Enterprise Real Estate SaaS: Building a Multi-Tenant Kubernetes Platform with GitOps and 35% Cost Savings
Built greenfield Kubernetes platform for real estate SaaS with ArgoCD GitOps, Karpenter auto-scaling, AWS WAF protection, achieving 90% faster deployments and 35% infrastructure savings.
Key Results
From hours of manual work to minutes with automated pipelines
Optimized resource allocation with Karpenter auto-scaling
High availability across multiple availability zones
Complete platform built from greenfield to production
What We Were Solving
A growing commercial real estate technology company needed to build their entire cloud infrastructure from the ground up. They had developed a powerful SaaS platform for workspace optimization and financial analysis, but lacked the DevOps expertise to deploy it at enterprise scale.
The challenges were significant:
- No existing cloud infrastructure — everything needed to be built from scratch
- Multiple enterprise clients (Fortune 500 real estate firms) with strict security requirements
- Need for multi-tenant architecture with complete data isolation between clients
- Multiple microservices (Auth, API, AI, Data Pipelines) requiring orchestration
- Tight timeline — needed production deployment within 4 months
How We Solved It
We designed and implemented a comprehensive Kubernetes-based platform on AWS, built entirely with Infrastructure as Code for repeatability and compliance.
Infrastructure Foundation
Built the entire AWS infrastructure using Terraform with a modular architecture — VPC with public/private subnets across multiple availability zones, EKS cluster with managed node groups, and all supporting services (RDS, ECR, Secrets Manager).
Kubernetes Platform Engineering
- Deployed EKS with Karpenter for intelligent auto-scaling based on workload demands
- Implemented AWS ALB Ingress Controller with WAF protection on all public endpoints
- Set up External DNS for automatic Route53 record management
- Configured Cert Manager for automated TLS certificate provisioning
GitOps & CI/CD
- Implemented ArgoCD for declarative, Git-driven deployments with full audit trail
- Built CI pipelines with AWS CodePipeline that automatically update GitOps repo on merge
- Created Helm charts with per-tenant value overrides for multi-tenancy
Observability & Security
- Deployed Prometheus, Grafana, and Loki stack for metrics, dashboards, and log aggregation
- Integrated AWS Secrets Manager with CSI driver for secure secret injection
- Implemented Sealed Secrets for GitOps-safe secret management
Technologies Used
“QuantaCodes took us from zero infrastructure to a production-ready platform serving Fortune 500 clients in under four months. The GitOps setup they built means our developers can ship features without touching infrastructure, and the cost savings from right-sized auto-scaling paid for the engagement within the first quarter.”
