Cloud computing has changed the face of information technology today. Everything, from software applications and operating systems to databases and entire infrastructures, is available as a service through the cloud. Three important ways in which cloud computing has changed our lives are: SaaS (Software as a Service), IaaS (Infrastructure as a Service), and PaaS (Platform as a Service). We are focusing more on SaaS here. Enterprise apps, the ones that are fundamentally used by corporates for various functionalities, can be better implemented with the help of SaaS.
Load testing and performance testing are two major areas in which SaaS can be used extensively. In load testing through browsers, users and applications are properly emulated in order to find the breaking point of any application, website, or service.
Where Does SaaS Come in?
SaaS is in use by all sorts of technology companies today. Look at Salesforce.com for instance. It is a complete Customer Relationship Management (CRM) solution available in the SaaS form. GoToMeeting is another SaaS offering that many companies use for conference calls. The data and the application are served over a high-speed network to the end users. SaaS model has several advantages:
Lower costs: SaaS helps companies reduce costs as generally the SaaS is subscription-based rather than purchased on a licensing basis. This also makes it easy to increase the user base for the SaaS provider.
Scalability: SaaS is completely scalable and can be seamlessly integrated to other SaaS environments. SaaS provider takes care of all the infrastructure provisioning, installation, and database support.
Easy upgrades: SaaS is entirely remote and easy to use. Since client systems do not need any software installation, upgrading, maintenance, and new releases of an application becomes painless. Customers access the SaaS directly using their browsers.
