Magic Quadrant for Data Center Outsourcing Services

Data Center Outsourcing Services Vendor Product Comparisons 2025

Key features and pros and cons of top Data Center Outsourcing Services products:

Accenture - Leader

Pros:

Business-Outcomes Focus: Accenture uses outcome-based contracts to closely align its services with client business objectives by stitching together fees and measurable business outcomes, rather than just deliverables. This approach reflects Accenture's commitment to shared risk, strategic partnership, and strong client relationships. Accenture's value-realization tracking and 360° Value Meter go beyond traditional SLA metrics by providing a holistic view of business outcomes across financial, experience, talent, inclusion and diversity, sustainability, and client priorities.
Midsize Enterprise (MSE) Expansion and Strong Industry Expertise: Accenture uses its consulting-led approach and deep industry knowledge to provide tailored solutions and address complex requirements for industries like finance, healthcare, and manufacturing. The company is strategically expanding its services for MSEs by using key acquisitions like Navisite to deliver specialized offerings.
Proprietary AI and Tooling: Accenture is advancing data center outsourcing by developing proprietary AI platforms, like GenWizard, which automate workflows and improve incident resolution. In addition, tools such as myNav and Cloud Network Operator enhance cloud migration and unified management.

Cons:

High Customization Premium: Accenture's tailored, transformation-led approach can increase costs compared to standardized offerings. Organizations seeking cost reduction without broader transformation may not make the most of Accenture's capabilities, despite the premium to acquire them.
Vendor Lock-In: Heavy reliance on Accenture's proprietary platforms, methodologies, and ecosystem partnerships can increase organizational dependency, limiting flexibility and raising switching costs. This may make it challenging to quickly adopt new technologies or transition to alternative providers. Clients should carefully consider the potential vendor lock-in and ensure their long-term technology strategy maintains adaptability and independence to avoid future operational or strategic constraints.
APAC Revenue Declined: Despite strong overall revenue growth, Gartner estimates that Accenture's APAC revenue declined roughly 6%, and it maintains a limited presence in the region — APAC contributes only 7% of its overall DCO services revenue. Clients in APAC should carefully consider this and evaluate Accenture's strategies for strengthening its regional business.

HCLTech - Leader

Pros:

Midrange Systems Support: HCLTech delivers project and managed services across more diverse midrange platforms than all over vendors in this Magic Quadrant. HCLTech appeals to customers relying on IBM i, IBM AIX, HP-UX, Oracle Solaris, VSI OpenVMS, Tru64 UNIX, or Tandem NonStop for their mission-critical workloads. Organizations with mission-critical legacy workloads can benefit from HCLTech's technical expertise, comprehensive platform support, and experience in maintaining, modernizing, and ensuring continuity for complex IT environments.
Deep Vertical Industry Expertise: HCLTech demonstrates strong industry expertise with tailored solutions like IFRS, AI-powered VisionX for logistics, CARE for healthcare, and BluGenie for telecom. These offerings accelerate deployment, enhance productivity and safety, reduce costs, and deliver faster time to value and measurable business outcomes.
Driving Efficiencies Thorough Predictive Analytics: HCLTech emphasizes automation with its VisionX platform, integrating AI-driven insights and predictive analytics to enhance efficiency and reduce operational downtime. This intelligent suite enables proactive incident management, automated root cause analysis, and continuous process improvement.

Cons:

Service Quality Concerns: Some HCLTech clients report concerns about service quality, citing challenges like resources being stretched across multiple projects and difficulties in retaining experienced team members. Clients should actively monitor service quality, clarify resource commitments, and establish clear escalation processes to promptly resolve any gaps.
Primary Focus on Large Deals: Although HCLTech claims to focus on MSEs, its approach is limited. It primarily focuses on large clients, who receive the majority of its resources and strategic attention. MSE clients should carefully evaluate HCLTech's actual capabilities, delivery models, and willingness to prioritize their specific needs before selecting it as a preferred vendor.
High Reliance on Subcontractors: HCLTech's high use of subcontractors for its DCO delivery introduces potential risks around service consistency, control, and quality. It may also impact security, especially for sensitive workloads. Organizations with strict quality or compliance requirements should clearly define subcontractor roles and oversight before engagement.

