What is a Reverse Proxy Server? | NGINX
A proxy server is a go‑between or intermediary server that forwards requests for content from multiple clients to different servers across the Internet. A reverse proxy server is a type of proxy server that typically sits behind the firewall in a private network and directs client requests to the appropriate backend server. A reverse proxy provides an additional level of abstraction and control to ensure the smooth flow of network traffic between clients and servers.
Common uses for a reverse proxy server include:
Load balancing – A reverse proxy server can act as a “traffic cop, ” sitting in front of your backend servers and distributing client requests across a group of servers in a manner that maximizes speed and capacity utilization while ensuring no one server is overloaded, which can degrade performance. If a server goes down, the load balancer redirects traffic to the remaining online servers.
Web acceleration – Reverse proxies can compress inbound and outbound data, as well as cache commonly requested content, both of which speed up the flow of traffic between clients and servers. They can also perform additional tasks such as SSL encryption to take load off of your web servers, thereby boosting their performance.
Security and anonymity – By intercepting requests headed for your backend servers, a reverse proxy server protects their identities and acts as an additional defense against security attacks. It also ensures that multiple servers can be accessed from a single record locator or URL regardless of the structure of your local area network.

The Difference Between Proxy and Reverse Proxy | strongDM
Many businesses use proxy servers to route and secure traffic between networks. There’s often confusion, however, on how this differs from a reverse proxy. In this post, we’ll dissect the two concepts and explain how administrators can use a reverse proxy for easy access management is a proxy server? A proxy server, sometimes referred to as a forward proxy, is a server that routes traffic between client(s) and another system, usually external to the network. By doing so, it can regulate traffic according to preset policies, convert and mask client IP addresses, enforce security protocols, and block unknown stems with shared networks, such as business organizations or data centers, often use proxy servers. Proxy servers expose a single interface with which clients interact without having to enforce all of the policies and route management logic within the clients is a reverse proxy? A reverse proxy is a type of proxy server. Unlike a traditional proxy server, which is used to protect clients, a reverse proxy is used to protect servers. A reverse proxy is a server that accepts a request from a client, forwards the request to another one of many other servers, and returns the results from the server that actually processed the request to the client as if the proxy server had processed the request itself. The client only communicates directly with the reverse proxy server and it does not know that some other server actually processed its request. A traditional forward proxy server allows multiple clients to route traffic to an external network. For instance, a business may have a proxy that routes and filters employee traffic to the public Internet. A reverse proxy, on the other hand, routes traffic on behalf of multiple servers. A reverse proxy effectively serves as a gateway between clients, users, and application servers. It handles all the access policy management and traffic routing, and it protects the identity of the server that actually processes the verse proxy configurationBy routing client traffic through a reverse proxy, admins can simplify security administration. They can configure backend servers to only accept traffic directly from the proxy and then configure the granular access control configurations on the proxy example, admins can configure the reverse proxy’s firewall to whitelist or blacklist specific IP addresses. All existing servers behind the proxy will be protected accordingly, and whenever admins add a new backend server to the network that is configured to only accept requests from the proxy server, the new backend server is protected according to the proxy configuration. Using a reverse proxy can also allow administrators to easily swap backend servers in and out without disrupting traffic. Because clients interact directly with the proxy, they only need to know its host name and don’t need to worry about changes to the backend network topology. In addition to simplifying client configuration, an admin can configure a reverse proxy to load-balance traffic so that requests can be more evenly distributed to the backend servers and improve overall case: onboarding and off-boardingWhen onboarding a new user to a network, administrators must configure access control and firewalls to ensure the user can access the appropriate resources. Traditionally, an admin has to configure each server for which users need access. In a large organization with many servers, this can be a time-consuming and error-prone process. However, with a reverse proxy, administrators can configure the access rights directly on the proxy server and have the user route all traffic through it. As such, the backend servers only need to trust and communicate with the proxy directly. This greatly simplifies the configuration process and helps ensure access is granted and revoked correctly by doing so through a single tting up a reverse proxy for access managementWhile a reverse proxy can greatly simplify the process of managing access to a network, setting it up and configuring it properly can get complicated. It requires provisioning the host with appropriate specifications, configuring the operating system and firewall, deciding on which proxy software to use (such as NGINX or HAProxy), enumerating and configuring the downstream servers in the proxy configuration files, setting up audit logging, and configuring the firewalls in all the downstream servers. An administrator will need to optimize the proxy software to adjust for performance and availability requirements. For example, when a downstream server fails, the admin should configure the proxy server to quickly reroute traffic to avoid scale, the out-of-the-box configurations are rarely sufficient, so testing becomes important. Whenever the configurations change, you’ll need a way to run sufficient load against a representative test environment and closely monitor the impact on both performance and availability to verify that configurations will meet the needs of the production ing a reverse proxy by hand vs. buying softwareGiven all the steps involved in implementing, testing, and optimizing a reverse proxy, you may choose to buy software that can provide this functionality without all the custom work. Access management software can provide all of this functionality while also managing the ongoing maintenance and user management. In addition to providing standard reverse proxy capabilities, access management software affords a number of unique benefits:1) Flexibility with user access. By abstracting away the complexity of firewalls and access control, access management software can provide higher-level concepts like user groups. This functionality makes it easy for admins to assign and remove users from various predefined groups and allows the software to automatically implement the access policies. 2) Designed to boost reliability. In distributed systems, servers can fail and network interruptions may occur. Access management software easily detects failed servers and reroutes traffic to working ones to avoid any noticeable downtime for users. 3) Load balancing capabilities. Single servers may struggle when hit with a large amount of traffic, which degrades performance and increases request latency. Access management software can help to manage traffic and balance the load across all servers, making sure it’s evenly naging access with strongDMThe strongDM control plane is a proxy-based solution that simplifies authentication and authorization for admins.
