Outages, natural disasters and unforeseen events have proved that even in a distributed architecture, you need to plan for High Availability (HA). In this entry I'll explain a few considerations for HA within Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). In a separate post I'll talk more about ...

This is a continuation of the books I challenged myself to read to help my career - one a month, for year. You can read my first book review here, and the entire list is here. The book I chose for April 2012 was: Applied Architecture Patterns on the Microsoft Platform. I was traveling at the end of last month so I’m a bit late posting this ...

If you want to be wise, watch the actions and outcomes of others. Emulate the successful actions, and avoid the actions that cause failure. That’s true in life in general - and in technology projects in specific.  I’ve worked with several clients who have created or migrated an application to “the cloud” - meaning using Microsoft Windows ...

Windows Azure allows you to write code in languages within the .NET stack, you can use Java, C++, PHP, NodeJS and others. Code is code - other than keeping things stateless, using a Web or Worker Role in Azure is not all that different from working with an on-premises system. However…. Working in a scalable, component-based stateless ...

There are multiple ways to store data in a cloud provider, specifically around Windows and SQL Azure. As part of a “Data First” architecture design, one decision vector – assuming you’ve already done a data classification of the elements you want to store – is to decide the transaction level you need for that ...

Developing in Windows Azure is at once not that much different from what you’re familiar with in on-premises systems, and different in significant ways. Because of these differences, developers often ask about the specific process to develop and deploy a Windows Azure application - more formally called an Application Lifecycle Management, or ALM. ...

As most of you know, I don’t like the term “cloud” very much. It isn’t defined, which means it can be anything. I prefer “distributed computing”, which is more technically accurate and describes what you’re doing in more concrete terms. So when you think about Windows and SQL Azure, you don’t have ...

“Git-Go” is something we say in the South that means “right at the start”. I’ve seen several applications for on-premise systems that don’t have much in the way of diagnostics - the developers rely on a debugger, the event logs on the server and client workstation, and most of all, the ability to watch the system from end-to-end. This approach ...

Current as of 08/01/2011 - Check the Resources listed below for more up-to-date information on this topic Background: Security for any computing platform involves three primary areas: Principals (users or programmatic access to an asset or other program) Securables (objects, data or programs that can be accessed) Channels (methods of ...

Most mature development shops use various code diagrams to give a symbolic representation of high-level and database code structures. Standards such as Business Process Model Notation (BPMN), Entity Relationship Diagrams (ERD) and the Unified Modeling Language (UML) are a few I use all the time. In the Distributed Computing (Cloud Computing) ...
