In Appian, the application server and engines are typically installed in Appian File Storage. This is because Appian's architecture is designed for optimal performance and stability when utilizing its proprietary file storage system. Appian File Storage is integrated with the Appian environment and serves as a centralized location for application resources, including databases and files, which supports the efficient processing of applications.
Utilizing Appian File Storage allows for simplified management of application data and ensures that resources are properly secured and backed up in accordance with Appian's best practices. It also enables seamless scaling and configuration of application environments.
The other options, while valid storage solutions in various contexts, do not provide the same level of integration and support for Appian's engines and application server. Cloud Storage may offer flexible options but generally lacks the specific optimizations for Appian environments. The Local File System can be restrictive and may pose challenges with access and scalability in multi-user scenarios. Network Attached Storage can be helpful in certain setups; however, it may not be as inherently compatible with Appian's specific requirements as Appian File Storage.
