Challenges

  • to accelerate video content streaming in the VOD (video on demand) platform;
  • to promote high-speed and ultra-low latency while delivering UNINTER's content to more than 300,000 students throughout Brazil;
  • to reduce data and bandwidth consumption in the origin infrastructure; and
  • to improve the availability and reliability of the distance learning platform.

Benefits

  • advanced and unlimited cache settings, charged by usage, to deliver content to dozens of Azion's edge locations in Brazil;
  • about 1.2 PB of data transferred directly from Azion's Edge in 2020, an offload equivalent to 90% of the total amount;
  • 90% savings in bandwidth consumption, an average reduction of 366 Mbps during 2020, when all face-to-face students migrated to distance learning due to the Covid-19 pandemic; and
  • 100% service availability throughout Brazil, enabling students to study online anytime with video content that loads rapidly on any device.

Challenge

UNINTER is a reference in distance learning in Brazil, due largely to their advanced Virtual Learning Environment system, AVA (Ambiente Virtual de Aprendizagem, in Portuguese). AVA is accessed by more than 300,000 students, who matriculate from more than 700 cities in Brazil.

Speed, reliability and availability are crucial factors in providing students the best possible learning experience. In practice, this means:

  • video lessons that load more rapidly, with ultra-low latency;
  • content and features that can be accessed using any device; and
  • a distance learning platform that is available 24/7 to all students.

Faced with these challenges, UNINTER prepared itself for a future with more devices and a higher demand for connectivity, both of which will increase as 5G expands across the country.

Solution

UNINTER entered into a partnership with Azion in 2017 to replace its legacy CDN solution with a platform offering high-performance, high-availability solutions designed to meet the VOD (video on demand) application’s demands.

Complemented by microcache rules that can be built with Edge Cache, Edge Application enables content delivery acceleration through the edge, allowing UNINTER’s students to watch video lessons using any device. These lessons are delivered with ultra-low latency, even in locations where the Internet connections are slow.

In addition to the large number of videos available through the learning platform, UNINTER produces more than 20,000 videos – the equivalent of 10,000 feature films[1] – each year, Azion Edge Cache provides the scalability needed to add this content without infrastructure complications.

Using data intelligence to manage content delivered directly to the edge, UNINTER’s experts choose how long content should remain in the cache, as well as which content is allocated to the first cache layer, L1 Cache, and which videos are delivered through the additional layer, Tiered Cache.

Tiered Cache allows videos not stored in the first cache layer to be transferred through a second cache layer between Azion’s Edge and UNINTER’s servers, resulting in content delivery 30x faster than the cloud[2] and reducing workload in the origin infrastructure.

Results and impact

Approximately 90% of UNINTER’s application data was transferred directly to Azion’s edge locations. Additionally, 85% of all content accessed by UNINTER’s students was delivered through Tiered Cache.

Considering the reduction in bandwidth consumption, in 2022 alone, over 2.3 PB of data were delivered at the edge, which enabled UNINTER to save an average of 520 Mbps of bandwidth in its origin infrastructure.

The gains from Azion’s Platform enabled UNINTER to promote relevant actions during the pandemic crisis. This included providing 19 free online courses, open to everyone in Brazil, with the same level of excellence of UNINTER’s graduate and postgraduate courses, of which there are approximately 250.

“The Azion Platform has provided us with the flexibility we needed to manage the delivery of a large volume of video content to students enrolling at UNINTER hubs across Brazil and thus provide experience at a speed essential for quality distance education.”
