Cloudvisor started with a comprehensive infrastructure and security review, followed by targeted architectural and automation improvements focused on autoscaling, governance, security, and deployment efficiency.

1. Well-Architected Framework Review
   

   A free AWS Well-Architected Framework Review was conducted to identify architectural gaps in areas of security, reliability, automation, cost optimization, define remediation priorities, and look for potential funding opportunities for improvements.
   

2. EKS Autoscaling Optimisation with Karpenter
   

   The node autoscaling issue in Amazon EKS was addressed by planning and configuring Karpenter to dynamically provision nodes based on workload demand, reducing the need to size for peak load.
   

3. IAM and Account Governance Improvements
   

   Best-practice guidance was provided for IAM configuration, helping improve role management, access control, and overall AWS account governance.
   

4. Enhanced Security Monitoring
   

   CloudTrail and GuardDuty configurations were reviewed and improved to ensure stronger auditing capabilities and proactive threat detection.
   

5. VPC and Network Architecture Enhancements
   

   The VPC was adjusted by introducing NAT Gateways and S3 VPC endpoints, and the EKS control plane was moved to a private subnet. A Client VPN solution was designed to enable secure access to private resources within AWS network such as EKS control plane, databases and EC2 nodes.

6. Customised EKS Node Configuration
   

   EKS node AMIs were customised to pre-load Docker images and ML models, simplifying automation and reducing initialization time for AI workloads.

7. Automated CI/CD with ArgoCD
   

   An automated CI/CD pipeline using ArgoCD was implemented significantly reducing manual deployment effort and improving release reliability. Additional changes were made to enable future implementation of canary deployment.
