Modern Cloud Migrations That Go Beyond Lift-and-Shift

ATG helps organizations move to AWS with purpose — modernizing architectures, improving performance, and reducing costs along the way. From legacy workloads to cloud-native redesigns, we use proven AWS frameworks and automation to deliver migrations that are fast, secure, and built for scale.

Modernizing the Right Way on AWS

Cloud Migrations Built for Performance, Security, and Scale

Every migration is different — but success always starts with the right strategy. ATG’s Cloud Migration approach combines deep AWS expertise, automation, and modern architectures to ensure your workloads perform better, cost less, and scale seamlessly. Whether rehosting, replatforming, or refactoring into serverless or container-based architectures, we help you choose the right path forward — balancing speed, security, and business impact every step of the way.

Migration Strategy & Workload Assessment

We start by evaluating your existing applications, dependencies, and infrastructure to determine the best migration approach — rehost, replatform, or refactor. This ensures every workload lands in AWS optimized for performance, compliance, and cost efficiency.

Cloud Native Modernization

Legacy doesn’t have to mean limitation. We modernize workloads using AWS-native services like Lambda (serverless), Fargate (containers), RDS (managed databases), and EKS (Kubernetes) to improve scalability, reliability, and long-term maintainability.

Secure & Compliant Foundations

Security isn’t an afterthought — it’s built into every migration. We implement identity controls, encryption, logging, and compliance guardrails aligned with frameworks like SOC 2, HIPAA, and CMMC to ensure governance from day one.

Automation & Continuous Optimization

Using infrastructure-as-code, CI/CD pipelines, and AWS CloudFormation, we automate deployment and configuration to ensure consistency and repeatability. Post-migration, we continuously optimize performance and cost with AWS-native monitoring and analytics tools.

How It Works

ATG’s Migration Framework

ATG delivers migrations that go beyond lift-and-shift — transforming legacy workloads into modern, cloud-native solutions that perform better, scale smarter, and cost less on AWS.

Discovery & Assessment

We use AWS-native and partner tools to inventory workloads, analyze dependencies, and model the total cost of ownership. This discovery phase sets the strategy for migration scope, sequencing, and architecture design.

Architecture & Modernization Design

Our AWS-certified architects design scalable, secure, and efficient cloud environments tailored to your workloads. We balance modernization with pragmatism — introducing cloud-native services where they deliver clear, measurable value.

Migration Execution

We migrate workloads with precision using automation, data replication, and phased cutovers to minimize downtime. Our team follows AWS MAP methodology to ensure every migration is fast, secure, and fully validated.

Optimization & Continuous Improvement

After migration, we fine-tune resource configurations, enable monitoring and cost optimization, and establish a roadmap for ongoing modernization. The goal: continuous performance gains and smarter cloud operations over time.

Testimonials

Don’t Just Take Our Word for It

“Prior to working with ATG, we weren’t aware of all we could do with AWS nor did we have the time, skills or people available to find out. ATG helped improve our security posture for our internal applications as well as customer deployments, and showed us a number of different options for using native AWS tools to help our services and product teams scale faster and more cost-effectively.”
