Nebula One™

Nebula One brings the cloud to you, under your control, behind your firewall. It is an integrated hardware and software appliance providing distributed compute, storage, and network services in a unified system.

Nebula One consists of Nebula hardware and software coupled with certified industry-standard x86 servers known as Nebula Cloud Nodes to create a private cloud. The heart of the solution is the Nebula Cloud Controller, an appliance which integrates up to 40 servers.

Embedded on each controller is Nebula Cosmos™, an operating system which orchestrates services and provide end-user functionality. Nebula Cosmos simplifies administration for the entire cloud system through a unified management interface enabling end users to provision their own compute and storage resources via an intuitive self-service portal. It provides API compatibility with the OpenStack and Amazon EC2/S3 cloud platforms.

Nebula One scales and achieves high availability using multiple controllers. A Nebula Cloud Edge networking switch connects controllers together to present the Nebula One system to your IP infrastructure as a layer 3 device. In multi-controller configurations, Nebula Cosmos seamlessly orchestrates resource expansion, leaving users and admins with a singular, continuous experience across all devices.

Features and Benefits

Features Benefits
Turnkey installation and easy-to-use GUI The Nebula One system offers a simple and fast installation experience with an easy-to-use graphical user interface.
Enterprise Integration: Identity, Storage, Networking

Seamless integration with existing enterprise workflows and architecture. Straightforward way for enterprise to achieve the cost and simplicity benefits of cloud computing within the enterprise, without disruption to IT or the large investment in people, time and expertise.

  • Extend existing identity workflows into the cloud with Nebula’s support for Active Director and LDAP
  • Extend existing storage workflows with Nebula’s support for NetApp and SolidFire
  • Extend existing VLAN workflows with Nebula’s VLAN model feature
  • Extend existing monitoring tools with Nebula’s collectd support
System diagnostics support and context-sensitive help Expanded supportability through a secured, downloadable archive of system logs and diagnostic details for customer analysis, or Nebula-assisted troubleshooting. System-wide context-sensitive self-help experience, offering improved productivity and relevant, timely support.
Seamless scalability A Nebula One cloud scales from three to 40 Cloud Nodes with a single controller.
Elastic compute and storage Nebula pools all compute and local storage within the system to provide a cloud-level aggregation of resources for all users.
Self-service provisioning Users of the system are provided with quotas and limits. Within these limits, users manage their compute and storage resources, configure instances, and deploy distributed applications without additional administrator oversight.
OpenStack and AWS API compatibility The Nebula One system provides compatibility with two of the most common cloud APIs, helping to ensure portability of user workloads. Use RESTful APIs to build custom scripts that take full advantage of Nebula cloud functionality, and maintain complete interoperability between Nebula, OpenStack, and Amazon Elastic Compute Cloud (EC2) for backup, compliance, monitoring, and other integrated solutions.
Secure design and configuration Key pairs and security groups prevent unauthorized access to instances. Each component within the Nebula cloud system is security hardened before deployment. Configurable TLD-encrypted syslog output that protects Nebula One from unauthorized syslog access
Highly available control plane The control plane in a multicontroller Nebula cloud system, that orchestrates and manages instances and volumes, is distributed and fault tolerant by design.
Operations dashboard Administrators and end users can use an operations dashboard to manage and monitor the system. Detailed logs from components are aggregated into a syslog endpoint.
Scalable storage solution Nebula leverages Cloud Node local storage to provide a storage subsystem that is inexpensive and scales predictably in capacity, price, and performance.
Named-based system configuration values Nebula permits the use of resolvable services using DNA, providing support for reliable time service through NTP pooling, and other common named network services.
Support for popular server nodes Nebula One supports the Dell R720xd, Cisco C240 M3, IBM x3550 M4, HP DL380p Gen8, and SuperMicro Nebula servers.
