5 - Cloud Landing Zone Lifecycle

In the context of a cloud landing zone, “Day 0,” “Day 1,” and “Day 2” refer to specific phases in the lifecycle of establishing and managing the landing zone within a cloud environment. Here’s how these terms apply:

ROT - cloud landing zone lifecycle design -day 0 - day zero


Cloud Landing Zone Lifecycle

Design (Day 0)
  • Planning is crucial in this stage. Organizations must strategize and establish requirements such as security and compliance, workload management, performance, identity and access management, networking, high availability, and cost optimization. By creating a roadmap, you can avoid potential challenges in your cloud journey.

Design (Day 0) Explained

As you begin your adventure into the cloud, it’s important to plan and strategize your landing zones carefully. These landing zones act as the first step and crucial base of your cloud setup.

Let’s explore four important areas that a well-designed landing zone should cover:

Security and Compliance

  • It’s important to streamline your security measures, monitoring practices, and logging systems. By centralizing these aspects, you can ensure that company-wide compliance requirements and data residency policies are adhered to. This approach enables the establishment of a baseline level of compliance across various tenants or environments.

Standardized Tenancy

  • To promote consistency and efficiency, it’s beneficial to enforce tagging policies consistently across multiple cloud tenants. Additionally, offering standardized tenants tailored to different security profiles (such as development, staging, and production environments) helps maintain organization and clarity.

Identity and Access Management (IAM)

  • Implementing the principle of least privilege is key to enhancing security. This involves defining specific roles and access policies to restrict access to only what is necessary for each user. It’s also essential to establish uniform user ID configurations and password standards across all tenants.


  • Establishing foundational networking configurations is vital for smooth operations. This includes setting up Infrastructure as a Service (IaaS) network configurations, implementing firewalls, and configuring other basic networking parameters according to your requirements. Having these elements in place ensures a robust networking infrastructure within your cloud environment.
Cloud Landing Zone Lifecycle Deployment (Day 1)

Deployment (Day 1)
  • Once the design phase is complete, deployment begins. Different cloud service providers (CSPs) handle landing zones differently based on their cloud adoption frameworks. Choose a cloud landing zone service from top vendors like AWS, Azure, or Google Cloud Platform (GCP) that aligns with your business needs.

Deployment (Day 1) Explained

During the initial deployment phase, known as Day 1, the focus is on tailoring and rolling out a landing zone based on the design and specifications outlined during the planning phase, Day 0. Different public cloud service providers approach the implementation of landing zones in varying ways.

Let’s examine the approaches of the three major cloud service providers:

Microsoft Azure

  • Within Microsoft’s cloud platform, the Cloud Adoption Framework incorporates the concept of landing zones. A key tool for this is Azure blueprints, which allows users to select and configure migration landing zone blueprints within Azure to establish their cloud environments. Alternatively, third-party services like Terraform can also be utilized.

Amazon Web Services (AWS)

  • AWS offers a solution simply known as AWS Landing Zone. This solution includes a pre-configured security baseline that sets up AWS services such as CloudTrail, GuardDuty, and Landing Zone Notifications. Additionally, it automates the setup of a landing zone environment, expediting cloud migrations. Depending on specific needs, AWS provides CloudFormation Templates for customizing and standardizing service or application architectures.

Google Cloud Platform (GCP)

  • GCP employs the Google Deployment Manager for writing flexible template and configuration files. Users can utilize a declarative format using YAML, or Python and Jinja2 templates, to configure their deployments effectively.
