AWS Cloud Services & Migration in Kolkata

We begin with an assessment of what you are running today — dependencies, data volumes, licensing, compliance obligations and the real cost of downtime for each workload. Some systems lift and shift cleanly. Some need re-platforming to be worth moving. Some genuinely should stay where they are, and we will tell you which.

Migration then runs in waves, lowest-risk workloads first, each with a tested rollback path. Cutovers happen in maintenance windows with the old environment intact until the new one has proven itself.

Most AWS bills contain 30–40% waste: over-provisioned instances, unattached EBS volumes, idle load balancers, forgotten snapshots and production-sized staging environments running through the night.

We right-size against real utilisation data, apply Savings Plans and Reserved Instances where usage is predictable, move suitable workloads to Spot, lifecycle old data into S3 Glacier, and set budget alarms that warn before the invoice does. Cost reviews are part of managed service, not an add-on.

Cloud security failures are almost always configuration failures. We implement least-privilege IAM with no long-lived root usage, private subnets with tightly scoped security groups, encryption at rest and in transit, CloudTrail audit logging, GuardDuty threat detection and enforced MFA.

For resilience we design multi-AZ deployments, automated backups with tested restores, and documented recovery procedures matched to an RTO and RPO you have actually agreed to — not assumed.
