Cloud computing infrastructure
OneNet carefully selects class-leading providers of the technology components required to build its own trans-Tasman computing cloud. Long-term relationships are developed with those strategic technology partners, with OneNet team members holding many advanced vendor specialty technical certifications. Further details here.
Third party hyper-scale clouds
OneNet provides cloud computing management services for Microsoft’s Azure cloud and Amazon’s Web Services cloud. The two world-leading third party hyper-scale clouds are balanced with OneNet’s own computing cloud to meet OneNet’s client requirements. The relative weighting of deployments over the three clouds will depend upon the type of work-load, required performance, cost and client management criteria.
OneNet co-locates its cloud computing equipment in five locations in New Zealand and Australia. Co-location means that OneNet rents the floor space on which its equipment is located. The data centre provider delivers secure streams of electricity, cooling and telecommunications connectivity. The data centre provider is also responsible for ensuring that those resources are always available. Physical security is also their responsibility.
OneNet owns all of the servers, storage and communications equipment, as well as all of the intellectual property, required to provide OneNet’s cloud services.
OneNet provides its cloud services from data centres located at Orbit Drive, Auckland, Te Rapa, Hamilton, Gloucester Street, Christchurch and Equinix Data Centres in Sydney and Melbourne.
The data centres from which OneNet delivers its cloud services have very high levels of physical security, detailed as follows:
- A 48-hour pre-approval process is required for any third party visitor to access the data centre.
- A photographic recording of all attendees is made, prior to entry.
- Government-issued photographic ID, such as a passport or driver’s license, is required for admission.
- Extensive CCTV (closed circuit TV) monitoring of all attendee movements and all operational space is recorded and maintained.
- High security walls and extensive physical barriers are in place to deter any unauthorised entry.
- A dedicated power feed from the local electrical substation provides certainty of power supply.
- Dual (2 N) server rack power feeds (A plus B), thus providing two independent power feeds to server racks. In this context, “N” refers to the quantity of a resource that is required to perform the task. That is, there is twice as much available (“2N”) than the quantity actually required (“N”), thus providing 100% resource backup, if one power source fails.
- Dual (2 N) UPS. A UPS (uninterruptible power supply) is essentially short-term battery storage to provide continuous power in the event of a power outage, prior to backup generators starting up and generating backup power load.
- N + 1 redundancy for the main power board, transformer and generator set. This means that there is always one spare set of resources to provide a backup in the event that the main power board, transformers or generators fail. In this context, “N+1” means that N provides all of the resource required, but if one unit fails, there is always another available on standby.
- On-site N+1 diesel generators. The diesel generating capacity is sufficient to power all demand from the data centre in the event of a failure in the supply of electricity from an external provider.
- N + 1 chillers, or air conditioning, provide redundant backup for cooling the heat generated by server racks.
- Inert gas fire protection, which suppresses any fire without destroying electronic equipment, such as servers.
- 24×7x365 on-site operational management and security staff.
- The KPIs (key performance indicators), or SLA (service level agreement) contractual obligations, for the data centre provider to maintain “up-time” are 100% for air conditioning, fire protection and physical security, while the power supply SLA is 99.995%.
