👨‍💻 What does DevOps entail? Who should consider acquiring DevOps skills and what are the reasons behind it? What can be expected in the future of DevOps?

DevOps is a way of working in software development where the development team and the operations team work together closely. It's like a bridge between the people who create the software and the people who make sure it runs smoothly. In traditional software development, the development team writes the code and hands it over to the operations team, who take care of deploying it and managing the infrastructure. This can lead to problems because the two teams often have different goals and ways of working.

DevOps aims to solve these problems by promoting collaboration and communication between the development and operations teams. It encourages them to work together from the beginning of the software development process until the end. This means that developers and operations people need to understand each other's work and support each other. By working together, they can automate processes, use tools that help them work more efficiently, and create a culture of shared responsibility. This helps to deliver software faster, with fewer errors, and makes it easier to respond to changes and fix problems quickly.

In simple terms, DevOps is about breaking down barriers between developers and operations teams, working together, and using automation and collaboration to make software development and deployment faster, smoother, and more reliable.
