Build a Secure Cloud Landing Zone

A cloud landing zone is the prepared base for your cloud: the account structure, sign-in and access, network, logging and rules that every workload is deployed into.

Without one, every team sets up accounts, access and networks its own way. A landing zone gives one secure starting point, so new projects can start sooner and audit evidence is easier to gather.

An Azure landing zone is a landing zone built on Azure subscriptions and management groups. Microsoft’s Cloud Adoption Framework guide to Azure landing zones describes two parts: a platform landing zone with shared governance, security and resources, and workload landing zones where teams deploy within the platform’s guardrails.

AWS Control Tower is the AWS service for setting up and governing a multi-account environment. The AWS Control Tower user guide describes the landing zone it builds, controls (sometimes called guardrails) and an Account Factory for creating new accounts from a template.

Guardrails are rules applied across accounts. Preventive guardrails block a setting, such as public storage, and detective guardrails report when something breaks a rule. AWS Control Tower also has proactive controls, which check resources before they are deployed.

Separate accounts or subscriptions keep problems, permissions and costs contained. A mistake in a test account stays out of production, and each team’s spend shows on its own line.

A small one, yes. Getting identity, logging and rules right is easier with five workloads than fifty. The design can start simple and grow as you add teams and accounts.

Yes. Existing accounts can be brought under central management, then rules and logging are applied to them. Workloads with clashing network ranges may need changes, which are planned in stages.

It depends on the number of accounts, clouds and office connections involved, which is why the Cloud Foundation Review sets the scope first. A first version can be built and tested before larger migrations start, then extended as teams join.

The change drifts away from the agreed design. Configuration checks report the difference, and the platform team either adds it to the code or reverses it, so the code stays the true record of the foundation.

A small, named platform team, signing in with their company identity. Workload teams get access only to their own accounts. Our page on identity and access management explains the basics.

In one central place that workload teams are not allowed to change or delete, with logging switched on in every account and region in use.

Tags record the owner, project and environment of each resource. With required tags and separate accounts, the bill can be split by team and idle resources traced to an owner.

The cloud that runs your main production workloads, since that is where gaps carry the highest risk. The same standard for identity, rules, network ranges and tags can then be applied to the second cloud.

A landing zone sets the foundation every account sits on. Our Secure Cloud Infrastructure and Workloads use case goes deeper into each application’s settings, data and threats.

Your platform or cloud team, using the design and code handed over at the end. Where ongoing support is agreed, Signisys can help run and update it.

We work with AWS and Microsoft as a Technology Partner, building landing zones with each cloud’s own tools.

The Cloud Foundation Review compares your accounts, sign-in, network, logging and rules with AWS and Azure landing zone guidance, and ranks the gaps by risk. It needs read-only access to your cloud accounts, current account and network diagrams and time with your cloud or platform lead. We walk you through the findings on a call.
