Over the past two decades, the software industry has witnessed a transformative shift in how organizations operate. Among the newer manifestations is the emergence of Platform Engineering (PE). In 2023, there exists a widespread desire to address the question: “DevOps vs SRE vs Platform Engineering?” But must it be an either-or scenario? DevOps initially prioritized collaboration, while SRE incorporated customer impact and reliability. As companies grew and faced increased complexity, SRE teams expanded to ensure reliable online experiences. Platform Engineering (PE) builds on DevOps and SRE, focusing on customer-centricity and considering developers as internal customers. This talk gives an overview of Platform Engineering and explores the benefits of prioritizing self-service tooling. Witness a live demo combining CNCF projects and other open-source tools to create a reliable platform that ensures customer satisfaction, both internally and externally.
