DevOps

DevOps is a set of software development practices that combine software development (Dev) and information-technology operations (Ops) to shorten the systems-development life cycle while delivering features, fixes, and updates frequently in close alignment with business objectives.

Includes the cultural and professional movement that stresses communication, collaboration, integration and automation in order to improve the flow of work between software developers and IT operations professionals.

AI Prompt: DevOps

As a seasoned Application Lifecycle Management advocate trapped in a never-ending CI/CD pipeline, you’ve been asked by a curious project manager who thinks DevOps is just a cool word for "developer magic" to explain what DevOps is all about. Your request is to break it down in a way that even someone who thinks Git is just a typo for "get" can understand, while also throwing in some levity. For example, you might say, "DevOps is like the buddy cop duo of Development and Operations, where they work together to solve the crimes of slow software delivery and buggy releases, all while enjoying a shared pizza and possibly a few friendly jabs at each other’s coding standards." Adjust your tone based on your audience—if they’re more tech-savvy, dive deeper into the collaborative culture and automation tools, but if they’re just starting out, keep it light and relatable with analogies that hit close to home. The type of output should be a concise and engaging explanation that tells a story, blending education with entertainment, captivating your viewer and leaving them chuckling as they come away enlightened. As an extra twist, prompt them to share their own "DevOps horror story" for some comic relief!

Snippet from Wikipedia: DevOps

DevOps is a methodology integrating and automating the work of software development (Dev) and information technology operations (Ops). It serves as a means for improving and shortening the systems development life cycle. DevOps is complementary to agile software development; several DevOps aspects came from the agile approach.

Automation is an important part of DevOps. Software programmers and architects should use "fitness functions" to keep their software in check.

According to Neal Ford, DevOps, particularly through continuous delivery, employs the "Bring the pain forward" principle, tackling tough tasks early, fostering automation and swift issue detection.

What is ALM?

Various Tools depending of the DevOps steps:

– Figure out this Matrix.

1. Coding – code development and review, source code management tools, code merging
2. Building – continuous integration tools, build status
3. Testing – continuous testing tools that provide quick and timely feedback on business risks
4. Packaging – artifact repository, application pre-deployment staging
5. Releasing – change management, release approvals, release automation
6. Configuring – infrastructure configuration and management, infrastructure as code tools
7. Monitoring – applications performance monitoring, end-user experience

DevOps Toolchain

The 2015 State of DevOps Report discovered that the top seven measures with the strongest correlation to organizational culture are:

1. Organizational investment in DevOps
2. Team leaders' experience and effectiveness
3. Continuous delivery.
4. The ability of different disciplines (development, operations, and infosec) to achieve win-win outcomes
5. Organizational performance
6. Deployment pain
7. Lean management practices.

Adoption of DevOps success factors include:

• Use of agile and other development processes and methods
• Demand for an increased rate of production releases – from application and business unit stakeholders
• Wide availability of virtualized and cloud infrastructure – from internal and external providers
• Increased usage of data center automation and configuration management tools;
• Increased focus on test automation and continuous integration methods
• A critical mass of publicly available best practices.
