Kubernetes is required to automate and arrange tasks related to containers crucial to scaling your business. Here’s everything IT leaders need to know about Kubernetes, what it can do, its best practices, its key terms and more:
What is Kubernetes?
Kubernetes is an open-source, portable and extendable platform to manage containerized services, as well as workloads for facilitating automation and declarative arrangement. It is known to be a quickly growing ecosystem with widely available tools, services and support.
“Kubernetes” is a Greek word that stands for helmsman or pilot. In 2014, the first Kubernetes project was open-sourced by Google. Now, with more than 15 years of experience in handling production workloads, this platform combines the best of creative ideas with best practices from the community.
What is Kubernetes used for?
Many organizations require containers for managing various workloads. However, operational and provisional containers at scale, especially with microservices, are not suitable for any newbie. Particularly, essential apps (such as databases) that need a lot of planning, this organizational tool is very important.
Containers associated with Kubernetes are helpful for enterprises for managing their work in a better way while minimizing any risks. Businesses that use DevOps practices, including experimentation, iteration, short development sprints and experimentation, may need containers for the evolution process. It is also essential for improving the company’s microservices and cloud infrastructure.
What Kubernetes does?
This open-source cloud-native ecosystem is powerful for working along with the complementary projects revolving around Kubernetes. Therefore, it’s important to understand what this entire broader ecosystem can offer to IT companies.
It includes some essential services like monitoring tools like Prometheus, meshes like Istio, distributed tracing likes Kiali and Jaeger, inspection utilities like Skopeo, command-line tools like Podman, as well as enterprise registries like Quay. Selecting and integrating various tools for handling various business operations is a time-consuming process. But it’s the point when open-source platforms like Red Hat OpenShift are needed.
Kubernetes is also needed to ease the stress of managing, arranging, deploying and monitoring various containerized applications on a large scale. In several companies and businesses, the very first step to opt for Kubernetes to date is realizing the task for which you need this organizing tool. Sometimes basic containers in production need orchestration for managing everything well. But all you need to do is to accept that you need such a platform for managing workload and configuration of various operations in an organization.
Why you need Kubernetes and What it can do?
You need specific containers for running and managing your applications. For a production environment, you might have to manage certain containers for running applications and further ensuring no downtime. For example, in case a particular container is down or not working, another container must be ready to start. Wouldn’t things get better if this process is handled by an automated system? This is exactly what Kubernetes is needed for in an organization. Furthermore, you can make use of Docker, a platform that used OS-level virtualization for delivering software in containers.
Key Features of Kubernetes:
Given below are the key features of handling Kubernetes in organizations:
- Scalability: Kubernetes helps scale without putting the burden on the company’s operation team.
- Flexibility: Kubernetes also provides ample flexibility during the tasks and grows alongside to deliver you consistent applications – no matter how complicated your task is.
- Automation: It helps in putting containers automatically in place of their exact resource requirements. It even takes care of other constraints without compromising with availability. Furthermore, it provides the best effort for workloads for driving save resources and utilization.
- Self-Healing: Kubernetes even replace, restart and reschedule containers that are failing whenever their nodes die. It even kills contains that are not responding on time.
- Run Anywhere: Kubernetes also gives you proper freedom for enjoying the benefits of on-premises, public or hybrid cloud infrastructure, as well as enables you to move workloads effortlessly anywhere they are needed.
- Self-Discovery and Load Balancing: This system even provides containers with unique IP addresses, along with a single DNS (domain name server), load balance and name for different sets of containers.
- Automated Rollouts and Rollbacks: This system even rolls out progressively to make changes in your application or its overall configuration. Meanwhile, it monitors the health of your application for ensuring it won’t harm any process while working. If something goes unplanned, Kubernetes can automatically roll-back the unwanted change for you.
- Batch Execution: Besides replacing the failing containers, Kubernetes even manages your continuous integration workloads and batch execution, if desired.
What are the Business Benefits of Kubernetes?
Following are the key business benefits of Kubernetes:
- Kubernetes automates all the operational tasks for containers.
- It even provides a platform for running containers and scheduling them on a group of both physical and virtual machines.
- Arrange containers for multiple hosts.
- Completely depend and implement on container-based infrastructure within production departments.
- Check the health of your applications with auto-restart, auto-scaling and auto-replication.
- Scale containerized application, as required.
- Use hardware effectively for increasing the resources required for running your business apps.
Declaratively manage services to ensure that all deployed applications are working as you wish to deploy them.
Kubernetes offers businesses a complete framework for running distributed systems significantly. It even handles failover and scaling functions of an application while giving you an insight into deployment patterns. Therefore, businesses need this system to manage their operational tasks or workloads effectively.
