Regions
A region refers to a region where Tencent Cloud hosted data centers locate. It contains multiple availability zones (AZ).
For example, a hosted data center's region is Singapore, and its AZ is Singapore Zone 1. Cloud service products within the same region can communicate via the private network, while products across different regions cannot. To reduce access latency and improve download speed, select the region closest to your customers.
Availability Zones
An AZ refers to a physical data center within the same region where Tencent Cloud's power and network infrastructure are independent of each other. This design aims to ensure that faults are isolated between AZs and do not propagate, thereby keeping users' services continuously online.
Tencent Cloud Lighthouse
Tencent Cloud Lighthouse(Lighthouse) is a CVM that is easy to use and manage, and is suitable for hosting lightweight business workloads. It helps individuals and enterprises quickly build various applications such as websites, blogs, e-commerce sites, and forums, as well as development and test environments in the cloud. Lighthouse provides a one-stop, full-process service for application deployment, configuration, and management, significantly improving the experience of building applications. It is the best entry point for you to use Tencent Cloud.
Tencent Cloud Lighthouse Instances
Similar to the concept of a CVM instance, a Lighthouse instance can also be understood as a server, which includes the most fundamental components such as CPU, operating system, network, and disks. Lighthouse instances are typically suitable for supporting lightweight, low-load application scenarios such as small websites, Web applications, and cloud-based learning.
Instance Package
When you create a Tencent Cloud Lighthouse instance, the instance bundle you specify determines its configuration, including CPU, memory, SSD CBS, bandwidth, and network traffic package. These instance bundles consist of different combinations of CPU, memory, SSD CBS, bandwidth, and network traffic package. You can flexibly select a suitable bundle for your application.
IP Address
An IP address is a unified address format provided by the IP protocol. It assigns a logical address to every network and host on the Internet, thereby masking the differences in physical addresses. In this context, it refers to the service addresses of an instance for internal and external communication, namely the private IP address and the public IP address.
Public IP Address
A public IP address is accessible over the Internet and can be used for communication between an instance and the Internet, or between an instance and other Tencent Cloud resources that have public endpoints, such as database resources.
Private IP Address
A private IP address (Private IP) refers to an IP address assigned to an instance within a Tencent Cloud VPC or the basic network. A private IP address cannot be accessed over the Internet, but it can be used for communication between instances within a VPC or the basic network.
Images
An image is a pre-configured template for launching and running a Lighthouse instance, which includes a pre-installed operating system and software. In simple terms, you can think of an image as the "installation disk" for a Lighthouse instance. You can use an image to create one or more Lighthouse instances.
Cloud Disks
Cloud Block Storage (CBS) is a highly available, reliable, cost-effective, and customizable block storage device that provides efficient and reliable storage for Lighthouse instances. CBS offers block-level persistent storage and is typically used as the primary storage for data that requires frequent, fine-grained updates (such as file systems and databases). It features high availability, reliability, and performance. CBS employs a distributed three-replica mechanism to back up your data across different physical servers, preventing data loss caused by single points of failure and enhancing data reliability.
Tencent Cloud Lighthouse Firewall
Tencent Cloud Lighthouse firewall is a crucial tool for ensuring the network security of Lighthouse instances. You can enable specific ports on an instance by configuring firewall rules.
