Microsoft's many Entrances to the Cloud
Microsoft Office Live Workspace MOLW
Microsoft Office Live Small Business MOLSB
Microsoft Windows Live SkyDrive
Microsoft Live Services MLS
Microsoft Live Mesh MLM
Over the past three years Ray Ozzie changed the culture of Microsoft to one where the company behaves more like a startup company than a giant in order to quicken the pace of releasing new products and services.
Previously, a big part of any development team at Microsoft was making sure its new product worked in lockstep with everything else the company produced. This "unification" criterion was something that Bill Gates had always hammered on.
Now Ray Ozzie pushes the developers to rush ahead and build new things without waiting for integration, unification and convergence. The result is a variety of brand new cross-over products that confuse the consumer. This problem is amplified now due to the nature of the “perpetual beta” where it’s socially acceptable to release preliminary beta versions for apps or services.
Consequence: Microsoft's different Office developer groups and different Azure teams offer their own gateways to the cloud and behave as small competing companies as real competitors do.
See: James Senior Blog.
The Google way is far more experimental: Google dumps a lot of competing free trial software on the market and observes whether somebody is interested in. When there are users, they will soon detect that this is just a preliminary test balloon. Such users will complain about quality and when many users complain it's a reliable proof of use and public interest.
Anyway, such practical market analysis pushes Google's reputation to be a creative company.
MOLW offers 5 GB of free cloud space. It's a service of the Office Live service portal bit it isn't restricted to Microsoft Office users nor to Office file formats.
The space can be shared with anyone. Many authors can work within one document and there is an automatic synchronization service.
Whatever you upload with MOLW you will see it when you check in later under the same Windows Live ID in Live Mesh (see below).
Probably MOLW will merge one day with SkyDrive and later with the final release of the more powerful Live Mesh.
See: Wikipedia/Office_Live and Microsoft Office Live Workspace beta.
MOLSB extends MOLW by a free one-year website hosting and email service.
The free service just includes a fourth level domain such as www.myName.web.officelive.com.
A second level custom domain such as www.myName.com can be booked at $ 14.95/year (in Germany: http://smallbusiness.officelive.com/de-DE/pricing).
Additional cloud space and users are also available, but MOLSB doesn't support any server side scripting such as PHP, ASP, ASP.NET, SQL nor any other database, not even Microsoft Access.
Advice: You have to deactivate MOLSB's annoying web design tool when you want to host arbitrary HTML-, and PDF-web content.
SkyDrive is a file storage (25 GB free !) and sharing service. It's a service of the Windows Live service portal, but it's available outside of Windows too. Sooner or later Microsoft will merge MOLW and SkyDrive with Windows Live.

Windows Azure is Microsoft's new cloud services operating system = "Windows in the cloud".
It is called a platform because it offers all necessary developer-, hosting- and service-tools to write and run cloud applications.
→ Windows Azure Platform Developer Center
→ Introducing the Windows Azure Platform
→ Introducing Windows Azure
|Single user view:||Azure is the internet portal Live Mesh which is a modernized mixture of the internet portal Office Live plus the portal Windows Live.
The user is allowed to write into and to read from his free 5 GB cloud space and to synchronize the files among all of his computers, PDAs and mobile phones.
Drawback: The user is restricted to an Azure subset called Live Services.
|Business view:||Azure are Live Services plus SQL Azure Database aimed to shift internet business into the Microsoft cloud.|
|Programmers view:||Azure is a layered set of services, SDKs and tools for writing Mesh-Enabled Web Applications.
1. The basic layer are the Windows Azure Services, with their SDK and the Tools for Visual Studio.
2. The second layer contains:
2a: Live Services and the developer tools of the coming version of Windows Live SDK.
2b: .NET Services and the .NET Services SDK.
2c: SQL Data Services (SDS) + SDS Library.

