Create certificate for - Windows Azure Service Management API - Authentication

I was tried to access my Azure Hosted service”, using Windows Azure Service Management API. This just released (september 2009) API, currently doing authentication using

From MSDN,

Any valid X.509 v3 certificate can be used for authentication. You can use a self-signed certificate or one signed by a certificate authority.

To access our “Azure Hosted service” using “Azure Service Management API”, we need to upload our Certificate certificate file (*.cer) to the Azure Portal. [this kind of authentication may be changed by Microsoft, since this API is now in earlier version]

Some Useful links about “creating Certificate file”:

  • Using MakeCert.exe : from msdn link
  • Using IIS to generate a X509 certificate : from Eric Nelson’s msdn blog link

Azure Hosted Service Manger Tool

Currently Cerebrata company, is in process of creating WPF based tool which uses this API. Once screenshot of this tool for view.


I will update about this application in later post.

Azure Contest – Jaiho application

Around one and half month back, I came to know about in NewCloudApp() developer challenge. It was a contest for creating Windows Azure based web application (or) service. I participated in that same [In 'international category'] with hearty support from my friend Ashok. Created a application called "Jaiho" and hosted here.

Now the contest is completed, congrats to the winners. My application is not selected, however thanks to all who tried the Jaiho application and voted for this.

About application "Jaiho" application:

Initially we planned to implement  many functionalities for this website as like “big social networking website” like Facebook, Orkut.

Due to time limit, and laziness only few functions were implemented while hosted for contest.

Currently following functionalities are in this application,

  • User can create an account newly  (by new username, password)  (OR)
  • User can also create account by other web 2.0 website’s username password (OpenID / OAuth based User Authentication)
  • Anyone can do “Search operation” by “myBing” section [it is using Bing search engine’s API]
  • After creating account, user can store any files into this website (internally storing the data in Azure Blob storage)
  • Currently all uploaded files accessible to public (will be changed, based on user choice)


I missed to post the details about “Jaiho” in this blog. Here below the excerpt of the mail which I sent to friends to promote this app for voting. Please Note: this below image is also hosted in cloud (by my account in Jaiho application). (i.e) image URL is:

Update (05-Nov-2009):

Recently got notice from Microsoft, as I have to shift all my application/storage data to anther “region”, and previous data will get deleted. Excerpt of that notice is as follows:

“You are receiving this mail because you have an application or storage account in Windows Azure in the “USA - Northwest” region.  Windows Azure production applications and storage will no longer be supported in the ‘USA-Northwest’ region.  We will be deleting all Windows Azure applications and storage accounts in the “USA - Northwest” region on November 3rd.”

So, currently this basic application is down

Few bits about Cloud Computing & Microsoft Azure Platform

Cloud Computing  &  few bits about Microsoft Azure Platform,

Cloud Computing

[From wikipedia, ( )]

Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet.

Leading companies offering Cloud Computing services, including:

  • Amazon
  • Google
  • Microsoft



Google App Engine  -

Allows to host application written in  Python  & Java


Azure services platform. Windows Azure -

Allows to host application written in ASP.NET  & PHP

Java applications can also utilize “.NET services” by separate SDK

We can create, test and debug the applications using Visual Studio


Windows Azure Service Platform

Windows Azure is the cloud services operating system that provides various functionality for Cloud Computing. It serves as the development, service hosting, and service management environment for the Azure Services Platform. Windows Azure provides on-demand compute & storage services on the Internet in Microsoft data centers.

It provides various services including,

  • .NET Services
  • Azure Storage Services
  • Live Services
  • SQL Data Services.

Azure Storage Services

  • Windows Azure Tables
  • Windows Azure Blob
  • Windows Azure Queue

Windows Azure "Tables"
- Used for "DBMS like" functionality. provides scalable, durable structured storage in the form of tables. The tables contain entities, and the entities contain properties.  support ACID transactions. It can be accessed as "REST programming approach" via "ADO.NET Data Services".

Windows Azure "Blob"
- Used for "storing Binary data" (ex, Photos, Videos any any type of files). 

Windows Azure "Queue"
- provides reliable storage and delivery of messages for an application.



Microsoft .NET Services

- set of developer-oriented services that provide key building blocks "for communication among applications".

[Much like the .NET Framework, for the Cloud computing].

  • Access Control Service
  • Service Bus

Access Control Service
- The Access Control Service is a cloud-based "Security Token Service (STS)". It provides way for standards-based identity checking.

Service Bus
- provides the familiar Enterprise Service Bus application pattern.



Live Services

- is a set of building blocks for handling "user data and application resources". Live Services includes Mesh technologies for synchronizing user data and extending Web applications across multiple devices.
