API Management: Flexibility, Security, Analytics

Key Points

  • API management adds crucial flexibility, security, and analytics to modern API architectures, making it a must‑have component for both enterprises and startups.
  • APIs can be split into two categories: **service APIs** that directly access systems of record and **interaction APIs** that sit on top of service APIs to enable higher‑level operations.
  • An API gateway acts as the unified entry point for all consumers, allowing you to enforce policies, protect backend services, and avoid direct coupling between clients and internal APIs.
  • By publishing standardized OpenAPI/Swagger specifications in a developer portal, you enable self‑service onboarding, consistent documentation, and easier governance of both service and interaction APIs.

0:00Node.js, GraphQL, Spring Boot, Golang 0:05There's so many options we have, as technologists, 0:08to build today's modern APIs. 0:11For today's topic I want to talk about why you should consider having 0:15API management in your architecture. 0:18Hello, my name is Jamil Spain. 0:20I'm a brand technical specialist   for the Cloud Pak for Integration 0:24in the U.S. Financial Services market, 0:27and when it comes to API management,  I want to focus on three quick areas 0:32that are really my top three when I talk about this topic. 0:35One is injecting some flexibility in your architecture. 0:39The second is security. 0:40And, more importantly, the analytics that you're going to get in return, 0:45So, I ll explain more here. 0:46Now, before we get started, I do want to talk and level set 0:50on some common terms that come up   when we talk about API development. 0:54Now, there are two major types that I like to classify APIs. 0:59The first is service APIs. 1:04Now, I consider service APIs anything that directly talks to a system of record. 1:11Whether you're an enterprise developer or a 1:14general startup developer, you're making   your own project here, 1:18you always want to protect these APIs. 1:21These are generally your strongest assets here. 1:24The second type are interaction APIs. 1:31Now actually, anything that's not a service  API, I consider to be an interaction API. 1:39When I start a project out, I generally start with  my service APIs, and then I start development on 1:45these interaction APIs. They may actually call  these service APIs , but let's take a look at that 1:51word. There's one key piece here. That root of  that is interact , so it is generally making some 1:58interaction on top to facilitate some type of  operation that you want to programmatically do here. 2:04This is what starts us off at our first  point here: flexibility in the architecture. 2:10Now, you have consumers who are going to be using  your APIs. In API management, one major concept 2:18is having an API gateway that you have. So,  your users, consumers of your APIs, will 2:24always interact with the API gateway when they  want to consume your APIs. 2:29Now, the job of the actual API gateway 2:34is to perform the interaction layer, API layer, there for the most purposes. 2:40Now this is greatly differs if you don't have  API management. 2:44Users, consumers of your APIs, may directly be talking directly to your APIs, 2:49but this puts a layer in front. 2:51One of the first things 2:52that gives you the greatest flexibility  is I get to standardize on an interface 2:58you know, denoted and documented through open API  swagger specs of course, through those YAMLs there, 3:04and published in a developer portal so they can easily self-service and get on board to using the APIs, 3:11but the most important thing is, they define, you know, they're going to get a standard 3:17definition of these APIs. 3:19Now, what actually happens on the other side 3:22for your services that you're running, and I'm   going to do these little database icons here to 3:28imitate the API that you're writing here, it could  actually go to one service or it could be multiple 3:35interactions, invocations to these APIs, and  more of a I've actually done some scatter 3:41gather patterns where I want to hit three services  and build a response that goes back to the user, 3:46the consumer. 3:48Why is that important? 3:49Well, we all know that with all those technologies that 3:53I mentioned at the beginning, 3:54we want to always be in a place that we can feel free to innovate, 3:59refactor, explore new technologies. 4:01Especially in this day and time of container architecture 4:04and cloud native, it is very easy to now free yourself and try many, many new technologies here  as well. 4:11If you're providing a singular URL to  your users that, without API management, you have 4:17to always be cognizant that, "Hey, I have to always  be able to update my users to the newest thing." 4:23Now, whether that's your new latest startup,  or your new latest enterprise application, 4:28that may be very critical very hard to do in some  perspectives here. 4:33But by having API management in, it gives me the flexibility 4:37to do my own innovation inside. 4:39The interface that I, 4:41that I give to my users externally doesn't   always have to directly mirror the architecture 4:49that I have inside, so I m free to innovate  there as well. 4:53Second, while this occurs, 4:55I have an opportunity to implement some security here. 4:59Each consumer of my APIs when they come up 5:02APIs are generally part of the API management  solution is the APIs have to be published in 5:08some type of usually a self-service developer  portal, and they're going to get assigned a client 5:15ID and secret. 5:19This is a great way of identifying and designating that I know 5:25who is registering their applications and who's  using the APIs there as well. 5:30On top of that, 5:32the second most important thing with security, is  I get to implement an SLA with rate limiting. 5:45Now, this is very, very, very critical because  it gives us a way to kind of conserve the APIs, 5:52the usage of the APIs, that are coming. 5:54I can leverage it to make a service level agreement here 5:58on how much you can use, or if  you want to actually get into monetization, 6:03getting higher tiers, publish a freemium tier, and  then have more higher tiers that you can do. 6:10You can all facilitate this. This is usually built  into every API management solution. 6:17Without this, you'll have to code and try  to implement these parts yourself. 6:22Lastly, analytics. 6:24I love these because it helps you get to know how  much your APIs are being used. 6:34And once you have users subscribe, 6:37you have this in place, I'll be able to know who are my most important users of my APIs. 6:43Without API management here you really  don't have a strong indicator of how much people 6:49are using, how many errors you're getting back,  what's the performance, what's the latency. 6:54So, all these decisions are really hard to - you're  kind of guessing that as well. 6:58Now for you, the organization making the APIs, one of my best things here as well is: 7:05what do we work on? 7:11In today's culture we are a data-driven society,  and this will clearly give us the metrics to say, 7:19we need to devote our time to this particular API  set , because this we have the data to back it up, 7:25that this is what people want, is what they're  using here as well. 7:29So, with this, let's to recap here. 7:32API management is important for the  mere fact of the flexibility it gives you in 7:37your architecture, the security options you have  at your fingertips to implement 7:42and, also, the analytics you get back. 7:45Thank you for your time. 7:47If you have questions, please drop us a line below 7:50and, if you want to see more videos like this in the future, 7:54please like and subscribe.
