When you login to the customer portal you should add/create your SSH keys before creating any instances by visiting your Profile settings. Do not skip this step as the key is required if you wish to log-in to your remote linux/unix systems or if you wish to use the Spearhead Cloud Tools<sub>1<sub>.
* Install the [Spearhead Cloud CLI tools](https://docs.spearhead.cloud/spearhead-cli) and manage your cloud from the command line
* Continue to the [Cloud Portal](https://docs.spearhead.cloud/cloud-portal).
## Terminology
* instance(s) - an instance in the spearhead cloud may refer to:
* a hardware virtual machine
* an infrastructure container
* a Docker container
* image(s) - images contain your operating system, applications and services. Spearhead provides several images to help you get started. Some images contain complete applications and services for easy and quick deployments or start from scratch images where you can configure the applications yourself.
* Docker container images - you can connect public or private container registries to run those images on Spearhead Cloud.
* Infrastructure container images - are container native Linux and SmartOS systems running on bare-metal. These offer high performance, scalability by allowing on-line resizing and security. Take advantage of preconfigured images for many scopes such as databases and web servers.
* Hardware virtual machines - these are typical virtual machines that run using KVM. We provide these for legacy systems or workloads that cannot be deployed as containers.
* package(s) - packages define the resources allocated to an instance.
