Appeon PowerServer R3

Appeon PowerServer R3 by Appeon Limited is a cloud application server and deployment solution that modernizes existing PowerBuilder client/server applications with minimal code changes. It shifts data access and business logic to a secure, scalable middle tier built on C# and ASP.NET Core, exposing REST APIs that your PowerBuilder client consumes. This architecture improves performance and security, centralizes database connectivity, and enables flexible deployment on-premises or in the cloud, with optional Docker-based containerization.

Key capabilities:

• Modernizes PowerBuilder apps to an n-tier, REST-based architecture without a full rewrite
• Uses a C#/.NET middle tier for portability, performance, and maintainability
• Supports secure authentication and authorization (such as OAuth 2.0/JWT) and TLS
• Enables horizontal scalability, load balancing, and stateless server operation
• Centralizes configuration, logging, and monitoring; integrates with CI/CD pipelines
• Works with popular relational databases and consolidates all DB access in the middle tier

The R3 release streamlines migration and administration while enhancing stability, performance, and platform support—helping teams quickly bring mission-critical PowerBuilder applications to modern infrastructure with reduced risk and cost.
