What is a Content Delivery Network (CDN)?

A Content Delivery Network (CDN) is a network of distributed servers that aims to deliver content as fast as possible. CDNs verify a user’s geographical location and move the requested content to them from the nearest server in the network.
Let’s take an example of living in London, and you want information from an American site. The American site has a CDN with one server in Manchester. Rather than connect you to the server in America, the CDN will choose the shorter route and send you the information from Manchester.
While CDNs are typically global in nature, there are cases where a business may make a CDN local to their country or region. The US is a great example, as it is so vast that creating a CDN with servers near the east and west coasts makes sense.
CDNs are particularly relevant today, as more and more data needs to be distributed with minimal latency and on a global scale. Activities like video streaming and image distribution are network-intensive, and shortening the distance makes things much more efficient. Online video games also use CDNs, strategically placing servers in different geographic zones so most people can play without delays and lag.
Key Features of CDN
CDNs boast several unique features that make them a popular choice for content distribution. Some notable mentions include:
Origin and POP Servers
The most important feature of a CDN is the global distribution network. This network comprises an origin server and Point of Presence (POP) servers. A website or business’ content is stored on the origin server, a powerful machine with vast storage capacity. The POP servers are a network of servers strategically placed around the globe to accommodate the largest number of people in various regions.
For example, an American business may have the origin server in California and the POP servers in London, Germany, Tokyo, India, and Australia. Placing a server in these locations allows the American business to reach the global audience better. POP servers are usually leased through dedicated server hosting services with data centers in optimal locations.
Robust Traffic Management
Load balancing is also a defining feature of CDNs. By diverting traffic to POP servers, the origin server in addition to delivering content faster, is also deftly managing server load. CDNs have robust algorithms and protocols in place that maximize the power of a global server network.
High-Availability
Not only is a CDN a robust way to manage web traffic, but it also guarantees high availability. If a POP server goes offline, the network simply uses the next closest server to send data. If the origin server goes down, the cached data in POP servers is still sufficient to maintain uptime while the origin is fixed. Simply by being a distributed server network, CDNs guarantee high availability and minimal downtime.
Content Caching
Another major component of CDNs is the ways they optimize content delivery. Caching is the primary method of reducing latency and delivering content instantly upon request. Caching involves temporarily storing frequently requested data on POP servers. This allows the POP server to send the content to the user itself without waiting to receive data from the origin server.
Caching reduces latency and saves network bandwidth, delivering a great user experience and creating cost savings for the business.
Pros and Cons of CDN
CDNs are the backbone of modern web design. Something so critical and impactful comes with its own advantages and challenges. We have highlighted the most relevant of these below:
What is Cloud Computing?

