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.

Transforms data efficiently and navigates licensing challenges with ease

The transition between version 12 and version 13 presents some challenges. While version 12 had approximately 10 features, version 13 includes around 200 features with cloud platform compatibility. The learning curve for developers moving from version 12 to 13 could be smoother. When using new components, better context explanations would be beneficial. In version 13, accessing new features requires connecting through a web browser, which can be challenging to understand. The explanation of new features could be more user-friendly.

"It's a powerful application for collaboration. It has many features for customization and integration."

"It can handle API conversions with mapping and transformation rules, simplifying the development process."

"The most valuable feature is the security."

"The most valuable feature is the user-friendliness of the application."

More IBM App Connect pros

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 setup time for App Connect could be improved."

"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."

"In the next release, I would like to get some quality connectors."

"The product should improve its support."

"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."

"The installation of containers could be simplified, as it currently requires a senior-level installer."

"Plugins for the repositories are difficult to find."

"More connectors could be available for the product as some of the third-party software doesn't have default connectors."

More IBM App Connect cons

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."

"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."

"It is very expensive if we want to scale."

"The price could be better."

"IBM App Connect's pricing is high compared to other products."

"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."
