Backup

A backup stores a copy of a virtual server's data. See the technical specifications for our backup options.

Business IP

An IP-based data network solution comprised of IP connectivity (but not internet access or usage) and one or more standard IP WAN connections (such as ADSL, Ethernet Lite, Frame relay or Ethernet) for each site. A hosting port connection to your existing business IP network can be requested as a virtual server add-on.

CLUSTER

A cluster is a group of resources you need in order to run virtual servers on dedicated compute. It contains at least two blades and associated storage. Once a virtual data centre is created, a cluster can be associated with it.

Connect IP

A communication solution providing IP WAN connectivity for business customers with Next G®. Connect IP leverages Telstra's Next IP® network to interconnect branch sites. A hosting port connection can be added to your existing Connect IP network.

CPU-hour

An hour that a CPU is associated with a virtual server (e.g. a virtual server with two CPUs consumes two CPU-hours per hour).

Data import

A virtual server add-on, data import uses secure storage devices to transfer large amounts of data from in-house networks to the cloud.

DATA IMPORT STORAGE DEVICE

A storage device which is loaned to you (for a fixed fee charged per device) to assist with transferring large quantities of data to the cloud. The devices are available in a range of sizes.

DATASTORE

A VMware® vCenter Server feature, a datastore is a unit of storage assigned to a customer cluster. When a datastore is created it is added to all VMware ESXi hosts in a cluster.

Internet protection (email)

A virtual server add-on that filters incoming and outgoing email to keep spam, viruses and inappropriate content off networks.

Internet protection (web)

A virtual server add-on that provides fully managed web filtering and security to protect against malware, spyware and viruses.

IP MAN

Internet protocol metro area network is a simple way to connect offices within metropolitan areas to the cloud. A hosting port connection to your existing IP MAN network can be requested as a virtual server add-on.

IPSEC

Internet protocol security is an IP protocol framework that authenticates and encrypts IP packets to ensure the safe transfer of data.

IPsec VPN

Internet protocol security virtual private network is provides permanent secure site-to-site remote access between in-house networks and virtual servers.

IP WAN

Internet protocol wide area network is a high-quality managed service which provides a secure way to interconnect metropolitan, regional and rural offices.

PRIVATE INTERCONNECT

Your private interconnect lies between the cloud resources in your private network, and a private network connection (Telstra Next IP® network, Global IP VPN or IPsec VPN tunnel).

PUBLIC INTERCONNECT

Your public interconnect exists between the cloud resources in your public network, and the internet. Virtual servers in your public network are accessible through the internet, via your public interconnect. Your public interconnect is non-configurable.

 

R

Top

RAM-hour

An hour that a GB of RAM is associated with a virtual server (e.g. a virtual server with 2GB of RAM consumes two RAM-hours per hour).

Recovery point objective

The maximum rollback point in time to which your data is restored during data restoration.

Recovery time objective

The time taken to restore or reconfigure your equipment and start the upload of data to the target systems during the restoration process.
