𝘞𝘩𝘢𝘵 𝘪𝘴 𝘪𝘵?

A Landing Zone is a pre-configured, secure, and compliant foundation to host cloud workloads. Think of it as the blueprint that defines your organization’s cloud governance.

𝘞𝘩𝘺 𝘪𝘵 𝘮𝘢𝘵𝘵𝘦𝘳𝘴:

It sets guardrails for networking, security, identity, and compliance — all before a single workload is deployed.

𝘛𝘺𝘱𝘪𝘤𝘢𝘭 𝘤𝘰𝘮𝘱𝘰𝘯𝘦𝘯𝘵𝘴:

VPCs/VNets & subnets

IAM / RBAC

Shared services (DNS, Bastion, etc.)

Logging & monitoring

Policies & compliance rules

The Target Zone is where actual business workloads are deployed — web apps, databases, APIs, etc.

𝘞𝘩𝘺 𝘪𝘵 𝘮𝘢𝘵𝘵𝘦𝘳𝘴:

It leverages the Landing Zone’s foundation while delivering real value through business-critical services.

𝘛𝘺𝘱𝘪𝘤𝘢𝘭 𝘤𝘰𝘮𝘱𝘰𝘯𝘦𝘯𝘵𝘴:

App servers (EKS, AKS, EC2, App Services)

Databases (RDS, Azure SQL)

Storage (S3, Blob)

App-specific IAM

CI/CD deployment pipelines
