AWS Cloud Migration Services

Migrate to AWS with zero downtime using the proven three-phase framework: Assess, Mobilize, and Migrate & Modernize.

The Three Phases of AWS Cloud Migration

AWS cloud migration follows three phases: Assess, Mobilize, and Migrate & Modernize. Avahi runs all three as your execution partner, using AWS's own framework and tooling end to end.

Assess

We map your estate, dependencies, and cloud readiness, then build the migration business case with TCO and ROI analysis. Whether the source is on-premises, Azure to AWS migration, GCP, or a PaaS like Heroku, you leave the Assess phase with a workload inventory and a recommended strategy per application.

Mobilize

We stand up a secure AWS landing zone with Control Tower and Well-Architected guardrails, run pilot migrations, close readiness gaps, and build the cloud skills your team needs for day two. The landing zone is delivered as Infrastructure-as-Code you own.

Migrate & Modernize

We rehost, replatform, or refactor workloads at scale, validating each wave on AWS with minimal disruption. Modernization work, from containers to application modernization and OpenAI to Bedrock migration for AI workloads, happens here, so the migration pays for itself in capability and not just hosting costs.

Which AWS Migration Strategy Is Right for You?

The 7 Rs are the seven strategies for migrating workloads to AWS. You don’t need to memorize them; our Assess phase determines the right strategy for each application, backed by AWS cost optimization modeling.
Rehost (lift-and-shift):

Moves workloads fastest; best for stable apps under time or contract pressure.

Relocate:

Moves infrastructure to a new environment without application changes.

Replatform:

Makes targeted upgrades, like swapping a self-managed database for Amazon RDS; the most common choice for Heroku to AWS migration projects.

Refactor:

Rebuilds for cloud-native scale, reserved for apps where the payoff justifies the effort.

Repurchase:

Swaps to SaaS.

Retire:

Decommissions unused workloads.

Retain:

Keeps workloads in place when migration adds no immediate value.

AWS Cloud Migration Case Studies

Sanas: 150M Voice Files Migrated to AWS in 7 Days

Azure GPU costs and 30-second model latencies were blocking Sanas's next product launch. Avahi moved 150 million voice files and the entire GPU-hungry ML pipeline from Azure to AWS in 7 days, 50 percent faster than the original plan, with zero downtime and uninterrupted model training. The cutover ran on AWS DataSync, a Terraform-managed landing zone, and ECS auto-scaling, and the new multi-AZ architecture left Sanas with a ready-to-scale pipeline for faster speech-model release cycles.

NorthBay Healthcare: Telehealth on AWS for a Regulated Provider

Avahi built and delivered NorthBay's telehealth solution on AWS, with the security and compliance posture a healthcare provider requires.

AWS Cloud Migration FAQs

What Is AWS Cloud Migration?

AWS cloud migration is moving your applications, data, and workloads from on-premises or another cloud onto AWS in a planned, low-risk way: prioritizing workloads, testing, and cutting over with minimal downtime.

What Are the Three Phases of AWS Cloud Migration?

Assess, Mobilize, and Migrate & Modernize. You build the business case, prepare a secure landing zone and pilot, then migrate and optimize workloads at scale.

Can you meet strict compliance requirements?

Yes. We implement controls for HIPAA, PCI-DSS, SOC 2, and other frameworks, with audit artifacts generated automatically

How Do You Approach Migration Timing?

We sequence workloads in waves to keep your team productive throughout, rather than committing to a fixed schedule up front. During the Assess phase we scope your environment and map a wave plan, so you know the path before any contract is signed. Larger or refactor-heavy environments are sequenced accordingly.

What Are the 7 Rs of Cloud Migration?

Rehost, Relocate, Replatform, Refactor, Repurchase, Retire, and Retain: the strategies for each workload. Avahi recommends the right R per application during the Assess phase.

Can You Migrate Us From Azure, Google Cloud, or Alibaba Cloud to AWS?

Yes. We run cross-cloud migrations with a unified landing zone and phased cutover that avoids costly rewrites, including Azure, GCP, and Alibaba Cloud sources.

Can You Meet Strict Compliance Requirements?

Yes. We implement controls for HIPAA, PCI-DSS, SOC 2, and other frameworks through our AWS security and compliance practice, with audit artifacts generated automatically.
