Learn AWS concepts, best practices, and real-world implementations.
NAT Gateways charge $0.045 for every GB they process, and CI runners, image pulls and package installs add up fast. Learn how to find NAT traffic in Cost Explorer and Flow Logs, move egress-only workloads like GitHub Actions runners to the Internet Gateway, and cut the rest with VPC endpoints, ECR pull-through cache and IPv6.
A Lambda unit test can pass while the deployed system still fails on IAM, the API authorizer, or the EventBridge rule. Write the scenario once, then run it two ways: in-process against real AWS, and through the deployed stack.
A brand-new on-demand DynamoDB table serves about 4,000 writes/s and throttles the rest until it grows. Measured three ways past that ceiling: wait it out, start provisioned and switch, or pre-warm the table with WarmThroughput.
Elastic Beanstalk Cluster Mode runs your app on shared EKS infrastructure. We created both environments with CloudFormation, watched buildpack builds, deploy and rollback, and hit the sharp edges: undocumented option namespaces, a provider that rejects the tier, no Spot knob, and a $73/month floor.
ECS CLI, Fargate CLI, Copilot CLI, Proton, App Runner: AWS keeps building convenience layers on top of ECS, and keeps killing them. ECS itself has barely changed since 2014. Here's the rule that follows from that.
Same dashboard built twice: once on Kinesis, S3, Glue and Athena, once on Tinybird. Query latency, a live schema change, and what the Glue crawler costs.
A look at a full year of AWS regional outages (StatusGator data plus the early 2026 incidents) and why multi-AZ and multi-region architecture is still one of the hardest things to get right, AI tooling or not.
A Kubernetes cluster can quietly move itself into other availability zones when Spot capacity runs out, and the cross-AZ traffic that follows shows up on the bill with no health signal at all. Here's how it happens and what to change.
The AWS tech stack I use for every fullstack project in 2026 - Lambda with Hono, Postgres, TanStack Start, CDK, EventBridge, and SQS - plus what it costs and why I stopped changing it.
DynamoDB now has native vector search. Learn how to store Titan embeddings next to your items, create a vector index, and use the SearchVectors API to build a related-posts feature without a separate vector database or sync pipeline.
Developers keep shipping s3:* and AdministratorAccess, and it is not laziness. The deploy loop, indirect permissions, policy size limits, and Access Analyzer gaps all push you toward wildcards. Here is what breaks and the account-level setup that works instead.
Stop getting paged at 3am for regional Lambda throttling. Learn why ClaimedAccountConcurrency is the right metric to watch, how to set a CloudWatch alarm at 70% utilization, and how to automate quota increase requests.
