66 “Front-end web servers that host an e-commerce online store are also good candidates,” he says. “E-commerce web servers are outward-facing anyway, so there’s really no reason to run them internally.” Marc Jones, vice president of product innovation for SoftLayer, a cloud company acquired by IBM last year, agrees that most organizations will start slowly, focusing on testing and development, onsite backups and possibly disaster recovery in the cloud. “ Most enterprises will start small, beginning with noncritical applications and then working up the stack from there,” Jones says. “The reality is that some organizations may never move human resources and other critical systems to the cloud. They’ll only use the cloud for new applications. So we definitely agree that the hybrid cloud will be a viable option for enterprises.” VMware’s Kottas says a hybrid cloud approach — in which an organization uses a public cloud for some services and runs others in a private cloud — works well with this gradual IaaS evolution. “ We think that over the next five to 10 years, the vast majority of our customers will deploy a hybrid cloud with some combination of infrastructure in an internal data center and out in the public cloud,” he says. VMware built its vCloud Hybrid Service on the foundation of its core vSphere virtualization software. With the vCloud Hybrid Service, IT departments can migrate existing virtual machines from on-premises data centers to the public cloud or spin up new virtual machines directly in the cloud. “The idea is that IT departments can write, deploy and manage applications in the cloud the same way they do today,” says Kottas. “ Using the same vSphere platform our customers run internally, they can also extend management tools into the cloud to leverage existing investments, processes and expertise.” When they work well, hybrid clouds “integrate computing, storage, security, networking, applications and management into a common, highly orchestrated onsite-offsite IT operations workspace,” notes Melanie Posey, research vice president of IDC’s IBM acquired SoftLayer in 2013, mainly to target small and midsized organizations and enterprise customers with SoftLayer’s bare metal cloud and dedicated server approach. Marc Jones, vice president of produc t innovation for SoftLayer, says his company offers two types of services: a virtual public cloud and its bare metal cloud. Many cloud providers offer a virtual public cloud, which lets the customer provision virtual machines on one of the provider’s servers. SoftLayer offers this option via the Citrix XenServer hypervisor. Jones says SoftLayer’s bare metal cloud is unique because it allows a customer to purchase a physical server in one of SoftLayer’s data centers. “ The customer can specify how much memory they want as well as the type of disk drives. We’ve found that we appeal to a lot of tech-savvy startups that start from scratch in the cloud, as well as enterprises that are replacing a service or redesigning an application,” Jones notes. Bare metal cloud offers two main benefits compared with the virtual public cloud: It is single-tenant, which means that the specific customer is the only user of the physical resources of the server; and it offers customization options to achieve consistent performance because it can easily scale as the customer organization grows.
