Preparing your store for peak traffic Environment – Load Balancer
Need new content (Visual/definition/how it helps)
• load balancer is a software/hardware
solution that distributes the load
between your servers.
• Makes scaling possible
• Removes single point of failure
23 October 24, 2012
Preparing your store for peak traffic Environment – APC Accelerator
Need new content (Visual/definition/how it helps)
• APC accelerator - Caches and
optimizes your PHP code for
faster page response times.
• Could also be used as
alternative storage for
Magento cache
24 October 24, 2012
Preparing your store for peak traffic Environment – Cache Storage
Need new content (Visual/definition/how it helps)
• Cache storage - is a place for storing
your Magento application cache.
• Different cache storage options are
available – APC, memcached,
filesystem, sqlite
• For deployments with a large catalog
and multiple stores we recommend
trying REDIS server.
25 October 24, 2012
Preparing your store for peak traffic Environment – External Caching
Need new content (Visual/definition/how it helps)
• CDN - A content delivery network (CDN) is a network of servers
deployed around the world serving images, files, etc.
• A CDN helps to ensure that content is delivered to clients from a
source which is physically closest to them
26 October 24, 2012
Preparing your store for peak traffic Environment – External Caching
Need new content (Visual/definition/how it helps)
• Reverse proxy software allows you to store your cached content separately from the application. The most popular solutions used with Magento are Varnish and ngnix.
• Separate servers and subdomains can be used for images, styles, JavaScript and other content.
27 October 24, 2012
Preparing your store for peak traffic Environment – Database Replication
Need new content (Visual/definition/how it helps)
• Database Replication helps reduce
load on your primary database server
and allows your site to serve more
visitors at one time.
• Replication can also be used for
backing up the database without
affecting site performance as well as for
high availability configurations.
28 October 24, 2012
• Monitoring software constantly scans your servers gives you an overall picture of your system’s performance and health.
• Use monitoring in addition to what your hosting provider offers you. • Graphing helps you find typical load patterns. It is also very useful for
understanding your system’s behavior at different times of the day before the holiday season.
• We have had success using Cacti for graphing and Nagios for monitoring.

Preparing your store for peak traffic Environment – Load Testing
• Load testing is the process of putting demand
on a system or device and measuring its
response.
• Load testing is performed to determine a
system’s behavior under both normal and
anticipated peak load conditions.

During the storm: Operating your store under peak traffic
Top Tips To Keep In Mind
• Avoid massive updates such as importing/exporting products or
database backups during business hours
• Monitor your system and customer activity
• Don’t flush your cache during peak traffic
• When updating your catalog, switch indexes to manual mode
• Make sure you time cron jobs to run after business hours or
during periods of low traffic
• Make sure you can scale quickly
