Private cloud practice has become seamless and deployments run smoothly for my projects
What is our primary use case?
My main use case for AlmaLinux is based on my recent hands-on experience with AlmaLinux 9 for OpenStack deployment, and I am happy to share my feedback on PeerSpot.
To give a quick example of how I am using AlmaLinux for my OpenStack deployment, here is a brief review based on my recent production deployment experience. It involves deploying a full OpenStack Yoga environment for a private cloud setup, which is my personal project for practicing. The initial attempts on Red Hat distribution faced compatibility and subscription repository configuration hurdles, but I found solutions to switch to AlmaLinux 9.6, which offered perfect compatibility with Packstack without the licensing overhead.
There are key wins from my side: AlmaLinux 9 has zero subscription friction, direct access to the latest patches, and smooth installation of OpenStack Keystone, Nova, Neutron, and Horizon via Packstack. Moreover, stable OVS networking and floating IP configuration is very easy for me when using AlmaLinux, making it a reliable and highly recommended option for teams needing an enterprise-grade Red Hat compatible workflow without the subscription cost.
After struggling with various Linux distributions for almost seven days, mainly dealing with missing tools while installing network components like Neutron in OpenStack, I turned to AlmaLinux. It was then that I discovered that full OpenStack installation with AlmaLinux is highly compatible. Eventually, I successfully configured the full OpenStack platform, which is something my interviewer board also accepted.
My deployment of AlmaLinux starts locally to connect servers, requiring multiple nodes. Initially, I test in a local environment before transitioning toward a public cloud setup, which is a practice session for me. I also suggest to our public cloud team that they utilize AlmaLinux, as I find it quite comfortable.
Regarding AlmaLinux's scalability, I find that it scales well in both vertical and horizontal dimensions due to its one-to-one compatibility with Red Hat and an enterprise-grade kernel. For vertical scaling, adding more CPU, RAM, or storage is seamless, and tools like tune allow for quick performance profiling. Horizontally, while using AWS, I successfully scaled applications significantly during traffic spikes without OS-related issues, and I managed to add new compute nodes effortlessly within the OpenStack cluster.
What is most valuable?
The best features AlmaLinux offers include zero-subscription friction and direct access to the latest patches, which I think are essential. Additionally, it also provides up-to-date packages and stable versions that are very useful for me.
When I say direct access to the latest patches, it has greatly benefited my projects by being absolutely hassle-free. In contrast to Red Hat, where I had to configure the Yum server for updates or deal with subscriptions, AlmaLinux allows a far simpler process without the complexities involved.
At this moment, AlmaLinux is a very open platform. It not only includes the latest security patches but also integrates very recent AI technologies alongside the direct patches that help harden the server.
I have noticed several positive impacts of using AlmaLinux on my organization and personal projects. Trying multiple distributions like CentOS, Red Hat, and Ubuntu for my personal OpenStack installation revealed how complex it can be to set up. I find AlmaLinux to be reliable, providing the latest patches on a secure platform. Many people suggest AlmaLinux 9 on public platforms for its excellent features, and I benefited from the step-by-step configuration provided, leading to the acceptance of my project.
What needs improvement?
I follow the documentation for AlmaLinux, which I believe could be more extensive for enterprise setups. My primary use case remains deploying private cloud infrastructure using OpenStack Yoga, thus suggesting improvements to cater to specific cloud instances like AWS Graviton or Azure NVMe.
Driver or kernel updates for new hardware or cloud instances like AWS Graviton or Azure NVMe tend to arrive a little later in AlmaLinux than they do in the Red Hat distribution. Therefore, I suggest that faster releases of cloud-optimized images and updated hardware drivers could enhance AlmaLinux's competitiveness. Additionally, I find it sometimes difficult to find answers on forums due to the community not being as large as that of Red Hat or CentOS. My suggestion is to create an active forum or Q&A session where developers can directly address user problems, growing the community and providing optional enterprise support tiers for large organizations.
Additionally, I have continued to consider improvements. For server administration and language runtime management, I encountered conflicts on production servers with older and newer versions of tools such as Python and Node.js. Simplifying the application space management would reduce the friction in multi-language development environments. Moreover, including more pre-configured or auto-remediation scripts like CIS Benchmark or STIG compliance would be immensely helpful for enterprise security hardening.
