Models, Zones & Operating System

Zenlayer virtual machines have three kinds of models with different configurations. The table below displays the main parameters as reference.

Models

Four types of specifications are supported:
  • Compute-optimized (Dedicated vCPU) Compute-optimized instances typically have a higher vCPU-to-memory ratio, such as 1 vCPU to 2 GB of RAM, making them well-suited for compute-intensive workloads.
  • General-purpose (Dedicated vCPU) General-purpose instances have a 1:4 vCPU-to-memory ratio, making them ideal for various workloads, including web servers, small databases, and development environments, that require moderate compute and memory resources.
  • Memory-optimized (Dedicated vCPU) Memory-optimized instances have a higher memory-to-vCPU ratio, such as 8GB of RAM per CPU, making them well-suited for memory-intensive workloads that require large amounts of memory, such as database management and high-performance computing.
  • Basic compute (Shared vCPU) Basic compute instances offer shared vCPU resources, making them a cost-effective option for running basic workloads that don't require a lot of computing power or memory, such as simple web applications and lightweight development environments.
The available types are shown in the following table.

Note
  • c refers to vCPU and g refers to memory. For example, Compute-optimized 1c2g (c.1c2g) refers to 1 vCPU cores and 2 GB memory; General-purpose 2c8g (g.2c8g) refers to 1 vCPU cores and 2 GB memory.
  • The available models in each location vary depending on the inventory.

Available Locations

Virtual Machine instances are deployed by locations. Each location has its own power grid and network structure. Your instances in the same location can buildup private network by VPC.
