Private Cloud Is Not Dead
Public cloud adoption has commanded most of the enterprise IT conversation for years. AWS, Google Cloud, and Microsoft Azure dominate headlines, and analyst reports — including RightScale’s 2017 State of the Cloud Report, which carried the subtitle “Public cloud adoption grows as private cloud wanes” — reinforce the perception that private cloud is a relic of an earlier era.
The reality on the ground, however, tells a more nuanced story. CIOs and IT professionals continue to invest in private cloud infrastructure — particularly object storage clouds — for practical reasons rooted in cost, control, and capability. Managed Service Providers (MSPs) who dismiss private cloud do so at their own commercial risk.
Here are three substantive reasons why the private cloud model remains relevant and why MSPs should treat it as a durable part of their service portfolio.
1. Public Cloud Is More Expensive Than It Appears
The primary selling point of public cloud is low upfront cost: no capital expenditure on hardware, no data center leases, and no dedicated operations staff to manage physical infrastructure. For many workloads, this calculation holds up. For data-heavy, long-lived workloads, it often does not.
Several cost factors are routinely underestimated when adopting public cloud storage:
- Egress fees: Public cloud providers typically charge for data transferred out of their network. For organizations that regularly retrieve large datasets — for analytics, compliance audits, or disaster recovery — these fees accumulate quickly and are difficult to forecast.
- Data migration costs: Moving data into a public cloud is generally free or cheap. Moving it back out, or between providers, is not. Vendor lock-in has a real cost.
- Unpredictable billing: Public cloud pricing models are complex, and monthly bills can vary significantly based on API call volumes, storage tiers, and network activity. Many organizations find cost predictability difficult to achieve.
- No room for negotiation: Public cloud pricing is largely fixed for most customers. Private cloud services delivered by MSPs, by contrast, can be scoped and priced to fit specific organizational needs.
Private object storage clouds, by comparison, can offer storage costs that are meaningfully lower on a per-gigabyte basis than standard public cloud object storage tiers, especially when factoring out egress and API charges. The hardware infrastructure cost is real, but for organizations storing and retrieving data at scale, the total cost of ownership calculation often favors the private model.
2. Object Storage Is Bringing Innovation to Private Cloud
Private cloud has historically been associated with complex, operationally demanding platforms such as OpenStack and CloudStack. These are powerful systems, but they require significant expertise to deploy and maintain, which limited their appeal to organizations with dedicated infrastructure teams.
Object storage changes that calculus. As a private cloud building block, object storage offers several practical advantages:
- Scalability: Object storage scales horizontally across commodity hardware, allowing organizations to grow capacity incrementally without expensive proprietary systems.
- Simplicity: Compared to block storage arrays or legacy NAS systems, object storage architectures are operationally simpler to manage at scale.
- Cost predictability: Because the underlying hardware is commodity-grade and the software stack is often open source (or commercially licensed at predictable rates), organizations can forecast storage costs accurately.
- Security and data sovereignty: Data stored in a private object cloud remains under the organization’s direct control, which is critical in regulated industries such as healthcare, financial services, and government.
- S3 API compatibility: Many private object storage platforms implement the Amazon S3 API, which means applications written for S3 can work against a private cloud backend with minimal modification. This preserves future flexibility for hybrid or multi-cloud architectures.
The underlying technology is mature — object storage concepts date back well over a decade — but its application to the private cloud model has accelerated as organizations look for credible alternatives to public cloud hyperscalers for specific workloads.
3. Private Cloud Creates Real Opportunities for MSPs
For MSPs, the limitations of public cloud are not just customer problems — they are commercial opportunities. Organizations that are frustrated with public cloud egress costs, compliance constraints, or opaque billing have a genuine need that MSPs are well positioned to address.
A private cloud offering built on object storage allows an MSP to deliver:
- Managed hosting with predictable costs: Customers receive a fixed-cost service agreement rather than a variable public cloud bill.
- Flexible, combined storage environments: MSPs can offer environments that combine block storage and object storage, tailored to specific application requirements, without depending on a public cloud provider.
- Personalized service and SLAs: Unlike public cloud providers, MSPs can negotiate SLAs, data placement policies, and support terms directly with customers.
- A credible path to hybrid cloud: Because many private object storage platforms are S3-compatible, customers can start with a fully private deployment and extend to a hybrid architecture later without re-architecting their applications.
The key insight for MSPs is that private cloud and public cloud are not mutually exclusive. The organizations most likely to become long-term managed services customers are those that want the flexibility and economics of cloud computing combined with the control and security of on-premises infrastructure. Private object storage is a concrete way to deliver that combination.
The Hybrid and Multi-Cloud Future Still Includes Private Infrastructure
The long-term trajectory of enterprise IT is clearly toward hybrid and multi-cloud architectures — environments where workloads are distributed across private infrastructure, public cloud services, and edge deployments based on cost, latency, compliance, and performance requirements.
In this model, private cloud does not disappear. It becomes one layer of a more complex, more capable infrastructure. MSPs and DevOps teams that understand how to design, deploy, and operate private object storage environments — and how to connect them to public cloud services through compatible APIs — will be well positioned as this architecture becomes the norm rather than the exception.
Private cloud may not generate the same press coverage as hyperscaler announcements, but for organizations with real data management, compliance, and cost challenges, it remains a serious and practical option.