For how long have I used the solution?
My experience with AlmaLinux spans almost two years.
What do I think about the stability of the solution?
While I do not yet use AlmaLinux in a production capacity, my use case for my blogging activity has demonstrated its stability. Official blogs also verify that the stable version of AlmaLinux is acceptable for production purposes.
How are customer service and support?
I have not utilized customer support for AlmaLinux as of yet, mainly relying on public resources and the official documentation.
Which solution did I use previously and why did I switch?
Prior to using AlmaLinux, we utilized Red Hat, which posed significant financial challenges due to its subscription model and complexity. Comparatively, AlmaLinux serves as a very suitable alternative, matching the Red Hat environment with lower costs.
How was the initial setup?
I follow the documentation for AlmaLinux, which I believe could be more extensive for enterprise setups. My primary use case remains deploying private cloud infrastructure using OpenStack Yoga, thus suggesting improvements to cater to specific cloud instances like AWS Graviton or Azure NVMe.
What was our ROI?
In terms of return on investment from using AlmaLinux, I maintain that since we use the free version, we have saved significantly and have encountered fewer security risks. If the AlmaLinux team announces that the latest version complies with CIS benchmarks and security protocols, I will continue to endorse AlmaLinux.
What's my experience with pricing, setup cost, and licensing?
Currently, we have not experienced pricing with AlmaLinux, as I have used the free version so far. However, when we move to the production environment, I am suggesting that we implement AlmaLinux to improve our performance metrics.
Which other solutions did I evaluate?
Before settling on AlmaLinux, I evaluated other options while testing in a local environment, especially for students encountering financial constraints. Given its resemblance to Red Hat and CentOS, I recommended AlmaLinux as the best solution due to its free nature.
What other advice do I have?
On a scale of one to ten, I would rate AlmaLinux at 8.5 overall.
The reason I chose 8.5 out of 10 stems from my perspective as a user focused on OpenStack deployments. Despite being subscription-free and reliable, I find some complexities in the documentation and troubleshooting guides which are not as comprehensive as Red Hat's. There is also a lack of 24x7 support, leading to a reliance on community assistance, and while the migration tools are useful, they do raise warnings with legacy systems. Additionally, hardware support is occasionally slow for newer driver versions, which is why I score it as I do.
My advice for others considering AlmaLinux is that it is a fantastic product and a reliable alternative to Red Hat, matching its kernel. I recommend that students use AlmaLinux for local deployments and testing packages, as it is secure and dependable. I gave AlmaLinux an overall rating of 8.5 out of 10.
Which deployment model are you using for this solution?
Private Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)
Hosting critical sites has become efficient and secure while daily administration remains simple
What is our primary use case?
I have been using AlmaLinux for the last 2.5 years. In my organization, we use a Red Hat Enterprise version, but I required Red Hat alternatives to work in my home setup, which is why I chose AlmaLinux. I have hosted one site locally as well as in AWS, and during that time I have hosted that site on AlmaLinux. I deployed one EC2 instance using AlmaLinux OS, and on that OS, I set up that website.
What is most valuable?
AlmaLinux provides the DNF command to install packages, making it very easy to install any package. The patching and security patches are very reliable in my environment.
Before AlmaLinux, I used a CentOS system. In CentOS, if you want to install any packages, you have to install that package using the RPM command, which only installs a specific package. With AlmaLinux using DNF, it installs the whole packages with their dependencies, which is a bit easier.
Stability is good in AWS as well as when I installed it on VirtualBox, so stability and performance are very good. It uses minimum resources while providing high performance.
AlmaLinux does not require any specific additions from my side; it only requires strong support as Red Hat provides. This means the organization can make and afford to use it.
What needs improvement?
To improve AlmaLinux, some commands could be automated, such as expanding the repository of AlmaLinux or improving the shell experience.
There is not vast information about AlmaLinux on Google or the internet, so more information is required about how it works, how it can be used for hosting sites, and how to optimize performance. This documentation is needed on the internet.
For how long have I used the solution?
