History of SaaS  The term “SaaS” or software-as-a-service was first mentioned in an internal document called “Software as a Service: Strategic Backgrounder” by the Software & Information Industry Association in 2000.
Introduction to SaaS  Software as a Service (SaaS), on demand software, is a software delivery model in which software and its associated data are hosted centrally and accessed using a thin-client, usually a web browser over the internet.
Characteristics of SaaS  Easy customization  Better access  Multitenant architecture  Integration  Operational performance
characteristics  Multitenancy: This is an architecture whereby a single instance of a software app is meant to serve multiple customers.  Security and Compliance: The responsibility of the SaaS application and hardware security solely lies with the application developer. He should ensure that multiple tenants on a shared infrastructure have their data virtually segregated and made accessible to those individuals intended to access it.
Types of SaaS There are two types of SaaS 1. The Ups of SaaS No need to buy the applications, deploy them and maintain them No need to maintain the equipment and infrastructure. Lower costs
2. The Downs of SaaS Dependency on the SaaS provider Security issues Limited applications
Architecture of SaaS Application design for SaaS or cloud infrastructure requires a number of key considerations to leverage the benefits delivered by the cloud. The design of the traditional applications considered limited resources.
Architecture of SaaS  Vertical SaaS A Software which answers the needs of a specific industry (e.g., software for the healthcare, agriculture, real estate, finance industries)  Horizontal SaaS The products which focus on a software category (marketing, sales, developer tools, HR) but are industry agnostic
SaaS providers  SalesForce  LinkedIn  Workday  Netsuite  ServiceNow  Concur Technologies
Advantages  Easy to use  Scalability  Vendor accountability
Disadvantages  Robustness  Privacy  Security  Reliability  Compliance  Performance
Conclusion Use of SaaS services is pervasive in the development and deployment of modern applications In conclusion, the SaaS methodology is very mature and would play a central to the future of computing.
