Kubernetes and Docker are two of the most popular topics in cloud computing. As companies have moved to cloud computing, there has been a significant transformation. Forbes reports that 74% of Tech Chief Finance Officers (CFOs), believe cloud computing will have the greatest impact on their businesses in 2017.
There are many technologies that can help you use containers to manage your application. Cloud-based technologies have exploded in popularity as a way to build, deploy, manage, and maintain applications. Docker and Kubernetes are two of the most important terms in containerization. Docker is a computer program that uses containerization concepts. Kubernetes, on the other hand, is a complete container orchestration and management system.
Before we compare the most popular cloud computing concepts, let’s discuss what is kubernetes or docker.
What is Kubernetes?
Kubernetes was open-sourced by Google in 2014. It is widely used for container orchestration. Kubernetes can be used for general purposes and is a great competitor to virtual machines. Kubernetes, or Kube, makes it easy for developers to automate, scale up, and manage container-based workloads within live production environments.
Kubernetes can be scaled up and down according to the needs at any given time. Kubernetes’ core architectural elements are:
Nodes
Clusters
Containers
Pods
Deployments
Services
APIs
Masters
Kubectl
Below are some key features that Kubernetes can use to maintain containerized applications.
Service discovery
Automated application deployment
Storage administration
Auto repair and self-healing
Monitoring the container’s health
Balance the data volumes
Configuration management

What are Kubernetes’ strengths?
Kubernetes can be used to ensure that your application runs in the way it was intended. Kubernetes will check whether all containers are up and running. It will also help the application self-healing. A container that is not responding would be replaced by a new one.
Kubernetes can be used to scale up horizontally. Kubernetes will create new containers to handle the CPU-intensive parts if there are too many loads. It can reduce downtime and make deployments easier. Kubernetes allows you to run an existing version of your application while you deploy the new version. Your app users won’t notice any downtime since the older version will continue to run until the new version is properly started.
Kubernetes can perform many functions. This
