SaaS as a composite of Cloud Computing
Software as a Service, information technology management as a service, infrastructure as a service, desktop as a service, managed Software as a service, data center as a service, mobile backend as a service, and platform as a service are all derived from Cloud Computing.
For end-users, cloud computing means simplified, self-service access where IT “products” (think services like e-mail or travel booking) are listed in browse-able service catalog (for instance, app stores) and can be instantly ordered and used. Cloud also means payment based on usage and very high expectations for service availability (24/7) and access (from anywhere and with any device). End-users have become spoilt by the immediate gratification derived from their experiences consuming cloud services in their private lives. They now expect IT services to be delivered with the same speed and reliability within the enterprise. (Viarengo, 2010)
Why SaaS?
Software as a service or as short formed SaaS is also known as cloud-based Software. It’s a way of delivering a cloud-hosted application and service licensing to users. Through Software as a Service, users with access to the internet can access business applications without going through the far more aggravating process of having to install the same apps on different devices.
SaaS for individuals can be conceptualized in terms of two dimensions: cloud services and cloud storage (Vogels, 2009). Similar to cloud services, which refer to the online delivery of Software, cloud storage refers to the online delivery of data storage, for example, Amazon EC2 – part of Amazon’s web services. Cloud storage is more popularly known as Storage as a Service (STaaS). (Understanding Cloud Computing, 15)
Impact of SaaS in Businesses
Software as a Service has redefined investing in heavy machinery for data storage since one can easily subscribe and access data easily via the internet without the need to install complex applications in devices. With this in mind, growing businesses don’t require to go through the hustle of purchasing, reinstalling supplementary Software, and changing the structure of the mechanism since it is easy to scale up the module. This ease makes SaaS very cost-effective.
Effortless ease of access has made many companies and businesses adopt it because of its multiuser capabilities, making it easier for users to work together on the same module.