I have been working for the last 2.5 years as a system engineer.
What do I think about the stability of the solution?
What do I think about the scalability of the solution?
The scalability of AlmaLinux is good.
How are customer service and support?
I had a good experience with the customer support team of AlmaLinux.
Which solution did I use previously and why did I switch?
I was using CentOS, but after CentOS support was lost, I switched to AlmaLinux.
What was our ROI?
I do not have specific metrics to share regarding return on investment, but it is a cost-effective OS.
What's my experience with pricing, setup cost, and licensing?
My experience with pricing, setup cost, and licensing is good.
Which other solutions did I evaluate?
I did not evaluate other options before choosing AlmaLinux.
What other advice do I have?
Computing power could be added while executing the commands to illustrate positive outcomes, but there are no specific metrics available at this time. Two points were deducted only for the support aspect. Any Linux distribution can be shifted to AlmaLinux, as it is very good to use and easy to manage. I would rate this product an 8 out of 10.

Dual environments have strengthened my security testing and scripting for cloud projects
What is our primary use case?
My usual use cases for AlmaLinux include when I need to spin up a server. For example, when I am working on an AWS project, a cloud project, and I need to connect my EC2 instance, a virtual machine, on my cloud in real time to a Linux environment. I quickly go to AlmaLinux to spin up that server and then I begin to carry out my task on the environment.
What I found about AlmaLinux to be very useful in my day-to-day activities is the control and isolation that it provides for applications. When you're working on AlmaLinux, it gives you isolated security that does not affect my host computer. The security that I enjoy in AlmaLinux allows me to perform any security tasks that I need. For example, if I need to access vulnerable websites or applications, it gives me this controlled environment, similar to a sandbox, providing me with a controlled room to do what I need to do without affecting my host operating system.
AlmaLinux helps me enforce security policies in my organization. When we need to partition our networking segment security on different layers, AlmaLinux comes to the rescue. When I have Linux tasks to perform, I go to AlmaLinux, which provides that standalone Linux operating system for me. This does not affect my Windows operating system in any way. It enables me to carry out all tasks that I need to do, all shell tasks, conduct my Bash scripting, my Python scripting, and helps me carry out those automation and scripting languages that I need.
AlmaLinux helps me to have dual operating systems on my host computer. I am able to run my Windows operating system seamlessly and at the same time run my Linux environment seamlessly.
Everything boils down to the isolation, networking, and segmentation that AlmaLinux provides. In terms of security, configuration, and Linux tasks that you need to run, as a system administrator, you would most likely work with Linux more than half of the time. Running on AlmaLinux infrastructure helps you own your Linux skills, and that is how I would describe it. It gives you ownership.
Using AlmaLinux was a condition to do my job, and right afterwards, I have been enjoying it. I have stuck with it and never had a reason to go back. I enjoyed working with it, and even this morning, I had some tasks that I had to spin up on AlmaLinux.

What needs improvement?
For governance, AlmaLinux by default enables one to comply. If you're building an application and AlmaLinux is your host operating system, it helps you comply with industry standards because it will force you to set up your firewall, create your routing rules, and all of that. These are what ensure governance.
In terms of resource allocation, AlmaLinux requires you to have at least ten gigabytes of RAM storage and four gigabytes of CPU allocation. For my system, I consider it a mid-level system and not a very high-performing laptop. I would say it can impact IT professionals like myself who have low or medium-scale laptops, suggesting a reduction in resource allocation for CPU and RAM.
For how long have I used the solution?
I have been working with AlmaLinux since last year.
What do I think about the stability of the solution?
AlmaLinux is 100% stable and reliable for every task that I have had to carry out on it.
What do I think about the scalability of the solution?
Regarding how scalable AlmaLinux is, I would rate it over 80%.
How are customer service and support?
I have not had a reason to communicate with the technical support of AlmaLinux because everything has been smooth for me.
Which solution did I use previously and why did I switch?
I initially started with Ubuntu and then migrated to Kali Linux. From Kali Linux, I went into AlmaLinux because of a project I was currently working on for a client who specifically indicated that I use AlmaLinux for that project. That was how I transitioned from Kali Linux to AlmaLinux.
