Nowadays, as technology is evolving more SaaS application businesses are coming up with different prospects. SaaS businesses are a rapidly growing industry that has attracted many entrepreneurs and companies over the course of time. With cloud computing and app development in the cloud, scaling in the AWS environment has become a relevant topic in the recent era. Software-as-a-service (SaaS) delivery model is highly meant for maximizing operational efficiency. This makes it a complete fit for the serverless model. Enterprises can rely on managed services for scaling and delivering the precise number of resources by eliminating the notion of servers from SaaS architecture. It simplified the architecture and operational footprint of the app significantly diminishing the operational overhead and complexity.

In this blog, we will look into the end-to-end view of a functional SaaS product with an AWS environment. It also delineates the ways to begin building a cloud-based SaaS architecture tackling issues of scalability for your organization.

SaaS Based Application

SaaS-based businesses are quickly developing and are a fast-growing industry across every nation. SaaS application businesses have occupied a major part of the software industry and cloud solutions. Many software providers are in search of transforming their applications to create a proper SaaS solution. If you have an idea about SaaS architecture, then you can remain aware of the web app architecture. In this article, we will delineate the best cloud server architecture for creating top SaaS products with the AWS environment.

AWS Architecture

Developers perform code commits using Sonarqube scanning. It helps in building code, images and GitLab's CI/CD. This is deployed to AWS Elastic Beanstalk for building scalable beanstalk applications with EC2 instances following the auto scaling mechanism.

In the case of using DynamoDB, CloudFront is installed to promote the Metabase in beanstalk leading to Postgres Database. In this way, the entire AWS architecture is followed.

The Role of GitHub (Source Repository) in AWS Architecture    

What it does & How it integrates:

GitHub is where developers store their codebase. This repository is the source for all future deployments. Developers commit their code, which triggers the deployment process. The code is pushed from GitHub to AWS CodePipeline, which automatically triggers the build and deployment process to AWS Elastic Beanstalk for the backend and AWS Amplify for the frontend.

AWS Amplify (Frontend Deployment)

What does it do, and how does it integrate?

AWS Amplify is used to deploy and host the frontend of the application, Next.js. It simplifies the deployment process and provides built-in features like authentication, GraphQL/REST API integration, hosting, and more.

Amplify Hosting is used to host static files and make them accessible to users via CloudFront (CDN). Amplify can automatically deploy changes when a new commit is pushed to GitHub, integrating the frontend with CI/CD pipelines. The frontend application (website or mobile app) can connect to the backend APIs deployed on Elastic Beanstalk.

Best SaaS Architecture To Implement Now

In this context, we have given a range of the best practices for SaaS architecture.

best practices for SaaS architecture

Building Multi-tenant Architecture

One can share computing resources with multiple customers by leveraging a multi-tenant architecture. Two ways are available to implement a multi-tenant architecture.

  • A single app instance with a single database enables users to access the same database as it redirects to a new database, and deploying them has also become easier.
  • A single app instance with multiple databases will enable users to access distinct databases within a single environment. This makes your application scale faster and provides ample resources to users.

Leverage Microservices & Monolithic Architecture

When it comes to layering a monolithic app, developers can build, patch, and change it without even influencing the entire app approach. However, if you want to opt for a microservices architecture, then it helps in structuring decoupled app platforms into a collection of services and data. Utilizing microservices can assist in managing independent services such as CI/C development practices. The Monolithic Vs Microservices architecture can be easily implemented depending on the use cases and based on requirements, as both are best practices depending on the use cases.

Designing SaaS With Data Security

Data breaches have become a major concern in most organizations. Therefore, cybersecurity should be taken as a major concern. This makes most enterprises and organizations rely on monolithic and on-premise architecture. Role-based access control RBAC is considered a core component of your SaaS architecture that can assist in improving data security.

Regulatory Compliance in SaaS

Make sure to build your SaaS app platform with compliance regulations built in, offering a vertical SaaS application architecture. It helps in building regulatory compliance into the SaaS-based architecture.

Content Delivery Network for SaaS Applications

A Content Delivery Network(CDN) is fundamentally a system of distributed servers that enables users to serve content to app users with high performance and high availability. For instance, if you have EC2 installed, CDN allows you to serve content to the user through EC2.

What is the CodePipeline in AWS architecture?

AWS CodePipeline is leveraged to automate the software release process. It administers a completely managed continuous integration as well as delivery pipeline, automating the steps of testing, building, and deploying. Its source stage is CodePipeline helping to pull the latest code from Github.

During the building stage, it uses AWS CodeBuild to build and package the application, helping to run tests and static code analysis. At the deployment stage, CodePipeline helps to deploy the application to Elastic Beanstalk for effective backend deployment.

AWS CodeBuild (Build and Test)

What it does & How it integrates

AWS CodeBuild runs the build process and can also perform unit tests, code analysis (like running SonarQube for static code analysis). CodeBuild is triggered by CodePipeline when new code is committed to GitHub. It compiles, tests, and packages the application, creating an artifact (like a .zip file). It then passes the build artifact to CodeDeploy or directly to Elastic Beanstalk and Amplify for deployment.

AWS CodeDeploy (Deploying the Application)

What it does & how does it integrate?

AWS CodeDeploy handles the deployment of your code to the AWS resources, ensuring that the new version of the application is deployed to Elastic Beanstalk or EC2 instances. CodeDeploy manages the deployment of the backend Elastic Beanstalk application. It also ensures proper versioning and rollback if needed in case of a failed deployment.

Exploring the monitoring & tracing tools of AWS architecture

Amazon CloudWatch is considered a native AWS service for logging, monitoring, and alerting on AWS resources. It comes with a cluster of core features mentioned below.

Alarms: Prepare and organize thresholds for obtaining notifications for anomalies in resource usage.

Metrics: Support an effective monitoring of CPU, disk usage, logging, and other service metrics.

Logs: Gathers and amalgamates logs from AWS resources comprising Amplify and Elastic Beanstalk.

Dashboards: Craft custom dashboards for a real-time overview of AWS services.

Amazon CloudWatch is favorable for monitoring AWS native applications, easy integration with Elastic Beanstalk, and Amplify.

Improved performance

With the help of reusing connections, PgBouncer can tackle a large number of concurrent client connections with a smaller number of actual database connections, resulting in advanced application performance.

Connection Pooling

PgBouncer helps to create a pool of database connections and reuses them instead of opening a new connection for each client request. It lowers the overhead of creating connections that can be resource-intensive for PostgreSQL.

Premium availability

PgBouncer can be leveraged in conjunction with several other tools to accomplish high availability by distributing the load across multiple PostgreSQL servers.

Resource efficiency

Assisting in reducing memory consumption on the PostgreSQL server by reusing existing connections instead of constantly opening new ones. They are beneficial for applications with numerous short-lived connections.

How RDS Multi-AZ PostgreSQL (Database) works in an AWS server architecture

Amazon RDS, or Relational Database Service, offers a completely managed PostgreSQL database with Multi-AZ support for high availability and automatic failure. At Nextbrain, PostgreSQL developers are well aware of the  integration process. The primary stage concerns the backend application hosting on Elastic Beanstalk interacting with the RDS PostgreSQL database for storing and retrieving data. Leveraging Multi-AZ  makes sure the availability with the replication of data in distinct availability zones within the same region. RDS is capable of tackling backups, scaling, and patching automatically.
