TNAPS is a freeware.NET cross-platform application server for.NET, Mono, and Java, with component-driven architecture. It is based on the concept of application business logic separation into middleware layer. This is also called three-tier software architecture. Although there are many application servers for Java platform, there are no cross-platform application servers for.NET and Mono. The main principle of TNAPS is that a developer has to write business logic only and would be able to host it and set user access policy, database parameters and other configuration without writing code – just by existing component reusage. Current version of TNAPS requires.NET 4 and Mono 2.10.1
Basics
TNAPS focuses on business logic implementation. Developer applies principle of decomposition and splits server side logic into set of components. The main idea behind this decomposition is to get business objects that provide some value to the end-user. Developer defines business objects contracts for accessing created server functionality and implement client application using contracts. After finishing set of business objects development they should be arranged into Bizlet - one server application instance in TNAPS. Bizlet contains business objects, database configuration, user access permissions and hosting parameters. Developers or end-users of the TNAPS application can decide what kind of logic provide to the respective use by granting or revoking access to particular business object. Business objects access permissions are defined at the user group level.
Features
Development of three-tier applications is straightforward.
Developer has no problems with hosting, security, channel encryption, user access management etc.
TNAPS uses.NET Remoting for network communications. That means that client application can be implemented using.NET or Mono platform only. However, developer can extend TNAPS with WCF or any other hosting technology through . TNAPS Remoting Host Provider has some advanced features: Channel Encryption, Traffic Signing and Traffic Compression.
Licensing & Pricing
TNAPS is freeware, proprietary application server.
TNAPS 3
On June 9, 2011 TN reported that TNAPS 3 is being in the early beta-testing process. TNAPS 3 features.NET and Mono compatibility as well as multiple operation systems support: Windows, Linux and Mac OS X. New major version of TNAPS application server uses component-driven approach and application can be created by combining existing components. This concept is a further development of business object approach from TNAPS 2. Other TNAPS 3 features include:
Ability to use.NET languages and Java in one application.
TNAPS Marketplace for applications and components.
Starting from version 3 TNAPS can not be called pure.NET Application Server as it supports Java hosting. However, TNAPS core engine runs inside.NET or Mono.
