Frequently asked questions
What is 1STACK?
1STACK is a Sovereign Local Cloud service available in Singapore and Malaysia, jointly developed by Starview Technologies and CloudSigma. It delivers enterprise-grade cloud infrastructure across Private, Hybrid, Private Managed, and Public Cloud models. Built on proven KVM and VMware technologies, 1STACK emphasizes performance, control, and flexibility—without vendor lock-in or premium pricing.
What is a Sovereign Local Cloud?
A Sovereign Local Cloud is a cloud infrastructure where all data—including compute, storage, and metadata like logs and configurations—is processed and stored within a specific country’s borders. It operates under that country’s jurisdiction alone, offering assurance against foreign data access or legal overreach.
What makes 1STACK a "Sovereign" cloud?
1STACK qualifies as a sovereign cloud because its infrastructure is physically hosted within secure data centers in Singapore (planned) and Malaysia. This ensures local storage and processing of all data, governed strictly by local laws. It explicitly avoids foreign legal entanglements like the US CLOUD Act, preserving data sovereignty.
What is the US CLOUD Act and how does 1STACK protect against it?
The US CLOUD Act compels US-based tech companies to hand over user data even if stored abroad. 1STACK is operated through a Singaporean-Swiss partnership, placing it outside the jurisdiction of US law. This structure prevents US authorities from accessing customer data, ensuring it remains protected under Singaporean or Malaysian law only.
Who needs a Sovereign Cloud?
Organizations handling sensitive, regulated, or mission-critical data—such as government agencies, financial institutions, healthcare providers, and AI/ML developers—need a sovereign cloud. It ensures compliance with data localization laws and maintains national control over critical information assets.
What are the key benefits of using a sovereign cloud like 1STACK?
1. Compliance with data protection laws like Singapore’s PDPA.
2. Security against unauthorized foreign surveillance or access.
3. Risk Reduction through geopolitical and legal containment.
4. Trust & Transparency with regulators, partners, and customers.
Is 1STACK part of CloudSigma's global cloud federation?
Yes. 1STACK is a federated location within CloudSigma’s global partner network. While it operates as a sovereign platform, it benefits from CloudSigma’s global R&D, security updates, and operational excellence. Customers also gain optional access to a broader international deployment footprint.
Can a sovereign cloud be a hybrid cloud?
Absolutely. 1STACK supports secure hybrid deployments. It can integrate directly with on-premises infrastructure, allowing you to burst workloads into the cloud, implement disaster recovery strategies, or balance performance needs—all while retaining local data sovereignty.
Who is responsible for data compliance on a sovereign cloud?
Compliance is a shared responsibility. 1STACK ensures the infrastructure meets legal and security standards (like ISO 27001), but customers are responsible for their application configurations and data practices in accordance with laws such as the PDPA.
How secure is 1STACK?
1STACK is built on ISO 27001-certified infrastructure and has undergone SOC 2 Type II audits, validating its security, availability, and confidentiality practices. The CloudSigma-powered platform also complies with ISO 27017 and 27018, offering assurance for cloud-specific and personal data protections.
Does 1STACK comply with PDPA and other local laws?
Yes. 1STACK is purpose-built for compliance with data protection frameworks like Singapore’s PDPA and Malaysia’s equivalent. By guaranteeing local residency and sovereignty, it simplifies compliance and reduces legal complexity for customers.
How does 1STACK handle data privacy according to GDPR?
While primarily focused on local compliance, the platform is also GDPR-ready. CloudSigma offers a Data Processing Agreement (DPA), allowing customers to meet EU GDPR obligations with principles like privacy by design, data minimization, and cross-border control built-in.
What is the STAR Registry and is 1STACK part of it?
The STAR Registry, maintained by the Cloud Security Alliance, lists cloud providers that follow best practices in security, trust, assurance, and risk. The underlying CloudSigma platform is registered, demonstrating transparency and robust security governance.
How does 1STACK ensure physical security of its data centers?
1STACK leverages top-tier data centers like Equinix, which employ:
- 24/7 on-site security
- Biometric access control
- Multi-layer surveillance systems
- Strict access and entry protocols
These facilities offer world-class physical security for cloud hardware.
What tools are available for managing user access and permissions?
1STACK offers fine-grained access control via Access Control Lists (ACLs) and enforces Multi-Factor Authentication (MFA). This empowers administrators to follow the principle of least privilege, enhancing overall security posture.
Does 1STACK offer protection against DDoS attacks?
Yes. 1STACK features built-in DDoS mitigation, constant traffic monitoring, and a 24/7 Network Operations Center (NOC) to detect and neutralize malicious threats in real time.
Can I get audit logs on 1STACK?
Yes. Detailed audit logs and API activity records are available. These logs provide full traceability for operational and security events—essential for compliance, troubleshooting, and incident response.
How does 1STACK ensure tenant isolation in the multi-tenant cloud?
Using KVM and VMware hypervisors, 1STACK provides strong isolation between customer workloads. Each tenant operates within a secure, segregated environment, preventing unauthorized cross-access or resource leakage.
Is the management plane separated from the user plane for security?
Yes. 1STACK maintains a clear architectural separation between the management plane (administrative controls) and the user plane (customer workloads). This limits exposure, enhances security, and ensures strong governance over cloud control functions.
