At AWS re:Invent, CEO Andy Jassy announced several new services and enhancements designed to strengthen Amazon's cloud offerings, touching on computation, databases, big data analysis, machine learning, and IoT. New instance types were introduced alongside Elastic GPUs for EC2, while Lightsail aims to simplify the creation of virtual private servers. AWS Aurora now fully supports PostgreSQL, making it more attractive to enterprises wary of Oracle and Microsoft pricing. The serverless Athena service allows direct querying of S3 with SQL, and new AI services, including Rekognition, Lex, and Polly, provide developers with tools for image analysis, conversational interfaces, and text-to-speech capabilities. Greengrass extends AWS functionality to IoT devices, enabling local execution of Lambda functions while maintaining cloud integration. These developments underscore AWS's commitment to remaining at the forefront of cloud technology innovation.
