There is no orthodox career course for a DevOps engineer. IT professional developer or system administrator can expand the responsibilities towards ingenious progressive evolution of DevOps.
Key responsibilities of DevOps engineer are:
- Administration of IT infrastructure
- Choosing the right deployment models
- Conducting the testing protocol and critical monitoring
Before we know more we have to know what is DevOps?
DevOps is a new term emerging from the collision of two major related trends. The first was also called “agile infrastructure” or “agile operations”; it sprang from applying Agile and Lean approaches to operations work. The second is a much expanded understanding of the value of collaboration between development and operations staff throughout all stages of the development lifecycle when creating and operating a service. DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). It is a combination of practices and tools designed to increase an organization’s ability to deliver applications and services faster than traditional software development processes. This speed enables organizations to better serve their customers and compete more effectively in the market.
Getting started with DevOps
DevOps initiatives have been originated from dev teams and from ops teams, top down and bottom up, from inside the company and from consultants, with widespread education and with skunk work pilots. Therefore it’s hard to give a generic playbook for how you can get it implemented.
DevOps Training and Certification
Certification as DevOps professional is a huge advantage as it marks upgradation of skills as well as enhanced capacity to improve business scope. Our certification course offers to provide an effective route to learn various processes of;
- DevOps basics
- DevOps tools
- Lifecycle
- Workflow
- Other processes
Advantages of DevOps practices and processes
Several key practices can help organizations innovate faster through automating and streamlining the software development management process. One fundamental DevOps practice is to perform very frequent but small updates. These updates are usually more incremental than the updates performed under traditional release practices. Organizations using a DevOps model deploy updates much more often than organizations using traditional software development practices. Communication and collaboration are keystones of the set of DevOps practices. Automation of the software delivery process establishes collaboration by physically bringing together the workflows and responsibilities of development and operations. Communication across developers, operations, and even other teams, such as marketing and sales, allows all parts of the organization to align more closely on goals and projects.
DevOps methodologies
DevOps follows agile software development, born from the need to keep up with increased software development velocity and throughput agile methods. “Agile development” is an umbrella term for several iterative software development methodologies, many of which have carried over to DevOps:
- Scrum—a framework in which people can address complex adaptive problems while delivering products of the highest possible value.
- Kanban—a method for managing the creation of products with an emphasis on continual delivery while not overburdening the development team. Like Scrum, Kanban is a process designed to help teams work together more effectively.
- Scaled Agile Framework (SAFe)—a set of organization and workflow patterns intended to guide enterprises in scaling lean and agile practices. SAFe is one of a growing number of frameworks that seek to address the problems encountered when scaling beyond a single team.
Microservices
The microservices architecture is a design approach to build a single application as a set of small services. Each service runs in its own process and communicates with other services through a well-defined interface using a lightweight mechanism. You can use different frameworks or programming languages to write microservices and deploy them independently, as a single service, or as a group of services. Organizations may also use a microservices architecture to make their applications more flexible and enable quicker innovation. Typically, each service is paired with a small, agile team who takes ownership of the service.
DevOps is fundamentally changing how development and operations are done today. You can use the DevOps practices, process, frameworks, and workflow, based on the DevOps philosophy, to build security into your software development life cycle at speed and scale without sacrificing safety, while minimizing risks, ensuring compliance, and reducing friction and costs.
