Apache Camel vs. Azure API Management vs. Mule ESB

Message brokering across different systems, with transactionality and the ability to have fine tuned control over what happens using Java (or other languages), instead of a heavy, proprietary languages. One situation that it doesn't fit very well (as far as I have experienced) is when your workflow requires significant data mapping. While possible when using Java tooling, some other visual data mapping tools in other integration frameworks are easier to work with.

APIM is useful for the standard scenarios:

1) Securing your back-end APIs - If you have a legacy back-end web service that has a basic authentication scheme, you can add some additional security by placing APIM in front, and requiring subscription keys. Leverage your existing firewall to ensure only your APIM instance can communicate with your back-end API, and you've basically added a layer of protection.

2) Lift and shift - there are always going to be clients that don't want to update their clients to use a newer API; in some cases you can make a newer API look like an older one by implementing some complex policies in APIM. You can also do the opposite, making older APIs look new, such as making an XML back-end accept both JSON and XML.

3) Centralizing your APIs - if you've acquired another company and want to make their API set look as if it's a part of the larger whole, APIM is an easy way to provide a consistent front-end interface for developers.

If you’re bringing anything into Salesforce you should just invest now into Mule, you will get your money’s worth and find a myriad of uses to build APIs between many other systems. Once you build a component you can easily reuse it as a building block to attach to another source/destination. This makes it easy to ramp up quickly and spread usage of Mule throughout your enterprise. A good value for medium to large companies, but probably cheaper to outsource your job to a consulting firm if you are smaller.

• Camel has an easy learning curve. It is fairly well documented and there are about 5-6 books on Camel.
• There is a large user group and blogs devoted to all things Camel and the developers of Camel provide quick answers and have also been very quick to patch Camel, when bugs are reported.
• Camel integrates well with well known frameworks like Spring, and other middleware products like Apache Karaf and Servicemix.
• There are over 150 components for the Camel framework that help integrate with diverse software platforms.
• Camel is also good for creating microservices.

• Easy commissioning of APIs.
• Great policies to control access.
• Easy mock services for testing.

• It is best suited for Rest API development. Mule ESB uses RAML as an API descriptor which is less complex and easy to understand. RAML is an open standard majorly supported by Mulesoft. Once RAML is developed, it is very easy (a few clicks)to create flows corresponding to the resources defined in the RAML. One can also include JSON schema validation in RAML, and with the use of APIkit router, Mule ESB makes the request validation very easy (it's automatic basically.)
• Mule ESB comes with a large spectrum of community and enterprise connectors. We have connectors for all the major platforms like Facebook, Twitter, Salesforce, SAP, etc. This enables Mule ESB to integrate with the other systems in a faster and more robust way. Mule ESB has many components to fulfill the requirements of each integration (for example batch processing, parallel processing, choice, etc.)
• Mule API gateway is one of the best tools (modules) of Mulesoft's offering. It supports API governance and management very well. One can easily enforce policies on their APIs with API gateway. It enables some of the must-have features in an API solution (i.e. throttling, oAuth, access levels, etc.)
• Implementing a CI/CD (DevOps) environment for Mule ESB is a very easy task. Mule majorly uses MAVEN as its build tool, which in turn makes it best suitable for CI/CD approach. Mule also provides MAVEN plugins for auto deployments to the servers. Mule also has a best Unit testing module which is MUnit. MUnit can be used for both Unit and Functional testing, and it is easy to write and generates coverage reports in various formats.

• didn't work well when our developers tried to transform heavy data sets
• Apache Camel's whole logic is based on java so team needs to have a great skill set in java
• if there are a handful of workflows then Apache Camel's full potential can't be realized

• Lack of robustness is a bit of an issue. Several other providers offer more options and capabilities, but then, they are lacking in interface ease.
• As with anything Azure, pricing is really hard to stay on top of. I always find that you really don’t know what you’re paying for until you get the bill. Having an excellent Azure Administrator can help resolve that.
• Integrating with app services outside of Azure can be a challenge, or at least much more challenging than just using Azure App Services.

• Make sure to not over-engineer shared components. It can complicate development
• Create a roadmap for where you are going - if not, you may miss components
• I suggest getting support, otherwise it could be a difficult learning curve

If you are looking for a Java-based open source low cost equivalent to webMethods or Azure Logic Apps, Apache Camel is an excellent choice as it is mature and widely deployed, and included in many vendored Java application servers too such as Redhat JBoss EAP. Apache Camel is lacking on the GUI tooling side compared to commercial products such as webMethods or Azure Logic Apps.

Azure APIM vs Amazon API Gateway:

1) Azure APIM was a complete package that included a developer portal.

2) We are very Microsoft centric - so the Microsoft product suite aligned very well with our business needs.

3) It was faster and easier to stand up Azure APIM for testing than it was for the Amazon API Gateway.

It doesn't have API . We have to go for another API manager. But in Mule, it has both API manager and ESB

• Very fast time to market in that so many components are available to use immediately.
• Error handling mechanisms and patterns of practice are robust and easy to use which in turn has made our application more robust from the start, so fewer bugs.
• However, testing and debugging routes is more challenging than working is standard Java so that takes more time (less time than writing the components from scratch).
• Most people don't know Camel coming in and many junior developers find it overwhelming and are not enthusiastic to learn it. So finding people that want to develop/maintain it is a challenge.

Incentivized

• We can always think of positive ROI impact on business
• It helps to easily facilitate the design, deployment, and maintenance of our APIs

• Overall a great tool for complex integrations
