Client: Retail Group operating across 9 countries
Cloud: AWS + Azure + GCP
Challenge:
Client lacked a cohesive multi-cloud strategy, leading to vendor lock-in, inconsistent security policies, and complex compliance issues.

Solution:
Sightsky Infotech developed a vendor-agnostic multi-cloud architecture with centralized identity, monitoring, and cost governance:

• Designed landing zones using AWS Control Tower, Azure Blueprints, and GCP Projects
• Implemented IAM federation using Azure AD
• Deployed a unified observability stack (DataDog, CloudWatch, Azure Monitor)
• Created automated guardrails using Policy as Code (OPA + Terraform Sentinel)

Outcome:
Improved vendor flexibility, reduced cloud spend by 23%, and met GDPR & PCI-DSS compliance globally.
