One of the key features of containers is isolation. In this section, we'll establish a proper understanding of this powerful tool by looking at how a container achieves isolation and why this matters in the software development life cycle.
Understanding containers
Resource isolation
When an application launches, it consumes CPU time, occupies memory space, links to its dependent libraries, writes to the disk, transmits packets, and may access other devices as well. Everything it uses up is a kind of resource, which is shared by all the programs on the same host. To increase the efficiency of resource utilization, we may try to put as many applications as possible on a single machine. However, the complexity involved in...
