Amazon handles the servers, OS updates, capacity, scaling and logging. APIs.io catalogs 13 workflows for Lambda, including deploying a function and verifying it runs, releasing a version behind an alias, and shifting canary traffic across two versions before trusting it fully. A conversational overlay also maps plain-language questions, like asking what functions exist in a region, to the right API call. Lambda has a free tier with self-serve signup. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I safely release a new version of an AWS Lambda function without breaking production traffic? Publish a new version and point a named alias, such as 'production', at it, which lets you control exactly what code serves live traffic. For safer rollouts, a canary workflow sends a small share of requests to the new version before shifting all traffic to it, reducing the risk of a bad deploy. _Teams rolling out Lambda releases safely can track canary and alias patterns like these on daily.dev._ ### Can I manage AWS Lambda functions, versions, and aliases entirely through API calls instead of the console? Yes, every Lambda operation is available through an API, including creating functions with POST /2015-03-31/functions, listing them, fetching details, and deleting functions or specific versions with DELETE /2015-03-31/functions/{FunctionName}. Workflows chain these calls together, such as deploying a function then invoking it once to verify it runs. _Developers automating serverless deployments follow API-driven workflows like this one on daily.dev._ ### Does deleting an AWS Lambda function also remove its versions and aliases, or do I need to clean those up separately? A dedicated teardown workflow exists specifically because cleanup isn't automatic: it detaches what depends on a function before deleting it cleanly, in dependency order. There's also an audit workflow that inventories a function's versions, aliases, and event sources, useful for checking what's still attached before removal. _Engineers cleaning up serverless infrastructure safely can reference teardown workflows like this on daily.dev._ ## Similar posts on daily.dev - [You’re Paying for Servers You’re Not Using.
