Saas and Cloud computing

Cloud computing is a term that describes the broad collection of services. It aids in adding new services for the users quickly and cost effectively. Organizations can choose the services and know where, when and how to use and they have to pay for the bandwidth and the server resources that they need.  Cloud computing is often regarded as a stack as a response to the broad range of services SAAS, PAAS and IAAS where SAAS is software as a service; PAAS is Platform as a service; IAAS is Infrastructure as a service. SAAS is increasingly popular with SMEs, requires no hardware and software to manage and most importantly software is delivered through a browser with the advantages of scalability, security and reliability and pay per use. PAAS involves building of expensive platforms upon infrastructure with storage, database and scalability owning the same advantages as SAAS. The third in this category IAAS provides access to infrastructure Stack with full OS access, firewalls, routers and load balancing owning the advantages of pay per use and security too.
