CentOS and Amazon Linux are leading competitors in the server operating system category, with CentOS offering robustness suited for traditional environments and Amazon Linux providing enhanced performance for cloud-centric operations. Amazon Linux appears to have the upper hand due to its seamless integration with AWS services and optimizations tailored for cloud infrastructure.
Features: CentOS is known for its stability, compatibility with RHEL, and cost-effectiveness due to its open-source model. It is customizable and provides long-term support, making it a reliable choice for enterprises. Amazon Linux is designed for the cloud, offering tight integration with AWS, built-in security features, and optimizations for EC2 instances that enhance network performance and scalability. It also excels in streamlined deployment processes, making it ideal for cloud-based operations.
Room for Improvement: CentOS users often point out the need for better documentation, a more user-friendly experience, and improved long-term support following its transition to CentOS Stream. Concerns about future compatibility with RHEL also arise. Amazon Linux faces challenges with limited third-party ecosystem support and community resources. Users seek more comprehensive tutorials, expanded software compatibility, and enhanced integration with non-AWS environments to increase its adaptability.
Ease of Deployment and Customer Service: CentOS is versatile in deployment environments ranging from on-premises to hybrid clouds, though its community-driven support relies heavily on forums and documentation. In contrast, Amazon Linux benefits from its seamless integration with AWS infrastructure, providing users with an efficient cloud deployment experience. It receives generally positive feedback for its customer service embedded within AWS, though it may lack extensive external community resources.
Pricing and ROI: CentOS is favored by cost-conscious users due to its free, open-source nature, eliminating licensing fees and making it attractive to startups and enterprises focused on budget solutions. It allows for additional savings through its community support model. Amazon Linux offers pricing benefits within the AWS framework, with costs linked primarily to the infrastructure rather than the OS. Both systems deliver substantial ROI, though Amazon Linux stands out for its AWS-optimized efficiencies.
With Amazon Linux, selecting and launching instances on a public cloud provider means the machine spins up in fewer than ten seconds, making it efficient.
By switching the compute fleet from a paid distribution to Amazon Linux, we have reduced our OS-related overhead cost by 100%.
Some wins commonly seen after switching, particularly when moving from general-purpose distributions such as Ubuntu, include approximately twenty to forty percent better price-performance ratio.
I have seen a return on investment, particularly in terms of money saved because I do not pay for the servers.
The money saved was significant, approximately fifteen percent of our IT budget.
It saved a lot of time through troubleshooting, which gives us substantial room for improvement in terms of fixing things.
Amazon has the best expertise and they are available 24/7.
Timely and helpful responses for performance, updates, or AWS integration issues.
Customer support provided excellent assistance, resolving the issue and getting the setup back to working order fast.
I would rate the customer support for CentOS a 10 on a scale of 1 to 10.
I've seen many people across the globe interacting, and when users encounter issues, the community provides solutions.
I would rate the documentation about eight in terms of usefulness.
Since it is tightly integrated with AWS services, I can easily scale instances up or down based on demand using EC2 auto-scaling and load balancing.
Automatic scaling adds or removes servers based on CPU traffic, which is optimal for production applications, while load balancing helps distribute traffic across servers, preventing overloads and delivering stable performance.
The compatibility of container scalability with Amazon ECS and Amazon EKS, along with performance optimizations and low latency for workloads.
CentOS is scalable and user-friendly without requiring complex configurations.
It allows users to scale resources vertically for upgrading hardware and horizontally by adding more servers, making it suitable for modern web hosting and containerized applications.
CentOS's scalability for my organization has handled growth and changing needs smoothly.
Combined with AWS managed infrastructure, it provides enterprise-grade reliability suitable for production workloads.
Since it is purpose-built for the cloud, it lacks the bloat of traditional desktop-focused distributions, which leads to fewer crashes and higher uptime.
Compared to other Linux distributions, Amazon Linux is significantly more stable for AWS workloads because it is pre-optimized for EC2 hypervisor and includes integrated AWS tools out of the box.
CentOS is stable, reliable, flexible, and very useful.
CentOS's simplicity and stability make it easy to use.
I believe CentOS is stable, but we are gradually moving away from it.
Documentation explaining the differences between Ubuntu and Amazon Linux would be valuable.
Since we are working in a real-time manner and need to scale things immediately, the time it takes to boot an instance and then deploy things is preventing me from giving it a perfect rating.
My advice for others looking into using Amazon Linux is to make sure the command line is easy and that Amazon Linux has more performance than other Linux environments and is more secure than other Linux environments as well.
The documentation and support could be improved, along with compatibility with newer hardware as hardware continually evolves over time.
Kernel parameters, sysctl config details, tuned profiles, process prioritization, optimized disk, and input scheduler choice are all points for performance optimization.
CentOS RADIUS server handles sensitive authentication data, so improving security is the priority.
With Amazon Linux itself, there is no cost associated with using it, so I would say it is very good from a pricing perspective.
If I am a new AWS customer, the AWS Free Tier typically includes, for the first six months, micro instances such as t2.micro or t3.micro for free.
I am paying around $300 to $400 per month because I use many services.
There was no cost in terms of deploying it or getting the license for it.
Regarding pricing, setup cost, and licensing for CentOS, there is no cost for licensing or setup pricing.
CentOS is a free product with free updates.
Amazon Linux handles this automatically. It is optimized for EC2, AWS hardware and software, mostly secure and stable, and there is no additional cost.
In terms of service security, there are many constraint security protocols and policies that help me create our own networks, security groups, and inline policies.
Amazon Linux's security updates have been helpful in general because I have had to be more specific in using the Identity Access Management (IAM) service so that we can have role-based permissions in preference to just keeping it open.
CentOS has helped me most through its enterprise-level stability.
The update cycle changed when CentOS was prioritized for updates, causing stability issues.
In my experience, the best feature that CentOS offers is the network configuration of a device from the command-line interface, which is exceptionally clean.
