1. HOW TO MAKE YOUR SITE ON DRUPAL 8 FLY WITH REDIS
2. Pantheon.io Why Caching? Caching means less traffic hitting your site’s servers. At the most basic level, cached content and processes are stored and served from your cache servers. This provides a much faster load time for visitors. And in turn means there are more resources available for the processes that cannot be cached - helping those to run faster as well!
3. Pantheon.io Full page cache is probably the single best thing you can do to increase your site performance. Implementing full page cache A reverse proxy can deliver up to 200x improvement in speed and volume. Full page cache effect - cache hits load in about 0.2s, compared to 1.7s for a page load from the server. 3
4. Pantheon.io Authenticated traffic Full page cache is great for anonymous users and serving static pages. 
 However, not everything can be handled with full page cache - for this we have Redis. 4
5. Varnish Caching
6. Pantheon.io Varnish Caching on Pantheon Varnish caching − is in place automatically − preconfigured/optimized to maximize site performance − can be modified, but no custom VCL (Varnish Configuration Language)
7. Pantheon.io Traffic Flow with Varnish in Place
8. Pantheon.io 8 Massive, multi-tenant platform Dedicated infrastructure 1,000,000+ Containers 6,000,000,000+ Pageviews/Month Big needs? We can handle them. See How it Works for more information Our Architecture
9. Pantheon.io 9 The Edge Exterior - touching the Internet 
 Ultra-fast Varnish cache
 Intelligent Routing + Load Balancing 
 Hands off to Runtime Matrix See How it Works for more information
10. Pantheon.io Varnish full page cache " Caches entire output " Abides by headers " Can be busted with cookies
11. Pantheon.io Checking Varnish Age Use curl -I to check age of page using headers Age: 0 means the page isn't being cached by Varnish
12. Pantheon.io Cache Clearing Clear the cache from your Site Dashboard - or Terminus to clear the application and Varnish caches $ terminus env:clear-cache <site>.<env> or $ terminus drush <site>.<env> -- cc all or $ terminus wp <site>.<env> -- cache flush Hint: If you still aren’t seeing your changes - it may be cache locally or on your network. Try an incognito browser, or checking the site from your phone with the wifi turned off (so that it is using the cellular network instead).
13. Pantheon.io Cache Clearing Pantheon Edge is getting an upgrade. Plugin/module for clearing cache automatically, plays nice with REST More information on this when we review the Global CDN!
14. Global CDN
15. Pantheon.io What is Global CDN " Preconfigured on every Pantheon site " Over 30 edge locations around the globe " HTTP/2 " Includes free Managed HTTPS on all domains ◦ HTTPS with an A+ rating on SSL Labs ◦ Auto renewal of certificates with Let's Encrypt ◦ No need to pay an additional monthly fee

29. Pantheon.io Redis
30. Pantheon.io Dedicated object cache
31. Pantheon.io Dedicated object cache Requests to the object cache bypass MySQL The object cache is served from memory and is more performant
32. Pantheon.io Dedicated object cache " WordPress and Drupal both integrate with persistent/external storage backends like Redis or Memcached " Easily done with plugins/modules " This speeds up PHP execution time while lessening the load on the Database ◦ For example, WordPress transients are stored in memory instead of the database
33. Pantheon.io Object caching on Pantheon Use the Drupal Redis Module or the WordPress Redis Plugin
34. Pantheon.io Dedicated object cache Be careful not to cache too much information in Redis, it does have a limit. Once you have exceeded the limit, requests will pass through, uncached, to MySQL
