Entrepreneurs, CEOs, CTOs, and IT executives are often responsible for selecting the optimal SaaS technology stack. Ultimately, this will be a deciding factor in your application’s success. You may have an incredible concept, marketing strategy, and sales staff. On the other hand, if your SaaS tech stack does not grow, develop, and change constantly, you may find yourself reworking your whole SaaS web application every other year. This method is often inefficient in terms of time, resources, and money.

A simple scan of SaaS forums reveals that issues often arise about the ideal SaaS technology stack. A succinct response to this issue would contain a language and tools that accomplish the task at hand. There are, however, languages and technologies that will simplify the life of your engineers and help you save money on web development.

What is a technology stack?

A technological stack is a programming language library, development tools, libraries, frameworks, and other software components needed to create an online or mobile application. It is a critical component of the development process and one of the first stages in developing your application. The technology stack is split into two distinct components: the front end and the back end.

Components of the technology stack for SaaS development

Determining the technology to employ to create your SaaS solution is critical to its success. The technology stack is the bedrock of your program, defining the whole development process. As a result, it has a direct impact on your development budget and timeline.

If your SaaS company currently employs a tech expert, you are already familiar with the technology stack. However, many SaaS entrepreneurs may have just a cursory knowledge of technology. For them, I’ll briefly describe the SaaS technology stack’s main components.

• A SaaS application’s frontend

The frontend of a SaaS application is the portion of the program visible to and interacted with by the user. The frontend of most web apps requires three primary components to operate properly:

• HTML
• CSS
• Javascript

• A SaaS application’s backend

In a nutshell, the backend is the component that enables the program to operate. Moreover, it entails developing business logic, establishing databases to store data, and hosting the program on servers.

As such, the backend of a SaaS application consists of the following components:

• Languages and frameworks for programming
• A computer server
• A repository of data

• Software architecture for the creation of SaaS applications

After deciding on the fundamental technology stack for SaaS development, you must design the app’s architecture. The industry is split on whether to adopt a single-tenant or multi-tenant architecture for SaaS applications.

In a single-tenant design, each user has their instance of the program (and associated infrastructure). Moreover, this implies that no client must share their database, and each customer gets their dedicated software instance.

On the other hand, multi-tenancy allows you to utilize a single software instance to service many users in SaaS applications. While users share a database, each user’s data is segregated and accessible to just that user.

• Multi-tenancy is cost-effective in SaaS.

The multi-tenant design saves time and money by eliminating the need for a dedicated set of resources.

• It necessitates the creation of a single codebase.

There are no separate code repositories for each tenant in a multi-tenant architecture. Moreover, it utilizes a single code of trust, which increases agility, simplifies software application maintenance, and lowers complexity.

• It creates an environment conducive to creativity.

Since multi-tenancy is based on a single codebase, it enables developers to innovate more quickly. When it comes to improving your SaaS application over time, faster innovation results in increased productivity.

• It enables the most significant updates.

In this case, the vendor is not obliged to upgrade the whole program in bulk; instead, a single core codebase or application is updated. Additionally, with a multi-tenant architecture, the process of spinning up a new cloud for a new client is straightforward.

How to choose the finest SaaS technology stack

The selection criteria for the best SaaS technology stack are typically based on:

• The current development language is mostly at your business.
• Software language and platforms community size.
• The lower curve of learning. For example, Python is simpler to learn from simple syntax, flexible and very intuitive reading of python code than other programming languages. SaaS businesses are currently adopting technology. For example, the SaaS sector utilizes AWS extensively.
• Easy recruitment of engineers for your SaaS tech stack (Critical).
• Potential support for the future and long term.

Moreover, your SaaS technology stack strategy must keep you nimble, ease maintenance of the development and optimize expenses.

Factors that influence the selection of Tech stack for SaaS app development

You will realize that different tech stack suits different SaaS app project development. Here’s the following reasons:

• Size of the project

Some projects are small, and some are bigger. Therefore, the magnitude of the project plays a key role in determining the ideal SaaS app development tech stack. Below is a detailed description of the project’s size in relation to the best tech stack for SaaS apps:

Large projects – larger projects mean more features. Such apps are highly interactive, and this means they require a sophisticated tech stack from the tools, coding languages, and SaaS frameworks used. Ideally, such projects will require top talents who understand the advanced technology required to make the SaaS apps successful.

Middle-sized projects – middle-sized projects require several layers of frameworks that interact with different APIs to make the app fully functional. Examples of such projects include banking and online store applications.

Small projects – Even a beginner can work on such projects successfully without experiencing technical mishaps. The developer will only require a single framework to bring the project to life. Examples of such projects are presentations and blogs.

• Scalability

Scalability makes it possible to monitor business growth and work on some areas to enhance improvement. Therefore, application scalability plays a key role in selecting the tech stack for SaaS app development. Depending on the magnitude of the SaaS app development, you should choose a technology stack that will enable you to integrate the project details with other software applications to enhance scalability.

Note: scalability is divided into two: horizontal and vertical scalability, where horizontal scalability helps to determine business growth while vertical scalability enhances the addition of new complex tasks.

• Security

Security is one of the major aspects of a successful SaaS app. In fact, most users want SaaS apps they can feel secure with. That is why it is crucial to select a tech stack that will enhance the security of the app, especially when developing a large and highly interactive app. Some of the security concerns to look into include limited time to access the data, regular backups, using credible servers, and authorization algorithms.

• Maintenance costs

After the deployment of the app is done, there is a need for maintenance to enhance the functionality of the app. Such costs, therefore, influence the tech stack required for developing SaaS apps. In this case, using open-source software will minimize the maintenance costs and enhance the consistency of the app.

• Skills of the development team

Of course, the team working on your SaaS app project development plays a significant role in choosing an appropriate tech stack. Besides, the skill levels or experience of your SaaS app development team will determine the tech stack for your project. Therefore, it is essential to choose the tech stack that works best with your team. A complex or difficult tech stack for your app development team will make the project fail. Besides, selecting an appropriate tech stack will help you minimize the costs of having to rework some parts of the project.

Conclusion 

This guide explores the ideal SaaS technology stack and helps you grasp the benefits and inconveniences of all associated IT layers. Finally, if you attempted to avoid it, it would help the usual errors made by founders and CTOs

Keeping educated, using ready-made or pre-configured solutions such as Amazon Cognito, and using popular programming languages like Python should ideally assist put you on the correct road.
