What is community cloud?

Overview

A community cloud is a specialized deployment model of cloud computing that bridges the gap between public and private clouds. In this model, cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns, such as mission, security requirements, policy, and compliance considerations. Unlike public clouds where resources are available to any paying customer, community clouds restrict access to vetted member organizations within the community.

Community clouds are particularly valuable in industries and sectors where organizations face similar regulatory burdens, security standards, or operational requirements. Examples include government agencies, healthcare institutions, financial services firms, and educational organizations. The shared nature of the infrastructure allows participating organizations to benefit from economies of scale while maintaining the security and compliance controls necessary for their specific industry vertical.

Key Characteristics

• Shared Infrastructure: Resources such as servers, storage, and networking are shared among multiple organizations rather than dedicated to a single tenant.
• Community Focus: Access is restricted to organizations within a defined community that share common objectives and requirements.
• Collaborative Management: Responsibility for management and oversight may be distributed among member organizations or delegated to a third-party provider specializing in community clouds.
• Regulatory Alignment: The cloud is designed to meet industry-specific compliance standards and regulatory frameworks applicable to all member organizations.
• Cost Sharing: Infrastructure, maintenance, and operational costs are distributed among participating organizations, reducing individual expenses compared to private cloud deployments.

How Community Clouds Work

Community clouds operate through a collaborative governance model where member organizations collectively define policies, security standards, and operational procedures. A community cloud can be managed through several approaches:

1. Member-Managed: One or more organizations within the community manage the cloud infrastructure and services for all members.
2. Third-Party Managed: An external cloud provider specializes in building and managing community clouds for specific industry verticals, handling day-to-day operations while adhering to community-defined policies.
3. Hybrid Governance: A combination of member input and third-party management, where strategic decisions are made collaboratively but operational management is outsourced.

The infrastructure itself may be hosted on-premises, off-premises, or a combination of both. Member organizations typically access shared services and applications through standard cloud interfaces, APIs, and management portals while maintaining compliance with community and regulatory requirements.

Common Use Cases and Applications

Government Sector: Government agencies at federal, state, and local levels often use community clouds to share infrastructure while maintaining compliance with government security standards such as FedRAMP (Federal Risk and Authorization Management Program) and FISMA (Federal Information Security Management Act).

Healthcare Industry: Healthcare organizations leverage community clouds to share electronic health records (EHR) systems, medical imaging storage, and clinical decision support tools while maintaining HIPAA (Health Insurance Portability and Accountability Act) compliance and patient data privacy.

Financial Services: Banks, credit unions, and investment firms use community clouds for secure data sharing, regulatory reporting, and compliance with standards like PCI DSS (Payment Card Industry Data Security Standard) and SOX (Sarbanes-Oxley Act).

Education Sector: Universities and educational institutions share research infrastructure, collaborative computing resources, and student information systems through community clouds while maintaining FERPA (Family Educational Rights and Privacy Act) compliance.

Public Health: Health departments and epidemiological research institutions use community clouds for disease surveillance, public health data analysis, and emergency response coordination.

Advantages of Community Clouds

• Cost Efficiency: Shared infrastructure and operational costs reduce expenses for individual organizations compared to dedicated private clouds.
• Industry-Specific Compliance: Purpose-built controls and standards ensure regulatory compliance specific to the community's industry vertical.
• Enhanced Security: Restricted access to community members and collaborative security policies provide higher security than public clouds while reducing complexity compared to private clouds.
• Collaboration: Member organizations can more easily share data, applications, and services with trusted partners in the community.
• Scalability: Shared resources can scale to meet growing demands of the community without individual organizations maintaining excess capacity.
• Data Sovereignty: Community clouds can be designed to maintain data within specific geographic regions or compliance jurisdictions.

Disadvantages and Challenges

• Governance Complexity: Managing a community cloud requires consensus and coordination among multiple stakeholders with potentially conflicting priorities.
• Limited Flexibility: Community policies and shared infrastructure constraints may limit customization options for individual member organizations.
• Potential Conflicts: Disagreements between member organizations regarding security policies, resource allocation, or service pricing can create operational challenges.
• Shared Responsibility: When organizations collectively manage the cloud, responsibility and accountability for security incidents or service failures may become unclear.
• Smaller Scale: Compared to large public cloud providers, community clouds may have fewer resources and less advanced automation, potentially resulting in higher per-unit costs.

Community Cloud vs. Other Deployment Models

Public Cloud: Public clouds serve unlimited customers; community clouds serve a restricted community. Public clouds have lower costs for individual users but less industry-specific compliance controls. Community clouds provide better governance and regulatory alignment for specific sectors.

Private Cloud: Private clouds are dedicated to a single organization; community clouds are shared among multiple organizations. Private clouds offer maximum control and customization but require full investment and management. Community clouds balance cost, control, and community benefit.

Hybrid Cloud: Hybrid clouds combine on-premises and cloud resources; community clouds can be hybrid but are defined by their community governance model rather than their deployment topology.

Best Practices for Community Cloud Deployment

• Establish Clear Governance: Define decision-making processes, dispute resolution mechanisms, and policy consensus procedures among member organizations.
• Document Service Level Agreements (SLAs): Create detailed SLAs that address performance, availability, security, and support expectations for the community.
• Implement Robust Security: Deploy comprehensive security controls addressing both technical security and community-specific regulatory requirements.
• Design for Compliance: Build audit, logging, and reporting capabilities that satisfy compliance requirements for all member organizations.
• Establish Data Governance: Create clear policies regarding data ownership, access rights, data retention, and data disposal within the shared environment.
• Plan for Scalability: Design infrastructure to accommodate growth in the number of member organizations and increased data volumes.
• Create Communication Channels: Establish regular communication mechanisms for addressing operational issues, security concerns, and strategic planning among member organizations.

Real-World Examples

Microsoft Dynamics 365 Government Community Cloud: Designed specifically for U.S. government agencies and their contractors, providing CRM and ERP capabilities while meeting FedRAMP requirements.

Salesforce Government Cloud: Purpose-built for government agencies requiring strict compliance with security standards and restricted data residency.

Amazon Web Services (AWS) GovCloud: While primarily a government cloud, it demonstrates community cloud principles by restricting access to authorized government entities and contractors.

Health Information Exchanges (HIEs): Many HIEs operate as community clouds, allowing multiple healthcare organizations to share and access patient health information securely and compliantly.

Future Trends

Community clouds are evolving to address emerging needs including increased emphasis on data sovereignty, blockchain-based governance for improved transparency, enhanced automation for regulatory compliance, and integration with edge computing for distributed communities. Organizations increasingly recognize community clouds as a strategic approach to balancing collaboration, compliance, and cost efficiency within specific industry verticals.
