ARES: The Application Gateway for WordPress from Pagely

We spent most of 2017 developing a new web application gateway to better serve the tens of billions of requests to Pagely hosted WordPress sites. There’s been a lot of talk on our blog about new features and releases for 2018 so here we’d like to share a few details about how it works, the value it provides to our customers, and why we are so excited about it. ARES is a web application gateway
Great you say, but what is that? Essentially a web application gateway is a middleman between the wider Internet and the specific systems that serve up the application or website. In our case, ARES (Air-eez) takes incoming requests for a WordPress website that we host, filters and routes those requests to the proper machines, and then passes the response (with additional filtering) back to the browser that made the request.
A more technical definition:
Application gateways provide high-level secure network system communication. For example, when a client requests access to server resources such as files, Web pages and databases, the client first connects with the proxy server (gateway), which then establishes a connection with the main server. This connection is hidden to the client
