Bulkhead pattern - Azure Architecture Center
The Bulkhead pattern is a type of application design that is tolerant of failure. In a bulkhead architecture, also known as cell-based architecture, elements of an application are isolated into pools so that if one fails, the others will continue to function. It's named after the sectioned partitions (bulkheads) of a ship's hull. If the hull of a ship is compromised, only the damaged section fills

Helm - The Kubernetes Package Manager
The package manager for KubernetesHelm is the best way to find, share, and use software built for Kubernetes. Helm helps you manage Kubernetes applications — Helm Charts help you define, install, and upgrade even the most complex Kubernetes application. Charts are easy to create, version, share, and publish — so start using Helm and stop the copy-and-paste. Helm is a graduated project in the CNCF

Deployments
A Deployment manages a set of Pods to run an application workload, usually one that doesn't maintain state. A Deployment provides declarative updates for Pods and ReplicaSets. You describe a desired state in a Deployment, and the Deployment Controller changes the actual state to the desired state at a controlled rate. You can define Deployments to create new ReplicaSets, or to remove existing Depl
