AppSync API on Ubuntu 24.04

Amazon AppSync is a fully managed, serverless GraphQL API service that simplifies application development by enabling real-time data access across multiple data sources. It allows developers to create flexible and scalable APIs without managing servers or infrastructure.

AppSync enables applications to query, update, and subscribe to data using GraphQL, with built-in support for real-time updates, offline data synchronization, and fine-grained access control. It integrates seamlessly with AWS services such as AWS Lambda, Amazon DynamoDB, Amazon RDS, Amazon OpenSearch Service, and HTTP endpoints.

Amazon AppSync is widely used for building modern web and mobile applications, real-time dashboards, microservices backends, and data-driven APIs that require high scalability and low latency.
