Case Studies

Cloud and infrastructure delivery

Selected engagements. Client names are withheld to protect confidentiality.

AWS · Cost Automation

Always-available retail platform at a fraction of the cost

Challenge: A multi-outlet retailer needed secure cloud hosting for its billing system without paying for servers running around the clock.

What we did: Hosted the platform on AWS EC2 in the Mumbai region, automated start and stop schedules with Lambda and EventBridge, and set up secure remote access with printer redirection.

Outcome: Around 40% fewer compute hours, with zero manual effort each day.

AWS → GCP · Migration

Production migration for an AI cybersecurity SaaS platform

Challenge: A fast-growing security platform needed to move its production environment from AWS to Google Cloud.

What we did: Planned and executed the migration of compute, storage and networking, coordinated the DNS cutover, and kept a clear rollback path throughout.

Outcome: Production running on GCP with a documented, repeatable process.

VMware · Enterprise Ops

Virtualisation operations for a global manufacturer

Challenge: A large manufacturing enterprise needed dependable day-to-day operations across its VMware estate.

What we did: vSphere and ESXi administration, capacity analysis with RVTools, PowerCLI automation and HPE server hardware support.

Outcome: A stable, well-documented and increasingly automated environment.
