NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions it is likely that it is still relevant. If the blip is older it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the RadarUnderstand more

Precedents set by cloud providers are now changing expectations within the corporate datacenter. In the cloud, many systems scale automatically, either to provide additional availability or in response to increased demand. Crucial to managing a growing estate, immutable servers, or ‘phoenix servers’, are a sensible approach for enterprises looking at IaaS and PaaS. In contrast, custom-configured ‘snowflake servers’ increase the load on the operations group and encourage a “works on my machine” mentality. Being able to re-provision machines - hard or virtual - from scratch using tools such as Chef or Puppet can drastically reduce the complexity of managing large server farms. Coupled with software that is designed to withstand failure, this will lead to more scalable and reliable systems.
