Learn how to move Terraform state to an Amazon S3 bucket with versioning and use a DynamoDB table for locking, enabling safe team collaboration.
Learn how to switch a DynamoDB table to On-Demand capacity, verify the change, monitor cost, and understand the trade‑offs of pay‑per‑request pricing.
DynamoDB transactions let you atomically update or read across tables, but they double capacity usage and add latency. This guide explains the mechanics, shows a Node.js example, and weighs the trade‑offs so you can decide when to use them.
Learn how to build small, secure, and repeatable Ubuntu AMIs on AWS using Packer’s Ansible provisioner, with practical checks, failure modes, and design guidelines.
Interface VPC endpoints let private subnets reach SQS, Secrets Manager, and KMS without a NAT gateway. Here's the minimal design, trust boundaries, checks, and failure modes.
When a DynamoDB table in Provisioned Capacity Mode hits throttling, latency spikes and ProvisionedThroughputExceededException errors surface. This guide walks you through symptoms, a quick diagnostic table, ordered checks, targeted fixes, and when to contact AWS support.
Learn how DynamoDB Point-in-Time Recovery lets you restore a table to any exact second within the retention window, protecting against accidental writes or deletes while keeping the original table online.
A concise architecture note on when and how to apply DynamoDB TransactWriteItems for ACID guarantees across multiple items, including design, boundaries, ops, and failure handling.
