An AWS foundation that scales with order
We design and implement the AWS multi-account Landing Zone with Control Tower, Organizations, IAM, security baseline, networking and guardrails. Your platform is ready to grow without accumulating technical debt or operational risks.
When an enterprise starts on AWS without a well-designed foundation, problems appear months later: scattered accounts no one controls, costs that explode without traceability, accesses without policy, inconsistent networks and compliance that requires post-hoc remediation. Caleidos designs and implements the AWS Landing Zone from day 1 with AWS Control Tower as the core, AWS Organizations multi-account, security baseline (CIS/AWS), IAM with least-privilege principle, network standard (VPC patterns, Transit Gateway, hybrid connectivity), preventive and detective guardrails, and governance observability. The MAP Mobilize phase executes this foundation, but we also implement it as a standalone service for clients already on AWS who need to reorder their house.
What you get with Caleidos
Multi-account governed
AWS Organizations account structure by environment, function and business unit. Isolation, transparent billing and consistent guardrails from day one.
AWS Control Tower as core
Control Tower automates account creation, baseline application and guardrail enforcement. Fast implementation with official AWS best practices.
Security and compliance baseline
IAM with least-privilege, AWS SSO, encryption by default, AWS Config with conformance packs (CIS, PCI, HIPAA, SBS). Auditable compliance from day 1.
Standard networking
Reusable VPC patterns, Transit Gateway for inter-account connectivity, on-premise integration (Direct Connect or VPN), centralized DNS with Route 53 Resolver.
How we work
Discovery and blueprint
We map the context: existing accounts, regulatory constraints, organizational model, on-premise integrations. Output: business-aligned Landing Zone blueprint.
Implementation with Control Tower
AWS Organizations setup, Control Tower deployment, OU (Organizational Units) definition, core account creation (logging, audit, security) and automated account vending.
Security and compliance baseline
IAM Identity Center, SSO federation, password policies, MFA enforced, AWS Config rules, AWS Security Hub, GuardDuty, conformance packs by applicable regulatory framework.
Networking and connectivity
VPC patterns by workload, Transit Gateway, peering, hybrid connectivity, centralized DNS and VPC endpoints for private services.
Operation and handoff
Documentation, runbooks, team training and handoff to [Caleidos Lens©](/en/services/caleidos-lens) for continuous operation. The foundation stays alive — not a closed project.
Landing Zone implementations
Multi-account governed in 4-6 weeks
Design and implementation of AWS Landing Zone for regulated and mid-market enterprises: Control Tower, multi-account Organizations, CIS/SBS security baseline, standard networking and governance observability.

What we get asked the most
What exactly is an AWS Landing Zone?
It's the set of configurations, accounts, networks, policies and guardrails forming the foundation upon which all your AWS workloads are deployed. It's the difference between having "an AWS account" and having an "enterprise AWS platform". Done well from day 1, prevents months of subsequent remediation work.
Why AWS Control Tower instead of building it manually?
Control Tower is the official AWS service that automates Landing Zone creation following validated best practices. Building manually with CloudFormation or Terraform is possible but requires maintaining all the code and updating it as AWS evolves the standards. Control Tower is managed by AWS and stays updated.
How long does Landing Zone implementation take?
For a mid-market enterprise: 4-6 weeks for the complete foundation (Control Tower + 3-5 OUs + core accounts + security baseline + basic networking). Companies with strict regulation or many legacy accounts to migrate may take 8-12 weeks.
Can I implement a Landing Zone if I already have disorderly AWS accounts?
Yes, it's one of the typical cases. We do an account onboarding plan: existing accounts are progressively brought under Control Tower, workloads are migrated to the new structure by waves, and legacy accounts are decommissioned. No production disruption.
How does it relate to AWS migration (MAP)?
Cloud Foundations is the Mobilize phase of the AWS Migration Acceleration Program. If your organization is migrating to AWS, this is the first wave of work. For clients already on AWS, we offer it as a standalone service to reorder the foundation. Learn more at /en/services/migracion-aws.
Is regulatory compliance (SBS, PCI, ISO) included?
Yes. The baseline applies AWS Config conformance packs specific by regulation, defines IAM and encryption policies according to framework, configures centralized logging for auditing and leaves the platform ready for formal audits. For Peru FSI we work with SBS Resolution N° 504-2021 (Cybersecurity) and N° 502-2017 (Outsourcing).
