that their APIs are consumable, secure, and managed?

API management is the process of building,

across an enterprise and multi-cloud setting.

More than just a place for these APIs to live,

API management offers a centrally visible, scalable platform,

where enterprises can share and socialize their APIs

and enforcing associated security policies.

A popular way to talk about what an API is is by using a restaurant metaphor.

So, let's think of a kitchen at a restaurant.

There's what ingredients the kitchen uses?

But as a diner, all you need to know is what is on the menu.

So, in this analogy the kitchen would be an application or service,

And, once the diner knows what they want,

it's a way to interface with the application,

So, the user would make a request to the API,

some time would pass, and they would get what they asked for back.

is that it is possible to supply information to an API.

as a diner, you could supply some raw ingredients to your server,

and the server could use that in the kitchen

to affect what dish is coming back out to you.

So, let's talk about a retail application where APIs are used

to kind of give a sense of how they're used in microservices.

So, let's consider a contact information database,

and then that is going to expose information through an API,

and then for front end, let's say we have a shopping cart,

and that will use our inventory, but not necessarily a contact information API.

Let's have a check out which will need both,

which might only need contact information,

So, these are consuming information from our backend services,

transforming it, and then exposing those results through their own APIs,

and these APIs up top are exposed to the public.

So, it's possible, too, to expose your backend service to the public

So, if you wanted to create an API that lets your

users change their contact information directly, you can definitely do that.

how is that going to improve upon what's already happening here?

So, there are 4 core elements of an API management system.

So, the first one is going to be the gateway.

So, the gateway sits between the web client

and the systems and services that it's connected to.

So, the gateway is going to handle all routing requests.

It handles a data composition and protocol transformations.

In addition to that, the gateway handles security authentication and authorization,

and it can use state-of-the-art security like OAuth, OpenID, JWT.

The gateway also handles data aggregation,

so it receives one request from the web client

but then it will aggregate that and send it back as one response.

The next part of an API management system is a developer portal.

So, the developer portal is a self-service hub

where developers can go to browse access and share

So, if an API definition is like our menu,

and this is going to really streamline communication between teams in an enterprise,

so you can imagine across an enterprise there could be hundreds or even thousands of APIs.

So, being able to centralize access to that is invaluable.

So, we can think of an API as a building block.

If you make an API and expose that for other people to use,

and they incorporate your API into their system,

they're trusting you to keep your part of their system healthy.

So, the life cycle manager will help you build, test,

on board, manage, and eventually retire your APIs.

You can manage your APIs every step of the way,

API management solutions use synthetic monitoring

to watch each API's availability, response time, and overall health.

You can also incorporate analytics solutions

diagnose and troubleshoot integration issues as they arise
