Containerization is the foundation of modern IT environments. It allows applications to run in lightweight, isolated containers that operate identically regardless of the infrastructure—local, cloud, or hybrid.
Solutions like Docker and standards from the Open Container Initiative (OCI) ensure full portability, security, and automation of deployment processes.

Containers support the DevOps and DevSecOps approach, allowing for rapid creation, testing, and updating of applications based on repeatable and secure images. With metadata and security scanning processes, the origin and quality of software can be tracked.

With the increase in deployment scale, the need for efficient orchestration has emerged - here Kubernetes plays a key role, an open-source platform that automates the running, scaling, and updating of services. It enables maintaining high availability, load balancing, and continuous deployment (rolling updates).

Modern organizations are increasingly combining Kubernetes with the GitOps approach, in which the code repository constitutes a single source of truth about configuration and environment status. This approach guarantees scalability, predictability, and full control over the application lifecycle.

Containerization and Kubernetes support software development:

• lightweight and portable – they work in any environment,

• secure and stable – with automatic monitoring and replication,

• efficient and modern – with full automation and cloud integration.

These technologies are behind the success of applications in multi-cloud and hybrid-cloud models today, providing companies with flexibility and independence from infrastructure providers.
