▶ What is DevOps?
It is a combination of Development and Operations. DevOps is a practice that allows a single team to manage the entire application development life cycle: development, testing, deployment, and monitoring.
The top goal of this methodology is to reduce the duration of the system’s development life cycle while delivering features, fixes, and updates frequently in close synchronization with business objectives.
DevOps was created to lower update failure rates, shorten recovery or remediation times, and promote faster releases.
In simple words, DevOps can be defined as an alignment of development and IT operations with better communication and collaboration.
▶Why is DevOps Needed?
DevOps embraces agility and problem-solving. Collaboration is central. Having this mindset encourages broader communication instead of sticking strictly to one discipline.
It takes the right technology, situational assessment, and attitude to pull off successful software development and delivery.
Collaboration, communication, and integration are the key elements of incorporating DevOps into any development and delivery setting. Building multi-skilled teams that are made up of individual talents (e.g., developers, sysadmins, and testers) can add great benefit, but without the right teamwork and attitude, the talent is virtually useless.
DevOps is also designed to propel business innovation and the drive for continuous process improvement.
▶What are the Business benefits of DevOps use?
It allows for implementing Continuous Integration/Continuous Delivery(CI/CD), which helps launch products faster into the market.
Other important reasons are:
▶DevOps top principles
These are the six principles that are essential when you are thinking about adopting DevOps:
1. Customer-Centric Action: The DevOps team must constantly take customer-centric action to invest in products and services.
2. End-To-End Responsibility: The DevOps team needs to provide performance support until they become end-of-life. This enhances the level of responsibility and the quality of the products engineered.
3. Continuous Improvement: DevOps culture focuses on continuous improvement to minimize waste, and it continuously speeds up the improvement of products or services offered.
4. Automate everything: Automation is a vital principle of the DevOps process, and this is not only for software development but also for the entire infrastructure landscape.
5. Work as one team: In the DevOps culture, the designer, developer, and tester are already defined, and all they need to do is work as one team with complete collaboration.
6. Monitor and test everything: Monitor and test everything: The DevOps team needs robust monitoring and testing procedures.
▶Who is a DevOps Engineer?
DevOps Engineer is an IT professional who works with software developers, system operators, and other production IT staff to administer code releases.
DevOps should have hard and soft skills to communicate and collaborate with development, testing, and operations teams.
▶DevOps most used toolchain
DevOps toolchain is a collection of tools, often from a variety of vendors, that operate as an integrated unit to design, build, test, manage, measure, and operate software and systems. It enables the development and operations teams to collaborate across the entire product lifecycle and tackles key DevOps fundamentals including continuous integration, continuous delivery, automation, and collaboration.
There are two primary approaches to a DevOps toolchain: an all-in-one or an open toolchain. An all-in-one DevOps solution provides a complete solution that usually doesn’t integrate with other third-party tools. An open toolchain can be customized for a team’s needs with different tools.
