A shared private cloud is a cost-effective alternative to a dedicated private cloud, offering private cloud benefits at a lower price point.
Understanding Shared Private Cloud
Instead of owning and maintaining the entire hardware infrastructure yourself, a shared private cloud allows multiple users to share the underlying hardware while still maintaining the security and privacy of a private cloud environment. Think of it as a private room (your cloud environment) within a shared building (the hardware infrastructure).
Key Characteristics
-
Cost Efficiency: As highlighted in our reference, "the shared private cloud is a more cost-efficient alternative to the dedicated private cloud." You don't bear the full cost of the hardware.
-
Resource Sharing: Multiple tenants share the underlying hardware infrastructure. This can include servers, storage, and networking equipment.
-
Private Environment: Despite sharing infrastructure, each tenant has a logically isolated and secure environment. This isolation is typically achieved through virtualization and other security measures.
-
Control and Customization: While the hardware is shared, you often retain a significant degree of control over your virtualized environment, including the ability to customize your operating systems, applications, and security policies.
Benefits of a Shared Private Cloud
- Reduced Costs: Lower capital expenditure (CAPEX) and operational expenditure (OPEX) compared to dedicated private clouds. This is often a significant driver for organizations.
- Scalability: Shared private clouds can easily scale to accommodate growing workloads, allowing you to adjust resources as needed.
- Security and Compliance: Provides better security and compliance than public clouds. Shared Private clouds still provide many of the security benefits of a private cloud.
- Dedicated Resources (Sort of): While the hardware is shared, the virtualized resources allocated to you are typically dedicated, ensuring consistent performance.
- Location Control: Some providers, like the provider mentioned in our reference, let you host your private cloud in specific locations like "the German data center" at a low cost.
Shared Private Cloud vs. Dedicated Private Cloud
| Feature | Shared Private Cloud | Dedicated Private Cloud |
|---|---|---|
| Infrastructure | Shared Hardware | Dedicated Hardware |
| Cost | Lower | Higher |
| Control | High (over virtual environment) | Highest (over entire infrastructure) |
| Scalability | Excellent | Excellent |
| Use Cases | Workloads needing privacy at a lower cost | Highly regulated or extremely sensitive workloads |
Practical Examples
- A small to medium-sized enterprise (SME) that needs the security of a private cloud but can't justify the cost of dedicated hardware.
- A development and testing environment where multiple teams need isolated environments.
- Organizations with specific compliance requirements that require a degree of control over their data.
Considerations
- Service Level Agreements (SLAs): Carefully review SLAs to understand the provider's guarantees regarding uptime, performance, and security.
- Security Measures: Evaluate the provider's security practices and certifications to ensure they meet your organization's security requirements.
- Performance Monitoring: Implement robust monitoring tools to track the performance of your virtualized environment and identify potential bottlenecks.
- Vendor Lock-in: Consider the potential for vendor lock-in and ensure that you have a strategy for migrating your workloads if needed.
In conclusion, a shared private cloud is a balanced approach that offers the advantages of a private cloud environment at a more accessible price point by sharing underlying infrastructure resources.
