Containerization has transformed how I run microservices for high-speed web and API workloads

The best features Docker on CentOS offers include its lightweight containers and fast startup. Whenever there was a scale-out required for the APIs, it was immediate, less than 10 seconds to boot up, which was very helpful for the microfinance services. The fast startup and lightweight containers of Docker on CentOS were very helpful because earlier when we used to have these APIs running on the EC2 instances, many instances were required for those services, even though the code was very small. We had to use many EC2 instances instead of using microservices or micro containers like Docker. When we moved to Docker, the scale-out was very fast and very helpful for the business. The boot time with Docker was very less compared to the EC2 instances because running on the EC2 instances required more boot time for the OS, and there was a long delay due to the script execution for a few seconds. Docker on CentOS has positively impacted my organization as it helped us grow the business, and the customer was very happy with the services, thus revolutionizing the business.

Empowers collaboration through streamlined integration and extensive documentation

Improving Red Hat Enterprise Linux (RHEL) can be tough, however, a significant area is collaboration tools. We have many Windows users that use Outlook and Skype or Teams to collaborate on our network. They want Linux desktops due to the fact that they want to use containers. Their biggest complaint is, 'I need two workstations to do my container work and one to collaborate.' If somehow RHEL can start introducing or collaborating with Teams and Outlook so their users can work with their Windows peers, that would be great. But I don't think that's available yet. Regarding pricing, setup costs, and licensing, there needs to be more of an education piece to it. For instance, when purchasing 10 or 100 node licenses, they could suggest, 'We also offer this 1,000 node license instead, and it'll save you specific amounts.' Just more education on their offerings would be helpful, because usually, we're coming out with the requirements, and then they just provide it to us. They could inform us about saving by bundling it differently or using alternative approaches.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Docker on CentOS has improved my organization positively, as it is easy to operate and maintain, making it more flexible—you can change any service in the system, delete or remove the service port, and create new ones."

"We can see faster deployments and reduced environment-related issues since adopting Docker on CentOS."

"Docker on CentOS has positively impacted my organization by improving our time to market."

"Docker on CentOS has positively impacted my organization as it helped us grow the business, and the customer was very happy with the services, thus revolutionizing the business."

"Those features helped me specifically during my project by making it more stable since it used fewer resources, resulting in a cost-efficient deployment, as the machines that I deployed it on used less of the resources than I thought they needed."

"Since Red Hat is known as a popular option for many of our customers, it provides a standardized platform for us to deliver products on."

"Everything is just stable and works well."

"The GUI for network adapters and built-in tools provided by RHEL, such as the Mozilla browser, have been valuable. Since they come built-in, it saves the time of having to install them, and you have everything necessary with the installation itself."

"I rate Red Hat Enterprise Linux (RHEL) a ten out of ten."

"I find the most valuable aspect of Red Hat Enterprise Linux to be its ease of customization."

"Red Hat Enterprise Linux (RHEL) scales fantastically with the growing needs of our company."

"The graphical user interface is useful. However, we prefer to use the command line as we can do many more things."

"I chose Red Hat Enterprise Linux (RHEL) because it is so user-friendly, in every server I need to use it for security reasons, and it is user-friendly for everyone."

More Red Hat Enterprise Linux (RHEL) pros

Cons

"I have not seen a return on investment because the deprecation made it so there was none, and if anything, the ROI would have been negative since money and time were spent using something that did not progress."

"Docker on CentOS can be improved by being in sync with the OS updates."

"Docker on CentOS needs native orchestration and lifecycle management, which are currently limited."

"To achieve a higher rating of 9 or 10, they might need more automation features."

"Its user interface could be better for people who want to use the GUI. They can provide a better user interface with more features."

"Linux overall needs improvement. They cannot go much beyond what Linus Torvalds's kernel implementation can do. I come from AIX, and there were very cool things in AIX that I am missing dearly, e.g., being able to support not only adding, but also reducing memory and number of processors. That is not supported on Linux right now, and it is the same for the mainstream file systems supported by Red Hat. There is no way of reducing a file system or logical volume. Whereas, in AIX, it was a shoo-in. These are the little things where we can say, "Ah, we are missing AIX for that.""

"I would like training to be added to the subscription. It would be useful for when you have to train yourself or get a certification. There are many things that we are not using because we don't know how to use them. Having training included in the subscription would help us in learning more things and utilizing the full power of the solution."

"It isn't hard to patch, but migrating between versions is difficult. We have the the latest version, but the previous version is still working very well. It's hard to leave a working version to upgrade. I would like more AI features, but those will be added to the next version. We are in an AI age, and it's an area where we need to keep pace."

"The primary issues are related to integration."

"Integrating certificates from third-party clients into Red Hat Enterprise Linux can be challenging due to the operating system's stringent security policies."

"Large application vendors may not have certified RHEL, or they have certified an older version. Most of the large application vendors are unfamiliar with the versioning that RHEL introduced, which I strongly support. They will support a given sub-version up to a point, not realizing that the sub-versions are essentially additive."

"It would be great if they're able to reduce the price. It will be easier to convince customers to use Red Hat Enterprise Linux (RHEL) instead of open-source solutions."

Pricing and Cost Advice

Information not available

"Red Hat Enterprise Linux licensing is quite costly, but I personally do not deal with pricing."

"While it isn't inexpensive, it has proven to be a worthwhile investment."

"Red Hat Linux is inexpensive. Linux solutions are generally inexpensive."

"We transferred our license to the cloud because we were originally a VMware on-prem shop. So we're just transitioning some of our workloads to cloud licensing. Also, I have opted for a subscription."

"It's expensive."

"It is very straightforward. We do not have to think much about having to get all the subscriptions related to the Red Hat Enterprise Linux fleet that we have because all the subscriptions came in pairs of CPUs or even for an entire bare-metal server."

"Its pricing and licensing are reasonable."

"Lowering the cost of enterprise-level offerings could attract organizations seeking operating systems or Kubernetes solutions, as these tools are essential for many businesses in the region."
