In recent years, software as a service (SaaS) has become one of the most popular Custom application development models. SaaS is a software licensing and delivery model where software is delivered over the Internet so that users can access the application from anywhere on any device. In this blog post, we explore step-by-step how to build a cloud-based SaaS application from scratch.
What is a cloud-based SaaS application?
Any software distributed based on the Software as a Service business model from the cloud is considered a SaaS application. This means you get a full-featured solution that runs in the cloud - it doesn't take up physical storage space, it doesn't require you to buy a perpetual license, it has no performance requirements, and it's up to you or your team of experts to manage the thing. all technically sustainable.
Getting a SaaS app is like getting a shiny new bike, custom-built to suit your riding habits, all for free - it's stored in a reliable, well-equipped bike depot so you can take it with you when you need it. and only pay for it when you use it.
With that overview, imagine the profit potential you are seeing if you choose to build a cloud-based SaaS application and monetize it accordingly. But let's start at the top.
Benefits of SaaS solutions
SaaS cloud platforms are constantly replacing conventional software installed on local infrastructure. We have listed six main reasons why companies choose to develop SaaS applications.
#1 Easy to set up
SaaS applications are web-based. This means that users don't have to configure them in a complicated way. Companies also don't need to purchase infrastructure resources to run these cloud-based services.
#2 Scalability
As the business grows, companies can easily scale SaaS solutions. This allows them to handle the increasing workload and accommodate more users. In the case of traditional software that requires on-premises infrastructure, scalability often becomes a challenge.
#3 Convenient payment
The fee is included in monthly (weekly or annual) operating costs and is easier for most companies to pay than an expensive software license. The subscription naturally increases as the platform grows. However, the client company does not need to invest in additional infrastructure capacity.
#4 Instant Updates
Users benefit from SaaS software updates as soon as they are deployed. In comparison, when using mainstream software, organizations must purchase and install new versions to keep it current and access enhanced and additional features.
#5 Accessibility
Businesses can use any SaaS application anytime, anywhere as long as the Internet is available. It makes it easier to organize remote work, maintain better control and establish communication with stakeholders, regardless of their physical location or time zone.
#6 Tests and basic plans
Most SaaS products allow users to try them out before making a decision. Rather than blindly investing in an app that might not live up to expectations, users can test the features and see if they meet their needs.
Cloud-based SaaS Application Development Process
Compared to traditional software development, the process of creating a SaaS product is somewhat restricted, but there are some similarities to Custom application development. The main benefit for the end user - is no need to install stuff and clog up physical memory - it doesn't just come out of nowhere.
File and asset storage and back-end computing power still need to be addressed somehow. To do this, you need a reliable cloud provider that provides the underlying capabilities to build and support a new SaaS architecture.
So finding a smart, proven cloud service to host your SaaS platform is first on your checklist. Once you've found an agency or team of experts to work with, there are several common project implementation phases to go through.
Step 1: Define the problem
The first step in building a cloud-based SaaS application is to identify the problem you are trying to solve and plan the architecture for your Custom application development . You need to understand your target audience's needs and understand what they want from a software application. This includes doing market research, analyzing competitors, and identifying customer pain points. Once you've identified the issue, you can proceed to the next step.
Step 2: Plan the architecture
Planning the architecture of your SaaS application is critical to its success. You must decide on the technology stack, infrastructure, and custom application development model. You also need to consider scalability, availability, and security.
Some of the most important decisions to be made are:
· Technology stack: The technology stack is the combination of programming languages, frameworks, libraries, and tools that you use to build your SaaS application. You should choose a technology stack that is reliable, scalable, and well-supported. Some popular choices are MEAN (MongoDB, Express, Angular, Node.js), LAMP (Linux, Apache, MySQL, PHP), and Ruby on Rails.
· Infrastructure: Infrastructure consists of the hardware and software components needed to run your SaaS application. You must choose a cloud provider to host your application. Some popular cloud providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). You also need to choose the type of infrastructure, such as virtual machines or containers.
· Deployment model: The deployment model is how you deploy your SaaS application to the cloud. You can choose between a single-tenant or multi-tenant architecture. In a single-tenant architecture, each customer has a copy of the application. In a multi-tenant architecture, multiple clients share a single application instance.
Step 3: Choose a Cloud Provider
Once you planned the architecture for your Custom application development, you need to choose a cloud provider to host your SaaS application. The cloud provider provides the necessary infrastructure and services to run your application. Some popular cloud providers are:
· Amazon Web Services (AWS): AWS is one of the most popular cloud providers, offering a wide range of services such as virtual machines, storage, databases, and analytics.
· Microsoft Azure: Azure is a cloud computing service from Microsoft, which offers services such as virtual machines, storage, databases, and AI.
· Google Cloud Platform (GCP): GCP is a cloud computing service from Google, which offers services such as virtual machines, storage, databases, and machine learning.
Each cloud provider has its strengths and weaknesses, so you should choose the one that best suits your needs.
Step 4: Build the app
Once you've chosen a cloud provider, you can start developing your SaaS application. This includes designing the user interface, creating the database schema, and writing code. Some of the most important steps in developing a SaaS application are:
· User Interface Design: The user interface is part of the Custom application development that users interact with. You must design a user interface that is intuitive, easy to use, and visually appealing.
· Database design: The database is where you store your application's data. You must design a database schema that is efficient, scalable, and easy to maintain.
· Application code: You need to write application code using your chosen technology stack. You should follow best practices like writing clean, readable, and maintainable code. You also need to ensure that your code is secure and compliant with industry standards.
Step 5: Test the app
Before launching your SaaS application, thoroughly test it to ensure it works as expected. This includes testing functionality, performance, and security. You must have a comprehensive test plan that includes:
· Unit Testing: Unit testing involves testing each part of your application individually.
· Integration Testing: Integration testing tests how different components of your application work together.
· Performance test: **Performance test tests how your application performs under different loads and conditions.
· **Security testing: Security testing involves testing your application for vulnerabilities and ensuring that it is secure.
You should also perform user acceptance testing (UAT) to ensure that your SaaS application meets the needs of your target audience.
Step 6: Deploy the app
After testing is complete, you can deploy your SaaS application to the cloud. This includes setting up the infrastructure, configuring the servers, and deploying Custom application development code. You should follow best practices such as using automation tools to streamline the deployment process, monitoring the deployment to ensure it's successful, and testing the application after deployment to ensure it works as expected.
Step 7: Monitor and Maintain the Application
After implementation, you need to monitor your SaaS application to ensure it runs smoothly. You must have a monitoring plan that includes:
· Monitor performance: You need to monitor your application's performance to ensure that it is fast and responsive.
· Monitor availability: You should monitor the availability of your application to ensure that it is working.
· Monitoring security: You need to monitor the security of your application to ensure that it is secure and not vulnerable to attack.
You also need to maintain the app by fixing bugs, updating code, and adding new features. You must have a maintenance plan that includes:
· Regular Updates: You should update your app regularly to make sure it's up-to-date and secure.
· Bug fixing: You need to fix bugs as soon as they are reported to ensure your app runs smoothly.
· Feature Improvements: You need to add new features to your app to meet the changing needs of your target audience.
Conclusion
Building a cloud-based SaaS application involves several steps, including defining the problem, planning the architecture, choosing a cloud provider, Custom application development, developing the application, testing the application, deploying the application, and monitoring and maintaining the application. Choosing the right cloud provider, technology stack, and architecture is important to ensure your SaaS application is scalable, available, and secure. By following best practices and using automation tools, you can streamline the development and deployment process and ensure the success of your SaaS application.
