Google Kubernetes Engine (GKE) | An Easy Guide

Google Kubernetes Engine, or GKE, is a powerful tool for managing containerized applications. It is a managed environment for deploying, managing and scaling containerized applications using Kubernetes, an open-source container orchestration system. GKE provides a platform to run and manage containerized applications on the Google Cloud Platform (GCP). This article will explore the details of Google Kubernetes Engine, its features, benefits, and how it works.

What Is Kubernetes?

Before diving into Google Kubernetes Engine, let’s first understand what Kubernetes is. Kubernetes is an open-source container orchestration system that automates containerized applications’ deployment, scaling, and management. It was initially developed by Google and later donated to the Cloud Native Computing Foundation (CNCF). Kubernetes provides a platform to manage containers across multiple hosts, providing features like load balancing, storage orchestration, automated rollouts, and more.

What is Google Kubernetes Engine (GKE)?

Google Kubernetes Engine is a fully managed environment for deploying, managing and scaling containerized applications on GCP. GKE provides a container runtime environment and orchestrates containerized applications’ deployment, scaling, and management. It also integrates with other GCP services like load balancing, logging, monitoring, and more.

Features of Google Kubernetes Engine (GKE)

• Automated provisioning and scaling – GKE automatically provisions the required infrastructure resources and scales them up or down based on the application’s workload.
• Multi-cluster management – GKE allows managing multiple clusters from a single interface, simplifying the management of large-scale applications.
• Integration with GCP services – GKE integrates with other GCP services like Load Balancing, Logging, Monitoring, and more.
• High availability – GKE provides high availability for containerized applications by automatically rescheduling failed containers and providing automatic horizontal scaling.
• Secure environment – GKE provides a secure environment for containerized applications with features like network isolation, access control, and automatic security updates.

How does Google Kubernetes Engine Work?

Google Kubernetes Engine uses Kubernetes to manage and orchestrate containerized applications’ deployment, scaling, and management. The following are the steps involved in deploying an application on GKE:

1. Create a container image of the application and store it in a container registry like Google Container Registry (GCR).
2. Create a Kubernetes deployment that specifies the desired state of the application, including the number of replicas, container image, and resource requirements.
3. Deploy the Kubernetes deployment to GKE, which creates the necessary infrastructure resources like virtual machines, load balancers, and network resources.
4. GKE automatically schedules the deployment on the available nodes and ensures that the desired state of the application is met.
5. GKE monitors the application and automatically scales the deployment based on the application’s workload.

Google Kubernetes Engine (GKE) Competitors

Google Kubernetes Engine (GKE) has become popular for businesses looking to easily manage and scale containerized applications. As with any technology, GKE has its competitors. In this section, we’ll explore the top alternatives to GKE and compare their features, benefits, and drawbacks to help you make an informed decision.

• Amazon Elastic Kubernetes Service (EKS) – Amazon Elastic Kubernetes Service (EKS) is one of the most popular AKS alternatives on the market. It’s a fully-managed Kubernetes service that runs on AWS and provides users with a secure, reliable, and scalable platform for container orchestration. Like AKS, EKS simplifies the process of deploying, managing, and scaling containerized applications. However, EKS is designed specifically for AWS users and may not be the best choice for those who use other cloud providers.
• Azure Kubernetes Service (AKS) – Azure Kubernetes Service (AKS) is another leading GKE competitor. It’s a managed Kubernetes service that runs on Microsoft Azure and provides users with a powerful and easy-to-use platform for container orchestration. AKS boasts many of the same features as GKE, including automatic scaling, self-healing, and efficient resource utilization. However, AKS is explicitly designed for Azure users and may not be the best choice for those who use other cloud providers.
• Red Hat OpenShift – Red Hat OpenShift is a powerful and flexible Kubernetes platform that provides users with a complete solution for building, deploying, and managing containerized applications. OpenShift is built on top of Kubernetes and adds many additional features, including an integrated container registry, CI/CD pipeline, and more. OpenShift is an excellent choice for enterprises that need a more robust and customizable solution than AKS.
• Docker Enterprise – Docker Enterprise is a comprehensive container platform that provides users with a complete solution for building, deploying, and managing containerized applications. It includes Docker Swarm, a native clustering and orchestration solution, and Kubernetes, which can be used as an alternative orchestration platform. Docker Enterprise is an excellent choice for businesses that already use Docker and want to consolidate their container-related workflows.
• Rancher – Rancher is a complete container management platform that provides users with a user-friendly interface for managing and deploying containers across multiple cloud providers. Rancher includes built-in Kubernetes and Docker Swarm support and is an excellent choice for businesses needing a more flexible and scalable solution than AKS.

Conclusion

Google Kubernetes Engine is a powerful tool for managing containerized applications on GCP. It provides a managed environment for deploying, scaling, and managing containerized applications using Kubernetes. With features like automated provisioning and scaling, multi-cluster management, integration with GCP services, high availability, and a secure environment, GKE simplifies the management of large-scale applications. If you are looking for a platform to manage your containerized applications, GKE is a great option to consider.
