Zend Platform is a software that sits between PHP and the server, providing visibility into code running in production through features like event logging and profiling. It offers capabilities like session clustering across servers, caching to improve performance, and asynchronous job queues. The document discusses using more of Zend Platform's features to optimize applications, such as Java integration for faster page generation and reducing errors in production.
Zend Platform
- 2. Zend Platform We have it It's not cheap We're using it, but to nowhere near its full potential
- 3. What is Zend Platform? It's a piece of software which sits between PHP and the server; a managed environment in which our PHP code runs It gives us visibility on what our code is doing in production (event log, profiling) And a lot of other cool tools
- 4. What are we Using? Event Log Accelerator The tip of the iceberg
- 5. Even Actions: proactive monitoring Post XML to a URL Send email – without cluttering up the application code Send SNMP trap, which can be caught by Nagios
- 6. Session Clustering PHP Sessions can be troublesome in a multi-server environment Need for NFS server/database/Session Server Works like JBoss session clustering Sessions can live in memory Simply a case of “switching it on”
- 7. Caching Platform can act as a “back-end” for caching Zend Framework provides a simple API
- 9. Caching - benefits Cache shared between servers Cache could be shared between and applications e.g. Content API calls No fuss with cache files/directories/permissions/sysadmins No need to clean up expired cached objects
- 10. Job Queue Ability to “offline” processing and have it done asynchronously Asynchronous processes run within Platform, the same as “normal” code
- 11. Java Bridge Our page-generation times are relatively slow Most of that is SOAP calls to Java services Java Bridge allows us to import Java objects and treat them as if they were native PHP objects So we could write an e.g. SessionServer client in Java, which talks to SessionServer over RMI. Performance increase could be impressive (requires benchmarking)
- 12. Going Forward This is only a few of the features, let’s get thinking about how we can use some of this stuff Work out which issues are critical enough to escalate to Nagios Try to reduce the number of errors/notices we are creating in production