The future of Microsoft Windows and Office
The next Microsoft operating system after Windows 7 will probably integrate the complete Azure services. Consumers will write into and read from the cloud; they will not need harddisks. Application programs and games will mutate to cloud services. They are not bought and installed anymore. All Microsoft Office programs will go this way. Their basic use will be free but stuffed with advertising while power users and companies will be charged by call, volume and velocity.
Live Mesh is the answer to a multi-device world where people have a notebook, a laptop, a home PC, a Media Center and a SmartPhone and have difficulties to keep everything in sync.
The answer combines several ideas:
1. The glue between all those devices is the internet.
2. A "Unified Device Management" makes the devices work together.
3. A "Unified Data Management" makes the data available from anywhere .
4. A "Unified Application Management" makes the applications available from anywhere.
5. A "Centralized Management" is a place where you could remote control your devices from anywhere.
6. The Live Mesh GUI runs in any browser.
7. You must access your Live Mesh via your Windows Live ID.
8 . When you upload a file or a folder it automatically replicates and downloads to all other devices in the Live Mesh.
9. You can share all or parts of your Live Mesh with friends.
Caution: Live Mesh still is Beta-stage-software.
The experience with Microsoft products is that when they are released in Beta they are usable or quickly get to the point of being usable. Live Mesh Beta isn't there and it doesn't seem to get there soon. It works quite nicely but it's GUI and behavior often is illogical. A good list of bugs can be found here: Known Issues.
Such issues are:
- Live Mesh doesn't cooperate with MOLW, MOLSB and SkyDrive.
- There is no fine-grained control over which files and folders Live Mesh syncs, and where.
- Files cannot be be edited right on the Live desktop.
- It doesn't sync Outlook.pst files.
|Thus Live Mesh is much more powerful than Microsoft Office Live Workspace or SkyDrive.|
It offers a free 5 GB cloud space ( = the mesh) together with sync-, share- and remote access-services.
Unlimited unrestricted space can be synced by opting out big files of being copied into the cloud (= peer-to-peer sync).
On any computer Live Mesh installs a beautiful virtual desktop GUI called the Mesh Operating Environment MOE, written as RIA in WPF together with a sync program.
The sync program installs in Windows Explorer an additional line into the right click menu when you select a folder : Add folder to Live Mesh....
After uploading the folder into the cloud, the directory icon turns blue to indicate the folder as being synced.
From now on the folder has another line in its right click menu: Live Mesh Options which expands to a second slide out menu that offers 4 command lines:
Change sync settings..., Invite members..., Manage members... and Delete folder....
After setting up Live Mesh on all of your computers, your synced folders and files will appear on all of them.
You connect to the MOE using the Mesh task bar icon or through www.mesh.com.
After logging on, you are presented with your synced folders so you can access any of your files through the web or you can transport yourself to another computer that is set up in your mesh.
Live Mesh Remote Desktop opens a window in the computer you are currently using and gives you access to even those folders you haven’t synchronized.
Try to copy and paste files between your remote computer and your local computer.
The remote window will appear exactly as your desktop looks including your desktop icons, taskbar and any opened windows or programs.
You use the remote desktop as you would normally use your desktop as if you are directly in front of your computer.
This comes in handy when you need to use a program on your home or office computer that is not available or installed on the computer where you are located.
You can also select a file on your computer that is not currently synced and drag it into a synced folder. This service is cool.

|There are 3 bundles of services:||Azure Services contain Live Services contain Mesh Services|
and programming Mesh Services is the core of cloud programming.
|Azure Services (highest)||all Live Services + .NET- + SQL Services|
|Live Services||all Mesh Services + Identity- + Directory- + Storage-Services|
|Mesh Services (basic)||Users- + Devices- + Applications- + Synchronisation-Services|
Platforms and Services
The term "Platform" means a set of services plus a developer environment to link these services together and to write user interfaces which present everything to a customer.
Both Azure and Live Mesh (both in Beta stage) are said to be "Platforms" because they offer bundles of cloud services together with Visual Studio tools. They share a common foundation of services but Live Mesh (being just a subset of Azure) already has a beautiful ready-to-use GUI around its Live Services.
The more powerful Azure platform has no such GUI and developers have to write their own user interface.
|Differences between||Azure Platform||Live Mesh Platform|
|User Interface||none, open access via Java, PHP, Ruby, Unix.||Windows Mesh Operating Environment MOE|
|Offers Access to||Azure Services||Live Services, which contains Mesh Services|
|Typical Owner||company||single person|
|Scope focused on||global business||two or more computers of one person|
|Main Behavior||waiting for requests||active sync + integration of personal apps, data and devices|
|Software bases on||basic naming + registration + relay
(relay = connectivity + event binding)
|.NET Service Bus|
|Programming Tool||Azure SDK||Live Framework SDK and Tools|
|Roles||Web Role, Worker Role, Data Storage||none|

Feed Sync and Mesh Synchronisation Services
MEWA run online inside a Web Browser and offline on Windows.
A MEWA builds a rich client (Cloud-to-Client) to extend the web experiences into devices and desktop. MEWAs offer a much richer user experience than what can be delivered within the confines of a web browser. Examples: Ebay Desktop, Amazon Unbox Video Player, Live Writer Beta, Blockbuster have a downloadable rich client to complement their web offering.
The data that the MEWA-user generates/updates on the client has to be synced with the cloud so it is available when you want to access the data from a device that does not have the MEWA.
MEWAs have an integrated identity management and MEWA-users can share their data with others.
MEWAs can run:
1. from a shortcut on Windows Desktop starting MeshAppHost.exe which invokes the application offline.
2. from the web page http://home.live.com which starts a Live Mesh instance of the application online.
3. as a mixture of 1. and 2.
Software as a Service SaaS (pronounced 'sass') means software deployment via the web whereby a provider licenses an application to customers for temporal use on demand. SaaS software vendors may
a) host the application in the cloud and just download a GUI once (e.g. a browser applet) or
b) download the complete application to the consumer device, disabling it after use or
c) download a mixture of a) and b).
Example: Write Online.
