Managing a data center is complex, capital-intensive, and old-fashioned. Enterprises are increasingly evaluating data center exit strategies/planned decommissioning to align with IT modernization goals, reduce capital expenditure (CAPEX), and shift toward more flexible operating models.
Primary drivers catalyzing the shift are:
Cloud Migration Directive: In response to digital transformation and evolving business needs, organizations are moving their applications to the cloud. Modern workloads such as AI, machine learning, and containerized applications demand elastic compute and storage that legacy data centers cannot provide efficiently. Migrating to cloud platforms enables scalability, faster deployment cycles, and access to other advanced services.
Data Center or Colocation End-of-Lease: As colocation or data center leases expire, organizations can reassess their IT sprawl. Advances in high-density computing, shifting real estate and energy costs, and changing regional requirements often make cloud or consolidated facilities more cost-effective than renewing legacy footprints.
Hardware End of Life: Critical infrastructure, such as servers, routers, cooling systems, and power systems, has defined lifespans. Replacing these every 3–10 years demands significant reinvestment. Instead of refreshing outdated hardware, enterprises increasingly leverage this as an opportunity to modernize through cloud adoption.
Data Center Consolidation: Mergers and acquisitions often leave companies with redundant IT infrastructure. Consolidation reduces overlap, improves collaboration systems, and eliminates expensive, duplicated data center expenditures from IT budgets, directly enhancing ROI from M&A activities.
A well-structured data center exit strategy is imperative to avoid spiraling costs, disruptions, and compliance risks. It is a phased process including discovery, planning, migration, and wrap-up.
I. Discovery and Assessment
The process typically begins with a detailed discovery and assessment phase, where enterprises gain complete visibility into their current IT estate. This involves taking an inventory of existing hardware, software applications, storage systems (file shares, databases, and backups), operating systems, network configurations, and operational models, such as virtualization. Business factors are also evaluated, including active leases, penalty clauses, depreciation schedules, vendor contracts, licensing, and compliance requirements.
Once the data center footprint is captured, the next step is to map dependencies with third-party applications, domain controllers, etc., resources can then be classified and prioritized by environment type (production vs non-production), assess the business impact of applications to be migrated, pinpoint governance and business continuity requirements, and assess the enterprise’s migration readiness. To facilitate automated discovery and automated CMDB synchronization, UnitedLayer® leverages its AI/ML-driven platform, UnityOne.AI. It provides real-time observability and insights into the entire IT estate.
II. Planning and Pilot
Begin by presenting the business case to key stakeholders, then define budgets, deliverables, and timelines for migration. Design the new infrastructure architecture, landing zones, and decide the fate of data center assets upon decommissioning. Note that we support equipment disposal. Migrate workloads in phases rather than all at once, starting with simpler resources, such as file shares and databases, and then progressing to more complex ones, like applications. For application migration, begin with the most siloed applications, progressing to those with greater dependencies.
III. Migration
With discovery and planning complete, the migration phase begins. Each migration wave typically involves three stages: review, deployment, and validation/testing. Automate as many processes as possible, including provisioning, configuration management, and orchestration. Ensure logging and monitoring of both the migration processes and the workloads as they transition. Before migrating workloads, create backups and establish rollback procedures to protect against data loss or failure. Since a data center exit strategy often spans several months, ensure migrated workloads are operational alongside those still running in the legacy environment. This prevents unplanned downtime and business disruption.
UnitedLayer® also provides data center-to-data center (DC-to-DC) migration for enterprises that require relocation due to lease expirations, consolidation efforts, or regional compliance mandates. A key enabler of these services is UnityOne.AI. Its discovery module automates identification, mapping, and dependency analysis of all physical and virtual assets within your data center. This AI/ML-driven discovery provides real-time visibility and accurate metadata across servers, network devices, storage, power, and virtualization layers, eliminating blind spots and simplifying migration planning.
IV. Wrap-up (Modernize and Manage)
After all workloads have been successfully migrated and tested on the new infrastructure, it is time to shut down the old data center. This involves asset disposal, vacating the premises, and embracing the future with a modern, future-ready IT environment.
For enterprises migrating to the cloud, this stage extends into ongoing resource governance such as monitoring and optimizing resource consumption. UnityOne.AI simplifies this by offering a single-pane-of-glass view across all workloads, with real-time monitoring, consumption analytics, and AI-driven optimization recommendations to ensure the new environment remains agile, cost-effective, and future-ready.
Once workloads are migrated, the next critical step is selecting the right cloud operating model. Each approach comes with trade-offs in terms of cost, agility, compliance, and resilience, and the choice depends on the business priorities and regulatory considerations. Public Cloud is the model most often associated with “cloud computing.”
However, in this setup, all infrastructure and applications are migrated to United Private Cloud®, allowing enterprises to move away from heavy IT capital investments and embrace on-demand scalability. United Private Cloud® provides enterprises with the agility to provision and de-provision resources quickly. However, without real-time optimization, enterprises risk overspending by running idle or unnecessary instances.
Private Cloud is also emerging as the strategic equivalent to the public cloud model. With United Private Cloud®, enterprises can run traditional VM-based applications and modern containerized workloads, including AI workloads that demand high performance. It also addresses data sovereignty mandates that can lead to compliance problems.
Hybrid Cloud remains the preferred choice for large enterprises. In this model, specific applications are migrated to the cloud, while others remain in on-prem environments. This balance enables businesses to maximize ROI from existing infrastructure while retaining flexibility and ensuring that workloads remain in specific jurisdictions to meet data sovereignty mandates.
Finally, for enterprises seeking additional flexibility and redundancy, the Multicloud model provides a distributed approach.
