Tencent Cloud Lighthouse (Lighthouse) is a new-gen cloud server service for small- and medium-sized enterprises (SMEs) and individual developers. It features out-of-the-box service for cloud-based lightweight business scenarios, such as websites, web applications, mini programs, mini games, apps, cloud storage, image hosting, and various development and testing environments.

Compared with CVM, Lighthouse is easier to use and more suitable for SMEs, developers, cloud computing beginners, and students, as it simplifies CVM's advanced concepts and features. It integrates basic cloud resources into cost-effective out-of-the-box bundles. Such bundles contain popular open-source software programs perfect for lightweight use cases with low to medium load and moderate access requests, such as small websites, web applications, blogs, forums, mini programs, and mini games, as well as development, testing, and learning environments in the cloud. For more information, see Product Comparison.

For more information on Lighthouse and how to quickly get started with it, see the following documents:

• Creating Application with Lighthouse
• Creating Lighthouse Instance

The bundle (computing, storage, and network) of a Lighthouse instance can only be upgraded, but not downgraded.

The VPC of a Lighthouse instance cannot be specified by the user. It’s assigned automatically by the system.

For more usage limits, see Use Limits.

You can copy local files to a Lighthouse instance or download the files on it to your local file system. For more information, see How do I copy a local file to a Lighthouse instance?.

Lighthouse is billed in a prepaid (monthly subscription) manner. The bundle validity ranges from 1 month to 5 years. If the instance is terminated before the expiration time, you will get a refund for the remaining validity. For more information, see Refund.

No. The basic bundle you select at the time of purchase already includes a data transfer plan. If the plan quota is run out, the out-of-plan data transfer is billed on a pay-as-you-go basis. For more information on the basic bundle and out-of-plan data transfer, see Billing Overview.

Out-of-plan data transfer is billed by the outbound traffic, i.e., total volume of data transferred over the public network in GB. For more information, see Excessive Traffic Pricing.

By default, each account can create ten Lighthouse instances per region. If you need a higher quota,submit a ticket .

You can refer to Best Practices to set up low-load lightweight applications with a moderate number of access requests, such as small and middle-sized websites, web applications, blogs, forums, mini programs, mini games, ecommerce, cloud storage, image hosting, and cloud-based development, testing, and learning environments.

You can quickly and easily create and deploy applications with the application images offered by Lighthouse. For more information, see Quickly Creating Application with Lighthouse.For currently supported images, see Application Image.

Tencent Cloud regions are completely isolated. This guarantees the maximum cross-region stability and fault tolerance. We will gradually deploy nodes in more regions for a wider coverage. We recommend you select the region closest to your end users to minimize the access latency and improve the download speed.

Lighthouse is currently available in the following regions:

• Hong Kong (China), Singapore, Tokyo, Silicon Valley, Toronto, Frankfurt and Mumbai.

Select the region closest to your target users to reduce the network access latency. For more information, see Region and Network Connectivity.

Lighthouse instances in the same region under the same account can be interconnected over the private network by default, while instances in different regions cannot. For more information, see Private network connectivity description.

By default, Lighthouse instances cannot interconnect with other Tencent Cloud resources in VPCs such as CVM and TencentDB over the private network, and their interconnection needs to be implemented by associating a CCN instance. For more information, see Interconnection over Private Network.

Data transfer of a Lighthouse instance is included in the bundle. The quota of data transfer refers to the monthly upper limit on the public network outbound traffic. Out-of-plan data transfer is billed on the pay-as-you-go basis. For more information, see Billing Overview.

You can achieve convenient and efficient data protection by creating snapshots. Lighthouse offers a free tier of snapshots. For more information, see Managing Snapshots.

A Lighthouse image is a template for launching and running a Lighthouse instance. You can use an image to create one or multiple instances. Lighthouse provides images on multiple operating systems such as Linux and Windows Server as well as images of applications such as LAMP and WordPress.

• Application image: An application image provides everything you need to launch a Lighthouse instance, including the OS, applications (such as LAMP, WordPress, ASP.NET and Node.js), their runtime environments, and relevant initialization configuration files.
• System image: A system image is a public image similar to CVM and supports OS images of various Linux distributions (such as TencentOS, CentOS, Ubuntu, and Debian) and Windows Server.
• Custom image: Images created by the user. Custom images can only be used by the creator.

Yes. Cloud Workload Protection Platform (CWPP) Basic are activated by default for Lighthouse instances to help you build a server security protection system.

A firewall is an important method to protect the Lighthouse instance's network security. Its security protection features are equivalent to security groups in CVM. You can configure firewall rules to allow or reject access to Lighthouse instances over the private or public network. For more information, see Managing Firewall.

Yes. You can set threshold alarms for the performance metrics of Lighthouse resources supported by Cloud Monitor (CM) , so that when an exception occurs, you can promptly receive notifications by email, SMS, or phone call and take actions.

Yes. Lighthouse is connected to Cloud Access Management (CAM) and supports resource-level authorization. CAM can help you control the access permissions, resources, and use permissions of your Tencent Cloud account. For more information, see CAM Overview.

Yes. You can view CloudAudit operation records in the following steps:

1. Log in to the CloudAudit console and select 【Event History】.

2. Select “LIGHTHOUSE” as the “Resource Event Name” and click 【Query】to view the CloudAudit operation records.
