Microsoft Updates Software-as-a-Service Reference App LitwareHR with S+S
For decades, companies ran their software on their own infrastructure. Software as a Service is a new delivery model where companies pay not for owning the software itself but for using it. In the SaaS scenario, a software provider is responsible for its availability (maintenance, scalability, disaster recovery, etc.). That's what the companies pay for.This release of LitwareHR "includes enhanced backend functionality, a new Smart Client and integration with Silverlight Streaming". Architects will greatly benefit from the new package that will help them "assess performance and scalability of databases with different extensibility patterns [like] extension tables, fixed columns and XML data types".
Gianpaolo Carraro, the director of SaaS architecture in the Architecture Strategy team at Microsoft outlined the architectural challenges demonstrated in the release:
- Application customization: metadata driven application for tenant extensions at the UI, business logic and data access layers.
- Performance and scalability of extensible, multi-tenant applications.
- Service Layer design: functional web services and meta-data web services to enable different consumption experiences ( multi-head application)
- Claims based authorization
- Tenant resource provisioning
