Compute C3 virtual servers are suitable for most workloads, from production to development and testing. They feature high performance CPUs with balanced RAM configurations, all fully reserved and not shared between VMs. They are the best choice for production workloads due to their predictable behavior, performance, and reliability.

General purpose virtual servers for common workloads
Compute C3 Features
Intel Xeon 'Sapphire Rapids' Processors
C3 virtual servers are powered by Intel Xeon Platinum 'Sapphire Rapids' CPUs, providing modern CPU instructions such as AVX512-FP16 vector processing, and AMX for matrix processing used in AI/ML inferencing on CPUs. Fully supported by modern 64-bit x86 operating systems.
Fully dedicated resources
Virtual CPUs and memory are fully reserved and never shared with another VM, no oversubscription and no sharing of caches or execution. Virtual CPUs are "pinned" to specific physical CPUs to ensure low latency in execution.
Broad Virtual Server Sizing
Compute C3 covers sizing from 4 to 96 vCPU, with a consistent amount of memory per vCPU over the whole range.
High-speed Networking
All Compute C3 virtual servers have access to 25GBit/s networking, and benefit from all the features of our Networking services including Security Groups.
Billed By The Hour
All Compute C3 virtual servers are billed on an hourly basis, pay for what you use and you're not locked into long term commitments. Shelve unused servers and pay no compute charges, able to be unshelved to be used when needed.
Prices
Compute C3 prices include the basic compute service for each virtual server. Operating System licenses depend on the image used to create the virtual server, and may be in addition to these charges. For further information see Bundled OS Licenses for Compute.

Notes:
- Monthly prices are based on an approximation of 730 hours per month. Actual price charged each month depends on the number of hours in the month.
- All licenses required are your responsibility to obtain and comply with where needed, whether the image is provided by Catalyst Cloud or you have uploaded an image. See Bundled OS Licenses for Compute.
