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

Pros

"AWS has made it easy for developers like me to create and manage GraphQL APIs."
"Support for multiple data sources and formats is a fantastic feature."
"We use IBM App Connect for the integration between the applications."
"When using IBM stacks, IBM App Connect is suitable and integrates well with other IBM products like WebSphere."
"This latest version is very scalable, flexible and user-friendly."
"It has an efficient design flow."
"The solution is fast and supports Open UI 3.0 certification."
"The beauty of IBM App Connect is that it provides end-to-end middleware."
"There is a friendly interface for configuration, and integration is made easy."
"The solution is very fast-paced when it comes to making things right. We can quickly download what we need if we need any app migrations for our software business. We can download it plenty of times when we need to use it. It gives us very high speed for delivering any development."
 

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."
"When we do a version upgrade of the system, the platform is kind of complicated."
"IBM App Connect occasionally crashes for various reasons, requiring problem-solving intervention."
"The addition of string functionality would be a benefit, particularly in the ESQL space that IBM already uses internally."
"I've been using IBM App Connect for about twenty-five years, and while I like it, there are some areas for improvement. The trace policy is ridiculous, and the biggest issue is the cost—it's expensive. People would use it much more if the price point weren't so high."
"The interface could be better."
"The licensing cost for IBM App Connect is very high."
"More connectors could be available for the product as some of the third-party software doesn't have default connectors."
"IBM App Connect should improve security features."
 

Pricing and Cost Advice

"Licensing fees are paid on a monthly basis, and it is a pay-as-you-go model."
"The cost depends upon the consumer."
"IBM App Connect's pricing is high compared to other products."
"App Connect is not cheap."
"It is very expensive if we want to scale."
"The licensing cost for IBM App Connect is very high."
"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."
"The price could be better."
"The solution's pricing isn't cheap, but you can get good discounts based on your competitive deal."
