Ease of creating APIs with ongoing updates needed for automation
AWS has made it easy for developers like me to create and manage GraphQL APIs. The ease of use is a main advantage, allowing even beginners to start from scratch and learn through AppSync. Before AWS, developing and managing APIs was quite complex. AWS provided AppSync, which assists developers and startup founders. Startups blooming everywhere benefit from this service, welcoming those who lack prior knowledge. When working on AWS, I notice that Amazon regularly implements new features. For instance, with the Lambda service, AWS is transitioning from an old editor to a new one. Similarly, AppSync frequently introduces updates and changes. This trend is making the user interface more accessible, even for individuals without a technical background. Additionally, the cost is attractive, as AWS operates on a pay-as-you-go basis. These factors make AppSync both easy to use and cost-effective.

Cloud workflows have accelerated integrations and now demand better debugging and DevOps support
IBM App Connect provides many features, but there are several areas for improvement. Better debugging and observability would help us track any single transaction end-to-end across steps and connectors. Features such as a step-by-step line view and one-click download for flow execution would be beneficial. Improved CI/CD pipeline and GitOps experience would be valuable. The team wants flows as code and predictable promotion across development, test, and production environments. Stronger native Git integration, export-import functionalities, and first-class pipeline templates like Jenkins, GitHub, and Azure DevOps would be beneficial. More cloud-native, lightweight runtime options would be very helpful. Connector reliability and consistency need improvement because some connectors feel more mature than others, and version changes can break mapping. Pricing and licensing clarity is important because the licensing is complex and can slow down adoption and planning. Some improvement areas include handling very complex structures that the platform currently does not support. Improvements on the DevOps side, particularly providing templates, would be beneficial. The platform is somewhat expensive and hard to predict in terms of cost. Debugging features need to be provided. For CI/CD, the flows are not truly accurate and need improvement.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Support for multiple data sources and formats is a fantastic feature."
"AWS has made it easy for developers like me to create and manage GraphQL APIs."
"Provides good security features."
"Because it has a graphical developer interface, we can quickly develop solutions that are connecting to anything on the cloud, without having to build those connectors ourselves."
"IBM App Connect definitely saves a lot of time, approximately 50 to 60%, and based on the time savings, we can reduce the number of employees needed and save money on reduced resources."
"The most valuable feature is the security."
"The most valuable feature is the user-friendliness of the application."
"The most valuable feature for me is the availability of the adapters, which are already made out of the box."
"It has different type of interfaces that can integrate with companies."
"When using IBM stacks, IBM App Connect is suitable and integrates well with other IBM products like WebSphere."
 

Cons

"Moving to other clouds is impossible without significantly rearchitecting your applications."
"In AppSync, assigning roles and permissions to APIs is necessary for accessing other AWS services. Automating this task when creating APIs would be beneficial."
"The integration with HR systems could be better."
"In the next release, I would like to get some quality connectors."
"The platform is somewhat expensive and hard to predict in terms of cost."
"It is not easy to deploy. It requires someone with a high level of knowledge in the solution to deploy it, not just anyone can do it."
"Critical issues are resolved quickly by technical support, but there is a delay in response to items related to the product, deployment, or low production environments."
"The interface could be better."
"The setup time for App Connect could be improved."
"IBM App Connect is scalable. From the administration side, they need to improve the RBAC model, as well as the clustering of this product. It will be good if we can start up the cluster, via IBM Connect Console. Some other products like MuleSoft, are providing this type of administration. MuleSoft is easy to use and user friendly."
 

Pricing and Cost Advice

"Licensing fees are paid on a monthly basis, and it is a pay-as-you-go model."
"IBM App Connect's pricing is high compared to other products."
"The cost depends upon the consumer."
"It is very expensive if we want to scale."
"The price could be better."
"The licensing cost for IBM App Connect is very high."
"The solution's pricing isn't cheap, but you can get good discounts based on your competitive deal."
"Initially, App Connect was quite expensive because the cost was based on the number of processors we used. However, it's now based on containers, which means we can be more specific about our consumption and get a better price."
"App Connect is not cheap."
