What is our primary use case?
Amazon Linux serves as my primary platform for hosting Nginx web servers and self-hosted Postgres databases. I have also set up HashiCorp Nomad, Consul, Prometheus, and Grafana on Amazon Linux, utilizing a maximum of self-hosted services including all services and APIs as part of DevOps-managed, self-hosted applications.
In a specific project, I used Amazon Linux for these self-hosted services with a tool called Nomad, which is equivalent to Kubernetes. I created a Nomad Consul setup with worker and master-slave nodes specifically on Amazon Linux, where I set up three Nomad servers, three Nomad workers, and Consul as a service mesh. I built an end-to-end use case on Amazon Linux, utilizing Postgres for self-hosting the database connection, which also runs on Amazon Linux.
I have also set up a Key Vault on Amazon Linux, which is a Kubernetes native solution released by the Linux Foundation. It functions as an RBAC authentication layer for application DevOps-level operations. I set up the Key Vault for our application two days ago, and we are using Postgres for it, both running on Amazon Linux, which is performing excellently.
What is most valuable?
Amazon Linux offers many excellent features. Compared to other operating systems, Amazon Linux is quicker and faster than CentOS, Ubuntu, or similar alternatives. Amazon Linux natively supports many AWS features, offers long-term support, and regularly updates security.
Setting up monitoring in AWS through CloudWatch monitoring, log monitoring, or alert monitoring is beneficial due to the clear documentation provided by Amazon. I have set up many things throughout my career using Amazon Linux, and it supports many dependency software and open-source software with free licensing, so there is no need for license purchase or dependencies. It supports all technologies including Nomad, Docker, and Kubernetes, along with many programming languages such as Java and Python with numerous agents available for installation, making it an excellent operating system complemented by strong documentation.
The documentation from Amazon has helped me significantly. When I want to set up something in Key Vault for application-level monitoring, I refer to the clear and well-released documentation from Amazon, which is superior compared to other operating systems. This clarity allows me to set things up quickly and upgrade from staging to production easily.
Amazon Linux has positively impacted my organization through excellent support. The good support provided helps upgrade effortlessly, and security vulnerabilities are professionally fixed quickly while releasing multiple AMIs. I notice this whenever I see an AMI being upgraded within two weeks, which is beneficial for us. Many open-source supported features are available, and the operational efficiency of upgrading to Amazon Linux compared to other operating systems has been significant. We utilize it extensively.
What needs improvement?
Amazon is bringing more upgrades through Amazon Linux 2 and Amazon Linux 2023, and I appreciate that the boot time is fast and upgrades are easy, which represents a positive aspect.
Everything is currently good with Amazon Linux for my needs, and I think Amazon is performing excellently. I have not faced any issues, but if there is any concern regarding the security side, I would appreciate proactive addressing, as we use this in production-level operations. It would be good to have prior knowledge of any potential issues. I am also performing OS hardening while expecting proactive addressing of any third-party vulnerabilities linked to bad software in the repository.
For how long have I used the solution?
I have been working with Amazon Linux from the start of my career, providing six years of experience with Amazon Linux.

How are customer service and support?
Customer support from Amazon is excellent. They provide extensive support for any obstacles we face and for everything we want to accomplish. When I raise a case with AWS, they assist effectively.
Which solution did I use previously and why did I switch?
We have been using Amazon Linux from the start.
Before choosing Amazon Linux, we evaluated other options such as Ubuntu because they also provide support and have a competitive market presence compared to other Linux distributions.
How was the initial setup?
We have not purchased Amazon Linux through the AWS Marketplace since it is offered in the AWS Launchpad itself, and we are using that OS.
What was our ROI?
In terms of money saved, many operating systems impose charges. We save considerable amounts since we do not have to pay for an OS such as Kali Linux. The free license and support mean we save considerable time launching. 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.
What's my experience with pricing, setup cost, and licensing?
My experience with pricing, setup cost, and licensing is quite positive. The pricing is free compared to many other operating systems that charge. I appreciate that there is no license renewal required, and it is a free tier for us, which makes it very convenient. Amazon's straightforward approach on these matters means no additional costs involved, making everything quite comfortable for us.
Which other solutions did I evaluate?
We use AWS, or Amazon Web Services, as our cloud provider.
What other advice do I have?
Regarding specific outcomes or metrics with Amazon Linux, I can first say that production upgrades enhance security. Amazon Linux runs faster compared to other operating systems such as CentOS, Kali Linux, and Ubuntu, making the startup and boot-up script run fast during launch time.
I rate Amazon Linux a nine out of ten. I choose this rating because I am concerned about the repository possibly containing vulnerability packages, though this could happen with any system.
My advice for others looking into using Amazon Linux is to explore the many features available. Several aspects such as Session Manager for public cloud connection and startup scripts are useful. Security-wise, it is also robust, and various software packages are available in the registry. If something is not found, it is easy to install open-source software. Monitoring applications at a custom CloudWatch level is also supported, so I recommend exploring Amazon Linux first since it is free. Overall, I would rate this product a nine out of ten.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
