1. How to Choose the Right Technology
Stack for SaaS Development?
One of the most important steps to take while designing a sustainable
product or service is to pick the right set of technologies for SaaS
development.
Why?
Because a good product is not just about designing an appealing UI and
convenient UX; it’s much more beyond that. It’s all about building a stable,
secured, and maintainable product that not just wins the hearts of your
consumer but also allow you to augment your business. And that’s where
the right technology stack matters most.
Being a business owner, busy working on operational activities, and planning
a marketing strategy for your new product, you often leave the decision to
choose the technology stack on developers.

2. Of course, it’s quite a common practice to rely on your development
partner’s technology stack decision; however, make sure that your
development partner understands your business and takes into accounts all
the important features and functionalities while proposing a technology
stack.
At Dark Bears, we believe that our client should have a basic understanding
of the technology stacks and the frameworks so that we speak the same
language while communicating about the project and help reach the goal
faster. And that’s why we’ve curated this article for you.
So, without further ado, let’s explore what a technology stack is all about and
which technology we work at at Dark Bears to build our product.
Defining the structure of your SaaS product
You might have guessed that a technology stack combines the right software
tools and programming languages to bring web or mobile app ideas into
existence. Roughly speaking, web and mobile app architecture is segregated
into the front end and backend parts, which are client-facing and server as
a hidden entity.

3. Each layer of the app is built atop of each other, forming a stack. It simply
means web and mobile tech stacks are heavily dependent on each other to
perform operations, each placed below another and thus creating a block of
the typical technology stack.
The Front-end of a SaaS application
The front-end of SaaS development services are those parts that users see
and interact with. Majority of the web applications require three main
elements for front end functioning:
1. HTML:
HyperText Markup Language is a technology used by developers to structure
the content on the web page. Using the latest version, HTML 5, you can easily
structure your app’s front-end audio and video content.
2. CSS:
As the name suggests, cascading Style Sheets (CSS) styles the HTML written
document in a desirable state. The primary function of a CSS file is to format
and style the content to give it a particular look and feel.
3. JavaScript:
The most demanded programming language, JavaScript, allows developers
to add interactive elements to the web page. It makes user engagement
interesting and attractive.
Today, innumerable tools have emerged as a quick-fix solution to reduce the
manual efforts in building front-end for web and mobile. Using a particular
framework helps to take care of the page structure, interactive elements,
and design in SaaS applications.
E.g., Bootstrap is the most popular HTML framework that reduces the
innumerable workload of the developers. In such a way, the JavaScript
ecosystem is blessed with so many beautiful frameworks that serve as a
ready-made foundation for the app architecture.

4. 4. TypeScript
A superset of JavaScript, Typescript is often used in the front-end toolkit for
webpage development. Its type checking feature enables a dynamic
approach to program and code structure. As a result, typeScript is a perfect
choice if anyone is building complex and multi-tier applications.
Frontend Frameworks
Frontend frameworks are packages with prewritten, standardized code
structured in files and folders. They act as a base for developers since it’s
wrapped with pretested, functional code to build an app, along with an
ability to change the final design. Such frameworks save developers time to
write the code from scratch and make the task easier and faster. Be it
Angular, Bootstrap, Vue.JS, JQuery, or others, you can choose anyone per
your project demand.
The Back-end of a SaaS application
Even though the backend framework doesn’t hold the center stage, it’s the
main engine that drives your app and implements the logic inside it. The web
server, a part of the backend, accepts the request from the browser,
processes these requests as per the coded logic, turns to the database to
fetch results, and sends back the relevant content. Thus, the backend
consists of a database, server app, and server itself.
1. Database:
The database is a collection of records. It is generally an aggregation of data,
records, and files. There are numerous databases: MySQL, Redis, MongoDB,
and PostgreSQL, with many NoSQL and SQL databases available.
2. Server:
You will likely choose Apache, IIS, and Nginx, which could be running on-
premises or in AWS, Google Cloud, Microsoft Azure, DigitalOcean, etc.

5. 3. DevOps tools:
Terraform, Docker, Kubernetes, Ansible, Jenkins, ELK stack, Prometheus +
Grafana, and others are needed to build Continuous Integration/Continuous
Delivery pipelines (CI/CD).
4. AI/ML:
Your SaaS can benefit from in-detail data analytics powered by purpose-built
AI algorithms. Such services are available on AWS, Google Cloud, Microsoft
Azure or can be built using a variety of Python, R, or Go libraries if you’re
skilled enough.
5. Event brokers:
Kafka or RabbitMQ help streamline backend events in CQRS architectures,
distributed data sources, and other complex backend structures.
6. API:
An API is a bridge to establish a connection between Server and the client. It
helps the server pull the data and transfer it to the database. The numerous
services we use daily are highly dependent on interconnected APIs. If any of
these APIs fail, the service will not function.
All these play a significant role in SaaS development. But choosing the best
one isn’t as important as selecting an optimal set of tools for your particular
project. This is where Backend-as-a-Service comes forward.
BaaS as a way to speed up time to market
Instead of designing and implementing complex backend systems for your
SaaS, you can use BaaS from a specialized managed service provider. This
way, you’ll save time and cost by not needing to design, build and maintain
such complex software. This will also eliminate the need to hire SaaS
developers and retain talents essential to the job, as the BaaS provider will
surely do that for you.
Now, have you thought about the architecture of your SaaS? We bet it will
be multi-tenant, but you need to learn about the single-tenant approach too.

6. Software architecture for SaaS development
You can design your own SaaS to run a separate instance for every customer
to store data within a single database and separate them on other levels.
But there are pros and cons to each of the approaches.
With the single-tenant approach, you dedicate separate computational
resources for every customer. Each program runs a separate instance, and
there’s no clash to share a memory with other tenants. Though it’s more
secure, it requires more resources.
With a multi-tenant approach, your customers can share the same web-
based app, database, and/or infrastructure behind it. This is more resource-
efficient but requires extra security measures. Besides, this simplifies
updates, in-app marketing, A/B testing, and other business processes and
activities.
What factors influence the choice of a tech stack for SaaS?
Being a leading SaaS development company, it’s essential to pick the right
technology stack, especially when the options are fewer. Below are a few
factors that you can consider while choosing the tech stack for your app.
1. Code Maintainability
Going for a popular language and framework combination is a good choice,
but it should have strong community support. Think about the future;
Will you have access to the same talents who developed the code in the
future?
Will the language and framework used to build the app will be considered
legacy?
Think rationally before acting.
2. Scalability requirements
What if you want to extend and improve your SaaS app with the latest
technology and features in the upcoming years?
Will it scale easily?

7. Angular apps scale much easier than React as Angular was built keeping
scalability in mind from the beginning. So, make sure your app is dynamic
enough to scale as and when needed.
3. Time to market
The shorter it is, the bigger chances it has to outperform your competitors.
So, select the technologies and approaches that boost your software delivery
rate through automotive and repetitive operations.
