Revision summary
Cloud hosting cuts idle hardware cost and makes scale, patching, and disaster recovery easier for ordinary government work. In-house hosting still fits air-gapped and highly classified systems. Cloud risks are multi-tenancy, key control, data location, provider insiders, and lock-in. In-house risks are unpatched boxes, weak rooms, and no second copy. Use GI Cloud with government keys for most data; keep secrets on dedicated government infrastructure.
Model answer
Copper italics in this answer — like this — are the key facts. Each one is unpacked in the Facts & figures rail.
Introduction
Government business now lives on email, databases, citizen portals, and files. In-house hosting means servers in a department’s own room. Cloud hosting means shared, on-demand computing from a provider — in India, including GI Cloud (MeghRaj) and National Informatics Centre clouds. The choice is about cost, speed, and who holds the keys, not about fashion.
Body
Advantages of cloud hosting
- Departments pay for use, not for a full hall of idle machines, which cuts capital cost and the wait for new hardware.
- Scale can rise on a filing day or a disaster portal without a two-year purchase file.
- Patches, backups, and failover can be professional if the provider is audited; many small departments cannot hire that skill in-house.
- Disaster recovery in a second region is cheaper on cloud than building two full data centres for every ministry.
- Shared platforms (identity, storage, logs) make common security baselines easier than fifty different server rooms.
- Staff can focus on the scheme, not on changing tapes, if the contract is honest.
Advantages of in-house hosting
- The department sees the rack, controls physical access, and can keep a classified system off the public internet.
- Air-gapped or highly sensitive workloads (some intelligence, some nuclear and defence design) may still need a private hall.
- There is no foreign or private vendor in the path if the machine is truly departmental — though NIC already is a shared public host.
- Legacy line-of-business software that cannot move may have to stay on a known box for a time.
Security implications of cloud
- Multi-tenancy means a neighbour’s bug or a bad hypervisor could, in a worst case, leak data; isolation and encryption at rest and in transit are mandatory.
- Who holds the encryption keys decides whether a provider, or a foreign parent company, can be compelled to open a government file.
- Data location: citizen data on a server outside India raises sovereignty, MLAT delay, and Official Secrets problems; empanelled Indian or NIC clouds reduce that risk.
- Insider and admin abuse at the provider is a new threat class; privileged-access logs and government key management are the reply.
- Vendor lock-in and outage: a failed cloud can freeze a welfare portal nationwide; in-house failure is usually local but often worse patched.
- Lawful intercept and audit: contracts must state logs, CERT-In reporting, and the right to inspect, or the cloud is a black box.
Security implications of in-house machines
- Physical control is real; patch lag, weak passwords, and a single unguarded room are also real, and they have caused many Indian leaks.
- A fire, flood, or theft in one building can wipe the only copy if backup is a cupboard.
- Shadow IT (a tower under a desk) is common when procurement is slow; that is often less secure than a governed cloud.
Way forward
- Classify data: public and ordinary personal data on empanelled GI Cloud; secret and above on dedicated government cloud or in-house with NIC-grade ops.
- Use MeghRaj, encryption with government-held keys, and Indian legal jurisdiction for citizen databases.
- Ban unapproved public foreign clouds for official files; allow them only for open websites if policy says so.
- Train a small cloud security cadre and run annual drills with CERT-In.

Conclusion
Cloud hosting gives government elasticity, professional backup, and lower idle capital. In-house hosting gives physical control for the most secret work. Security is not automatic in either room: cloud needs keys, location, and contracts; in-house needs patches and backups. A classified split on MeghRaj-class clouds is safer than every ministry running its own forgotten tower.

-
Is cloud always less secure than a department server?
No. A locked, patched, backed-up cloud can beat an unlocked office tower. Security follows keys, patches, and people, not the slogan ‘our own machine’.
-
Should all government data go to a US public cloud?
Ordinary open sites might. Citizen databases and secrets should stay on empanelled Indian or NIC clouds under Indian jurisdiction.

What are the challenges to solid waste management in India? Discuss the governmental policy framework on solid waste management. Discuss the success/failure cases of Delhi and Indore cities highlighting the salient features of their solid waste management initiatives.
Indian Economy
• Rapid urbanization has made solid waste management a critical environmental and public health crisis in India. • Key challenges include lack of source segregation, inadequate processing infrastructure, reliance on unprotected informal workers, and financially weak urban local bodies. • The policy framework relies on the SWM Rules 2016, Swachh Bharat Mission (Urban), and Plastic Waste Management Rules 2016. • Indore succeeded through 100% source segregation, zero dump-site remediation, and strict enforcement with digital monitoring. • Delhi failed due to overloaded legacy landfills (Ghazipur, Bhalswa), lack of decentralization, and fragmented municipal governance. • A successful transition requires moving to a circular economy focused on source segregation, decentralized processing, and polluter accountability.

What is Agentic Artificial Intelligence (AI)? Explain its working. Describe its applications with suitable examples. Discuss the advantages, risks and challenges associated with agentic AI systems.
Indian Economy
Agentic Artificial Intelligence represents an advanced paradigm where AI systems operate with autonomy, setting goals and executing complex workflows without constant human prompts. Unlike traditional generative AI that merely responds to queries, agentic AI uses perception, planning, memory, and tool-use to achieve multi-step objectives. Its applications span across autonomous software engineering, supply chain optimization, and automated financial trading. While offering massive productivity gains and dynamic problem-solving, these systems pose significant risks including lack of transparency, alignment failures, security vulnerabilities, and ethical dilemmas. Governance frameworks and robust guardrails are essential to harness their potential safely.
