Package lambda provides the API client, operations, and parameter types for AWS
Lambda.
Lambda Overview Lambda is a compute service that lets you run code without
provisioning or managing servers. Lambda runs your code on a 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, code monitoring and logging. With Lambda,
you can run code for virtually any type of application or backend service. For
more information about the Lambda service, see What is Lambda (https://docs.aws.amazon.com/lambda/latest/dg/welcome.html)
in the Lambda Developer Guide. The Lambda API Reference provides information
about each of the API methods, including details about the parameters in each
API request and response. You can use Software Development Kits (SDKs),
Integrated Development Environment (IDE) Toolkits, and command line tools to
access the API. For installation instructions, see Tools for Amazon Web Services (http://aws.amazon.com/tools/)
. For a list of Region-specific endpoints that Lambda supports, see Lambda
endpoints and quotas (https://docs.aws.amazon.com/general/latest/gr/lambda-service.html/)
in the Amazon Web Services General Reference.. When making the API calls, you
will need to authenticate your request by providing a signature. Lambda supports
signature version 4. For more information, see Signature Version 4 signing
process (https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html)
in the Amazon Web Services General Reference.. CA certificates Because Amazon
Web Services SDKs use the CA certificates from your computer, changes to the
certificates on the Amazon Web Services servers can cause connection failures
when you attempt to use an SDK. You can prevent these failures by keeping your
computer's CA certificates and operating system up-to-date. If you encounter
this issue in a corporate environment and do not manage your own computer, you
might need to ask an administrator to assist with the update process. The
following list shows minimum operating system and Java versions:
When accessing the Lambda management console or Lambda API endpoints, whether
through browsers or programmatically, you will need to ensure your client
machines support any of the following CAs:
Root certificates from the first two authorities are available from Amazon
trust services (https://www.amazontrust.com/repository/) , but keeping your
computer up-to-date is the more straightforward solution. To learn more about
ACM-provided certificates, see Amazon Web Services Certificate Manager FAQs. (http://aws.amazon.com/certificate-manager/faqs/#certificates)
