Serverless roundup at AWS re:Invent 2022

AWS re:Invent was held in Las Vegas with approximately 50,000 attendees and featured various announcements spanning new features and improvements to AWS services. The new feature of AWS Lambda SnapStart reduces cold start delays for Java-based functions by creating an immutable, encrypted snapshot of the container after initialization, allowing future invocations to launch from a warm start. Additionally, AWS Application Composer visualizes serverless architectures, while Amazon CloudWatch Logs data protection helps keep customers and certifications safe by masking sensitive information in logs. Cross-Account Observability tracks the CloudWatch logs of multiple accounts in one place, and Amazon Inspector expands its vulnerability scans to include AWS Lambda functions and layers. Other notable announcements include Amazon OpenSearch Serverless, Amazon SageMaker Serverless Inference, and serverless data and analytics options using EMR, Kinesis, MSK, and Redshift.
