In Chapter 3, Working with Docker Images, we saw how Dockerfiles can be used to create images consisting of different services/software. Later, in Chapter 4, Network and Data Management for Containers, we saw how one Docker container can talk to the outside world with respect to data and network. In Chapter 5, Docker Use Cases, we looked into different use cases of Docker, and in Chapter 6, Docker APIs and SDKs, we looked at how to use remote APIs to connect to the remote Docker host.
Ease of use is all to the good, but before going into production, performance is one of the key aspects that is considered. In this chapter, we'll see performance-impacting Docker features and what approach we can follow to benchmark different subsystems. While doing performance evaluation, we need to compare Docker performance against the following:
- Bare metal
- Virtual machine ...
