Containerization has streamlined microservices delivery and ensures consistent hybrid deployments
The capabilities of Docker on CentOS that I have found the most valuable include its use for Spring-based applications, which significantly enhance the value I derive from it. Docker on CentOS is particularly effective for building distributed applications and microservices. Deployments are smooth and easy, and the integration with Kubernetes is seamless. I have successfully managed 80-plus pods clusters, scaling from 80 to 85 with 140 TPS without encountering any issues. Docker on CentOS's lightweight nature allows for flawless development across environments such as dev, stage, and prod. From my perspective, the experience with the deployment of Docker on CentOS is quite positive, especially for the CI/CD pipeline. The architecture overview includes the use of a Git repository and GitLab CI, which facilitates the Docker build for our Spring 3.x Java applications.

Auto-scaling microservices reduce costs while ensuring fast, reliable document parsing
While ECS-Optimized Amazon Linux has provided significant benefits in terms of scalability and cost optimization, we have encountered a few operational challenges. One limitation is application-level debugging. Compared to traditional EC2 instances, troubleshooting in ECS can be more complex because containers are ephemeral. Without centralized observability tools, it is more difficult to pinpoint the exact source of an issue, such as the specific line of code, request, or service responsible for an error or performance bottleneck. To address this, we have implemented our own centralized logging and monitoring solution to improve visibility into application behavior. Another consideration is resource sizing. Our microservices have relatively modest memory requirements, so the available ECS task configurations are sufficient for our workloads. However, for large, monolithic applications with higher memory and compute requirements, scaling can require a different architecture or deployment strategy. Since our platform is built using independently scalable microservices, this has not been a significant limitation for our environment.
