Expert guidance on cloud strategy, migration, security, and optimization
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.
Read articleDisaster 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.
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.
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 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.
A comprehensive guide to building resilient event-driven systems using SQS Dead Letter Queues. Learn message retry strategies, poison message handling, monitoring patterns, and recovery workflows for production-grade distributed systems.
Data transfer fees account for 15-25% of AWS bills yet remain poorly understood. Learn the pricing model, identify hidden costs, implement architectural patterns to minimize egress, and build monitoring systems to prevent bill shock.
Multi-cloud sounds strategic, but the reality is increased complexity, duplicated tooling costs, fragmented expertise, and minimal leverage in vendor negotiations. Learn why single-cloud depth beats multi-cloud breadth for most organizations—and the rare exceptions where multi-cloud makes sense.
Lambda cold starts can add 500ms-3s latency to your API responses. Learn how to measure, diagnose, and optimize cold start performance using AWS X-Ray, CloudWatch metrics, initialization strategies, and architectural patterns that reduce P99 latency by 80%.
