What is our primary use case?
The solution is used for on-premises data centers. Multiple private data centers run workloads on VMware Cloud solutions, and Red Hat Enterprise Linux is deployed on critical systems. We use KVM virtualization technology to host various virtual machines on Red Hat Enterprise Linux that run workloads and applications.
How has it helped my organization?
Red Hat Enterprise Linux improved our compliance by working with third-party security providers, like CIS Enterprise Internet Security. It's a nonprofit organization that provides many security solutions and benchmarking for each operating system. CIS and Red Hat jointly developed a CIS-approved operating system. They work with various public cloud providers like App Engine, Google, and AWS to provide comprehensive CIS-approved images in Red Hat Enterprise Linux.
The US federal government has already certified the OS for FIPS compliance. FIPS is the organization that designs cryptography algorithms for federal agencies, and they approved Red Hat Enterprise Linux.
It takes some time to realize the benefits. Some customers cannot see a direct benefit because the licensing is a bit complex. In a huge enterprise environment, you could see an immediate effect, but a smaller or medium-sized organization may take a while to yield a return on investment.
What is most valuable?
The most significant advantage is that it is more stable and secure than other operating systems. Years ago, we worked on Windows-based systems with more challenges regarding patch management and vulnerabilities than Unix operating systems. We get more frequent patch releases from the vendor weekly, monthly, and quarterly. It also has strong security features, is OIS and FIPS certified, and has built-in Linux security configurations.
In addition to Linux's built-in security tools, it has Red Hat Enterprise Linux configuration features that provide robust security controls. We also have third-party solutions that provide more in-depth solutions for our cloud and on-premises infrastructure. We have to provide security at each layer of the OSI models. For example, on the application layer, we have to provide web solutions or application gateways, but it provides good security features for the OS layer.
We use another Red Hat product called Ansible to automate patching tasks and infrastructure deployment. We don't have a large number of servers, so we manage patching and configuration through Ansible. For bigger deployments, they have solutions like Satellite, but we use Ansible.
We use Image Builder to create a Golden Image for our CICD pipelines. We have a CIS-approved image that integrates their security controls for our automation tools and some of the ones specific to our organization. We added some of the controls from the Red Hat management framework that govern how an image should be created and what controls must be integrated into this base image.
The web console is useful for people without Linux backgrounds who lack experience working with the command prompt. The web console helps them manage the system better without knowing all the commands.
What needs improvement?
Red Hat Enterprise Linux licensing is a bit complex. The solution operates on a subscription-based model, which may not provide immediate return on investment for small to medium-sized organizations. It also has a steep learning curve for employees unfamiliar with Linux, and it demands a skilled team or a dedicated service center to operate effectively.
For how long have I used the solution?
I have used Red Hat Enterprise Linux for about four to six years.
What do I think about the stability of the solution?
Red Hat Enterprise Linux offers great stability and performance compared to other operating systems. It does not have issues with crashing or substantial downtime.
How are customer service and support?
I rate Red Hat support seven out of 10. We have only opened one or two cases with technical support, but we've had good experiences. They respond immediately based on the SLA level. In the future, we plan to use Red Hat's OpenShift and Kubernetes solutions, so we expect to work with the support team more because we're new to those products.
Red Hat's Knowledgebase is an excellent support resource. It stays updated about new things coming to our region and provides lots of articles about the products. It's a good starting point for troubleshooting without the need to call the support team. We use the knowledgebase to resolve issues as often as we can, but we contact support if we get stuck and can't find the solution.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
We have physical systems running SUSE Linux and Windows, but we're gradually migrating them to Red Hat Enterprise Linux. Some systems are running Solaris, and we haven't decided whether we'll migrate to Red Hat Enterprise Linux or other operating systems.
How was the initial setup?
Our operations team takes care of migrations and installations. We're primarily responsible for business impact assessments and helping the operations team do a POC to determine the effect on the application environment. We consider the licensing and give the operations team approval to do the migrations and install the new operating system.
The team consists of two or three people. We cannot migrate directly from one system to another. We simulate everything in the POC environment and perform migrations in the development environment using our in-house tools. They will check the source machines and find out what applications are running. It will assess them and look into the destination systems. Using some replication technology, it will do a direct synchronous verification between one storage to the other.
We need some downtime to complete the migration, and most of the data is stored in SAN storage. That is called a long migration. Once the operating systems and associated patches and applications have been migrated, we have to migrate them manually for the storage side.
What about the implementation team?
What's my experience with pricing, setup cost, and licensing?
The subscription-based pricing can be costly, particularly for smaller deployments. The more subscriptions you have, the easier it is to see a return on investment because it helps larger organizations more. It may be considered expensive compared to other solutions like CentOS or Ubuntu, which offer some of the same features without additional costs.
What other advice do I have?
I rate Red Hat Enterprise Linux eight out of 10. I recommend new users get some training on the platform because installations and migrations can be complex. Setting up clusters can be challenging for new users who don't have hands-on Linux experience without vendor assistance.
Which deployment model are you using for this solution?
On-premises
