Best Practices for SaaS on AWS

In the flourishing landscape of the Software-as-a-Service (SaaS) market, businesses are increasingly driven to find the most advantageous platforms for hosting their applications, aiming to sustain a competitive edge. 

Amazon Web Services (AWS) stands out as the preferred platform, showcasing an impressive track record in hosting SaaS industry leaders such as Adobe, Slack, and Atlassian.

This article will delve into the diverse advantages of migrating your SaaS application to SaaS on AWS and briefly about the best practices you must adhere to while moving SaaS on AWS.

Let’s dive in!

Why SaaS on AWS?

Creating a Software-as-a-Service (SaaS) application from the ground up can be both costly and complex. A practical approach to mitigate these challenges is to build the development project on the foundation of an already established cloud provider.

Migration of the SaaS to the AWS Cloud can yield various benefits such as improved scalability, enhanced performance, and cost-efficiency. However, it needs careful consideration and execution to achieve a smooth transition. 

Transitioning a Software-as-a-Service (SaaS) platform to Amazon Web Services (AWS) brings forth numerous benefits across various dimensions. Let’s explore this in detail:

SaaS-Specific Features

AWS offers tailored features for SaaS companies, including multi-tenancy support, enabling multiple customers to share a single application instance, thereby reducing infrastructure costs. Elasticity on AWS allows automatic scaling of applications in response to demand fluctuations, ensuring optimal performance during peak usage without impacting the user experience. 

The AWS SaaS Factory provides direct access to insights, expertise, and resources specific to SaaS, covering critical aspects like tenant isolation, data partitioning, and identity management. 

Utilizing Amazon Aurora, a fully managed relational database compatible with MySQL and PostgreSQL, alleviates administrative burdens associated with tasks such as setup, patching, and backups.

Total Cost of Ownership Calculation with AWS

Utilize the AWS calculator to estimate costs for service configurations based on specific AWS services, app usage details, and cost per service and service group. This tool assists SaaS mobile app development experts in budgeting and planning.

Proof-of-Concept Testing on AWS

Conducting a proof-of-concept is crucial for startups before launching new features or app upgrades. AWS provides a range of services and functionalities for seamless integration, allowing startups to develop and test solutions with minimal resource commitment.

Data Protection Compliance on AWS

Addressing data protection regulations, especially across global boundaries, is simplified with AWS cloud-based SaaS application development. AWS is designed to manage global laws and privacy requirements, facilitating compliance for startup owners.

Global Market Reach through AWS Regions

AWS Regions offers global coverage of cloud computing services, enabling easy global deployment of applications without the need for multiple data centers. Building a SaaS on AWS allows strategic placement of infrastructure closer to the target audience, reducing latency and improving response times. This feature enhances the global market reach for startups.

Pay-As-You-Go Pricing

AWS SaaS adopts a flexible pay-as-you-go pricing model, eliminating upfront expenses and long-term commitments. This approach empowers businesses to scale resources based on actual usage, ensuring effective cost control. 

Unlike traditional models requiring upfront license purchases, AWS allows businesses to seamlessly add or remove users as needed, ensuring payment only for the consumed resources. The SaaS delivery model on AWS reduces costs related to hardware and software maintenance, contributing to overall cost savings.

More Agility, Less Management

AWS facilitates rapid provisioning of resources, enabling SaaS companies to swiftly respond to changing demands and scale applications on demand. 

By relying on a cloud-managed service provider like AWS, SaaS companies can allocate more time and resources to innovation, simplifying IT management needs. The serverless architecture of AWS Lambda eliminates the need to provision or manage servers, allowing developers to focus on application development without infrastructure concerns.

More Security, Less Friction

AWS provides robust security features, including Identity and Access Management (IAM) for controlling resource access and preventing unauthorized entry. Amazon CloudTrail offers a comprehensive record of all activities in an AWS account, facilitating monitoring for suspicious or unusual behavior

AWS Web Application Firewall (WAF) and AWS PrivateLink enhance security by safeguarding against common web application attacks and establishing secure connections between virtual private clouds and SaaS applications.

Serverless Architectures

Serverless architectures, exemplified by services like Amazon Aurora Serverless, contribute to cost optimization by billing only for consumed resources. These architectures empower developers to concentrate on coding instead of managing infrastructure, thereby reducing operational costs and automatically scaling to meet demand

AWS Lambda, integral to the serverless approach, proves versatile and suitable for various SaaS use cases, including event-driven processing, real-time stream processing, data analysis, and machine learning, offering quick provisioning and automatic scaling.

Time efficiency

Deploying a SaaS on AWS Cloud offers time efficiency through various means:

  • Simultaneous Application Deployment: Applications can be deployed simultaneously across multiple regions and zones, ensuring a streamlined and efficient process for global availability.
  • Elimination of On-Premises Hardware Setup: There is no need for the installation and configuration of on-premises hardware and IT infrastructure, eliminating time-consuming tasks associated with physical setup.
  • Seamless Access Anytime, Anywhere: AWS Cloud provides seamless access to cloud applications and resources for AWS users, regardless of time or location, enhancing overall efficiency and reducing potential downtimes related to geographic constraints.
  • User-Friendly Cloud Platform: The AWS Cloud offers a user-friendly platform with a smaller learning curve, expediting the onboarding process for IT teams and end-users.

These factors collectively enable SaaS companies to allocate less time to application deployment and maintenance. Consequently, IT teams can redirect their efforts towards handling other operational tasks.

Best Practices for SaaS on AWS

Here are some best practices you can follow while migrating SaaS on AWS:

Isolate access to resources with AWS IAM

Access to resource isolation can be made possible with the usage of AWS IAM. You can achieve fine-grained access control by switching to AWS Identity and Access Management (IAM). With the help of it, you can define granular permissions for individuals, to ensure that users or systems have only access to resources needed for the specified tasks. It can reduce the risks of illegal access and maintain a secure IT environment.

You can also assign IAM roles for the EC2 instances and AWS services to achieve dynamic and secured accessing management. It is possible to assign the roles to lambda functions, users, and instances, which ensures a flexible and scalable secured model.

Auto-scaling

Auto-scaling can be enabled to adjust the demanding computing resources. The number of computing resources can be scaled as per the demands, which in turn results in high availability. This elasticity ensures that your application can handle the varied workloads to achieve optimal performance during the peak period and minimize costs during less-demand periods.

To improve fault tolerance and improve system scalability, elastic load balancing disperses the incoming traffic from applications across multiple instances.
