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.
Oracle API Manager is well suited in a business or company that make use of Apis to facilitate access of backend services and data sources by the staff or customers or both. It is also imported in situations where all actions in a system need to be attributed to specific users.

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.
Absence of Role-Based Access. A finer grain control on what type of users can call certain API Endpoints is needed.
Performance with third-party databases isn't as fast as using Oracle Database.
Long learning curve. Although Oracle API Manager provides performance and a vast deal of features, a certain level of expertise is required to effectively make use of them.
Oracle API Manager is much easier to learn and understand then IBM Data Power Gateway and IBM API Connect. We selected Oracle API Manager in our company because to have a good intuitive interface with drag and drop features and because beginners and easily get up to speed to use this tool.
Oracle API Manager supports both REST & SOAP API's.
Secure and attributable connection to back-end services and data sources. In addition to creating API's for querying data, you can also create API endpoints that can manipulate the data in the back-end databases.
Although Oracle API Manager provides performance and a vast deal of features, to start with it is really important you train your people working on development, deployment and administrators to effectively use Oracle API Manager.
