A virtual machine (VM) is a computer within a computer: an isolated software environment with its own operating system. It lets you test software, run applications, or perform analytics without affecting the main system. section 7.3.2
Moving analytics to the cloud
Ask: “How can I deploy my calculation to the cloud? Provide me with a walkthrough.” A single VM can run analytics much like a local PC, usually without code changes. This offers a moderate increase in computing power, but less than a distributed cluster. section 7.3.2
Treat a VM as a starting point, then check whether the workload requires more:
- Customize the environment or add resources for the specific workload. section 7.3.2
- Consider managed data processing or serverless services when one VM is insufficient. section 7.3.2
- Verify deployment instructions because cloud-provider interfaces and steps change. section 7.3.2
