To stay ahead of the competition in a fast-paced, cost-driven cloud services marketplace, LeCloud must innovate new services and revenue streams to retain customers and drive profit. By using future-forward data center solutions from Intel, LeCloud is able to reduce latency in its video transcoding and improve the user experience when streaming new 4K and H.265 real-time video services to millions of customers concurrently.

Challenge
The competitive and aggressively priced Cloud Services marketplace in China offers plenty of choice to enterprises and consumers but creates profitability challenges for Cloud Service Providers (CSPs). Global cloud ecosystem provider LeCloud must innovate new products and services frequently to retain customers and grow marketplace share. Meanwhile, cost-conscious customers and strong competition mean that LeCloud needs to deliver its services at a keen price point. With these competing demands, LeCloud needed to build a cloud infrastructure capable of supporting new high-performance, next-generation cloud services, while seeking the lowest possible total cost of ownership (TCO).

Solution
LeCloud sought to maximize the performance capabilities of its newest video transcoding cloud services while remaining able to supply customers at a more competitive price than alternative cloud service providers. To balance performance and price and establish the most cost-efficient hardware and software combination, LeCloud evaluated the new Intel® Xeon® Platinum 8180 processor against currently available solutions from Intel.

“The Intel® Xeon® Platinum 8180 processor is a powerful platform for our transcoding, and certainly will improve the user experience."

Result
With the Intel® Xeon® Platinum 8180 processor, LeCloud delivers video transcoding services with a 1.51X performance boost compared to previous generation Intel® Xeon® processor E5-2699 v4. The new processor allows LeCloud to reduce latency in video transcoding and deliver a smoother user experience for its millions of customers. Through specific software optimizations, LeCloud also uses Intel® AVX-512 – new to the Intel® Xeon® processor Scalable family - to deliver a further 22 percent performance improvement of its video transcoding solution over the previous generation Intel® Xeon® processor.1

Differentiated Cloud Services Demand Next-Generation Platform for Innovation
The Cloud Services marketplace is growing rapidly around the world but nowhere more so than in China, where the compound annual growth rate (CAGR) for the cloud computing industry is estimated at around 40 percent.2 Globally, analysts expect that spending on public cloud infrastructure will top USD 246.8 billion in 2017.3 In spite of this growth, a highly competitive market and cost-conscious buyers create challenges for CSPs keen to deliver services profitably and retain their customer base across billing cycles. Growing revenue and marketplace share requires CSPs to innovate new, differentiated services to satisfy the evolving needs of their customer base.

China-based CSP LeCloud continuously innovates to build marketplace share, launching differentiated services for its enterprise and consumer customers with a focus on video and media cloud. LeCloud subsidiary LeTV* is one of the largest video content providers in China and this content is delivered by LeCloud. To stay ahead of the competition, LeCloud needed to deliver intensive 4K and H.265 video content to its customers in real time without affecting media performance for any of the millions of concurrent users of its services. To ensure it retained its existing customers as well as driving new revenue with these services, the company needed to provide its innovative video cloud offerings at the lowest possible price point.

Balancing Performance and Price
In order to establish the most effective hardware/software combination to deliver its new 4K and H.265 video services cost-effectively, LeCloud evaluated the Intel® Xeon® processor Scalable family against the previous generation Intel® Xeon® processor E5-2699 v4. LeCloud also actively collaborated with Intel to take advantage of Intel® AVX-512 instructions within its video transcoding solution to boost performance.

LeCloud’s video transcoding solution is critical to delivering high-definition video content to customers in real time, without latency which can negatively impact the customer experience. The performance tests revealed that LeCloud can achieve a 51 percent performance boost using the Intel® Xeon® Platinum 8180 processor. Further software optimizations leveraging Intel® AVX-512 yielded an additional 22 percent performance improvement over Intel® AVX2 instructions, dramatically speeding up the video transcoding process.

The evaluation allowed LeCloud to understand the benefits of upgrading its data center to the latest Intel® Xeon® processor Scalable family.

Delivering Real-Time Video Transcoding
By running its video transcoding solution on the Intel® Xeon® processor Scalable family, LeCloud takes advantage of more cores and a higher memory bandwidth compared to the previous platform. This means that once LeCloud deploys the Intel® Xeon® processor Scalable family across its data centers, it will potentially be able to serve more customers with demanding high-quality video content using the same hardware configuration.
