All things infrastructure 🚀

Atlan is an active metadata platform for modern data teams, facilitating collaboration on data assets. As part of platform team, - Collaborated with cross-functional teams to design and develop ArgoWorkflows for tenant management on EKS- Developed cloud design patterns and architectural frameworks for infra provisioning using Terraform and CD with ArgoCD- use vClusters to provision multiple virtual k8s clusters on the same EKS for cost reduction, and faster provisioning- Designed and implemented cleanup modules for AWScomponents used with ArgoWorkflows, optimizing costs- Led a Proof of Concept (POC) using Karpenter to optimizecompute allocation for efficient resource utilization.- Utilized AWS Savings Plans, MAP credits, and EDP Discounts, resulting in a cost reduction of over 60% for compute resources.- Optimized K8s workloads by incorporating Pod DisruptionBudgets (PDBs), Priority Classes, and HPA- Improve tenant reliability, cost reporting, monitoring- customer connect during P1/P0 incidents for prompt resolution- Collaborated with external partners, vendors toassess solution fit and review Proof of Concepts (POCs)- all things devops and cloud
