DevOps

DevOps is the combination of Development (Dev) and Operations (Ops), it is an organizational approach that allows swifter development of applications and smooth maintenance of current deployments. DevOps is not a technology in essence, but it takes into consideration everything from the organization to culture, processes, and procedure.

DevOps has its own way of functioning, 
A DevOps team consists of developers and IT operations personnel that collaborate throughout the product lifecycle to improve software deployment speed and quality. It is a new way of working, a cultural transformation, with far-reaching implications for teams and the businesses for which they work. 

Development and operations teams are no longer silos in a DevOps architecture. These two teams merge to form a single team with engineers who work across the whole application lifecycle from development and testing to deployment and operations and possess a diverse set of abilities. DevOps teams employ tools to automate and speed up procedures, which improves reliability. A DevOps toolchain aids teams in tackling key DevOps principles such as continuous integration & delivery, automation, and collaboration.

Faster and easier releases, increased team productivity, increased security, higher quality products, are all benefits of DevOps. To list them out: 
Speed - DevOps teams produce higher-quality, more consistent products more frequently. Using automated technologies, teams may create, evaluate, and distribute software. 
Improved Collaboration- The foundation of DevOps is a culture of collaboration between developers and operations teams that share responsibility and integrate work. This makes the team more efficient, saves time and allows you to code designed for the environment in which the team operates. 
Rapid Deployment- By increasing the frequency and speed of releases, the DevOps team can quickly improve their products and can gain a competitive advantage by releasing new features quickly and fixing the bugs. 
Quality and reliability- Practices such as continuous integration and continuous delivery ensure that changes are functional and secure, and improve the quality of the software products.

However nothing comes without challenges, 
Teams rooted in traditional work practices can struggle or resist revising the team structure to adopt DevOps practices. Some teams may mistakenly believe that the new tools are sufficient to deploy DevOps. However, DevOps is a combination of people, tools, and culture. Everyone on the DevOps team needs to understand the entire value stream, from brainstorming to development to the end-user experience. The silos must be disassembled to work together throughout the product life cycle.

The future of DevOps will bring for sure changes in operations and organizational strategies, but its primary mission will remain the same. Organizations will need to realize that DevOps is all about the process and that the organization's DevOps-related goals and expectations will evolve over time.
DevOps brings together development and operations, redefining the organizational structure, practices, and culture to enable rapid, agile development of software and scalable, reliable operations and these practices in turn optimize customer experience.
