What is CDN?
A CDN is a group of servers spread across the globe that work together to deliver internet content quickly and efficiently to users. The CDN market is growing rapidly as more people use the internet. One of the key reasons why CDN providers are so important is that they help ensure that videos, images, and another content load quickly, no matter where in the world you are.
In today’s digital world, we love watching videos, playing games, or browsing websites online. But have you ever wondered how this content reaches us so quickly and smoothly? The answer lies in a Content Delivery Network, or CDN for short.
How does a CDN work?
Understanding how a CDN works in video streaming is quite fascinating. When you’re watching a video online, it’s important that the content loads quickly and without any interruptions. This is where a CDN comes into play.
Here’s a simple workflow of how a CDN works in video streaming:
- Content Preparation: First, the video you want to watch is prepared by the content provider. They break the video into smaller chunks and may create different versions with varying quality levels to accommodate users with different internet speeds.
- Uploading to the CDN: The content provider then uploads the video to the CDN, which stores it on multiple servers worldwide. This process helps ensure that the video is always close to the viewer, reducing the time it takes for the content to load.
- User Request: When you click on a video, your device requests the CDN for the content. The CDN determines the closest server to your location and the most suitable quality level for your internet connection.
- Content Delivery: The CDN server sends the video chunks to your device, assembling and playing the video. The process happens so quickly that you usually don’t even notice it. The CDN also ensures that the video continues to play smoothly, even if there’s a sudden surge in viewership.
- Adaptive Streaming: The CDN monitors your internet connection speed as you watch the video. If it changes, the CDN can adjust the video quality accordingly to provide a seamless viewing experience without buffering.>
What is Akamai?
Akamai is a CDN provider that provides a service called Content Delivery Network (CDN). Their main goal is to make the internet faster and more efficient worldwide. Imagine you’re trying to watch a video or visit a website that takes forever to load. That’s where Akamai comes in. They have a network of servers spread across the globe, which work together to deliver internet content quickly and smoothly to users.
Using advanced mathematical algorithms, the Akamai network intelligently routes and replicates content. They ensure to reach users from the closest server possible. As a result, we can enjoy a better online experience with faster load times and less buffering.
History of Akamai CDN
The history of Akamai CDN is a fascinating story that began with a challenge and evolved into a revolutionary solution to improve how we use the internet today. Let’s dive into the exciting journey of Akamai CDN.
Firstly, it all started with Tim Berners-Lee, the inventor of the World Wide Web. In 1995, he saw the future problem of internet congestion and posed a challenge at MIT to find a new and better way to deliver internet content. Little did he know that this challenge would lead to a groundbreaking service that would change the internet forever.
Next, an MIT professor named Tom Leighton decided to take up the challenge. As an expert in parallel algorithms and architecture, he believed the answer to the internet congestion problem could be found in applied mathematics and algorithms. To tackle this issue, he brought together a team of talented researchers.
Soon after, a bright student named Danny Lewin joined MIT in 1996 and started working with Dr. Leighton. With his strong computer science and mathematics background, Lewin made rapid progress in developing techniques to improve internet performance.
Dr. Leighton, Mr. Lewin, and their team created mathematical algorithms that allowed for intelligent routing and replication of content across a vast network of distributed servers. This innovative technology was the key to solving the frustrating problem of internet congestion that users were facing.
Ultimately, this academic challenge resulted in the birth of Akamai, a commercial service that has revolutionized how internet content is delivered. Today, Akamai CDN plays a significant role in ensuring that the internet remains fast and efficient for users worldwide.
