Structuring Terraform for Scale: Monorepo vs. Polyrepo

How you organize Terraform code determines your team's velocity at scale. This guide compares monorepo and polyrepo strategies with real-world examples, analyzes the trade-offs for teams of 2-50 engineers, and provides decision frameworks and migration paths for both approaches.

Centralized Logging Pattern: Shipping CloudWatch Logs to OpenSearch

CloudWatch Logs works for small workloads but becomes expensive and limited at scale. Learn how to build a production-grade centralized logging pipeline using Kinesis Data Firehose, OpenSearch, and Lambda for transformation—with cost analysis, query patterns, retention strategies, and monitoring.

Spot Instances for Production? A Risk/Reward Analysis

AWS Spot Instances offer 70-90% cost savings but come with interruption risk. This guide analyzes real-world production use cases, interruption patterns, architectural strategies for handling spot terminations, and a decision framework for when spot instances are worth the operational complexity.

Building Multi-Region Active-Active Architectures (Is it Worth It?)

Multi-region active-active promises zero downtime, but costs 2-3x more and adds significant complexity. This guide breaks down when it's worth it, implementation patterns for AWS services, and how to avoid common pitfalls that turn HA into an operational nightmare.

Disaster Recovery Tiers: RPO/RTO Strategies for the Cloud

Disaster recovery isn't one-size-fits-all. Learn the four DR tiers (backup/restore, pilot light, warm standby, multi-site active-active), cost models for each approach, RPO/RTO tradeoffs, implementation patterns for AWS, testing strategies, and decision frameworks that balance business requirements with infrastructure cost.

A 15-Minute Guide to AWS Systems Manager Session Manager (No More SSH)

Session Manager eliminates SSH keys, bastion hosts, and security group port 22 exceptions while providing auditable shell access to EC2 and ECS. Learn setup, security controls, logging integration, and automation patterns that improve security posture and reduce operational overhead.

Serverless vs. Containers: A 2025 Decision Matrix for Fintech

Choosing between serverless and containers affects cost, compliance, velocity, and operational complexity. Learn the technical tradeoffs, cost models, regulatory considerations, and decision frameworks that fintech teams use to select the right architecture for payments, lending, and trading platforms.

S3 Lifecycle Policies: The 'Set and Forget' Savings You're Missing

S3 lifecycle policies can reduce storage costs by 70-95% through automated tiering and deletion. Learn intelligent tiering strategies, cost modeling across storage classes, policy design patterns, and monitoring approaches that optimize spend without sacrificing data availability.
