Non-Functional Requirements (NFR) are those requirements that cut across the software functionality, spanning across all the modules and features. These requirements go deep in to the architecture of a software, which is where they get addressed. Hence, it\u2019s important to understand these NFR for a given software right before the architecture phase, so that the design can address these requirements.<\/span>\u00a0<\/span><\/p>\n

SaaS is a method to deliver and license software where the software is accessed online on a subscription basis. So basically, cloud service providers offer SaaS. These providers host various applications in the cloud and make these applications accessible to users through the net.<\/span>\u00a0<\/span><\/p>\n

What<\/span> do you think are <\/span>the top 10 critical NFR for SaaS applications and the reasons behind them<\/span>? Let\u2019s break it up and look at 5 NFRs in this blog.<\/span><\/span>\u00a0<\/span><\/strong><\/p>\n

\"Top<\/p>\n

Scalability:<\/strong><\/p>\n

In an on-demand business model, it\u2019s extremely difficult to predict the load on the system. At the same time, you cannot plan for a peak load scenario as that will consume high levels of cost and resulting in inefficient use of resources. Therefore, the software should be designed to dynamically scale up and scale down based on the real-time load on the system. This is where software architects will have to leverage the cloud model to take advantage of the on-demand resource consumption model.<\/span><\/span>\u00a0<\/span><\/p>\n

Performance:<\/strong><\/p>\n

With the constant increase in internet speed and bandwidth availability there is a general tendency to expect speedy response from <\/span>internet-based<\/span> applications. Software users are going to expect the same, regardless of the type of application or the volume of processing that happens behind the screens. Therefore, architects will have to consciously take in to consideration the potential performance bottlenecks and implement designs that can help leverage concepts like asynchronous processing, micro<\/span>s<\/span>ervices architecture, multi-data availability, etc.<\/span><\/span>\u00a0<\/span><\/p>\n

Availability:<\/strong><\/p>\n

This is p<\/span>robably the most important of all the NFR<\/span>s<\/span>. The software has to be available (online) in the first place for other NFR to come in to play. Availability of the software is the biggest concern, particularly if the software addresses a <\/span>business<\/span>–<\/span>critical solution. Unplanned downtime of software can lead to heavy loss for <\/span>c<\/span>ustomers, and consequently can ruin the software provider\u2019s business. Architects will have to understand the SLA that is targeted and design the deployment model in such a way that there is no single point of failure. They should also consider Recovery Time Objective (RTO), Recovery Point Objective (RPO) factors while designing their <\/span>disaster recovery<\/span> strategy.<\/span><\/span>\u00a0<\/span><\/p>\n

Integration:<\/strong><\/p>\n

We are living in a highly connected world today, and this is only going to increase in the coming years. Customers are very particular about choosing software that not only addresses the expected features but also its ability to gel well with the existing setup at the customer\u2019s end. This leads to a situation where the software will have to talk to a disparate set of internal and external systems. Architects will have to design the software as an open system with sufficient hooks so that integration is not only feasible but also can be completed with minimal effort.<\/span><\/span>\u00a0<\/span><\/p>\n

Auditing:<\/strong><\/p>\n

From a Software provider perspective, the ownership of the system and its functioning is with the provider. Therefore, it\u2019s the responsibility of the software provider to implement the appropriate measures to track the usage of the system and the events happening within it. This information will be critical for both diagnosis purposes as well as resolving conflicts with customers. Auditing design should ensure that all the user and system actions are thoroughly recorded and stored properly so that it\u2019s easy to trace and identify the exact sequence of events that happened in the system. It\u2019s also important to store the data change (old data vs. new data) along with the timestamp and user details that induced the change.<\/span><\/span>\u00a0<\/span><\/p>\n
