What is Kubernetes?

Kubernetes is an open source project that has become one of the most popular container orchestration tools around; it allows you to deploy and manage multi-container applications at scale. While in practice Kubernetes is most often used with Docker, the most popular containerization platform, it can also work with any container system that conforms to the Open Container Initiative (OCI) standards for container image formats and runtimes. And because Kubernetes is open source, with relatively few restrictions on how it can be used, it can be used freely by anyone who wants to run containers, most anywhere they want to run them—on-premises, in the public cloud, or both.

What is DevSecOps?

DevSecOps is integrating security into every part of the CICD pipeline from build to production. In DevSecOps, security is the shared responsibility of all stakeholders in the DevOps value chain. DevSecOps involves ongoing, flexible collaboration between development, release management (or operations), and security teams. In short, DevOps focuses on speed; DevSecOps helps maintain velocity without compromising security.

How DevOps and SRE are different?

DevOps stands for Development Operations, and SRE stands for Site Reliability Engineering. DevOps is an approach to managing software development processes that collaborates between operations teams and developers. Whereas Site Reliability Engineering (SRE) focuses on designing and implementing highly scalable, resilient, and dependable systems.

What exactly do DevOps do?

Under DevOps model, development and operations teams are no longer siloed. Sometimes, these two teams are merged into a single team where the engineers work across the entire application lifecycle, from development and test to deployment to operations, and develop a range of skills not limited to a single function.

What is DevOps in simple terms?

suman — Fri, 14 Jul 2023 06:17:55 +0000

DevOps is a cultural mindset where both key teams i.e. developers and operations agree that software is not really adding any value until it is used by somebody – customers, clients, employees, etc, due to this, both teams are ensuring together that software is delivered with speed and quality. Both groups will work as a single team on development and operation. This method will deliver applications and services faster than traditional software development processes.
