Security, How To Guides, Resources

15 min read

As organizations increasingly adopt multi-cloud strategies to avoid vendor lock-in and optimize costs, implementing secure observability across diverse cloud environments becomes a critical challenge. Traditional monitoring approaches often fall short in multi-cloud scenarios, where security requirements vary between providers and data sovereignty concerns add complexity. Zero-trust observability represents the gold standard for secure telemetry collection in multi-cloud environments, ensuring that all monitoring traffic is treated as potentially hostile while maintaining comprehensive visibility. In this comprehensive guide, we'll explore how to implement zero-trust observability across AWS, Azure, and GCP using OpenTelemetry, with detailed security controls and integration strategies for Logit.io.

Understanding Zero-Trust Observability in Multi-Cloud Context

Zero-trust observability in multi-cloud environments extends the principles of zero-trust security architecture to encompass all aspects of telemetry collection, processing, and analysis across multiple cloud providers. Unlike traditional monitoring approaches that rely on network-based security, zero-trust observability implements identity-based authentication, encryption at every layer, and continuous verification of all monitoring components.

The core principles of zero-trust observability in multi-cloud environments include:

  • Identity-Based Authentication: Every component in the monitoring pipeline must authenticate using strong identity verification
  • Encryption in Transit and at Rest: All telemetry data must be encrypted during transmission and storage
  • Least Privilege Access: Monitoring components should have minimal necessary permissions
  • Continuous Verification: Ongoing validation of monitoring infrastructure security posture
  • Audit Logging: Comprehensive logging of all monitoring activities and access patterns

Multi-cloud environments introduce unique challenges for zero-trust observability, including different security models across providers, varying compliance requirements, and the need to maintain consistent security controls across diverse infrastructure. Each cloud provider has different security capabilities, authentication mechanisms, and network architectures that must be accommodated in a unified zero-trust strategy.

Multi-Cloud Security Architecture Design

Cross-Cloud Identity Federation

Implementing zero-trust observability across multiple cloud providers requires a robust identity federation strategy that can authenticate monitoring components regardless of their location. This involves establishing trust relationships between different cloud providers and implementing consistent authentication mechanisms.

For AWS, Azure, and GCP environments, implement identity federation using:

  • AWS IAM Identity Center: Centralized identity management with SAML 2.0 federation
  • Azure Active Directory: Enterprise identity services with cross-cloud synchronization
  • Google Cloud Identity: Unified identity management with SSO capabilities
  • OpenID Connect: Standardized authentication protocol across all providers

Configure cross-cloud identity federation to enable seamless authentication for monitoring components:

apiVersion: v1

  name: identity-federation-config
data:
  federation.yaml: |
    identity_providers:
