Video-On-Demands (VOD), a service that enables immediate downloading and viewing of videos, has been becoming a part of daily viewing habits for many people. Researcher has predicted that subscription VOD services will see their total global revenue increase from $44 billion in 2017 to $69 billion in 2023. The rising trends of VOD, such as iTunes, Netflix, Hulu, and many more have boosted the adoption of cloud-based services to provide users an uninterrupted streaming to the data they want to see.
With the increasing demand of VOD and other online multimedia services, business with traditional solutions will not be able to handle large and periodic business load fluctuations. This has created an urgent need for highly efficient and low-cost technologies. Therefore, the use of cloud technology becomes an inevitable trend in the multimedia industry as it offers massive storage, elastically scalable computing, extensive network capabilities, and lower costs. enterprises can now build cheaper platforms that provide enhanced availability and elasticity.
To assist enterprises in building a cost-effective platform that serves enhanced availability and elasticity, Alibaba Cloud provides Video On Demand solutions with powerful Content Delivery Network (CDN) and storage infrastructure capabilities. These solutions enable enterprises to support millions of concurrent viewers while ensuring an increased user experience.
These are four keys of cloud products for VOD involved to serve the market and provide the quality service for users with latency, bandwidth, and scalability issues:
- ElasticCompute Service (ECS)
Alibaba Cloud ECS gives your business a reliable yet scalable and on-demand compute capacity on the cloud. It also provides fast memory, help you to power your cloud applications and achieve faster results with low latency.
- Object Storage Service (OSS)
Alibaba Cloud OSS provides secure, massive, low-cost and easy to use object storage capabilities, enables you to store, back up, and archive large amounts of data in the cloud, with a guaranteed reliability of 99.9%.
- Content Delivery Network (CDN)
CDN resolves the delivery latency problem that is usually caused by distribution, bandwidth, and server performance issues. Alibaba Cloud CDN will ensure you to accelerate the content distribution to all users across the globe.
- Server Load Balancer (SLB)
Alibaba Cloud Server Load Balancer (SLB) distributes and manages sudden spike traffic to improve the service capabilities of user’s applications, minimize response time, and ensure high-availability.
This solution is divided into three modules: video uploading, video broadcasting, and system management.
1. Video Uploading Module
Video files are stored in Object Storage Service (OSS) while the segment index is stored in an RDS database. OSS can also be directly integrated with Media Transcoding and CDN to provide video file transcoding and delivery capabilities.
2. Video Broadcasting Module
This module creates an external web service for real-time viewing capabilities. The Server Load Balancer receives access requests from user terminals and submits them to ECS (web servers) for processing. The web servers then perform user and device verification, retrieve the index database, and search the video index to retrieve the required videos.
3. System Management Module
This module manages user information, devices, and other related services.
