Cloud Security Architecture & SLA Management

Turn cloud service commitments into an architecture and responsibility matrix. We review identity, data protection, recovery and monitoring boundaries, then define measurable SLA criteria, evidence sources and escalation routes with your teams.

Our engagement produces a service-specific responsibility matrix, prioritised architecture changes and an SLA measurement plan for implementation and review.

7 QUESTIONS, BRIEFLY ANSWERED

Frequently asked questions about Cloud Security Architecture & SLA Management

What does a cloud security architecture include and why are default configurations insufficient?

A cloud security architecture connects identities, networks, data, workloads and operational controls. Evaluate each service configuration against the workload risks and applicable obligations. Provider defaults are a starting point to assess, not proof that the workload is protected. The review should identify required customer controls and how they will be tested.

How does the shared responsibility model work and where is the boundary between cloud provider and enterprise?

Responsibility depends on the service model, provider terms and configuration. For each service, document who configures access, protects data, collects logs, performs recovery and responds to incidents. Include customer duties identified in provider assurance reports. Test the boundaries with an incident or recovery scenario and assign unresolved responsibilities explicitly.

Which SLA metrics are business-critical for cloud services and how are they monitored?

Start with the supported business service. Define availability measurement windows, exclusions, response and restoration commitments, measurement sources and escalation contacts. RTO and RPO are recovery objectives whose achievement needs exercise evidence; a dashboard alone cannot demonstrate recovery capability. Review observed performance alongside contractual service credits and customer recovery dependencies.

How do you integrate Zero Trust principles into an existing cloud security architecture?

Zero Trust follows the principle of 'never trust, always verify' — every access request is authenticated and authorised regardless of network location. Integration starts with an inventory of all identities, devices and data flows. Then micro-segmentation, context-based access control and continuous verification are implemented. In existing cloud environments, this happens in phases: first identity-centric controls, then network segmentation, finally workload protection. ADVISORI guides this process from architecture planning to implementation with measurable milestones.

What regulatory requirements apply to cloud security architectures in the financial sector?

Determine the entity and service scope first. DORA has applied since January 2025 and covers ICT risk, resilience testing and ICT third-party risk. Institutions subject to its ICT risk-management requirements are excluded from BAIT. Translate the applicable obligations into service-specific controls, contracts and evidence; do not stack every historical regulatory framework onto each cloud service.

How do you manage SLAs effectively in multi-cloud environments with different providers?

Multi-cloud environments require a unified SLA governance framework that harmonises provider-specific differences. ADVISORI develops standardised metrics that are comparable across AWS, Azure and GCP. The framework includes vendor scorecards, automated performance reports, escalation paths and contractual safeguards for service outages. The crucial factor is correlating technical SLA metrics with business impact — 15 minutes of payment service downtime has very different consequences than the same outage on an internal reporting tool.

What does a professional cloud security architecture cost and when does the investment pay off?

Estimate effort from the number of workloads and providers, existing architecture documentation, contract access and the depth of testing. Agree deliverables and dependencies before fixing a schedule. Assess value through measurable control gaps closed, reduced manual work and demonstrated recovery capability. An industry-wide breach-cost average does not establish the return on this project.
