Explain What are the Different Modes of Software as a Service (SaaS)
Software as a service (SaaS) is a cloud computing model where a third-party provider offers software applications to consumers over the internet. The services are scalable and can be modified by the users as they find necessary for their business. The SaaS applications can be accessed and used by multiple consumers simultaneously. The users are reduced of the infrastructure costs and the expenses are shared among the multiple users. The main purpose is to share the data resources between multiple users while maintaining data isolation between the users. The services are delivered in two modes.
Simple Multi-Tenancy or Cross-Grain Multi-Tenancy: It is a hosted service model where the users have their own resources that are independent of other users. It is not instantly scalable and users have to be content with low margins due to high competition. The advantage is it is simple and does not require any code modifications.
Fine Grain Multi-Tenancy: This again involves sharing of the same database among multiple users. The data is kept separate although the computing resources are shared. It is easily scalable and offers efficiency in services.
The above described are the two different modes of software as a service (SaaS) in which the service provider offers the software applications to the customer via the internet. SaaS applications can be effectively handled by multiple users making them the top choice for the companies using software through the cloud.
Both the SaaS modes mentioned above are known for offering the best working environment and thus companies choose them more often. If you are a budding business then going with any mode of SaaS will easily solve your problem and you will not face any issues.
