Upstream Servers & Load Balancing
Configure Nginx upstream blocks to manage multiple backend servers and distribute incoming requests.
Scaling Your Applications
As your web application grows, a single server might not be enough to handle all incoming requests. This can lead to slow response times or even crashes.
To prevent this, we use multiple backend servers to share the load. This improves both performance and reliability.
Introducing Upstream Servers
Nginx can act as a reverse proxy, distributing requests to a group of backend servers. These backend servers are often called upstream servers.
- Scalability: Handle more traffic by adding more servers.
- High Availability: If one server fails, others can still respond.
- Load Balancing: Distribute requests efficiently among servers.
