Compute C2 Burst

General purpose virtual servers for light workloads

Compute C2 Burst provides virtual servers that are suited for light-weight usage that may occasionally have more demands on CPU. Commonly these are test, development, or proof of concept environments, but could be any workload that has a low average CPU load over time. Compared to our main C1 or C3 virtual servers they are significantly cheaper to run, and are still provided on a consistent per-hour cost regardless of CPU usage.

They are suitable for production workloads that have low CPU demands, and have the same levels of redundancy as our main compute types.

Note: These virtual servers are currently only available in the "nz-por-1" region.

Compute C2 Burst Features

Intel Xeon 'Skylake' Processors

Our Compute C2 Burst virtual servers are powered by Intel Xeon 'Skylake' CPUs, providing strong compatibility and performance for general purpose workloads. Full support for x86 64-bit operating systems as expected from modern virtual server hosting.

Burstable CPU

Every server has a minimum CPU available, but can burst into more CPU cycles where available and needed.

Low cost, small servers

Compute C2 Burst covers smaller server sizes at a low price, from 1 to 8 vCPU with a range of minimum CPU time, and from 0.5GB to 32GB of RAM.

No overage charges

When bursting into additional CPU, we don't charge you for those extra cycles. We don't artifically limit your CPU unless there are no spare cycles.

Fast Networking

All Compute C2 Burst virtual servers have access to 10Gbit/s networking and advanced networking capabilities such as Security Groups.

Windows SQL Server Web Edition Images

Windows OS and SQL Server Web Edition images are provided and supported by Silicon Systems. The license bundled with these images is charged on the number of vCPU the C2 Burst instance has, in increments of 2 vCPU, with a minimum of 4 vCPU charged, at $0.0339 per 2 vCPU per hour, in addition to the Windows Image charges above.

For example, a c2-burst.c4r16 SQL Web image is charged $0.3949 for this instance with a Windows OS license per hour and a further $0.0678 per hour for SQL Server Web Edition licenses, for a total of $0.4627 per hour excluding GST.

Note: No discounts apply to the license part of these charges. These images are not supported by Catalyst Cloud, support is provided by Silicon Systems. There are minimum vCPU and RAM requirements for SQL Server Web Edition which need to be met, you will be charged even if the size you have chosen does not meet SQL Web Edition's minimum sizes.
