Eliminate unpredictable cloud bills by shifting to a transparent, S3-compatible storage model without egress fees or vendor lock-in.

As enterprise data expands into the multi-petabyte range, the conversation shifts from capacity to cost control. Traditional hyperscale cloud storage, once a symbol of efficiency, now presents a significant financial risk for many US enterprises. Unpredictable expenses like data egress fees and API call charges can inflate monthly bills by 3-5x, making budget forecasting nearly impossible. This forces IT leaders into a difficult position, trapped by vendor lock-in and proprietary systems. The solution lies in a new approach: an S3-compatible, enterprise-grade object storage model designed for cost predictability, data independence, and performance without compromise.

Key Takeaways

  • Eliminate unpredictable petabyte storage costs by choosing a model with zero egress fees and API charges, saving 60-80% compared to traditional cloud providers.
  • Ensure seamless migration and protect technology investments with a 100% S3-compatible alternative that requires no code rewrites for existing applications and tools.
  • Strengthen ransomware protection with immutable storage and Object Lock, a non-negotiable feature for securing backups and ensuring business continuity.

The Hidden Costs Driving Petabyte-Scale Budgets

Cost unpredictability is the number one pain point for 95% of enterprises managing large datasets in the cloud. The primary culprits are hidden charges that appear only after you are locked into an ecosystem. Egress fees, the cost to move your own data, can add up to $0.09 per GB for transfers between regions.

For a company moving just 500 TB of data for analytics or disaster recovery testing, this can create an unplanned expense of over $45,000. API call charges add another layer of complexity, turning routine backup operations into thousands of costly micro-transactions. These variable expenses frequently cause total costs to exceed storage fees by 3-5x.

This pricing model creates significant vendor lock-in, a top concern for IT leaders. The prohibitive cost of data retrieval makes switching providers a multi-million-dollar decision, stifling flexibility and strategic control. Organizations need a more transparent model to manage cloud storage pricing effectively.

Achieve 60-80% Savings with a Predictable Cost Model

A predictable financial model is essential for managing petabyte storage costs. Impossible Cloud eliminates the primary sources of budget overruns by design. We charge zero fees for data egress and zero fees for API calls, creating a transparent structure that saves organizations 60-80% on typical cloud storage expenses.

This "predictable by design" approach allows for precise budget forecasting, even with dynamic workloads. With no minimum storage duration requirements, you only pay for what you use for as long as you need it. This direct economic model removes the financial penalties associated with accessing your own data.

By removing these barriers, enterprises regain control over their data and their budgets. This shift allows for the implementation of robust backup and disaster recovery strategies without the fear of runaway costs, making it a truly more affordable storage alternative. This financial predictability is the foundation of a modern data strategy.

Demand S3 Compatibility That Delivers Performance

True S3 compatibility is more than a checkbox; it is a requirement for a seamless transition and continued operational stability. Our platform offers full S3-API compatibility, ensuring your existing applications, scripts, and backup tools work without any code rewrites. You simply change the endpoint, and your workflows continue to function, protecting years of investment in your current software stack.

Performance at scale is equally critical. We utilize an "Always-Hot" object storage model, where all data is immediately accessible without the delays and restore fees common with tiered storage architectures. This approach delivers up to 20% faster backup performance and consistent low latency for read/write operations. Key features include:

  • Full support for advanced S3 capabilities like versioning and lifecycle management.
  • An architecture that eliminates single points of failure for high availability.
  • Consistent performance for mixed workloads, from millions of small files to large archives.
  • Out-of-the-box integrations with leading backup tools like NovaBackup.

This commitment to being a drop-in S3 replacement ensures that you gain cost efficiency without sacrificing the performance your enterprise demands. This robust architecture provides the reliability needed to secure your most critical assets.

Implement Ransomware Protection with Immutable Storage

With backup infrastructure now a primary target for cyberattacks, robust security is non-negotiable. A recent survey found that 94% of IT leaders in the United States, the UK, France, and the US already use or plan to implement immutable storage within the next year. Our platform provides Immutable Storage and Object Lock capabilities, creating a tamper-proof copy of your data that cannot be altered or deleted by anyone, including administrators.

This feature is your last line of defense against ransomware, ensuring you always have a clean, recoverable copy of your data. Immutable backups mean the difference between a minor disruption and a catastrophic business failure. This level of security is essential for meeting modern cyber insurance requirements.

Our security framework is validated by enterprise-grade compliance certifications, including SOC 2 and ISO 27001. We provide multi-layer encryption for data in transit and at rest, alongside robust Identity and Access Management (IAM) with MFA and role-based access control. This focus on security allows you to build a resilient defense against evolving threats.

Enable MSPs with Predictable Margins and Simplified Management

For Managed Service Providers (MSPs), predictable costs directly translate to predictable margins. The elimination of egress and API fees allows MSPs to price their Backup-as-a-Service (BaaS) and DRaaS offerings competitively while protecting their profitability. There are no surprise bills to erode margins, enabling you to quote with confidence every time.

Our partner-ready platform is designed for the channel. It provides the tools needed to efficiently manage multiple clients and scale operations. Key features for MSPs include:

  1. A multi-tenant partner console with robust role-based access control (RBAC) and MFA.
  2. Full automation capabilities via a comprehensive API and CLI.
  3. Simplified compliance management for serving clients in regulated industries.
  4. Fast onboarding and dedicated local support for North American partners.

This channel focus provides a competitive advantage, allowing partners to pass savings to customers or increase profitability on existing contracts. By simplifying operations, we help you focus on growing your business.

Build a Practical Exit Strategy with Data Portability

Vendor lock-in is a strategic risk that limits your negotiating power and long-term agility. A true cloud partnership should include a built-in exit strategy. Our platform is designed around open standards and data portability, ensuring you always remain in control of your data. The combination of 100% S3 API compatibility and zero egress fees gives you the freedom to move your data whenever you choose, without financial penalties.

An exit strategy is not an afterthought; it is a core component of data independence. By design, our architecture ensures you can retrieve petabytes of data efficiently and affordably. This preserves your freedom of action and ensures you are never trapped by a single provider.

This commitment to no hidden costs and open standards is the ultimate guarantee against lock-in. It empowers you to make infrastructure decisions based on what is best for your business, not on the restrictive policies of your vendor.
