What is Modernization on AWS?

AWS has significantly evolved over the years, continuously releasing new services and capabilities that allow its customers to do more and more on the cloud. For customers to take advantage of this, meet the demands of modern technology, and maintain a competitive edge in the market, the need to modernize IT infrastructure and applications is paramount.

Modernizing on AWS refers to migrating and transforming traditional applications, workloads, and infrastructure to leverage the benefits of cloud computing and AWS services. This involves updating existing systems to take advantage of modern cloud-native architectures, technologies, and best practices, which always follow the six Pillars of AWS Well Architecture Framework: Operational Excellence, Security, Reliability, Performance Efficiency, Cost Optimization, and Sustainability.

Companies are modernizing the cloud through various strategies and approaches.

Xebia has vast experience supporting customers in assessing their existing infrastructure and aligning on the best approach for their modernization journey. This, of course, takes into consideration the organization’s strategy, business and technical goals, security, and compliance requirements.


Many companies start their cloud modernization journey by migrating existing applications and workloads to the cloud. This could involve lifting and shifting applications as-is to cloud infrastructure or refactoring them to take advantage of cloud-native features and services.


Refactoring involves redesigning and optimizing applications to utilize cloud-native features and services better. This may include breaking monolithic applications into microservices, containerizing applications using Docker and Kubernetes, or adopting serverless computing with AWS Lambda.


Modernization typically involves automating processes for deployment, scaling, monitoring, and management using AWS services like CloudFormation, Elastic Beanstalk, OpsWorks, and CodePipeline. Automation improves efficiency, reliability, and agility in the cloud.

Adoption of Cloud-Native Technologies:

Companies embrace cloud-native technologies such as containers, serverless computing, and microservices architecture. Containers enable consistent deployment and management of applications across different environments, while serverless computing allows developers to focus on writing code without worrying about infrastructure management.


Containerization simplifies container orchestration and management and enables consistent deployment and management of applications across different environments. Organizations utilize managed services such as Container Service (ECS) and Elastic Kubernetes Service (EKS) for running containers, along with services like Fargate for serverless container management.

Serverless Computing:

Serverless computing allows developers to focus on writing code without worrying about infrastructure management. AWS Lambda enables running code in response to events without provisioning or managing servers, while the API Gateway provides a scalable and fully managed API gateway for serverless applications.


Modernizing with microservices involves breaking down large, monolithic applications into smaller, independent services that can be developed, deployed, and scaled individually.

Data Modernization:

Modernizing data infrastructure involves migrating and optimizing databases, data warehouses, data lakes, and analytics solutions. Companies are leveraging cloud-based data services such as managed databases, data lakes, and analytics platforms to gain insights from their data more effectively.

DevOps and Automation:

DevOps practices and automation play a crucial role in modernizing applications in the cloud. Companies are adopting CI/CD pipelines, infrastructure as code (IaC), and automated testing to streamline cloud applications’ development, deployment, and operation.

Hybrid and Multi-Cloud Strategies:

Hybrid and multi-cloud strategies to modernize the IT infrastructure involve running workloads across on-premises data centers and multiple cloud providers to leverage the unique capabilities of each environment while maintaining flexibility and avoiding vendor lock-in.
