· Portal: The new HTML-based management portal
· Windows Azure Web Sites: a new way to run web sites in the cloud
· Cloud Services: new and expanded services for Platform-as-a-Service (PaaS) use of the cloud
· Virtual Machines: a new Infrastructure-as-a-Service (IaaS) offering in the cloud
Windows Azure is now a 3-Lane HighwayThose last three items are the modes in which you can now use the cloud: supremely managed, highly managed, or self-managed. Web Sites allow you to run web sites in the cloud without having to change the way you do things now, and with no cloud-specific artifacts to deal with. Cloud Services are the new name for the traditional Windows Azure PaaS Service Model. Virtual Machines provide a self-managed capability where you directly create, configure, and compose persistent VMs. We’ll go into each of these ways of using the cloud in Parts 2, 3, and 4.
Three Modes for using Windows AzureThese three modes of use make Windows Azure the broadest cloud platform in the world, with something for everybody. Those who “just want it work” without having to do direct IT will love Windows Azure Web Sites. Those who like managing everything themselves (you know who you are) will prefer Virtual Machines. And Cloud Services, the original PaaS model, strikes a nice balance between the two: a high level of automated management with the versatility to support many different kinds of applications.
The New Portal: Cloud Computing meets Couch ComputingThe new Windows Azure portal is HTML-based – a big departure from the prior Silverlight-based portal. This change broadens its reach, allowing it to be used on tablets such iPads or Windows 8 slates. This means you can be managing your cloud assets pretty much anywhere as long as you have connectivity. I can be on the couch or even outdoors with my iPad3 4G and monitor and manage my cloud assets when I need to. Now you can have a life and still responsibly oversee your IT.
The new portal has a clean and attractive design and delivers a superior user experience. Its styling looks to have been inspired by Windows 8 Metro principles.
New Windows Azure PortalCommands and Notifications
The portal has a command bar at bottom, showing available commands, and a notifications area for status and error messages. Notifications can be hidden or expanded, and they stack.
Command Bar with Notifications ExpandedThe new portal is a major improvement in usability, and it also plays an instrumental role in several of the new features such as monitoring analytics and in-cloud VM composition.
Monitoring DashboardIn the past, if you wanted to monitor your cloud assets it was up to you to set up diagnostic monitoring in your application, usually by leveraging the Windows Azure Diagnostics system. Although this facility is very powerful, it requires you to take steps to configure it in your application and doesn’t include a way to visualize the data that is collected.
In the new portal, monitoring of core metrics is automatic. Use of Windows Azure at any level (Web Sites, Cloud Services, or Virtual Machines) includes built-in monitoring and the portal nicely displays metrics as shown below. The display is interactive: you can change the time scale and which data points are displayed.
DashboardThis new built-in monitoring facility doesn’t do away with Windows Azure Diagnostics: WAD remains important for capturing a broad variety of metrics including event logs, performance counters, IIS logs, crash dumps, trace logs, and application logs. As useful as that is, it’s fantastic to bring alongside it built-in monitoring, something you don’t have to enable, that’s there for you when you need to know what’s going on with your cloud deployments.
ImplicationsWindows Azure has grown up. Often newer technologies bring benefits and innovation as well as rough edges and pain points in the early days, forcing prospective users to carefully weigh the pros and cons. Cloud computing has been no exception. Windows Azure has reached a milestone and isn’t just for early adopters any more. I look now at Windows Azure, as compared to its debut in late 2008, and I’m supremely proud of how far it has come. It provides significant value that nearly all organizations can benefit from; its development and management experience is excellent; its breadth of capabilities is unmatched; and its multiple modes of use accommodate, rather than frustrate, a variety of IT preferences.
