Unlock predictable pricing and data control with an S3-compatible alternative designed to prevent vendor lock-in and protect your most critical assets.

Cost unpredictability is the number one pain point for IT leaders managing cloud infrastructure. Surprise egress fees and complex API charges from major providers can erode budgets by up to 80%. At the same time, ransomware attacks increasingly target backup data, making immutable storage a non-negotiable for business continuity. An enterprise-ready S3-compatible alternative offers a practical solution, combining transparent, predictable costs with the robust security of Object Lock. This approach provides a clear path to lower total cost of ownership and a built-in exit strategy.

Key Takeaways

  • Immutable cloud storage with Object Lock is a non-negotiable defense against ransomware that targets backup data.
  • Eliminating egress fees and API call costs can reduce total cloud storage expenses by 60-80%, enabling predictable budgeting.
  • An 'Always-Hot' storage architecture provides faster, more reliable data access than complex tiering models, improving backup performance by up to 20%.

Fortify Defenses with Immutable Storage

Ransomware attacks increasingly target backup infrastructure to prevent recovery. Immutable cloud storage creates a WORM (Write-Once-Read-Many) model, making your data unchangeable for a set period. This capability is a core defense for your disaster recovery plan. Our platform's Object Lock feature ensures that once written, your backup files cannot be altered or deleted by anyone. This provides an audit-ready retention policy for compliance and business continuity. Organizations using immutability report a significant improvement in their security posture. This simple feature is a non-negotiable for protecting mission-critical data. It directly addresses the primary attack vector in modern cyber threats. This protection prepares your organization for a rapid, reliable recovery.

Eliminate Surprise Fees to Predict Cloud ROI

Most IT leaders cite vendor lock-in as a top strategic risk. A key component of this trap is punitive egress fees, which make switching prohibitively expensive. Our pricing model is predictable by design, with zero egress fees and no API call costs. This transparency eliminates 60-80% of typical cloud storage expenses for data-intensive workloads. This approach makes budget planning possible again. You can retrieve your data as needed without financial penalties, preserving your negotiation power. Predictable costs ensure your total cost of ownership is dramatically lower. This economic model is built for data control and independence. It allows you to focus on value, not on avoiding hidden charges in your monthly bill.

Migrate Seamlessly with a True S3-Compatible Alternative

S3 compatibility is table stakes, but not all alternatives deliver on its promise. A true drop-in replacement requires full support for the S3 API, allowing you to migrate without application rewrites. You just change the endpoint and keep your existing tools, scripts, and workflows. This protects your past investments and reduces migration risk to nearly zero.

Our platform provides S3 compatibility that goes beyond basic operations. It includes advanced capabilities your applications depend on:

  • Object versioning for granular data protection.
  • Lifecycle management policies to automate data handling.
  • Event notifications for workflow automation.
  • Consistent API, CLI, and SDK performance.

This comprehensive support ensures your pipelines continue running without any code changes. It accelerates your time-to-value for any object storage project. This seamless transition is key to breaking free from vendor lock-in.

Access All Data Instantly with an 'Always-Hot' Architecture

Complex storage tiering often creates more problems than it solves. Policies can clash with changing access patterns, causing restore delays and surprise fees. Our 'Always-Hot' object storage model ensures all data is immediately accessible without tier-restore delays. This architecture delivers up to 20% faster backup performance with consistent low latency. This model reduces operational complexity and keeps third-party tools stable. There are no restore surprises, no API timeouts, and no hidden operational costs. An always-hot architecture simplifies your operations and strengthens recovery capabilities. It means every piece of data is ready for immediate use, a critical factor for both analytics and data backup strategies. This approach guarantees predictable performance for every workload.

Meet Enterprise Compliance with Audited Security Controls

Enterprise IT leaders require storage that meets strict regulatory and security standards. Our platform holds key enterprise-grade certifications, including SOC 2 and ISO 27001. These certifications verify our commitment to security for regulated workloads. We provide multi-layer encryption for data in transit and at rest. You maintain full control over your data and security posture. Our IAM includes granular, role-driven policies and support for external IdPs via SAML/OIDC. The console UX simplifies bucket management, permissions, and monitoring without deep API expertise. This focus on secure cloud storage gives you the tools for governance. This foundation of trust is essential for modern data management.

Enable MSP Profitability with a Predictable Cost Model

For MSPs, resellers, and system integrators, predictable margins are essential for growth. Our channel-first model was built to deliver that stability. With zero egress or API fees, you can quote BaaS and DRaaS solutions with confidence. No surprise bills means no margin erosion on your existing contracts.

Our partner console is ready for your business needs. It provides the following tools for efficient operations:

  1. Multi-tenant management with RBAC and MFA.
  2. Full automation capabilities via API and CLI.
  3. Integrated reporting for client management.
  4. Fast onboarding for you and your customers.

This cost efficiency becomes your competitive advantage. You can pass savings to customers while maintaining healthy margins. This structure allows you to build a more profitable and predictable cloud services business.

FAQ

How does Impossible Cloud save up to 80% on storage costs?

The cost savings come from a transparent pricing model with no egress fees, no API call costs, and no minimum storage durations. This eliminates the hidden charges that make up a significant portion of bills from traditional hyperscale cloud providers.


Can I use my existing backup tools with your storage?

Yes. Our platform offers full S3-API compatibility, ensuring out-of-the-box integrations with leading backup tools like Veeam and others. You can connect your existing software by simply changing the storage endpoint in your configuration.


What does 'Always-Hot' storage mean?

'Always-Hot' means all your data is stored in a single, high-performance tier and is always immediately accessible. This eliminates the delays and extra fees associated with retrieving data from slower, cheaper 'cold' storage tiers.


How does Object Lock protect against ransomware?

Object Lock applies a Write-Once-Read-Many (WORM) policy to your data. This makes your files immutable, meaning they cannot be encrypted, modified, or deleted for a retention period that you define, rendering ransomware attacks on your backups ineffective.


What compliance certifications does Impossible Cloud hold?

We hold enterprise-grade compliance certifications, including SOC 2 and ISO 27001, to ensure our platform meets strict security and operational standards for regulated workloads.


Is there a program for MSPs and resellers?

Yes, we have a dedicated partner program for MSPs, resellers, and system integrators. It features a multi-tenant management console, automation via API/CLI, and a predictable pricing model designed to ensure stable, healthy margins for your business.
