The future of SRE and Devops: Platform and Infrastructure Engineering

In the ever-evolving landscape of SRE and DevOps, one thing remains constant: change. As the industry matures, we’ve seen significant transformations, particularly with the advent of Kubernetes and containerization. These technologies have revolutionized how we manage environments, providing consistent and stable platforms that can be easily replicated across various infrastructures. Now, as Kubernetes solidifies its place in our ecosystems, the horizon is shifting toward AI-driven advancements that promise to further enhance our workflows.

Reflecting on my journey from a Systems Administrator intern at Salesforce back in 2001, when the company had just 150 employees, I recall the excitement of solving computer issues and troubleshooting what are now considered basic IT tasks.

The landscape was vastly different then and Linux became the game-changer, though installing applications and resolving dependencies could take days. Today, these tasks are automated and completed in minutes, thanks to the innovations that DevOps and SRE have brought to the table.

DevOps: Breaking Down Silos

DevOps emerged to dismantle the barriers between development and operations teams. It fosters collaboration, automates the software delivery process, and emphasizes practices like Continuous Integration and Continuous Delivery (CI/CD). The “you build it, you run it” mantra encapsulated the DevOps culture, although it wasn’t without its challenges.

SRE: Engineering Reliability

Site Reliability Engineering (SRE), introduced by Google, took a different approach by applying software engineering principles to operations. SRE focuses on reliability, availability, and scalability, utilizing metrics like Service Level Objectives (SLOs) to ensure system performance. It sought to improve on the DevOps model by emphasizing collaboration and avoiding the “throw it over the wall” mindset, which often led to inefficiencies.

Platform Engineering: The Next Evolution

Platform engineering is the natural evolution of DevOps and SRE, focusing on creating self-service platforms that empower developers. These platforms standardize tools, services, and workflows, enabling developers to concentrate on writing code rather than managing infrastructure.

The Relationship Between DevOps, SRE, and Platform Engineering

• Complementary Roles: DevOps remains crucial for fostering collaboration and automation, while SRE emphasizes reliability. Platform engineering adds another layer by abstracting infrastructure complexities and providing streamlined tools for developers.
• Developer Experience: Platform engineering is inherently developer-centric, reducing cognitive load and boosting productivity by offering pre-built, reusable components that align with both DevOps practices and SRE principles.
• Evolving Practices: As organizations mature, the lines between these roles may blur. Platform engineering might absorb responsibilities traditionally associated with DevOps or SRE, but it doesn’t replace these functions — instead, it enhances them.

In essence, platform engineering is an evolution that supports and amplifies DevOps and SRE. It provides a framework that scales these practices in increasingly complex environments.

Key Elements

• User-Centric Platforms: A focus on improving both user and developer experiences, driven by product management approaches and user feedback to constantly improve the user experience.
• Self-Service: Building platforms that are reusable and maximize efficiency, enabling developers to access tools independently.
• Balancing Control with Flexibility: Offering the options of using the default or base standards or options for customizations.

Conclusion

Platform engineering is key to simplifying the complexities of modern software development. It enhances productivity and improves the developer experience. As more organizations adopt this approach, those who invest in platform engineering will be better positioned to lead in a software-driven future.
