AWS AppSync vs Perspectium DataSync comparison

AWS AppSync simplifies application development by letting you create a flexible API to securely access, manipulate, and combine data from one or more data sources. AppSync is a managed service that uses GraphQL to make it easy for applications to get exactly the data they need.

With AppSync, you can build scalable applications, including those requiring real-time updates, on a range of data sources such as NoSQL data stores, relational databases, HTTP APIs, and your custom data sources with AWS Lambda. For mobile and web apps, AppSync additionally provides local data access when devices go offline, and data synchronization with customizable conflict resolution, when they are back online.

Perspectium DataSync is delivered as a comprehensive application in ServiceNow that allows sophisticated data synchronization scenarios to be created without coding. Your data is secure and private due to end-to-end and at-rest encryption, and the performance of your application instances are minimally impacted due to “push” data streaming. By utilizing a message queue, DataSync removes the need for data endpoints to be up and functional all the time, eliminating risk of data loss during intermittent outages at the endpoints. Additionally, due to our use of message brokering, your data stream can be flexibly re-configured without any change to the source - allowing you to flow your data to different targets with minimal impact, and automatic schema creation and maintenance of your data lake means data appears as soon as the schema changes.
