What is TCP proxy load balancing?

TCP Proxy Load Balancing is a reverse proxy load balancer that distributes TCP traffic coming from the internet to virtual machine (VM) instances in your Google Cloud VPC network. The TCP proxy load balancer automatically routes traffic to the backends that are closest to the user.

Is NGINX a load balancer or reverse proxy?

Ideal for cloud-native environments, NGINX Plus is a software-based reverse proxy that performs load balancing, Layer 7 routing and web performance optimization, similar to a hardware device. NGINX Plus can be deployed in the public cloud as well as in private data centers at a lower cost than a full proxy.

Can NGINX do load balancing?

It is possible to use nginx as a very efficient HTTP load balancer to distribute traffic to several application servers and to improve performance, scalability and reliability of web applications with nginx.

Does NGINX support UDP?

UDP load balancing with NGINX and NGINX Plus is suitable for any UDP‑based application that sends data and optionally expects one or more responses. NGINX can also load balance proprietary UDP‑based protocols such as those found in IoT environments.

What protocols can NGINX proxy?

With the PROXY protocol, NGINX can learn the originating IP address from HTTP, SSL, HTTP/2, SPDY, WebSocket, and TCP.

Is NGINX a layer 4?

Modern general-purpose load balancers, such as NGINX Plus and the open source NGINX software, generally operate at Layer 7 and serve as full reverse proxies.

Why NGINX is called reverse proxy?

nginx is a web server, similar to apache and IIS . Like many web servers it can be configured to work in forward proxy mode or reverse proxy mode. The phrase “nginx reverse proxy” means the nginx server configured as a reverse proxy.

Is NGINX a reverse proxy?

NGINX Plus and NGINX are the best-in-class reverse proxy and load balancing solutions used by high-traffic websites such as Dropbox, Netflix, and Zynga. More than 400 million websites worldwide rely on NGINX Plus and NGINX Open Source to deliver their content quickly, reliably, and securely.

Is NGINX better than Apache?

NGINX performs 2.5 times faster than Apache according to a benchmark test performed by running up to 1,000 simultaneous connections. Another benchmark running with 512 simultaneous connections, showed that NGINX is about twice as fast and consumed less memory.

What is TCP and UDP load balancing?

Google Cloud Internal TCP/UDP Load Balancing is a regional load balancer that is built on the Andromeda network virtualization stack. It enables you to run and scale your services behind an internal IP address that is accessible only to systems in the same VPC network or systems connected to your VPC network.

Can you load balance syslog?

Traditionally, if you want to load balance Syslog in your environment, you would use an F5 BIG-IP or a Citrix Netscaler. Because NGINX now supports Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) load balancing, an open-source solution can be built to manage this.

Is NGINX layer 7 load balancer?

The comprehensive Layer 7 load balancing capabilities in NGINX Plus enable you to build a highly optimized application delivery network. When you place NGINX Plus in front of your web and application servers as a Layer 7 load balancer, you increase the efficiency, reliability, and performance of your web applications.

What do you mean by load balancing in Nginx?

Load balancing refers to efficiently distributing network traffic across multiple backend servers. In NGINX Plus Release 5 and later, NGINX Plus can proxy and load balance Transmission Control Protocol) (TCP) traffic. TCP is the protocol for many popular applications and services, such as LDAP, MySQL, and RTMP.

How does the PROXY protocol work in Nginx?

Introduction The PROXY protocol enables NGINX and NGINX Plus to receive client connection information passed through proxy servers and load balancers such as HAproxy and Amazon Elastic Load Balancer (ELB). With the PROXY protocol, NGINX can learn the originating IP address from HTTP, SSL, HTTP/2, SPDY, WebSocket, and TCP.

What’s the difference between UDP and TCP in Nginx?

TCP is the protocol for many popular applications and services, such as LDAP, MySQL, and RTMP. In NGINX Plus Release 9 and later, NGINX Plus can proxy and load balance UDP traffic. UDP (User Datagram Protocol) is the protocol for many popular non-transactional applications, such as DNS, syslog, and RADIUS.

Can You proxy and load balance UDP traffic?

Similarly, Nginx Plus can proxy and load balance UDP traffic. User Datagram Protocol (UDP) is the protocol for many popular non-transactional applications, such as DNS, Syslog, and RADIUS.
