CyrusOne Features

Is managing your data center infrastructure a nightmare?

CyrusOne offers a suite of integrated infrastructure services that give your business the physical foundation it needs to thrive. These are the five core CyrusOne solutions that address complex data center challenges.

1. Enterprise Colocation

Drowning in on-premise data center costs?

Building and maintaining your own data center is incredibly expensive and complex. It ties up capital and operational resources that you could use elsewhere.

Enterprise Colocation lets you rent secure space in CyrusOne’s facilities, offloading the burden of power, cooling, and physical security. From my testing, this solution offers reliable, high-uptime infrastructure without the massive CapEx. It’s ideal for hybrid cloud strategies.

You gain enterprise-grade reliability and scalability for your IT hardware without the financial drain and headaches of self-management.

2. Build-to-Suit Data Centers

Need a data center perfectly tailored to you?

Off-the-shelf data center solutions might not meet your company’s unique, large-scale infrastructure demands. Compromise can actually limit your long-term growth.

For their largest clients, CyrusOne designs and constructs entire data centers to your exact specifications, managing everything from land to layout. What impressed me most is how they optimize every detail for your specific needs, ensuring perfect alignment with your hardware.

This provides ultimate control and unmatched scalability, ensuring your facility is purpose-built to support massive and highly specialized IT operations perfectly.

3. Interconnection (CyrusOne IX)

High latency slowing your cloud connections?

Relying on the public internet for cloud or B2B data exchange can lead to poor performance and security risks. It often increases costs and reduces reliability.

CyrusOne IX creates a private, high-speed ecosystem of direct physical connections to carriers, cloud providers, and other customers. Here’s what I found: it bypasses the public internet entirely, reducing latency and improving data transfer security.

You get critical, high-performance links to public cloud resources and can establish robust, secure business-to-business data exchange efficiently.

4. Hyperscale Solutions

Can’t expand your cloud regions fast enough?

Major cloud providers face immense pressure to deploy new capacity quickly. Traditional data center builds simply take far too long to meet demand.

CyrusOne specializes in delivering massive amounts of power and space at lightning speed for the world’s largest cloud companies. This is where CyrusOne shines: they bring large data halls online in months, not years, supporting extreme power densities for AI/ML.

Hyperscalers can rapidly scale their global presence and meet soaring customer demand without being constrained by lengthy infrastructure timelines.

While optimizing large-scale infrastructure, ensuring compliance and readiness is crucial. My analysis of accreditation management software can help streamline your audit processes.

5. Remote Hands & Eyes Services

Tired of sending staff for simple reboots?

Sending your own IT staff to the data center for routine maintenance or emergencies is a huge time and cost sink. It’s an inefficient use of valuable expertise.

CyrusOne offers 24/7 on-site technicians who act as your “remote hands,” performing physical tasks like reboots, cable swaps, or equipment installs. From my evaluation, this feature saves significant operational costs and eliminates travel headaches for your team.

You eliminate the need for costly staff travel, ensuring immediate physical support for your hardware whenever you need it, day or night.

What I love about these CyrusOne solutions is how they work together to create a robust, integrated physical infrastructure foundation. This provides mission-critical support for your digital operations.

CyrusOne Pricing

What does a data center truly cost?

CyrusOne pricing is fully customized, reflecting the immense scale and tailored nature of enterprise data center solutions. For your critical infrastructure, expect a bespoke agreement, not a fixed price for your unique requirements.

1. Pricing Model & Cost Factors

Understanding their cost drivers.

CyrusOne’s pricing model bills you for three core components: physical space, reserved power capacity, and interconnection services. Power capacity often represents your largest cost since you pay for reservation, not just usage. Your final price is negotiated based on scale, contract length, and market location, not fixed tiers.

From my cost analysis, this flexible approach means your investment perfectly aligns with your specific infrastructure footprint and long-term strategy.

2. Value Assessment & ROI

True value beyond the bill.

The value of CyrusOne pricing comes from avoiding the massive capital expenditure and operational headaches of building your own data center. You gain enterprise-grade reliability and security with their >99.999% uptime SLAs. This delivers significant ROI through reduced risk and predictable operational expenses for your business.

This approach means your budget supports scalable, resilient infrastructure, allowing you to focus on core business growth, not facility management.

While securing your digital assets within a data center, understanding how to reclaim your essential information is also crucial.

3. Budget Planning & Implementation

Plan your data center budget.

Total cost of ownership extends beyond monthly fees. While direct ‘implementation costs’ aren’t separate like software, initial setup involves careful planning, solution engineering, and migration. Also, remote hands services contribute. Negotiate long-term contracts to lock in favorable rates and ensure predictable multi-year budget allocations.

Budget-wise, you need to factor in your internal IT team’s efforts for server migration and ongoing management of your hardware.

My Take: CyrusOne’s custom pricing aligns perfectly with large enterprises and hyperscalers seeking scalable, highly reliable data center infrastructure, prioritizing long-term value over upfront simplicity.

Overall, CyrusOne pricing provides bespoke, long-term infrastructure value for mission-critical operations. You need direct engagement to tailor a solution.

Alternative-wise, CoreSite excels in network-rich urban data centers, particularly on the coasts. While CyrusOne also serves the U.S., CoreSite prioritizes domestic market density.

Your situation calls for CoreSite when U.S.-centric high-performance interconnection in key domestic markets is your top priority.

Ultimately, the best CyrusOne alternatives hinge on your specific business requirements, such as geographic scope, sustainability goals, or unique scalability needs. I recommend you carefully evaluate each option based on your unique operational and growth priorities.

Setup & Implementation

Ready for a serious infrastructure overhaul?

A CyrusOne review reveals that their implementation is a major IT undertaking, not a simple software setup. This section unpacks what that means for your business, setting realistic expectations for your deployment.

1. Setup Complexity & Timeline

This isn’t a quick cloud migration.

CyrusOne implementation is a physical project, starting with detailed solution design to plan space, power, and connectivity. Your timeline depends on scale and migration complexity. Physical migration can take weeks or months, requiring secure transport of your equipment to the facility. Expect significant upfront planning.

You’ll need dedicated internal resources to manage equipment logistics and coordinate deeply with CyrusOne’s engineering teams.

What I found about deployment is that precise network design is paramount for success, ensuring seamless integration with your existing environment. This isn’t a hands-off setup.

Prepare your internal IT experts to work closely with CyrusOne on everything from power distribution to connectivity blueprints.

3. Training & Change Management

Learning curve is about processes.

Unlike typical software, there’s no UI to master. Your IT team’s learning curve involves adapting internal data center operations to an external provider’s processes and ticketing system. Implementation-wise, effective use of their ‘Smart Hands’ service depends on clear communication and understanding their support structure.

Focus on training your staff to efficiently utilize CyrusOne’s support systems and manage operations within their colocation environment.

4. Support & Success Factors

Support quality is crucial.

CyrusOne’s Remote Hands and Smart Hands services are vital, serving as your on-site team for physical tasks and troubleshooting. From my implementation analysis, the quality of this on-site support can significantly impact your operational continuity and overall satisfaction. Ensure you understand the specific SLAs for your chosen facility.

Proactively clarify support levels, response times, and the ticketing process for your facility to avoid post-deployment frustrations.

The overall CyrusOne implementation requires meticulous planning and strong internal IT expertise, delivering robust infrastructure when executed precisely. Assess your readiness thoroughly.
