Infrastructure-as-Apps (IaA) is a concept that extends infrastructure-as-code by incorporating GitOps management principles, thereby enabling infrastructure to be managed like applications. Coined in 2021, IaA integrates tools such as Argo CD and Crossplane to provide a continuous monitoring and reconciliation approach, ensuring that infrastructure configurations remain consistent with their desired states. This approach streamlines infrastructure management by using GitOps operators to automate deployment, monitor for drift, and facilitate rollbacks, enhancing efficiency and recovery from failures. A notable implementation of IaA is seen at CERN, where it facilitates rapid provisioning of computing resources across multi-cloud environments to handle significant data processing loads. By treating infrastructure changes as pull requests, IaA centralizes security and resource management, reducing the need for individual cloud access permissions and improving oversight. IaA promises to transform infrastructure management by making it more predictable and secure, while also simplifying resource provisioning through the use of custom resources and abstraction of cloud provider differences.
