Many businesses used to buy physical servers to host their applications and software. It faced many problems like server failure, the poor performance of software, and difficulty in allocating resources like RAM and CPU size. It led to many of them looking for ways how they can change this. Many opted for Kubernetes due to its low costs and proper utilization of resources. Kubernetes was different from the other cloud services as it used a better orchestration tool. According to the Cloud Native Computing Foundation (CNCF) 2020 yearly report, the number of people who use Kubernetes to host containers increased by 300%. The market is estimated to reach $4.3 billion by 2022, making the demand for Kubernetes experts rise. According to Payscale, the salary of individuals with these skills will be from $117k per year, increasing as time moves by. People who can work with Kubernetes include DevOps engineers, cloud engineers, Python developers, systems engineers, e.t.c. This guide will look at several types of Kubernetes certifications, what it entails, and their pricing.
