How governments adopt the cloud for national security and defense in Asia-Pacific

Governments in the Asia-Pacific region are modernizing their national security operations to maintain strategic advantage in an increasingly complex threat environment. Cloud adoption offers them unprecedented opportunities for innovation, operational effectiveness, and resilience.

As noted in the International Institute for Strategic Studies (IISS) paper, Cloud Adoption for National-security and Defence Purposes: Four Case Studies from the Asia-Pacific, which was supported by Amazon Web Services (AWS), decision advantage through data mastery is a compelling driver of cloud adoption.

Researchers from the IISS Cyber Power and Future Conflict program looked at approaches to cloud adoption by Japan, the Philippines, Singapore, and Thailand and considered implications and recommendations for other governments.

Why national security and defense agencies are embracing cloud technology

National security and defense (NS&D) organizations need to process vast quantities of data, integrate operations across multiple domains, and respond to rapidly evolving threats. Traditional IT infrastructure such as on-premises data centers struggle to elastically scale and integrate multidomain data at the pace required in today’s threat environment.

Modern defense operations generate enormous volumes of intelligence from satellites, sensors, communications intercepts, and open sources. Cloud technology can enable advanced threat detection by using artificial intelligence and machine learning (AI/ML) capabilities for signal prioritization and anomaly detection. It can also support controlled, policy-driven intelligence sharing between allied agencies.

Cloud architecture distributes data across multiple locations, reducing vulnerability to both physical attacks and cyber incidents while enabling distributed command and control capabilities. Cloud infrastructure and services are highly scalable and highly available, meaning government agencies can acquire, process, and analyze data at an unprecedented speed and scale.

The cloud is an on-demand service that provides dynamic scalability without requiring upfront capital expenditure on physical infrastructure. Agencies benefit from cloud providers like AWS investing in cloud security maintenance and emerging technologies like AI. Organizations responsible for national security and defense can instead focus their resources on mission objectives while relying on defense-in-depth security controls aligned to NS&D requirements.

Four national approaches to cloud adoption

The IISS paper describes how Japan, the Philippines, Singapore, and Thailand tailor cloud adoption to their unique security requirements and digital maturity:

1. Japan is modernizing its NS&D strategy with hybrid cloud environments, focusing on cross-domain integration and alliance interoperability.
2. The Philippines is in the early stages of cloud adoption across the government, aiming to enhance interservice coordination and secure cloud management through its Digital Transformation Strategy.
3. Singapore is developing a secure hybrid cloud solution for defense, linking military readiness with national resilience through its Smart Nation and Total Defence initiatives.
4. Thailand is modernizing its government digital infrastructure by using AWS for policing solutions while building internal governance capacity for sensitive data protection.

Strategic recommendations for NS&D leaders

The IISS report offers guidance for defense and national security leaders embarking on cloud adoption journeys:

• Redefine sovereignty-assured governance with transparent control mechanisms rather than technological isolation. Experience demonstrates that cloud services can equip governments to maintain effective governance, security, and control over their critical and sensitive data. Governments can use global cloud providers while retaining full visibility and lawful control through technical and governance arrangements including data classification, encryption, and strong access controls. This calibrated approach allows for appropriate levels of protection for different data types. It balances sovereignty and resilience considerations, maximizing the benefits of commercial innovation and maintaining security for the most sensitive operations.
• Build institutional maturity and domestic expertise. Technical solutions alone can’t bring about successful cloud adoption. Governments must develop the appropriate organizational depth, regulatory clarity, and technical capabilities. For example, they can establish dedicated and resourced cloud adoption teams to drive implementation. Investment in domestic technical expertise strengthens strategic autonomy and effective oversight.
• Prioritize securely sharing data with allies. We recommend that cloud solutions are designed with international interoperability in mind, facilitating rapid data exchange with trusted partners. This capability has become essential for coalition operations and intelligence sharing. Joint approaches across security agencies can break down silos between military branches and intelligence organizations, creating more effective whole-of-government responses to threats.
• Design for resilience and operational continuity. Cloud architecture must support operations continuing during crises, including potential relocation of critical data if necessary. Core security controls including encryption, multi-factor authentication (MFA), and zero trust principles serve as the security foundation for all systems, with specialized additional controls implemented based on data sensitivity and classification.

Access innovation and maintain control for national security

For NS&D leaders, cloud adoption is the way to maintain a strategic advantage in an increasingly contested global information environment. Success requires using global expertise and technical capabilities, engineering resilience, and boosting domestic institutional capacity. Governments that master this balance are positioned to protect their citizens and interests in the digital age.
