The presentation discusses the use of Kubernetes namespaces and resource quotas for multi-tenancy and isolation of user groups and workloads. It also introduces the concept of owners and dependents in Kubernetes and provides an anecdote to illustrate the implementation of these concepts.
- Kubernetes namespaces serve for isolating groups of resources and can be used for separating and isolating distinct workloads and user groups
- There are two types of resources in Kubernetes: namespace scope and cluster-wide resources
- Resource quotas ensure that each distinct user group and namespace in a cluster gets its fair share of resources
- Owners and dependents are a well-known Kubernetes concept used for managing the relationship between resources
- An anecdote is provided to illustrate the implementation of these concepts, showing how a few lines of code can be used to bend Kubernetes rules and implement something that is disallowed
