DESCRIPTION
Kent Mitchell, Director of Product Marketing at Zend, led this session at the RightScale User Conference 2010 in Santa Clara. Session Abstract: The cloud is the new “holy grail” for a lot of people. The cloud enables sites to ramp up new servers for increased load and then ramp down servers when the load decreases. This minimizes upfront costs and provides “pay as you go” cost structure. This scenario is very compelling, especially for startups where budgets are tight. But it also presents some challenges such as making sure the new servers are identical to the existing servers, monitoring the ever-changing cluster, and retaining critical problem data when servers ramp down. In this session, we’ll demonstrate how using Zend Server Cluster Manager together with the RightScale Cloud Management Platform provide solutions for managing cloud-based, highly available PHP server clusters.

PHP Architecture is Perfect for the Cloud
• Linear scalability
Stateless nature of PHP
• Share nothing architecture
• Add Servers for Scaling
Deterministic execution
• No GC or other activities
• Broad DB support
Support for almost all DB technologies
• Pick the one that is best for you
DB side connection pooling
• DB2, Oracle

But … People can break anything
•Treat the cloud instances like “physical machines”
Deploy multiple apps to the server (limits scalability)
Oversize instances (too much capacity)
• Introduce Single Point of Failure
Choose the wrong DB (complex scaling)
Memcache servers for data caching
• Introduce non-linear scalability
Clustering support is typically centralized
