Cloud computing has revolutionized how businesses access and utilize technology resources. By moving infrastructure and applications to the cloud, companies gain scalability, flexibility, and operational efficiencies. While public cloud platforms have become ubiquitous, some organizations still have concerns about relinquishing full control of their data and operations. For these groups, a hybrid cloud model through data center as a service (DCaaS) provides an appealing alternative.
What is Data Center as a Service?
The concept behind data center as a service is pretty straightforward - instead of building and maintaining their own physical data centers, companies utilize infrastructure services from specialized providers on a pay-per-use basis. With DCaaS, businesses gain access to enterprise-grade data center resources without having to invest heavily in physical hardware, staffing, utilities, and real estate.
Providers handle all aspects of hosting, power, cooling, connectivity, security, and management through a shared, multi-tenant environment. Subscribers are able to deploy and scale their own virtual servers, storage, networking and other services on-demand via a centralized management portal or API. This delivers many of the economic and operational benefits of public cloud computing within a dedicated private infrastructure environment.
Benefits of the DCaaS Model
There are several advantages that have made DCaaS an appealing option for both large enterprises and small-to-medium sized businesses:
Capital expenditure savings - Building and maintaining an enterprise data center requires massive upfront capital outlays for land, construction, servers, networking equipment, storage, backup systems, power and cooling infrastructure, and more. DCaaS eliminates these substantial initial costs by converting infrastructure expenses to inexpensive operating costs.
Low ongoing operational costs - In addition to reducing capex, switching to an opex model with Data Center as a Service lowers ongoing costs of utilities, facility management, security, and system administration. Providers are able to achieve significant economies of scale that lower the per-unit pricing for subscribers.
Increased flexibility and scalability - With DCaaS, companies pay only for the resources they consume each month. This allows them to quickly scale up or down as business needs change without being locked into set capacity levels. Workloads and services can be dynamically provisioned on-demand.
Improved total cost of ownership - When factoring in capex avoidance, lower operating costs, and increased flexibility benefits, total cost of ownership is usually substantially lower with DCaaS compared to owning and maintaining private data centers.
Top-tier security and reliability - Data centre as a service providers make large investments in physical and logical security controls, monitoring, redundancy, and disaster recovery capabilities that would be cost-prohibitive for most organizations to achieve independently. This improves security posture and availability.
Access to advanced technologies - As a service model allows subscribers to leverage providers' large-scale investments in new technologies like hyperconverged infrastructure, software-defined networking/storage, artificial intelligence for IT operations (AIOps), and future innovations.
Elimination of procurement and maintenance headaches - DCaaS transfers responsibility for procuring, installing, and maintaining infrastructure hardware to expert providers. Customers avoid complex upgrade cycles, battery replacements, capacity planning challenges, and other administrative tasks.
Key Considerations When Evaluating DCaaS Options
While data centre as a service can streamline infrastructure management and reduce costs for many organizations, prospective customers still need to carefully evaluate potential providers. Key criteria to consider include:
- Location, availability, and latency requirements - Proximity of data centers and network architectures impacts performance and regulatory/compliance needs.
- Workload isolation and security controls - Multi-tenant infrastructure requires strict separation of customer data and preventative security measures.
- Portfolios of compute, storage, networking resources - Make sure providers can meet current and future processing and connectivity needs.
- Management capabilities and support policies - Evaluate ease-of-use, automation, SLAs, and 24/7 availability of support staff.
- Pricing transparency and flexibility - Understand all costs, growth limitations, and terms of contracts/cancellations.
- track record, stability, and financial viability - Consider reputation, expertise, size of customer base, and long-term viability.
- Regulatory compliance certifications - Examine adherence to privacy, security, and industry-specific regulations like HIPAA, PCI DSS, etc.
With an optimized data centre as a service offering, providers can deliver a compelling value proposition for managed infrastructure services. For most organizations, the benefits of scaling technical resources on demand and reducing fixed IT costs will continue to drive increasing adoption of data center as service solutions in the future.
