Why immutable infrastructure?

Abstract:

I'd like to present the evolution of infrastructure up to the modern day: from big physical snowflake-like servers to the modern immutable and disposable containers.

During this ignite talk I'd like to answer the following questions: * Why have we ended up with immutable infrastructure? * What are the challenges for the system administrators when moving towards immutable infrastructure? * What are the benefits? * Why can't we just continue reusing the servers/VMs like we've got used to? * How immutable infrastructure influences Continuous Delivery process?

Speaker:

He has helped more than a dozen customers to assess and improve their release/deployment processes, and run their applications better in production.
