Azure API Management vs. SAP Integration Suite

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.

In our case to have a such a poweful middleware in the cloud, give us a lot of benefits such as maintenance and support. In the integration part to be able to connect SAP and Non SAP applications makes SAP Integration Suite a good investment when our master data in this case is in S4HANA. Less appropriate is that sometimes the updates in production tenant failed and they have to downgrade or repair the issues. Affecting the usage of the tool. I guess SAP team have to be more aware of performing the changes and tested well on development environments and then when they know for sure that is the correct way to go with the update put it in production.

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

Incentivized

• Enhanced API management features that allow now the integration with a multitude of data feeds and rating agencies
• Immediate evaluation of potential issues and configurable thresholds and automatic notifications.
• The application will monitor all aspects of compliance and update them automatically for several jurisdictions at time

• 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.

Incentivized

• Provide more pre-built integrations to use within SuccessFactors or other modules instead of everything having to be custom built
• Support is unable to provide advice on custom builds so you often have to engage a 3rd party partner
• Works best when you have the functional and technical teams working together. Otherwise, the system is too technical for a functional user to create integration and a technical user not always understand the functional perspective

It is in place, our system integrators are familiar with it, and it fits into the ecosystem. A better user interface, flow build and debugging experience would see it grow, many technical staff do not enjoy using it for this reason, however it is quite capable and powerful behind this one shortcoming.

Incentivized

The user interface is messy and not intuitive. It has a steep learning curve, and flows developed around are easy to make a mess with layout and can be difficult to follow. The debugging is also quite difficult, it takes some time to figure out how to follow the flow and examine data. Error handling is also difficult and not intuitive, it is better to let some errors leak and monitor through ALM.

The support for SAP Integration Suite is satisfactory. We leverage SAP support through our manage services partner. So far, we have not had many major issues. One concern, to make our rating a ten, would be turnaround time on high priority incidents. SAP Integration Suite drives our key business functions forward. Without a reasonable service level agreement on turnaround, we sometimes find us running into issues running pay, etc.

Incentivized

Work with an SAP implementation partner, if possible.

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.

Incentivized

SAP Integration Suite was already part of our SAP stack, part of Business Technology Platform, with out-of-the-box integration with S/4 HANA transactional and ERP system that we are using as our main back-end. Thus, we are achieving significant Total Cost Optimization benefits or running both solutions on the same platform, hosted on Azure cloud.

Incentivized

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

• In the long run will enable us to undeploy our on premise solution
• As long as integration suite doesn't support all capabilities PO has complete migration is hard
• Will probably be cheaper than our on premise solution when we are completely migrated
