10. Application Integration
• Requires generation of events
– Push Mechanism-
• Synchronous means of publishing the event
• Real-time generation of events
– Pull Mechanism-
• Offline event integration
– How event generation helps?
• Facilitates easier integration of processes
• Enables application to create audit logs

phase
• Optimize internal integration points for resource sharing, performance
and SLAs
• Driving external integration points by standard specifications and
flexible end-points

SaaS Maturity Model
Recorded version available at
http://www.impetus.com/webinar_registration?event=archived&eid=41
Level 4 Optimizing
Highly secure multi-tenancy model (infrastructure, application & database)
implemented with ability to configure “any” licensing model, support hard SLAs,
configure per-client business process flows, and predictive monitoring (continuously
improving model)
Level 3 Adaptive
Multi-tenancy is supported via single version and “instance” of the application with
support for on-demand scalability with advanced support for diverse licensing
models, integration & monitoring
Level 2 Managed
Applications run on consolidated infrastructure to serve multiple clients with basic
support for traditional licensing models, global usage, integration, security &
monitoring
Level 1 Reactive
Each new customer requires a separate instance of the application maintained on a
per tenant basis
