With the advancement of technology, the world has been coming right into the fist of our palms. Container management is the future of cloud-based computing systems. Container management has been immensely facilitating cloud-based computing, especially with the help of Kubernetes. The word Kubernetes originated from the Greek word, Kuber meaning "pilot." Kubernetes or K8s helps automate container management's operational tasks, including deploying applications via built-in commands. It uses orchestration or clusters, or bundling in computer applications. Kubernetes helps in rolling out changes and scaling applications as per the needs. It also helps to monitor computer applications and makes them manageable.
However, with the development of software and technology, new Kubernetes alternatives exist in the world of computing. Let us read about the K8s alternatives, Kubernetes competitors, and how they can perform the tasks with utmost precision like that of Kubernetes.
What is Kubernetes and Why Seek an Alternative?
Kubernetes is the future of cloud-based computing systems in container management. Kubernetes is a container orchestration tool developed by Google to perform a complete containerized application lifecycle. There are plenty of benefits to choosing Kubernetes. They provide high availability, scalability as well as precise predictability in containerized applications.
Kubernetes is an optimal open-source container orchestration tool that can monopolize the market and assert its dominance. It needs alternatives to have a competitive market, and a contrasting comparison could be drawn between the other players emerging in the market. Furthermore, it also helps to understand the needs of the enterprise for the proper orchestration tool needed as per the strength of the enterprise. Kubernetes being the only available open source, might create a clash between the different aspects of market needs.
Currently, Kubernetes does not contain its monopoly in the market. Other Kubernetes competitors have asserted their dominance in the market. These alternatives have made it easier for the enterprise to choose a container orchestration tool specified for their needs.

Google Kubernetes Engine helps in orchestrating and automating software development with scaling and management. It was released in 2014 and has been one of the most popular container orchestration tools after Kubernetes. It is a fine example of automating software deployment rather than K8. It is a simple Kubernetes alternative and can benefit industries that have a bigger budget in container management.
2. Amazon Elastic Kubernetes Services (EKS)
Amazon Kubernetes services are open-source software that allows the deployment and management of containers in clusters. It is very efficient in computing instances for deployment, scaling, and maintenance. There is no need to install, operate or maintain any kind of plane or nodes for Kubernetes to operate freely. It is a hassle-free way of container management that does not overwhelm the control plane or nodes.
3. Azure Kubernetes Services
Azure Kubernetes Services is one of the quickest ways to start developing and deploying cloud-native apps that help build code to cloud pipelines and guidelines. This particular container of K8 alternative is one of the primal competitors in the whole market. It helps in getting unified management with edge and multi-cloud Kubernetes clusters. It is a very powerful open-source container terming it to be one of the biggest competitors of Kubernetes providing a simpler alternative to Kubernetes. It is used mainly in small-scale and large-scale industries to save time.
Kubernetes Alternatives: PaaS Platforms