Cloud computing is a service that focuses on delivering computing services over the Internet. While CDNs primarily provide information, cloud computing deals with processing information. When businesses leverage cloud computing, they are utilizing an external network of servers to do computing tasks for them.
Cloud computing as a service encompasses a number of different web services. The major services under cloud computing include cloud storage, data processing and analysis, cloud networking, cloud databases, and cloud software. Cloud service providers typically provide cloud services on a pay-as-you-go basis,
Key Features of Cloud Computing
Listed below are some of the hallmark features of cloud computing that exemplify why it is so prevalent and beloved today:
On-Demand Self-Service
Cloud computing does not require human intervention. A physical server does not need to be set up first and go through layers of middle management. Businesses can just visit a provider’s webpage, request a cloud server for their needs, and start cloud computing.
Remote Network Access
Cloud computing services allow you to perform complex computations from anywhere. Cloud providers utilize technology like CDNs to ensure broad network coverage so you can access your resources without hassle.
Resource Pooling
Cloud services offer access to a vast pool of computing resources. Users can use as much as they need from the pool, and the rest is allocated to other tenants. This dynamic resource allocation allows for swift scaling and is unique to cloud computing. You will not find this feature in bare metal servers, as they require additional component upgrades or adjacent server setups for scaling up.
Disaster Recovery and Backup
Cloud services often include built-in disaster recovery and backup solutions, ensuring data is replicated and can be restored in case of a failure. Critical business functions can continue in the event of a disaster. This reduces the need for maintaining separate disaster recovery infrastructure.
Pros and Cons of Cloud Computing
Listed below are some relevant pros and cons of cloud computing, which must be kept in perspective during decision-making:
CDN vs Cloud Computing: A Detailed Comparison
CDN and Cloud computing are not competitive technologies. In fact, CDNs are often labeled as cloud computing services. The point of this comparison is to demonstrate how CDN differs from cloud computing and how these technologies complement each other. It can help your business decide whether to invest in a dedicated CDN for your website or go for the more cost-effective cloud solutions.
Definition and Purpose
CDN: CDNs are designed for the express purpose of delivering content as cheaply as possible with maximum speed and minimal latency. Businesses invest in CDNs because they compete on web traffic, and CDNs greatly boost audience retention. Fast websites keep eyeballs on the screen and can go so far as to triple the generated leads.
Cloud Computing: Cloud computing is an umbrella term that includes many different over-the-internet processing services. Everything from data processing to complex analytics and machine learning comes under cloud computing. The central idea is that things happen on an external company’s server, and you pay to use their servers to do what you need.
Use Cases
CDN:
- Media and content delivery
- E-commerce websites with a global audience
- Streaming services
- Websites with high traffic volume
Cloud Computing:
- Hosting applications and websites
- Data storage and backup
- Big data analytics
- Machine learning and artificial intelligence applications
- Development and testing environments
Performance
CDN: Performance in the context of CDNs is all about minimizing latency and maximizing speed. The design philosophy of CDNs is based on performance. It is a system built to reduce performance strain on a server and provide an excellent user experience. CDNs are best for global businesses with international audiences, as everyone gets to enjoy the same near-native website performance.
Cloud Computing: Cloud computing performance is entirely dependent on network speeds. You can commission the most high-spec cloud servers for the job, but a poor internet connection and network congestion can render it useless. As a whole, however, the servers themselves are highly efficient. Most cloud services offer top-tier performance and scalability; even the cheapest plans are more than sufficient.

Cost
CDN: CDNs are a major expense. They require a lot of time and coordination to set up. Typically, businesses utilize dedicated CDN hosting services that cover broad geographical areas. They can commission the entire CDN from one provider, making payment and management simple. CDNs are generally out of scope for content providers that do not need global coverage.
Cloud Computing: Cloud computing costs depend on the plan you opt-in to and your resource usage. Many cloud computing services offer plans that provide a limited amount of resources, and you pay for as much as you use. So if your cloud plan offers up to 20GB of storage but you only use 10GB, you pay for just that 10GB. Cloud computing is good for businesses with shifting needs.
Scalability
CDN: CDNs are built for scalability. The multi-server nature of CDNs means there is always room to accommodate high traffic. Load balancing allows for equal traffic distribution alongside high uptime with built-in redundancy.
Cloud Computing: Cloud computing is also highly scalable, with instant resource deployment for high traffic and dynamic downsizing for slow periods. Cloud infrastructure delivers unprecedented levels of flexibility.
Security
CDN: Offers security features like DDoS protection and SSL, but control over security policies is limited.
Cloud Computing: Provides comprehensive security features, including encryption, access control, and compliance certifications, but also presents potential risks related to data privacy and control.
Management
CDN: They require in-depth knowledge of servers and networking. Typically, businesses choose CDN hosting plans with a dedicated admin and 24/7 support.
Cloud Computing: Managed through user-friendly dashboards and APIs, but requires an understanding of cloud services and cost management.
When to Use CDN and Cloud Computing?
CDNs are optimal for improving your website’s content delivery speed and performance. It is especially relevant for a global audience, while local businesses can get by without it. On the other hand, cloud computing is the way to go if you require scalable computing resources, flexible storage options, and a range of services to support various applications.
The beauty of this comparison is that it highlights how CDN and cloud computing cover each other’s weak points. Businesses can deploy CDN and cloud computing together to elevate their business to new heights of performance, user experience, and efficiency.
