Lerian Midaz - Open-Source Ledger System

Midaz Foundation provides a complete, production-ready infrastructure for deploying the Midaz open-source ledger system on AWS. This CloudFormation-based solution automates the deployment of all required components, enabling financial institutions and fintech companies to launch a robust ledger system in minutes instead of weeks.

Deployment Modes: Choose the deployment option that fits your needs:

• Full Stack: Deploys both infrastructure (EKS, databases, networking) and the Midaz application via Helm in a single CloudFormation stack.
• Infrastructure Only: Deploys all AWS infrastructure components (EKS cluster, RDS, DocumentDB, ElastiCache, AmazonMQ, VPC) without the application. Ideal for teams who want to manage the Helm deployment separately.
• Application Only: Deploys the Midaz Helm chart to an existing EKS cluster provisioned by the Infrastructure stack. Use this to update or redeploy the application independently.

Infrastructure Components:

• Amazon EKS cluster with managed node groups for container orchestration
• RDS PostgreSQL with Multi-AZ support for transactional data
• Amazon DocumentDB (MongoDB-compatible) for flexible document storage
• Amazon ElastiCache (Valkey/Redis) for high-performance caching
• Amazon MQ (RabbitMQ) for reliable message queuing
• VPC with 3-tier subnet architecture (public, private, database)
• AWS Load Balancer Controller and ExternalDNS for traffic management

Enterprise Security:

• Customer-managed KMS keys for encryption at rest
• TLS/SSL encryption for all data in transit
• AWS Secrets Manager for credential management
• IAM Roles for Service Accounts (IRSA) for Kubernetes workloads
• Security groups following least-privilege principles
• VPC endpoints for private AWS API access

High Availability & Scalability:

• Multi-AZ deployment across 3 availability zones
• Auto-scaling EKS node groups
• Database replication and automated backups
• Configurable resource sizing for development to enterprise workloads

NOTE - Infrastructure Costs: This product deploys a full AWS stack via CloudFormation including Amazon EKS, RDS PostgreSQL, DocumentDB, ElastiCache, and AmazonMQ. Estimated monthly infrastructure costs vary by region and usage. We recommend reviewing the AWS Pricing Calculator before deploying.
