Common Web Farm Deploymentwww.contoso.comwww.contoso.comwww.contoso.com

Pros and Cons

ProsSimple solution.Good for scaling-out a dedicated/homogeneous environment.

ConsNot appropriate for shared/cloud deployment with many customers.Difficult to scale-up to achieve high site-density.

Elastic Scalability

NUMA Scalability

Basic commodity server in 2014:16 to 64 logical cores.NUMA architecture.64GB RAM.40Gbit NIC. $300-$1500 w/o OS.

High end server:256 or 512 logical cores.

Non-Uniform Memory Access (NUMA)NUMA Concepts

-Groups of processors associated with local memory

-Accessing non-local memory is slower-NUMA nodes vs. Processor Groups

IIS changes to support NUMA-Added second processor mask to support > 32 cores

-Automatic Configuration- Set maxProcesses="0"- Will set 1 process per NUMA node
