Containerization is a lightweight, portable, and efficient technology used in software development and deployment. It involves encapsulating an application and its dependencies into a self-contained unit called a container. Containers package an application, along with its code, runtime, libraries, and other necessary components, into a single executable unit. This unit is isolated from the underlying system and has everything needed to run the application, making it highly portable and easily deployable across different environments, whether they are on-premises or in the cloud.

Kubernetes or K8s is an open-source container orchestration platform designed to automate the deployment, scaling, and management of containerized applications. It provides a framework for efficiently organizing and coordinating microservices and containerized applications, ensuring seamless scaling, load balancing, and resource management across clusters of machines.

Although Kubernetes is made for accelerating deployment it still needs maintenance of the infrastructure and tools which implies a high level of cognitive load for developers. With a Managed Platform like Contain you can simplify the complexity of Kubernetes and cloud management.

Both services provide a managed environment for deploying, managing, and scaling containerized applications, but a Managed Application Platform abstracts away even more underlying infrastructure complexities compared to Managed Kubernetes. 

Managed Kubernetes requires users to manage certain aspects related to containers and the Kubernetes platform itself, while a Managed Application Platform like Contain is geared towards developers, allowing them to focus on code rather than infrastructure concerns.
