If APIs are a central part of your integration strategy, you need to make sure the service is reliable, secure, and documented. This is where API management tools play a vital role for an organization. They provide the means to expose your API to external developers in an easy and affordable manner.
API management features
API management services come with a lot of features. The main focus is to make designing, deploying, and managing an API easier, as well as to ensure that it is safe, secure, and functional. Some of these tools facilitate integrations, transformations, or API orchestrations. Ideally, API management service should cover most of the below features:
- Analytics and statistics: It is critical to understand how people use your API and get insights for your business.
- Documentation: One of the most common problems developers have is figuring out how an API works. Development time is too precious to waste in trial and error of an undocumented API. An API management service has to provide an easy way to read the documentation and enable developers to try it before purchasing. In some cases, it is even possible to provide interactive documentation. Simplicity and usability are the key.
- Developer engagement: Engaging with your API consumers, developers, or partners is important. Getting an easily accessible developer portal will significantly facilitate on-boarding.
- Sandbox environment: This feature will increase both the value of an API and its adoption rate. What’s better than being able to develop andtest your code?
- Deployment: Deployment should be flexible and support public or private clouds, on-premises implementations, or combinations.
- Security: APIs carry sensitive data, so it is important to protect the exposed information. The service has to at least provide identity and access management for users and developers.
- Traffic: Traffic managementand caching abilities should be provided.
- Monetization: They should provide the capability to monetize your API.
- Support: Legacy systems should be supported by your API.
- Availability: Should be available, scalable, and redundant. An API environment can become demanding, and the service should be able to deal with any kind of errors or temporary traffic spikes.
Yes or no to proxy?
Vendors in API management provide numerous solutions across the above categories, but that does not mean they support everything. Solutions are implemented in three different ways: proxies, agents or hybrid approach.
- Proxy: The solution resides between the customer and their users and the traffic goes through them. Proxies provide caching capabilities and protection of customers’ back-end infrastructure from traffic spikes. The main criticism they receive is that they increase the cost and bring up privacy and latency issues. Apigee, Mashape, and Mashery are examples of such implementations.
- Agents: These are plugins that integrate with your server. They do not get in the way of the API calls like proxies do. As a result, they do not introduce network latencies or third-party dependencies. On the other side, features like caching are not easy to implement. 3scale is an example of such implementation.
- Hybrid approach: This means you may get both an agent and a proxy. For example, you may want to use a proxy for the caching and the agent for authentication. Companies like Apigee or 3scale that were mentioned previously are also moving to hybrid solutions.
