Can the servers running the Appian engines and application server use different operating systems?

In an Appian environment, the servers that run the Appian engines and the application server must operate on the same operating system. This homogeneity is crucial for compatibility, as these servers communicate and share resources seamlessly. Differences in operating systems can lead to inconsistencies in performance, security vulnerabilities, and potential issues with functionality, as the engines are designed to operate in a coordinated manner within a uniform environment. Running them on different systems can introduce complexities in deployment and maintenance, making it essential for them to share the same OS for optimal operation and reliability.
