  ### 7. AppSync vs AWS API Gateway

**Rating:** 4.0/5.0 stars

**Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.)

**Reviewed Date:** February 21, 2022

**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.

**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.

**Recommendations to others considering AWS AppSync:**

Appsync is far the best feature provided and better than APIGateway.

**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.

  ### 8. Aws AppSync powerful graphql based service

**Rating:** 4.5/5.0 stars

**Reviewed by:** Abhinav J. | Software Developer, Mid-Market (51-1000 emp.)

**Reviewed Date:** June 08, 2022

**What do you like best about AWS AppSync?**

AWS AppSync is good in no. of ways such as 

1. It saves Time
2. It is Highly Scalable
3. It can support Realtime applications
4. It supports for Offline Access

**What do you dislike about AWS AppSync?**

Aws AppSync tho is super useful but has a big learning curve to get started with also debugging is bit tricky here.

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

I am personally using it for my mobile application backend api where we are calling 100s of APIs and AppSync is a very useful tool as it supports graphql.

  ### 9. Brings the comfort of GraphQL development

**Rating:** 5.0/5.0 stars

**Reviewed by:** Harsh M. | Technical Writer Intern, Enterprise (> 1000 emp.)

**Reviewed Date:** December 28, 2021

**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.

**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.

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

We are using AppSync as our data interface where no service talks directly, not even internal services. This helps maintain a consistent interface at the expense of being careful about your VTL resolvers.

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

**Rating:** 4.5/5.0 stars

**Reviewed by:** Shwetank D. | Lead Software Engineer - AVP, Mid-Market (51-1000 emp.)

**Reviewed Date:** December 31, 2021

**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.

**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.

**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.

**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.

  ### 11. "AWS AppSync is the best tool out there"

**Rating:** 4.0/5.0 stars

**Reviewed by:** Al Mubassir M. | Software Engineer, Small-Business (50 or fewer emp.)

**Reviewed Date:** December 08, 2021

**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.

**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.

**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.

**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.

  ### 12. Best GraphQL platform for working with various data source.

**Rating:** 5.0/5.0 stars

**Reviewed by:** Vithushan S. | Co-Founder, Small-Business (50 or fewer emp.)

**Reviewed Date:** September 23, 2021

**What do you like best about AWS AppSync?**

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.

**What do you dislike about AWS AppSync?**

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.

**Recommendations to others considering AWS AppSync:**

We have tried few open-source ETL solutions with the rest APIs as well as some middleware technologies at our organization. But when we started using it we got tremendous benefits on performance. Also, we were able to reduce timelines to set up. So definitely AWS AppSync is recommended.

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

As a software vendor, we have in-house middleware consulting & data pipeline management teams, Where we deal with a lot of source systems and a lot of storage solutions within AWS. That's where AWS AppSync helps our teams to make this task simple by utilizing GraphQL APIs

  ### 13. A fantastic tool for GraphQL api development

**Rating:** 5.0/5.0 stars

**Reviewed by:** JJ J. | Cloud Solution Architect, Enterprise (> 1000 emp.)

**Reviewed Date:** December 28, 2021

**What do you like best about AWS AppSync?**

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.

**What do you dislike about AWS AppSync?**

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.

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

Cloud native GraphQL api development is what AWS AppSync provides with an emphasis upon security at ground zero. Rapid prototyping and allowing frontend devs to access multiple services or dbs only makes everything better.

  ### 14. Create flexible API connecting multiple backends

**Rating:** 4.5/5.0 stars

**Reviewed by:** Naga Kiran K. | Master, Mid-Market (51-1000 emp.)

**Reviewed Date:** November 09, 2021

**What do you like best about AWS AppSync?**

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.

**What do you dislike about AWS AppSync?**

Haven't seen any down sides yet but feel the learning curve is more considering it requires to be familar with other AWS database services for integrating with AppSync.

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

To Provide a single API endpoint for web application abstracting the multiple backends

  ### 15. Great sync tool by AWS for data consolidation.

**Rating:** 4.0/5.0 stars

**Reviewed by:** Giridhar P. | Sr. Data Engineer, Enterprise (> 1000 emp.)

**Reviewed Date:** September 24, 2021

**What do you like best about AWS AppSync?**

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

**What do you dislike about AWS AppSync?**

The Appsync feature is pricey. The distributed dataset, when accessed, could be challenging to comprehend. GraphQL feature needs some deep exploration to understand the usage. The caching algorithm is not straightforward feature.

**Recommendations to others considering AWS AppSync:**

Good product to consider if your applications are hosted in AWS. The integration of data from different sources on AWS could be best established using App sync.

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

Using AWS APPSync, i was able to integrate mySql, S3 and Athena layer as a consolidated layer. The data distributed across these 3 layers were successfully unified for data analysis. The comparison of data across the different sources was made simple with the use of API. Using GraphQL query, the data was structured in a legible format from the server.

  ### 16. AWS AppSync - combiner

**Rating:** 4.0/5.0 stars

**Reviewed by:** Babu R. | Senior Architect, Small-Business (50 or fewer emp.)

**Reviewed Date:** November 30, 2021

**What do you like best about AWS AppSync?**

App Sync combines data from databases, APIs, and other backend systems into a single GraphQL endpoint.

**What do you dislike about AWS AppSync?**

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.

**Recommendations to others considering AWS AppSync:**

One must understand the challenges of integrating different types of data sources that are being combined into graphql db. That will help in debugging when something doesn't work as expected especially in data querying.

