Question: “How does an admin protect their SharePoint farm from poorly written custom code?” Answer: “Force custom code to run in the SharePoint sandbox mode.” Not quite! Turns out that running in a sandbox mode (as the name suggests, it is a restricted execution mode within SharePoint) is not very productive because of the performance penalty and very limited capabilities available to code running in it. A better approach is to move the code “outside” of SharePoint and into a “private” execution environment (so that the errant developers can shoot themselves in the foot, but not everyone else).

During this discussion I talk about how the cloud influences application design, focused on more asynchronous, scalable and flexible messaging focused architecture. While the patterns could be applied to any cloud technology, Microsoft Azure is particularly well-suited to these architectural patterns, providing services that cover each pattern approach for optimal results.

Our first presentation date is Wednesday, January 29. You won’t want to miss this session, as we’ll cover both updates to Azure and new ways to extend your data center.
In this session we will share an example Platform as a Service (PaaS) Web Role workload in Azure. This workload will help you understand how Azure constructs can be used in support of different scenarios.
The workload we’ll discuss makes use of the following Constructs:
“We want the cloud to be a seamless extension of our data center, not a walled garden. We want to use our existing IT setup and tools to manage on-premises and cloud-based applications.”
“We want to seamlessly move virtual machines from on-premises to the cloud and back.”
“We want to move existing applications to the cloud without the need to change the applications in any way.”
…then our upcoming Introduction to Windows Azure IaaS session is for you.
This free half-day session is for anyone who wants to better understand the Windows Azure Infrastructure as a Service (IaaS) offering. After a brief overview of the Azure Platform as a Service (PaaS) model, we will focus on key IaaS concepts. Additionally, we will walk you through a number of scenarios enabled by Azure IaaS and several demonstrations. Learn about the new generally available features including virtual machines (with more size options), virtual networks, new image types (including SQL Server and BizTalk), lower pricing and much more.

In other words, automate every aspect of your (cloud-based) infrastructure.
Given AIS’ years of experience with SharePoint, we are always looking for ways to make the underlying infrastructure more cost effective, scalable and robust. Fortunately, the benefits of automation apply equally to a SharePoint 2013 farm hosted in the cloud — whether it’s the ability to dynamically provision a SharePoint 2013 farm on the fly, or the ability to scale up and down based on load, or the ability to make the SharePoint 2013 farm more fault-resilient.
We’ve written about two automated deployment approaches to SharePoint 2013; one for Amazon Web Services and one for Azure. In case you missed them…
Our work with Rolling Stone and Bondi Digital Publishing is yet another example of how AIS can develop technology that creates new revenue streams for publishers. We built a digital distribution platform to usher print publications like Rolling Stone into the digital age – by providing them with a turnkey solution to deploy print magazine archives online for viewing on desktops, laptops and mobile devices. For Rolling Stone, the initial launch included more than 1,000 issues from 1967 to the present.
This announcement also represents a major chunk of Microsoft’s family of Azure offerings…and in my opinion, a stepping stone many companies simply must take in moving out of the traditional data center and into the cloud. The following diagram shows the stepping stones out of the traditional data center:

Notice anything missing?
Everything is in the “System.Web” namespace, meaning that all of this is framework code and not application code. This begs the question: Why is this happening?
Apparently, something in the framework (which was indirectly affected by our app) was causing this.
After many, many weeks of on again, off again debugging, I finally discovered the problem:
