Case study:
Rackspace operatesa customer’s
OpenStack estate
A global web service provider with 280,000 physical nodes of OpenStack
private clouds turned to Rackspace to take over its OpenStack estate
while its team turned its attention to building out a public cloud strategy.
Rackspace offered a dedicated pod approach staffed by more than 20
Rackspace engineers working on the customer’s laptops inside its systems.
This approach was designed to create a seamless experience for application
owners. The Rackspace team is now operating the customer’s OpenStack
workloads independently.
Case study:
Rackspace helps modernize a customer’s
OpenStack environment — with
zero downtime
A scientific organization, that has been an OpenStack customer with
Rackspace for over a decade, needed to modernize its OpenStack
environment to enhance the resiliency, reliability and functionality of its
private cloud. The organization used Rackspace Elastic Engineering to
support a minimum viable product (MVP) upgrade that moved the system
forward through several OpenStack versions — in less than a year with zero
downtime. Rackspace engineers also helped convert the organization’s
networking topology to single-bond LACP, cutting the number of switch ports
needed in half, which allowed for higher rack density and significant savings
on data center costs.