How was the initial setup?
I set up AlmaLinux on my machine myself. I went to the official AlmaLinux website, found the ISO image file that I needed, and verified the checksum file on my PowerShell before I installed it to ensure that I installed the verified and authenticated ISO image type.
I found the initial setup process to be straightforward. I documented the entire setup on LinkedIn and could share the link if needed.
What about the implementation team?
I utilized the whitepaper on AlmaLinux from their official website to set up and configure AlmaLinux last year.
What was our ROI?
AlmaLinux impacts an organization by helping you understand when there are errors or flaws that you need to mitigate by providing you the logs. The errors and logs are found when you initiate it, helping in communication because you are able to read your log files and communicate with your colleagues about what I have seen on the logs, stating we have to fix specific issues.
What's my experience with pricing, setup cost, and licensing?
I am not aware of the pricing and licensing of AlmaLinux because I installed it on my hypervisor for free.
What other advice do I have?
AlmaLinux's compatibility with RHEL packages does enhance my mitigation needs. I run AlmaLinux on a VMware Workstation Pro, which provides a fast experience for me. There are no roadblocks because I have already versioned my firewalls and created a configured firewall that helps me patch security.
Significantly, AlmaLinux has a huge impact on my package management strategy with DNF because of the isolation that it provides for me.
For enhancing the documentation, I do not see any reason to do so because every bit of information that I needed was contained in it. I followed it, and the entire process for the setup was not difficult at all for me, personally. I would rate this product an 8 overall.
Which deployment model are you using for this solution?

Hosting workloads have gained stronger security and virtualization while performance stays consistent
What is our primary use case?
I provide hosting and email services for customers using AlmaLinux. Most of our customers are using Plesk for managing their domains, and some servers end up having 300 or 400 domains, while others have around 50. Overall, the setup is the same; all of them are using AlmaLinux 9 or AlmaLinux 8, and we are currently configuring and migrating all of our infrastructure towards the newer AlmaLinux technologies and operating systems.
What is most valuable?
In my experience, the best features that AlmaLinux offers are not really different when comparing it with CentOS because we actually migrated from CentOS to AlmaLinux. AlmaLinux seems a bit more stable, but if we're talking about speed and efficiency, I noticed some gaps. For example, some of the services or web services that we are using acted differently on CentOS compared to AlmaLinux 9 or AlmaLinux 8 in terms of response times and memory consumption. We had many issues with memory consumption, and when we actually migrated initially, we migrated from servers that were using around 8 gigabytes of RAM, but when migrated to AlmaLinux 8, they needed more memory instead. So the customer needed to actually buy more memory. Even though AlmaLinux provided more stability and security patches, this came with a cost in terms of memory usage, and that was not really expected.
Positively, I can say that AlmaLinux has brought a sense of stability, and besides the security patches, we also noticed better virtualization for our use cases. Stability, security patches, and improved virtualization are the main positive aspects I have observed.
What needs improvement?
I would like to see better tools in terms of memory consumption with AlmaLinux. I would like to know what processes exactly are consuming how much memory and have better core dumps or system core dumps so I can access them and investigate them instead of feeding the server with more and more memory. Another thing I would like to see is still about memory consumption; I would like to see an optimized kernel for AlmaLinux. The AlmaLinux team can look into this and see what they can improve in terms of resource consumption and monitoring tools that can actually help the users of AlmaLinux pinpoint the exact processes or services that are causing that amount of resource consumption.
Memory consumption when we migrated from CentOS to AlmaLinux was a really big hit for us, and we didn't expect it. After six months of migration, we ended up using more resources for the same websites, and that's not acceptable.
For how long have I used the solution?
I have been working in my current field for about five years.
What do I think about the stability of the solution?
How are customer service and support?
AlmaLinux customer support is really nice; they provided us with quite some solutions for the problems we encountered.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
We used CentOS before AlmaLinux.
What about the implementation team?
We are the provider; we provide AlmaLinux servers and infrastructure to our customers.
What other advice do I have?
My advice for others looking into using AlmaLinux is to just try it out and see if it suits your needs, and if it does, that's great. I would rate this review an 8 out of 10.
