62. Cloud Caveats
• Honest clouds admit they have
downtime. So will the others.
Instances will fail, though not much
more often than real servers.
• Performance can be impacted by
other local activity.
• Virtual disks tend to have relatively
poor I/O performance.

63. Solutions
• Accept the inevitability of failure.
• Embrace the paradigm of redundancy
and rapid recovery.
• Develop architecture with modular,
replaceable parts.
• Stay fast by minimizing disk/cpu
utilization for menial tasks.

64. The Cloud in Production
• Monitor your load.
• Spin up more instances (scale
horizontally) as you need more power.
• Add layers (scale vertically) as bottlenecks
emerge.
• Create Images for each piece in your
infrastructure.
• Best Practices To Stay Speedy

66. High Performance Drupal Architecture
• Front-side caching: Use Pressflow with
Varnish and/or NgineX.
• Opcode cache (APC) keeps your bits hot.
• Memcached helps to minimize queries to
the database.
• Use dedicated, separately-scalable tools
where possible, like ApacheSolr search.
• Architect for vertical scaling by utilizing
all service layers, even if it’s one box.

68. Technical Info
Mercury is a standardized high
performance stack for Drupal. It
is available in source format, or
(soon) as an on-demand service.
It utilizes the best available
open-source technologies to
make our favorite CMS very fast
and to hold up under large
spikes in traffic.
