda?
