Most Frequently Used DevOps Tools in 2020

DevOps is generally illustrated as Development operation, which usually gives a link between a customer and company. It helps to increases a company’s ability to deliver applications and services quickly: evolving and improving products at a faster pace than the organization cannot achieve by using traditional software development and infrastructure management processes.

Therefore, it enables organizations to better service their customer’s requirement and compete more effectively in the market so that their product can become more secure and withstand every aspect of its customer’s requirement.

This concludes that DevOps is about getting changes to code and operations infrastructure into the hands of users faster. This focus on increasing release velocity means that developers and operations have to find new, safer, and more efficient ways to push changes into production. It provides speed, rapid delivery, reliability, scale which are essential while delivering a product to a customer.

Benefits DevOps

In a non-DevOps environment, such as waterfall development, the development process would start with the developers writing the code for the application. Next, a separate QA team tests the code to check if it meets quality requirements. If it does, the QA team releases the code into operations to deploy. Waterfall development is an approach that involves working in stages. In this approach, every stage depends on the outputs of the previous one. No doubt, this has prompted the learners into joining DevOps Training.

It actually took a while for technology to catch up and fully implement the principles and vision of DevOps.  There are DevOps tools which can be used for development operation purpose Kubernetes, Gradle, GitHub, Bamboo, Docker and many more comes into picture.

Kubernetes: Kubernetes is an open-source framework for "automating deployment, scaling, and management of containerized applications." Originally introduced by Google.

When Google started running containers a decade ago, nobody could reach this kind of infrastructure agility and efficiency. Using this knowledge, Google released Kubernetes as a free and open-source project. Nowadays Kubernetes is used by small companies and big enterprises who want to gain the efficiency and velocity Google has.

Kubernetes is an orchestrator for your containers that will create, schedule and manage your containers on a cluster of servers. Kubernetes can run on-premise or in the cloud, on a single machine or on thousands of machines. Thankfully, the open-source nature of Kubernetes is driving the development of managed Kubernetes solutions that ease the adoption of the platform.

Kubernetes is mostly used in large-scale organizations to perform critical tasks. Some of the Kubernetes features include:

• Automating manual processes—Kubernetes controls where the container is stored, and schedules container launches. 

• Self-healing—the platform constantly monitors the health of nodes, containers, and pods. If a pod or container crashes, Kubernetes replaces it by creating a new pod or container. 

• Horizontal scaling—Kubernetes allows teams to easily scale-out applications by adding more containers. 

• Storage orchestration—since it works with all major cloud providers, Kubernetes integrates easily with your chosen storage system.

• Automated rollout and rollback—This ensures that if anything goes wrong, Kubernetes can roll the application back with ease. 

• Run everywhere—Kubernetes is open-source. This characteristic helps you avoid vendor lock-in.  

• On-Demand Infrastructure This gives control to developers to get the resources they need, yet allows operations to control the configuration of the services. Kubernetes follows open service and API standards so you can expose cloud services.

• Environment consistency. Build once, and deploy into production-like environments everywhere. This gives you a consistent, production-like environment so it is the exact same whether you are on your local Windows or Mac development machine, a test server, etc. 

• Continuous Delivery pipeline. This is a series of automated steps to test code beforeit goes in production.  an automated process to prove to you a change is a bad change and it should not go into production

• A/B Testing: A/B testing delivers different versions to different customers so you can get real-world test results. Kubernetes manages routing traffic to different versions. The same version with slight modifications are possible.

Docker: Docker has been the number one container platform since its launch in 2013 and continues to improve. It’s also thought of as one of the most important DevOps tools out there.

It isolates applications into separate containers, so they become portable and more secure. Docker apps are also OS and platform-independent. You can use Docker containers instead of virtual machines such as VirtualBox.

Jenkins: Jenkins is the go-to DevOps automation tool for many software development teams. It’s an open-source CI/CD server that allows you to automate the different stages of your delivery pipeline. The main reason for Jenkins’ popularity is its huge plugin ecosystem. With Jenkins, you can iterate and deploy new code as quickly as possible. It also allows you to measure the success of each step of your pipeline. I’ve heard people complaining about Jenkins’ “ugly” and non-intuitive UI.

Bamboo: Bamboo is Atlassian’s CI/CD server solution that has many similar features to Jenkins. Both are popular DevOps tools that allow you to automate your delivery pipeline, from builds to deployment. 

Bamboo can save you a lot of configuration time. It also comes with a more intuitive UI with tooltips, auto-completion, and other handy features.

Git: Git is one of the most popular DevOps tools, widely used across the software industry. It’s a distributed SCM (source code management) tool, loved by remote teams and open source contributors. Git allows you to track the progress of your development work. You can save different versions of your source code and return to a previous version when necessary. It’s also great for experimenting, as you can create separate branches and merge new features only when they’re ready to go. To integrate Git with your DevOps workflow, you also need to host repositories where your team members can push their work. To integrate Git with your DevOps workflow, you also need to host repositories where your team members can push their work. Currently, the two best online Git repo hosting services are GitHub and Bitbucket.
