The demand for quality video delivery is growing at unprecedented rates across the world. Be it OTT platforms or educational portals, gaming broadcasts or corporate webinars – today’s consumer requires an efficient and reliable delivery of video content with minimal latency and maximum availability.
However, effective video delivery is more complex than simply uploading your videos to a server. Each successful video streaming website is backed by a well-thought-out infrastructure which includes a set of advanced components. These include a streaming server and CDN technology.
And since video delivery is becoming an increasingly important aspect of running a business, it is crucial that companies learn how to leverage this technology in order to improve their performance and reduce delays.
Here, we will look into what is meant by cdns and streaming servers and explain how these two components help each other out in ensuring high-quality video delivery.
What Is a Streaming Server?
A streaming server is a specialized server that manages the delivery of video content to viewers.
In contrast with web servers, streaming servers are designed specifically for media delivery and optimization.
The tasks of streaming servers may include:
Video ingestion
Video encoding and transcoding
Stream management
Content storage
Live stream delivery
VOD streaming
Streaming servers are key components in providing:
Livestreams
Webinars
OTT
Gaming streams
VOD livestreaming
Without a streaming server, distributing videos on a large scale would become quite challenging.
What Is a CDN?
Content Delivery Network or CDN is a network of servers located geographically in order to deliver content nearer to the end users.
The CDN distributes content from numerous edge servers located around the world rather than one origin server handling all requests.
When an end user requires a video, then the CDN delivers content from the closest edge server available.
It helps to lower:
Latency
Buffering
Network congestion
Server load
CDN is utilized in many ways such as:
Websites
Images
Applications
Video streaming
Why Streaming Platforms Need Them Both?
Many believe that CDN could function just like a streaming server.
However, both technologies have their own tasks.
Tasks of Streaming Server
The streaming server is responsible for:
Storing source content
Managing streams
Encoding video stream
Creating streaming format
Tasks of CDN
The CDN is responsible for:
Global distribution of content
Reducing latency
Scalability
Traffic peaks handling
Working of CDN and Streaming Server Together
It is usually done through the following sequence of events:
Step 1: Video Uploading or Live Broadcast Input
Content producers upload their videos and commence live streams.
The video received by the streaming server.
Step 2: Transcoding
This involves converting the video into several formats and resolutions.
Some of these include:
1080p
4K
Mobile video versions
Step 3: Distribution via CDN
The transcoded content is then distributed through the CDN.
It caches copies of video on different edge servers.
Step 4: Content Requested By Viewers
When viewers watch the video,
A search for the nearest edge location occurs.
Video delivered from the nearest server.
Advantages of Implementing CDN along with Streaming Servers
Latency Reduction
Latency is influenced by distance in streaming.
The use of a CDN allows delivering content closer to users, thus minimizing the latency issue.
It is important for:
Live streaming
Sports streaming
Interactive streams
Scalability Enhancement
A single streaming server might be insufficient under high traffic load conditions.
A CDN is capable of spreading requests among multiple servers, which helps handle thousands or millions of users at once.
Bandwidth Savings
In case of no CDN implementation, all viewer requests will reach the origin server.
With CDN, the following takes place:
Most requests will be served by cached content.
Origin server bandwidth utilization reduces.
Such an approach could considerably save expenses.
Enhanced User Experience
Users can enjoy:
Fast startup of streams
Low buffering rates
High-quality videos
Reliability
User experience has a direct influence on viewer retention and engagement rates.
The Importance of GPU Dedicated Servers in Streaming Services
More and more modern streaming services make use of GPU dedicated servers to ensure better performance.
Processing in streaming involves considerable computation capacity needed for:
Encoding/decoding
Transcoding
AI optimization
Real-time rendering
Advantages of GPU Dedicated Servers
Speedier Video Encoding
Encoding process is drastically sped up by GPU technology.
Real-Time Transcoding
Absolutely necessary for adaptive bitrate streaming.
Artificial Intelligence Recommendations
Provides robust recommendation capabilities.
Improved Streaming Performance
Streamlines scalability during heavy traffic.
GPU technology is becoming more crucial to operate live streaming VOD services.
Difference Between Dedicated Servers & Cloud Hosting For Streaming
When considering hosting for streaming services, companies have options between:
Dedicated server setups
Cloud-based hosting
Both have their own strengths.
Advantages of Dedicated Servers
A dedicated server comes with:
Hardware exclusivity
Guaranteed performance
Higher levels of security
Exclusive resources
Perfect for:
High volume of streamers
Enterprise-level usage
Large media organizations
Advantages of Cloud Hosting
The cloud provides:
Scalability
Resource flexibility
Global accessibility
Inexpensive growth opportunities
Many companies use cloud servers together with dedicated servers for best results.
CDN and Live Streaming VOD Services
Contemporary live streaming VOD services experience certain challenges.
Those include:
Livestreams
On-demand videos
Multi-device support
Accessibility from all over the world
CDNs help overcome those challenges by making sure that the content is delivered fast no matter the location of the viewers.
A contemporary VOD platform without a CDN would have a hard time delivering a good experience.
CDN and 4K/8K Streaming
Due to ongoing progress in video technology, new requirements emerge.
Requirements for 4K/8K streaming include:
Better bandwidth
More efficient delivery
Advanced caching technologies
CDNs help distribute content more effectively and take pressure off the streaming server.
That is one of the reasons why CDNs have become an essential element of modern video streaming solutions.
Emerging Technologies for Streaming Infrastructure
Some of the emerging trends in this area include:
AI-based optimization
Such technologies can optimize:
Compression methods
Optimal bitrate
Content recommendations
Edge Computing
Doing calculations near the user decreases latency greatly.
GPU-based Solutions
GPU technologies will be in increasing demand in video processing.
Intelligent CDN routing
The next-gen CDNs will use artificial intelligence to select optimal routes for content delivery.

Conclusion
CDNs and streaming servers are not competing technologies; instead, they complement each other in order to provide efficient streaming infrastructure.
While streaming servers deal with processing content on the server side, CDNs deliver the content to users.
Together with technologies such as GPU dedicated servers, dedicated server infrastructures, and cloud hosting services, businesses can establish robust infrastructure to support their live streaming VOD demands.
As video consumption grows further, businesses need to think about the right streaming infrastructure now.
