Couple of very high level takeaways I could get from this podcast: 1. Keep all features behind a feature flag.This helps when you need to turn something off that's breaking production without doing a code release. 2. Wherever possible have a stand by setup like a static api that can keep your most business critical services up to ensure no customer/business impact in case a disaster strikes your system. 3. Run time auto scaling of DB capacity doesn't necessarily work for use cases like live streaming. You need to scale up before traffic surges. 4. Careful planning and back of the envelop calculation for all system components that are likely to get impacted by traffic surges. Like DBs, Kafka, CDN etc.

The way Prachi broke down and explained the intricacies of scaling and load handling for high-traffic applications like JIO Cinema is truly commendable.

@factfry1191 2 ай бұрын

Rule 1. If it works, leave it Rule 2. Preplan things Rule 3. Always assume that things will fail 100% and have backup ready Rule 4. Feature flags are superb In short, system design requires presence of mind and future planning (generally taking peak cases)

Feature flag (keeping in config service, based on geography), Charles testing tool, Exponential backoff for API retries, Request flow ( client -> Multi CDN -> LB -> Origin server -> DB), DB autoscaling is not recommended (takes lot of time 45 mins from her example for scaling 5 instances) (prescale is recommended after some calculations), Increasing TTL of caches when there's a hockey spike (can or cannot help), API personalization (serving static response when having this hockey spikes), Always Prepare for plan B,C,D, Multi CDN Optimizer (decides where to send the traffic, used for live streamings), Cache Offload < 90%, Designing cache policy in CDN is important (offloading cache monitoring), Kafka, DNS issue mitigation at backend,

Key notes: Feature flags, Circuit breaker pattern, APM, Kubernetes, Client Caching, Multi cdn optimiser, Cache offload, Kafka distributed system, Ads timing is manual, Ad personalisation is on the server side.

Hey @arpit, can you get someone from IRCTC technical team who can get us understanding on Tatkal mechanism. I believe what Amazon, hotstar, jiocinema do in their seasons(be it ipl, billion day sale etc) irctc handles far more requests on daily basis during Tatkal.

The ad insertion part was quite interesting for me, I did not realize that even the ads that we see during the games could be personalized and inserted based on different strategies. SCTY-35 markers was something completely new to me. The guest really had an end to end grasp of the whole solutions and was able to present a very coherent picture. Loved the podcast :)

Can we take a moment to appreciate the engineers involved in this, they stretch their time , compromise connections with their families for us to have a seamless experience, it’s a long work for 2 months and hope they deserve necessary appreciation and bonuses for their time. Yes , tech is just one aspect, but I hope asking questions like how the team is able to manage the work load is also very important.

Great insights, mostly when you see these kind of things people throw around standard fancy terminologies, but here its just from pure experience, deciding on base64, multiplication factors, one small change * the number of API requests etc... Enjoyed watching this.

Thanks Arpit and Prachi. Interesting questions covering end to end flow and very well put in-depth answers. Looking forward to the next episode! One question on personalized Ads insertion: * Why can't we pre-determine personalized Ads for a user in advance and play them during the break? I think bucketing a user based on certain user parameters is a good work around for now. pros: * More personalization (More revenue) * Not much time is spent on choosing an Ad: Since we would already have a list of Ads to pick from, there will not be much time waste to select an Ad during break. cons: * Waste of compute/memory resources to personalize Ad for a user who never watches the stream till they get to Ad break. Some more follow up questions: * How we can know more about user? This brings more number of Advertisers on the platform. * Can we add Ad bidding in this high concurrency streaming situation. Following is another interesting question for me to dive deep: * How can we show a particular Ad to exactly 'X' number of people? i.e. No over delivering or under delivering.
