UPSC Mains 2015 GS Paper 3 Q13: model answer
Discuss the advantages and security implications of cloud hosting of servers vis-a-vis in-house machine-based hosting for government businesses.
What the question wants
Discuss the advantages and the security risks of cloud hosting compared with in-house servers for government work.
How to structure it
Compare in two columns, then a way forward.
- Meaning
- Advantages of cloud
- Security implications
- In-house trade-offs
- Balance
How to think it through
Cloud: servers run by provider (IaaS/PaaS/SaaS); MeghRaj GI Cloud 2014; MeitY empanelment of CSPs; National Data Centres (NIC). Advantages: cost, scale, faster rollout (CoWIN scaled), disaster recovery, updates, pay-per-use. Risks: data location and jurisdiction (US CLOUD Act), vendor lock-in, multi-tenancy breaches, insider access, outages, compliance; in-house: control but costly, outdated security, skills shortage (AIIMS 2022 in-house servers hit). Balance: hybrid, sovereign cloud, data classification, localisation for sensitive, CERT-In audits, encryption with own keys.
Model answer
When CoWIN had to handle crores of vaccine bookings in a few weeks in 2021, it ran on cloud capacity that could grow overnight. In November 2022, the AIIMS Delhi servers, run in-house, were hit by ransomware and the hospital went back to paper for days. Both cases show that the question is not 'cloud or not' but how safely.
Advantages of cloud hosting
- Lower cost: no big upfront spending on servers; pay as you use.
- Scale up and down quickly for peak demand.
- Faster rollout of new e-services.
- Built-in backup and disaster recovery.
- Regular security updates by the provider.
- India's MeghRaj (GI Cloud, 2014) and MeitY's empanelment of cloud providers make it easier.
Security implications of cloud
- Data location and jurisdiction: foreign laws may allow access to data stored abroad.
- Shared servers with other customers raise breach risks.
- Vendor lock-in and dependence on private firms.
- Outages that can shut many departments at once.
In-house hosting: the trade-off
- Full control over sensitive data.
- But costly, often outdated, and short of skilled staff, as AIIMS showed.
The way forward
- Classify data: keep highly sensitive data on government or sovereign cloud.
- Hybrid model for routine services.
- Encryption with government-held keys.
- CERT-In audits and its 2022 rule to report incidents within 6 hours.
Where data sits matters less than who holds the keys and who checks the locks.
Draw: A two-column table: cloud vs in-house on cost, scale, control, security and skills.
Keywords, cases and data to drop in
cloud hosting, IaaS/PaaS/SaaS, MeghRaj GI Cloud 2014, MeitY empanelment, CoWIN, AIIMS ransomware 2022, data localisation, jurisdiction, multi-tenancy, vendor lock-in, sovereign cloud, hybrid, encryption keys, CERT-In 6-hour rule.
Where most answers lose marks
- Writing only the advantages of the cloud and ignoring the security implications the question highlights.

DRDO’s indigenous AIP for Kalvari-class submarines reaches the Setting to Work Phase-2 stage
Diesel-electric submarines must come up often to run their engines and charge batteries, which can give away their position. Air Independent Propulsion (AIP) lets them stay underwater much longer.

NVS-03 launch on 30 October: can ISRO’s new satellite bring NavIC back to life?
ISRO will launch NVS-03, its third new-generation navigation satellite, on 30 October 2026, The Indian Express reported on 24 October. NavIC, India’s own GPS-like system, has not been able to give location data because only three satellites work, while positioning needs at least four. If NVS-03 works, NavIC can offer positioning again. It is a lesson in why strategic technology needs both satellites and users.
