apps by serving the HTML, JavaScript, images and other fixed content from nginx.īelow we see it used to offload TLS and segment public from private subnets: Improve performance of your Tomcat, Ruby on Rails, Django, etc. ![]() You could obfuscate use of a third party application, remove sensitive content, fix a bug, inject CORS headers, automate log in in some SSO flow, and so on. There are multiple directives to search and replace content, usually with the power of regex, specifically Perl Compatible Regular Expressions (PCRE). You have unlimited power to 'rewrite' (transform) request URIs, headers and bodies, and response headers and bodies. A proxy funnels requests through one or a few subdomains and removing any caps on the number of applications (think microservices). The proxy can be put on a public subnet (DMZ) while applications can be on private subnets and only accepting traffic from the proxy.Īpply authentication and authorization to unprotected applications, or apply extra security layers on a protected app, such as source IP whitelists.Īn org could create one subdomain per app, but the SSL certificate costs could be prohibitive. Management of certificates, protocols and ciphers whitelists, and library patching is also simplified. Client performance can can also be boosted when there are multiple endpoints, by aggregating the multiple app interaction into a single TLS session with the proxy. This C-based web server will do TLS more efficiently than Java, Node (JavaScript), Ruby, etc. (TLS is the successor to Secure Sockets Layer (SSL)). I find nginx a perfect fit in these six cases:Īggregate system performance can increase with a proxy handling Transport Layer Security (TLS) for applications. It was designed from the ground up as a non-blocking reverse proxy. I like it because of its performance and the clean configuration approach. Nginx is in the top three web servers, along with Apache and IIS. ![]() This article reviews four ways to route requests from a proxy web server to an origin web server. Reverse proxying web applications and services improves system security, performance and operations.
