Tencent Cloud Distributor: How to Use EdgeOne to Achieve "Safe and Accelerated" Dimension Reduction Strike under the Peak of Big Traffic Promotion

During business peaks or promotional activities, the technical team is often faced with an extreme test of "both and:

Both… and…

The web page opens quickly and the interface responds in milliseconds, allowing users around the world to place orders smoothly;

Again

Strictly guard against hacker's DDoS flood peak, wool party's highly concurrent malicious bill brushing, and various SQL injections for the application layer (Layer 7).

In the past, this is almost a "fish and bear's paw can not have both" paradox. In the traditional architecture, we either hang a bunch of CDN nodes at the front end to speed up and expose the source station to risks. Either a pile of hardware or cloud WAF is connected in series behind the CDN to clean the traffic, resulting in an increase in the number of network hops (Hop), a full delay, and users doubt their lives when checking out.

Until Tencent Cloud launched a new generation of edge security acceleration platform--

EdgeOne (TEONE)

This embarrassing situation was completely broken. In today's tutorial, I will not talk about the concept of virtual, but directly disassemble how to use EdgeOne to fill up "global acceleration" and "WAF protection" on the edge side at the same time from the perspective of actual combat architecture ".

Why does 1. traditional "decoupling architecture" inevitably pull across when promoting?

Before we get down to business, let's review the "hard wounds" of the traditional architecture ". In the past, we used to use the "CDN independent WAF source station" routine.

Plaintext

[User]-> [CDN Edge Node (Acceleration Only)]-> [Centralized WAF Cleaning]-> [Origin Server]

When this architecture is promoted, it will expose three fatal problems:

The "overlapping music" of network delay: the traffic goes to the CDN node first, finds that there is no cache, and passes through WAF first when returning to the source. WAF unpacks, detects and cleans before transferring to the source station. This time, the precious millisecond time was wasted on link transmission and multiple decryption.

The "time difference" of security policy: the attack of the big promotion is changing rapidly. When O & M detects a CC attack in the security console and adjusts the policy, because acceleration and security are two systems, there is often a delay of several minutes when the policy is synchronized to the global node. These few minutes are enough for the source station to crash several times.

The "bottomless pit" of cost: In order to prevent the big promotion from being collapsed by D, enterprises have to purchase high-security IP and WAF instances according to the "estimated maximum attack peak. After the big push, these high fixed assets are directly idle, and the boss looks absolutely ugly when he looks at the bill.

The underlying logic of 2. EdgeOne: completing "All in One" at the edge"

The disruptive nature of Tencent's cloud EdgeOne core is that it puts

High-performance acceleration, DDoS protection, Web protection (WAF), Bot behavior analysis

It all sinks to the edge of the world.

Simply put, the past was "acceleration at the edge, security at the core";

Speed and safety, side by side on the edge ".

When a request arrives at EdgeOne node, the node kernel completes WAF semantic parsing and threat intelligence comparison in parallel while processing cache distribution (seven-layer forwarding).

Security detection becomes an "embedded link" in the forwarding process, achieving true security "zero" additional delay.

3. Combat Exercise: A Four-Step Configuration Method for Promoting Defense and Acceleration

In order to make everyone's business stable in the next big promotion, it is recommended to configure the EdgeOne in depth according to the following steps:

The first step: dynamic and static separation, fine configuration edge cache

The home page, product details page, activity banner, etc. of the big promotion are typical static resources.

In the Rules Engine of the EdgeOne console, set up a long cache (for example, 7 days) for images, CSS, JS, and HTML pages.

Enable "browser cache" and "node cache" dual optimization. In this way, up to 90% of the requests are returned directly to the nearest edge node without touching the source station at all.

Step 2: Turn on full-site acceleration (WSA) and intelligent back-to-source for dynamic interfaces

Order (

/api/order/create

), shopping cart (

/api/cart/add

) is purely dynamic and cannot be cached.

Turn on full-site accelerated optimization for these dynamic routes in the EdgeOne.

EdgeOne will use Tencent's global backbone network to automatically avoid congested nodes in the public network through real-time detection (detection of packet loss rate and delay), and plan a "green and smooth waterway" back to the source for dynamic requests to ensure that global payments are completed in seconds.

Step 3: Activate WAF Intelligent Defense and Semantic Analysis

Hackers often use complex deformation scripts for SQL injection. Traditional rule matching (based on regularization) can easily be bypassed or produce a large number of "manslaughter" (keeping out normal snapping users).

In the EdgeOne security configuration, select AI Semantic Analysis Engine ". It looks not only at the signature, but also at the context logic.

For the core transaction interface, the WAF policy is set to "intercept" mode, and adaptive anti-scanning is turned on. As long as an IP is found to be frantically detecting the background interface, it is directly blocked at the edge.

Step 4: Configure advanced Bot behavior management to prevent the wool party

Coupons and seconds-killing goods that are greatly promoted are often ransacked by "script black products" in an instant.

Open Bot behavior analysis in the EdgeOne. It accurately distinguishes "whether a real person is running a crazy hand point" or "a robot is running a script" by collecting multi-dimensional data such as browser fingerprints, mouse trajectories, request rates, etc ".

For requests for suspected bots, configure the "verification code (Captcha)" challenge or directly "discard", leaving valuable goods to real consumers.

4. Pit-Avoidance Guide: The "Non-Technical" Key Closed Loop of Great Promotion Preparation

As an architect, I 've seen too

The multi-technical solution was done perfectly, but it was a case of "non-technical factors" that caused a big rollover. For example, large-scale traffic promotion exceeds expectations, resulting in cloud arrears downtime, and temporary modification of configuration cards in the approval process.

When preparing to access Tencent cloud EdgeOne, there are several "pragmatic channels" related to efficiency and financial security that need to be planned in advance:

Compliance starts, and the first step before choosing the right starting point is often to sort out the assets. When an enterprise purchases a Tengxun cloud account, it must go through a regular channel that supports enterprise-level real-name authentication. A high-authority, qualified and compliant business owner's account is the underlying guarantee for subsequent applications to EdgeOne global high-security resources and open a dedicated green channel for big promotion.

With the help of external brains, save money and effort. If your technical team has limited manpower or is not sure about the configuration of edge safety rules, it is recommended to contact a professional

Tencent Cloud Agent

. Not only can agents offer more flexible, fracture-level business discounts based on the size of the business, but more importantly, they usually bring their own team of senior cloud architects. On the eve of the promotion, the agent's technical experts can assist in the architecture review and even provide 7x 24-hour escort during the promotion.

The CDN bandwidth and flexible WAF consumption during the period of the risk of downtime are exploding. If the financial approval process is lengthy, the entire foreign trade station or e-commerce App will often be shut down due to the arrears of several hundred dollars. Through the agent to carry out Tencent cloud on behalf of the recharge, enterprises can obtain more flexible account period credit and emergency advance support, to ensure that in the traffic tsunami, the rear capital chain is stable, the business is absolutely line.

Conclusion

The evolution of technical architecture is essentially for business growth. Tengxun Cloud EdgeOne's All in One architecture, which deeply integrates "global acceleration" and "extreme security", is becoming the standard configuration for the new generation of Internet to go to sea and e-commerce.

Solve the speed problem on the edge side and nip the danger in the bud on the edge side. With good EdgeOne and the professional support of Tengxunyun's ecological partners, your technical team will be able to sit firmly in Diaoyutai in this big flood promotion peak.
