Some best practices for SaaS application architecture

It has been noticed that the SaaS-based application architecture in cloud computing is helpful for the developers to create scalable, error-free applications cost effectively and follow the ‘pay per use’ model.

The application design for the SaaS or cloud infrastructure demands a few major considerations to bag the advantages delivered by the cloud. The design of the conventional applications took into the account limited number of resources.

But the applications in the cloud are capable of leveraging the complete advantage of the unlimited resources, hence the architects need to opt for this change when developing cloud-based applications. When creating SaaS application, it is suggested that the development team consider the following factors to ensure the development of a quality focussed product that boosts a business.

Here are some of the best practices that should be followed by the SaaS-based application architecture.

  • Customisation and self-service

While designing, it is key to understand that a SaaS-based application should be self-serviced. In simple words, anyone who will be interested will be allowed to register and start using the service without taking help from the admin or support team.

Moreover, the details in regard to set up, comprising application use, should be offered to the users on the SaaS application. Personalisation should be an integral part of a SaaS-based app by implementing changes as per the need and personal preference of the users. In fact, the end users should be allowed to customise the ‘look and feel’ as per their choice.

  • Multi-tenancy

This focuses upon an architecture where a single instance of a software app is able to serve innumerable clients. The presence of a multi-tenant architecture allows the developers to use common infrastructure and code base that allows the expansion of the services, making it economically viable.

  • Integration

A SaaS application should be able to integrate with other applications. It is believed that a standard set of APIs should be present that will enable integration with other applications (on-premise or SaaS).

  • Performance capability

A scalable application with effective performance should be made available and also able to meet the requirements of tenants, irrespective of their size. Since the users will be accessing it over the Internet, the application should have high performance about data querying, implementing transactions and excellent rendering.

  • Security and compliance

The responsibility of the SaaS application and hardware security is dependent with the application developer.
