Web applications use uploader feature to allow their users to upload images, videos, and other types of files. As these files are usually large in size, they take time to download when it’s necessary. This is whether the need for CDN providers arises. Over time, the use of CDN has been a very important need for websites for performance gain.
Setting up a CDN is easy and won’t take more than 5 minutes. Also, as some might think, CDN networks are not just for big businesses. If you pick your product and plans carefully, it won’t cost you much. In this article, we talk about the benefits of CDN providers and we introduce the Best CDN providers in the market.
What is CDN?
A content Delivery Network (CDN) is a network of servers and data centers dispersed throughout the globe. It enables the delivery of material with extremely low latency while supporting several concurrent users. CDN providers try to solve the problem of network congestion. Nowadays, most web applications use a lot of rich media resources like graphics and videos. This overall causes a traffic jam in networks. However, competition between these web services doesn’t allow them to have any performance loss. CDN providers guarantee that the material produced by web applications reaches users at high speeds, and without any quality loss.
How does CDN work?
CDN providers has a collection of servers that delivers material from a source server to end users around the globe by caching content nearby each user’s point of internet access. They initially request content from the origin server, which they copy and store as necessary elsewhere. They decrease the latency by physically storing content close to the user and minimizing the distance content has to travel. CDN providers have their servers across thousands of Points of Presence (PoP) all over the world. By dispersing the load geographically among several servers, this approach also lessens the strain on the origin servers.
This implies that the content you would like to view will load faster rapidly regardless of where in the world you are using your smartphone, tablet, laptop, or another internet-capable device.
Benefits of using CDN
The advantages of utilizing a CDN change based on the scope and requirements of the web application. However, the main advantages for the majority of users can be divided into five categories:
Speeds Up Website Load Time
Users see quicker page loading times thanks to optimizations such as employing a nearby CDN server to distribute material closer to website visitors. A CDN can lower bounce rates and lengthen visitors’ stays on the site because visitors are more likely to leave a slow-loading site. In other words, more users will stay on a website longer if the server load quickly.
Reduces Bandwidth Consumption Costs
A major cost for websites is the consumption of bandwidth for hosting. You can reduce the quantity of data that an origin server needs to provide by CDNs via caching and other improvements. This also lowers hosting expenses for site owners.
Increases Content Availability
Businesses must guarantee high content available on their websites to meet the rising consumer needs in today’s media-rich internet environment. The strain on the original servers to keep their websites from going down and to maintain the availability of their content increases as the volume of traffic increases.
Increases Content Redundancy
Large volumes of traffic or technical issues can prevent a website from operating normally. A CDN can manage more traffic and resist hardware failure quicker than multiple origin servers because of its globally distributed network.
Improving Website Security
Website security is increased because of CDN services. By distributing material among their servers, CDNs assist prevent web server overloads and can be an effective defense against cyberattacks that rely on delivering traffic spikes to important servers.
This is notably useful in DDoS assaults, where the attacker’s goal is to overwhelm a crucial DNS server by flooding it with queries.
CDN features you need to look for
To make life easier, we have summed up 5 of the best features you need to look for in your CDN provider:
Global Scale Network
Every area you want to enter must have a network presence. The provider should be a global content delivery network and can deal with this by using its own servers and data centers, collaborating with a local carrier or public cloud, or even using virtual machines.
Latency, which is effectively the beginning of content delivery, is the time from data generation and data transmission at consumer endpoints. By placing its centers close to the user and through route optimization, CDN providers can reduce latency.
Stringent Security Measures
When choosing CDN providers you need to take strict security precautions because online content might be vulnerable to a variety of dangers. Support for HTTPS (Hypertext Transfer Protocol Secure) is required in this situation, however, firewalls, advanced threat detection, and security analytics are optional.
The CDN providers should be able to transport content over the public, private, hybrid, and multi-clouds from any storage environment. For easier maintenance, you should also be capable of hosting a cloud CDN.
CDN providers offer advanced analytics with metrics that include valuable information about the performance of websites, audience behavior, and network constraints. Key performance indicators should be accessible in real-time or close to real-time.
