In the world of computing and cloud services, the terms "control plane" and “data plane” are increasingly mentioned, even though these are actually older terms that originally came about in the networking world. This blog post aims to dive into the history of these concepts, where they are used and why, and how they’ve been extended into the emerging domain of SaaS. Let's dive in.

Software as a Service (SaaS) is a popular and convenient way of delivering applications over the internet, without requiring users to install or maintain them on their own devices. SaaS providers can offer scalable, secure, and cost-effective solutions to their customers, while also benefiting from faster development cycles and lower operational overhead.

Kubernetes is an open-source platform that enables SaaS providers to automate the deployment, scaling, and management of their applications across multiple clusters of servers. Kubernetes provides a consistent and reliable environment for running SaaS applications, regardless of the underlying infrastructure or cloud provider. Kubernetes also offers features such as service discovery, load balancing, health checks, configuration management, and security policies that simplify the development and operation of SaaS applications.
