Machine Types
This page gives technical specifications for the machines available on Semaphore Cloud.
Overview
A machine type defines what virtualized hardware to use in your agents.
The machines described in this page only apply to Semaphore Cloud. You can add more types of machines using self-hosted agents.
Linux machines
Linux machines are provided in four generations. The following table shows what operating systems each generation supports and if they support Docker environments.
| Generation | OS Supported | Docker environments |
|---|---|---|
| E1 | Ubuntu 20.04 | Yes |
| E2 | Ubuntu 22.04 Ubuntu 20.04 | Yes |
| F1 | Ubuntu 22.04 Ubuntu 20.04 | Yes |
| R1 | Ubuntu 22.04 ARM | No |
E1 generation
This is the entry-level, cost-effective machine type. E1s are a good choice for less compute and memory intensive tasks.
Implementation details:
- CPU: hyperthreaded on a 3.4GHz Max Turbo 4.0GHz Intel® Core™ i7
- Memory: DDR4 RAM
- Disk: RAM drive (DDR4)
The E1 generation is presented in the following types:
| Type | Virtual CPUs | Memory (GB) | Disk (GB) |
|---|---|---|---|
e1-standard-2 | 2 | 4 | 25 |
e1-standard-4 | 4 | 8 | 35 |
e1-standard-8 | 8 | 16 | 45 |
E1 Generation machine types can be paired with:
E2 generation
The E2 generation balances power with cost. It is a good choice for most tasks.
Implementation details:
- CPU: hyperthreaded on a 3.6GHZ AMD Ryzen 5 3600
- Memory: DDR4 RAM
- Disk: NvME storage
The E2 generation is presented in the following types:
| Type | Virtual CPUs | Memory (GB) | Disk (GB) |
|---|---|---|---|
e2-standard-2 | 2 | 8 | 45 |
e2-standard-4 | 4 | 16 | 65 |
E2 machines can also be paired with:
F1 generation
This generation is intended for compute-intensive tasks. They provide the most performance amongst the machines offered in Semaphore Cloud.
Implementation details:
- CPU: hyperthreaded on a 4.6GHz 12th generation Intel i5 125000
- Memory: DDR4 RAM
- Disk: NvME storage
The F1 generation is presented in the following types:
| Type | Virtual CPUs | Memory (GB) | Disk (GB) |
|---|---|---|---|
f1-standard-2 | 2 | 8 | 45 |
f1-standard-4 | 4 | 16 | 65 |
F1 machines can also be paired with:
R1 generation
These are ARM machines. They currently in the Technical Preview stage. If you're interested in trying them out, please contact our support team.
Implementation details:
- CPU: emulated ARM on Ampere Altra Q80-30
- Memory: DDR4 RAM
- Disk: NvME storage
The r1 generation is presented in the following types:
| Type | Virtual CPUs | Memory (GB) | Disk (GB) |
|---|---|---|---|
r1-standard-4 | 4 | 10 | 65 |
R1 Generation machine types can only be paired with:
ubuntu2204ARM version
