"AppSync vs AWS API Gateway"

4/5

What do you like best about AWS AppSync?

AppSync is best service and feature provided by AWS. As this is graphQL, but there is more thing that AWS delivers in AppSync. The subscription feature lets cloud/server connect and send information to users that are connected. Appsync connects you to DynamoDB directly without using Lambda that also reduces billing. Review collected by and hosted on G2.com.

What do you dislike about AWS AppSync?

AWS AppSync has a bug that our organization encountered 4 days ago. It may be a bug that requires fixing. As AWS Appsync recently announced custom authorization that allows doing custom implementation using lambda. It also allows selecting specific authorization on priority. But it did not work with custom authorization as done using following steps.

1. Custom authentication

2. API Cognito Pool

3. API key

In GraphQL we have schema e.g

type Query @aws_cognito_user_pools {

getSites: genericResponse

getToken: genericResponse

}

type genericResponse {

statusCode: Int!

body: String!

}

Following query executed with token generated through cognito_pool and uses aws_congito_user_pools authentication and it does not work and throws 401 error. This issue requires to fix. Review collected by and hosted on G2.com.

Recommendations to others considering AWS AppSync:

Appsync is far the best feature provided and better than APIGateway. Review collected by and hosted on G2.com.

What problems is AWS AppSync solving and how is that benefiting you?

It resolved bi-direction communication between user/cloud, and sometimes used it for push notification. It has reduced the push notification speed used in push sync services. Review collected by and hosted on G2.com.

"Brings the comfort of GraphQL development"

5/5

What do you like best about AWS AppSync?

I like how AppSync helps decompose big building blocks into smaller primitives and removes my need of having a GraphQL server up and running. I can also link a DynamoDB table as a data source directly, without having to write custom resolvers, which is nice. Review collected by and hosted on G2.com.

What do you dislike about AWS AppSync?

The lack of a centralised data access layer is my single biggest issue about using generic index attributes in my data model while using AppSync. The frontend for AppSync is a clunky mess and makes the development process harder. Review collected by and hosted on G2.com.

"Brilliant way to work with multiple data resources in real time using a single GraphQL endpoint"

4.5/5

What do you like best about AWS AppSync?

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.

What do you dislike about AWS AppSync?

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. Review collected by and hosted on G2.com.

Recommendations to others considering AWS AppSync:

It is a brilliant product if you deal with multiple data resources while authorizing numerous requests for a single task. AWS Appsync can be of enormous help if the organizations using it can find a cost-effective way to move to this product . It can wrap your calls to a single secure Graph QL call and can let you keep all the data sources for different purposes without breaking a sweat while extracting information. Review collected by and hosted on G2.com.

What problems is AWS AppSync solving and how is that benefiting you?

I worked with a Fintech startup that were using both SQL for transactions , No SQL databases for quick client profile query resolutions , numerous REST endpoints for payment gateways and regulatory checks and maintaining logs in Elasticsearch. For their business analysis we were fetching data from all these sources and creating dashboards . AWS AppSync was more than handful in fetching data from these diverse datasources in a secure manner and feed it to the live dashboards which were really the life of the management meetings to realize he overall progress of the roduct and the drawn insights to drive actionables for future growth.

""AWS AppSync is the best tool out there""

4/5

What do you like best about AWS AppSync?

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.

What do you dislike about AWS AppSync?

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.

Recommendations to others considering AWS AppSync:

AWS AppSync provides APIs that securely access, combine data and manipulate from abundant sources to make application development easier. Using it made a huge difference in our productivity. AppSync's applications make use of GraphQL to access data. We also reduced setup time. AWS AppSync is a must-have for anyone who works with AWS. Review collected by and hosted on G2.com.

What problems is AWS AppSync solving and how is that benefiting you?

AWS AppSync uses GraphQL APIs to help our teams build apps and services. AWS APP Sync is useful for data synchronization with any external AWS application. It's fast-moving and agile. Using AWS App Sync, we feel much better about our data security. I was doing a lot of front-end development with it. Review collected by and hosted on G2.com.
