⛩️ API Gateway

⛩️ API Gateway

⛩️ API Gateway is an intermediary between a client and a server which plays a privotal role in implementing MSA services.

API Gateway provides the below features:

• 🚥 Routing/Forwarding
• 👮 Security
• 🔌 Protocol Translation
• ✍️ Logging
• ⚙️ Others

API Gateway is often considered as a superset of a reverse proxy implying that an API Gateway offers all the available features of a reverse proxy and offers more features. Below could be a good comparison between the two:

🚥 Routing/Forwarding

🚥 Routing/Forwarding is a feature that forwards a request into a service that runs the most relevant URL.

Routing/Forwarding in API Gateway can be considered as identical to the same feature in a reverse proxy, and via Routing/Forwarding application's overall performance (low latency) and management can impove following:

• Load Balancing
• Reduced Return Trips
• Filters
• API Management
• Caching

👮 Security

👮 Security in API Gateway refers to extra security layers that consist of authentication, authorisation, rate limiting and etc.

---

🔌 Protocol Translation

🔌 Protocol Translation is a feature that converts a requested protocol into a server-acceptable protocols.

---

✍️ Logging

✍️ Logging refers to the same logging at the app-level in which in the MSA environment, undertaking the app-level logging implicitly impose difficulties in analysing.

API Gateway becomes a good point where a Logging could take place followed by the fact that all requests are incoming via API Gateway if implemented.

⚙️ Others

In regards of others features of API Gateway, common features can be aggreated and orchestrated to present data in a short latency as well.
