How to optimize video delivery and streaming for a website with CDN?

Vietnam is witnessing a strong surge in video content within online business activities. According to Kepios, 82% of Vietnam's population uses the internet, and 98% of them access the internet via mobile devices. Video-sharing platforms are also highly popular, with 71% of Vietnamese people using YouTube, 58% using Facebook Watch, and 47% using TikTok (Wearesocial). These numbers indicate that video is not just a trend but an essential part of the daily digital life of Vietnamese people.

According to HubSpot, posts with videos receive 83% more engagement than those without, highlighting the appeal of video to users. Instagram reports that short videos like Reels have a higher average engagement rate compared to other formats, specifically 3.21% compared to 1.08% for Stories.

Video marketing offers numerous outstanding benefits for businesses. According to OptinMonster, using video can increase click-through rates by up to 94% compared to text-only content. Cisco states that video accounts for 65% of website traffic. Additionally, 72% of consumers say that video makes them trust a brand more, and 80% of consumers want to see more videos from their favorite brands (Wyzowl). These statistics underscore the importance of integrating video into a business’s development strategy to attract and retain customers.

In this context, livestreaming is becoming a significant and effective trend for businesses. Recent figures show that livestreaming not only boosts sales but also improves engagement and brand recognition. For instance, Droppii organized livestream sessions combined with direct exhibitions during the "90-Day Speed Campaign," achieving an impressive sales figure of 344.022 billion VND with 678,777 products sold. These results demonstrate that investing in livestream sessions not only provides short-term revenue benefits but also helps businesses build stronger relationships with customers.

Using videos and livestreams to enhance business efficiency is becoming increasingly popular worldwide and in Vietnam. However, businesses also face numerous challenges when implementing this strategy, especially concerning website performance and capacity.

Buffering and Lag Issues

One of the biggest problems when uploading videos or livestreaming is buffering and lag, which directly impacts the user experience. According to Google, even a one-second delay in page load time can reduce conversion rates by 7%. Users tend to leave a website if the video does not play smoothly, resulting in lost business opportunities.

Research by Portent shows that 47% of users expect a webpage to load within 2 seconds. If the load time is longer, users may abandon the site and move to another. Forrester reports that each additional second of load time can cost businesses 7% in conversion revenue.

If videos lag or fail to play when users access them, businesses lose favor and credibility. This affects the company’s image, reliability, and growth potential. Therefore, businesses should prioritize finding and integrating solutions that support stable, smooth video playback and livestreaming to enhance user reach, brand loyalty, and user experience.

High Web Capacity Consumption

Videos and livestreams consume a significant amount of storage and bandwidth, placing pressure on the company’s servers and web infrastructure. According to Cisco, video will account for 82% of all internet traffic by 2022. This can lead to high bandwidth costs and slow down the website if not managed effectively.

The consumption of web capacity also affects load-bearing capabilities. When the system has to handle a large number of access requests simultaneously, proper resource allocation and flexible scaling become crucial. According to Google’s 2020 report, the number of DDoS attacks on financial systems increased by over 300% compared to the previous year, highlighting the urgent need to enhance system load-bearing capabilities. This necessitates businesses to seek solutions that optimize web capacity and enhance load management to meet user demands.

Poor and Unstable Video Quality

Unstable video quality is a major challenge, especially when users access content from different regions with varying internet speeds. Low-quality or interrupted videos can leave a bad impression and reduce engagement rates.

A report by Limelight Networks indicates that 23% of users will abandon an online video if they encounter slow load times or interruptions. Furthermore, 62% of consumers who have a poor experience with online videos are less likely to return to the same service. This underscores the importance of ensuring stable video quality to maintain customer satisfaction and loyalty.

Security and Copyright Issues

Videos and livestreams on websites are at risk of unauthorized access, particularly without proper security measures. According to IBM, the average cost of a data breach is approximately $3.86 million. Data loss or theft can cause significant financial and reputational damage to businesses.

Security and copyright infringement are critical challenges when businesses upload videos and livestreams on websites. Protecting content from unauthorized access and copyright violations is vital not only to safeguard intellectual property but also to maintain customer trust and loyalty.

Amid the rapid growth of video and livestreaming, ensuring a stable and secure system is crucial. An effective solution to achieve this is utilizing a Content Delivery Network (CDN). Not only does a CDN optimize page load speeds, but it also enhances load capacity and security for online services.

By caching content across multiple edge servers worldwide, a CDN allows users to access videos from the nearest server, minimizing transmission time and the risk of buffering or lag. This reduces the load on the origin server and ensures quick page load times. According to research by PageSpeed Insights, using a CDN can reduce page or application load times by up to 50%, a significant figure in retaining users.

CDNs provide user authentication mechanisms to ensure that only authenticated users can access content. Additionally, CDNs enable setting access control rules, such as geo-blocking to prevent access from unauthorized regions, or time-based access restrictions.

Moreover, CDNs offer protection against increasingly sophisticated cyber attacks, ensuring the safety of transaction data and customer information. A Cisco report indicates that the number of DDoS attacks doubled from 7.9 million in 2018 to 15.4 million in 2023, making the use of CDNs to protect layers 3 and 4 of the system more important than ever.

Implementing a CDN not only optimizes video streaming and distribution but also fortifies the security and performance of your website, making it a critical investment for businesses looking to enhance their online presence and user experience.