Kyndryl - Leader

Pros:

Embedded Consulting Approach: Rather than building a separate consulting business, Kyndryl integrates advisory capabilities via Kyndryl Consult with managed services and partner technologies. This integrated approach enables it to deliver outcome-based IT engagements aligned with client IT objectives.
Focus on IBM Mainframe and Midrange: Kyndryl offers a comprehensive portfolio of IBM Z and IBM Power services under its Core Enterprise and zCloud Services umbrella, managing over 6.1 million MIPS, 25 million CPW, and more than 7,000 mainframe practitioners. With broad investments and a robust service offering, Kyndryl is well-positioned to support customers seeking a provider to manage and evolve their mainframe and midrange platforms.
Real-Time AI-Powered Platform: Kyndryl is actively investing in Kyndryl Bridge, an AI-powered platform that delivers clients real-time visibility into their IT environments. Unlike competitors who primarily market automation with limited uptake, Kyndryl integrates Bridge directly into its managed services to enable unified IT management. This approach enhances transparency and operational efficiency while also driving continuous innovation through advanced automation and actionable, data-driven insights.

Cons:

Legacy Challenges Persist: Kyndryl, formed from IBM's divestiture, retains certain inherited rigidities like low-margin legacy contracts, complex operational processes, and reliance on legacy infrastructure. Despite ongoing improvements, Gartner clients express concerns about limited resource availability, high costs and complex pricing structures, and, in some instances, a lack of proactive service delivery. Clients should thoroughly evaluate these factors before deal execution.
Limited Focus on Business Outcomes: Kyndryl continues to lead its engagements using technology-centric approaches rather than focusing on business outcomes, which may not resonate with clients who prioritize business results over technological solutions. Clients should thoroughly review Kyndryl's roadmap to understand how they can maximize value from the engagement.
C4i and Skytap Integration: Kyndryl's plan to integrate Skytap with its established C4i offering is still in progress. Gartner clients report confusion about which solution to select, given significant feature overlap between the two.

Consulting-Led Growth: Wipro actively collaborates with hyperscalers, OEMs, and startups through joint go-to-market initiatives, COEs, and partner funding to expand market reach. Its consulting-led approach, strong sales performance, and emphasis on growing large accounts position Wipro as a trusted advisor and growth provider.

Cons:

Leadership Changes and Strategic Uncertainty: Wipro's leadership changes and strategic realignments may impact its operating model and project direction. Existing clients should engage with Wipro to understand possible impacts on its ongoing roadmap and clarify how these changes could affect current and future initiatives.
Rising Staff Turnover: Over recent years, Wipro's attrition rates exceeded 15%, which may impact service continuity and increase training costs. Persistent talent shortages — especially for specialized skills in cloud, cybersecurity, AI, and mainframe — pose ongoing challenges that could affect client confidence in delivery stability for long-term outsourcing engagements.
Price Competitiveness: Wipro's DCO business is experiencing cost pressure and diminishing margins. Intense, competitive bidding and higher pricing compared to competitors has led to lost deals, making Wipro less attractive to cost-focused clients.

Atos - Challenger

Pros:

AI-Driven Innovation and Automation: Atos adopts an 'AI/GenAI/agentic AI-first' strategy across all services, including developing its digital engineer automation platform. This enables transformative experiences, predictive maintenance, and fully autonomous managed service delivery, and positions Atos at the forefront of intelligent IT operations and modernization.
Comprehensive Service Coverage and Integration: Atos offers a full spectrum of IT infrastructure services, from legacy on-premises to hybrid cloud, edge and network environments, all managed and orchestrated from a single source. Atos focuses on sovereign cloud services, AI, and connecting mainframes to cloud regions for faster performance. Its proprietary Atos Bridge platform enables deep integration, AI-driven visibility, and predictive analytics to align IT operations with business outcomes.
Focus on Security: Security is a core focus of Atos, reinforced by zero trust architectures and compliance with evolving regulations like NIS2 and DORA. Atos infuses cybersecurity within each of its managed services offerings, rather than treating it as an external capability.

