McKesson runs a "huge array" of apps on its internal cloud for business processes such as new employee requisition, board meeting management, and compensation management, says CIO and CTO Randy Spratt.
On the SaaS front, the healthcare services company is in the process of converging multiple Salesforce.com deployments into a single instance.
On the infrastructure front, McKesson spent about a year piloting a converged infrastructure appliance before launching it into production. Today the appliance runs about 1,200 virtual machines, and a business-facing broker layer lets IT choose either a private, Amazon or Azure deployment model depending on the risk profile of the system.
Looking ahead, McKesson’s next major pursuit is full hot-hot disaster recovery capability, spreading the cloud across two data centers. At that point, McKesson will be close to migrating its legacy apps from current environments as they depreciate to zero value and building apps on new environment, Spratt says.
