Digest #131: Lambda@Edge, Nix vs. Docker, DynamoDB Secrets!
Lambda@Edge, Terraform Debugging, and This Week’s Buzz on HashiCorp, AWS, and Postgres Trends.
Welcome to this week’s edition of the DevOps Bulletin!
Unlock the secrets of seamless user version transitions with Lambda@Edge and master Terraform debugging with this easy guide. Discover the optimizations that make processing over 5 million records with Lambda possible 😱
Dive into why Nix could be your go-to for Docker image building. Learn from a real-life tale of cloud cost optimization, where merging projects into a single ECS cluster and shared RDS reaped unexpected benefits.
In the news: Explore the hidden costs of managed databases, HashiCorp’s potential sale, AWS’s new data transfer policy, Mintlify’s security incident, PlanetScale’s strategic changes, why Postgres is dominating the database scene, and how Doctolib is combating alarm fatigue syndrome 😅
