Motivation Containers provide OS-level virtualization for running applications on same kernel as host with less overhead, faster startup and smaller sizes than VMs. Containers are well suited for microservices-based applications which are composed of several independent services running in a coordinated manner. Cloud Container Compute gives you the ability to deploy and scale Docker containers on-demand using Kubernetes technology. The service provides with easy provision of Kubernetes clusters on EGI Cloud Compute resources that can be scaled and upgraded without the overhead of installing, managing and operating the nodes. Cloud Container Compute offers users offers guaranteed computational resources in a secure and isolated environment with industry-standard Kubernetes container orchestration platform that: - Manages the nodes where to run the containers - Automates the deployment, management, scaling, networking, and availability of container-based applications running on that cluster. 12/29/2021 3
