Today, what the editor shares with you is the importance of a stable network environment and server database architecture design, which many people do not quite understand. Today, in order to let you know more about the server database architecture design, the editor summed up the following contents. Let's move on. I'm sure you'll get something.

With the development of Internet and mobile Internet information technology, and the increasing improvement of social attributes, the application of Wechat in the event scene has been explosive growth, capturing the psychological needs of on-site users, effectively promoting and improving the traditional sense of meetings, exhibitions and other marketing activities and user stickiness, and even improving the conversion rate of their own products.

At present, the more meetings, exhibitions and event venues, the more WeChat walls (3D WeChat walls), Wechat Shake, Wechat Shake Awards, Wechat Shake Red packets, Wechat lucky draw and other forms of live interaction combined with Wechat. Attendees interact with the big screen (LED screen or projection) through Wechat, and the results of the interaction on the mobile side will be directly or indirectly reflected on the big screen, which makes it more participatory and interesting. Through such an interactive system, conference organizers can easily achieve powder absorption (an important part of Wechat marketing) and enhance the effect of the exhibition, which can be described as the ultimate weapon of on-site interaction.

A complete on-site interaction system, which is composed of front-end display module, activity setting module, mobile interaction module, administrator management module and data analysis module, is a complex system, and there are many technical means involved.

The stability of the interactive system to ensure the stability of the interactive platform is a very important consideration in the whole event, especially in large-scale meetings and events, the stability of the platform is very important. Usually about 500 people shake Wechat (if the pressure on the server and database will be more prominent in order to grab the red packet), when there is active interaction on the spot, it may exert some pressure on the server. This will also be paid special attention to in the design of the whole system.

If you want a good on-site interaction effect of an event, in addition to having a professional service team and selecting a reliable technical service platform, there is an extremely important factor that even determines the success or failure of the interactive link, that is, the network environment of the event site. Often, the reason for our failure lies in the network environment on the spot!

There are two aspects to this network environment:

(1) the technical side that provides interactive services needs to have a stable, dedicated network with sufficient bandwidth, and often many places are difficult to solve their own reasons or cost problems, resulting in high data requests on the spot, but due to the lack of network bandwidth, the data channel is congested, data processing is not timely, stutter, or even the effect is not fully loaded, the picture is lost, resulting in an error report.

Under the premise that the program stability is already reliable and has been verified by the market, the methods to improve the stability of the system can be as follows:

① expands the hardware. Expanding hardware is a relatively simple method, and the pressure is shared to each server through load balancing. According to the experience summary of professional technical team and thousands of activities, the interactive marketing operation service management platform of domestic well-known "Wechat +" activity scene adopts the architecture scheme of "multiple computing servers load balance + database RDS" to ensure the on-site interaction effect of regular activities.

② program optimization. Program optimization using various buffering and queuing mechanisms is an important part of improving system stability, and the implementation of a reasonable and effective optimization measure is very important to the improvement of the system. In the single-server version, reasonable optimization can fully support all the needs of small meetings, exhibitions, and planning companies.

③ customization scheme. Usually, the on-site interactive system platform provides users with interfaces such as changing background pictures and background music, which is sufficient for general application scenarios, for super-large-scale live interaction activities. How to deal with more complex customization requirements? The answer is that there is no way to modify the source code according to the actual situation to make special customization, and cooperate with the implementation of the exclusive server group and database architecture scheme. Technically speaking, it is possible for users to completely customize the form of expression in the front section, but this involves the architecture and overall security of the whole system. At this time, it is not just a question of cost. It is also the time to test the technical strength of the chosen technology executor.

(2) the speed of the WIFI network at the scene is low and unstable, or even the network is cut off or the mobile network signal of the users on the site is very poor.

The signal effect of the mobile network is related to the number of users used, and the user scale of a base station service is limited. At large-scale events, due to the large number of Internet users at the same time, it is easy to have network congestion. The possible causes of this problem are:

① did not install emergency communication equipment outside the site.

The indoor network signal condition can be improved by increasing the outdoor signal. Install a repeater or emergency communication vehicle near the site where there is an indoor blind area, or increase the transmission power of the base station covering the place, so as to strengthen the outdoor signal strength and make use of the penetration ability of electromagnetic waves to solve the problem of indoor signal coverage.

For some places where the network is not perfect, on the one hand, it solves the problem of indoor coverage, on the other hand, it also solves the signal coverage and traffic absorption in the surrounding areas, killing two birds with one stone. In terms of specific operation, the provider of the conference venue can apply to the three basic telecom operators to provide corresponding emergency communication services. Take a conference as an example, as senior executives of the Ministry of Industry and Information Technology and telecom operators will make speeches, so the three major operators attach great importance to emergency communications, the corresponding indoor signal is better.

② did not do a good job of indoor signal depth coverage.

To really solve this problem, we still need to cover the indoor signal deeply. For example, small base stations are arranged indoors. The principle of indoor signal coverage is to use the indoor antenna distribution system to evenly distribute the signals of the mobile base station in every corner of the room, so as to ensure that the indoor area has ideal signal coverage.

There are generally three ways to achieve indoor signal coverage: micro-cellular wired access, macro-cellular wireless access and repeater. In the specific operation, it is necessary for the site provider to cooperate with the telecom operator or network equipment provider by arranging the corresponding communication equipment to achieve.

The key to solving the core problem of ③ lies in the site provider.

The organizer of the event cannot solve this problem directly and needs to be done through the venue provider. It is difficult to solve this problem, and the key is that the provider of the site does not pay enough attention to it. At the same time, there are some obstacles at the technical level.

In public places such as large conference rooms and exhibition centers, site providers are often in a dilemma when multiple users need to access the network at the same time. Either cross-place multiple AP (wireless access access points) and need to reduce the power to avoid interference, or inform users that the capacity of the AP with different identifiers is limited and require zonal access, or simply "dare" to open the wireless environment, or the user "actively" gives up because of the slow and abnormal network experience.

To solve the problem of indoor signal coverage, it can not be solved by arranging a few AP. With multiple AP, bandwidth can quickly be reduced to almost unavailable due to competition between AP. Moreover, only three non-overlapping channels in the 2.4GHz band can be used, so the three channels need to be covered as non-overlapping as possible. If not, we need to consider using sector antennas to subdivide the coverage area into several sectors.

In high-density WLAN management, you also need to manually specify AP for users to prevent some AP from being overloaded. At the same time, appropriate AP needs to be assigned to different terminals according to the signal strength of the client, because if the signal of some devices is too weak, the low rate will slow down the overall AP performance.

So it seems to be a simple problem, but in fact it is not that easy to solve. However, as long as users have this demand, the event organizers will gradually regard the coverage effect of the network signal as an important criterion for selecting the site, thus driving the site provider to solve this problem effectively.

The importance of stable network environment and server database architecture design I believe you can see here that we have a certain understanding of the concept, characteristics and working principle of the server. If you think this article is helpful to you, you might as well share it for more people to see.
