At a Glance: What Atlassian Isolated Cloud Means for Secure Cloud Adoption

Atlassian Isolated Cloud is a single-tenant cloud deployment model built for organizations with elevated security, compliance, and data sovereignty needs. Launching in 2026, it offers complete tenant isolation, dedicated resources, and advanced governance—combining the control of Data Center with the agility of Atlassian Cloud. In this blog, Oxalis breaks down how Isolated Cloud compares to Government Cloud and Data Center, who it’s built for, and how highly regulated enterprises can modernize with confidence.

For highly regulated organizations, cloud adoption is no longer a question of if—it’s a question of how to do it securely, confidently, and without sacrificing control.

At Team ’25, Atlassian introduced a powerful new option to meet that challenge: Atlassian Isolated Cloud.

Set to launch in 2026, Isolated Cloud is designed for enterprises and public sector agencies that need all the innovation of Atlassian Cloud—but with the added assurance of complete tenant isolation, advanced customization, and increased governance.

At Oxalis, we’ve helped clients in defense, government, and critical infrastructure navigate the complexities of cloud modernization. Here’s what you need to know about Isolated Cloud, how it compares to other deployment models like Government Cloud and Data Center, and how to decide what’s right for your organization.

What is Atlassian Isolated Cloud?

Atlassian Isolated Cloud is a single-tenant cloud environment fully managed by Atlassian, designed for customers with heightened security, compliance, or data residency needs.

Key Features:

  • Complete tenant isolation: Your infrastructure is physically and logically separate from all other Atlassian customers.
  • Dedicated compute and storage resources: Eliminates shared resource concerns and reduces potential exposure risk.
  • Support for custom compliance requirements: Designed to accommodate industry-specific and national regulations not addressed by shared SaaS environments.
  • Advanced governance: More granular control over access, data handling, and system configurations.
  • Managed by Atlassian: You get the benefits of cloud—scalability, performance, uptime—without needing to manage the infrastructure yourself.

This model offers a compelling middle ground: the control of a private instance with the convenience of a cloud-native platform.

How Is Isolated Cloud Different from Government Cloud?

Both solutions are built with security and compliance in mind—but they serve different use cases.

FeatureGovernment CloudIsolated Cloud
Hosting EnvironmentU.S.-based, multi-tenantSingle-tenant, fully isolated
Compliance LevelFedRAMP Moderate (available); High & IL5 (planned)Supports advanced/custom compliance (including global needs)
Deployment TimelineEarly Access nowLaunching in 2026
Best ForU.S. federal agencies and contractorsAny enterprise requiring strict data sovereignty, full tenant isolation, or custom regulatory adherence
Why Atlassian Government Cloud is the Future for Public Sector Teams

In Short:

  • Government Cloud is ideal for U.S. federal agencies.
  • Isolated Cloud is broader—it supports private sector, defense contractors, international agencies, and any organization with global compliance or segregation requirements.

How Is It Different from Data Center?

Atlassian Data Center has long been the go-to solution for customers requiring control, custom hosting, or on-prem deployments. So where does Isolated Cloud fit?

Use CaseOrganizations with strict on-prem mandates or no cloud accessOrganizations ready for cloud, but needing high isolation and control

Why Atlassian Isolated Cloud It Matters:

Isolated Cloud is ideal for organizations that want to modernize securely—moving away from legacy infrastructure while preserving strict control over their environment.

It also aligns with Atlassian’s long-term direction: as support for Data Center products winds down, Isolated Cloud offers a forward-looking, compliant cloud path.

Who Is Isolated Cloud For?

Isolated Cloud is designed for organizations where data sensitivity, sovereignty, or compliance is non-negotiable:

  • Defense and National Security Agencies
  • Aerospace and Maritime Contractors
  • Global Financial Institutions
  • Healthcare and Life Sciences
  • Critical Infrastructure Providers
  • SLED Agencies with State-Specific Hosting Requirements

If your teams are working in environments where “good enough” isn’t secure enough, Isolated Cloud offers the confidence and control you need—without losing the velocity of cloud innovation.
