Nginx Reverse Proxy Upstream Ssl

What is Nginx Reverse Proxy?

Nginx reverse proxy is a technique used to provide internet users with the ability to access services on a variety of different web and application servers, while remaining unidentifiable to the end user. It allows a web server to be invisible, while still servicing requests from multiple systems or applications. By using an Nginx reverse proxy, a web administrator can manage all requests within a single interface. This can be used to improve security, scalability, reliability, and performance by redirecting traffic to particular services according to the request.

How Does Nginx Reverse Proxy Work?

Nginx reverse proxy operates by exposing a designated web port to the internet that is not directly linked to any of the services behind the proxy. It acts as a middleman, gathering data from the incoming requests, and forwarding the information to the properly designated services. In the event of requests to the proxy from restricted services, the request is denied.

The proxy can also be configured to accept requests from authorized IP addresses. The reverse proxy server can then decide what services to direct traffic to. For example, if a request is made for a website hosted on one of the web servers, the reverse proxy will direct the traffic to that server. The proxy may also decide to forward traffic to multiple services, such as a caching service, or a distributed content delivery network, to improve the response time of a website.

What is the Need for SSL?

Secure Sockets Layer (SSL) is a technology which can be used to provide an added layer of security to any service handled by an Nginx reverse proxy. SSL allows for the encryption of data in transit. That encryption can be used to protect the user from malicious activities such as man in the middle attacks, or other forms of data tampering. By using a dedicated certificate for each application or service, a user can be sure that the data they are sending is secure. Additionally, websites can also be secured with SSL to provide a higher level of trust to their users.

What is Nginx Upstream SSL?

Nginx upstream SSL is a feature of the Nginx reverse proxy that enables the use of SSL encryption within a given server group. Upstream SSL works by securely connecting upstream servers to the reverse proxy server. It keeps the data secure throughout the entire communication process, which ensures that the data transfers between multiple services remains secure. This is especially useful for services that need to store sensitive data, such as Credit Card numbers, or other personally identifiable data.

What is the Difference Between Nginx Reverse Proxy and Nginx Upstream SSL?

Nginx reverse proxy is used to redirect requests from the internet to the services that can provide those requests, whereas Nginx upstream SSL is used to connect those services in a secure manner. Reverse proxy is a layer between the internet and the server, where upstream SSL is a layer between the reverse proxy and the servers. Furthermore, reverse proxy provides access control by allowing or denying requests based on certain criteria, such as IP addresses or web browsers, while upstream SSL encrypts the data that is transferred between the services.
