Navigating the CNCF Cloud Native Landscape: A Map to Uncharted Terrain
The CNCF Landscape is divided into various categories, each representing different aspects of the cloud native environment. These include:
1. Orchestration & Management: Tools like Kubernetes (the star of the show) fall into this category. They help manage containerized applications across clusters of machines.
2. Runtime: Here you'll find container runtimes like containerd and CRI-O, which are responsible for running the containers.
3. Provisioning: This includes infrastructure provisioning tools like Terraform and Pulumi, which help automate the setup of your cloud infrastructure.
4. App Definition & Development: This category includes frameworks and tools like Helm and Kustomize that aid in defining and managing application configurations.
5. Observability & Analysis: Tools like Prometheus and Grafana help monitor and analyze the performance of your cloud native applications.
6. Security & Compliance: Projects like Open Policy Agent (OPA) and Falco ensure your applications are secure and compliant with regulations.
7. Networking: Service meshes like Istio and Linkerd, as well as network plugins like Cilium, fall under this category, helping manage network traffic within your cluster.
8. Storage: Tools like Rook and OpenEBS manage persistent storage for your containerized applications.
The CNCF Projects represent a particularly well-traveled path to deploying a cloud native application. These projects are open source and are hosted by the CNCF, ensuring a high level of community support and adoption. Examples include Kubernetes, Prometheus, Envoy, and many more.
Now, here's where the fun (and sometimes the confusion) begins. The CNCF Landscape includes a dizzying array of technologies, some of which you might have never heard of or used. It's a crazy set of tools, and it's a wonder we have any knowledge in this space at all!
A Joke to Lighten the Load
