The S in SAMP stands for SolarisSolaris Zones

★ Free, lightweight and easy virtualization★ Allocate a “system” to each app instance or to each developer★ Resources are controlled in one of three ways

• Capped Resources: Upper limit on consumption• Guaranteed Resources: Guarantee of a minimum available• Dedicated Resources: Resources are set aside for

★ share filesystems and network across zonesOR

★ dedicate filesystems and network to individual zones


15

Need Efficiency & Control?Hypothetical Constraints & Objectives

Constraints: one server available need to host four environments:

(2) Developers (1) Test environment (1) Production environment

Objectives: maximize sharing, minimize redundancy guarantee max. resources for production maximize efficiency & consistency btw. envs.

“DTrace is one of those tools that makes you wonder how you did anything without it before you'd heard of it. Why is it better than strace and similar tools? It's non-invasive, fast, scriptable and extensible.”

- Wez Furlong

Find Hampster Wheels with DTraceDTrace provider for PHP


Performance Tuning - DEMODTrace provider for PHP

Which functions are being called by Drupal?# dtrace -n function-entry'{printf("called %s() in %s at \ line %d\n",copyinstr(arg0), copyinstr(arg1), arg2)}' -q

How many times is a function called?# dtrace -n function-entry'{@[copyinstr(arg0)] = count()}'

What's the file name and line number count:# dtrace -n function-entry'{@[copyinstr(arg1)] = \ lquantize(arg2, 0, 5000)}'

Security

RBAC− Assign users to roles with privileges they need

Process Rights Management− Run with least privileges− E.g., not root, nosuid, noexec


Versioning & Protecting Data
