APT CONTENT DELIVERY NETWORK (CDN) SOLUTIONS FOR YOU
HIGH PAGE-LOAD TIME?
Content Delivery Network Solutions (CDN) are apt for you if...

Your website has a high page-load time: For instance, your website takes a lot of time to load, resulting in loss of customers.
You are struggling with high bandwidth costs: For instance, your servers are unable to handle the fast-increasing load of customers, thereby increasing the bandwidth costs.
WHAT IS CDN AND WHERE IS IT USED?
Content Delivery Network refers to content delivery services that manage a wide variety of content including text, graphics, media files, portals, live streaming, and video streaming. In order to provide easy and rapid access to the content for all the users. In other words, Content Delivery Network (CDN) is an internationally circulated system of web servers, designed to provide quicker access to the content. High availability with high performance is the principle on which CDN operates wherein the content is imitated all through the CDN. So, it exists in many places at the same time.

HOW IS IT HELPFUL IN SOLVING YOUR PROBLEMS?
CDN implies swift content delivery
CDN ensures fast content delivery, by making it easy for the users to access it within a shorter period of time.
CDN uses IP Analyst, GeoIP, and other smart technologies to bring content closer to the user in no time. Thereby increasing the possibility of engaging your audience through rapid content delivery.
CDN MEANS MULTIPLE WEB SERVERS

A few servers are unable to handle a large number of users accessing your content at a given point in time. Either you may choose to spend excess money on getting the bandwidth increase or you can choose CDN that deploys multiple servers to balance the load. That managing a large number of users. In case, one server gets down CDN reroutes the user requests to another server without obstructing the content services to the users.

CONTENT DELIVERY NETWORK - THE PROCESS
The picture depicts the flow of content to end-user:

In the first image where there is no CDN, the content will take more time to reach the user. Because it will go to all users from one centralized server from a single location.

In the second image where CDN is used, the content will take comparatively lesser time to reach the end-user due to distributed servers at nearby locations resulting in faster loading of content.

HOW DOES CDN ENSURE PERFORMANCE AND RELIABILITY
When a user requests for information, he gets duplicate of the information from the closest server location. There are multiple servers instead of one single central server in order to avoid congestion at one server. This improves Content Delivery Speed and Performance.
Information is our asset and if important data related to critical transactions are lost. It can have an adverse impact on revenues and transparency. Reliability is built through CDN because the distribution of content over multiple servers ensures that no data is lost during a particular server failure. Information is retained and can be recovered from another server without hurdles in ongoing transactional activities.
Performance and Reliability are the main considerations for web services that specifically affect productivity and consumer loyalty. To enhance these elements, engineers use business CDNs to cache (store) and convey web content. This incorporates static content, for example, images, videos, templates, JavaScript, files and documents.
CDN KEY MECHANISMS
At the point when a client visits a site that doesn't use a CDN. The browser downloads each referenced resource from a single origin server. If the origin is in the UK and the user is in China, every asset must be downloaded from over the world. For a situation like this, clients encounter longer page load times due to higher latency.
In Simple words we can say that there are two key mechanisms that explain how CDN works:

1. Keep important content circulated to various, globally distributed data centers so it is nearer to end users, and thus speedier to download.
2. Utilize server optimizations based on the content type to get that content to the user proficiently.

DISADVANTAGES OF NOT USING CDN

The main reason behind using a CDN is to enhance your user experience as far as speed is concerned, because as we know, “Speed matters”. The user is sure to bounce away from your website if it is unable to load content within a few seconds.

Ensuring that our user is getting a good experience is very important.
CDNs not only guarantee a faster experience to your user but also additionally help to anticipate site crashes in case of high traffic flow. CDNs help to disperse data transfer capacity over numerous servers, rather than enabling one server to deal with all traffic.

CDN SETUP AND IMPLEMENTATION COST

It may seem like setting up a CDN for your website is a troublesome task (now and then it is, depending upon the website complexity and size). However for most sites – CDNs are not difficult to implement. Basically, you have to tell the CDN which documents need to be duplicated across multiple servers and at which geographic locations.
Additionally, money is always a major concern when it comes to setting up a business. In CDNs, market custom plans are quite common. So, consulting a supplier of internet and getting some information about a custom value plan is always prescribed. Even the budget allocated by you becomes a source of help for the consultants or vendors who can then customize your plan to suit the size of your organization. While this may appear to be unimportant, it's recommended that a few vendors tailor their CDN solutions according to the organization's size and business verticals. Cost of CDN also depends on servers bandwidth, security needs, and region reach.

SIGNING OFF...
CDNs are a well known approach to distribute traffic and to run quick, reliable web applications at scale.
With a CDN arrangement clients download content from the third party servers. Rather than from distant inaccessible servers, enhancing execution of commands and speeding up content delivery.
