Are unpredictable cloud costs eroding your MSP margins? Hyperscaler pricing models with hidden egress and API fees make it impossible to forecast profitability for your multi-tenant storage services. Discover a predictable, EU-sovereign object storage solution designed for MSP growth.

Key Takeaways

MSPs can achieve predictable margins by choosing multi-tenant storage with a transparent pricing model that has zero egress fees, API call costs, or minimum storage durations.

A sovereign-by-design platform operating in EU-only data centers provides a key competitive advantage by ensuring GDPR compliance and eliminating CLOUD Act exposure.

Full S3-API compatibility and an 'Always-Hot' storage architecture simplify operations, reduce migration risk, and ensure seamless integration with existing backup tools.

For Managed Service Providers, delivering multi-tenant storage solutions should be a source of stable, recurring revenue. Yet, over 54% of MSPs report overspending on hyperscaler cloud services, facing complex pricing and vendor lock-in. This challenge is compounded by increasing client demand for data sovereignty and compliance with EU regulations like GDPR and NIS-2. A purpose-built multi-tenant storage MSP platform offers a path forward. It combines full S3-API compatibility for seamless integration with predictable, transparent pricing. This approach empowers MSPs to build profitable, compliant, and resilient backup and archiving services for their clients.

Escape Unpredictable Costs in Multi-Tenant Environments

Over one-third of UK MSPs identify spiraling costs as their top challenge with hyperscale providers. Traditional multi-tenant storage models often include egress fees, API call charges, and minimum storage durations that destroy profitability. These unpredictable expenses make it difficult to offer competitive, fixed-price Backup-as-a-Service (BaaS) or archive solutions. A transparent economic model eliminates these variables entirely. This allows MSPs to build services with 100% predictable margins. You can find more information on our recurring revenue models for MSPs. This financial stability is the foundation for scalable growth.

Deliver True Digital Sovereignty Under EU Law

A majority of EU decision-makers now demand European solutions for critical infrastructure. Storing client data with non-EU providers creates exposure to foreign laws like the CLOUD Act, a risk many clients can no longer accept. Our multi-tenant storage MSP platform is sovereign by design, operating exclusively in certified European data centers. It offers country-level geofencing to guarantee data residency and full GDPR compliance. This provides the legal certainty your clients in regulated industries require. Learn more about how MSPs can leverage UK-based sovereign storage. This commitment to EU data governance turns compliance from a burden into a competitive advantage.

Leverage Full S3 Compatibility for Seamless Integration

Migrating client workloads to a new platform can introduce significant risk and cost, requiring extensive code rewrites. Full S3-API compatibility eliminates this friction, protecting your clients' past investments in tools and scripts. Our platform supports not just basic S3 operations but also advanced capabilities like versioning and lifecycle management. This ensures out-of-the-box integration with leading backup tools, including collaborations with vendors like Nova Backup for MSPs. Your existing applications continue working with zero code changes. This operational continuity is critical for a smooth transition.

An S3-compatible platform offers several key advantages for MSPs:

  • It allows for the use of a vast ecosystem of existing S3-native applications and tools.

  • Automation scripts using standard API/CLI/SDKs function without modification, reducing onboarding time by over 50%.

  • It provides a clear exit strategy, preventing vendor lock-in and preserving long-term freedom of action.

  • Training for technical teams is minimized, as they can use the familiar S3 protocol they have worked with for over 15 years.

This deep compatibility simplifies every stage of the client lifecycle.

Simplify Operations with an 'Always-Hot' Storage Architecture

Complex storage tiering creates operational fragility, with 62% of companies overspending on cloud due to hidden fees. Policies for moving data between hot, cool, and archive tiers often fail during urgent restores, causing API timeouts and surprise retrieval costs. An 'Always-Hot' object storage model eliminates this complexity entirely. All data is immediately accessible, with no restore delays or tier-restore fees. This model reduces the operational burden on your team and ensures third-party backup tools remain stable. Read about the issues with tiered storage pricing. This architectural choice delivers both performance and predictability.

Provide Robust Ransomware Protection with Immutable Storage

Ransomware attacks struck 85% of organizations in the last year, making resilient backups a primary client concern. A robust multi-tenant storage MSP solution must include features to counter this threat directly. Our platform provides Immutable Storage using S3 Object Lock. This feature prevents data from being deleted or altered by anyone—including administrators or malicious actors—for a defined retention period. Immutable backups guarantee a clean, uncorrupted copy of data for recovery after an attack. This capability is a cornerstone of modern data protection strategies, like those discussed in our guide to cloud storage security. This powerful feature helps you build highly defensible BaaS offerings.

Streamline Client Management with a Partner-Ready Platform

Efficiently managing hundreds of clients requires a platform built for the channel. Our partner console is designed specifically for the multi-tenant storage MSP workflow. It provides robust tools for automation, management, and reporting to reduce your administrative overhead. Onboarding a new client can be completed in under 15 minutes. You can become an MSP partner to access these tools.

Key features in our partner console include:

  1. Multi-Tenant Management: Create and manage isolated tenants for each client from a single dashboard.

  2. Role-Based Access Control (RBAC): Implement granular, role-driven policies to enforce the principle of least privilege.

  3. Identity and Access Management (IAM): Secure accounts with MFA and integrate with external IdPs via SAML/OIDC.

  4. Automation via API/CLI: Automate provisioning, billing, and reporting to scale your operations efficiently.

These features ensure you can manage your client base securely and at scale.

Meet 2025 EU Regulations Like NIS-2 and the Data Act

The EU regulatory landscape is evolving, with two key directives impacting data storage in 2025. The NIS-2 Directive requires stricter cybersecurity processes, including supply-chain assurance and incident reporting. The EU Data Act, fully applicable from September 2025, mandates data portability and interoperability to prevent vendor lock-in. Our platform is designed to meet these requirements. We provide a clear exit path by design, ensuring you can export all data, including metadata and versions. This regulatory readiness is a key differentiator for your services. This focus on future compliance prepares your clients for what's next.
