The service is extensive and expensive, and this added flexibility would make it more manageable and less prone to errors.
It's quite expensive, which could be a barrier for some users.
Documentations for the product should include examples of implementation.
Introducing features related to auto governance without manual effort would make the API Manager smarter and more efficient for enterprises with complex landscapes.
Managing the cost of MuleSoft, particularly the billing model based on the number of active cores/threads, has been challenging.
 

Setup Cost

IBM API Connect is costly but feature-rich, with price negotiations possible; smaller firms might prefer open-source alternatives.

Featured Reviews

Shanmugasundaram Shanmuganathan - PeerSpot reviewer
Offers basic API orchestration and provides robust security and governance features
While Azure API Management offers configurable scalability, IBM API Connect relies on Kubernetes clusters. This might seem manual and require defining cluster instances upfront, but it's completely customizable and not on-the-fly scaling. It's completely custom-driven, not on-the-fly scaling, which some may consider cumbersome. Overall, I would rate the scalability an eight out of ten. Almost all applications we've been exposing lately go through this middleware, so it's used extensively. There are around sixty applications directly using it, but six Kubernetes clusters serve those applications. It's heavily used for integration, including system-to-system integration and product integrations. Our usage has been increasing year-on-year based on our needs.

D.Rajesh Kumar - PeerSpot reviewer
Improved Integration Efficiency and Potential for Further Enhancements in Monitoring and User Experience
The policies in MuleSoft API Manager are significant features. We get the policies by default, with more than 25 out-of-the-box policies. If any additional requirement exists specific to the customer, there is a custom policy framework. We can build the policy according to our requirement, and deploy and enable it at the API Manager level to consume across different business groups, environments, or organizations altogether within the platform. Developing the custom policy is not challenging; you just need to follow the custom policy framework to implement. The custom policy and the different levels of SLAs of the API Manager are notable. Regarding the monitoring side of the API Manager, MuleSoft provides substantial monitoring with logs, offering search capability, raw data accessibility, and different subscriptions. With the top tier, integration with third-party platforms such as ELK or Splunk becomes unnecessary because all search capabilities, dashboards, and functional monitoring can be built within the platform itself. This is excellent from the monitoring perspective, and there have been recent improvements focusing on observability. For DevOps, if you want to make your continuous integration and continuous deployment effective, irrespective of the tool, there are options to integrate. For example, you can use the Maven plugin, platform APIs, or CLI to build your end-to-end DevOps cycle.
