AWS Migration & Cloud Modernization

Stop fighting your infrastructure.
Start scaling.

We plan and execute on-premises-to-cloud migrations for small and mid-sized businesses — production-ready infrastructure as code, secure deployment pipelines, and clear visibility over your new cloud from day one.

Our experience

Enterprise IT depth, focused on cloud migration for growing businesses.

CloudHorizon Advisory was founded on a 25-year bedrock of IT experience spanning the commercial sector, local municipalities, and federal government environments. Over the past five years, our practice has specialized deeply in planning and executing critical on-premises workload migrations into commercial cloud providers.

We launched CloudHorizon Advisory to solve a critical market gap: helping small-to-medium businesses seamlessly navigate the high-stakes complexity of moving legacy infrastructure to the cloud without disrupting core operations.

True cloud transformation isn't just about moving workloads — it's about maintaining absolute visibility once you arrive. That firsthand friction drove us to engineer Apex by CloudHorizon Advisory, our platform that gives stakeholders a clear, intuitive lens into their cloud topography and asset monitoring.

What we do

Enterprise cloud strategy, engineered for scale.

Web Presence & Cloud Hosting

The entry point to a cloud relationship. We build and host your website on AWS with the same automated, secure pipeline we'd use for any production workload — a low-risk first sprint.

  • Modern static site with an automated deploy pipeline
  • AWS hosting: CloudFront + S3, HTTPS, your own domain
  • Spam-protected forms and an optional lightweight CMS

Cloud Migration & Transition Planning

Comprehensive workload migration frameworks tailored to small and mid-sized businesses. Every blueprint ships with production-ready Infrastructure as Code to automate core environments.

  • Phased, rehearsed cutovers that protect core operations
  • Zero-downtime transitions timed to low-traffic windows
  • IaC templates you keep and reuse as you grow

Enterprise DevSecOps & IaC

Eliminate configuration drift and manual friction. We design fully automated, modular deployment pipelines, harden security postures, and build repeatable infrastructure patterns.

  • Automated, modular IaC deployment pipelines
  • Security hardening baked into the pipeline
  • Repeatable patterns that scale with business velocity

Apex Monitoring Optimization

Gain total clarity over your active environments. Powered by Apex by CloudHorizon Advisory, we deploy intuitive, high-fidelity monitoring that translates cloud operations into executive-ready visibility.

  • High-fidelity monitoring layers over live environments
  • Straightforward, executive-ready asset visibility
  • Clear lens into cloud topography and spend
How we work

Where engagements start.

Most clients begin with Launch — we build and host their website as a working proof of how we operate — then grow into Migrate and Operate as their needs do. Each stage is built on the one before it.

Start here01 · Launch

Website & cloud hosting

A fast, fixed-scope first sprint. We build and ship your web presence on AWS — the same way we'd run any production workload.

  • Modern static site (Astro) — quick, secure, low cost to run
  • Automated deploy pipeline: every change ships the same way
  • AWS hosting — CloudFront + S3, HTTPS, your domain
  • Spam-protected forms; optional lightweight CMS for staff
  • You keep the repository and the infrastructure as code

02 · Migrate

Workloads & data

The same IaC patterns and pipelines from Launch extend to your core systems — applications, databases, and networking.

  • Well-Architected assessment of the current estate
  • Landing zone defined in Terraform / OpenTofu
  • Database replication with AWS DMS, source kept live
  • Phased, rehearsed cutover with a tested rollback

03 · Operate

Managed ops & visibility

Ongoing operations with Apex in place, so stakeholders keep the clear view of cost and health they had from day one.

  • Monitoring and anomaly alerting via Apex
  • Monthly cost / FinOps review
  • Security patching and updates
  • Executive-ready dashboards and reporting
Continuous, month to month
Architectural blueprint

Two paths, one disciplined method.

Whether you're lifting a legacy estate into a landing zone or building a new serverless front end, the work is planned as code and rehearsed before anything moves. The panels below are illustrative — your architecture is designed to your workloads.

Compliance & hardened isolation

GovCloud & Public Sector Migration

Architecting secure, compliant migration pathways for local government and federal spaces. We build automated, audited landing zones using hardened IaC templates to enforce zero-trust networking and strict access controls.

Zero-downtime workload transitions

SMB Infrastructure Evolution

Helping small-to-medium commercial enterprises break free from on-premises bottlenecks. We design seamless, phased migration blueprints that minimize operational downtime while modernizing infrastructure for elasticity.

High availability & visibility

Database & Pipeline Optimization

Eliminating data latency and delivery blind spots. We specialize in migrating legacy data layers to performance-tuned environments and implementing modular CI/CD pipelines that give stakeholders total operational clarity.

Execution methodology

The CloudHorizon approach.

Once you're past Launch, a migration engagement runs in four disciplined phases — no open-ended exploratory cycles, each ending in a concrete artifact you own.

01

Well-Architected Assessment

A structured deep-dive across your current estate — compute, data, networking, and security — to surface cost leakage, risk, and the shortest safe path to the cloud.

Deliverable: findings & migration roadmap
02

Landing Zone & IaC Blueprint

A production-ready multi-account AWS foundation defined entirely in Terraform / OpenTofu: networking, security baselines, and CI/CD promotion paths.

Deliverable: reusable IaC templates
03

Phased Cutover Execution

Rehearsed pilot migrations and continuous database synchronization via AWS DMS. The final DNS transition runs during a low-traffic window with a tested rollback.

Deliverable: workloads live, source on standby
04

Managed Ops & Apex Visibility

Handoff to ongoing operations with Apex monitoring in place — anomaly alerting, cost review, and a clear stakeholder view of the new environment.

Deliverable: continuous visibility & support
Leadership

Decades of enterprise engineering discipline.
