We need DNS (Domain Name System) to translate human-readable domain names (like www.example.com) into IP addresses (like 192.0.2.1) that computers use to identify each other on the network. It's like a phonebook for the internet, allowing users to access websites using easy-to-remember names instead of numerical IP addresses.
For example, when you type www.example.com into your web browser, your computer sends a request to a DNS server to find the corresponding IP address. The DNS server responds with the IP address, and your browser can then connect to the website.
In the context of cloud computing, DNS plays a crucial role in routing traffic to cloud services. For instance, if you're using a cloud hosting service, DNS helps to direct users' requests to the correct servers hosted in the cloud.
For reliable and efficient DNS services, you might consider using Tencent Cloud's DNSPod, which offers high availability, low latency, and robust security features to ensure your domain name resolution is always up-to-date and accurate.
