Challenges in SaaS Development
Some of the common challenges in developing a SaaS framework
include:
The framework needs to enable resource sharing across tenants,
while ensuring data isolation and the desired level of application
security.
To efficiently manage application quality of service requirements,
the service components should support design time integration
(tight coupling) and runtime integration (loose coupling).
The framework should co-exist with common enterprise application
development frameworks.
Commonly available SaaS frameworks have a significant learning
curve, which increases project time lines and costs.
Cognizant’s Solution
Cognizant’s Mustang.NET is a framework to jumpstart the adoption of
software-as-a-service. The framework is built using the latest Microsoft
technologies, extensible and customizable to cater to multi-tenancy
requirements of Web/rich-client applications.
This framework can be used for both new application development for
SaaS-enabling existing Web applications. Mustang.NET is aimed at
accelerating the business model transformation of clients from a
perpetual licensing model to a subscription model.
Design Principles:
Mustang.NET architecture and component
Mustang.NET is built on simple design principles to address most
SaaS challenges. Its key components include:
A layered architecture that facilitates clear separation and makes
the framework robust yet extensible.
The use of Inversion of Controls (IOC) and Dependency Injection
(DI), which allows the components and services to be used both
during design time and/or at runtime coupling.
Coexistence with other standard enterprise-class frameworks like
Castle Windsor, Microsoft Enterprise Library and Spring.NET.
