The Top 6 Things to Think About When Making a SaaS App


The product development market for software-as-a-service (SaaS) is flourishing, attracting companies from all over the world to its services and products. With each passing year, more firms are making investments in SaaS application development and cloud migration strategies. Gartner predicts that SaaS solutions will generate $105 billion in sales in 2020, an increase of $20 billion from their prediction for 2019.

The fundamental advantage of a SaaS-based architecture is that it enables scalable and dependable cloud applications at a lower per-user cost. In a very competitive and difficult economy, SaaS apps help businesses become more adaptable and nimble. It is also inherently faster to use the SaaS paradigm to deliver more commercial value. However, an organization needs to consider these six aspects while selecting a saas application development Company.


Multi-tenancy is a term used in software design to refer to the use of a single instance of a program to serve multiple customers at the same time from a single computer. By employing a common infrastructure and codebase, developers are able to provide their services to a greater number of clients at a lower cost.

An architecture that accommodates multiple tenants will make it easier for developers to keep the product running properly. However, there is a significant security concern because multiple tenants share the same infrastructure, placing them in danger of data loss, abuse, and privacy violations, amongst other things.

It is your responsibility, as well as the responsibility of your SaaS application development company, to ensure that your multi-tenancy program enforces authentication and permissions in order to provide access to critical data. The most successful approach is to use a SaaS platform that includes tenant and data management modules built-in.


Because the application is hosted in the cloud and the database is built to be inherently scalable to handle the increased load, traditional applications have a limit on the number of users who can access the application; modern SaaS applications, on the other hand, allow an unlimited number of users to access the application.

The amount of users and transactions in SaaS systems causes the database size to grow exponentially, putting strain on database performance and resulting in longer transaction times and worse user experiences.

A well-designed SaaS application makes it simple to cope with instances when several users need access to the same data. With load-balanced servers and a solid layer between the data and the application, SaaS applications built on the latest technologies and infrastructures grow the backend data independently of the business logic and display layers.


A SaaS application’s security is crucial, and it is mostly ensured by the SaaS application development industry and cloud infrastructure providers like Amazon Web Services (AWS). Because of the modern SaaS application architecture employed by SaaS apps, your company’s data is segregated and only available to those who require it.

The majority of firms are hesitant to implement cloud computing practices because of concerns about data security and integrity. Security-by-Design (SbD) is a security strategy that allows SaaS application developers to incorporate an infrastructure architecture that automates security controls, allowing security to be built into the IT management process at every level.

Although the SbD approach isn’t new, its importance has grown as the use of public cloud computing has exploded. Amazon Web Services (AWS) has recently made strides in promoting and formalizing the method for the cloud audience.


APIs allow a well-designed SaaS app to seamlessly interface with other apps. A seasoned SaaS application development firm guarantees that the APIs needed for integration with other SaaS or on-premise apps are available and working. Third-party developers can use APIs to expand the SaaS platform’s capabilities.

Customer relationship management (CRM) and enterprise resource planning (ERP) solutions such as Salesforce, Microsoft Dynamics 365 Sales, SAP CRM, and Oracle CRM on Demand are seamlessly integrated into the SaaS model to improve marketing and customer service interactions.

While introducing APIs to a SaaS platform increases its value, it must be done with prudence to avoid exposing the APIs to security risks and vulnerabilities.

Alignment of the technical and operational models

In some circumstances, the SaaS service is subjected to technological limitations imposed by the business model, the most notable of which is resource usage. The most recent SaaS apps allow resource usage to grow in lockstep with revenue (or at a slower rate). Another consideration is how to support a business’s billing strategy. If you’re invoicing at a metered rate, your SaaS application will correctly disclose the foundation for metering.

The amount of downtime will be minimal.

In addition to your own systems and networking teams, your SaaS application development company is in charge of ensuring that there is minimal downtime. While most SaaS application development providers offer 99 percent uptime, some even go as high as 99.9%. According to various reports from IDC, Gartner, and others, businesses experience an average of 12 unplanned application downtime occurrences each year.

Here are some scenarios that your SaaS program must handle to ensure service continuity:

  • Servers that handle databases or applications are unavailable.
  • Only a portion of the functionality is lost if a third-party server is unavailable.

Because the cost of downtime is so significant, disaster recovery planning is critical for firms to minimize risks. Request that your SaaS vendor reviews your disaster recovery plan in a temporary environment, rather than causing harm to your application’s live environment. Other measures that businesses should take or seek from their SaaS application vendor to mitigate the dangers of frequent downtimes include:

  • Updates and security patches for servers are applied on a timely basis.
  • Debugging and debugging are two terms used interchangeably to describe the process of identifying and
  • Files-only, bare metal, and VM snapshots are all options for server restoration.

Thoughts for the End

A well-designed SaaS application will benefit both your organization and your SaaS application development services supplier. Despite the numerous advantages of a SaaS application architecture, these six factors are crucial for a company’s long-term viability. A solid cloud-based SaaS solution provides security and scalability, as well as ease of use and economies of scale.