Cons:

Financial Instability and Restructuring: Atos encountered significant financial challenges, like declining revenue, high debt, and multiple profit warnings. To stabilize its financial position, the company embarked on major restructuring initiatives, including proposed sales of certain business units and new leadership. While these actions and the upgraded credit rating may ease concerns, clients should still conduct due diligence.
Leadership Changes and Evolving Strategy: Frequent changes in senior leadership and board members contributed to strategic instability, making it difficult for Atos to consistently execute long-term plans. Clients engaging with Atos should understand the roadmap and the possible impact the changes may have, along with their short-term and long-term implications on the client's current strategy.
Service Quality Concern: Some Gartner clients have expressed concerns regarding Atos' service quality, highlighting inconsistent project delivery, delays in transformation initiatives, and a shortage of skilled resources, and it holds a below-average Peer Insights score. Clients are encouraged to thoroughly assess Atos' service quality assurances before entering into any engagement.

Cognizant - Challenger

Pros:

Emphasis on Industry-Specific Solutions: Cognizant delivers tailored IT infrastructure solutions through over 120 industry-specific, plug-and-play cloud offerings, such as Stores 360 for retail and TriZetto for healthcare. Its vertical go-to-market strategy and strong industry partnerships enable sector-specific solutions with strict data security.

Cons:

Evolving Enterprise Systems Offering: Cognizant's IBM mainframe support is evolving to match market shifts from mainframe exit strategies to treating the mainframe as a strategic platform. As the transition to MFaaS and modern mainframe is still in progress, customers should scrutinize if Cognizant already has the necessary capabilities to support their mainframe estate.
Limited Geographical Capabilities: Cognizant still depends on the North American (NA) market, with Gartner estimating that over 70% of its DCO business originates from this region. Cognizant hasn't diversified enough in other markets, making it more vulnerable to U.S. policy shifts in today's uncertain environment. Clients outside NA should carefully examine Cognizant's footprint in the specific locations they need on-site presence.
Limited Focus on MSE Clients: Cognizant's focus remains primarily on large enterprises, with only 3% of its client base coming from the midsize enterprise (MSE) segment. Clients in this category should closely evaluate Cognizant's interest and capability to support their unique requirements before engaging.

Cons:

Revenue Challenges: DXC faces consistent revenue declines in recent quarters and years, indicating challenges in maintaining and expanding its client base in a competitive market. This may limit its investments capabilities, so clients engaging with DXC should get clarity on its roadmap that includes impacts from its fiscal situation.
Challenges With Transformation: As DXC transforms its business model to focus on higher-growth areas, it may face internal challenges in retraining its workforce, developing new capabilities, and integrating new solutions with existing IT infrastructure. Existing clients should engage with DXC to understand any change in the roadmap and potential implications.
Competitive Pricing: DXC has lost deals due to lack of competitive pricing, indicating challenges in highly price-sensitive markets. Gartner client feedback also highlights difficulty getting value for the money spent, so organizations seeking cost-competitive deals may find DXC's services comparatively costly.

Fujitsu - Challenger

Pros:

Strong Industry Solutions: Fujitsu excels in the public sector through strong governance and a customer-centric approach, prioritizing security and compliance.

By delivering scalable infrastructure, flexible pricing, dedicated support, and built-in security, Fujitsu effectively meets their requirements for modernization, agility, and compliance, positioning itself as a strong partner in this market segment.
Strong Sustainability Commitment: Fujitsu's Uvance strategy prioritizes sustainability across its global hybrid IT and DCO services. The company emphasizes energy efficiency, climate-neutral operations, and advanced carbon management, delivering green data centers aligned to market trends and customer expectations. Data centers use renewable energy and offer secure, sustainable operations with transparent energy usage reporting.

Cons:

Relatively Low Consulting Maturity: Uvance Wayfinders is Fujitsu's new global consulting business focused on technology-driven differentiation. Given its recent establishment in April 2025, clients should carefully assess Fujitsu's global consulting capabilities versus their DCO needs and the outcome-based goals Fujitsu will contractually commit to.
Evolving Business Model: Fujitsu's global DCO services revenue declined by 12%, which the company attributes to an intentional shift in business strategy and portfolio mix toward consulting services, high-margin offerings, and cloud services. As part of this transition, Fujitsu reassessed its deals and closed several data centers in Europe, resulting in fewer managed facilities. Clients should review their own strategies and consider how Fujitsu's shift may affect them.
Cultural Influence on Operations: Fujitsu's operations outside Japan continue to benefit from the influence of Japanese business practices, which can offer some unique strengths in global markets. However, CIOs should proactively consider how these approaches to customer account management, service delivery, and the globalization of the operating model are adapting to meet the distinct needs of Western markets, ensuring ongoing relevance and success.

