Launched in 2015, Kubernetes was originally designed by Google. Later, Google entered into a partnership with Linux Foundation to form the Cloud Native Computing Foundation. Now Kubernetes is maintained by the Cloud Native Computing Foundation.
Kubernetes (also known as k8s or “Kube”) is an open-source container orchestration platform that automates many of the manual processes involved in deploying, managing, and scaling containerized applications.
What is a container?
Containers are units of software that package applications and their dependencies in isolation from their environment. They are independent executable pieces of code that contain the dependencies required by an application. They share the host kernel with other containers and applications running on the host. This means that instead of each container needing its own operating system (OS), the containers instead use the operating system of the underlying host, requiring significantly fewer resources.
What Are Containerization Of Apps
Containerization is an approach to software development in which an application or service, its dependencies, and its configuration (abstracted as deployment manifest files) are packaged together as a container image. The containerized application can be tested as a unit and deployed as a container image instance to the host operating system (OS).
Careers For Kubernetes Developers
With the growth of cloud platforms, the Container Apps development market has also seen visible growth. Having a solid relationship with Google and Linux, Kubernetes has become a very widely recognized platform in this market segment.
After 2016 there has been a steady growth in Kubernetes-oriented jobs.
In a Cloud Native Computing Foundation survey, it was that 83% of tech professionals cited Kubernetes as their top choice for container management. Kubernetes even gained support from Docker, Microsoft, RedHat, and IBM, contributing to its popularity, the survey suggests.
Kubernetes has gained a footprint in the enterprise world to the point where organizations want employees familiarized with the tool. In the last few years, Kubernetes has become an in-demand skill and has gained popularity with both employers and job seekers.
Due to the growth in the job market, the professionals have also gathered a lot of interest in learning Kubernetes related skills. Nowadays Kubernetes certifications have also become very popular with the development professionals.
IBM, VMWare, Microsoft, Verizon, and Cisco are among the few major employers with openings for Kubernetes professionals. Due to Kubernetes’ availability on most of the major cloud platforms, it has become a highly recognized professional career.
Job Roles For Kubernetes Professionals
Following are the most common job roles for Kubernetes professionals;
Kubernetes Professionals – Average Salary
As per 2020 statistics, the national average salary for Kubernetes jobs in the US is $147,732. Depending upon the location, job nature, job level, employer type, and experience, it can range from $70,500 to as high as $219,000.
Certified Kubernetes Application Developer – Certification Overview
The Certified Kubernetes Application Developer (CKAD) exam certifies that users can design, build, configure, and expose cloud-native applications for Kubernetes.
Who Is It For
This certification is for Kubernetes engineers, cloud engineers, and other IT professionals responsible for building, deploying, and configuring cloud-native applications with Kubernetes.
About This Certification
CKAD has been developed by The Linux Foundation and the Cloud Native Computing Foundation (CNCF), to help expand the Kubernetes ecosystem through standardized training and certification. This exam is an online, proctored, performance-based test that consists of a set of performance-based tasks (problems) to be solved in a command line.
What It Demonstrates
The Certified Kubernetes Application Developer can design, build, configure, and expose cloud-native applications for Kubernetes. A CKAD can define application resources and use core primitives to build, monitor, and troubleshoot scalable applications & tools in Kubernetes.
The exam assumes knowledge of but does not test for, container runtimes and microservice architecture.
The successful candidate will be comfortable using:
– An OCI-Compliant Container Runtime, such as Docker or rkt.
– Cloud-Native application concepts and architectures.
– A Programming language, such as Python, Node.js, Go, or Java.
