Microsoft Web Farm Framework: Microsoft Web Farm Framework

Microsoft Web Farm Framework

Microsoft Web Farm Framework for IIS7 enables administrators to provision, scale and manage their web infrastructure

Microsoft has released Web Farm Framework Beta, which enables us to easily provision and manage a farm of web servers. It enables to automate the installation and configuration of platform components across the server farm, and enables to automatically synchronize and deploy ASP.Net applications across them. It also supports integration with load balancers, enables to automate update across our servers so that our site/ application is never down or unavailable to customers.
Web Farm Framework can be used to :
  • Provision web platform and content
  • Scale web infrastructure and resources using ARR and 3rd party load balancers
  • Manage multiple servers or a farm using a unified interface

Using Web Farm Framework to Provision and Scale a Web Farm
The Microsoft Web Farm Framework enables you to easily define a “Server Farm” that you can add any number of servers into. Servers participating in the “Server Farm” will then be automatically updated, provisioned and managed by the Web Farm Framework.
What this means is that you can install IIS (including modules like UrlRewrite, Media Services, etc), ASP.NET, and custom SSL certificates once on a primary server – and then the Web Farm Framework will automatically replicate and provision the exact same configuration across all of the other web servers in the farm (no manual or additional steps required).
You can then create and configure an IIS Application Pool and a new Site and Application once on a primary server – and the Web Farm Framework will automatically replicate and provision the settings to all of the other web servers in the farm. You can then copy/deploy an ASP.NET application once on the primary server – and the Web Farm Framework will automatically replicate and provision the changes to all of the web servers in the farm (no manual or additional steps required).
The Web Farm Framework eliminates the need to manually install/manage things across a cluster of machines. It handles all of the provisioning and deployment for you in a completely automated way.
Load Balancer Integration
In addition to making it easy to provision/deploy servers and applications, the Web Farm Framework also includes load balancer integration. Specifically, the Web Farm Framework can integrate with an HTTP load balancer so that as web servers in the farm are updated with changes, they can be automatically pulled out of a load balancer rotation, updated, and then added back in. The Web Farm Framework can also optionally update the machines one at a time – so that you always have servers available to handle heavily load. This enables you to keep your site always available during updates – without you having to write any manual scripts to control or manage the update roll-out.
The current beta of the Web Farm Framework includes built-in support for the IIS Application Request Routing (ARR) service (which supports automatic load balancing of HTTP requests across multiple machines in a web-farm). The Web Farm Framework makes it really easy to integrate your web farm of servers with ARR for load-balancing, and includes the support to automatically pull a server out of rotation as it is being updated, and then have it added back into rotation once the update is done.
The final Web Farm Framework release will enable extensibility with other load-balancing technologies as well – enabling the same ability to automatically pull/inject servers from a load balancing rotation as they are updated.
