architecture Design high concurrent ultimate solution or the latter: horizontal expansion. In the Internet layered architecture, the practice of horizontally expanding at different levels is different: (1) The reverse proxy layer can be extended horizontally through the way of "DNS polling"; (2) The site layer can be expanded horizontally through nginx; (3) The service layer can be expanded horizontally th

What is DDNS? I. Introduction to DDNS The DNS and domain name system are a service of the Internet. As a distributed database that maps domain names and IP addresses to each other, it makes it easier for people to access the Internet. DDNS, a dynamic domain name system, is a technology that automatically updates the

With the development of the Internet, users pay more attention to the browsing speed and effect of the website when they use the network, but because of the increasing number of netizens, the network access path is too long, so that the quality of users ' access is seriously affected. Especially when the link between the user and the website is congested with lar

appropriate for them. To achieve this, it assigns an IP address to each Pod.Kubernetes provides a Service abstraction that provides a stable IP address and DNS name to correspond to a dynamic set of pods, such as a set of pods that make up a microservices. This pod group is defined by the Label selector, because any pod group can be specified. When a container running in the Kubernetes Pod

What is DHCP Snooping? This problem may not be very clear to many friends. Here we will give a brief explanation of this problem. DHCP Pnooping is a DHCP snoop. It monitors users through DHCP interaction packets between the Client and the server, and DHCP Snooping provides a DHCP packet filtering function, filter illegal servers with proper configuration. The fol

required, but we recommend that you add it. This method does not stop when an error occurs and a fatal error occurs. And give developers the opportunity to capture any errors (when a PDOException exception is thrown ). The setAttribute () line is mandatory. it tells PDO to disable the simulation of the pre-definition statement and use the real pre-definition statement. This ensures that the statements and

, improving network flexibility and availability. Server Load balancer has two meanings: first, a large amount of concurrent access or data traffic is distributed to multiple node devices for separate processing, reducing the user's waiting for response time. Second, computing of a single heavy load is distributed to multiple nodesPoint devices perform parallel processing. After each node device finishes pr

After the vswitch system is restarted successfully and the VRP platform software is updated, the switch system is reconfigured according to the previous configuration, and the switch's working status returns to normal immediately, so what is the reason? As a core network ter

As you know, there are usually no fixed IP addresses when dialing the internet. In addition, after the dial-up goes online, we don't need to worry about IP addresses, gateways, and DNS, because these are all set by the Telecommunications Bureau. After going online, I got an IP address. After we got disconnected, the address was reclaimed by China Telecom and provided to others. This is very similar to DHCP.

What is the difference between the bridge mode and the NAT mode? Bridged networking (Bridging Mode)In this mode, the Virtual Operating System of VMWare is like an independent host in the LAN, which can access any machine in the network.
