DevOps is the combination of cultural philosophies, practices, and tools that increase an organization's ability to deliver applications and services at high velocity: evolving and improving products faster than organizations using traditional software development and infrastructure management processes.
Building on top of DevOps, DevSecOps stands for development, security, and operations. It's an approach to culture, automation, and platform design that integrates security as a shared responsibility throughout the entire IT lifecycle.
Containers are a form of operating system virtualization. The purpose of a single container may be to run anything from a small microservice or software process to a more extensive application. Inside a container are all the necessary executables, binary code, libraries, and configuration files.
Microservices are small independent services that communicate over well-defined APIs. Building Microservices helps abstract implementation details from the whole organization while giving ownership to small, self-contained teams. The Microservices approach is more of an architectural and organizational strategy for software development.
​
If done right, the Microservices architecture helps applications scale and grow much more quickly than a monolithic architecture.
Kubernetes is a portable, extensible, open-source platform for managing containerized services that facilitates declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available.
OpenShift is a container orchestration platform based on Kubernetes that provides a number of additional features, such as a built-in image registry, networking and storage provisioning, and a web-based cons.
