Instance (Virtual Server)
An Instance is a virtual server running on FPT Cloud's cloud computing infrastructure, allowing you to deploy applications, store data, and run compute workloads without managing physical hardware.
Two Infrastructure Types: Specific and General
FPT Cloud provides two VPC types with different underlying infrastructure, which directly affects the feature set available to Instances within each VPC.
Specific VPC runs on VMware infrastructure. This VPC type offers the most complete feature set, including manual Snapshot, Clone, Template, GPU, and Floating IP. It is suited for workloads that require high performance or need Instance backup and replication capabilities.
General VPC runs on OpenStack infrastructure. This type supports creating Instances from Snapshot images and from NAT Instances, and also allows attaching external Storage Disks with Snapshot and Tag support. However, General VPC does not have a manual Snapshot tab and does not support Clone, Template, or GPU.
Note: The portal displays "Specific" and "General" — the underlying technical infrastructure names (VMware, OpenStack) do not appear in the user interface.
Instance Lifecycle
An Instance goes through several states during its operational life:
Stable states:
RUNNING— The Instance is running and ready to accept connections.STOPPED— The Instance is fully powered off. Some operations such as Resize and Add GPU can only be performed in this state.ERROR— The Instance has encountered an error.
Transient states:
When an operation is being executed, the Instance transitions to the corresponding action state: CREATING, STARTING, STOPPING, RESIZING, and similar states. During this time, other operations are blocked — the portal will display a notification and disable action buttons until the current action is complete.
Note: If an Instance is stuck in a transient state for an extended period, contact FPT Cloud support for assistance.

Some features related to Instances are managed in separate modules:
- Floating IP — Allocating and attaching public IP addresses is done in the Floating IP module, not in the Instance module.
- Security Group — Firewall rules are configured in the Security Group module and attached to an Instance at creation time or afterward.
- Tag — Resource labeling is managed in the Tag module.
