At the heart of DevOps, there is one true goal - not just to offer better applications but to offer them as soon as possible to the users. Development and Operations, shortened to DevOps, refers to the system or philosophy of framework that applies quicker and more efficient processes to facilitate better software development and speed up the release of the same.
While DevOps sounds like a simple process, it actually contains multiple complex processes and steps carried out by expert technicians. Because of its functionality, the framework of DevOps offers a wide array of crucial benefits to organizations as well as end-users.
DevOps - A Quick Introduction
In simple terms, DevOps can be understood as a set of tools and principles that combine the processes of the software development team and the IT team. The integration led to the rise of a new set of practices that makes software development, testing, and deployment more efficient and quick. Although DevOps has been popular in the past decade, its history dates even far back, to the early 2000s.
The primary goal of DevOps is to combine the knowledge and processes of different professionals from varying fields that will enhance the lifecycle of software. Not only is DevOps a new way of approaching software development and deployment, but it is also a cultural shift in the software industry. Several tools are used to automate processes in DevOps, leading to better reliability and shorter process time.
Top 8 Benefits of DevOps
DevOps is more than focusing on benefits for enhancing software development - it offers other advantages, like improving security and enabling cross-team collaborations. Here are the top 8 benefits of DevOps.
Simplifying Software Development
The main motive of DevOps culture is to simplify the processes involved in software development and deployment. This is done through multiple steps like streamlined collaboration, automated testing, and quick feedback. DevOps focuses on the Infrastructure as Code (IaC) approach - by adopting this method, development, testing, and production processes gain improved consistency.
DevOps practices also involve automation processes that reduce manual loops and bring down the number of errors. Automated testing ensures bugs are identified and fixed immediately, thus enhancing the efficiency of the overall process.
Improved Speed and Stability
DevOps practices involve continuous integration and continuous delivery (CI/CD) practices - this is done to automate code changes into the pipeline and improve the speed of the process. Not only does this automate changes in the code, but it also helps in tasks such as building and deploying applications. Since the processes are automated, they do not leave any room for error. At the same time, the entire process is also sped up to promise quick delivery and deployment.
Efficient Team Collaboration
The traditional processes involved in developing and testing software included the work of a variety of professionals from different technical teams. This sequence also involved a set pattern of tasks that were followed in a particular order.
However, in DevOps, two or more teams collaborate efficiently to simplify the practices and cut down the processing time. The operations and development teams work together instead of operating on different levels. This means that more work is done simultaneously, hence leading to a better understanding between the teams on how the product is developed and tested.
Prioritizing Automation
Automated tools serve as the crucial factor that upholds DevOps. It is through automated processes that integrating code and deploying applications happen. The main advantages of automating these processes are one, they save time by speeding up the cycle, and two, automation leaves no room for manual errors.
Notably, automation tools pave the way to more creative solutions. Professionals figure out more efficient means through which testing and deployment are automated. This empowers both the technician and the automating process.
Better Customer Focus
The primary goal of DevOps and software development is to give users what they want. With DevOps focusing more on improved speed and stability, customer focus becomes easier. The efficient collaboration in DevOps methodology ensures that the developed applications are tested and deployed in a matter of weeks. Continuous feedback is also a great advantage in DevOps, thus informing the teams of the bugs and errors that need to be fixed.
Reduced Production Costs
One of the main reasons why organizations migrate towards DevOps culture is that it reduces production and processing costs. Since multiple teams collaborate to ensure the development and deploying applications efficiently, faster updates are released. Organizations save on human resources, but they also reduce costs as DevOps methodologies can enhance the deployment of applications more quickly and efficiently, thus making software more affordable.
Offers Flexibility
DevOps methodologies offer flexibility in two important ways - one, it enables developers to work flexibly hand-in-hand with other professionals in the team; two, it promises organizational flexibility, thus ensuring that the teams work and collaborate better with each other.
With increased flexibility, developers get their own space to try and test better practices that can enhance the deployment process. As for organizational flexibility, it gives the company a competitive edge, encouraging internal teams to join hands and integrate processes that benefit both the organization and the user.
Enhanced Security
Security is the core concern of any organization involved in software development and deployment, and this concern is addressed effectively through DevOps practices. Primarily, security practices can be integrated into the entire development process of an application. Additionally, automated tools and the constant review of code ensure that any bug or error found in the process is immediately addressed and resolved. The usage of advanced tools for monitoring the development process ensures that security is the top requirement in the process.
