General Restrictions
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. Quota Limits
Different Lighthouse instance bundles have different quotas of purchasable instances.
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.
For example:
In Singapore region, the quota of Razor Speed bundles is 5 per account. Assume that you 2 Razor Speed instances in this region, your remaining quota of Razor Speed instances in this region will be 3.
The quota of instances that can be created under each account is as shown below:
|
Hong Kong/Macao/Taiwan (China) and other countries/regions | Razor Speed | 5 |
| Starter | 20 |
| General | 20 |
Note:
Lighthouse instances divide into Razor Speed, Starter and General bundles that come with different configurations. For more information on instance bundles, see Basic Bundle Overview. You can upgrade an instance between the Starter and General bundles. After a successful upgrade, the instance will be counted against the quota of the target plan type.
When upgrading the Razor Speed Bundle for an instance, you can only select another Razor Speed Bundle with higher specifications.
If the quota for Starter or General instance plans (excluding the Hong Kong (China) region) is insufficient for your needs, please contact us to apply for a quota increase. Tencent Cloud will evaluate your application based on the reasons provided. Once approved, you can enjoy the corresponding purchase quota. Up to 100 firewall rules can be created for each Lighthouse instance.
Up to 10 SSH key pairs can be created in each region under one account.
Up to 20 custom images can be created in each region.
Snapshot quota limits: The maximum number of free snapshots in each region is the number of created instances multiplied by 2 and cannot exceed 10.
Private Network Connectivity Limits
There are certain limits on private network connectivity between Lighthouse and other Tencent Cloud services. For more information, see Region and Network Connectivity.
