What most people don’t realize is that much of this isolation can be removed to complete various systems administration tasks.ĭevelopers and systems administrators have different concerns. I often say that containers can be viewed as “fancy processes” that typically run in their own user space, with extra isolation added. Application containers are what developers are trying to move into production or onto a cluster to meet the needs of the business. As we will see, each requires more or less deterministic communication with, as well as, secure access to the underlying container host.Īpplication containers (aka service containers) provide tooling for applications and batch processing - examples include: web servers with Python or Ruby, JVMs, or even Hadoop or HPC tooling. Super Privileged Containersīefore we start, let’s delineate between two main types of "container workloads" - application containers and Super Privileged Containers (SPCs). While there are many ways for a given container architecture to affect and/or influence your application, the user space provides tooling that is often overlooked, namelyĪpplication Containers vs. In today’s post we will highlight a handful of important ways the choice of the user space can affect application deployment and maintenance. In Architecting Containers Part 2 we explored why the user space matters to developers, administrators, and architects. In Architecting Containers Part 1 we explored the difference between the user space and kernel space. ![]()
