Public clouds are designed to be billed in a pay-as-you-grow model and are run by third party service providers, offering resources like compute power, network and storage as a service. One of the benefits of public clouds is that the amount of resource built into the service provider is fundamentally larger than a typical enterprise private cloud, meaning that the solution is designed to scale up and down based on demand. This model provides customers with a way to reduce operational risk and cost by providing a flexible, scalable service that is based on consumption.
Today, virtually every strategic business decision has an IT implication. Market forces continue to accelerate in every region of the world, and across every industry, putting increasing pressure on IT departments to be more responsive and help organizations stay competitive and pursue new opportunities.
With these pressures, it is no wonder that cloud computing, and its promise of delivering IT services on demand, is attractive to IT departments and businesses alike. The challenge is to realize the efficiencies and agility of a cloud computing approach while maintaining the security, compliance and control that enterprises must uphold to comply with both internal processes and regulatory requirements.
