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.

Offers flexible adapters, good scalability but logging can be difficult at times
There is room for improvement in the logging messages. Sometimes, if you put someone new into App Connect, they can abandon it the same day. The logging is really painful. However, IBM has made efforts to integrate with Elasticsearch for logging, so that's an improvement. Overall, the logging can be difficult at times. 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. Back in 2013, I worked with Sonic ESB, and even then, it had CI/CD with Maven. With App Connect, you need to build everything yourself when using tools like Jenkins, Bamboo, or CircleCI. IBM really needs to provide official support for this.

Pros

"AWS has made it easy for developers like me to create and manage GraphQL APIs."
"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."
"It's a powerful application for collaboration. It has many features for customization and integration."
"The most valuable feature is the security."
"App Connect's best feature is that it can be deployed in a container."
"It has an efficient design flow."
"Provides good security features."
"We use IBM App Connect for the integration between the applications."
"Technical support is good."
"One of the most beneficial features is the ability to handle multiple communication technologies, like integrating Kafka flows, which is helpful as other teams heavily use it. Regarding error handling, I initially wrote most of the handling myself. While built-in features for error handling are built-in, it largely depends on the developer. We use a custom solution that catches all exceptions, logs them in a database, and replays them as needed. It has been effective for us for over twenty years."
 

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."
"In AppSync, assigning roles and permissions to APIs is necessary for accessing other AWS services. Automating this task when creating APIs would be beneficial."
"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."
"More connectors could be available for the product as some of the third-party software doesn't have default connectors."
"IBM needs to enhance and have a stronger offering for the event streaming part because this is the future needed for the containerization and the new integration requirement."
"When we do a version upgrade of the system, the platform is kind of complicated."
"They reply in one or two hours at most, but they could be better."
"Updates are constantly delayed."
"IBM App Connect should improve security features."
"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."
 

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."
"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 price could be better."
"IBM App Connect's pricing is high compared to other products."
"App Connect is not cheap."
"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."
"It is very expensive if we want to scale."
