The request and response validation is in built-in the Graph QL endpoint call which makes the API very secure at an outer layer even though the API is supposed to be publicly accessible. Review collected by and hosted on G2.com.

The pricing is competitive but still feels a touch expensive as compared to API gateway and to provide enough incentive to move big projects from API gateway to API appsync. Since Real-time updates are the catchy feature of this product, its pricing could be a little more competitive to give good market exposure to its best marketable quality.

AWS AppSync makes it easier to create a GraphQL API service. It only takes a few minutes to do it, though. The data from multiple AWS services, such as ElasticSearch, DynamoDB, and DynamoDB, can be viewed through one window (API Server). It is easy to connect AppSync with the AWS CLI called Amplify CLI, simple. AWS AppSync provides us with a significant performance boost compared to similar solutions. It works better with AWS ecosystems, especially Dynamodb and lambda DocumentDb RDS. In this example, App Sync brings together data from databases, APIs, and other backend systems into a single GraphQL endpoint. GraphQL API is one thing I like best about AppSync. Review collected by and hosted on G2.com.

As a newcomer to Amplify, utilizing AppSync can be a bit of a challenge. That's all I can think of, so I have no complaints about AppSync, in my opinion. I believe using it will further integrate our products with AWS. Review collected by and hosted on G2.com.

AWS AppSync comes with well-optimized solutions for data aggregation from various sources and exposure it as a GraphQL API. In that row, my favorite part of AppSync is it gives a massive jump on the performance increment compares to any other similar solution. When it comes to the AWS ecosystem it works much more effectively especially with lambda, DocumentDb, RDS, & Dynamodb. Review collected by and hosted on G2.com.

I don't see any major drawbacks or blockers when using AppSync, So I don't have many complaints about it. Anyhow, I feel like usage of this might hold our solutions more into the AWS ecosystem. Review collected by and hosted on G2.com.

The ease of development and testing that AWS provides is spectacular. One can get a prototype out the door quickly and efficiently and then move onto testing in rapid order. Review collected by and hosted on G2.com.

Long-running queries force one to go down the session workaround in order to get everything to work as expected. However, that is a pretty simple task and an understandable limitation. Review collected by and hosted on G2.com.

AWS AppSync makes creating a GraphQL API server (using an existing schema/creating one through the wizard) such a breeze that it can be in a couple of mins. It provides a single pane of glass (API server) abstracting the data from multiple AWS Products like ElasticSearch, DynamoDB. It gives the flexibility to change the backends without impacting the API contract. Any application (iOS/Android/Javascript) can be integrated with AppSync easily using AWS Amplify CLI The editor it provides is a good playground for trying out the queries and supports good auto-completion, and can browse through the GraphQL schema for reference.

Haven't seen any downsides yet but feel the learning curve is more considering it requires to be familiar with other AWS database services for integrating with AppSync. Review collected by and hosted on G2.com.

AWS AppSync enables the creation of APIs to access and combine heterogeneous databases. Multiple data sources can be supported using the API. The API can also access real-time datasets involving unstructured, semi-structured, or relational datasets. The ability to connect with mobile devices and web services is a commendable feature. Local data access is provided when the device is offline and is automatically synced when the device is back online. Also, it supports real-time subscriptions.

The AppSync feature is pricey. The distributed dataset, when accessed, could be challenging to comprehend. The GraphQL feature needs some deep exploration to understand the usage. The caching algorithm is not a straightforward feature. Review collected by and hosted on G2.com.

App Sync combines data from databases, APIs, and other backend systems into a single GraphQL endpoint. Review collected by and hosted on G2.com.

User must have knowledge of data sources that app Sync is going to combine. There a learning curve involved. Debugging can be challenging if app Sync is not configured properly. Review collected by and hosted on G2.com.

AppSync, paired with AWS Amplify, allows you to create and iterate a scalable backend solution very quickly. While using this in an Amplify-powered project, we were able to pivot multiple times while still using the same codebase and same architecture patterns. AppSync's authentication options with Cognito (user & group-based access control), IAM (for accessing AppSync from other AWS resources), and API key access (for unauthenticated users to access data) is perhaps the most powerful feature. Review collected by and hosted on G2.com.

There's a few key downsides to be aware of before committing to AppSync. There is a compiled schema size limit of 64KB, which is not very much space if you want to have granular security permissions. If you aren't familiar with graphql, it may also be difficult to wrap your head around some of the access patterns, and because of some key limitations in dynamoDB there are some typical access patterns and queries that can be difficult (specifically, constucting simple M2M and 121 queries). The only substantial issues I have run into ended up being in my lack of understanding in how it functions. AppSync is in use in production for a multi tenant application, with complicated and granular user and group based access controls. Review collected by and hosted on G2.com.

AppSync is extremely useful and reliable GraphAPI and it handles the security aspect as well. It ensures users are correctly calling the API and handles error cases really well. Review collected by and hosted on G2.com.

It could be a little chaotic in its features and continuous references to documentation are necessary. It is sometimes also prone to hanging and indefinitely becoming non responsive. Review collected by and hosted on G2.com.

The most thing I like in AWS AppSync is it makes me able to create GraphQl API Services and it only takes a few minutes to create it. I can view all data from all AWS services from one API server. Review collected by and hosted on G2.com.

Actually, I have nothing to dislike regarding this product. for me, it's very useful and makes me very satisfied. Review collected by and hosted on G2.com.
