# Launch instance

> Provision a server on Nubis Compute with the right image, size, access model, and network posture.

## Start with workload intent, not with the biggest size

Launching well on Nubis Compute means matching the server to the workload: where it should run, how it should be accessed, what data it needs, and how it should be protected on day one.

## Launch checklist

<Steps>
  <Step title="Select the project and region">
    Put the instance in the project that owns the workload and choose the region closest to users or dependent services.
  </Step>

  <Step title="Choose the image and size">
    Pick the operating system and instance size that match the runtime and expected load, then plan to revisit sizing after real traffic arrives.
  </Step>

  <Step title="Define access">
    Attach the right SSH key pair, decide whether the instance needs a public entry point, and keep private workloads private by default.
  </Step>

  <Step title="Plan storage and bootstrap">
    Decide whether the root disk is enough or whether the workload needs dedicated attached disks and a cloud-init bootstrap path.
  </Step>

  <Step title="Review security before launch">
    Confirm VPC placement, subnet choice, traffic rules, and backup expectations before the server is created.
  </Step>
</Steps>

## Decide these inputs before clicking create

* Instance name and ownership
* Region and environment
* Image or template
* CPU, memory, and disk needs
* SSH access model
* Private networking and ingress exposure
* Backup and recovery posture
