Sitecore Enterprise Architecture for Global Publishing

Sitecore implementations with Content Delivery nodes in multiple locations must keep their databases and content in sync. The Sitecore Scaling Guide summarizes areas of concern, such as isolating CM and CD servers, enabling the Sitecore scalability settings, maintaining search indexes, etc. Sitecore runs on top of SQL Server, and one topic touched on in the Scaling Guide is SQL Server replication, and conveniently there is a Sitecore guide just for that specific subject. This guide explains how, with SQL Server Merge Replication, one can coordinate the content of Sitecore databases that are not in the same location. This is the starting point for what we at Rackspace have found to be a global publishing architecture that meets the needs of enterprise Sitecore customers.

PowerShell 101 from a Linux guy

Having spent my last 7 years concentrating mainly on Linux® and related technologies, I spent 3 days with PowerShell and here are the some observations and anecdotes. Why PowerShell? Curiosity for one and I wanted to learn it from a perspective of how to use it in configuration management tools like Chef. As an disclaimer, I’m not an expert in PowerShell and spending 3 days is just scraping the surface but I did learn quite a bit in that time. Also my prediction is that PowerShell will be real force (if not already) in Windows environments. It is a mindset change for several Windows administrators who have grown up on GUIs but that is about to change in the coming years. And if you are Linux administrator, you are likely to feel more comfortable interacting the PowerShell way. I definitely did.
