The verdict in one line

Running a legacy AIX, IBM i, or regulated BFSI core? IBM Cloud’s Power Virtual Server and Financial Services controls are built for exactly that. Running web, app, or e-commerce workloads that need to stay lean? Alibaba Cloud’s Mumbai-region ECS and OSS pricing gets there for less.

Which one for what

The clean decision guide for common Indian B2B scenarios. Pick the row that fits.

You run a 15-year-old AIX or IBM i core banking or ERP system

IBM Cloud. Power Virtual Server is the only clean path that skips the rewrite.

You’re an app or gaming team scaling fast and watching every rupee

Alibaba Cloud. ECS pricing and the Mumbai region keep the bill lean and the data local.

You’re a BFSI or insurance buyer with an auditor asking for FSI-specific controls

IBM Cloud for Financial Services. Built for exactly that conversation.

You sell into Southeast Asia or China alongside India

Alibaba Cloud. Its Asia footprint runs wider than IBM’s regional spread.

You need VMware workloads lifted into the cloud without re-architecting

IBM Cloud. Fully certified VMware solutions; Alibaba has no equivalent yet.

IBM Cloud vs Alibaba Cloud in India FAQ

Common questions Indian buyers ask. Answers grounded in current sources.

Is IBM Cloud or Alibaba Cloud better for an Indian BFSI workload?
IBM Cloud, for most regulated Indian financial workloads. IBM Cloud for Financial Services adds the audited controls BFSI auditors ask for, and the Chennai zone keeps data resident. Alibaba Cloud runs general compliance certifications but has no India-specific financial-services product.
Can I move an AIX or IBM i system to Alibaba Cloud?
Not natively. Alibaba Cloud runs on standard x86 infrastructure, so an AIX or IBM i core would need a full re-platform first. IBM Cloud’s Power Virtual Server runs AIX, IBM i and Linux on Power as first-class workloads, which is why it wins this specific case outright.
Does Alibaba Cloud keep my data inside India?
Yes, through its Mumbai region, live since 2018. Compute and storage stay inside India for DPDP purposes. IBM Cloud offers the same through its Chennai zone, with a second Mumbai Multi-Zone Region announced for 2026 alongside Airtel.
Which cloud is cheaper for a growing app or e-commerce business?
Alibaba Cloud usually comes out leaner for web, app and e-commerce workloads, because ECS and OSS pricing plus tiering are built for that scaling pattern. The real saving sits in right-sizing the instance, which is what the free 30-minute review is for.
Does Sirius Star sell IBM Cloud and Alibaba Cloud directly?
We size, provision and support both through their respective Indian authorised channels, GST-invoiced, from our Navi Mumbai team. We are not the hyperscaler. We are the partner who keeps the architecture, billing and support honest after the sign-up.
