Containers as a Service (CaaS) is a cloud service model that provides a platform for managing and deploying containerized applications. CaaS allows developers and IT teams to upload, organize, run, scale, and manage containers using an underlying cloud infrastructure. It provides tools for container orchestration, such as Docker and Kubernetes, which handle tasks like deployment, scaling, and load balancing. CaaS offers flexibility, scalability, and ease of management, enabling organizations to deploy applications quickly and efficiently without worrying about the underlying infrastructure. This service simplifies the development and operations process, enhances application portability, and improves resource utilization.
