What is DevOps?
The word DevOps is a combination of two terms; development and operations, intended to represent a collaborative or shared approach to the tasks performed by a business's application development and IT operations teams.
In simple language, DevOps is a philosophy that encourages better communication and collaboration between teams in an organization. It describes the adoption of iterative software development, automation and programmable infrastructure deployment and maintenance.
The term, DevOps, also covers culture changes, such as building trust and cohesion between developers and systems administrators and positioning technological projects to business requirements. DevOps have the power to change the software delivery chain, services, job roles, IT tools and best practices.
Why DevOps matter?
The latest software and the Internet have renovated the world and its industries, from shopping to entertainment to banking. Companies cooperate with their customers through software delivered as online services or applications and on all sorts of devices. They also use software to boost operational efficiencies by transforming every part of the value chain, such as logistics, communications, and operations.
How DevOps works?
Under a DevOps model, development and operations teams are no longer restricted. Sometimes, these two teams are joined into a single team where the engineers work across the entire application lifecycle, from development and test to deployment to operations, and develop a range of skills which are not limited to a single function.
In some DevOps models, quality assurance and security teams may also become more closely integrated with development and operations for throughout the application lifecycle. When security is the focus of everyone on a DevOps team, this is sometimes described to as DevSecOps.
The teams use practices to automate processes that previously have been manual and slow. They use a technology stack and tooling which help them operate and evolve applications much more quickly and reliably. These tools also help engineers independently accomplish tasks that normally would have required help from other teams, and this further increases a team’s velocity.
Benefits of DevOps
Speed
The DevOps model enables the developers and operations teams to achieve these results. For instance, microservices and continuous delivery let teams take ownership of services and then announce updates to them quicker.
Rapid Delivery
Increase the frequency and pace of releases so that one can innovate and improve your product faster. The quicker you can release new features and fix bugs, the faster you can respond to your clients’ needs and build competitive advantage.
Reliability
It is important to ensure the quality of application updates and infrastructure changes so you can reliably deliver at a more rapid pace while maintaining a positive experience for end users. Monitoring and logging practices help you stay informed about the performance in real-time.
Scale
Operate and manage your project infrastructure and development processes at scale. For instance, infrastructure as code helps you to manage your development, testing, and production environments in a repeatable and much more efficient manner.
Improved Collaboration
Developers and operations teams collaborate closely, share many responsibilities, and combine their workflows. This reduces inefficiencies and saves time thus benefiting the business.
Security
One can adopt a DevOps model without sacrificing security by using automated compliance policies, fine-grained controls, and configuration management techniques. For instance, using infrastructure as code and policy as code, one can easily define and then track compliance at scale.
