Platform engineering continues to evolve as a critical discipline for modern software development. However, infrastructure complexity is slowing down its momentum. The software infrastructure is a complex web of interrelated entities that spans much beyond a simple software catalog and cloud resources. Such infrastructure management is often driven by a team’s understanding of the implicit relationship between these entities. This is not scalable and often leads to operational challenges and loss of developer productivity. Knowledge graphs can build relationships between entities from diverse infrastructure sources and make explicit what was previously implicit knowledge. It elevates the developer productivity and its neglected counterpart - operational excellence. This talk will discuss the importance of knowledge graphs and the strategies and mental models that will help in building knowledge graphs around the software infrastructure.
