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

"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."
"Technical support is good."
"It has an efficient design flow."
"Provides good security features."
"It has different type of interfaces that can integrate with companies."
"App Connect's best feature is that it can be deployed in a container."
"I like the adapters. The adapters help us achieve scalability. If you want to connect to SAP, there's an adapter. Salesforce? There's an adapter. You want to connect to another system? There's likely an adapter for that."
"The most valuable feature is the security."
"We are using App Connect because it's a more comprehensive solution that can handle many projects."
 

Cons

"In AppSync, assigning roles and permissions to APIs is necessary for accessing other AWS services. Automating this task when creating APIs would be beneficial."
"Moving to other clouds is impossible without significantly rearchitecting your applications."
"The installation of containers could be simplified, as it currently requires a senior-level installer."
"The licensing cost for IBM App Connect is very high."
"The product should improve its support."
"The user interface of IBM App Connect can be a little bit more user-friendly, I would say because the first-time developer is onboarded while using IBM App Connect, he or she may get a little intimidated or daunted looking at all the options available or the pipelines, et cetera."
"One more important point is that if IBM improves its CI/CD capabilities, it will make a big difference. Right now, I have to create my own CI/CD setup from scratch for every client, which is inefficient."
"Finding developers for the product is difficult since it is a niche solution. I know the OpenShift environment is running well for the microservice environment. We had some issues with the other environment we tried to implement. It can be easily implemented internally, but we have some problems in practice."
"IBM App Connect should improve security features."
"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."
 

Pricing and Cost Advice

"Licensing fees are paid on a monthly basis, and it is a pay-as-you-go model."
"The price could be better."
"It is very expensive if we want to scale."
"App Connect is not cheap."
"IBM App Connect's pricing is high compared to other products."
"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 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."
"The cost depends upon the consumer."
