- In addition to the rapid growth of the Internet, more and more enterprise applications are moving to a web model. However, servers are still critical to the business because of the applications organizations run on them, from email to accounting to line-of-business applications. Key business drivers that call for an open web and application platform include:Managing web applications and resources optimallyOperating flexible and dynamic datacenters across premisesReusing development skills and trainingProtecting and gaining leverage from existing investments and infrastructureScaling on demandWindows Server 2012 is an open application and web platform for the datacenter and the cloud.
- What’s more frustrating than watching your browser’s spinning cursor when a website isn’t ready? With Internet Information Services 8 Application Initialization, most web applications respond instantly to the first user’s request. If an application isn’t ready, Internet Information Services can intelligently choose a static web page to show the user while the application starts.With Application initialization, you have two configuration options:Configure Internet Information Services 8 to initialize the application on-demand when it receives the first live request.Configure Internet Information Services 8 to send a request to the application immediately after Internet Information Services starts. This request simulates a request from a user to a page that you specify, causing ASP.NET to compile the application (if necessary) and then start it. Application developers can create custom pages designed specifically to initialize all aspects of an application.You can configure Internet Information Services 8 to return static content, such as an HTML page, as a placeholder or splash page while ASP.NET starts the application. You also can use the Internet Information Services URL Rewrite Module to provide different static pages based on the specific URL requested by the user.Application Initialization feature is configured through a combination of global rules (using the applicationHost.config file) and application-specific rules (using the web.config file) that tell Internet Information Services 8 how and when to initialize web applications.
- Earlier scenarioIn previous versions of Windows Server, there were ways to manage the memory, network, and disk size—but not input/output—per the Internet Information Services application pool.With Windows Server 2012 Windows Server 2012 Internet Information Services introduces CPU throttling. CPU throttling can be used to set the maximum CPU consumption allowed per application pool. Because the recommended setup is to create a separate application pool (sandbox) for each tenant, administrators can use CPU throttling to prevent one tenant’s application from monopolizing CPU resources needed by other tenants. In Internet Information Services 8, each tenant is an Internet Information Services worker process.The sandbox (application pool), ensures a high level of service for each site. The feature also can be used to create a new business model in which a client that pays more gets higher limits on the resources on the server.Hosters, especially those that are in the shared hosting business, will try to run as many customer sites on the same resource as possible (hence “shared” hosting). You also may hear terms such as multitenancy(meaning, there are multiple customers on the same resource) or site-density (many tenants on the same resource). When you have a multitenant environment, you will want to ensure several things, including:Security (one tenant cannot see another tenant’s shared resource) Resources shared (ensuring that each tenant gets a “fair” share of the shared resource without monopolizing all the resources and negatively impacting other tenants on the same resource)This particular feature is about resource sharing, where a resource can be any one of memory, network bandwidth, disk space, and of course CPU. Windows 2012 (or Internet Information Services 8), offers the capability to configure how much CPU each tenant can consume. It provides that “protection” (such as preventing one tenant from monopolizing all the CPU cycles), and also opens an interesting business model for hosters. They can start to monetize CPU cycles by segmenting their customers (for example, bronze customers get x% of CPU, silver customers get y% of CPU, and gold customers get z% of CPU). When it comes to resource throttling, there are largely two concepts. One is called reservation, meaning x% of CPU is dedicated for a given tenant. The other is limitation, meaning a tenant cannot use more than x%.How you use this particular feature is important to understand, because hosters typically over-subscribe their tenants. From a technical point of view, the throttling limit is set per process. In Internet Information Services, each tenant is a process (that runs in a separate identity) and thereby provides a process boundary between each tenant. To use Internet Information Services terminology, in a shared hosting environment, the best practice for deployment is to create a separate and dedicated application pool for each tenant. And because each application pool runs in a separate process, and because we can apply the throttling limit per process, we can accomplish imposing the limit per tenant. In a more technically detailed way, the way we manage the CPU limit is to manage the scheduling of the threads (for a given process) in such a way that they don’t get scheduled after the limit is met.
- Protects servers from denial of service attacks by automatically blocking potentially harmful IP addressesDynamic IP address filtering and blocked access are based on:Specified number of requestsNumber of connection attempts during a specified periodSpecifies action to take when Internet Information Services blocks requestsLogging Only Mode helps to determine potential impact for legitimate usersCan be configured as:Static rule based on a client’s IP addressDynamic rule based on heuristicsWith Internet Information Services 8, you can set up filters to automatically block potentially harmful IP addresses. Dynamic IP restriction is an optional feature that must be explicitly installed through Server Manager.Administrators can use dynamic IP restriction to do the following:Block access for IP addresses that exceed the specified number of requests.Block access based on the number of connection attempts from an IP address during a specified period.Specify the response when Internet Information Services blocks an IP address. For example, requests from malicious clients can be aborted by the server instead of returning HTTP 403.6 responses to the client.Use a new proxy mode (Logging Only Mode) that allows IP addresses to be blocked by the values that are received in the x-forwarded-for HTTP header in addition to the client IP that is seen by Internet Information Services.Use Logging Only Mode to assess the impact of enabling dynamic IP restriction, which gives the ability to determine whether settings would impact legitimate users.

- Windows Server 2012 provides the flexibility to build symmetrical and hybrid applications on-premises and in the cloudProgramming symmetry between on-premises and cloud environments provides the ability to use the same development model for Windows Server 2012 and Windows Azure. With programming symmetry, developers can work in a single, unified environment to build solutions that can focus on either Windows Server or the Windows Azure cloud platform. These programming tools can be used across web, application, and datacenter tiers for locally deployed applications and for private and public cloud solutions.Common development tools. Microsoft Visual Studio and Microsoft Team Foundation Server provide a rich development experience and offer to .NET developers a complete environment to build cloud and on-premises applications.
