An Introduction to API Management

In technical terms, API management pertains to the API development, operations, safety, and distribution as per the industry’s best standards and scalability for a product or business. It’s done to ensure that the APIs are serving their purposes and helping business ventures as required.

API management tends to alter or modify as per the organizational needs. However, API security, monitoring, and version control are its 3 attributes that your team cannot overlook while creating a strategy for using and improving the API successfully in the long term.

The Concept of a Gateway API

A gateway API is important as it makes all sorts of API administration effortless. It stands in the midway for API and the targeted application. APIs are transported from the gateway first to reach the destination i.e. the app. 

Gateway authorizes the APIs and directs them to the relevant services. While this authentication and API exchange happens, the gateway decodes versatile API protocols and shows the right application service way to every request. Gateway sanctions the APIs and guides them to the relevant services.

Deploying a gateway brings multiple perks to the developers. For instance, software coding is reduced for both the APIs and services. Keeping response time and service requests latency is effortlessly achieved. Gateways advance its security by centralizing the overall task of management. 

Developers have to keep the API gateway update process straightforward and light so that no hefty burden on CPU gateway is exerted. Doing so warrants the conventional functioning of gateway APIs during the changes.

Gateway implementation simplifies API management at multiple stages. But, if it’s not handled properly, multiple bottlenecks can hinder development. For instance, the system can be overflowed with API requests.

What Makes API Management a Compulsion for Today’s Scenario?

APIs carry business-critical data and make complementary assets accessible to the world via web/phone applications. They are useful for digital operations related to a business. However, when lacking attention, the usage as well as up-gradation of APIs suffer, hindering their ability to be secured, scale, and grow.

It’s essential because:

  • Strategically managing the API results in the seamless exchange of traffic between backend to front-end systems. 
  • API governance - a crucial management step - deals with generating a unified experience for patrons. With its help, API lifecycle, discoverability, and reusability can be tracked and managed. This information ensures each API instance is fulfilling its purposes right.

API management platform 

Seeing the power of automation, managing API has also been handed over to API management platforms or software. Using such platforms, businesses can trim down the efforts, time, and money invested in maintaining the product as well as its API.

One such satisfactory and potent platform comprises:

  1. Developer tools 

Every reliable API management platform features one or many API developers tools that can take care of jobs like API generation, testing, debugging, document generation, API usage governing, and API deployment. Mostly, a highly visually rich API development ecosystem is generated by these developers' tools to aid the API code generation. 

  1. Management Core

It handles the API lifecycle, letting development teams track everything from API generation to its going out of service. Management Core also offers support resources for API creation, configuration, testing, and maintenance.

  1. API Gateways

For effective data trade, every efficient API management platform should be equipped with a server for request authorization, administering facts to the back-end team, and transporting the responses to the requester. It’s known as API Gateway. 

Gateways act as a bridge between all the connected systems and services in order to pass on the fundamental information seamlessly. It bears the responsibility of intensifying the API efficiency and reducing downtime. The gateway is also in charge of tasks like schema validation and data transfer between the source to the destination. 

  1. Databases

Data security and fetching data from relational or non-relational databases are a few crucial things when it comes to application security. So, interaction with databases through APIs must be secure too. API calls monitoring and detail recording can help in this. With this, any inconsistent or incorrect operation can be caught and needed actions can be taken in time.

  1. Reporting and analytics 

Tracking API development, usage, deployment scenario, and utility are decisive API management factors. With reporting and analytics components, an API management platform can watch over all these API-related metrics like API volume transferred, time taken in the API development, and data objects returned. 

Usually, a dashboard features reporting and analytics details. Such continual API monitoring helps in API performance optimization and guides a business at each step of API management journey.

Microservices and API Management

These are two key ingredients of successful and innovative application development necessitated by every business. When combined together, Microservices and API Management are called cloud-native application development approaches. 

While this approach is time and cost-saving, it’s not free from challenges. Think of this example: It’s very tedious to break huge and complex systems into smaller yet equally effective components. There is a need of having a constant connection between all these smaller data resources and components. 

APIs can be helpful in this regard. In the process, API management makes sure that an adequate discovery mechanism for microservices can be done and the user documents, explaining the use case scenario of microservices, are offered via the developer portal.

Security of microservices demands a unified approach that depends on the APIs. To begin towards the same, external-facing services can have a separate security setup which is different from the internal ones. 

If the API is not used for crucial tasks then the API key is enough. Microservices, using critical APIs, use OAuth for security.
