Reverse Proxy Saas
Is there a cloud-based reverse proxy solution in AWS?
I have an API deployed on EC2 machines on AWS. Incoming HTTPS requests are passed to an elastic load balancer. The load balancer handles the SSL, and passes the request to an Nginx server, that proxies the requests to the specific servers according to the request URL.
Nginx machines require a lot of maintenance work, especially when servers IP addresses are changed. Moreover, URL-based proxy routing really seems like a natural continuation of a load balancer. Having a sane web-based or API-based interface to control URL routing would be a tremendous boon.
Is there any cloud-based routing solution that can proxy HTTP requests by URL schemas, replacing my Nginx machine?

You can use AWS API Gateway (documentation).
API Gateway helps developers deliver robust, secure and scalable mobile and web application backends. API Gateway allows developers to securely connect mobile and web applications to business logic hosted on AWS Lambda, APIs hosted on Amazon EC2, or other publicly addressable web services hosted inside or outside of AWS. With API Gateway, developers can create and operate APIs for their backend services without developing and maintaining infrastructure to handle authorization and access control, traffic management, monitoring and analytics, version management and software development kit (SDK) generation.
API Gateway now supports HTTP Proxy integration for pass-through resources, so you don’t need to describe your payload and query params explicitly (which was required previously).

Take a look at Kong.
Besides being open-source, you can operate it using its internal RESTful API, and you can extend it with custom plugins.

Just to add to @EdwardSamuel’s answer:
Yes, the there is, and the proper AWS service for this is Application Load Balancer.
However, I’m really curious if @EdwardSamuel’s answer really works because I’m also interested in using API Gateway for this purpose. I’m aware of some limitations with API Gateway (content-length limit, etc. ) but I’m not sure yet whether these limitations will make it unusable to, say, reverse proxy a WordPress blog.

Configuring SaaS proxy certificates – Riverbed Support
Configuring SaaS proxy certificatesConfiguring SaaS proxy certificatesProxy certificates are certificates specific to a particular SaaS domain that are signed by a CA trusted by the client applications inside your network. SaaS proxy certificates allow the Cloud-hosted SteelHead to intercept and accelerate secure sessions between the SSL-based client and server SteelHead SaaS does not support self-signed SaaS proxy certificates; it only supports CA-signed SaaS proxy certificates can come from either of these sources: a third-party, cloud-hosted CA or a CA within your change the type of Certificate Authority1. Log in to the Riverbed Cloud Portal. 2. Select Cloud Accelerator to display the Cloud Accelerator page. 3. Select SaaS Platforms to display the SaaS Platforms page. 4. Under Proxy Certificate Authority, the CA used to sign the SaaS server proxy certificates appears. Click change mode to select one of these options:• Cloud-Hosted CA- In this mode a third-party, cloud-hosted CA signs the proxy certificates. • Customer CA – In this mode your company’s CA signs the proxy the SaaS Platforms page, under Manage SaaS Platforms, select the name of a SaaS platform listed in the table to display the SaaS Service Details page. The section under SaaS Platform Proxy Certificates changes depending on the CA mode that you select on this SaaS Platforms use proxy certificates issued by a third-party, cloud-hosted CA1. Under Proxy Certificate Authority, click change mode and select the Cloud-Hosted CA mode. Click View/Download CA Certificate to download the CA certificate from the Riverbed Cloud Portal. 5. Install the certificate on all clients that access the SaaS application by either:• adding it directly to the client’s • adding it to the certificate store of the client’s Windows operating system. 6. Optionally, click Request New Proxy Certificate Authority to regenerate the proxy CA and confirm your Regenerating the proxy CA might disrupt existing SSL connections. 7.

Use the CSR to obtain your CA’s signature on your proxy certificate. Select Upload Certificate in the table (next to the specific SaaS hostname). 11. Select the signed proxy certificate from your local file system or copy and paste the certificate details and click Upload to upload the proxy certificate for the specific SaaS hostname.
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.
How Can NGINX Plus Help?
NGINX Plus and NGINX are the best-in-class 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.
As a software‑based reverse proxy, not only is NGINX Plus less expensive than hardware‑based solutions with similar capabilities, it can be deployed in the public cloud as well as in private data centers, whereas cloud infrastructure vendors generally do not allow customer or proprietary hardware reverse proxies in their data centers.

What is reverse proxy vs proxy?
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.Mar 31, 2021
