MANY PUBLICATIONS REFER TO “CLOUD COMPUTING” AND “SOFTWARE AS A SERVICE” (SAAS)?

INTERCHANGEABLY, BUT THEY ARE TWO SEPARATE CONCEPTS. THE GENERALLY ACCEPTED DEFINITIONS ARE AS FOLLOWS:
 
CLOUD COMPUTING REFERS TO A COLLECTION OF IT RESOURCES, INCLUDING DATA CENTRES, NETWORK INFRASTRUCTURE, AND SOFTWARE APPLICATIONS THAT ARE SHARED BY MULTIPLE USERS. SAAS REFERS TO THE DELIVERY MECHANISM FOR SOFTWARE THAT USES THESE IT RESOURCES.
 
SAAS ERP/CRM SYSTEMS ARE A TYPICAL EXAMPLE. WHEREAS IN THE PAST, CLIENTS HAD TO BUY AND INSTALL TO RUN ON-PREMISE ERP SOLUTIONS, SAAS SERVICES MAKE SOFTWARE IMMEDIATELY AVAILABLE THROUGH A WEB BROWSER WITH NO INSTALLATION REQUIRED. BECAUSE IT IS CONSTANTLY AVAILABLE THROUGH A FIXED SUBSCRIPTION FEE, IT IS CONSIDERED TO BE SOFTWARE PROVIDED “AS A SERVICE”. CLOUD-BASED ERP/CRM SOLUTIONS ARE THE MAIN TYPE OF SAAS SERVICE PROVIDED BY TRIGGER NETWORKS.
