A practical solution is Berkeley Packet Filter (BPF), a highly flexible, efficient virtual machine that runs in the Linux kernel. BPF is mainly used for networking, tracing, and security. It allows bytecode to be safely executed in various hooks, which exist in a variety of Linux kernel subsystems.

Regardless of whether the computing platform to be evaluated is on-prem, containerized, virtualized, or in the cloud, it is crucial to consider several essential factors. As database performance is heavily influenced by the performance of storage, network, memory, and processors, we must understand the upper limit of these key components.

While current network speeds may be enough to meet the latency requirements of 4G applications, 5G will necessitate a change, if only because the continental US is ~60ms wide, meaning that a datacenter on one coast communicating with another datacenter on the opposite coast will be too slow for 5G. This requires 1 ms network latency.
