Community Cloud

A community cloud is shared infrastructure used by organizations with similar requirements, offering cost-sharing benefits and specialized compliance solutions through software-defined technologies.

Community Cloud

A community cloud is a multi-tenant cloud infrastructure shared by several organizations with similar computing needs. The cloud infrastructure can be managed by the organizations or a third-party cloud service provider. The community cloud model is suitable for organizations that have shared concerns, such as regulatory compliance, security, and performance requirements.

Characteristics of Community Cloud

• Shared Infrastructure: The cloud infrastructure is shared by multiple organizations with similar computing needs.
• Managed by Organizations or Third-Party: The cloud infrastructure can be managed by the organizations or a third-party cloud service provider.
• Shared Concerns: Organizations in the community cloud have shared concerns, such as regulatory compliance, security, and performance requirements.
• Cost Sharing: Organizations in the community cloud can share the costs of the cloud infrastructure, making it cost-effective.
• Scalability: The cloud infrastructure can be scaled up or down as needed, making it flexible.

software-defined community cloud

A software-defined community cloud is a type of community cloud infrastructure that leverages software-defined technologies to manage and optimize resources. This approach allows for greater flexibility, automation, and efficiency in managing the cloud environment. Here’s a breakdown of what it entails and its counterparts:

Software-Defined Community Cloud

A software-defined community cloud uses software-defined networking (SDN), software-defined storage (SDS), and software-defined data centers (SDDC) to create a virtualized and automated cloud environment. This setup allows organizations to dynamically allocate resources, automate management tasks, and optimize performance based on their specific needs.

Key Features

• Automation: Automates resource provisioning, management, and scaling, reducing the need for manual intervention.
• Flexibility: Offers the ability to quickly adapt to changing requirements and workloads.
• Efficiency: Optimizes resource usage and reduces operational costs through automation and virtualization.
• Customization: Allows organizations to tailor the cloud environment to their specific regulatory, security, and performance requirements.

Counterparts of Software-Defined Community Cloud

1. Traditional Community Cloud:

   • Managed using conventional IT infrastructure and management practices.
   • May involve more manual processes for resource allocation and management.
   • Typically less flexible and automated compared to software-defined approaches.

2. Public Cloud:

   • A cloud environment where resources are shared among multiple users and managed by a third-party provider.
   • Offers high scalability and cost-effectiveness but may not meet specific regulatory or security requirements for certain organizations.

3. Private Cloud:

   • A cloud environment dedicated to a single organization, providing greater control over resources and security.
   • Typically more expensive and resource-intensive to manage compared to community clouds.

4. Hybrid Cloud:

   • Combines elements of public and private clouds, allowing organizations to leverage the benefits of both.
   • Offers flexibility in resource allocation and management but can be complex to implement and manage.

Software-Defined Community Cloud as a New Type of Government Cloud

In Google Cloud Platform (GCP), a project is a unique collection of basic infrastructure components. These components, known as infrastructure primitives, include virtual machines (VMs), persistent disks, storage buckets, and more. Projects are considered global resources, meaning they can use infrastructure components from any region or zone.

Each project is separate and distinct from other customers’ projects. The underlying resources, like hypervisors and storage blocks that support Google Cloud Storage (GCS), are isolated to ensure security and privacy. This isolation is achieved through logical and cryptographic methods.

According to NIST SP 800-145, a Private Cloud is defined as:

Cloud infrastructure that is exclusively used by a single organization with multiple users (such as different business units). It can be owned, managed, and operated by the organization itself, a third party, or a combination of both, and it can be located on-site or off-site.

When a project is created in GCP, the infrastructure components assigned to it are restricted to that specific project. This restriction creates a secure enclave for each project.

When these project-specific private cloud enclaves are combined with Assured Workloads constraints—such as data residency, support staff attributes, and security controls specific to a community—they form software-defined community clouds.

Advantages of a Software-Defined Community Cloud

Google Cloud’s approach offers several advantages, including the ability to meet security and compliance standards effectively. Access to new hardware, services, and enhancements to existing services is quicker compared to traditional community clouds. The onboarding and availability of new cloud technologies are also expedited. This model enhances overall efficiency due to the extensive infrastructure available to the community, leading to better availability and performance. Additionally, security improvements can be scaled and deployed more rapidly.

Conclusion

A software-defined community cloud provides a modern, automated approach to managing shared cloud resources, offering benefits in flexibility, efficiency, and customization. Its counterparts, such as traditional community clouds, public clouds, private clouds, and hybrid clouds, each offer different advantages and trade-offs depending on an organization’s specific needs and requirements.
