As the technology continues to develop and offer ever-increasing accessibility and security, more organizations are moving their data and applications to the cloud. Here we look at the three types of cloud — private, public, and hybrid — and give the lowdown on each.

Public cloud

Public clouds provide developers and consumers with easy access to computing and storage resources. With an internet connection, anybody can access a public cloud and spin up workloads quickly and easily. “The ease of use, flexibility, and simplicity are the calling cards of what makes public cloud infrastructures so popular, especially with startups and greenfield enterprise developer projects,” explains Jay Jamison, Vice President of Product Marketing for HP Helion.

A public cloud provides companies with the access to IT infrastructure and applications that they need to get their organization off the ground, and removes the need for huge up-front investment in their own IT resources. “So much capital used to get tied up in buying hardware to set up datacenters, so that startups could have robust websites,” says Jamison. “Now all you need is a credit card to get access to as many resources as you need, and you can test it as you go.”

Private cloud

A private cloud gives an organization the same accessibility to resources that a public cloud does, but also provides all of the privacies, control, and compliance requirements that a central IT organization requires.  “A private cloud enables IT organizations, and organizations that have existing enterprise infrastructures, to move to a cloud that has the efficiency of a public cloud with the security parameters needed to run a business,” explains Jamison.

Matthew Hoerig, President of the Cloud Security Alliance Canada, says: “A private cloud provides the ability to exert full control over the infrastructure and services offered. Typically, this configuration doesn’t provide a great deal of external cost savings primarily because you still require hardware, software, network and virtualization ideally in a corporate data-center.”

Managed private cloud

A managed private cloud is also a deployment model that suits some organizations. Managed private clouds provide infrastructure services without the high cost of owning and managing your own equipment or data center. This multi-tenant platform is designed and built for the enterprise, so high-end applications like SAP and Oracle can be deployed in a secure cloud environments.

Hybrid cloud

A hybrid cloud strategy — a combination of both public and private clouds — is becoming increasingly popular with larger organizations. Utilizing a large, public cloud vendor remains a great way of accessing resources, even for successful, enterprise companies who have the financial power to own a private cloud and traditional IT storage centers. “When most enterprises are for looking environments where non-production, non-security, experimental workloads can take place — that’s where public cloud vendors tend to be used,” say Jamison.

These types of enterprises also require a private cloud to provide internal developers with access to secure, controlled environments in which to build rigorous new cloud applications. “Companies tend to be early in their cloud journeys,” says Jamison. “So the promise of the hybrid cloud is to enable customers to build a cloud their way with the right leverage of their infrastructure.”
