Aivar partnered with the client to execute an Infrastructure/Workload Migration (IWMigrate) project, creating a production-ready, highly resilient, and secure AWS environment. The solution focused on a foundation of Infrastructure-as-Code (IaC) and a secure Multi-Account Landing Zone using AWS Control Tower.

The implemented platform streamlines operations, ensures high availability, and enforces compliance at scale by:

• Establishing a secure, compliant, and scalable foundation using AWS Control Tower with mandatory guardrails and Service Control Policies (SCPs).
• Deploying core application workloads into managed, multi-AZ Amazon EKS Clusters and utilizing AWS Lambda for serverless components.
• Migrating the PostgreSQL database to a highly available, encrypted Amazon RDS instance using AWS DMS for continuous replication and a seamless cutover.
• Implementing a comprehensive security layer using AWS WAF (Web Application Firewall) and continuous monitoring with AWS Security Hub (enforcing standards like NIST and FSBP).

he solution uses a combination of AWS foundational, container, data, and security services to ensure high availability, compliance, and enterprise-grade security for the client's platform:

• AWS Control Tower and AWS Organizations establish the secure Multi-Account Landing Zone, providing automated governance and enforcing compliance across the entire environment.
• Amazon EKS Clusters and AWS Lambda serve as the core compute layer, hosting the application in private subnets and ensuring high scalability for containerized and serverless workloads.
• Amazon RDS (PostgreSQL), with multi-AZ and read replica configuration, provides a highly available and encrypted relational data store.
• AWS Database Migration Service (DMS) ensures continuous, zero-downtime replication from the legacy GCP database to the new Amazon RDS instance.
• AWS Security Hub, AWS GuardDuty, and AWS WAF deliver centralized security monitoring, threat detection for data services (RDS, S3, EBS, EKS), and protection against common web exploits.
• Amazon CloudWatch and AWS CloudTrail provide centralized logging, monitoring, and auditing of all API calls and operational metrics for complete oversight and transparency.

• Zero Downtime Migration: The production database cutover was successfully executed within the agreed maintenance window using AWS DMS, ensuring uninterrupted service for travel agents.
• Utmost Scalability and Performance: The transition to a resilient, redundant, and multi-region architecture was completed, ready to handle current and future surges in B2B travel operations.
• Robust Security Posture: A full Control Tower Landing Zone with stringent guardrails was deployed, ensuring all workloads operate under a strict security and compliance framework (NIST & FSBP standards).
• Operational Excellence: The project delivered a fully documented and automated environment, confirming operational readiness and control for all migrated workloads.
