-Scaleway Instances are virtual machines in the cloud. You can create and manage Instances via our [console](https://console.scaleway.com/), [API](https://www.scaleway.com/en/developers/api/), [CLI](https://www.scaleway.com/en/cli/), or [other developer tools](https://www.scaleway.com/en/developers/). When you [create an Instance](/instances/how-to/create-an-instance/), you must select the **Instance type** you want to create. This page explains the different ranges of Instances available at Scaleway and helps you to choose the best one for your needs.

 * **vCPU**: A **v**irtual **C**entralized **P**rocessing **U**nit represents a part of the underlying physical CPU that is assigned to a particular Instance.
 
-    vCPU may be **shared** or **dedicated**.
+    Each vCPU may be [shared or dedicated](/docs/instances/reference-content/choosing-shared-vs-dedicated-cpus/).
         - **Shared**: A [context-switching mechanism](https://en.wikipedia.org/wiki/Context_switch) allows a physical core to be shared between multiple vCPUs for multitasking. Instances with shared vCPU can be more cost-effective for running small, non-resource-intensive applications than dedicated vCPU Instances. Our different types of shared vCPU Instances offer a variety of options to balance price and performance depending on your use case.
         - **Dedicated**: Instances with dedicated vCPU do not share their compute resources with other Instances (1 vCPU = 1 CPU thread dedicated to that Instance). This type of Instance is particularly recommended for running production-grade compute-intensive applications.

-          Scaleway provides Instances equipped with either x86 or ARM CPUs. ARM Instances generally offer higher energy and cost efficiency, while x86 cloud Instances provide wider software compatibility and stronger single-thread performance.

 * **Core**: A core is a physical unit of vCPU. More cores give an Instance more computing power. A description of an Instance's cores may look something like `4 x86 64bit`, where **4** refers to the number of cores, **x86** refers to the microprocessor family, and **64bit** refers to the chunk size used by the microprocessor for processing data.