Infosys - Challenger

Pros:

AI-Enabled Industry-Focused Solutions: Infosys distinguishes itself through its focus on industry-specific solutions tailored to sectors' unique needs. Its Finacle core banking suite, healthcare solution, and Infosys Equinox (a retail-centric offering) are prime examples.

Flexible Service Delivery: Infosys supports clients with a broad range of customization options, from standardized global offerings to fully custom solutions tailored for a single client, with a healthy distribution for these models across its client base. Its range of commercial models, including consumption-based, outcome-based, and OPEX savings models, also reflect this flexibility.

Cons:

Limited Mainframe Capabilities: Infosys' asset-light DC model depends on third-party partners rather than owned infrastructure, with limited in-house mainframe capabilities. Its mainframe services are usually part of broader IT deals and rely on external expertise, which may reduce direct control and consistency compared to providers with stronger in-house infrastructure. Clients should consider this when evaluating mainframe-led engagements with Infosys.
Large Enterprise Focus: Infosys's DCO strategy focuses on large deals and clients, supported by dedicated deal advisors and analysts. MSE organizations should assess whether Infosys will be a good fit for their scope and size requirements.
Improvement Delivery Challenges: Gartner client feedback indicates that Infosys is less proactive in offering process improvements and leveraging best practices from other projects. Clients report challenges in securing expertise and resource allocation. Organizations seeking continuous improvement and effective resource management should review Infosys' contractual commitments and delivery capabilities.

Cons:

Fragmented Global Operations: Clients with global operations have occasionally encountered challenges in achieving seamless support across onshore locations. Additionally, the layered nature of internal collaboration may introduce cost and delivery considerations that are not always immediately visible. Clients are advised to evaluate these structural interdependencies to ensure alignment with their delivery expectations.
Limited Mainframe and Midrange Focus: Capgemini makes limited investments in IBM Z mainframes, usually within larger outsourcing or application engagements, and does not prioritize other mainframe or midrange systems. It mainly focuses its mainframe activities on application support or facilitating mainframe-exit initiatives.
Service Quality Concerns: Gartner clients raised concerns regarding Capgemini's knowledge transfer, operational stability, and integration, citing key issues in rigid resource onboarding and offboarding processes. Clients working with Capgemini should develop a clear roadmap for customer satisfaction and governance to address any gaps.

Cons:

Limited Mainframe Hosting: Deloitte primarily offers its mainframe services during mainframe exit projects, rather than options for long-term modernization or ongoing value. Organizations with large mainframe estates seeking a strategic provider for in-platform transformation should review their capabilities, as Deloitte's capabilities in this area are very limited.
Premium Pricing: Deloitte positions its DCO offering as a premium, high-value service, which may result in higher costs compared to competitors focused on commoditized or cost-optimized solutions. This premium approach may not align with organizations primarily seeking cost-efficiency.
Limited Owned Infrastructure: Deloitte doesn't own many data centers. This results in a heavier reliance on client-owned and third-party (colocated) data centers, which limits Deloitte's direct control over infrastructure, potentially impacting responsiveness and agility in scenarios where direct ownership is a key client requirement or differentiator.

NTT DATA - Visionary

Pros:

Flexible and Wide Private Cloud Offerings: NTT DATA provides a wide range of private cloud offerings tailored to client needs, including dedicated, multitenant, on-premises, colocation, and data center options. Clients seeking vendors with robust on-premises solutions and seamless hybrid cloud integration — focused on transitioning from legacy systems to modern, containerized, and AI-ready infrastructures — are an excellent fit for NTT DATA's capabilities.
Operational Excellence and Innovation: NTT DATA leverages automation and AIOps to deliver significant operational efficiencies. Its structured approach to cloud migration and modernization, investment in private AI (GPU-aaS) and alternatives to VMware demonstrate a commitment to continuous improvement and technological advancement.
Sustainability and Compliance Focus: NTT DATA deeply integrates sustainability into its strategy and service portfolio, including sustainable IT, applications, cloud, and data centers. It offers client-specific emissions reporting, energy-efficient facility designs, and alignment with global standards (like ISO 14001 and ESG frameworks) to help clients meet regulatory and board-level sustainability goals.

