A couple of days ago we published a case study on how Coca-Cola North America handles their vending machine’s systems with serverless. Today we’re going to talk about another titan that turned to serverless. As you may have guessed from the title, we are going to be talking about Netflix.
Netflix is a streaming service founded in 1997 and, believe it or not, started out as a Blockbuster alternative for renting and selling DVDs through the mail. Yeah, it was such a long time ago. And while they are still renting about 3 million DVD’s a year they are also the number one video streaming platform for TV-shows and Movies.
Netflix delivers 10 billion hours of videos to 125 million customers every quarter and to serve that kind of audience they use a wide range of highly complex infrastructure that relies mostly on AWS. Imagine what the servers that run Netflix look like? Petabytes of data in hundreds of thousands of files changed daily, served millions of customers in 55 countries.
At the moment Netflix has moved completely to the AWS cloud infrastructure and while a full seven years to make the move from their own data center might seem a long time for most people, they wanted to make sure that the problems they were facing while using the self-managed data center would not get imported into the cloud so they ended up basically rewriting every aspect of their service to make Netflix a true cloud-native application. You can read more about the journey to the cloud in an article written by Yury Izrailevsky, vice president of cloud platform engineering.
Publishers upload thousands of files to Netflix on a daily basis and every bit of those files need to be encoded and sorted before they end up being streamed to the user. Once the files get uploaded to S3, Amazon triggers an event calling an AWS Lambda function that splits the video into 5-minute chunks that get encoded into 60 different parallel streams that Netflix needs. Once the last part of the video gets processed they get aggregated and deployed using a series of rules and events.
Another way that Netflix uses AWS Lambda is for their backup system. As thousands of files get changed and modified on a daily basis Lambdas are checking if the files need to be backed up, they check the validity and integrity of the files, and if anything fails they can backtrack to the source of the problem and restart the process.
In the space of security, Netflix has thousands of processes that stop and start instances all the time and they use Lambda to validate that each no instance is constructed and configured in accordance with the system’s rules and regulation. They also use Lambda to create alerts and shutdown in the event of unauthorized access.
Next came efficiency improvements using better production monitoring and dashboards. This information was based on the events system that Netflix built for Lambda, through which events trigger validations to ensure that the configuration fits real-world needs.
The last step was to remove the responsibility of the servers that manage all of Netflix’s media. When Lambda is responsible for the server deployment, compliance, and configuration, Netflix can be confident that provisioning processes and responding to new business needs are fully handled.
To start reaping the true serverless benefits like Netflix today, sign up to Dashbird’s serverless observability platform.
In this article, we’re covering 4 tips for AWS Lambda optimization for production. Covering error handling, memory provisioning, monitoring, performance, and more.
In this article we’ll go through the ins and outs of AWS Lambda pricing model, how it works, what additional charges you might be looking at and what’s in the fine print.
Dashbird was born out of our own need for an enhanced serverless debugging and monitoring tool, and we take pride in being developers.
Dashbird gives us a simple and easy to use tool to have peace of mind and know that all of our Serverless functions are running correctly. We are instantly aware now if there’s a problem. We love the fact that we have enough information in the Slack notification itself to take appropriate action immediately and know exactly where the issue occurred.
Thanks to Dashbird the time to discover the occurrence of an issue reduced from 2-4 hours to a matter of seconds or minutes. It also means that hundreds of dollars are saved every month.
Great onboarding: it takes just a couple of minutes to connect an AWS account to an organization in Dashbird. The UI is clean and gives a good overview of what is happening with the Lambdas and API Gateways in the account.
I mean, it is just extremely time-saving. It’s so efficient! I don’t think it’s an exaggeration or dramatic to say that Dashbird has been a lifesaver for us.
Dashbird provides an easier interface to monitor and debug problems with our Lambdas. Relevant logs are simple to find and view. Dashbird’s support has been good, and they take product suggestions with grace.
Great UI. Easy to navigate through CloudWatch logs. Simple setup.
Dashbird helped us refine the size of our Lambdas, resulting in significantly reduced costs. We have Dashbird alert us in seconds via email when any of our functions behaves abnormally. Their app immediately makes the cause and severity of errors obvious.
