It is a lot like the IT/Ops + Development + Operations + IaaS nexus. DevOps is the combination of the Ops + Development + IaaS (Application and Infrastructure Services) + well, you get the idea.
There is a strong mutual respect between DevOps and Agile that I have yet to see expressed anywhere else.
The differences between DevOps and Agile are not just in language, or even in philosophy. In the old Agile days, Ops was taught from the beginning, and maintained from a very early age, by those who held the responsibility for implementing it.
In DevOps teams, we see a shift from being an after school club, to an after school club, to an after school club with full time jobs, to an agile team, to an agile team with full time jobs…
…to being an agile team, working on QA, writing unit tests, running CI/CD, and monitoring systems health…
…to a full time job as a DevOps Engineer or DevOps Engineer in a large organization.
In large organizations, DevOps competes with Lean, Theory of Constraints, Agile, and even Cult of Personality for top spots on the priority list. When you have multiple roles in a DevOps team, and multiple priorities, and multiple people involved in implementing a program, you run the greater risk of burnout.

DevOps is a set of software development practices that combines software development (Dev) with information technology operations (Ops) to shorten the systems development life cycle while delivering features, fixes, and updates frequently in close alignment with business objectives.
What does DevOps mean for your business? Well, in a nutshell, DevOps enables your business operations team to focus on delivering software and fix or update services and avoid complex operations processes. You can also increase operational efficiency by using automated deploys and provisioning.
How can you get started with DevOps in your company? There are a few key things you can do to get started.
Get in the #DevOpsCore movement. The DevOps conference is bringing together the voices of software industry leaders to share best practices and roadmap for DevOps adoption. Conference attendees will also have the opportunity to network with influencers and get in-person hands-on experience.
Take the Agile or DevOps Certification. The DevOps Certified Professional is an expert in their respective areas of expertise. DevOps certification helps companies and development staff better prepare for the delivery of business processes and services by operations team. Agile and DevOps are suitable career paths for people who know how to build and deliver software in accordance with business objectives. DevOps is also beneficial for development and IT operations who wish to improve their skillset in the areas of application development, IT operations, and security protocols.
DevOps is not limited to a given role. Anyone can take the DevOps Certified Professional examination.

It is a major shift in the way that organizations are managed. In the past, operations and development teams were on separate floors or even separate departments, working together on the same tasks. This was considered extremely unprofessional. Now, operations and development are inextricably linked and part and parcel of that is maintaining productivity. DevOps is the merging of the operations and development teams in a seamless way.
There are a few key practices that help organizations innovate faster through automating and streamlining the software development and infrastructure management processes. Most of these practices are accomplished with proper tooling.
One fundamental practice is to perform very frequent but small updates. This is how organizations innovate faster for their customers. These updates are usually more incremental in nature than the occasional updates performed under traditional release practices. Frequent but small updates make each deployment less risky. They help teams address bugs quicker since the bugs are already there.
However, the combination of microservices and containers makes updates less risky in the sense that you are not changing the core functionality of the application. However, you are changing the configuration of the application, which can involve changes to database configurations or application configuration. Therefore, you should be performing system configuration updates regularly.
When you build microservices, you can increase the level of automation by which updates are handled. You can use the same tooling to deploy multiple containers and then use different tools to control which application is run in each container.
