Any application produced in one environment usually crashes or underperforms in other environments. Another difficulty with the physical servers is constant resource allocation, which becomes essential when several applications are hosted on a single server. There have been instances where one application occupies a large number of resources, causing other applications to struggle and eventually crash.
Virtualization, which allows several virtual machines to be hosted on a single CPU, is the most effective solution to this problem. One such way of doing so is containerization, which is currently adopted by most of the small and big companies. SInce Kubernetes and other container technologies are growing in popularity, the opportunities for professionals having expertise in the same are also increasing rapidly.
What is Kubernetes?
Kubernetes is an open-source container orchestration technology designed and developed by Google. It allows automation of the various processes involved in application development, namely deploying, managing, and scaling containerized applications.
Moreover, individuals can schedule and operate containers on clusters of physical or virtual machines, which makes Kubernetes ideal for cloud app development. The following are the main advantages of Kubernetes:
- It efficiently orchestrates containers over several hosts.
- It ensures optimal usage of hardware and resources.
- Increases the amount of storage available for running applications by distributing the resources equally.
- Uses container-based apps for scaling your solutions.
- Declaratively control services to ensure that deployed applications run in the desired way at all times.
- Auto-placement, auto-restart, auto replication, and autoscaling paradigms enable health-check and self-healing of apps.
The Need of Kubernetes
Managing containers effectively in a production environment is a must. Kubernetes is an open-source platform that aids in the effective administration of containers. It is a container-orchestration system for automating application deployment, scalability, and management. Moreover, Kubernetes provides a platform for resiliency in distributed systems. The following are the main features of Kubernetes:
- Deployments of containers.
- Autoscaling, service discovery, and load balancing.
- Persistent storage.
