- 4. MORE INFORMATION AT NGINX.COM What’s New in Drupal 8 1. Mobile improvements. Full support for mobile site templates and easy backend administration from a mobile device. 2. Data and presentation layer uncoupling. The Drupal API is now fully RESTful, making it easier to use with Angular.js, Ember.js, and other client-side content extraction and display tools. 3. Support for Symfony2. Symfony 2 is an up-to-date, object-oriented PHP framework, well known for customer relationship management (CRM) integration. 4. Twig support. Twig is a frontend library and template engine that eliminates some disadvantages of pure PHP while embracing the latest PHP standards. 5. Security improvements. New features offer additional ways to make systems more secure.

- 6. MORE INFORMATION AT NGINX.COM Planning Your Site Architecture 1. Current architecture. Evaluate your current site traffic and performance. 2. Goals. Immediate problems, future growth 3. Estimate impact of changes. Open source NGINX or NGINX Plus as web server, reverse proxy server, load balancer, more. 4. Plan for growth. Estimate likely and possible growth and speed of growth. 5. Factor in the cloud. Use cloud from scratch, expand into the cloud, move into the cloud.

- 8. MORE INFORMATION AT NGINX.COM Replacing Your Web Server 1. Replace Apache with NGINX or NGINX Plus. Immediate performance fix. Enables caching for static and dynamic content. (More on this soon.) Does not enable multiple app servers. 2. More performance on same hardware. Event loop replaces thread-per-connection, solves C10K problem. 3. Requires new server configuration. Replace familiar Apache configuration with tighter, more efficient (IMHO) NGINX configuration. 4. Independent of NGINX as reverse proxy server. You can use NGINX as a reverse proxy server with or without using NGINX as your web server; very flexible.

Other is queued. • proxy_cache_use_stale – Serve stale content when while cached entry is being updated
