<fullname>Lambda</fullname> <p> <b>Overview</b> </p> <p>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 <a href="https://docs.aws.amazon.com/lambda/latest/dg/welcome.html">What is Lambda</a> in the <b>Lambda Developer Guide</b>.</p> <p>The <i>Lambda API Reference</i> provides information about each of the API methods, including details about the parameters in each API request and response. </p> <p/> <p>You can use Software Development Kits (SDKs), Integrated Development Environment (IDE) Toolkits, and command line tools to access the API. For installation instructions, see <a href="http://aws.amazon.com/tools/">Tools for Amazon Web Services</a>. </p> <p>For a list of Region-specific endpoints that Lambda supports, see <a href="https://docs.aws.amazon.com/general/latest/gr/lambda-service.html/">Lambda endpoints and quotas </a> in the <i>Amazon Web Services General Reference.</i>. </p> <p>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 <a href="https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html">Signature Version 4 signing process</a> in the <i>Amazon Web Services General Reference.</i>. </p> <p> <b>CA certificates</b> </p> <p>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 oper
