The resulting architecture had the entire stream analysis process running in ECS on EC2, with groups of detector instances distributed across different ECS tasks to avoid hitting vertical scaling limits when adding new detector types.Īfter rolling out the revised architecture, the Prime Video team was able to massively reduce costs (by 90%) but also ensure future cost savings by leveraging EC2 cost savings plans. We also implemented orchestration that controls components within a single instance. This eliminated the need for the S3 bucket as the intermediate storage for video frames because our data transfer now happens in the memory. We realized that distributed approach wasn't bringing a lot of benefits in our specific use case, so we packed all of the components into a single process. In the end, the team decided to consolidate all of the business logic in a single application process.
The other challenge was due to reaching the account limit of the overall number of state transitions, because the orchestration of the process involved several state transitions for each second of the analyzed audio/video stream. The problem of high operational cost was caused by a high volume of read/writes to the S3 bucket storing intermediate work items (video frames and audio buffers) and a large number of step function state transitions. So, we took a step back and revisited the architecture of the existing service, focusing on the cost and scaling bottlenecks. We also noticed scaling bottlenecks that prevented us from monitoring thousands of streams. While onboarding more streams to the service, we noticed that running the infrastructure at a high scale was very expensive.

Marcin Kolny, senior software engineer at Prime Video, shares his team's assessment of the original architecture: After operating the solution for a while, they started running into problems as the architecture has proven to only support around 5% of the expected load. The team designed the distributed architecture to allow for horizontal scalability and leveraged serverless computing and storage to achieve faster implementation timelines. All audio/video data, including intermediate work items, were stored in AWS S3 buckets and an AWS SNS topic was used to deliver analysis results. AWS step functions were used as a primary process orchestration mechanism, coordinating the execution of several lambda functions. The microservices included splitting audio/video streams into video frames or decrypted audio buffers as well as detecting various stream defects by analyzing frames and audio buffers using machine-learning algorithms. The initial architecture of the solution was based on microservices responsible for executing steps of the overall analysis process, implemented on top of the serverless infrastructure stack. The Video Quality Analysis (VQA) team at Prime Video created the original tool for inspecting the quality of audio/video streams that was able to detect various user experience quality issues and trigger appropriate repair actions. It moved the workload to EC2 and ECS compute services, and achieved a 90% reduction in operational costs as a result.

Rising temperatures could also make the work of delivery drivers harder.Īnticipating this concern, Amazon said in its Monday press release said that the expansion of its delivery network won't compromise the safety of its employees, claiming the nature of the worker's jobs will remain the same.Prime Video, Amazon's video streaming service, has explained how it re-architected the audio/video quality inspection solution to reduce operational costs and address scalability problems.

One Amazon driver anonymously told Insider he was "completely overwhelmed" and "drained" when he was delivering a high volume of packages during Amazon Prime Day, the company's two-day summer sale that occurred from July 11 to 12. Next to it, you will also get to set up the recording tools. In that report, Amazon said that customers in those cities "can now receive hundreds of thousands of items within hours."īut more same-day delivery sites could also increase in the number of packages and stops for drivers, which in turn, could lead to harsher working conditions. It will let you select the resolution along with the section of the screen that you want to record. The news of the company's expansion of its same-day delivery network comes just months after Amazon ramped up its number of same-day deliveries for US prime customers around cities like Los Angeles, Phoenix, and San Francisco, according to its fourth-quarter earnings report.
