DevOps is past the skepticism stage and headed to peak adoption thanks to how well the masses are quenching curiosity, acquiring knowledge, and adopting popular development tools to facilitate production.
Trending DevOps tools like Kubernetes, Jenkins, Docker, Git, Maven, have taken off quite well. This explains why DevOps adoption is where it is today. However, it is not just the tools, DevOps practices are soon becoming the backbone of the IT industry.
DevOps As A Solution To The Demands Of Today’s Digital Market
Training and awareness aside, DevOps adoption is rising sharply because of market demands. As the software development market approaches maturity, there is an uncompromised demand for high-quality products that meet specific customer needs to be delivered within a short time, not to mention that demand for mobile-first applications is now at its peak.
Today, a well-designed app gives customers faster and better access to products, services, and information compared to the website. DevOps technology is at the center of it because it offers developers the tools and the environment to deliver and even exceed the demands of the market in this digital age and remain competitive in a very aggressive market.
The idea behind DevOps is that software development occurs faster and seamlessly when there is a synergy between software development and operations teams. Automation of processes, a key element in DevOps, is a result of the combination of Agile operations and Agile Systems which are the two principles that have not only led to increased quality service but also speedy deployments minus human errors.
The six approaches that that make DevOps processes uniques include:
- Continuous Development. It is a broad term that refers to the iterative approach in DevOps which encompasses continuous integration, testing, and deployment through the software development process.
- Continuous Integration (CI). A practice where developers integrate codes into a central repository for ease of configuration and testing.
- Continuous Testing. It helps to speed up the delivery of codes in the DevOps process. The idea is to perform testing early and frequently throughout the software development life cycle using automated systems to mitigate risk.
- Continuous Delivery. This process aims at ensuring continuous delivery and faster implementation of changes in requirements for the application development cycle. It ensures that codes are always ready to be deployed.
- Continuous Deployment. DevOps tools allow for the automated release of codes during production. For instance, use of containerization tools like Docker in combination with or alongside Kubernetes to facilitate ongoing deployment.
- Continuous Monitoring. DevOps provides for continuous monitoring of employed codes to see how well they are integrating into the infrastructure supporting them.
DevOps And The Cloud
Thanks to the emergence of the cloud platform, it’s now possible for organizations to access DevOps services from the cloud. The cloud offers users a platform on which the gap between IT development and the business community is bridged through increased agility. While the cloud offers access to low cost IT resources, DevOps tools make it possible to build high-quality applications fast.
With the right combination of tools, streamlining and automating some software development tasks should be possible hence achieving productivity. Tools like Git and Jira are used mostly during the planning phase of software development while others like Stash and GitHub have been designed for coding.
Docker, Kubernetes, and Jenkins are good for building and packaging codes for efficient deployment. The obvious benefits of these and other DevOps tools include operational flexibility and satisfaction of clients.
What Is Docker?
Docker is an open-source platform designed to make it easier for developers to build, deploy, and run applications in packages known as containers. Containers are units of a software in which developers package applications along with system libraries, configuration files, source codes, and all other dependencies needed for the containers to run in any environment.
The advantage of the containerization concept is that the software is separated from its environment which gives it an ability to operate at the same level in different computing environments. Therefore it should, for instance, run on Linux just the same way it would on Windows.
Containers are lightweight and easier to deploy and provision. Additionally with Docker,
- The container creation process is automatable and containers can be built automatically using the source code of the application in it.
- Container images can be reused to create other containers
- Developers have access to open-source container libraries
- Developers deploy applications fast
What Skills Do You Need To Be Good At Docker?
Docker’s popularity has continued to grow. Thanks to its portability and cloud-compatibility, Docker has become a cost-effective tool for both start-up and established software development businesses.
To make it even more viable and promote the containerization concept, Microsoft announced its partnership with Docker in 2016 during the Ignite conference in Atlanta. With every copy of Windows Server 2016, Microsoft would include CS Docker Engine at no extra cost.
This would see a sharp rise in demand for Docker skills which can be enhanced with the Docker certification. However, to be good at Docker, it is important to have already acquired the following skills.
- Fundamentals of Software development
- Basics of DevOps
- A good understanding of Linux Kernel
- Networking knowledge
- Working knowledge of Mac and Windows OSs
- Programming languages like Python
Is Docker A Marketable Skill?
Going by the statistics, Docker is the leading containerization tool. It was rated 1st in the most loved and 2nd in the most wanted platform. Its adoption has taken off quite sharply as developers look for a platform that favors fast and simplified development in a collaborative environment.
While there are several self-learning Docker resources on the internet, to build a solid foundation learning Docker skills. This way, you are not only acquiring knowledge but also putting your knowledge to the test.
