In 2011, Google announced PageSpeed, a new optimization service, bringing CDN-like benefits to small web sites owners developers (see "Google Optimizes Web sites and Brings CDN Service to the Masses" - here),
Apparently, this was not a huge success, and Google annouced recently that "After 4.5 years of service, the PageSpeed Service team regretfully decided that the time had come to re-focus their efforts elsewhere and on 5th May announced that PageSpeed Service will be turned down. If you are using PageSpeed Service, you must change your DNS before 3rd August 2015 or your site(s) will become completely unavailable on that date."
Google suggests on of the following alternatives:
- Provider Hosted PageSpeed - Many web hosting providers already integrate PageSpeed. If you are using such a web hosting provider, check your provider’s documentation. It may be as simple as checking a box in your provider’s control panel.
- Server side modules - There are PageSpeed modules for many common web servers. If you run your own web server, you may wish to install one of these.
- Apache - Google has developed the open-source Apache module mod_pagespeed. Pre-built binary modules for Apache 2.2 and 2.4 are available. For more information, click here.
- Nginx - Google has also developed a plugin for Nginx. Due to the nature of Nginx, it must be compiled from source. You can read the instructions here.
- IIS - The folks over at WeAmp have a commercial port of PageSpeed to Microsoft IIS. You can learn more about it at www.iispeed.com.
- Apache Traffic Server - WeAmp has ported PageSpeed to Apache Traffic server. More information, including build instructions, can be found at www.atsspeed.com.
- OpenLiteSpeed - OpenLiteSpeed supports a PageSpeed module that you can compile and load into your webserver. Please see their instructions here.
- Cloud based alternatives - If you wish to continue using cloud-based product, EdgeCast Edge Optimizer [see "CDN Announcements: EdgeCast Shows 77% Performance Improvement w/Integrated Google’s PageSpeed" - here] integrates Google PageSpeed with their CDN offering. Alternatively, many CDNs offer comparable functionality that does not use PageSpeed technology.
