Data Center as a Service (DCaaS) refers to a cloud computing delivery model where a third-party provider hosts, manages, and maintains a client's data center infrastructure as a fully outsourced service. With DCaaS, the provider delivers and manages all the data center resources and services as an on-demand, elastic subscription, allowing organizations to avoid upfront capital costs and shift spending from Capex to Opex.
Components of a typical Data Center as a Service solution
A comprehensive DCaaS solution includes the management and delivery of all hardware, software, and operational requirements needed to run an on-premise data center as a fully hosted service. Key components include:
- Servers: DCaaS providers supply and manage the server infrastructure required, eliminating the need for clients to procure their own physical servers. This includes configuration, maintenance, patching, and lifecycle management.
- Storage: Storage capacity and capabilities like SAN/NAS storage, object storage and backup/DR storage are provided and maintained by the DCaaS vendor.
- Networking: Design, implementation and upkeep of the internal data center network, firewalls, load balancers and other networking equipment is handled by the service provider.
- Power & Cooling: Power generation, backup power systems, and HVAC infrastructure to regulate temperature and humidity levels within the data center are delivered and monitored as part of DCaaS.
- Security: Robust physical security measures along with implementation of firewalls, IDS/IPS systems and other cybersecurity tools and best practices are used to safeguard client infrastructure and data.
- Management Software: DCIM (Data Center Infrastructure Management) and monitoring tools are provided to give clients visibility and control over their virtual data center environment.
Benefits of Using Data Center as a Service
By outsourcing their data center operations to a
Data Center as a Service provider, organizations can reap significant benefits:
- Capital expenditure savings: DCaaS eliminates the high upfront costs of building and maintaining an on-premise data center. Clients pay only for what they use through an operational expenditure model.
- Improved scalability: The elastic nature of DCaaS makes it easy to rapidly scale resources up or down on demand to meet fluctuating computing needs. This helps avoid overprovisioning of infrastructure.
- Access to expertise: DCaaS vendors have deep technical skills and devote full-time staff to manage, optimize and support the infrastructure. This augmented expertise is difficult for most companies to replicate internally.
- Continuous innovation: Data center as a service providers continuously invest in the latest data center technologies and operational best practices to give clients access to innovative solutions without additional budget.
- Enhanced reliability: By adopting industry best practices, automated tools and deploying resources across multiple redundant sites, DCaaS enhances reliability far beyond what most in-house facilities can offer.
- Regulatory compliance: DCaaS vendors professionally manage regulatory and compliance requirements like HIPAA, PCI DSS etc. providing clients security and governance without the overhead.
- Optimized resource utilization: Centralized infrastructure shared across multiple tenants allows DCaaS providers to drive much higher efficiency compared to single company data centers through techniques like virtualization.
- Focus on core business: Outsourcing non-core data center functions to experts frees up internal resources to concentrate on strategic goals instead of infrastructure management.
Key Considerations when Adopting Data Center as a Service
While DCaaS offers clear advantages, organizations must carefully evaluate some important factors to ensure a smooth transition:
- Application compatibility: Workloads currently running on legacy or specialized systems may need refactoring to take full advantage of the standardized, virtualized DCaaS environment.
- Latency and performance: Applications with tight latency or network performance requirements must consider the physical locations of provider data centers and available connection options.
- Service level agreements: Negotiate comprehensive SLAs covering performance, security, backup/restore times etc. with financial incentives/penalties clearly defined for compliance.
- Provider viability: Thoroughly assess the financial stability and growth strategy of prospective DCaaS vendors to minimize risks from potential service disruptions.
- Customizations: Understand configurability limits within the DCaaS "as-a-service" managed model versus requirements for deep infrastructure customizations.
- Control relinquishment: Data center operations shift completely to the provider's purview under DCaaS necessitating higher levels of coordination, communication and transparency.
- Pricing flexibility: Long-term commitments with volume-based discounts or blended models may offer more predictable budgeting versus strict usage-based pricing.
The Future of Data Center as a Service is Here
As organizations continue prioritizing efficiency, large providers are rapidly expanding DCaaS footprints worldwide. Edge rollouts will boost performance for latency-sensitive workloads while hybrid models offer migration flexibility. With advantages in TCO, agility and focus, DCaaS is poised to emerge as the dominant model for delivery of on-demand, scalable data center services. By adopting the right approach, both large enterprises and SMBs stand to gain tremendously from this evolution in IT infrastructure management.
