Since Yesterday IBM provides the Zend PHP pattern on SmartCloud Application Service. This pattern is composed of a Zend PHP server, a possibility to link to DB2 component and also a load balancer.
Two flavors are available for the Zend PHP pattern, the Professional and the Enterprise version. The Professional version is a more lightweight version, for example, the Professional doesn’t support Java Connectors, has a limited data retention for debugging and doesn’t provide audit trail.
Both flavors are available in a PAYGO or BYOL license mode and in 3 sizes (Small/Medium and Large) for an hourly or monthly rate.
You can also order the PHP scaling capabilities to automatically scale up and down your cluster. The cluster will also provide a cache to avoid that data-loss during an HA event or a down-scale.
Zend provides also a framework, called ZF. It allows you to leverage on a number of library to speed-up your development.
You can use the ZendStudio IDE which is Eclipse base to develop your application. You can download a 30 days free trial of the ZendStudio here.
