Growth of AI Through a Cloud Lens 🍼

Do you remember the start of cloud computing? There was a lot of scepcis, like "real business won't use it", shifting to "Fortune 500 companies won't use it", until everybody was using cloud. Mitchell Hashimoto, a CTO of Hashicorp, recalls this trends and tries to analyze if it applies to the raise of LLMs. How much impractical for business the LLMs are? And how this area of impracticality will shrink in the future? Get a long read!

Media Understanding Platform for ML Innovations 👷‍♂️

Netflix serves you content, but it also should help you finding it. Previously, the editor had to go through the hours of the shows hosted on the platform to pick up highlights or choose the engaging, story-telling dialogues. So Netflix decided to improve the efficiency of editors' work, introducing a solution to find the scenes in the show by a request, like "red racing car" or "dialogue with tears". Find out, what solution they ended up implementing!

The cost of Architectural Complexity 🤟

It's pretty obvious that the more complex architecture you have, the more it's operation will cost. However this is not the only penalty you might experience. For example, the number and severity of software bugs increases with the complexity as well. What else? Follow the Abi's review of the paper from 2013 on the cost of architectural complexity.

Lambda vs Kappa Data Processing Architecture

The last one for today is the guide on the 2 approaches to the data processing architecture: Lambda vs Kappa. It has nothing to do with Lambda functions though. So the former is more complex and includes 2 data processing streams for realtime and batch processing; the latter is simplified and trying to do the job with only a single pipeline treating everything as a data stream. Find more details inside.
