When you create a Lighthouse instance, the instance package you specify determines its server hardware configuration. The computing, memory, and storage features vary by instance package. You can select an appropriate instance package based on the scale of your application to be deployed. These instance packages consist of different combinations of CPU, memory, SSD cloud disk, and network traffic package, so you can flexibly select appropriate resources for your applications.

Instance Limits

• The total number of instances that can be started in a region is limited. For more information, please see Use Limits.
• The purchasable instance packages may vary by region, and some packages may be sold out. The information displayed on the actual purchase page shall prevail.
• Please pay attention to the corresponding network traffic package capacity (i.e., upper limit) of each instance package. After the network traffic of a Lighthouse instance exceeds the limit, it will be billed by the general network bandwidth traffic. For more information, please see Billing Overview.

Note：

• When creating a Lighthouse instance, you cannot specify the CPU model of the underlying physical server; instead, Tencent Cloud will randomly assign a physical CPU model that meets the selected package specification.
• At the same specification level, Lighthouse has a CPU and memory performance comparable with that of CVM.
