A cloud based software architect designs how applications run on cloud infrastructure: tenancy model, networking, identity, data stores, CI/CD, disaster recovery, cost controls, and security boundaries.
For hospitality SaaS, that means multi-property isolation, regional resilience, partner API gateways, and payment-aware segmentation—not just lifting VMs to the cloud.
Nitin Rana has architected and operated hospitality Booking Engine and PMS workloads on AWS, including patterns for multi-AZ availability, managed databases, API layers, observability, and secure integrations.
Cloud architecture decisions are tied to product outcomes: faster partner onboarding, safer payment processing, and predictable scale during peak booking seasons.
Identity and least-privilege IAM, network segmentation, encryption in transit/at rest, backup and restore drills, blue/green or canary releases, and clear ownership of SLOs.
Cost architecture matters too: right-sizing, caching, async processing for OTA/PMS sync, and avoiding chatty cross-region designs.
Modern cloud based software architects also plan AI infrastructure: model gateways, vector stores, private LLM options, and agent runtimes that reuse the same IAM, logging, and compliance controls as core products.
