How We Enabled Full AWS Infrastructure Ownership and Cost Transparency For CHMI

Limited ownership, cost inefficiencies, and lack of operational control

The client's AWS environment was hosted under a third-party account, limiting direct ownership and visibility into infrastructure and operations. This restricted control over governance policies, security configurations, and day-to-day decision-making.

As infrastructure usage increased, costs became high and unpredictable, with no structured mechanism to monitor or optimize cloud spend. The absence of a FinOps approach made it difficult to establish cost accountability and long-term efficiency.

In addition, governance practices were inconsistent, with fragmented access controls and no centralized compliance guardrails in place. Operationally, full dependency on external teams led to slow incident response and delays in executing changes.

AWS managed services model with governance, security, and operational control

zeb designed and implemented a structured AWS Managed Services framework, enabling full ownership, improved governance, and continuous operational support across the environment.

• Environment Ownership and Governance: Migrated workloads into a fully CHMI-owned AWS account using AMI snapshot cross-account transfer. Established a multi-account landing zone using AWS Control Tower to enforce governance at scale. Implemented Service Control Policies (SCPs) and AWS Config to ensure compliance monitoring, along with AWS IAM Identity Center to provide centralized SSO and enforce least-privilege access.
• Infrastructure Modernization and Resilience: Deployed core workloads on Amazon EC2 with Amazon WorkSpaces enabling secure remote access. Strengthened data protection by implementing AWS KMS encryption across EBS and RDS. Enabled cross-region Backup replication to support disaster recovery, business continuity, and maintain high availability across environments.
• Managed Operations and Continuous Optimization: Established 8×5 managed operations with 24×7 P1 incident support, backed by a 15-minute response SLA and defined escalation paths. Implemented and fully managed ServiceNow ITSM by zeb to streamline incident and change management processes. Enabled continuous monitoring using GuardDuty and Security Hub to ensure critical vulnerabilities (CVEs) are addressed within 48 hours.

Introduced enterprise observability across infrastructure, security, and cost layers using AWS-native monitoring and FinOps reporting, enabling real-time visibility into system health, compliance posture, and cost behavior across the environment. Ongoing optimization was driven through monthly FinOps reviews, Compute Savings Plans management, and AWS Well-Architected reviews.

Improving control, cost efficiency, and operational resilience

The AWS Managed Services implementation provided a structured and controlled cloud environment aligned with operational and financial goals.

• Full Infrastructure Ownership: Transitioning to a CHMI-owned AWS account provided complete visibility and control over infrastructure and operations.
• Improved Cost Efficiency: Structured FinOps practices, Savings Plans, and rightsizing enabled predictable cloud spend with full visibility for the first time.
• Stronger Governance:Centralized identity management, Control Tower guardrails, SCP enforcement, and AWS Config monitoring established a consistent governance framework.
• Enhanced Reliability and Availability: 24×7 monitoring, SLA-driven incident response, and proactive issue detection improved system reliability and ensured high availability.
• Strengthened Security Posture: Continuous threat detection through GuardDuty, insights from Security Hub, encryption across all layers, and automated patching improved overall security and risk management.

Modern cloud environments require strong governance, continuous monitoring, and cost-efficient operations. zeb helps organizations establish fully managed AWS environments with structured governance, reliable operations, and ongoing optimization.
