Private Cloud: Pros

Private cloud will always be cheaper for predictable and core information technology (IT) storage and workload needs, and, for competent infrastructure professionals, it provides a more efficient total cost of ownership, according to Park.

“Interesting new offerings to support cloud-initiated IT on-premises, such as AWS Outposts, may provide private cloud with additional advantages in supporting predictable commodity IT services,” he said.

While private cloud uptime and downtime are dependent, to some extent, on the expertise of IT personnel, private cloud allows for the opportunity to build additional security, governance, continuity and recovery options above and beyond the base capabilities of public cloud facilities, according to Park.

“Although public cloud facilities have a high baseline of capability in general, they have ceilings in some of these areas based on the standardization of their cloud development or focus on specific verticals and industries to the exclusion of other specific vertical niche needs,” Park said.

Private cloud set up on-premises or close to a business also can have connectivity advantages that allow for increased ease of backup and recovery, Park noted.

“As the size of cloud data continues to increase, and network connectivity becomes a bottleneck to computing and storage access, private and hybrid cloud will be increasingly important in allowing companies to ensure continuity and compliance,” Park said. “Externally hosted private cloud still provides companies with the flexibility of direct support or defining third-party support and greater access to facilities, colocation and tools. And both externally hosted private cloud and on-prem provide greater flexibility for hardware preferences.”

Private cloud also is useful for continuity of support if organizations have trusted managed services or consultant teams that have traditionally been supporting their storage and compute or data center infrastructure management initiatives, according to Park. Private cloud allows those teams to maintain the same standards across all private cloud infrastructure, whether on-premises or externally hosted, he said.
