Serverless Without Regret
Lambda, Cloud Functions, and Knowing When Not To
By Nadia Oyelaran and Sam Okonkwo
Multi-cloudPractitionerArchitecture
Serverless is excellent for a specific shape of workload and quietly miserable for others. The industry conversation has been unhelpfully binary about this.
This book gives you a decision procedure: the workload characteristics that make functions a good fit, the concurrency and cold-start behavior you are actually buying, the testing and local-development tax, and the migration paths out when a service outgrows the model.
Covers AWS Lambda and Google Cloud Functions/Cloud Run with equal weight.
What you'll learn
- Apply a concrete decision procedure for serverless versus long-running compute
- Model concurrency and cold-start behavior before committing
- Keep local development and testing tractable
- Plan a migration path out before you need one
