IPsec (Internet Protocol Security) Gateway: IPsec is a suite of protocols used to secure Internet Protocol (IP) communications. An IPsec gateway is a device or system that acts as an intermediary to provide security services, such as encryption and authentication, for IP traffic between networks. It establishes secure VPN (Virtual Private Network) tunnels between different locations or networks.
API Gateway: In the context of modern software architectures and microservices, an API (Application Programming Interface) gateway acts as a reverse proxy that sits in front of multiple backend services. It can handle tasks like request routing, rate limiting, authentication, caching, and more. Examples include AWS API Gateway, NGINX, and Kong.
SMS Gateway: This is another type of gateway that facilitates the sending and receiving of SMS (Short Message Service) messages. Businesses often use SMS gateways to send bulk messages, notifications, or alerts. These gateways can interface with mobile networks to ensure that SMS messages reach their intended recipients.
