Write in front
In the online world, no matter what new technology appears, the basic part will not change much. It is nothing more than dividing certain functions in certain places, or on the contrary, combining certain places in certain places. The functions are integrated and integrated, making them reunite and reunite.
It is precisely because the basic technologies have already taken shape that we need to master them more in-depth and solidly.
As long as we have a good grasp of the basics, no matter what technology and equipment are running at the upper level, we can deal with it calmly, and we will never get confused.
This article is written by a senior engineer. It is the first perfect combination of network and server. Starting from actual architecture experience, I will tell you the most down-to-earth technology. It uses 467 charts to explain the basic technology and design points:
Hardware composition, VLAN design, IP address design, security design, load balancing design, redundancy configuration virtualization, application management.

This article is accompanied by a picture to illustrate the basic technology and design points of the server-side network architecture in detail. Basic design is the most important stage of server-side network architecture. This article is based on the design subdivision projects of the basic design, and introduces the relevant technology and design points of each subdivision project in detail.
The full text is divided into 5 chapters, describing the technologies and design points necessary for physical design, logical design, security design, load balancing design, high availability design, and management design.
Chapter 1, Physical Design
This chapter mainly introduces the physical layer technology used on the server side, the design points when using this technology, and the general physical structure type.
On the server side, the only objects we can see are racks, cables, ports and other physical things. For this reason, we must fully understand their technologies and specifications and make designs that meet customer needs. The strict design in the physical layer will deeply affect the future scalability and operational management of the system.
Chapter 2, Logic Design
This chapter mainly introduces the technologies used in the data link layer and network layer of the server, as well as the design points when using these technologies.
In recent years, the basic technology related to the network has not made great progress, but it has become more pure and concise. However, blade servers and virtualization technologies used in servers and clients are advancing with each passing day, and the network forms that people pursue are also constantly changing. We must understand these technologies and specifications well, and design a logical structure that best meets the needs of customers to flexibly respond to these changes.
Chapter 3, Data Security Design and Load Balancing Design
This chapter will explain the server-side technology from the transport layer to the application layer and the design points when using these technologies.
Almost all the applications we use or develop can be "circulated" and run on the network, so the information flow is also increasing rapidly. For these surges of information traffic, how much security the server can provide, and how much processing can be completed, these two points can be said to be the key to the server. Only by solidly mastering the technical specifications and designing the best information security environment and load balancing environment can we flexibly respond to more and more information flows and increasingly complex application requirements.
Chapter 4, High Availability Design
This chapter will introduce the redundancy technology necessary to improve server-side availability, the design points when using the technology, and the communication flow in various structure types.
Availability refers to the degree of system failures and failures. Redundant configuration refers to multiple backups of the system to ensure high availability. At present, it can be said that all mission-critical systems are on the network. In such an environment, even one minute or one second of system downtime is fatal. It takes a lot of time to build a trusting relationship from scratch, and it only takes a blink of an eye to lose it. Therefore, we must design a reasonable and sufficient redundancy structure to achieve high availability, so as to avoid losing the trust of customers.
Chapter 5, Management Design
This chapter will explain the technology used in server-side operation management and its design points, as well as some matters that we should prescribe well in advance for operation management.
Various problems often occur on the mission-critical server side. After the design and architecture are over, the server can really begin to perform its mission. In the course of long-term use, the device may malfunction and the cable may be disconnected. For these different types of problems, we must not only pay attention to detection and prevention, but also be able to quickly take countermeasures in emergencies. To this end, we must be proficient in relevant technologies and equipment specifications, and design an operation management environment that best meets the actual situation.

Who should read this article
1. Network engineers who want to design the server side
Engineers who have mastered downstream engineering such as architecture and testing will transfer and develop to upstream engineering such as requirement definition and basic design. In the network architecture, the basic design is the lifeline, and the rules made in the basic design determine everything on the server side.
This article describes the most basic content that should be determined in the basic design in each chapter, and I believe it can help you in the basic design.
2. Server engineers who want to understand the network
Nowadays, technologies such as virtualization and network storage have become an indispensable part of the system. Most of these technologies use a network-based framework. We can already say that servers and networks are inseparable. For those engineers who say "I am good at servers, but I don't understand the network...", this article uses a lot of illustrations to explain, which will definitely make you like network technology. .
3. On-site management personnel responsible for server-side operation and management
In the long-term on-site operation, managers will encounter various problems, such as server service errors, network equipment damage, and so on. There is only one shortcut to solve the problem, and that is to learn the basic techniques. The server side is a world spliced by many basic technologies. This article lists some architectural examples that can help you master each basic technology and finally splice a complete world.
