to be implemented.

• Intranet redesign;

• To adopt the Corporative Portal concept;

Now, let me present how the Intranet pages looks.

It looks like this:

Varnish

Varnish is an HTTP accelerator designed for content-heavy dynamic web sites. In contrast to other HTTP accelerators, many of which began life as client-side proxies or origin servers,

Used on our intranet for static content cache. Delivers 80% from our users access.

NginxIt's a lightweight, high-performance Web server/reverse proxy and e-mail (IMAP/POP3)

Used on our intranet for:• Layout images• CSS• Javascript• Flash files• FLV streaming • gzip compression

Pound

Pound is a lightweight open source reverse proxy program suitable to be used as a web server load balancing solution.Developed by an IT security company, it has a strong emphasis on security.

Used on our intranet for stick session balancer.

MemcachedIt's a general-purpose distributed memory caching system. It is often used to speed up dynamic database-driven websites by caching data and objects in RAM to reduce the number of times an external data source

Used on our intranet for caching the most used methods or that ones that have a slowly processing

• Local cache using web browser;• Autenticated Users;

Solution• Use a Dedicated Server

LLocal cacheocal cache

Solution• Varnish implementation.

The images are stored on a server using a domaincreated specially for this task

Details are everything

The "how" details are ...

• To use Zope Component Architecture(ZCA) for developing applications

• To use memcached

• By using the egg format

• To use AJAX

• To optimize the code for making the page size smaller

And more, "how" details are ...

• To compress javascript and CSS codes

• To use gzip to compress the page

• To study content and application by creating a large cache identification policy

• Cache policy is alive

• To use Varnish as Cache accelerator

First Stress Test

• Using Squid Cache Server

• A simple apache benchmark test (with anonimous user), with, 100 thousand accesses and 3 thousand concurrency

• Which results are, 500 requests per second, that's good

Second Stress Test

• Using Varnish Cache Server

• A simple apache benchmark test (with anonimous user), with, 100 thousand accesses and 3 thousand concurrency

• Which results are, 9800 requests per second, that's pretty good.

• This is the “why” reason to use Varnish

What does the setup look like?

• Nginx (layout images, video streaming and access logging)

• Varnish (Caching content)

• Pound (Load balancer)

• Zeo Clients & memcached

• Zeo Server

Any Questions?
