Application integration
Application integration is the combining of multiple, similar applications, such as Web servers, onto one consolidated server.
Application integration is also the combining of different application workload types within a single server/system and migrating an application or data to a new platform in order to collocate the application and data.
It reduces administration, operation, and facilities costs and increases reliability and availability.
The main objective of application integration is to migrate applications from one or several locations to a single location. Based on the consolidation platform, this migration can take different forms:
–The migration may not bring any additional costs beyond that of relocating the application on a new server.
–The migration may imply that application programs have to be recompiled in order to run on the new platform.
–The migration may imply that application programs have to be redesigned and rewritten in order to run on the consolidation platform. As for physical server consolidation, application integration has several cases.
–Application integration is combining different application workload types within a single server or system.
–Distributed systems do not run identical applications and system software and have to be integrated into a consolidation server running a different operating system.
From another point of view, consolidation takes one of three basic approaches:
Logical
Logical consolidation brings all server resources to the same level so that they can be viewed logically as a single unified environment.
In logical consolidation, actual systems are still distributed, while administrative procedures and processes are standardized
Physical
Physical consolidation does pretty much what it says: systems are relocated to a single server site. The number of servers you have to manage remains the same, and cost savings come from better staff utilization, higher service
