Compute Instance

A Compute Instance is a virtual server in the cloud that functions similarly to a physical computer. It has its own CPU, memory, and storage, allowing you to install software, run applications, or host websites. Compute Instances are a fundamental component of ZSoftly Public Cloud, enabling you to launch and scale servers as needed.

Creating a Compute Instance

From the left-hand menu, click on the Instances tab.
To create an instance, click the plus (+) icon located on the right side of the page.

Choose a Location

Select the data center location where your server will be physically hosted.

Choose an Image

Select an OS or application template. Import a custom ISO if needed. For Microsoft Windows, only official evaluation versions are available.

Browse the full catalogs: OS Images and One-Click Apps.

Choose the Type of CPU Allocation

Shared CPU: Affordable, with resources shared among users. Ideal for development, testing, and low-performance workloads like small websites.
Dedicated CPU: Provides exclusive resources for consistent performance. Perfect for production environments, high-traffic applications, and databases.
High-Frequency Compute: Offers high clock speeds for compute-intensive tasks like simulations, financial modeling, and low-latency applications.
Cloud GPU: Delivers GPU acceleration for demanding tasks like machine learning, AI, video rendering, and scientific simulations.

Choose a Plan

General Compute (GC): Balanced workloads with a mix of CPU, memory, storage, and bandwidth. Ideal for general-purpose applications, web servers, and testing environments.
Compute Optimized (CO): Prioritizes CPU performance for compute-intensive tasks like batch processing, analytics, and high-speed processing workloads.
Memory Optimized (RO): Tailored for applications requiring high memory capacity, such as in-memory databases, big data processing, and real-time caching systems.
Database Optimized (DO): Specifically tuned for database workloads, offering enhanced I/O performance and memory-to-disk ratio for transactional or analytical database systems.

See Instance Types for families and storage tiers, and the pricing page for per-size specs and pricing.

Assign to a Project

Assign the server to one of your projects to organize resources.

Choose a Network

Public Network: A simple, pre-configured network for external connectivity. Includes cloud firewall protection, port forwarding, and remote access VPN.
VPC Network: A Virtual Private Cloud (VPC) offering complete control over traffic routing and enhanced security. Supports VPN gateway, site-to-site VPN connections, and traffic segregation.

Note: By default, a VPC is created with a random CIDR block and one network tier.

Choose whether to enable public IPv4.

Configure Server Settings

Add SSH Key for secure access. Click Add Now. For some OS images (e.g., Arch Linux) an SSH key is required.
Add a startup script to automate actions during initialization.

Advanced Settings (Optional)

Boot Mode: Select Legacy or Secure boot.
Boot Type: Choose between UEFI or BIOS.
Enable Dynamic Scaling: Allows automatic resource scaling.

Server Hostname

Provide a unique Server Name and valid Server Hostname.
