In-depth technical guides, infrastructure case studies, and code architecture patterns from the Resarv engineering team.
Architectural Deep-Dive: EC2 Spot Capacity Providers, EFS Throughput Anomalies, and Zero-CloudWatch Telemetry
How Resarv optimized container compute costs across ECS Spot clusters, eliminated EFS Elastic throughput cost anomalies, and reduced CloudWatch retrieval fees with OpenObserve and OpenTelemetry.
Technical Architecture: PDF Statement Parsing, Zero-Cost Abstractions, and Schema Drift Resilience in FinOps R²
How FinOps R² uses Rust zero-cost abstractions, Apache DataFusion in-memory query execution, and LLM schema drift protection to reconcile millions of multi-source transactions in seconds.
Architectural Pattern: Serverless Rust Lambdas, Out-of-Order Callbacks, and HMAC Signature Validation
How Resarv processes M-Pesa STK push payment callbacks with serverless Rust Lambdas, DynamoDB idempotency locks, and HMAC signature verification.
