AWS Lambda now scales 12 times faster, allowing each function to scale up by 1,000 concurrent executions every 10 seconds until reaching the account's concurrency limit, providing independent scaling for each function and improving performance for high-volume traffic scenarios without any additional cost or configuration.

<p>The article discusses improvements in AWS Lambda's scaling capabilities, allowing functions to scale up to 12 times faster when handling high-volume requests.</p>
<p>Specifically, the article covers:</p>
<ul>
<li>Each synchronously invoked Lambda function can now scale by 1,000 concurrent executions every 10 seconds until the account's concurrency limit is reached</li>
<li>Each function within an account now scales independently, eliminating the "noisy neighbor" problem caused by a single function experiencing high traffic</li>
<li>These improvements benefit applications with highly variable traffic, like news sites or online stores with flash sales</li>
<li>Services like Amazon Athena and Amazon Redshift that use Lambda-based UDFs will also benefit from faster scaling</li>
<li>An example illustrating how a function scales up to the account's concurrency limit and how requests are throttled beyond that limit</li>
</ul>
