DevOps Tutorial for Beginners
DevOps is a cultural and technical approach to software development that emphasizes collaboration and communication between software developers and operations professionals. It aims to streamline the software delivery process and improve software releases’ speed, quality, and reliability.
DevOps practices aim to automate many software development and delivery aspects, including infrastructure provisioning, code deployment, and testing. This allows teams to iterate and release new features and bug fixes more quickly and confidently.
Critical elements of DevOps include continuous integration and continuous delivery (CI/CD), infrastructure as code (IAC), and monitoring and observability. DevOps also promotes using agile development methodologies, such as Scrum and Kanban, emphasizing the importance of feedback and team collaboration.
The adoption of DevOps has resulted in faster time-to-market, higher software quality, and improved collaboration and communication between teams. However, implementing DevOps can be challenging and requires significant investment in tools, processes, and culture change.
This DevOps Tutorial for Beginners will help you learn DevOps concepts and tools with examples and demos. You will understand how a DevOps pipeline can be imagined for existing infrastructure. Furthermore, it will cover different DevOps tools & phases.
