What Is DevOps?
DevOps is where software development meets IT operations. DevOps engineers are masters at ensuring continuous high software quality delivery and shortening the systems development cycle. DevOps goes hand-in-hand with Agile development.
DevOps can be visualized as a workflow that emphasizes communication between IT professionals and software engineers in a production environment. DevOps focuses on automating infrastructure changes and software deployment.
Continuous deployment is at the core of all DevOps functions, continuously integrating development and operations into a streamlined process. This way, turnover time is reduced, and companies can rapidly deliver software updates and security measures internally and externally.
What Does a DevOps Engineer Do?
DevOps engineers apply their technical expertise to create cloud-based solutions at scale. They also guide customers through transformational business solutions by combining philosophies, tools, and practices, that deliver end-to-end applications and infrastructure solutions. DevOps engineers are expected to have technical depth and hands-on implementation experience tools and practices in the DevOps toolchain. A DevOps Engineer should be able to design and code modules for applications, infrastructure, and processes.
DevOps engineers are also responsible for developing operations that balance service reliability and delivery speed efficiently. They must be skilled at using cloud platforms to deploy and monitor services, build software delivery pipelines, and manage incidents. Senior DevOps engineers are expected to take on more responsibility. They are also expected to work independently with minimal supervision.
Here are some key roles and responsibilities of a DevOps Engineer:
- Working with partners, customer technical leads, and client executives to manage and deliver implementations of DevOps solutions.
- Working with product and engineering teams to package best practices and lessons learned into thought methodologies, leadership, and published assets.
- Interacting with partners and technical stakeholders to manage project scope, deliverables, priorities, risks/issues, and timelines.
- Advocating for customers needs to overcome adoption blockers and drive the development of new features based on field experience.
- Proposing solution architectures and managing deployment of distributed virtualized infrastructure solutions following customer requirements and implementation best practices.
Types of DevOps Engineers
Based on their function and skills, DevOps engineers can be categorized as:
- DevOps Evangelists: They are responsible for the implementation of end-to-end DevOps strategies in product development.
