Featured Reviews

Mohammad Wasif - PeerSpot reviewer
IT Infrastructure Engineer at Trigyn Technology
Has supported reliable deployments and simplified issue resolution in complex environments
The most suitable feature of CentOS is its exceptional stability, security, and long-term support, which make it a popular choice for enterprise and server environments. CentOS is widely recognized for providing a stable and secure platform, especially suited for server and mission-critical workloads. Whenever we face critical work, it is easy for our team to handle. For long-term support, each CentOS release generally guarantees long-term updates, ensuring reliability for extended periods. For package management, we use YUM and DNF in the new version for flexible and efficient software management. It depends on our users' requirements for installing CentOS. Licensing for CentOS is above my management details, so I am not aware of this information. CentOS always provides good feedback, is easy to handle, and easy to troubleshoot. The experience with CentOS OS has been very good over the last two months. I rate CentOS nine out of ten.

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.
