IaC has become a crucial element of most cloud-native DevOps setups, and its adoption is changing the way businesses approach IT infrastructure management. The concept of IaC was initially on the bleeding edge of DevOps less than 10 years ago, but it's now widely recognized as a key benefit of cloud computing. With the rise of cloud providers like AWS, many businesses are integrating operations into engineering teams, leading to a shift from traditional system administrators to DevOps professionals. IaC allows for automation and flexibility, enabling developers to control infrastructure from the engineering department and reducing costs for businesses. However, to fully capitalize on this trend, organizations need to unlearn outdated approaches and be willing to adapt to new technologies and concepts. This includes letting go of sunk cost fallacies and embracing flexibility and modernity in DevOps. As IaC continues to evolve, teams will focus on building common elements and giving developers room to work with custom infrastructure solutions, reducing cognitive load and enhancing the final product.
