For IT heads, CTOs, and finance teams at Indian businesses evaluating whether to continue with on-premise storage infrastructure or migrate to cloud object storage.
The Illusion of On-Premise Cheapness
On-premise storage infrastructure feels like it should be cheaper than cloud. You buy the hardware once. You own it. You are not paying a monthly bill to a cloud provider forever.
This reasoning is correct about one thing — the hardware cost is a one-time purchase. It is incorrect about everything else. On-premise storage has a set of costs that do not appear on the hardware invoice and do not get included in most informal TCO comparisons. When you include them, the picture changes significantly.
This comparison is an attempt to do the full TCO calculation honestly — for a representative Indian mid-size business running approximately 100 TB of active storage — and to show where the break-even points between on-premise and cloud storage actually are.
The On-Premise Cost Model
Hardware acquisition: A modern NAS or SAN system with 100 TB of usable capacity, from a reputable vendor, costs approximately Rs.15–25 lakh for the hardware alone. This does not include networking equipment, rack space, power distribution, or UPS.
Hardware refresh cycle: Enterprise storage hardware has a practical lifecycle of 3–5 years before it needs to be replaced — either because of end-of-support on the hardware platform, capacity requirements that exceed what the existing system can serve, or reliability concerns as drives age. At a 4-year refresh cycle, the annual amortised hardware cost for a Rs.20 lakh system is Rs.5 lakh/year.
Power and cooling: A 100 TB storage system with associated networking draws roughly 2–3 kW continuously. In a self-managed server room, power at commercial Indian rates (approximately Rs.8–10/kWh in most metros) costs Rs.14,000–22,000 per month, or Rs.1.7–2.6 lakh per year. Cooling to maintain the room at appropriate temperatures for electronic equipment adds another 30–50% to the power cost.
Facility cost: If the storage lives in a dedicated server room within your office, allocate the proportionate facility cost — rent, maintenance, security for the server room square footage. In a Bangalore or Mumbai office, server room space costs Rs.5,000–15,000 per square foot per year. A 200 square foot server room is Rs.10–30 lakh per year in facility cost.
IT staff time: Someone on your team manages the storage infrastructure — firmware updates, drive replacements, capacity monitoring, backup verification, incident response. Conservatively, one-quarter of a mid-level IT engineer's time goes to storage infrastructure management. At a total compensation of Rs.12–18 lakh per year for that role, the storage management allocation is Rs.3–4.5 lakh per year.
Backup infrastructure: On-premise primary storage needs on-premise backup storage, or off-site backup cloud storage, or both. The backup infrastructure is an additional cost category.
Unplanned downtime: On-premise storage systems fail. A RAID rebuild after a drive failure takes hours. A controller failure may take days to resolve if replacement parts are not on hand. Each hour of storage downtime has a business cost that is difficult to quantify but is real.
The Full On-Premise TCO at 100 TB
Putting the numbers together for a 100 TB active storage deployment in a mid-size Indian business:
Hardware amortisation at 4-year refresh: Rs.5 lakh/year. Power and cooling: Rs.2.5–4 lakh/year. Facility cost (proportionate): Rs.2–8 lakh/year. IT staff time allocation: Rs.3–4.5 lakh/year. Backup infrastructure: Rs.1–3 lakh/year.
Total annual on-premise TCO: Rs.13.5–24.5 lakh per year, depending on facility and staffing costs. Per GB per month: approximately Rs.1.12–2.04/GB-month on the storage cost alone, before accounting for egress costs to deliver data to users or to external systems.
This does not include the cost of the capital tied up in hardware that could otherwise be deployed in the business, or the opportunity cost of IT staff time spent on infrastructure management rather than product development.
The IBEE Cloud Storage Cost at 100 TB
IBEE charges Rs.1.50/GB-month for storage. At 100 TB, that is Rs.1.54 lakh per month, or Rs.18.4 lakh per year.
Egress of data to internet at Rs.2/GB — this is an additional cost that on-premise storage also incurs (as internet bandwidth from your facility), but it is more visible on the cloud bill.
There are no hardware costs, no refresh cycles, no power and cooling costs, no facility allocation, and no storage-specific IT staff time. IBEE's 24/7 India-based support handles infrastructure incidents. Capacity scales without a procurement cycle.
Where On-Premise Wins
For large-scale cold storage with high data volume and minimal egress requirements — bulk media archives, legal record repositories, regulatory data warehouses — on-premise can be cost-competitive when the facility and power costs are already absorbed by other infrastructure, and when the data is infrequently accessed (eliminating meaningful egress costs).
On-premise also wins when data cannot leave your facility for regulatory or security reasons. For certain government, defence, or highly classified data categories, air-gapped on-premise storage is not a cost decision — it is a compliance requirement. IBEE cannot serve those use cases by definition.
Where Cloud Storage Wins
For active storage that serves users and applications — where data is regularly read, written, and delivered — cloud storage wins on every dimension except the per-GB storage price for very large, cold datasets.
Cloud storage scales elastically without procurement cycles. You do not provision capacity today for traffic you hope to have in three years. You pay for what you use, and capacity grows with your business rather than ahead of it.
Cloud storage eliminates hardware refresh risk. There is no Rs.20 lakh refresh cycle in year 4. The capital is not committed. The operational risk of hardware failure is absorbed by IBEE's infrastructure team rather than your IT staff.
Cloud storage provides documented uptime SLAs. IBEE's Tier 4 SLA of 99.995% is a level of reliability that self-managed on-premise infrastructure, without Tier 4 data centre certification, cannot match without a significantly higher infrastructure investment.
The Break-Even Analysis
For a 100 TB active storage deployment, the cloud-versus-on-premise break-even depends on the business's facility and staffing situation. In most Indian mid-size businesses, the full on-premise TCO (Rs.13.5–24.5 lakh/year) is comparable to or higher than IBEE cloud storage costs (Rs.18.4 lakh/year for pure storage, plus egress).
For businesses with already-amortised facility costs and low-cost power, on-premise may be marginally cheaper on a pure cost basis. The hidden costs that tip the analysis toward cloud are the operational complexity, hardware refresh capital, and the opportunity cost of IT staff time.
For growing businesses where storage requirements are increasing year over year, cloud storage's pay-as-you-grow model eliminates the capital risk of over-provisioning hardware for anticipated future growth that may not materialise on schedule.
Migration Path From On-Premise to IBEE
For businesses with existing on-premise storage that are evaluating a migration, IBEE's full S3 API compatibility means migration tools like rclone work directly. Copy data from your on-premise NAS to IBEE buckets using rclone sync. Validate the copy. Update application configuration to point at IBEE. Decommission the on-premise system at your own pace.
