Devops Engineer at EDAG
Cost-effective platform has enabled extensive test environments with rapid server expansion
The best features CentOS offers in my experience are that it is reliable, cost-effective, and easy to scale. When I mention reliability and cost-effectiveness, I explain that our product-based company uses a performance testing tool, so to generate load using the tool, we use CentOS generators, which are also known as VMs. We spin up a number of VMs in different locations such as Central, East, and West. If we purchase a subscription, it requires a good amount of money, but if we use CentOS, it is free of cost, and we can scale from more than 20 to 100 servers. The biggest benefit of CentOS for my organization is cost saving. CentOS has made a positive difference for my team and company by making scalability easier. For testing, sometimes we require 50 to 200 servers in different locations, and I can easily spin up and scale in and scale down.

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.
