AWS Glue is a fully managed ETL (Extract, Transform, Load) service designed to simplify data integration. It automates much of the effort in building, maintaining, and running ETL jobs by providing a serverless environment, built-in transformation logic, and native integration with other AWS services like S3, DynamoDB, and OpenSearch.

Redshift is a columnar warehouse where the one decision that matters most is how rows are laid out across compute. This article defines the service, prices it, lists the limits, then builds a serverless warehouse and reads the query plan of the same join under three distribution styles.

Last week's out-of-band Next.js release fixed two critical RCEs and one DoS. On the 15.x line, the command everyone will run does not fully fix one of them, and your scanner may never tell you.

Last time we looked at ElastiCache, the cache you put in front of a database. MemoryDB is the same wire protocol with a different promise: the data in memory is the database, and an acknowledged write survives a failover.
Most factory code is an if-statement with a class name on it. Here is the one problem the pattern really solves, the two GoF versions, and the registry you will actually write.
