ApacheCon: Core Europe 2015

The Apache HTTP Server module configuration API is challenge even for seasoned httpd developers. Per-server and per-directory configuration scopes, merging of configuration sections, optimizations to survive complex configurations, and configuration directive handling are all challenges to the beginning and even an adept Apache module author. Join us as we unwind this complexity for the new module author or existing module hacker and offer best practices, promote more robust module configuration, and allow for easier introduction of new features with less code.

While almost everyone has finally moved off of httpd 1.3, lots of people are still using 2.0 or 2.2, and many of those that are on 2.4 are using it as though they're still on 1.3.

It's like your driving your Ferrari in first gear. With the brakes on.

Apache HTTPd 2.4 is lightyears ahead of what went before, and if you're not using the new functionality, you might as well be using nginx. Come earn about conditional configuration, the event MPM, magical proxy configuration, the general purpose expression parser, and so much more.

Tomcat provides a cluster feature.
However, Some of the cluster components will depend on each other. And it confuses developers.
In this session, you'll be able to learn a Tomcat cluster correctly in detail.
And, it will enable you to configure the optimal Tomcat Cluster.
The main topics of this session are:
-Architecture
-Session replication
-Cluster channel component

In this talk he is going to introduce new open source framework Frontera https://github.com/scrapinghub/frontera. Frontera allows to build real-time, large scale, distributed web crawlers and website focused ones. Offering:

• customizable storage (RDBMS or Key-Value based),
• crawling strategies management,
• transport layer abstraction,
• fetcher abstraction.

Along with framework description he'll demonstrate how to build a distributed crawler using Scrapy, Apache Kafka and HBase, and hopefully present some statistics of Spanish internet collected with newly built crawler.
