Transforming IT Operations

Transforming IT Operations
IT operations environments are very “noisy”. With tens of thousands of events coming in from thousands of different devices, it’s hard to know when things are “normal” and when things are “not normal”. This is particularly challenging because event traffic and volume from devices can vary depending on the time of the day, the day of week, the week of month, and even the time of year. Given the... Architecting your environment to ensure high availability means designing an architecture where single points of failure are identified and mitigated. In most IT infrastructures, IT services are designed with multiple redundant components, and multiple failures must occur before you finally arrive at a single point of failure ─ the point where, if the final remaining component in the redundant...


How Linux is taking over the network Is world domination by Linux a fanciful dream, or could it be a reality in ways we don't expect? Scott Reeves sees the signs. Is the idea of world domination by Linux as far-fetched as it sounds? Perhaps it is still not deployed on many laptops or desktops worldwide. Does that mean that world domination is a pipe dream?

Puppet Open Source: IT Automation Software for System Administrators Puppet Open Source is a flexible, customizable framework available under the Apache 2.0 license designed to help system administrators automate the many repetitive tasks they regularly perform. As a declarative, model-based approach to IT automation, it lets you define the desired state - or the “what” - of your infrastructure using the Puppet configuration language. Once these configurations are deployed, Puppet automatically installs the necessary packages and starts the related services, and then regularly enforces the desired state. In automating the mundane, Puppet frees you to work on more challenging projects with higher business impact. Puppet Open Source is the underlying technology for Puppet Enterprise and runs on all major Linux distributions, major Unix platforms like Solaris, HP-UX, and AIX, and Microsoft Windows. Getting Puppet
