12. You Need A “Landing Zone”
• A configurable, secure, scalable, multi-tenant GCP environment based on
GCP best practices.
• A starting point for net new development and experimentation
• A starting point for migrating applications
• An environment that allows for iteration and extension over time
• An environment that provides enough flexibility and scale up and down as
per business needs

13. Pillars of Landing Zone

Hierarchy

15. Resource Hierarchy

16. Resource Hierarchy

17. Resource Hierarchy - Organization
• Root node of the Resource Hierarchy
• Highest level in the resource hierarchy within GCP Landing Zone.
• Top-level container that owns and controls resources
• Logical and administrative boundaries for managing and organizing resources

18. Resource Hierarchy - Folders
• Folders are a way to further organize resources
• Grouping projects and folders enable granular access control and resource
management.
• Offers flexible structure to align with organizational needs

19. Resource Hierarchy - Projects
● Building blocks for organizing and managing application resources.
● Have unique resources like compute, storage, databases, and networking
configurations.
● Enable isolation and encapsulation for independent management, billing,
and access control.

20. Resource Hierarchy - Resources
● Can be grouped together based on their purpose or ownership.
● Can be given different levels of access control.
● Can be monitored and billed separately.
● Easily moved between projects.

21. Resource Hierarchy - Organization Structure

22. Identity Provisioning

23. Identity
Provisioning
Google
Groups
AD Connect
Authorization
MFA

24. Identity Provisioning
• Set up Azure AD to automatically
provision users and, optionally,
groups to Cloud Identity or Google
Workspace.
• Configure single sign-on
• Create a Google Identity
• Enable MFA

25. Networking

26. Shared VPC
Networking
Service
Project
Host
Project

27. Shared VPC
Host Project: contains one or more Shared VPC
networks. A Shared VPC Admin must first enable a
project as a host project. After that, a Shared VPC
Admin can attach one or more service projects to
it.
Service Project: A service project is any project
that has been attached to a host project by a
Shared VPC Admin. This attachment allows it to
participate in Shared VPC. It's a common practice
to have multiple service projects operated and
administered by different dep
Note: Be it a prod/non-prod environment each &
every environment will contain a Shared VPC

28. Host Project
• Create a Host Project
• Create a VPC and Subnets
• Enable Shared VPC and Subnet Sharing
• Deploy Resources

29. Perimeter Project
• Deploy a Load Balancer
• Setup External Firewall
• Provision SSL Certificate
• Route Traffic through ALB & Firewall
• Setup Cloud Armor to protect
against DDOS attack

30. Networking

31. Connectivity With On Prem

32. Security

33. Data Security

Perimeter
Security

34. Security - Tools

35. Security - Observability (Auditing)
• GCS Log Bucket / Log Sink
exists at the org level
• It’s immutable
• You can directly run BigQuery.

36. Security - Observability (Logging/Monitoring)
• Enable Cloud Logging
• Define Log Entries
• Configure log exports
• Create log filters
• Alerts & Notifications

37. Budgets & Alerts
• Proactive Cost Control
• Granular Monitoring
• Automated Efficiency
• Seamless Integration

38. Getting Started

39. Clone The Repository
Git Repository Local Copy
PBMM compliant landing zone

40. Bootstrapping

41. Non-Prod, Prod, Combined Environments
• Create Project Folder Under Respective
Department
• Setup Various Environments
• Configure VPC and Subnets in Host Project
• Setup Shared VPC
• Attach Service Project

42. Conclusion
• GCP Landing Zone provides enterprises with a standardized and secure
foundation for deploying workloads on Google Cloud Platform.
• Enables consistent governance, security measures, cost optimization,
scalability and agility, and empowers enterprises to leverage the full
potential of Google Cloud Platform.
