For more information on the differences between Lighthouse and CVM, see Comparison with CVM.
An instance supports the overall upgrade of the configuration (computing, storage, and network) on a bundle basis but not bundle downgrade. For more information, see Upgrading Instance Bundle.
The quota of instances that can be created under each account is as shown below:Note
The instance quota refers to the maximum number of instances (including those to be repossessed) of a bundle type in a region under an account.
- In Singapore region, the quota of General bundles is 20 per account. Assume that you 2 General instances in this region, your remaining quota of General instances in this region will be 18.
- In Silicon Valley region, the Enterprise instance bundle has a default quota of 50 instances. If you already have 10 Enterprise instances in this region, your remaining quota of Enterprise instances in this region will be 40.
|Region||Instance Package Type||Quota (Instances/Region)|
|Hong Kong/Macao/Taiwan (China) and other countries/regions||General||20|
- Lighthouse instances divide into General and Enterprise bundles that come with different configurations. For more information on instance bundles, see Basic Bundle Overview.
- The General bundle can be upgraded to the Enterprise bundle. The upgraded instances will take up the quota of the target package.
There are certain limits on private network connectivity between Lighthouse and other Tencent Cloud services. For more information, see Region and Network Connectivity.
