In the rapidly evolving world of DevOps and Cloud, a relatively new and exciting topic has emerged – “platform engineering.” Many discussions surround this concept, with questions arising about its role in DevOps. Some argue that it complements DevOps, while others believe it replaces it. In reality, it significantly changes the established rules of DevOps, SRE (Site Reliability Engineering), and Cloud Engineering, introducing new dynamics to the game.
What is Platform Engineering?
Platform engineering is a distinct role that addresses challenges in the software development and operations lifecycle. It aims to bridge the gap between developers and operations, unifying their efforts for more efficient and seamless collaboration. With platform engineering, organizations can create a unified platform that empowers developers to own the entire lifecycle of their applications, from development to deployment and operation.
The Need for Platform Engineering
To understand the significance of platform engineering, it’s crucial to recognize the issues it addresses. In the past, developers and operations teams operated independently. Developers were responsible for creating applications, while operations handled deployment and runtime. This separation resulted in communication challenges and knowledge silos, leading to slow and inflexible processes.
Challenges Faced in the Traditional Approach:
- Lack of Flexibility: Developers had to rely on operations to make infrastructure changes, slowing down the development process.
- Waiting Time: Developers often had to wait for operations to allocate resources like servers or set up Jenkins pipelines for their applications.
- Dependency on Operations: Operations, on the other hand, had to wait for developers to fix issues in the application before they could proceed with deployment and operation.
Enter DevOps
With the introduction of DevOps, the gap between developers and operations began to close. This approach brought these two teams together, breaking down barriers and knowledge silos. Developers were given more control over the application’s entire lifecycle, and operations could align better with the development process.
The Advantages of DevOps:
- Improved Collaboration: DevOps promoted seamless collaboration between developers and operations, enhancing overall productivity.
- Ownership and Flexibility: Developers now own the entire application lifecycle, including underlying infrastructure, resulting in more flexibility and faster development cycles.
- Automation: Automation is a core tenet of DevOps, enabling faster and more reliable software delivery through automated testing, deployment, and monitoring processes.
- Continuous Integration and Continuous Deployment (CI/CD): DevOps encourages the adoption of CI/CD pipelines, allowing developers to merge code changes frequently and deploy them to production quickly.
The Evolution to Platform Engineering
As organizations embraced DevOps, new challenges emerged due to increased ownership and responsibilities for engineers. The complexity of managing the entire application lifecycle brought forth the need for a specialized role – platform engineering.
Platform Engineering is a relatively newer concept that emerged to address the challenges posed by the DevOps model, particularly when it comes to managing complex and scalable applications. Platform engineers focus on creating a unified platform that empowers developers to manage the entire lifecycle of their applications, from development to deployment and operation.
The Role of Platform Engineering:
- Unified Platform: Platform engineers create a unified platform that facilitates application development, deployment, and operation.
- Empowering Developers: By providing self-service tools, developers can easily manage infrastructure resources and CI/CD pipelines.
- Reducing Cognitive Load: Platform engineers shoulder the burden of handling complex infrastructure tasks, allowing developers to focus on their core expertise.
Platform Engineering vs. DevOps and Cloud Engineering
While platform engineering complements DevOps, it is not a direct replacement. Instead, it enriches the DevOps culture by addressing the challenges that come with increased ownership and responsibilities.
- Focus: DevOps focuses on cultural and operational aspects, emphasizing collaboration and automation between development and operations teams. Cloud engineering focuses on designing and managing applications and services in cloud environments. Platform engineering concentrates on creating a unified platform to enable self-service and reduce complexity for developers.
- Scope: DevOps covers the entire software development and deployment lifecycle, emphasizing collaboration and shared responsibilities. Cloud engineering focuses on designing cloud-based solutions. Platform engineering focuses on creating an integrated platform that supports the development, deployment, and operation of applications.
- Roles and Responsibilities: In DevOps, developers and operations share responsibilities, whereas cloud engineers primarily handle the infrastructure and cloud-related tasks. Platform engineers provide self-service tools, manage the platform, and empower developers to manage their applications efficiently.
Conclusion
Platform engineering has emerged as a vital role in the ever-changing landscape of DevOps and Cloud. By fostering collaboration between developers and operations and providing a unified platform, it streamlines the application lifecycle, leading to more efficient and flexible software development. Embracing platform engineering can empower organizations to stay at the forefront of innovation in the digital era.
