Nginx Server Load balancer dual-host High Availability
If the Web server cluster is used as a city pool, the load balancing server is equivalent to the city gate, and its importance is self-evident. If the "City Gate" is closed, the access to the outside world will be broken. If a server is balanced, when the server fails, the whole website will be inaccessible.
Hi, today we will learn how to use Weave and Docker to build an Nginx reverse proxy/Load balancer server. Weave can create a virtual network that connects Docker containers to each other, enabling cross-host deployment and Autodiscover. It allows us to focus more on the development of the application rather than on the infrastructure. Weave provides such a great environment as if all its containers belong t
Nginx reverse proxy and Server Load balancer

Reverse Proxy(Reverse Proxy) means to use a Proxy server to accept connection requests on the internet, and then forward the requests to the server on the internal network, return the result obtained from the server to the Client Requesting connection from the internet. The proxy server is displayed as a server.

Network Load Balancing Configuration OverviewNetwork load balancing is a network driver for Windows 2000. Its operations are transparent to TCP/IP network stacks.
To ensure optimal network performance, network load balancing usually uses a network adapter to handle customer-to-cluster traffic, while other netwo
