Introduction
Clavis Fintech is a growing financial technology company delivering secure and scalable digital solutions to its customers. To support rapid growth, Clavis required a cloud architecture that ensured strong governance, scalability, and operational efficiency while safeguarding sensitive financial data.
The solution was designed to:
- Establish a secure and governed multi-account AWS environment.
- Provide scalability for production and development workloads.
- Strengthen security foundations with encryption, access control, and monitoring.
- Enable cost transparency and operational efficiency through centralized services.
Business Challenge
Clavis Fintech initially operated all of its workloads within a single AWS account, with limited governance, monitoring, and compliance controls. As the business grew, the following challenges surfaced:
- Lack of governance and security boundaries between development, staging, and production environments.
- Scalability concerns as new applications and services were onboarded.
- Regulatory compliance risks due to insufficient auditing and monitoring.
- Operational inefficiencies from manual processes in deployment and account management.
Proposed Solution
Atomic Computing partnered with Clavis Fintech to design and implement a secure, scalable, and compliant AWS environment tailored for SMB growth. The engagement included:
- Landing Zone Implementation: Designed and deployed an AWS Control Tower–based Landing Zone with a multi-account strategy (separating dev, staging, and production).
- Security & Compliance: Implemented AWS IAM, SCPs, AWS Config, and CloudTrail for strict governance and compliance auditing.
- Resilience & Scalability: Introduced cross-account replication to ensure business continuity and disaster recovery.
- Automation: Leveraged AWS Systems Manager and CloudFormation for infrastructure automation and consistent deployments.
- Cost Optimization: Applied AWS Budgets and Cost Explorer to provide visibility and control over SMB cloud spending.
Outcomes & Benefits
Following the transformation, Clavis Fintech achieved measurable improvements:
- Improved Security & Compliance: Enabled audit trails that reduced compliance reporting time by 60%.
- Operational Efficiency: Automated deployments reduced manual overhead, enabling the small IT team to focus on innovation.
Systems Manager automation saved ~80 staff hours/month. - Scalability & Growth: The new multi-account, multi-region architecture allowed Clavis Fintech to seamlessly scale services as customer adoption grew.
- Resilience: Disaster recovery setup reduced RPO from 24 hours to <1 hour and RTO from 12 hours to 2 hours.
- Cost Control: With FinOps practices in place, Clavis FinTech optimized cloud spend and avoided unnecessary overhead, saving an estimated 15–25% in costs annually.
