This tutorial gives you an overview and talks about the fundamentals of DevOps.
What is DevOps
- The term “DevOps” typically refers to the emerging professional movement that advocates a collaborative working relationship between Development and IT Operations, resulting in the fast flow of planned work (i.e., high deploy rates), while simultaneously increasing the reliability, stability, resilience and security of the production environment.
- Our DevOps online training programme enlightens you on how DevOps differs from Agile. One tenet of the Agile development process is to deliver working software in smaller and more frequent increments, as opposed to the the “big bang” approach of the waterfall method. This is most evident in the Agile goal of having potentially shippable features at the end of each sprint . Where as DevOps extends and completes the continuous integration and release process by ensuring the code is production ready and providing value to the customer
- Although many people view DevOps as backlash to ITIL (IT Infrastructure Library) or ITSM (IT Service Management). DevOps online training programme informs you that -ITIL and ITSM still are best codifications of the business processes that underpin IT Operations, and actually describe many of the capabilities needed into order for IT Operations to support a DevOps-style work stream.
- The goal of DevOps is not just to increase the rate of change, but to successfully deploy features into production without causing chaos and disrupting other services, while quickly detecting and correcting incidents when they occur. This brings in the ITIL disciplines of service design, incident and problem management.
Basic DevOps Principles
Our DevOps training experts have outlined few basic principles to guide you through
- Referring to DevOps Cookbook, there are three ways. First way emphasizes the performance of the entire system, as opposed to the performance of a specific silo of work or department — this can be as large as a division (e.g., Development or IT Operations) or as small as an individual contributor (e.g., a developer, system administrator
- The Second Way is about creating the right to left feedback loops. The goal of almost any process improvement initiative is to shorten and amplify feedback loops so necessary corrections can be continually made.
- The Third Way is about creating a culture that fosters at two things: continual experimentation, which requires taking risks and learning from success and failure; and understanding that repetition and practice is the prerequisite to mastery.
