API Management enables you to create compatible and modern API gateways for enduring back-end services. API Management helps organisations to publish their APIs to external partner as well as internal developers to unlock the potential of their data and services. Business users are looking everywhere to increase their operations using digital platform via creating new channels, finding new customers, and driving deeper engagement with existing ones. API Management provides the core competencies to confirm a successful API program through developer engagement, business insights, analytics, security and protection.
Azure API Management helps you to protect and effectively scale back-end, and launch a full-fledged API program for your business.
Azure API Management enables you to use Azure AD (and Azure AD B2C) as an identity provider for user sign in on the developer portal.
By default, Azure assigns a subdomain of azure-api.net (for example: apimdemo-neosalpha.azure-api.net). However, API Management allows you to expose your API Management endpoints using your own domain name.
Azure VNETs allow you to position any Azure resource in an exceedingly non-internet routable network. These networks can be connected to your on-premises networks utilizing various VPN technologies. Azure API Management is deployed inside the virtual network (VNET), so it can access back-end services within the network. The developer portal and API gateway is configured to be accessible either from the online or only within the virtual network.
Multi-region deployment enables API publishers to distribute Azure API management service across any number of supported Azure regions. It helps you to reduce request latency perceived by geographically distributed API consumers and improves service availability if one region goes offline.
Subscriptions are an important concept in Azure API Management. This allow you to access APIs published through an API Management instance.
Using Response caching you can significantly reduce API latency, bandwidth consumption, and web service load for data that does not change frequently.
Using Azure API Management you can publish multiple version of one API. You can change current version of your APIs to any published version using versioning option in Azure API Management.
API Management provides you to configure notifications for specific events and to configure e-mail templates that are used to communicate with the administrators and developers of an API Management instance.
API Management provides the aptitude to secure access to APIs (i.e., client to API Management) using client certificates. we are going to validate the incoming certificate and check certificate properties against desired values using policy expressions.
Backup and Restore features helps you to implement a disaster recovery strategy. It should be used for replicating API Management service configuration between operational environments, e.g. development and staging.
With the self-hosted gateway, you can deploy a containerised version of the API Management gateway component to the identical environments where you can host your APIs. All self-hosted gateways are managed from the API Management service they're federated with, thus providing the visibility and unified management experience across all internal and external APIs.
You can use various inbound, outbound and on-error policies to modify the APIs requests and responses. Some of frequently used policies are mentioned below:
Access restriction policies –
Advanced policies –
Transformation policies –
Sometimes for security reasons you want to hide original info about the technology stack that is running on the back-end. You can also hide original URLs that appear in the body of API's HTTP response and instead redirect them to the APIM gateway.
CORS is required to let portal visitors use the interactive console in the API reference pages and can be enabled for domains, including custom domains.
Azure API Management offers an end to end solution for managing the lifecycle of your APIs. If you are starting your API journey or want to simplify and streamline your approach to APIs, Azure API Management service is a good choice.
