Beyond Public Cloud: The Enduring Case for Deployment Flexibility in eDiscovery
ComplexDiscovery Staff
In a technology market dominated by cloud-first strategies and artificial intelligence headlines, it is easy to overlook the steady, enduring demand for alternatives to public cloud eDiscovery delivery. Beneath the forecasts lies a multi-billion-dollar segment powered by organizations that cannot simply relinquish control or accept the uncertainties of multi-tenant public cloud hosting. For teams overseeing sensitive financial, healthcare, and governmental information, alternative deployment models remain prudent—a means of balancing risk management with the benefits of technological innovation. These alternatives increasingly take the form of private cloud solutions rather than traditional on-premise infrastructure, a trend suggested by both market observations and strategic investments, though precise data on private cloud’s share within this category remains limited, offering modern capabilities within controlled, dedicated environments.
Recent market shifts accentuate the complexity facing decision-makers. Relativity’s January 2025 announcement that new matters created on or after January 1, 2028, must be hosted in RelativityOne pushes many institutions to weigh cloud flexibility against entrenched regulatory and operational needs. Meanwhile, the October 2025 strategic partnership between Reveal and Consilio introduces Reveal Private Deployment within Consilio’s Aurora platform, blending powerful analytics with tailored infrastructure to address risk-averse enterprises. These strategic moves represent more than market positioning—they illuminate a crossroads between innovation and compliance, where the challenges of migrating sensitive data become as important as the opportunities they present.
Understanding Deployment Models
Navigating this landscape requires careful differentiation between deployment models. While discussions often simplify to “cloud versus on-premise,” the reality involves nuanced distinctions that significantly impact organizational control, compliance capabilities, and operational flexibility.
Public Cloud: These solutions operate in multi-tenant environments where multiple organizations share infrastructure managed by third-party vendors like Microsoft Azure or AWS. Platforms such as RelativityOne exemplify this model, offering unmatched scalability and rapid innovation—qualities that are attractive to organizations seeking lower upfront costs and advanced analytics capabilities. Yet for institutions in regulated spaces, concerns mount regarding data sovereignty, regulatory mandates, and cost predictability, especially when stakes are high.
Private Cloud: Sometimes called a dedicated or hosted deployment, this approach delivers cloud benefits—such as elastic scalability and modern infrastructure—within isolated, single-tenant environments. Critically, private cloud solutions are still hosted and managed by service providers rather than the client organization itself. Examples include Relativity Server when hosted by providers like HaystackID in their secure data centers, or Consilio’s Aurora platform built on Consilio’s private cloud infrastructure. (Note: Relativity Server can also be deployed as true on-premise within client-owned data centers, making it one of the few platforms that spans both categories depending on deployment choice.) This model typically provides greater data control than public cloud, enhanced compliance capabilities, and customized configurations, while avoiding the capital expenditure and operational burden of true on-premise infrastructure. Many healthcare, government, and financial firms view private cloud as an ideal middle ground: leveraging technological advances without sacrificing legal or operational certainty.
On-Premise: This is the most traditional deployment model, where organizations maintain direct, physical control over infrastructure and data in their own data centers. With servers and storage kept behind organizational firewalls and managed by internal IT teams, on-premise deployment enables the strictest chain-of-custody, evidence integrity, and compliance with specialized IT or legal policies. However, this approach requires significant capital investment, dedicated IT staff, and foregoes the cloud’s elastic scalability. True on-premise deployments are increasingly rare as organizations migrate to private or public cloud alternatives that reduce operational complexity.
The distinction between private cloud and on-premise is crucial: private cloud involves third-party hosting in dedicated environments, while on-premise means the organization owns and operates its own infrastructure. Market data often combines these categories under “on-premise” or “off-premise” classifications, potentially obscuring the growing role of private cloud as a bridge between traditional on-premise control and public cloud innovation.
Market Growth and Investment Trends
Against this backdrop, growth in eDiscovery spending tells a revealing story. According to ComplexDiscovery’s 2024-2029 Market Size Mashup, global eDiscovery software spending is projected to climb from $6.08 billion in 2024 to $9.54 billion by 2029—a compound annual growth rate of approximately 9.4%. (While these figures reflect one influential forecast model, other research firms such as Grand View Research project similar growth trajectories with differing market valuations, reinforcing the broader trend without presuming exact convergence.) When services are included, the total market is expected to reach $25.11 billion by 2029.
Notably, what market analysts typically classify as “on-premise” solutions—a category that encompasses both true on-premise infrastructure and private cloud deployments—are decreasing in market share from 27% to 22%, yet actually rise in absolute terms, moving from $1.64 billion to $2.10 billion over the five-year period. (It is worth noting that market terminology may vary, and some industry models—such as the one used by ComplexDiscovery—define “on-premise” broadly to include both self-managed infrastructure and provider-managed, dedicated environments. As such, interpreting trends within this category requires attention to deployment definitions.) This sustained growth in absolute dollars reflects continued investment by critical verticals—including government, finance, and healthcare—driven by regulations, security concerns, and the need for customized business controls. The decline in relative market share indicates not abandonment but rather that cloud-based alternatives are growing even faster.
