Let’s start with a small example so that you can easily understand what Cloudflare is and why you should use it.  Because the Cloudflare issue is very similar to this example.

When one becomes more popular, many enemies are created (jealous person).  As a result, a guard or bodyguard is needed for his protection.  Who is ready to repel any attack on that person?

Cloudflare is one such protector or guard.

So let’s know now what Cloudflare is, why and how to use it.

What is Cloudflare?

Cloudflare is not a hosting or domain provider.  You may be wondering, why is Cloudflare needed?  Cloudflare hosting, even if it does not give you the benefit of a domain, is enough to make you interested in using Cloudflare.

To put it simply, Cloudflare is a third party, a layer, a medium.  But there is no third party that is harmful to you, to your visitors.  Rather the opposite, i.e. beneficial third party or medium.

Cloudflare gives you more benefits besides CDN, DDoS Protection, and Web Optimization etc.  Which will keep your site fast and secure.  So, Cloudflare is a layer that acts as a bodyguard for your website.

Why use Cloudflare?

What is Cloudflare, we found out.  Now that we need to know why we use Cloudflare?  If there is any shortcoming in understanding what I have discussed above so far, it will be clearer now, Hopefully.

For your convenience, I want to explain in short in simple language.  Suppose your site name is example.com.  Taken from a provider like your domain & hosting from BlueHost, HostGator or GoDaddy.

Now think, when a visitor visits your site, that visitor will be able to visit your site directly.  Visitors who come this way will visit your site directly.  There is no problem.  But there is no guarantee that all visitors will be real visitors.  Hackers, robots, crawlers can all come here with visitors.  And you can also access your site directly.  This can damage your site.

 

Now here if you use Cloudflare the image will be different, but you will not lose your visitors.  If you use Cloudflare on your site, all visitors, attackers, robots, whatever.  Not everyone will access your site directly.  When someone wants to visit your site by typing example.com in the address bar, take them directly to Cloudflare instead of directly to the data center of your hosting server, then they will be able to visit your site.

 

Now you may be wondering why so many twist patches are needed?  Yes, of course.  When a normal visitor comes, they will be able to visit your site very easily.  But when an attacker comes to your site, Cloudflare will prevent them from entering your site.  That way, it will also prevent robots and others who are not a benefit to your site.

 

Now you may be wondering, how will Cloudflare understand who is a normal visitor and who is an attacker?  Yes, there is a way to understand that.  Cloudflare has a number of IP addresses that all the IPs used by the attackers are blocked by Cloudflare.  And when someone comes to visit your website from such an IP, Cloudflare will block their access.

If you look at the image below, you will easily get a clear picture of what Cloudflare is and why you should use it.

Hoe Does Cloudflare Works?
                                                                       This is How Cloudflare Works?

Cloudflare’s data center facility

The Cloudflare System has data centers in more than 150 countries on six continents.  As a result, your site is fast.

Now I am giving a light explanation of how fast it is!  Suppose the data center of the people from whom you have hosted your site is located in America.  So when a visitor visits your site from Bangladesh, India.  Then your site will take a little longer to load.  Because America is far away from Bangladesh and India.  So ping will increase here and your site will take time to load.  Again when someone visits your site from America, it will take time for the website to load while visiting from Bangladesh or India; It will take many times less time to load.  Since your site’s data center is located in the United States.

But when you use Cloudflare on your site, your site can be visited very quickly from all places.  Because as I said before, Cloudflare’s data center is located all over the world.

Why a quick visit?

When you add your site to Cloudflare, your site will read the essentials of your website.  Then all the information on your site will be sent to all the data centers in the world where Cloudflare has data centers.  Resulting in when a visitor would like to visit your website; Cloudflare then detects its IP from that visitor’s Cloudflare’s data center, and your site will “sleep” with that visitor.  For example, when a visitor wants to visit from Bangladesh, Cloudflare will see which data center is closest to Bangladesh.  Your site will show visitors from the data center that will be very close to Bangladesh.  In this way, it will be the same for the visitors of any country.  As a result, your domain can be visited very quickly from all over the world.

Advantages in case of server problems

Cloudflare has many advantages, one of which is that there are times when there is a problem with the server causing your website to go down.  But if you are using Cloudflare, your website will not be down even if your server is down for any reason.  Cloudflare holds a catch on your site, so if a visitor fails your server for any reason, Cloudflare actually “sows” your website to that visitor from its catch.  Looking at the screenshot below will make things easier for you.

How Cloudflare's Cache Serving are Working?
                                                                               How Cloudflare’s Cache Works.

The site is not live due to server problems but there is no problem visiting the site.  This is because the site has the advantage of using Cloudflare and there is no fear of losing visitors.  Here the visitor can easily visit from the catch of Cloudflare.  Many visitors may not realize that the site is offline.  The website will “live” again when the server problem is resolved.

Cloudflare Pricing Plan

Cloudflare has four types of packages.  One of which is free.  You can use the free package if you want.  However, you will not get the benefit of using all the features in the free package, it goes without saying.  However, free use will also benefit a lot.  You can view their dashboard whenever you want by opening a free account.  Where you can see all their features.
