DevOps stands for development and operations, which is a set of various tools and technologies used to perform various business processes when combined. It helps in facilitating IT processes across all departments and streamlines communication and collaboration for better productivity.
Developing software or web application requires a complex process from conceptualization to deployment. It follows multiple intricate stages of development with multi-phase testing of a software or web application before being carried out into production.
Sometimes, it becomes a time-consuming software application development process due to some specific needs, major challenges, and business complexities. To make the software or application development process shorten, smoother, and faster, many developers are following a universal set of practices called the DevOps lifecycle.
In this article, we will cover everything about DevOps, its development lifecycle, tools, and much more? Let’s dive into the DevOps lifecycle and its uses in software development.
What is DevOps?
DevOps refer to development and operations, which is a combined software development methodology used to carry out various business processes together to bridge the gap between development and operational departments and facilitate communication across the organization. It covers exercising various tasks for application development in a professional manner.
To make it simple, the combination of software development and IT operations is called DevOps and the process to carry out several tasks of software or application development is called DevOps development lifecycle. DevOps methodology is a type of natural addition of Agile and continuous delivery approaches that makes software or application development faster using a unified continuous set of processes.
Implementing DevOps into your business can help gain competitive advantages that take your organization to the greater height of success with improved performance in a better working environment, quicker time to market with a continuous delivery model, and response to customers faster.
History Of DevOps
IT companies used to have two separate teams called Development Team and Operations Team before DevOps was introduced. Software developers working on software development used to write and test code several times to make sure it works perfectly or not. After that, the code was given for execution to the operational team to release and run the code. The operations team is used to check application performance, security, or any issues then report back to the development team about any bugs that exist.
As the process suggests, it may somewhat be causing conflict between the development and operations teams to acquire good results in a quicker time as both used to work separately. For example, if the developer wrote the code that works for the i5 processor, 16GB storage, and when the code comes to the operation team they are executing the same code for i3 and 8GB, they will make the code faulty even this could be a problem in their system environment or any missing library application.
To overcome this problem, DevOps was introduced to bridge the gap between developers and operations, allowing them to work together to express their ideas, concerns to get the best and desirable output in a minimum time. It was given rise to streamline development and operational processes to get continuous delivery of software or applications without any hassle.
To fix the problem, DevOps allows developers to summarize their code in a container which is a type of lightweight software environment. It contains all the necessary software summarized in it, which is required to run the code or application at its desired level.
When developer tested their code, they simply pass on this container along with the code to the operation team, so they can run the container along with the code for smooth functioning. That’s the DevOps history and how it was introduced.
How DevOps works? – The complete DevOps lifecycle
DevOps is an advanced software development methodology designed to remove all barriers between the development team and the operations team. In the DevOps model, both development and operations teams work together throughout the complete software application life cycle ranging from idea & conceptualization to development, testing, and deployment. DevOps helps to achieve high-quality products with quicker time to market and at significantly reduced costs.
The DevOps cycle involves planning, development, testing, deployment, release, and monitoring of the application, all while coordinating with different IT departments. The complete DevOps lifecycle includes the following seven stages:
1. Continuous Development
This is the first stage that includes planning and coding of the software development. The project vision is determined at the initial planning phase where developers start writing the code of the software application. DevOps uses several tools to maintain the code without requiring any tool for planning.
2. Continuous Integration
This phase is one of the most important phases of the entire DevOps lifecycle. This is the most used software development practice by developers in making frequent changes to the source code. The changes may happen daily or weekly depending on the situation. It involves frequent changes in the code, unit testing, code review, integration testing, and more to ensure that everything is up to the line. It includes the integration of updated code with the existing functionality to support and make them available for end-users.
3. Continuous Testing
Continuous testing is the stage where continuous testing of software or application is carried out for bugs. It uses powerful tools like TestNG, Selenium, JUnit, and more for continuous testing. QA testers utilize these tools to perfect multiple code-bases to ensure there’s no functionality break.
This phase uses Docker containers for simulating the test environment. It helps to save a lot of time and effort in testing with the help of automation.
4. Continuous Monitoring
As part of the DevOps process, monitoring involves all factors that contribute to the efficiency of the software, where information is tracked and carefully analyzed to discover trends and identify problem areas. In most cases, the monitoring comes with the integration of the operational capabilities of software applications.
It helps to solve various system errors, including server not reachable, low memory, high bandwidth usage, CPU, etc., enhancing security and availability of the service.
5. Continuous Feedback
This phase helps to improve application development by frequently analyzing results from the software operations.
