  • Defining how secure it should be?
  • Reflecting on your readiness & commitment towards the project
  • Exploring the strategies to see if they can simplify the task or not
  • Ensuring you are using the latest tech stack

1) Choose the suitable framework for SaaS

The best frontend frameworks for SaaS are Angular and React. Both of these frameworks are suitable for creating interactive and dynamic interfaces. To determine which one is best suited for web applications, let’s look at their strengths and weaknesses.


React is one of the prominent UI libraries developed by Meta. It has garnered immense popularity and is backed by the support of a large community. Unlike Angular, React is not a framework. This is the reason it is handy while developing particularly simple applications. Additionally, it is versatile enough to build complex applications, especially when there is a need to use reusable components.

React consists of an array of reusable components in the UI library. It is a go-to choice for creating visually appealing and feature-rich mobile applications. It offers the full potential to reduce development costs and ensure a smooth development process.

It will be best if you choose Angular for the following reasons:

  • For a rich interface and an array of reusable components
  • If you have an experienced & skilled React developer

React possesses potential pitfalls. Ideally, if you plan to develop an intricate project, leverage a comprehensive framework with more logic and advanced features & functionalities.

Moreover, a seasoned developer’s absence can lead to suboptimal code with bugs or other errors. This emphasizes the need for an experienced senior developer for your mobile application.


Angular is one of the premier frameworks that is particularly suitable for developing intricate web applications with advanced logic. This framework is known for its structured architecture. It is divided into three files: logic, templates, and style, which help create and deliver high-quality applications. However, its development process is meticulous and comprehensive before the initial development.

The increased time spent developing the web application offers high-quality web applications. However, the only disadvantage is that finding an Angular programmer takes a lot of work. Moreover, the fact is that learning Angular is more complicated.

It will be best if you choose Angular for the following reasons:

  • It excels if the web application is complex, with advanced logic & straight forward interface
  • Prioritize it if you are looking for high-quality code & scalability
  • Having an experienced developer who is expert & well-versed in developing web applications with Angular is optimal for web application development

Angular is not the right choice if you are looking forward to developing the simplest web application with minimal DOM manipulations.

2) Selecting backend stack components for SaaS

The backend acts as the central nervous system for maintaining the logic of your application. It consists of a system that manages the logic, processes logic from the browser, interacts with the databases, and delivers the relevant content.


Databases refer to a collection of records. It is an aggregation of data, records, and files. Examples of numerous databases include MySQL, Redis, MongoDB, and many more.


Web server tools like Apache, IIS, and Nginx run on-premises or in AWS, Google Cloud, and Microsoft Azure handle the function of incoming requests and responses.

DevOps tools

DevOps tools like Jenkins, Kubernetes, Docker, and much more help in developing CI/CD pipelines to streamline development workflows.


AI algorithms help your SaaS through in-detail data analytics. Such services are available on AWS, Google Cloud, Microsoft Azure, and many more.

Event brokers

Event brokers aid in managing backend events, especially in CQRS architectures, distributed data, and other complex backend structures.


API serves as a connecting link between the server and the client. It facilitates data transfer between them. Numerous services rely on this API, which means that a problem in a single API can cause major issues.

3) Picking a database for SaaS

DBaaS Database as a service refers to databases offered as PaaS or SaaS. Some popular DBaaS solutions include Amazon Relational Database Service, MongoDB, Amazon DynamoDB, etc which offer scalability and flexibility for SaaS applications to simplify the database management.

4) Cloud service providers for SaaS

Cloud technologies are becoming the go-to solution for storing data in the cloud. Many companies are providing these services, which are reliable enough compared to those of conventional devices.

A few tech giants providing cloud services are:-

a) Amazon Web Service –

Amazon Web Services (AWS) is the most popular cloud computing platform, providing a comprehensive suite of computing power, database storage, content delivery, and many other functions. Integration of AWS can be helpful to your business in many ways.

b) Microsoft Azure

Microsoft Azure is a global cloud service provider for building, testing, deploying, and managing. It operates on a global network managed by Microsoft and is a private and public platform. Leveraging virtualization, an abstraction layer called a hypervisor, helps to differentiate between the operating system and CPU, enabling multiple operating systems to run on it.

c) Google Cloud Platform

Google Cloud platform is one of the leading cloud services offered by Google; it runs on the same infrastructure it uses for end-user products. Utilizing its robust functionalities can help you to maximize SaaS operations and scalability.

5) Deploying and monitoring for SaaS

Understanding the fact that seamless deployment and monitoring is crucial. If one particular server is unhealthy, you must be able to restart or destroy it without issues. Implementing automated processes and infrastructure must heal itself. Due to this, you will be able to reduce the chances of intervening when things go wrong.

6) Integration of Machine Learning

ML is a robust foundation for data analytics and generating valuable insights from SaaS platforms. SaaS platforms incorporate algorithms to process data analytics and create value insights. It leverages ML algorithms for processing vast datasets efficiently, encompassing various SaaS application domains, including predictive analytics, natural language processing, and recommendation systems.

7) Microservice and Multi-Tenant Architecture for SaaS

Microservices are standalone services created by breaking down a software application into separate components. It operates independently by executing its functions without being embedded in the application, making it ideal for Software as a Service (SaaS). This modular approach guarantees expected flexibility and scalability.

8) Multi-Tenant Architecture for Designing a SaaS Application

Multi-tenant architecture refers to an architecture that allows multiple customers or tenants to access software application services in a unified space. Multi-tenancy can be economical because software development and maintenance costs are shared.

When assessing public clouds or services, IT managers should consider prioritizing vendor’s multi-tenancy support. SaaS (Software as a Service) is a model where resources like servers, heating, cooling, and security are shared, allowing businesses to focus on core activities without managing additional infrastructure or software, reducing overall maintenance costs.
