@mickeynp @rafalwilinski Yes many didn’t understood the joke, they had cold start
English

@rafalwilinski serverless was always a joke for 99% of workflows.

@theprayagtiwari @FarOutAkhtar Do not name it “dil chahta hai 2”

let audiences guess
English

Hello @FarOutAkhtar, this is the best time to announce Dil Chahta Hai Part 2 with the same cast

@krishdotdev We are stretching this conv… nothing is from scratch back then it might be the obvious next step it was either this guy or someone else.
Being said that even to take the obvious next step is commendable in itself.
So kudos to Linus

@brankopetric00 IMO lambda’s are best for housekeeping tasks rather than any production stuff
English

Client chose AWS Lambda for everything because 'serverless is cheaper.'
6 months later:
- 300+ Lambda functions
- Cold starts killing user experience
- Debugging required checking CloudWatch across 50 log groups
- Bill was 3x higher than equivalent ECS
Serverless isn't cheaper. It trades infrastructure cost for operational complexity.
English

@brankopetric00 Because now with cloud it seems easy to scale the hardware so it has become the default solution.

Developer kept complaining our RDS instance was too slow. Wanted to upgrade from db.t3.large to db.r5.8xlarge.
Cost increase: $140/month to $3,400/month.
I checked query performance first:
- Query ran 47,000 times per hour
- No indexes on the WHERE clause columns
- Missing composite index cost 890ms per query
Added two indexes. Query time: 890ms -> 12ms.
Saved $39,000 annually because we spent 15 minutes with EXPLAINING.
Most performance problems are code problems disguised as infrastructure problems.

Time to expose the mess. A thread 👇
