Amit Sharma — Cloud & Platform Engineering Leader
Zero-downtime cloud migrations, SRE-grade Kubernetes platforms, and the engineering programmes that ship them.
I design resilient cloud platforms and lead the engineering programs that ship them. From SRE-grade Kubernetes to zero-downtime migrations, I own delivery end-to-end across GCP, AWS, and Azure.
What I Stand For
Principles that shape how I work
Zero downtime is a constraint, not a goal
Teams that achieve zero downtime design for it from day one. It's not something you bolt on at the end — it shapes every architectural decision, from dual-run strategies to rollback triggers.
Migrations are org problems first
The technical challenges are rarely what derails a migration program. Misaligned stakeholders, unclear ownership, and InfoSec teams looped in too late — these are the real risks.
Platform engineering is about enabling autonomy
A good platform team makes itself invisible by enabling other teams to move fast safely. The goal isn't to run Kubernetes — it's to make the 100 teams using it not need you.

Insights
Technical & industry perspective
Debugging Across Layers Is the Platform Skill Nobody Hires For
Job descriptions list Kubernetes, Linux, networking, storage and virtualization as separate skills. The fault you get paged for lives in the seams between them. Here's how I work a problem that crosses layers, and why I think that's the skill to hire for.
Map What Exists Before You Draw What Should
Every migration and modernisation programme I've run started with a target architecture someone had already drawn. The ones that worked threw it away after discovery. Here's why the dependency map is the real architecture artefact, and how I build one.
Migration and Improvement Can Share a Window, Not a Change
Every migration customer eventually says it: if we're taking downtime anyway, let's fix a few things while we're in there. I say no every time. You can share the window and the error budget. You cannot share the change.
You Don't Own a Kubernetes Platform Until You Own the Layer Beneath It
Running self-managed Talos Kubernetes on Nutanix, with no cloud provider under it, changed how I design platforms on managed clouds too. Here's what the layer beneath teaches you.
Idle Capacity Is the Most Expensive Thing on Your Platform
I built my first capacity tooling in 2015, bursting HPC jobs to the cloud when the on-prem queue backed up. A decade later, on much bigger fleets, the lesson is unchanged: idle capacity and queue wait are the same number seen from two sides, and both should be on the dashboard next to latency.
Give the Agent the Keyboard, Keep the Approval
I've rolled out AI tooling across a delivery team and I'm building an agentic workflow that drafts Terraform and opens pull requests. The rule that's held up: agents may author, humans must approve, and the review bar doesn't move.

The Engineer Who Isn't Afraid
AI can now write code, generate infrastructure, and answer architecture questions. Most of the engineers I know are scared. I think the scared ones are asking the wrong question.

Replacing Google Photos with Immich
After years of Google Photos, I migrated my entire photo library to a self-hosted Immich instance. The migration took a weekend. The result is faster, more private, and — surprisingly — more capable for browsing.

Why I Built a Home Lab on a Gaming Laptop
Running Proxmox on a gaming laptop turns out to be a surprisingly capable home lab setup — enough CPU, ECC-free RAM that doesn't matter for learning, and a screen attached. Here's why I did it and what I learned.