Competitive Dynamics and Strategic Partnerships
Competitive dynamics remain intense in regulated sectors, with specialists building reputations on security, infrastructure control options, and keeping clients protected from the headline risks that public cloud breaches can bring. The Consilio-Reveal partnership exemplifies the industry’s movement toward private cloud as a viable middle path, as Consilio CEO Andy Macdonald noted: “With Relativity choosing to disallow new matters in Server starting in 2028, we saw a clear need to support clients who are looking for more control over their costs than what traditional public-cloud models offer.”
The partnership integrates Reveal Private Deployment within Consilio’s Aurora platform, which operates on Consilio’s private cloud infrastructure. This approach provides organizations with deployment flexibility—neither pure public cloud nor traditional on-premise—but rather dedicated, single-tenant environments that balance control with modern cloud capabilities.
Successful migrations from legacy infrastructure involve not only technical prowess but strategic, patient engagement with metadata management, defensibility requirements, and business continuity at the forefront. The most innovative organizations now employ hybrid approaches that leverage different deployment models based on data sensitivity: public cloud platforms like RelativityOne for matters requiring maximum scalability and latest AI features, private cloud solutions for sensitive matters demanding enhanced control, and in rare cases, true on-premise infrastructure for the most stringently regulated workflows, although navigating this flexibility is not without complexity. Migrating to private cloud often requires careful planning around cost structures, internal change management, and integration with legacy systems—factors that must be weighed alongside regulatory and operational goals.
Looking Forward
Ultimately, offering alternatives to public cloud deployment remains not just rational but strategic, especially for providers facing years of persistent demand amid the evolving digital transformation of legal workflows. With market figures pointing toward nearly $10 billion in annual software spend and continued growth in the absolute value of controlled-deployment solutions—whether true on-premise or private cloud—providers that differentiate clearly and respond quickly to customer regulatory needs will continue to thrive.
The future likely belongs not to any single deployment model but to platforms that offer genuine flexibility, though this direction is based on current market dynamics and may evolve as regulatory, technological, and economic conditions shift. Organizations increasingly demand the ability to choose where their data resides based on specific requirements: public cloud for routine matters that benefit from rapid innovation, private cloud for sensitive matters that require enhanced control, and on-premises infrastructure only when regulatory mandates or institutional policies absolutely require it. The market’s evolution suggests that private cloud solutions—combining modern capabilities with organizational control—represent the growth frontier for providers serving risk-conscious enterprises.
Deployment model diversity in eDiscovery is no longer about defending legacy infrastructure—it’s about meeting diverse organizational needs with appropriate solutions. The market data confirms what practitioners already know: organizations will continue investing in alternatives to public cloud, not out of technological conservatism, but out of operational necessity. Providers who understand this distinction and deliver proven solutions across deployment models will define the industry’s next chapter. Equally important is recognizing that deployment strategy is not one-size-fits-all. Public cloud remains a strong fit for many scenarios where scalability and innovation outweigh control concerns, while some organizations still require or prefer on-premises infrastructure for specific use cases. The strength lies in matching the model to the mission.
As organizations weigh deployment options, it’s worth remembering that today’s convenience can become tomorrow’s constraint. A reasoned, forward-looking choice—one grounded in operational realities and regulatory foresight—can prevent infrastructure from becoming an unintended barrier to future innovation, compliance, or cost control.
Postscript: First Principles Matter
Amid discussions of deployment models, market forecasts, and strategic partnerships, it bears emphasizing what should be a blinding flash of the obvious: solutions must actually work and be demonstrably proven to work before any deployment option becomes beneficial.
The question is not simply whether to choose public cloud, private cloud, or on-premise infrastructure. The fundamental question is whether the eDiscovery solution—regardless of where it lives—can reliably accomplish what organizations need it to do: process data accurately, maintain chain of custody, support defensible workflows, scale appropriately, and integrate with existing legal and compliance processes.
A cloud-based solution that fails to meet accuracy standards or raises defensibility concerns is no better than an on-premises system that cannot handle the required data volumes. Conversely, a proven on-premise platform that delivers consistent results may be vastly superior to an untested cloud offering with impressive marketing materials.
Organizations evaluating deployment options should therefore establish a hierarchy of concerns. First, does the solution work as required, and can it be validated and proven in your specific use case? Second, does it meet your compliance and security requirements in ways that can be audited and certified? Third, can it scale and integrate with your workflows in a way that aligns with your operational reality? Only after answering these questions does the choice of deployment model become meaningful.
The infrastructure debate—public, private, or on-premise—becomes relevant only after establishing that the underlying solution is sound, tested, and fit for purpose. This is not merely common sense; it is the foundation upon which billions of dollars in eDiscovery investments must rest. No amount of cloud innovation or on-premise control can compensate for a solution that simply does not work when it matters most.
