Client's Needs
Camil had been experiencing issues with its servers and databases due to a lack of available physical resources in the on-premise data center, along with the technical depreciation of the physical assets supporting the production environment. As a result, the company's IT team was looking for options to migrate to a cloud environment that could meet their scalability and availability needs.
Since the development environment and new projects were already running on AWS, Camil decided to migrate all its production workloads to Amazon Web Services (AWS). They chose AWS because it provides a reliable and scalable cloud infrastructure with a wide range of available resources. Additionally, AWS is highly secure, with a good track record of protecting against cyber attacks.
Solution Architecture
As Camil already had workloads running in separate accounts by environment, and the organizational structure was already in place, we reviewed and improved the landing zones, configuring AWS Control Tower for the application of global policies.
All servers were created using Terraform (Infrastructure as Code), automated through pipelines, and data was migrated to the application servers.
Database servers were migrated using the AWS Database Migration Service, following the planned migration waves after the testing and validation phase of smaller workloads.
The migration process was controlled and managed using AWS Migration Hub, facilitating the visualization of migrated assets and those yet to be migrated, tracking the project phases.
Results
With the migration to AWS, Camil achieved impressive results, including better server management through AWS System Manager for inventory and patch application, system performance optimization with higher quality servers, increased processing capacity and on-demand resources, as well as greater agility in launching new applications and services, accelerating time to market and driving innovation. Furthermore, the company achieved improved governance in the production environment change flow and remarkable speed in creating isolated environments for development.
