How to Choose the Right Hosting Model For IT?

Infrastructure decisions today are more strategic than ever. AI workloads, data localization mandates, cloud cost unpredictability, and multi-cloud expansion have reshaped how Big IT leaders evaluate their hosting architecture.

The conversation is no longer “cloud vs on-prem.” It is now about understanding which workload belongs where across four core models: Public Cloud, Private Cloud, Colocation, and Hybrid Cloud.

Enterprises increasingly prefer multi-model deployments by combining public cloud elasticity, private cloud governance, and colocation-based hardware control. ESDS, operating cloud, private cloud, and colocation infrastructure within India, fits naturally into this decision matrix.

This blog explains how to choose the right architecture using a research-driven cloud hosting comparison and an enterprise IT decision framework.

Why Hosting Architecture Matters More Than Ever

·       AI Infrastructure Is Redefining Hosting Choices

Training and inferencing workloads require high-density compute, large datasets, and low-latency connectivity. These workloads often run best on private cloud or colocation due to customization flexibility.

ESDS supports such placements through its private cloud environments and colocation racks for enterprises deploying GPU-based or hardware-optimized setups.

·       Compliance & Data Sovereignty Shape Deployment Models

With growing emphasis on local data processing, BFSI, PSU, and citizen-data workloads are increasingly placed on India-hosted private cloud or sovereign cloud zones.

ESDS cloud and data centers being located in India enable compliant workload placement for organisations requiring regulated deployments.

·       Hybrid Cloud Is Becoming the Core Enterprise Operating Model

Enterprises mix public cloud for front-end services, private cloud for core data, and colocation for specialized hardware. ESDS supports hybrid architectures where workloads run across ESDS cloud, ESDS private instances, and ESDS colocation infrastructure as part of integrated deployment models.

Understanding the Four Hosting Models

let’s explore how each model operates in real enterprise environments, and where ESDS fits.

·       Public Cloud:

Public cloud enables rapid scaling, API-driven development, and on-demand provisioning—best suited for dynamic workloads. ESDS offers a multi-tenant cloud environment hosted in India, enabling organisations to deploy applications with elasticity while meeting regional hosting requirements.

·       Private Cloud:

Private cloud gives enterprises dedicated compute resources, consistent latency, and custom security policies—important for BFSI, government, and enterprise-critical applications.

ESDS provides dedicated private cloud environments for organizations needing isolated infrastructure hosted within India.

·       Colocation:

Colocation allows enterprises to deploy their own servers while leveraging a provider’s facility infrastructure (power, cooling, network).

ESDS operates colocation data centers where enterprises can host physical machines, GPU nodes, and custom appliances—especially useful for workloads not cloud-optimized.

·       Hybrid Cloud:

Hybrid cloud blends multiple models into one operational fabric. Organizations place:

• elastic components on public cloud,
  • regulated data on private cloud,
  • high-density compute in colocation.

ESDS supports hybrid architectures where applications can operate across its cloud, private cloud, and colocation environments, allowing workload placement based on governance and performance needs.

How IT Leaders Make Architecture Choices That Scale

Modern enterprise architecture decisions revolve around five strategic questions.

1. What Are the Workload Personas?

Every workload behaves differently, and understanding its persona helps determine the ideal hosting environment. AI and ML workloads often require high-density compute and specialised hardware, making private cloud or colocation more suitable. ERP systems, SAP landscapes, and core banking platforms demand predictable performance and governance, aligning well with private cloud. Web applications and SaaS workloads typically benefit from the agility of the public cloud, while legacy systems remain better suited for colocation due to hardware dependencies. Regulated workloads require private or sovereign cloud, whereas distributed applications operate best in hybrid models. ESDS supports all these personas across its cloud and data center offerings.

2. What Level of Control Do You Require?

Control is often the defining factor in choosing a hosting model. Enterprises that require deep visibility into hardware, firmware, and custom configurations usually gravitate toward colocation, as it allows them to deploy and manage their own servers inside a professionally managed data center environment. When the requirement is for isolated virtual machines but without the overhead of maintaining physical hardware, a private cloud setup becomes more suitable. Here, organisations gain dedicated resources, consistent performance, and the ability to enforce their own security and governance policies. For teams that prioritize speed of deployment and need the flexibility to scale workloads up or down rapidly, public cloud environments offer the most practical path. Within ESDS infrastructure, all three of these models coexist, enabling organisations to match their level of control with their operational preferences while maintaining architectural continuity.

3. What Compliance Standards Apply?

Compliance requirements strongly influence workload placement, especially in sectors bound by regulatory frameworks. Industries such as BFSI, government, and healthcare often require workloads to operate in isolated environments with strict access controls, making private cloud the preferred model. Workloads involving sensitive or proprietary AI datasets may require a blend of infrastructure, private cloud for protected data processing and colocation when specialised hardware or custom GPU configurations are needed. For SaaS platforms that prioritise agility and distributed access, public cloud deployments are commonly adopted. Many enterprises with broad application landscapes ultimately settle on a hybrid approach to accommodate multiple compliance categories simultaneously. Because ESDS operates cloud and data center infrastructure within India, organisations can meet data-localisation obligations while selecting the hosting models that best align with their regulatory needs.

4. What Level of Agility Do You Need?

Agility considerations often determine how organisations architect their application layers. Teams that experiment frequently, build prototypes, or run development workloads benefit greatly from public cloud environments, where resources can be provisioned and scaled rapidly. Mission-critical systems that require stable performance and controlled change environments tend to be better suited for private cloud. When workloads depend on custom hardware, specialised AI nodes, or finely tuned configurations, colocation becomes the natural fit. Enterprises operating across multiple environments or needing seamless workload mobility often adopt a hybrid architecture, integrating public, private, and colocation resources to achieve the right balance of flexibility and control. ESDS supports these variations by enabling cross-environment operations within the same ecosystem, allowing organisations to align agility with governance and performance needs.

Security	Standard shared security	High, with isolated environments	Flexible based on design	High, driven by customer’s own
Scalability	Very high and instant	Moderate, limited by dedicated capacity	Flexible across environments	Hardware-dependent
