Cloud Migration in Delhi

Four routes appear in almost every cloud migration review, and each workload is assigned one in writing:

Each entry carries a route, an effort band and a rough cost, so cloud migration can be approved one system at a time by the people who actually sign it off.

• Rehost: — moving an image to an equivalent instance with no code change, preferred where the application already meets its controls in its current form.
• Replatform: — relocating the workload while replacing self-managed components with managed services that produce their own logs and patch records.
• Refactor: — redesigning selected pieces around containers or managed queues where the system is core enough to justify the governance effort.
• Retire: — closing systems that no longer operate, so the audit scope shrinks along with the estate itself.

Connectivity is designed with segregation in mind: dedicated circuits such as AWS Direct Connect or Azure ExpressRoute where traffic must not cross the public internet, firewall rules written before any workload moves, and hybrid DNS aligned so names resolve identically on both sides. Latency from Delhi offices to the chosen region is measured early, and our networking services survey records the path as evidence.

Access is federated to your directory over SAML or OpenID Connect so joiners, movers and leavers follow one process across both estates while cloud migration runs. Privileged roles are scoped, multi-factor authentication is mandatory for anyone who can alter infrastructure, break-glass credentials are vaulted and rotated, and every administrative action lands in an audit trail.

Four methods cover regulated data: staged replication over the internet for ordinary volumes, an accelerated transfer service when a deadline is tight, a dedicated circuit for continuous flows, and a shipping appliance where volume would otherwise saturate a link. Whichever is used for cloud migration, row counts, checksums and permission sets are compared before traffic is switched, and the comparison is retained as evidence.

Personal data gets its own treatment: fields are classified before transfer, masking or tokenisation is applied where a full value is not required in the target, and access to the migrated set follows the same approval path as the source. Logs of who touched what are kept with the rest of the evidence.

The pilot is a representative system whose controls are already understood, so the rehearsal can prove provisioning, agent installation, data synchronisation, monitoring, smoke tests and rollback against your existing standard. Findings are recorded and the runbook updated, giving later waves of cloud migration a method that has already passed once under realistic conditions.

Critical systems stay on the source while the target receives a copy of the traffic, both are compared over an agreed period, and the switch is authorised only once the numbers agree and the named approver signs. Windows sit outside working hours, and every step in the runbook is marked pass or fail for cloud migration.

Rollback is written and rehearsed before go-live: if checks fail after the switch, traffic returns to the source within the agreed recovery time, the cause is recorded with a date and an owner, and a retry happens only after the fix is proven. Short DNS time-to-live values and a named decision-maker are settled during the pilot of every cloud migration. Our backup and disaster recovery practice applies the same rehearsed discipline to day-to-day continuity.

Cloud migration cost modelling compares on-demand pricing for variable demand, one-year and three-year reservations for proven baselines and committed-use discounts for the ground between them, then adds egress, snapshot storage and log ingestion before you commit. For cloud migration, cost evidence matters too, because budgets here are approved against a document rather than a forecast. Entry-level cloud VPS plans suit pilots.

Entitlements are reviewed during discovery, because per-core minimums and mobility terms decide whether your own licences may be reassigned and at what price. We compare bring-your-own and marketplace routes for every product that matters, keep the calculations, and file them so a later audit of cloud migration has a dated answer to point at.

Region selection follows the duty rather than the default. Financial services workloads under Reserve Bank of India rules, listed-company reporting with SEBI, insurance records under IRDAI and personal data under the Digital Personal Data Protection Act are pinned to Indian regions, and we record which categories must stay inside India and which may travel so Delhi auditors can be answered from the document, during cloud migration and after it.

The month after cutover is reviewed against the plan: right-sizing replaces the generous instance shapes chosen beforehand, storage tiers follow real access patterns, orphaned volumes are switched off, and snapshots move to cheaper policies once retention is agreed. Alerts are tuned so signal is not lost in noise, and monitoring continues through server monitoring after cloud migration closes.
