From siloed software development focused around individual applications, to DevOps and collaborative sharing through GitHub, to the modern era of DevSecOps, Cloud Operations, SRE and Platform Engineering, each phase has brought its own set of challenges and opportunities for developers undertaking software projects.
Traditionally, developers, IT operations, and security teams worked separately. Code was written, tested, deployed, and only then checked for vulnerabilities. Any issues found required starting the process over. This linear approach to software development was slow and frustrating.
With the introduction of DevOps in the early 2000s, the software development process underwent a significant change. Instead of the traditional siloed approach, DevOps brought these teams together, enabling them to work collaboratively from design to deployment. This approach enabled teams to quickly respond to changes in the business or market, and increased the overall efficiency and effectiveness of operations.
GitHub, the widely popular web-based platform for version control and collaboration, has played a significant role in the success of DevOps. The platform allows development teams to work together in a centralized location, streamlining the software development process.
DevSecOps is a methodology that integrates security practices into the software development process, from design to deployment. It is an evolution of DevOps, which was designed to identify and address security issues while bringing development and operations teams together to work more efficiently and therefore increase the overall security of the software.
Cloud Operations emerged as an overarching discipline that brings together various areas such as data, machine learning, and artificial intelligence with the DevOps approach. The goal of Cloud Operations is to optimize the entire software development and operations process, from design to deployment, by embracing the principles of DevOps and extending them to other areas, including observability.
Observability is a critical component of Cloud Operations as it enables teams to gather and analyze telemetry data from various components and services in a distributed system, allowing for more effective monitoring and troubleshooting of complex systems.
Site Reliability Engineering (SRE) was created to fill the gap between software engineering and system operations. Its main goal is to create scalable and highly reliable software systems. Combining release speed (required by development teams), quality control (required by QA teams) and system stability (required by operations teams) is the core of what SRE is about.
Platform Engineering is a game-changer in software development. The methodology focuses on the design and maintenance of reusable software components, frameworks and libraries. Platform Engineering enables teams to share and reuse these components across multiple projects, reducing duplication of effort and increasing productivity. It also allows for better collaboration and communication between teams, and enables faster development and deployment of software.
As time moves on, new disciplines come to the fore: There’s always a ‘next big thing’. However, this does not mean previous disciplines are eliminated! Instead, with a true DevOps culture & mindset implemented, the new & old can interact seamlessly in contributing to a truly reliable & agile infrastructure.
