Explore Containers certification and training courses — delivered live by certified instructors.
Containers are a technology for packaging applications with their dependencies into standardized, isolated units that run consistently across computing environments. Published by the Open Container Initiative (OCI) and widely implemented through tools like Docker and containerd, containers solve the problem of application portability by decoupling software from underlying infrastructure. They sit at the core of modern cloud-native development, enabling efficient use of system resources while supporting microservices architectures. Key components include Docker, used for building and running container images; containerd, a industry-standard container runtime that manages container execution, lifecycle, and image transfer; CRI-O, a lightweight runtime optimized for Kubernetes environments; and Podman, which enables daemonless container management. These tools support the Open Container Initiative (OCI) image and runtime specifications, ensuring interoperability across platforms and orchestrators like Kubernetes. Containers are for developers, DevOps engineers, and platform architects who need consistent, scalable, and resource-efficient application deployment across diverse environments. By isolating applications and their dependencies, containers eliminate environment-specific inconsistencies, streamline CI/CD workflows, and enable rapid scaling in cloud and on-premises infrastructures.
