In today’s connected world, an organization has to maintain the right blend of time, efficiency and quality output with on-time delivery for a software application. These are critical components which measure the success and an organization's potential to withstand in the competitive market. Hence organizations continually strive to adopt DevOps and Agile for achieving best results within budget and stipulated time.
Unlike in the traditional waterfall methodology, starting from the requirements gathering phase till the maintenance phase, every stage has to be completed to move onto the next phase which delayed the development process, and the development team has to be idle till the design phase is completely done followed by testing which is time taking and less efficient. There exist several challenges in the traditional waterfall model or methodology which is rectified in DevOps.
Typically DevOps is not a tool or software; it is a culture that we can adapt to foster ongoing improvement. DevOps forms a channel to communicate and integrate between the developer and the operations team to enhance collaboration and productivity.
In DevOps, the development and testing phase of an application run parallely or go hand in hand, which reduces the friction.The developers and testers work as a team on the deliverables with direct communication, identifying, resolving issues and taking feedback is an ongoing process which significantly impacts the results.
DevOps is an approach and set of processes which brings the development and operations team together to achieve the assigned task. It fills the gaps which are found in the traditional software development approach (waterfall method) thus leaving more scope for improved efficiency, updating and delivering the application at a much faster pace. Hence DevOps is gaining more popularity.
DevOps symbol is an infinity loop which represents constant activity and improved efficiency. DevOps is all about achieving:
Continual Development- It’s a continuous process where the development process is divided into achievable tasks, it can be done in less time, and the application can be delivered on time. The developed code is created using various Automation tools and deployed to the testing team for testing.
Continual Testing - QA team use Automation tools such as Selenium, open source tools which have code reusability. Testing ensures that the application is free of errors which interrupts the functionality. Testing is done at each level and integrated with other components.
Continual Integration - Any enhancements in the functionality is integrated with the existing application during the integration stage. As testing and development is an ongoing process, integration is done to check if the integrated component does not disturb the flow of functionality of existing functionality. Also, any runtime errors occurred during integration are identified. Tools such as Jenkins are used to integrate which updates any changes in the code either through automation or manually.
Continual Deployment - When the software is deployed from development to the production environment, it ensures there are no production issues. Deployment uses Automation tools such as SaltStack, Puppet, etc. Deployment is important to check that the software application works fine in the production environment.
Continual Monitoring -There is constant monitoring for defects and resolving it at the earliest.
DevOps is not a tool or software; in fact, it’s a process or a mindset which is implemented to achieve better SDLC. DevOps cannot remove the differences arising in development and Operations team; it aims at bridging the gaps to achieve efficiency.
DevOps is about business agility and achieving improvement as an ongoing delivery process. It aligns a channel for better understanding of the development and operations team. Let's see some of the benefits of using DevOps.
In a situation where the development and operations teams are on different continents, the coordination is a hard task making it difficult to understand when an application is set to move to the operations phase. DevOps fosters better association between the development and operation teams. Shorter development cycles account to deliver results 60% faster than an application built using traditional software approaches.
Using DevOps the application is developed faster, but if the deployment fails, there is no use of how quick the application is developed. When software is built incorporating the DevOps principles, it’s easy to trace the defects thereby reducing the pre and post-deployment issues, with lesser rollbacks. It’s easy to fix the time to recover in DevOps environment than a traditional software approach. Also, rollbacks are much easier as only modules are impacted.
Using DevOps principles the development and operations team work more productively and are free of chaos. The teamwork is performance oriented rather than accomplishing individual goals thereby improving the software development process. There is more scope for exchanging ideas and innovation, and the teams can work for a common goal which is to move the product into the production environment. The KPIs have to be aligned accordingly.

Improved efficiency leads to better development with less scope of mistakes. Implementing DevOps principles we can automate DevOps tasks. As its continuous development process, the integration servers automate the testing code, therefore decreasing the manual efforts.
It helps to speed the development process and make it less prone to error. There are several methods to automate the DevOps tasks or deliverables. As DevOps is an ongoing development and testing process, it uses continuous integration servers which automate the testing process thereby lowering the number of manual efforts. Also, engineers can look into writing manually for winding up the tasks which cannot be done through automation.
All of the DevOps contribute to 60% faster development it reduces the costs considerably. When implementing DevOps principles, development teams need 35% fewer resources and 30% less IT costs.
DevOps is a culture, it involves a set of process frameworks and workflows, mainly through automation and feedback at the end of each cycle. Fortune 500 companies have incorporated DevOps principles and culture to achieve security, quicker delivery, build secure and robust applications. Its achieved through the ongoing delivery process as a part of delivering software security inline with the compliance policies, with security as a part of the infinite loop, receiving feedback and using it for enhancing the DevOp cycles. All accomplished using DevOps culture and incorporating security. Accomplish methods to deliver on time , maintaining security and minimizing risk factors in coordination and making it frictionless. Incorporate the feedback, measure, learn to achieve improvement.
