Kubernetes’ rise in popularity is due to its successful use cases in mission-critical sectors such as banking, edtech, and IT. By grouping the containers in this manner, Kubernetes eliminates the need to cram multiple functionalities in one single container. There can be one or multiple containers in a single Pod and each of them shares the same IP address and resources such as memory and storage. Kubernetes makes this possible by introducing Pods, or a collection of containers. However, it requires a proper system for integrating and orchestrating each of these smaller decomposed parts. Why do You Need Kubernetes?Ĭontainers decompose applications into smaller parts and enable faster development by assigning smaller, more focused teams responsible for specific containers. There is a dedicated container orchestrator which supervises these groups and ensures that they operate correctly. Containers running the same applications are usually grouped together into Pods. Kubernetes works as a “container orchestration system” that manages the lifecycle of containerized applications and automates the deployment of several containers. This is where Kubernetes comes to the rescue.įig: Traditional vs Virtualized vs Container Development ( source) However, you need to manage these containers in a proper way so that there is no downtime. It is a good way to bundle and run applications in a production environment.

A container is a small, lightweight virtual machine (VM) that does not have device drivers and shares its operating system among the applications.

How Does Kubernetes Work?īefore we dive into how Kubernetes works, you need to first understand what containers are and why people use them. Kubernetes eliminates the need for one infrastructure lock-in by allowing you to deploy cloud-native applications on containers without any restrictions and manage them exactly as you like anywhere you want. Traditionally, the performance of these applications is dependent on a particular infrastructure, such as adherence to cloud provider-specific constructs and back-end storage systems. What can you do with Kubernetes?ĭevelopers need to write applications that can run across multiple operating environments.

This means no more manual integration and configuration when you move from a testing environment to an actual production environment or from on-premise to the cloud! The Kubernetes logical compute environment offers common services to all the applications in the cluster as part of the ecosystem for the software to run consistently. The name Kubernetes is derived from a Greek term meaning ‘helmsman’ or ‘pilot.’ True to this word, Kubernetes provides the guiding force for developer platforms to transition from virtual machines (VMs) to containers and the statically scheduled to the dynamically scheduled. Open-sourced in 2014, Kubernetes is now a growing ecosystem that combines best practices for application deployment to run some of the largest software services by scale. It was initially built upon a decade and a half of the Google experience running production workloads. However, it operates at the container level rather than at the hardware level. It takes care of your scaling requirements, failover, deployment patterns, scaling, load balancing, logging, and monitoring, much like PaaS offerings. Kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services-with a framework to run distributed systems resiliently.

While the advent of DevOps has certainly automated and shortened the development-to-deployment lifecycle, the Kubernetes DevOps tool facilitates the configuration and automation process to get the best version of your software out there.

These are some questions every developer or application building enterprise asks.

When applications become larger and more complex, what is the most effective way to host and manage web applications and other dependencies? What if there is a need to scale out a service for business needs? How do we provide services across multiple machines without cumbersome network and storage settings?
