CoreSite Features

Struggling to manage your own data center infrastructure?

CoreSite provides physical infrastructure that alleviates the burden of building and maintaining your own data centers. These are the five core CoreSite solutions that solve critical infrastructure challenges for businesses.

1. Colocation Services

Building your own data center is a nightmare.

The cost and complexity of maintaining your own IT infrastructure can drain resources. Your team gets bogged down with facility management instead of innovation.

CoreSite’s colocation services provide secure, ready-to-use physical space for your IT gear. From my testing, they handle the power, cooling, and security, letting your team focus on applications, not facilities. It’s a lifesaver for disaster recovery sites.

This means you can significantly reduce operational overhead and focus your IT staff on higher-value tasks for your business.

2. CoreSite Open Cloud Exchange® (OCX)

Connecting to multiple clouds feeling like a tangle?

Relying on the public internet for cloud connections can be slow, insecure, and create unnecessary network complexity. Managing diverse cloud links is a headache.

The OCX is CoreSite’s software-defined networking platform. What I love about this solution is how you can instantly provision private connections to any participant, including major clouds, from a single port. It simplifies your hybrid cloud strategy, offering direct, low-latency access to essential services.

You get streamlined, high-performance connectivity that enhances security and reliability across your multi-cloud environment effortlessly.

3. Cloud On-Ramps (Direct Connectivity)

Public cloud performance is often unpredictable.

Internet-based connections to public clouds lead to inconsistent performance and potential security vulnerabilities. Your critical workloads need dedicated, reliable pathways.

CoreSite facilities are major cloud hubs, offering direct physical access to AWS Direct Connect, Azure ExpressRoute, and more.

Highly customized pricing structure.

CoreSite’s pricing model is entirely quote-based, meaning you won’t find public tiers. What drives your cost includes factors like physical space (racks, cages), allocated power in kilowatts, and vital network connectivity. This custom approach ensures your pricing perfectly matches your specific IT infrastructure and redundancy requirements.

From my cost analysis, this means your budget is precisely aligned with your unique colocation needs, avoiding generic packages that overcharge you. You maintain full control over expenditure.

This value proposition empowers your business with enterprise-grade reliability and scalability.

This compares favorably to building and maintaining your own data center, freeing your team to focus on core business initiatives and optimize resources.

3. Budget Planning & Implementation

Plan your complete expenditure.

When budgeting for CoreSite, consider all factors beyond base space and power. Initial deployment, ongoing remote hands services, and varied connectivity options significantly contribute to your total cost of ownership. My cost analysis shows direct communication with their sales team is crucial to accurately forecast your long-term CoreSite pricing.

For your budget, clearly define your technical requirements upfront to ensure you receive the most accurate and beneficial custom quote tailored for you.
