60% Less Overhead, 50% Lower Costs: How an Audit Platform Modernized into a Scalable SaaS Platform on AWS

Audit Online Solution Sdn Bhd (Audit Online) is a software provider serving audit firms across the region, helping them automate compliance workflows and keep pace with evolving regulatory requirements. To better serve its growing customer base, the company embarked on a significant digital transformation, modernizing its platform into a scalable, multi-tenant SaaS offering built on cloud-native architecture.

Partnering with Galactic Network, Audit Online modernized its platform onto a serverless container architecture on AWS. The transformation delivered over 60% reduction in operational overhead and lowered infrastructure costs by 50%.

Audit Online is a software provider serving audit firms and financial institutions across the region. The company's platform is designed to help organizations manage compliance workflows more efficiently, reduce manual effort, and stay ahead of evolving regulatory requirements.

As its customer base grew, Audit Online recognized an opportunity to evolve its product into a multi-tenant SaaS platform, enabling the business to serve more customers at scale and move from a capital expenditure model to a more flexible, consumption-based approach.

Audit Online's existing platform was built on a legacy architecture that limited scalability, increased operational overhead, and made it difficult to support unpredictable workloads during peak audit cycles. Managing separate environments for each customer created significant inefficiencies, while infrastructure constraints slowed product innovation and time to market.

To achieve its transformation goals, Audit Online needed a trusted cloud partner with the expertise to modernize its architecture end to end, adopting cloud-native microservices, serverless infrastructure, and modern DevOps practices.

Galactic Network led the modernization of Audit Online's platform, establishing a secure AWS Landing Zone with standardized account structure, IAM controls, and network segmentation as the foundation for the new architecture.

Rather than a straightforward lift-and-shift, Audit Online chose to rearchitect its application from the ground up, modernizing and migrating simultaneously to adopt a fully cloud-native architecture that would scale with the business from day one.

The application was containerized and deployed across five Amazon Elastic Container Service (Amazon ECS) Fargate services, enabling a fully serverless compute model that eliminates the need for dedicated infrastructure management. A multi-AZ architecture was implemented to ensure high availability and fault tolerance across the platform.

Amazon Aurora PostgreSQL Serverless was deployed to power the multi-tenant SaaS model, dynamically scaling database capacity based on real-time demand. This design eliminates the need for separate environments per customer, significantly improving resource utilization and enabling cost-efficient scaling for unpredictable audit workloads. Together, this architecture improves scalability, reduces operational overhead, and ensures cost efficiency while maintaining resilience and governance.

The modernization empowered Audit Online to deliver a faster, more scalable, and cost-efficient platform for its customers.

By transitioning to a multi-tenant SaaS architecture, Audit Online eliminated the need to maintain separate environments for each customer, reducing operational overhead by over 60%. Serverless compute and database layers scale automatically based on real-time usage, ensuring consistent performance during peak audit cycles, without manual intervention or over-provisioning. On-demand serverless resources replaced idle capacity, lowering overall infrastructure costs by 50%.

With a cloud-native foundation in place, Audit Online is now positioned to accelerate product innovation and deliver greater value to audit firms.

With AWS and Galactic Network as trusted partners, the company is building a future-ready foundation that supports its mission of transforming the audit industry through smarter, cloud-native technology.
