SaaS Tools

To understand the power of SaaS, it is important to become familiar with architecture that is multi-tenant. One of the biggest factors that prevents more organizations from adopting SaaS is the issue of trust. This is understandable since in today’s world, in the Information Age, data is critical to the success of any business, regardless of the industry that business is located in.

Some of the data that all businesses jealously guard is data related to suppliers, clients, products, and workers. If this data is compromised and falls into the wrong hands, the consequences for the organization can be disastrous. Data is at the very center of SaaS. The SaaS based apps will offer customers with access to data that is heavily centralized.

They also have a smaller amount of overhead, particularly when it comes to applications that are installed locally. To take full advantage of the power that is associated with SaaS, the company will need to give up a degree of control over their data, and they will need to be able to rely on the SaaS vendor to make sure this information is closely guarded, shielded from prying eyes.

Maintaining this trust is one of the most important priorities of SaaS vendors, and under no circumstances should it be taken lightly. What this means is that the architecture for SaaS must be powerful and highly robust, but more than anything else, it needs to be highly secure.

Any organization that is seriously considering SaaS will be nervous when it comes to revealing their sensitive information to sources which are external to their organizations. It is also important for the SaaS vendor to make sure the tools are cost effective, not only to purchase, but also to maintain. This naturally leads to the issue of creating applications which are multi-tenant.

While the SaaS model is high level and has a number of powerful advantages, it isn’t without its challenges. SaaS vendors who are designing the tools must pay close attention to things such as the total security, the design of the interface, and other factors. It is also important to pay close attention to data which is shared, and data which is isolated.

Approaches for Handling Multi-Tenant Data

There is an important difference that must be understood when it comes to data which is shared, and data which is isolated. Much of these differences involve variations which are important when it comes to the extremes. The architecture of data is a subject for which the total degree for isolation regarding the SaaS application may vary depending on the business or technical issues that must be considered.

Veteran architects of data will typically be utilized since they can handle a wide spectrum of issues when it comes to the design of the architecture, particularly when it comes to properly meeting specific sets of challenges, and there is no difference when it comes to SaaS. 

It is also important to pay close attention to databases which are distinct. Placing the tenant data inside databases which are distinct is the most basic approach for isolating the data. One approach makes use of distinct databases for every tenant.

The application code and resources for computing will in most cases be shared among every tenant for the server, but every tenant must maintain its collection of data so that it remains isolated from that data which is associated with the other tenants.

The metadata will see the database as being connected to the proper tenant, and the security mechanisms within the database will stop the tenants from accidentally gaining access to the data which is associated with the other tenants

The Second and Third Approach

With the second approach, once the customer decides to subscribe to any given service, the subsystem associated with the provisioning will generate a collection of tables which are discrete, and they will connect it to the schema which is related to the tenant’s schema.

Developers can utilize the CREATE command in SQL in order to generate the schema and allow the user to access it. With the third approach, each user will use the identical group of tables, and the ID for the tenant will be connected to every tenant that has rows it contains.
