When you create a Tencent Cloud Lighthouse instance, the specified instance plan determines its configuration of CPU, memory, SSD CBS, bandwidth, and network traffic package. These instance plans consist of different combinations of CPU, memory, SSD CBS, bandwidth, and network traffic package. You can flexibly select a suitable plan for your application.
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. Instance Package
For more information on the supported Lighthouse instance packages and their pricing, please see Basic Package Pricing. Starter/General Type
The Starter and General type for Lighthouse offer a variety of cost-effective specifications. They are suitable for supporting lightweight, low-load, and moderately-trafficked application scenarios, such as small websites, Web applications, blogs, forums, and cloud-based development/testing/learning environments.
Razor Speed Bundle
Razor Speed Bundle Positioning
The Lighthouse Razor Speed Bundle provides 200 Mbps of public network peak bandwidth and imposes no limit on public network traffic usage. The public network peak bandwidth is optimized and scheduled through the resource pool to ensure a good user experience. This bundle is suitable for business scenarios with bursty, high-bandwidth demands, and is particularly well-suited for applications that are not sensitive to fluctuations in public network peak bandwidth.
Note:
The public network peak bandwidth in the Razor Speed Bundle represents the peak upper limit for both outbound and inbound public network bandwidth. It is not a service-level commitment. During peak business hours when resource contention occurs on Tencent Cloud, the public network bandwidth peak may be affected.
Application Scenario Recommendations for the Razor Speed Bundle
Scenarios
The Lighthouse Razor Speed Bundle is designed for lightweight, low-to-moderate load application scenarios such as websites, Web applications, mini-programs/mini-games, e-commerce applications, cloud storage/image hosting, and development/testing environments. When you have a demand for bursty, high peak bandwidth and are not sensitive to fluctuations in public network peak bandwidth, this bundle can meet your needs as much as possible under conditions of sufficient resources. Alternatively, during peak hours when resources are contended, it strives to ensure a good user experience through optimized scheduling of the resource pool.
Inapplicable Scenario
The Lighthouse Razor Speed Bundle is not suitable for scenarios that require a strong guarantee of public network peak bandwidth stability. If your business indeed has such requirements, such as for online meetings, remote work, video distribution, or large file transfers, we recommend that you choose the product combination of CVM and monthly bandwidth.
Note:
You are prohibited from deploying and running the following types of services on Lighthouse. For violators, we will take actions such as issuing alarms, suspending, and terminating services. Violations include, but are not limited to:
Do not deploy or run traffic tunneling or illegal proxy services using Lighthouse instances.
Do not deploy or run PCDN or other content delivery services using Lighthouse instances.
The instance system disks of all Lighthouse packages are Tencent Cloud SSD cloud disks, which are based on full NVMe SSD storage media and use a three-copy distributed storage mechanism to provide low-latency and high-throughput I/O capabilities with a high random IOPS and 99.9999999% data security. Their performance metrics are as follows: |
26,000 | Random IOPS = min{1800 + storage capacity (GB) * 30,26000} | 260 MB/s | Throughput = min{120 + storage capacity (GB) * 0.2,260} | 0.5–3 ms |
Public Network Bandwidth Cap Description
Outbound bandwidth cap description (downstream bandwidth)
Inbound bandwidth cap description (upstream bandwidth)
The cap of the package bandwidth used by a Lighthouse instance is the outbound bandwidth cap by default, i.e., the bandwidth that comes out of the Lighthouse instance.
Inbound public network bandwidth is the bandwidth that comes into a Lighthouse instance.
If the bandwidth of the purchased package is greater than 10 Mbps, Tencent Cloud will assign the instance an public network inbound bandwidth that is equal to the purchased bandwidth.
If the bandwidth of the purchased package is smaller than 10 Mbps, Tencent Cloud will assign the instance a public network inbound bandwidth of 10 Mbps.
Note:
The Lighthouse Razor Speed Bundle has a bandwidth cap of 200 Mbps for both outbound (downstream) and inbound (upstream) traffic.
When accessing Lighthouse instances in regions such as Hong Kong (China), Macao (China), and Taiwan (China), or in other countries/regions from Mainland China across borders, you may experience significant latency and packet loss due to carrier network routes. This typically does not occur during non-cross-border access.
Private Network Bandwidth Capability Description
Private network bandwidth capacity refers to the maximum amount of data (in bits) that can be transmitted per second between instances over the private network. This capacity is related to the instance plan.
Lighthouse instance plans with 8 or fewer CPU cores have a private network bandwidth capacity of at least 1.5 Gbps. Plans with 16 CPU cores have a private network bandwidth capacity of at least 2 Gbps. For specific instance plan configurations, see Basic Plan Pricing.
