Overview 

In today's digital-first environment, organizations rely on cloud adoption and modernization to stay competitive. Our OnX Sr. Cloud Architects partner with clients to migrate and modernize workloads on AWS, design secure and scalable architectures, and provide hands-on expertise throughout project delivery. We leverage AWS-native services, automation, and Infrastructure as Code (IaC) to build resilient systems that enable data-driven insights, operational efficiency, and innovation. 

We help clients accelerate their cloud journey by delivering architectural best practices, migration frameworks, and actionable roadmaps that align business strategy with technology outcomes. More than just technologists, we accelerate our customer’s journeys.

Our team works with clients to: 

• Migrate and modernize workloads from on-premises and other clouds to AWS. 

• Design and implement scalable, secure, and cost-optimized AWS solutions. 

• Build and maintain Infrastructure as Code frameworks for repeatable and automated deployments using CloudFormation, CDK, or Terraform

• Provide architectural documentation and solution diagrams for clear communication and planning.
• Align our work to the AWS Well-Architected framework, providing assurance of governance and continual improvement.

• Design and implement containerized solutions with Amazon EKS and Kubernetes. 

• Create CI/CD pipelines for IaC and application deployments, ensuring proper change management.
• Implement observability solutions including services such as Amazon CloudWatch, AWS X-Ray, Datadog, New Relic, OpenSearch, and others.

• Deliver consulting and advisory services to guide clients through complex cloud transformation initiatives, including the seven Rs of migration.

• Implement and optimize Kubernetes and EKS solutions: Design, deploy, and manage enterprise-grade container orchestration environments. 

• Develop IaC frameworks: Build automated deployment pipelines using CloudFormation, AWS CDK (TypeScript), and Terraform. 

• Enable CI/CD for IaC and workloads: Implement continuous integration and delivery pipelines for cloud infrastructure and applications. 

• Engage with clients directly: Provide consulting expertise, conduct workshops, and lead solution design discussions with business and technical stakeholders. 
• Operate with autonomy: Our architects are empowered to be highly autonomous and responsible for their deliverables, while OnX is designed to do everything it can to help you see projects to a successful conclusion.

• Stay current on AWS services and trends: Recommend and integrate new AWS services to continuously improve client environments.
