Reaching Remote Learners Globally Using Amazon CloudFront with Doping Hafiza

Founded in 2011, Doping Hafiza is an educational technology company that provides video-based learning environments for Turkish primary, middle, and secondary school students. Using machine learning and other advanced technologies, the company helps millions of students prepare for exams with personalized studying programs, coaching services, lectures, and more. Before migrating to AWS, Doping Hafiza relied on several on-premises systems to store its data and delivered educational content to students using multiple websites and video players. “Doping Hafiza uploaded all its video content to public streaming services and embedded those videos on its website,” says Gizem Gür, senior solutions architect and cofounder of Sufle. “One of those public providers asked for thousands of dollars because these videos generated a large amount of traffic. This is when Doping Hafiza engaged Sufle.”

As an AWS Advanced Tier Services Partner, Sufle has supported organizations in their digital transformations for over 10 years. The company won AWS Partner of the Year for Turkey in 2022, a recognition of its success and expertise in the field. After participating in a webinar hosted by Sufle, Doping Hafiza saw an opportunity to modernize its content delivery network. “Doping Hafiza wanted a solution to host all its content, optimized for millions of users throughout Turkey and beyond,” says Gür. “The video-based learning environment required minimal latency and conversion because students might not have a very good internet connection or speed at home. After this engagement, we started developing and designing the new infrastructure together.”

With help from Sufle, Doping Hafiza migrated its data from multiple on-premises data centers to AWS. It uses 32 AWS services to host and deliver its content; in particular, the company has centralized its educational media on Amazon CloudFront, a content delivery network service built for high performance, security, and developer convenience. “Doping Hafiza relied on different solutions to host paid and free content. Before, it was not possible to accomplish this on a shared system,” says Gür. “On Amazon CloudFront, we were able to centralize the videos and make it possible to stream both types of content from one place.”

With the global scalability of Amazon CloudFront, Doping Hafiza increased the speed of content delivery by five times. Additionally, the company has not seen any interruptions or downtime since migrating to AWS, which has improved service quality. “Before the migration, we had some problems with availability and latency. Sometimes, our service crashed,” says Habil Bozali, head of software architecture at Doping Hafiza. “In the first 6 months on AWS, we saw no issues with Amazon CloudFront or any other AWS media service.” All Doping Hafiza’s data is stored, encrypted, and versioned using Amazon Simple Storage Service (Amazon S3), an object storage service offering industry-leading scalability, data availability, security, and performance. Using Amazon S3, Doping Hafiza can manage and search for content in a centralized location rather than multiple systems, reducing the time and effort to access storage by 95 percent.

Before migrating to AWS, Doping Hafiza relied on a costly, nonoptimized third-party solution to transcode and host some of its videos. Now, it uses AWS Elemental MediaConvert, a file-based video transcoding service with broadcast-grade features, to transform video content to different output options and deliver adaptive streams to users with Amazon CloudFront. Using this service, the company can automatically convert all high-quality video streams to different bit rates, including low-level qualities for students who do not have a good internet connection at home. “Before, we would need to download the video, convert it, and upload it to a different backup service and to different content delivery networks, which was time consuming,” says Bozali. “Now, we can upload a video and convert, transport, and distribute it automatically to our content delivery network using AWS services.” By adopting this solution, Doping Hafiza has reduced its processing, storage, and delivery costs by 30 percent.
