AWS Lambda

AWS Lambda is a serverless, event-driven compute service that lets you run code for virtually any type of application or backend service without provisioning or managing servers. Lambda runs your code on high-availability compute infrastructure and performs all of the administration of the compute resources, including server and operating system maintenance, capacity provisioning and automatic scaling, and logging.

AWS Lambda publishes 8 APIs on the APIs.io network, including Aliases API, Concurrency API, Event Source Mappings API, and 5 more.

The AWS Lambda catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 3 Spectral governance rulesets.

AWS Lambda’s developer surface includes changelog, CLI, authentication, engineering blog, FAQ, and 38 more developer resources.

Arazzo Workflows 13

Multi-step API workflows described with the Arazzo specification.

AWS Lambda Release a Version Behind an Alias

Publish a version, then either move an existing alias onto it or create the alias if this is the first release.

ARAZZO

AWS Lambda Shift Canary Traffic Across Two Versions

Read an alias, split its invocations between the current version and a canary version by weight, and read the routing back to confirm it took.

ARAZZO

AWS Lambda Deploy a Function and Verify It Runs

Create a Lambda function from an S3 deployment package, wait for it to become Active, then invoke it once to prove it runs.

ARAZZO

AWS Lambda Wire an Event Source to a Function

Confirm the target function exists, create an event source mapping onto a queue or stream, and poll until Lambda actually starts polling it.

ARAZZO

AWS Lambda Audit a Function's Versions, Aliases, and Event Sources

Walk the account's functions, then drill into one to inventory its configuration, published versions, aliases, and attached event sources.

ARAZZO

AWS Lambda Tear a Function Down in Dependency Order

Detach the event sources and the public URL that outlive a function, then delete the function and all its versions and aliases.

ARAZZO

AWS Lambda Expose a Function Over an HTTPS Function URL

Confirm a function is Active, give it a dedicated HTTPS endpoint with an explicit auth type and CORS policy, and read the URL back.

ARAZZO

AWS Lambda Find a Compatible Layer Version to Attach

Filter the account's layers by runtime and architecture, list the versions of a chosen layer, and resolve one to the exact ARN a function needs.

ARAZZO

AWS Lambda Warm a Release with Provisioned Concurrency

Publish a version, point an alias at it, allocate provisioned concurrency to that alias, and wait until the environments are actually READY.

ARAZZO

AWS Lambda Publish a Layer Version and Attach It to a Function

Publish a shared dependency layer from S3, verify the version, attach it to a function, and wait for the configuration update to settle.

ARAZZO

AWS Lambda Cap a Function with Reserved Concurrency

Read a function's current concurrency reservation, set a ceiling on its simultaneous executions, and confirm the value Lambda stored.

ARAZZO

AWS Lambda Tag a Function for Cost Allocation

Resolve a function name to its ARN, apply cost-allocation and ownership tags, and read the tags back to confirm the merge.

ARAZZO

AWS Lambda Ship New Code and Cut an Immutable Version

Upload new function code, wait for the update to settle, smoke-test $LATEST, and publish an immutable version guarded by the code hash.
