OTA Updates
Why OTA Rollouts Fail in Automotive — And What Nobody Tells You Before Deployment
OTA updates in automotive are nothing like your phone update. Here are the failure modes that catch engineering teams by surprise.

About Me
10 Years Inside Automotive Software
I am Utsav Krishna — an automotive software engineer who has spent over a decade building the systems that power modern vehicles. ECU development, OTA update architectures, middleware stacks, and now Software Defined Vehicles.
The automotive software industry is going through its biggest transformation since the introduction of fuel injection. Every OEM is scrambling to shift from hardware-defined to software-defined architectures — and most engineers, managers, and companies are navigating this without a clear map.
I write to create that map. Clear, honest, opinionated writing on what is actually happening inside automotive software — not the marketing version, the engineering reality.

AUTOSAR Classic Is Not Dying. But It Is Changing — Here Is How
Everyone in the SDV conversation says AUTOSAR Classic is legacy. Here is why that is wrong, and what the actual transition looks like.
