A Path Through the Cloud: Saving Privatbank's It Operations During the War in Ukraine Custom Case Solution & Analysis

1. Evidence Brief (Case Researcher)

Financial Metrics:

• PrivatBank serves 18 million retail clients and 1.1 million corporate clients (Intro).
• Bank handles 30% of all retail transactions in Ukraine (Intro).
• Operating scale: 200 applications and 3,500 servers hosted on-premises (Paragraph 4).

Operational Facts:

• Migration scope: Move critical banking infrastructure to the cloud (AWS) to avoid destruction by Russian missile strikes (Paragraph 6).
• Timeline: Migration completed in 45 days during active warfare (Paragraph 12).
• Technical hurdles: Massive data volume (petabytes), legacy architecture, and strict regulatory requirements for data sovereignty within Ukraine (Paragraph 9).

Stakeholder Positions:

• Mariia Martynenko (Head of IT Infrastructure): Leads the migration project; focuses on speed and survival.
• National Bank of Ukraine (NBU): Initially restricted cloud usage; required emergency regulatory override due to war (Paragraph 11).

Information Gaps:

• Specific cost breakdown of AWS migration versus on-prem maintenance.
• Detailed latency impact on core banking applications post-migration.

2. Strategic Analysis (Strategic Analyst)

Core Strategic Question: How to maintain business continuity and national financial stability when physical infrastructure is a primary target for military destruction?

Structural Analysis:

• Risk Concentration: The bank’s reliance on physical data centers created a single point of failure that the enemy could exploit.
• Regulatory Constraints: The pre-war legal framework prioritized data localization, which became a liability under invasion conditions.

Strategic Options:

• Option 1: Decentralized On-Premise Resilience. Build hardened, hidden bunkers across the country. Trade-off: High capital cost, slow deployment, still vulnerable to targeted strikes.
• Option 2: Cloud-First Migration (Selected). Shift all critical operations to global cloud providers. Trade-off: High complexity, regulatory friction, dependency on international infrastructure.
• Option 3: Hybrid Maintenance. Keep core ledgers local, move non-critical apps to cloud. Trade-off: Maintains systemic risk; does not solve the destruction threat.

Preliminary Recommendation: Option 2. In a war scenario, the speed of cloud deployment outweighs the long-term cost and regulatory hurdles.

3. Implementation Roadmap (Implementation Specialist)

Critical Path:

• Phase 1: Emergency regulatory lobbying for cloud data storage (Days 1-7).
• Phase 2: Data pipeline establishment and initial synchronization (Days 8-20).
• Phase 3: Failover testing and final cut-over (Days 21-45).

Key Constraints:

• Connectivity: Reliance on unstable internet infrastructure during active bombardment.
• Talent: IT staff working from shelters under extreme psychological stress.

Risk-Adjusted Strategy:

• Implement automated failover protocols.
• Distribute IT teams geographically to ensure no single strike compromises the entire engineering capability.

4. Executive Review and BLUF (Executive Critic)

BLUF: PrivatBank survival was not a technology project; it was an existential necessity. The decision to move to the cloud was the only viable path to preserve the national financial system. The project succeeded because the team prioritized functional survival over perfection. Future resilience depends on establishing a permanent, multi-cloud architecture that treats regional instability as a standard operational parameter rather than an emergency.

Dangerous Assumption: The assumption that international cloud providers will remain neutral and accessible indefinitely. Any shift in geopolitical stance could render this infrastructure inaccessible.

Unaddressed Risks:

• Data Sovereignty: Future legal challenges regarding where data resided during the crisis.
• Cyber Warfare: The cloud environment provides a larger, more accessible surface for state-sponsored cyber-attacks compared to air-gapped legacy systems.

Unconsidered Alternative: Establishing a sovereign data vault in a neighboring neutral country, bypassing standard global cloud providers to ensure total control over data integrity.

Verdict: APPROVED FOR LEADERSHIP REVIEW.
