Disclaimer: this post and the next ones are early drafts to share with you the direction we are taking. They might (and I hope they will) change quite a bit in the actual Guide! We might end up not covering one of these scenarios in the book. These posts...

As I mentioned in my previous post , we are going to use a “case study” approach in this book in which we will be presenting a series of concrete scenarios, each one will introduce some very specific requirements. Then we will be showing and discussing...

For the next couple of months I’ll be working on a new project here at patterns & practices , developing a new guide for claims based authentication and authorization. I’m personally very happy to be working on this project, for many reasons. I believe...

Windows Azure’s primitives are very simple, but as in many other things, the power comes from the combination of these simpler primitives to create more complex things. Look around and see how many things can be assembled from a little more than 100 ...

Provisioning IssueTracker Enterprise: Highlights: There’s no direct interaction with Access Control Service. IssueTracker uses ACS API to create the scopes, rules and the issuer (Contoso). The provisioning form captures all the required information to...

Having solved the identity issue, the SuperCloudySoftware team focuses then on the management requirements raised in the meeting with VeryBigCorp CIO. To recap, they want to: Be able to to monitor IssueTracker from their existing infrastructure, that...

In the previous article , we explored the challenges of building services for an enterprise, illustrating those through a dialogue between VeryBigCorp CIO and a team from SuperCloudySoftware . VBC requirements can be summarized as: Identity integration...

In his latest post on Coghead’s demise, Phil argues that: “ What this highlights is the lack of any standard for transferring not just data but application logic between such platforms.” My argument is that those standards already exist and are widely...

Actors : the CIO at VeryBigCorp , John ( SuperCloudySoftware's CEO) and a bunch of senior developers and architects. CIO : Gentlemen, welcome. Let me start by saying that our internal Customer is absolutely fascinated with your application. Believe...

Now that we have introduced our characters, we will start this story describing the acquisition process of IssueTracker in VeryBigCorp . IssueTracker was first used in VBC by a very limited number of people. Someone in some business unit somehow learnt...

I will start this series by introducing the main characters of our scenario. First, we have VeryBigCorp . VBC is a large corporation, with multiple branches and subsidiaries, thousands of employees, etc. VBC is the typical organization with a rather...

I've got like 5 posts in my queue. All of them are drafts, all need work, all need nice graphics to illustrate the concepts and all are related to my session at PDC . I'm 100% focused on actually having all my demos finished, deck's polished, etc. and...

About a year and a half ago, some proto-ethnologist started a tagging blogo-game:  you where asked to write 5 facts about you and then tag 5 other people you knew. Not sure if someone eventually did any analysis of the spread, lifetime and reach...

Sinclair Schuller , CEO of Apprenda was kind enough to demo SaaSGrid to me earlier this week, patient enough to answer all my questions and I have to say, that I'm really impressed. What is SaaSGrid? In their own words: If you're building an on-demand...

A common concern with SSDS, and a common question I get in many presentations I've given is how to handle concurrency and entity versioning. Suppose you have the following sequence of events: By default, SSDS will just accept the last Update and overwrite...

When we implemented claim based authorization in LitwareHR, we had to write a lot of code and play with non-trivial configurations (LitwarehR includes 2 STS and all the supporting infrastructure for securing the web services and the callers to them)....

I just uploaded the source code for this library, used in the Virtual Earth mash-up described in my previous post . You can browse/download it from here . What you will find: A simple domain model for GeoRSS feeds with support for points , lines and polygons...

Tim Jarvis raised a good point in my post on cross-container queries which is: how to handle paging? SSDS currently supports a very simple paging pattern that uses the entityId . By design, the first 500 entities will be returned, but the entities will...

Here's an end-to-end demo of LitwareHR using SSDS. The total demo lasts about 11 min and you will see: Tenant Provisioning and customization (takes the first 5 min approximately). I show the initial tenant provisioning (creation of a new tenant...
