Why does the website fall? Just a lot of people. Where is it wrong?

The fact that many people enter the website It's not wrong. But it is our goal too! But the real problem is hidden in the "behind the scenes". Imagine Every time someone clicks on your website Their computers will send your request to your "Origin Server", which is like a web warehouse, including text, images, pictures, code, server, must process and send all this information back to users one by one.

Now ... If 10 people come in at the same time, the server is 10,000 people. If coming in at the same time, the server must work 10,000 at the same time! The server resources (both CPU, RAM) are limited. When working is too hard to work It is like a person who runs the marathon. In the end, it was exhausted and fell. That is why your website is sluggish and finally crashed. There is no "resting mechanism" or "shortcut" for the server. Is the source of all problems

If allowing the website to be slow-often fall How serious will it affect?

Slow web or web problems often fall. Not just an annoying technical matter But it directly affects your business in an unexpected way. This is what happens when you leave this problem:

• Lost sales immediately: Customers who intend to buy things Can't press to pay He just close the window and buy from your competitors instead. The opportunity lost in that minute May not come back again
• Destroy the user experience (User Experience): No one likes to wait. Websites that load more than 3-5 seconds make people irritated and see your brand. "Non -professional" The first impression is negative. The less opportunities to come back to buy.
• Break the brand's reputation: when a big problem occurs at a famous campaign People will continue to speak on social media negatively. Become a crisis in the image that must be resolved for a long time
• Affecting SEO: Google is very important to the speed of the website (Core Web Vitals). The website is slow and often crashed. Will be reduced to search continuously Make new customers Looking for you to get up
• Waste marketing budget: advertising fees you paid for people to click in Became zero as soon as they found an unusable website It is truly a budget. Which is a great concern for large businesses that may consider using a solution like Webflow Enterprise for businesses that need stability.

What is the solution? Get to know "Website Caching Strategy", the real hero.

The solution of this problem is to lay the strategy of "Cache" (Cache) that is smart. Catching is "Creating a copy" of your website information at various points. Closer to the user than the main server So that when people come to see the web He will receive information from the "copy" that is loaded faster instead of having to run from the main server every time. Is to reduce the workload of the server enormous

In general, Caching strategy is divided into 3 main levels that work together:

• 1. Browser Cache (Cash on the device): Ordering the web browser (Chrome, Firefox, Safari) of the user "remember" files that are unchanged, such as logo, CSS, JavaScript files, when users return to the web again. Then do not need to download these new files Causing the 2nd visit onwards
• 2. CDN Cache (Content Delivery Network): This is the heart for the website with high traffic. CDN is a server that is distributed around the world. It will "suck" your website to keep in various servers. When someone from Thailand enters the web He will receive information from the CDN server in Singapore or Hong Kong. Instead of having to run to the main server in America or Europe For more information, try to study from a reliable data source like Cloudflare .
• 3. Server-Side Cache (the cash on the server): is a more complex cache, such as the results of the database queries or dynamic So that the server itself does not have to calculate the same issue repeatedly every time someone requests

Where should I start? For most websites Beginning with Browser Cache and CDN Cache, the most obvious and fastest results will be seen. Which is an important foundation in accordance with the guidelines of http caching from Google Web.dev.

Example from the real thing: E ​​-commerce web that survived the end of the world with Caching

Think of the case of "Gadgethype" (assumed name). E -commerce website sells advanced gadgets. That had been in pain in the arrangement of Flash Sale innumerable times Every time I announced the popular product price The web will crash within the first 5 minutes, causing damage to both sales and reputation.

Turning mission: The team decided to overhaul using Website Caching Strategy to help.

• Step 1 (CDN): They use the CDN (Cloudflare) service to cast a product page, images, and all content that is Static Content (unchanged information).
• Step 2 (Browser Cache): Set the http headers to the browser of the users to keep the CSS and JavaScript file for longer.
• Step 3 (Server-Side Cache): Use a cache system (such as Redis) for Real-Time stock management to reduce the database directly.

Amazing results: In the next Flash Sale campaign, Gadgethype can accommodate 20 times more users at the same time! The website is completely silent. Fast load without interruption Customers order products smoothly. Sales rushed through the target. And the most important thing is to have an overwhelming praise from customers This is the power of the correct Caching strategy that changed from the "crisis" to a perfect "opportunity".
