allow changing instance size of web role (extra small, small, ...) through the management portal without having to redeploy the application

I would like to easily 'donate' my unused CPU cycles towards a good cause, such as cancer research within the Folding@home project.

Ideally this setting would be incorporated into the config of my worker roles, or within the Windows Azure portal.

In Azure CDN, there should be option to clear cache.

With the shown lack of security and adequate data protection / backup through the sidekick issue, security should be the focus of Microsoft with Azure. It can't be full proof I know, I am nervous about cloud computing in general...

It would only require one server side call to obtain SAS(Shared Access Signatures) to get access.

The library could also support parallel uploading for fast uploads!

From Visual Studio I would like a well integrated remote debugging experience with Windows Azure Cloud Services. This is a good start, but it would be extremely useful to have this integrated in to Visual Studio 2012.

SQL Azure Database does not support distributed transactions, which are transactions that multiple transaction managers (multiple resources). This means that SQL Azure doesn’t allow Microsoft Distributed Transaction Coordinator (MS DTC) to delegate distributed transaction handling. Because of this you can’t use ADO.NET or MSDTC to commit or rollback a single transaction that spans across multiple SQL Azure databases or a combination of SQL Azure and an on-premise SQL Server.

Have the ability to flag an input endpoint as public (today) or private (accessible only within service). Private input endpoints would differ from internal endpoints in that they are load balanced so users don't need to create there own load balancing mechanims.

As what we can do with Azure Website.

Today there is no way to understand who was added to a subscription and who added them basically the audit trail is missing , it is a support call when this should be self service information . This is question being asked over and over again by audits like FISMA, ISO etc.

At least with GIT is not yet possible to setup deployment from a private repository

For Live Id, ACS should provide at least the same claims as Live SDK, so it could be really used as a federated IdP. Now, if I want a claim for user email, I can use the ACS for facebook, google and yahoo, but not for Live! This way ACS just loses it's main purpose.

To protect the data in table storage against human and application errors it would be great if it was possible to take incremental snapshots of table storage into blob or another storage account.

GPU computing will definitely give a perfomance boost for High Performance Computing. Amazon already offers this service so i thing Azure should provice a relevant service

If user want to get hosted service DNS then using IP he/she can able to find DNS. As you can see in my case http://stackoverflow.com/questions/10612295/how-to-get-dns-name-from-rest-service-which-is-consumed-by-startuptask-of-azure/10622625#10622625
I would like to get details of DNS of webrole application but nslookup shows me that it doesn't exist. Using this somehow user can process on DNS and do some logic. In my case i would like to detect staging vs production using DNS without certificate & management API

One may need to CRUD to multiple databases in a single transaction. If a user action generates multiple rows, in a scalable architecture like Federation, due to the randomness of GUIDs, rows will be distributed among several databases. We need the ability to rollback changes to any DBs if a CRUD operation on a table fails.
