Why Multi-cloud Storage Virtualization Matters for CIOs and CISOs

As a CIO or CISO, you manage complex data requirements that involve balancing innovation with efficiency, productivity with employee access, and cost-effectiveness with performance and security. However, in today's hybrid and multi-cloud platforms, corporate data handling and management has become even more complicated as there are various storage environments. This is where multi-cloud storage virtualization comes into play to simplify things.

Multi-cloud storage virtualization is now a crucial technology for modern CIOs/CISOs. It is a strategy that unifies the storage services of multiple cloud vendors into a single, virtualized environment. This enables organizations to benefit from each cloud provider's best features and functionalities while simplifying storage management and potentially reducing costs.

Many organizations would benefit from the ability to view and manage their on-premises and cloud storage resources in a single, unified storage pool. This would make accessing and managing everything from one central dashboard seamless. Multi-cloud storage virtualization is a game-changing technology that is here to stay. It simplifies data management, optimizes costs, boosts agility, encourages data sovereignty, and can significantly strengthen data security. 

CIOs and CISOs have different focused use cases and priorities that they focus on when considering multi-cloud storage virtualization. A CIO will look at the following:

  • Modernizing Legacy Applications: Migrate legacy applications to a more modern, cloud-based storage infrastructure without vendor lock-in.

  • Retiring legacy applications: many organizations keep costly, aging applications running for regulatory compliance requirements or due to pending or current litigation and eDiscovery. However, in many cases, the data can be migrated to a cloud to keep it available for search and reference while closing the legacy application – thereby freeing up the cost of annual hardware purchases, annual software maintenance agreements, backup and DR requirements, and costly data security requirements.  

  • Supporting Hybrid Cloud Deployments: Seamlessly integrate on-premises storage with public cloud resources for a unified storage experience.

  • Enabling Data Analytics: Leverage cloud storage solutions designed for big data analytics, facilitating insights and data-driven decision-making.

On the other hand, a CISO would be interested in multi-cloud storage virtualization for use cases related to enhancing security, mitigating risk, and improving data governance. These include:

Strengthening Security Posture: 

  • Data Defense in Depth: Leverage different cloud providers' diverse security features and controls, creating a layered defense against potential threats. This could include utilizing different encryption methods, access control policies, and intrusion detection systems across platforms.

  • Improved Threat Detection: Utilize analytics and monitoring tools offered by various cloud providers to gain a broader view of potential security risks and incidents across the entire storage infrastructure.

  • Enhanced Security Compliance: Implement multi-cloud storage to comply with specific data security regulations (e.g., PCI DSS, HIPAA, SEC) by choosing providers who demonstrate strong compliance practices and offer features aligned with regulations.

Mitigating Data Risks:

  • Increased Data Resiliency: Potentially distribute data across multiple cloud regions, ensuring redundancy and availability in case of outages or disasters. This allows for quick recovery and minimizes data loss risk.

  • Improved Disaster Recovery: Leverage multi-cloud storage for robust disaster recovery planning. Utilize recovery mechanisms to seamlessly migrate data back to the original cloud platform after a significant incident.

  • Enhanced Data Encryption: Combine encryption capabilities from different providers to ensure all data, at rest and in transit, is securely protected, further minimizing the risk of unauthorized access or data breaches.

  • Protect against ransomware: Encrypting sensitive data and storing two copies on an immutable storage tier guarantees your data cannot be opened, copied, or deleted. 

Data Governance and Control:

  • Granular Access Controls: Implement more granular and centralized access control across multiple cloud storage platforms, ensuring only authorized individuals can access specific data based on need-to-know principles.

  • Streamlined Data Auditing: Utilize auditing tools and logs offered by multiple providers to gain a comprehensive view of data access and activity across the entire storage infrastructure, simplifying compliance audits and investigations.

  • Improved Data Lifecycle Management: Implement consistent data lifecycle management policies across different cloud storage solutions, ensuring proper data classification, retention, and deletion based on organizational policies and regulations.

  • Centralized and automated data movement: Your corporate data can be automatically migrated across cloud platforms based on policies. For example, data stored on expensive tier 1 cloud storage that has not been accessed in over 12 months can be automatically moved to a less costly storage tier or different cloud platform.

  • Compliant Data Sovereignty: Many countries and government agencies have created regulations that require data created in a specific geography to remain in that geography. 

What does it take to implement multi-cloud storage virtualization successfully?

In multi-cloud storage virtualization, there are several important elements to consider. These include cloud storage services, virtualization software layer, and storage management tools that offer functions such as data migration, deduplication, data replication, and disaster recovery. CIOs and CISOs should assess the following factors before selecting a multi-cloud storage virtualization platform. Essential aspects to evaluate include: 

Technical Considerations

  • Platform Compatibility: Ensure the solution integrates seamlessly with your existing and planned storage infrastructure and applications across different cloud providers

  • Performance and Scalability: Evaluate the platform's ability to handle data volumes, access speeds, and potential scaling needs within your organization

  • Data Security Features: Assess the platform's security capabilities, including encryption, access control, auditing, external evaluations, references, and compliance support

  • Management Tools: Ensure the platform offers robust management tools for data migration, replication, deduplication, provisioning, and monitoring across various cloud environments

Cost and Pricing:

  • Pricing Models: Understand the platform's pricing structure and compare it with individual cloud storage costs to assess potential cost savings, return on investment (ROI), or pricing complexities

  • Hidden Costs: Factor in potential hidden costs like ingest and exfiltration fees, geographic replication, API calls, and management overhead associated with the platform

  • Vendor Lock-in: Avoid vendor lock-in by choosing a platform with open APIs and vendor-neutral data formats for easy migration if needed later

Organizational Factors:

  • IT Skills and Expertise: Assess your IT team's skills and readiness to manage a multi-cloud storage environment with potential complexities. Once in place, a highly rated-solution will need little or no special management

  • Change Management: Plan for potential resistance to change and implement effective communication and training strategies for user adoption. But again, with the best solution, end users should not notice the change and would not need additional training

  • Compliance Requirements: Ensure the platform supports your organization's specific data residency, data privacy regulations, and data security compliance regulations

Additional Considerations Before Purchase:

  • Vendor Reputation and Support: Choose a reputable platform vendor with a proven track record, strong customer support, recent references, and active product development

  • Community and Resources: Investigate the availability of community forums, documentation, and learning resources for the platform to support your team

  • Proof of Concepts (POCs): Conduct POCs with potential platforms to evaluate performance, functionality, and suitability for your specific needs

Storage virtualization solutions have been available for several years. However, integrating cloud platforms in the virtualization layer is relatively recent. As more and more organizations embrace digital transformation and adopt cloud computing, it is becoming increasingly important to include cloud storage virtualization platforms in your organizational strategy. Your organization can benefit greatly by adapting storage virtualization to multi-cloud environments. Increased flexibility:
