Tutorial Highlights

➤ Kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services—with a framework to run distributed systems resiliently. Kubernetes is also responsible for scaling requirements, failover, deployment patterns, scaling, load balancing, logging, and monitoring, much like PaaS offerings, and operates at the container level rather than at the hardware level.

➤ In this Kubernetes tutorial you’ll learn the benefits of using Kubernetes, differences between Docker Swarm and Kubernetes, various features like portability and framework support, and also learn how to install it on Ubuntu.

➤ So start learning now, understand the Kubernetes architecture, prepare yourself for a Kubernetes interview, and become an expert in the field of development.

Applications of Kubernetes

Kubernetes was primarily developed to solve deployment hassles for engineers working with technologies that use containerized solutions such as Docker. This Kubernetes tutorial covers the following key applications of Kubernetes used across the industry. 

1. Deploying Distributed Workloads

Kubernetes enables developers to deploy their applications in distributed environments by providing a controllable framework. They can connect the Kubernetes API for managing application workloads across multiple containers. This enables them to build a robust system that automates several server management processes.

It also reduces the system upkeep as Kubernetes features several DevOps processes in-built. Commonly, developers use this for deploying the following type of applications. 

  • Stateless Applications 
  • Batch Jobs
  • Stateful Applications
  • Daemons

2. Managing Containerized Applications

Applications that have complex dependencies usually present challenges while migration and execution of updates. With Kubernetes, this problem is solved as applications can be packed in container form. 

Kubernetes provides an interface for managing containerized applications so that the process of development to deployment can be made simpler. Therefore, it has a strong use case in the container DevOps that are harder to manage using other practices.

It comes with the following features for managing containerized applications.

  • Create and configure new containers 
  • Remove existing containers
  • Setup ports for multiple containers
  • Merge code from several containers into one 
  • Manage releases and rollbacks for containers 

3. DevOps Automation

Kubernetes finds significant application in the DevOps domain as it automates several processes associated with it. When applications are being deployed in distributed environments, it's hard to track each resource usage, actively manage infrastructure for all of them. 

But with Kubernetes, a majority of DevOps tasks are controlled automatically. Some of them are mentioned below. 

  • Automatic Resource Scheduling - By configuring the specific resource requirements of every application, Kubernetes automatically schedules the containers as per their resource usage. This allows the dynamic management of unused resources, leading to better resource utilization.
  • Automatic Health-Checks - Users can define automatic health checks that are used by Kubernetes to scan applications for discrepancies automatically. In case a fault is discovered, or a container crashes inadvertently, Kubernetes steps in to initiate repair protocols as well as notifying the system admin. 
  • Automatic Rollbacks and Releases - Kubernetes makes the tedious process of releasing application updates a lot easier by automating the release process. In case conflicts or health issues are found in releases, the rollback can also occur automatically. 

4. Deploying Hybrid Cloud Environments

Kubernetes has been developed with the vision to support the hybridization of cloud resources. This refers to creating a balanced system that utilizes Virtual Machines in alignment with containerized applications.

This hybrid system makes it easy for a business that relies genuinely on its legacy cloud to adopt Kubernetes easily. The process is called creating Heterogeneous Clusters that strike the perfect balance between containers and individual servers. 

In addition to that, Kubernetes also allows the utilization of resources from other public clouds such as AWS and Microsoft Azure. You can configure a workflow that uses AWS Elastic Block Storage for persistent storage in your solution.

Who Should Learn Kubernetes? 

Kubernetes primarily deals with server and system management. Hence, it is best suited for IT administrators and Cloud Engineers who want to foray into the role of Kubernetes Administrator. 

All kinds of Cloud Infrastructure Management professionals, may it be DevOps engineers or System Admins can benefit from learning Kubernetes. The quick adoption of the technology in enterprise IT signals that a firm career footing can be developed based on Kubernetes' skills. The Kubernetes tutorial covers all these things comprehensively. 


Some of the prerequisites on your path to learning Kubernetes will be a decent knowledge of how Docker and containers work. These systems are different from Virtual Machines and Virtual Private Servers, which are widely used in the industry. 

Other concepts such as Network Configuration and Linux will also come handy in grasping Kubernetes quickly but are not mandatory. Many cloud engineers with prior experience are enhancing their skills with Kubernetes.

1. What is Kubernetes?: Your Next Open Source Platform

Kubernetes is an open-source platform for managing containerized applications with several DevOps features. The platform enables cloud engineers to readily deploy their applications in distributed container clusters without having to worry about aspects like autoscaling or health checks. 

In this Kubernetes tutorial, you will learn about how Kubernetes came into existence and two of its widespread applications in the industry - DevOps and Container Orchestration. 

You will also learn about various Kubernetes features such as Resource Bin Packing and Secure Configuration Management. These features are critical to understanding how Kubernetes works. 

The Kubernetes tutorial covers the benefits of using Kubernetes over Virtual Machines and the added advantages that businesses can extract out of it. This includes everything from making applications highly scalable to increasing the speed at which applications are developed. You will be able to grasp an excellent theoretical overview of Kubernetes before jumping into the core concepts. If you're a beginner, this tutorial will teach you some of the essential prerequisites that will come in handy when you're setting up containers.

2. Understanding Kubernetes Architecture and Its Use Cases

Kubernetes uses a unique architecture to manage disparate systems. You will learn how this architecture operates alongside its components such as Pods, Nodes, Clusters, and the Master. These components interact with each other to lay down the framework in which services run. 

  • Need for using Kubernetes

    Get a primer on the fundamental problems that Kubernetes solves and the need for such a system to exist. The tutorial also reflects upon the concept of containers and how they relate to Kubernetes. 
  • Docker Swarm and Kubernetes

    Learn the key differences between a related technology called Docker Swarm, which is used in place of Kubernetes. This also includes why Kubernetes is actively replacing Docker Swarm in business applications.
  • Hardware Components

    Kubernetes employs the concept of Nodes, Clusters, and Persistent Volumes to develop distributed systems. You'll get an overview of what these hardware components mean and connect.

    Also, the tutorial touches upon Pods, Deployment, and Ingress that complete the basics of Kubernetes. Going ahead into running a Kubernetes deployment of your own, you'll need a fair understanding of these concepts. 
  • Industry Examples

    At last, learn how industry environments are using Kubernetes for their benefit. This gives a clear idea about the scope and actual implementation of Kubernetes. 

3. Kubernetes Interview Questions and Answers

Finally, after having covered the basic concepts and details about Kubernetes, the tutorial has the top 30 questions that are usually asked in interviews related to Kubernetes job profiles.