Cons:

Inconsistent Transition Quality: As NTT DATA continues to transform its regional operating model to a global operating model, clients may experience inconsistent service quality, maturity, and responsiveness, depending on their region and stage of transformation. Clients should establish clear SLAs, conduct regular performance reviews, maintain open communication with both regional and global teams, and closely monitor the progress of the transition.
Pricing Flexibility Gaps: Clients indicate that NTT DATA's pricing is often higher than anticipated, with additional fees and less contractual flexibility relative to competitors. Limited cost transparency has led to client dissatisfaction and, in some instances, contract attrition.
Limited Mainframe Focus: NTT DATA's mainframe services are a specialized part of its portfolio, rather than a primary revenue driver. While NTT DATA offers structured transition and transformation solutions to help clients migrate from legacy mainframe systems to modern, containerized, hybrid, and AI-ready environments, organizations with significant mainframe needs should carefully evaluate the company's investment and expertise in this area.

Ensono - Niche Player

Cons:

Limited Execution Beyond Mainframe Portfolio: Ensono excels in mainframe and mainframe modernization services; however, its offerings in areas such as ERP and data center (DC) modernization represent a smaller portion of the company's overall revenue, with only 8% of deals focused on transformation. Clients seeking services beyond mainframe should conduct thorough due diligence to ensure Ensono's offerings align with their long-term investment and support needs.
Limited Non-IBM Mainframe Support: Ensono's expertise centers on IBM Z mainframe and IBM Power systems, providing strong services and modernization support for these platforms. However, organizations utilizing other mainframes like Fujitsu, Unisys, NEC, or various enterprise UNIX systems may encounter limited support from Ensono. These clients should consider alternative providers with broader capabilities across diverse mainframe and midrange environments.
North America Focus: Ensono's business currently skews toward North America, which accounts for approximately 90% of its overall DCO services revenue. Europe contributes around 10%, while its presence in APAC generates just 1% of revenue. Clients with a global footprint should carefully assess Ensono's capabilities and resources to ensure their needs can be effectively supported outside the U.S..

LTIMindtree - Niche Player

Pros:

Integrated Service Portfolio: Since merging LTI and Mindtree in 2022, LTIMindtree has integrated its strengths to offer a broader, more versatile service portfolio. It expanded managed services, advanced AI-driven innovation, and launched proprietary platforms like CloudXperienz and LTIMindtree AIOps platform, resulting in greater operational efficiency, revenue growth, and improved client satisfaction.
Private Cloud Strength: LTIMindtree excels in private cloud services, which generate nearly 60% of DCO revenue. Its end-to-end solutions enable workload optimization, orchestration, disaster recovery, and cost management. This empowers organizations with full control, security, and operational excellence.
Strong Client Relationships and Deal Momentum: Gartner client feedback highlights LTIMindtree's consistently high customer satisfaction, with clients noting the company's flexibility in handling project scope changes, effective collaboration with partners, and prompt responsiveness to their needs. This strong client focus is reflected in LTIMindtree's business performance, with total DCO services revenue increasing by 17% and the addition of 40 net new DCO clients during the assessment period, and a robust deal pipeline supporting continued growth.

Cons:

Limited Platform Specialization: LTIMindtree demonstrates limited mainframe capabilities and does not prioritize mainframe or midrange systems within its core strategy. These platforms are generally managed only as components of broader outsourcing engagements, rather than as dedicated focus areas. Organizations seeking specialized expertise in mainframe or midrange environments may find LTIMindtree's approach less tailored to these requirements.
Lagging Automation Maturity: LTIMindtree's overall automation maturity lags behind its peers. Its automation approach relies predominantly on open-source and partner tools, with limited evidence of advanced proprietary automation platforms or tools. Clients should thoroughly evaluate LTIMindtree's automation capabilities, particularly when automation is critical to the engagement.
North America Focus: LTIMindtree originates roughly 70% of its DCO revenue and 68% of its clients from NA. However, most of its DCO services staff are based in APAC, while only 4% of its clients are in that region. Clients seeking onshore or nearshore support should carefully assess LTIMindtree's regional resource allocation and staffing models.

