RightScale Conference NYC 2012 -- PHP Apps on the Move - Migrating from In-House to Cloud Kent Mitchell - Sr. Director, Product Management, Zend It’s a common problem: How to move your PHP system to the cloud without completely overhauling your app. Most existing systems and applications were not designed for the level of elasticity the cloud brings. But many of those apps can still take advantage of all that the cloud offers - while requiring very few modifications. In this session, we will discuss how one customer leveraged the off-the-shelf capabilities of RightScale and Zend to migrate from a fixed, non-scalable traditional architecture to an elastic, high-availability cloud architecture. Join us for a deeper look at this auto-scaling PaaS solution specifically designed to make it easier for you to deploy and manage cloud-based, highly available PHP server clusters.

9. Problems
• No room for traffic bursts
• FRAGILE - Don't want to upgrade X because it
may break Y.
• Single point of failure - could shut down our
business for hours to days.
• Encouraged manual "hacking". Rather than run
the proper build script, I'll just tweak this file on
the live site. It's OK...