This is a process where a developer gets constant feedback on the application and then explained its strengths and weakness to bring further improvements in the software application. It helps to make the application better, more efficient, and reliable with continuous feedback.
6. Continuous Deployment
This is the phase where developers deploy the code to the live server. It involves detail checking to make sure the code is perfectly used for each server. In this phase, new and updated code is continuously deployed to the server with configuration management tools like SaltStack, Puppet, Chef, etc. Various containerization tools are used in the deployment phase and help in bringing consistency across development, staging, testing, and production environment.
7. Continuous Operations
All DevOps operations help organizations to automate their IT operations and streamline workflows to build high-quality software or application with quicker time to market as they are based on continuity of automation.
In the discussion, it is evident that continuity is the key component of DevOps for eliminating all the steps that distract development, delay detecting issues, and ultimately result in a better product after a long time.
DevOps, allows developers to build any software or application that is more efficient, robust, and scalable and helps in increasing the productivity of your business with greater ROI.
What are the Benefits of DevOps?
DevOps provides numerous benefits to organizations, allowing them to produce high-grade software products with faster time to market and proven DevOps methodology combined with leading technologies. Developers working on DevOps get work faster, streamline quick responses, and facilitate communication across all IT departments. The top benefits of DevOps include:
High-quality product with faster time releases
DevOps helps to speed up product release time with the help of continuous delivery, allowing software developers to quickly solve the issues or fix the bugs in the early phases through continuous feedback of the applications. The team practicing DevOps can focus more on producing top-grade software products by automating all processes more efficiently.
Respond Faster to user needs
DevOps allows developers to quickly respond to change requests from user feedbacks, add or update new features, and customize existing functionality. It results in releasing software products with quicker time to market quickly and more efficiently.
Improved working environment
DevOps follows the best principles and practices which facilitate communication and collaboration across teams to improve productivity and agility of software development applications.
Developers working on DevOps are significantly proved to be more productive and experts in building quality software in less time. It allows development and operations teams to work together to acquire the best achievable products with good results.
Thus, DevOps is not only a set of practices but a philosophy that streamlines communication across the development and operational team. It mainly focuses on providing altering the way people work, so it doesn’t require constant code changes. The success of your DevOps application depends on how you adhere to DevOps principles and practices.
What are DevOps Tools and DevOps Toolchain?
DevOps Tools are the applications that automate the software development process to get desired product faster in the market. These tools help to focus more on facilitating collaboration and communication among software developers, operations professionals, and product management. It helps to eliminate context-switching, improve automation and the monitoring processes.
While DevOps toolchain contains tools and technology that allow both development and operations teams to communicate and collaborate across the whole DevOps software development lifecycle. It comprises DevOps fundamentals such as continuous delivery, continuous integration, continuous feedback, automation, and collaboration.
Which are the best DevOps practices?
Implementing DevOps practices can help streamline the software development process more efficiently. DevOps utilize the best practices that you should follow to optimize your development.
Build a collaborative culture: This is a proven DevOps practice used to improve collaboration and communication between development, operations, and other teams.
Use the right tools: DevOps uses the right tools to track performance metrics, display warnings when something goes wrong, or provide complete visibility into the software development progress.
Adopt CI/CD model: Continuous integration (CI) is the most used DevOps practice for integrating code changes from multiple developers into a central repository. Continuous delivery (CD) begins where continuous integration stops. DevOps uses continuous delivery to receive the code from continuous integration into the production environment.
Use Agile Development Management: DevOps uses the agile development approach which helps software developers to execute higher-quality products more quickly.
Monitor the right metrics: DevOps practices can help monitor the right metrics to detect when things go wrong so they can be recovered quickly.
Switches to microservices: Microservices are the best fit for the DevOps approach as they help in breaking large and complex projects into smaller pieces.
DevOps adoption: The DevOps culture, methods, and challenges
DevOps adoption allows organizations to significantly adopt DevOps capabilities, tools, and practices to improve the efficiency and productivity of your software product.
Development and operations work together to build software. DevOps culture describes their detailed understanding of each other’s work. It helps to improve transparency, streamline communication, and facilitate collaboration across development, IT operations, and other teams.
DevOps methods is a development methodology used to improve work during the entire software development lifecycle. The DevOps process can be visualized as an infinite loop that comprises various phases such as planning, coding, building, testing, releasing, deploying, operating, monitoring, and feedback of the software application.
Following are the major DevOps challenges that you often face:
- Switching to microservices from traditional infrastructure.
- Converting predefined processes to be more efficient ones.
- Integrating different tools for multiple domains.
- Lack of expertise in the industry.
- Individual tools set for Dev and Ops Team.
