Performance Engineering in SaaS- A New Step Ahead


For any purpose to accomplish, there exist two types of requirements. The prior is functional and the other or the latter one is non-functional.  Functional requirements are those on which we directly depend to get the task done.

For example, if there is an application for travel booking, and you are looking for a seat to reserve on a bus as per your requirement, then you would directly depend on the functional ability of the application. However, when you have to seek the compatibility of that application, whether it runs or not on your mobile phone, then you become indirectly dependent on the non-functional requirements of that application.

Thus, performance testing and performance engineering is all about accomplishing the non-functional requirements meanwhile its development phase at the enterprise software development company.

What is SaaS? Briefly described.

‘Software as a Service’ is a digital form of service that we get over the internet from the third party (service provider) in the form of software that handles almost everything that we need to manage while developing a product. Including application, data, server, storage, networking, operating system, middleware, and everything is managed by the third party that provides you the software as a service.

Those who are concerned about how to build a SaaS application having performance engineering embedded into it should hire dedicatedly managed qa services along with some dedicated software developers with better SaaS acquaintance.

Performance Engineering in SaaS

As far as the performance of the software is concerned, it is the sole responsibility of an engineer or the developing team to ensure its quality unless it is not fully developed. Post to which, it becomes a liability of the product manager who might not be a dedicated developer. Thus, performance engineering is nothing but a collaborative work of product developers, engineers, quality testers, and managers altogether.

Apart from functionalities, there have been many other complications and challenges meanwhile testing a SaaS product. There used to be some challenges meanwhile the testing process is now resolved effectively. The challenges were :

  • Validation issues
  • Frequent updates
  • Multiple users from different locations
  • Standardization of an application
  • Privacy and security maintenance

So as to recover and overcome some of these challenges, performance engineering has come up with some of the smarter solutions and techniques that includes:

  • Performance engineers have started observing the patterns at which the challenges arrive within the organization and the locations of unique users so that the testing could be made even efficient without hindering other users simultaneously.
  • White box and Black box testing have become a new part of testing.
  • Even the smallest unit of an application is tested i.e. Component testing.
  • Regression testing, integrated testing, are welcomed into the testing line up.
  • API testing is done even more cautiously to check and assure the overall performance of the product or software.
  • Encryption is given even intensive care.

Conclusively, automation helps in testing SaaS products a lot. And that is an advantage of having a SaaS product.

What makes SaaS product testing different but beneficial?

SaaS-based products require way fewer resources for the testing process than an ordinary development product. The reason being its cloud-based development. Its service-oriented architecture and existence over the internet make it to be tested quicker than the traditional manner.

Its on-air availability requires as well as consumes a shorter testing span. Even this shorter testing period involves a number of factors checked within. And they are as follows:

  • Scalability
  • Optimization of the software
  • UI compatibility testing
  • Data integration
  • Performance testing
  • Privacy testing
  • Logical testing
  • Stress and load testing
  • Workflow testing
  • Migration testing

There are some factors which makes SaaS development complex are as follows:

  • ROI (Return on the investment)
  • Security sensitivity
  • System complexity
  • Integration and Migration issues
  • Platform compatibility

Software development companies give a note before deploying SaaS development services because of all these factors mentioned above. As they affect the overall performance of an organization. And that could not be compensated just for enhancing the performance of a product.

Why a new step is required?

Post pandemic this year, the entire work system across the globe has gone disturbed, as well as decentralized due to lack of physical communication. That did affect the frequency of development and raised the requirement of something that could surpass or overcome this work from home effects.

However, the cloud computing consulting services were already there in the market as well as in the development world, but they got a stronger push towards growth only after COVID-19. Continuity within the work, accessibility, scalability, connectivity, and flexibility are some of the forever requirements that were not to be or to be least compromised at any condition. And that’s why a new step into the field of development be it then SaaS or traditional enterprise solutions is required.

Performance engineering is a term yet less known or even unknown to some of the geographical areas. But that will not take much longer to spread across the globe as it is a pandemic given requirement, this could be soon foreseen all around the world even in remote areas.


Enterprise solutions are the real bones to digest for revenue generation. SaaS and cloud computing solutions not only added to the queue but also have raised a demand for themselves across the market. Although SaaS is a part of the enterprise industry, the probability of being opted by an industry player or an enterprise solution service provider is a card to look at sharply.

Microsoft Cloud named Azure, Google Cloud, Alibaba Cloud, Amazon web services are the big players of cloud computing. Each has grown at the best possible rate meanwhile this period of contingency over connectivity. It is envisaged that by the next quarter of the decade, the cloud is going to take over more than half of the work system permanently and SaaS could be the largest segment of the enterprise sector. However, PaaS (Platform as a service) and IaaS (Infrastructure as a Service) are the other two cloud computing platforms covering and growing at their best frequencies but not like SaaS.
