Software as a Service (SaaS) provides companies with the authorization to use software or services for a period of time like a rental instead of the traditional model in which companies must buy the software, build the server, install the operating system, install the software and customize it to meet the company business and needs. Some benefits of SaaS include ease of use and perform proof of concepts, reduced time to benefit, lower costs, higher resilience, integration and scalability.

SaaS offerings already provide maintenance such as support and products upgrades, lowering costs since it usually resides in a multitenant or shared environment where many users divide hardware and software licenses costs.

Users do not have to customize too many applications, which became easier to use since SaaS providers already apply best practices in their offerings. Also, users can create other instances to test new releases and versions without any impact to their production environment.

Several types of business can leverage the advantages of SaaS. For instance, IT consulting companies that don’t want to waste time in software installation and customizations due to fixed-price contracts with low profit margin can get benefits from the SaaS model, including cost reduction, software implementation, time reduction, better tools utilization and more resilience and availability.

IT consulting companies which uses SaaS can focus in their consulting expertise such as analysis, innovation and value-added activities related to their customers business. Also, they do not have to buy servers and software for each project and do not have to maintain them for the period that they are not being used.

In Thoughts on Cloud blogs, you can find more detailed information related to the top benefits of SaaS for IT consulting and the top five advantages of SaaS.

System z: Is it Part of SaaS?
The mainframe is a pioneer in cloud technologies such as virtualization, ability to support multitenant or shared environments and centralized resource pools. Service providers started to adopt the mainframe to deploy Infrastructure as a Service cloud environments that enable SaaS offerings to be delivered on the top of that infrastructure.

The Enterprise Cloud System cloud offering, for instance, which uses the mainframe for the cloud infrastructure, can reduce almost to half the costs compared against x86 alternatives and scale up to 6,000 virtual machines.

For more than 50 years, the mainframe has been bringing innovation and, more recently, it has become a key component of the cloud-computing environment that is being built by the enterprises. It is an excellent option for big data and analytics data processing due to mainframe processor power and speed. Also, security is native and vital to support multitenant or shared environments.
