Cloud Computing Guide For SaaS or Software as a Service provides a comprehensive guide on this Service Model of Cloud Computing which is important to any user; be of Enterprise Grade or just a free application or storage Service user. Software as a Service or SaaS is the highest point of infrastructure that is provided by a cloud provider and the provider exerts the most control in terms of configuration and customization of the solution. So from the technical perspective, this model of Cloud Computing (please compare with the other Cloud Computing Service Models here.) is the lowest in the pyramid. This guide on Cloud Computing Guide For SaaS will help you to understand the problems, advantages and solutions.
Cloud Computing Guide For SaaS : The Model
SaaS model is also identified as a model of on-demand software deployed as a hosted service, it is a cloud computing model where the software is made available directly with a complete environment with the application to use any service and relieving the user of the responsibility for the application, its configuration, and the configuration of the host system and run the application.
In fact, the basic concept of SaaS was present even prior to huge advent of the cloud. The ASP model was the first to introduce the concept of providing software as a service (SaaS), pay the flat-rate or for consumption. A typical feature of the ASP model is the provision to each clientone or more dedicated servers, on which they run applications and services, in this way, each user has a dedicated instance of the application and often customized ad hoc. SaaS service is the evolution of this model and idea, that without the installation and management software allows you to easily access applications on the Internet through web browser or a thin client, which enables a client with limited processing power for data processing.
Cloud Computing Guide For SaaS : Why We Do Not Recommend to Opt For this Option
Unless the usage is of lighter importance, it is better to avoid SaaS as basically with the huge progress of Free Softwares and Open Source Softwares, one can easily host own software on any Free PaaS, which will give some security and control than SaaS. Data security is not under the total control of the end user, and the lack of flexibility of this solution in which for example the end user has no possibility to manage the space (increasing it and decreasing) and workloads.
We suggest to use IaaS or Cloud Server to host own Free and Open Source Softwares for your own solution. iCloud by Apple is an type of exceptional service where the users can be limited by hardware identity and thus increasing the security to some extent.