Tech Mahindra - Niche Player

Pros:

Focus on Industry Solutions: Tech Mahindra's DCO services strategy emphasizes industry-specific solutions through pre-engineered templates tailored for sectors like telecom, manufacturing, healthcare, and BFSI. These blueprints enable Tech Mahindra to address unique regulatory, operational, and compliance requirements, accelerating deployment timelines and reducing risks linked to sector-specific challenges.
Digital Twin Integration: Tech Mahindra employs digital twin technology in its data center outsourcing operations to create virtual models of physical infrastructure. These digital twins enable real-time performance benchmarking, predictive maintenance, and scenario testing before changes are implemented in production environments. Tech Mahindra's integration of this technology is progressive among the competition.
Strategic Partnerships: Tech Mahindra focuses on its strong alliance network of over 40 partners, including leading hyperscalers, OEMs, and ISVs. These collaborations drive co-innovation and joint solution development, granting early access to emerging technologies like AI-powered infrastructure. Tech Mahindra stands out with its agentic AI platform, TENO built with NVIDIA, Ops amplifAIer for AI-powered IT operations, TechM VerifAI for safe and ethical AI use, a dedicated IBM Cloud Practice, and Hybrid BlazeTech for smooth private and multiplatform management.

Cons:

Siloed Team Structure: Tech Mahindra's DCO services use dedicated teams for specialized client support in each major vertical — telecom, BFSI, healthcare/life sciences, and manufacturing. However, this siloed structure can cause duplicate effort, inconsistent practices, and limited cross-industry learning, as each vertical has separate leadership and teams.
Low Client Retention Rate: Tech Mahindra's client retention rate stands at 73%, significantly lower than the 85% to 99% typical of its key competitors. This lower retention rate may indicate challenges in maintaining long-term client relationships, something organizations should carefully review before finalizing any long-term deals.
Limited Transformation Engagements: Eighty-two percent of Tech Mahindra's deals are cost-led, and only 18% are transformation-led. This indicates that most of its client engagements focus on operational efficiency and cost, rather than large-scale digital transformation. Organizations seeking a provider for transformation-led initiatives may find Tech Mahindra's experience and focus in this area limited.

Unisys - Niche Player

Pros:

Security and Compliance Focus: Unisys offers strong expertise in operating secure and compliant data center environments, particularly for clients in highly regulated sectors like government and finance. Its cybersecurity approach spans from strategic advisory and compliance to real-time threat detection and remediation. With a strong emphasis on resilience, Unisys is enhancing its portfolio with zero trust architectures and advanced recovery solutions.
Unisys Mainframe Experts: Unisys is a leading provider of project and managed services for its ClearPath mainframe systems, managing over 1 million MIPS — 96% of its total MIPS across Libra and Dorado systems. Clients operating on OS2200 or MCP environments benefit from Unisys' comprehensive support, which includes infrastructure and application management, as well as robust modernization capabilities.
Emphasis on Automation: Unisys differentiates itself using its Intelligent Operations methodology powered by AI-led, unified service management solutions and services. This enables centralized control, predictive uptime, real-time monitoring, and automated service delivery across diverse environments. The approach reduces manual interventions, improves incident resolution times, and enhances reliability to support clients' digital transformation and operational efficiency goals.

Cons:

Lack of Support for IBM Enterprise Systems: Unisys does not own IBM mainframes for its clients and provides only limited support, with just 4% of its total MIPS attributed to IBM systems. Unisys relies on partners for broader IBM mainframe or midrange needs, so organizations seeking support for these platforms should carefully assess Unisys' capabilities.
Organizational Restructuring: Unisys recently underwent a reorganization and leadership changes that may influence its future roadmap and strategy. Clients must engage with Unisys to evaluate potential impacts on operational stability, service evolution, staffing requirements, transition, and outcomes to ensure sustained alignment with Unisys' advancing capabilities and strategic objectives.
Limited Outcome-Based Engagements: Unisys reports only 5% of its DCO deals as outcome-based compared to its peers. Organizations should carefully evaluate Unisys' approach, as outcome-based agreements are critical for managing risk, cost, service quality, and compliance — especially when clients require contractual alignment to measurable business outcomes and tangible value.
