An API Gateway is a specialized reverse proxy application and infrastructure, which takes calls from API Consumer applications and routes them to the backend APIs. While routing request and response messages, an API Gateway ensures enforced and implemented API Security, managed API Monitoring and API Alerting, required API Messages Transformations and Orchestrations, and gives API Providers and API Consumers access to in-depth technical and business API Analytics.
A single Sentinet API Gateway (a.k.a Sentinet Node) can manage API Security and API Monitoring of unlimited backend APIs and microservices, and multiple Sentinet Nodes can be deployed to address different requirements for networking and API Security, APIs deployment models and operational environments.
Sentinet Nodes are high-performance, low-latency and scalable API Gateways that provide dynamic facade APIs (or virtual APIs) for the backend business APIs.
Sentinet Nodes can be deployed entirely on-premises in the internal networks, as API Gateways in DMZ, or as cloud applications.
A single Sentinet Node can manage unlimited business APIs and microservices by providing independent virtual APIs.
A Sentinet Node is an installable application, which can be deployed in just a few minutes using either interactive Wizards or fully automated scripts.