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

Currently I use app Sync to combine data from SQL, nosql, neo4j db, http logs, and aggregated data into one large graphql db. This large graphql db can be queried offline to support custom query.

  ### 17. Create powerful GraphQL endpoints with AppSync

**Rating:** 5.0/5.0 stars

**Reviewed by:** Forest K. | CTO, Small-Business (50 or fewer emp.)

**Reviewed Date:** September 15, 2021

**What do you like best about AWS AppSync?**

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.

**What do you dislike about AWS AppSync?**

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.

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

The key advantage of AppSync (and the only reason you should really consider it at all) is it's integration with cognito. By leveraging cognito with AppSync and other services, you can focus more on building YOUR business logic instead of a bunch of boilerplate authorization and permissions code.

  ### 18. A user friendly AWS best

**Rating:** 4.5/5.0 stars

**Reviewed by:** Varsha R. | Incident Response Consultant, Small-Business (50 or fewer emp.)

**Reviewed Date:** January 06, 2022

**What do you like best about AWS AppSync?**

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.

**What do you dislike about AWS AppSync?**

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.

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

Easy API calling and simple Graph and Map generating achieved successfully. It is also a part of the AWS bundle making it very easy to integrate with other AWS features.

  ### 19. A Quick Review for AWS AppSync

**Rating:** 5.0/5.0 stars

**Reviewed by:** kareem e. | Software Test Engineer, Mid-Market (51-1000 emp.)

**Reviewed Date:** December 26, 2021

**What do you like best about AWS AppSync?**

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.

**What do you dislike about AWS AppSync?**

Actually, I have nothing to dislike regarding this product.
for me, it's very useful and makes me very satisfied.

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

AWS AppSync is very useful in data synchronization with any other AWS application. And With AWS AppSync our team is able to develop and build applications and servers very smoothly.

  ### 20. Intuitive APIs with minimal work

**Rating:** 4.0/5.0 stars

**Reviewed by:** Verified User in Computer Software | Mid-Market (51-1000 emp.)

**Reviewed Date:** November 07, 2021

**What do you like best about AWS AppSync?**

Normally, it takes a lot of work to scale a GraphQL API -- especially in an enterprise environment. With AWS AppSync, we've been able to significantly reduce the amount of work required to scale our GraphQL API. Similar to Lamda, AppSync takes literally minutes to set up. Almost immediately, you have a production ready API to interface with yourdisparate services (such as DynamoDB and Lambda). Of course, you basically need to commit to the AWS ecosystem... but if you do, then AppSync is a no-brainer. We've wasted so much time in the past setting up GraphQL infrastructure, but not any longer -- give it a try.

**What do you dislike about AWS AppSync?**

By far, the thing I dislike the most is thr cost per request. Like AWS Lamda, if you're not careful, then your monthly AppSync bill can grow out of control. Of course, this only applies when your handling millions of requests per month. If you can keep your requests under a few million per month, the cost isn't very high.

The nerve wracking part is that, if there's an unexpected flurry of API requests, your bill can grow completely unexpectedly. I've seen this before in environments where an automatic retry was issued every few seconds. This led to millions of extra requests per month. Fortunately, AWS has great customer support, and can forgive certain instances like this. Bit it's important to be careful.

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

AppSync saves us so much time. It allows us to build an API for our distributed architecture in a matter of minutes. We no longer have to have dedicate hours to debugging GraphQL configs or wrestling with nginx. The auto scaling is a game changer.

  ### 21. create responsive, collaborative mobile and web applications with other developers.

**Rating:** 4.0/5.0 stars

**Reviewed by:** Verified User in Education Management | Small-Business (50 or fewer emp.)

**Reviewed Date:** October 16, 2021

**What do you like best about AWS AppSync?**

AWS AppSync has well-optimized data aggregation solutions from various sources and exposes it as a GraphQL API. AWS AppSync is available on AWS. One of the best things about AppSync is how much better it performs when compared to other similar solutions in that row.

**What do you dislike about AWS AppSync?**

AppSync doesn't appear to have any major drawbacks or obstacles in my opinion, so I have no issues with it. As a result of this, I believe that using it will further integrate our products into the AWS ecosystem.

**Recommendations to others considering AWS AppSync:**

Our company has experimented with a few open-source ETL solutions utilising the rest APIs and middleware technologies. Once we started using it, however, we noticed a significant improvement in performance. We were also able to shorten the time it took to get everything up and running. As a result, AWS AppSync comes highly recommended.

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

we have in-house middleware consulting and data pipeline management teams that deal with a wide variety of AWS source systems and storage solutions. That's where AWS AppSync comes in handy, as it uses GraphQL APIs to make things a lot easier for our teams.

**Rating:** 4.5/5.0 stars

**Reviewed by:** Kristy C. | Technical Business Analyst/Product Owner - Yellow Hammer BSA & Fraud, Enterprise (> 1000 emp.)

**Reviewed Date:** September 28, 2021

**What do you like best about AWS AppSync?**

I like how easy it is to run a schema; even someone with virtually no development experience can do it.

**What do you dislike about AWS AppSync?**

I think that while using AWS, Java is slightly less user-friendly than mobile workflows. I am not sure if its is because JavaScript is more towards application support and not built-in, but I do believe that development could make some enhancements.

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

The data loader has been very helpful for our organization since we are pulling in data from multiple sources and needing to consolidate/merge them. Its very helpful at realizing any conflicts that come about from merging, and it provides excellent resolution capabilities.
