Red Hat Enterprise Linux (RHEL) Primary Use Case

Don Beyer - PeerSpot reviewer
Systems Administrator at Ithaca College

Our primary use case for RHEL is running our front-end web servers. When you visit our site, all of the front-end servers are Red Hat. The databases that are hosted are Oracle and they predominantly sit on Red Hat 7. We're trying to migrate those to version 8.

We also use it for BI.

We have a digital footprint in Azure and AWS, as well as on-premises. Things for us are very fluid. We're always changing and adapting to our environment, based on what the needs of our faculty and students are.

Our primary use case is to develop the servers and production. It's pretty standard usage. We have some Docker running but I haven't been involved in those environments very often. It's a standard server on minimal load and we're not using a full load with our GUI interface.

We have multiple applications running on both Windows and RHEL. The database systems are mostly MySQL. There's some Oracle but most of it is MySQL. Dealing with Red Hat is pretty straightforward. I haven't run into issues with it. 

When we were running multiple versions of Java, if patches came out for both versions, we would apply the patches for both versions and usually, that could be downloaded. It was pretty simple to update those. Those are systems-supported patches. With the specific application patches, it's a little different. Normally the application administrators take care of those themselves.

If Red Hat's system is set up right, it improves the speed and performance reliability of our hardware because it doesn't use as many resources as a Windows system.

We use a combination of Red Hat and Oracle Linux in different parts of the organization. We have a cluster, where RHEL is running. The instances are both virtualized and real, depending on which part of the cluster you're utilizing. They are set up as either RAC or single instance, depending on what we are trying to achieve in terms of performance.

We have PeopleSoft systems that are all deployed on Red Hat. We also use it for deploying simple websites. PostgreSQL is running on the systems, along with a frontend that was created by the developers. We also use it for DNS fallback authentication.

We have quite a few Windows systems, as well, and some of the applications that we used to run on Linux have now been migrated to Windows.

We have a mixed environment, although, in the cluster, our deployment is primarily on-premises. There are some deployments into different cloud providers, depending on the service that we're looking for. However, when we head into the cloud, we tend to go to Product as a Service rather than Infrastructure as a Service or the like. This means that we're less concerned about the underlying operating system and we try to avoid interacting with it as much as possible. So, it is just virtualization in this case.

It started mostly with websites and open source environments overall for development. Now, we are moving into business applications as we are migrating our ERP, which is a cp -r tree, to Linux. We are also migrating the database of SAP to SAP HANA on Red Hat Enterprise Linux. 

We use RHEL versions 7 and 8. There is a bit of version 6 still lying around, but we are working on eradicating that. It is mostly RHEL Standard subscriptions, but there are a few Premium subscriptions, depending on how critical the applications are.

Erik Widholm - PeerSpot reviewer
Sr. Enterprise Engineer at a transportation company with 10,001+ employees

We have warehouse management systems (WMSs) where we run Oracle as our database. The app tier is basically Java. We are using a vendor-supplied Java, and the application itself is managed by the vendor. There are just one-offs here and there, such as utility boxes, but the majority is Oracle and the application that connects to Oracle.

On larger systems, like HANA, we have it deployed physically. On everything else, we have deployed it in a VMware environment. It is all on-premises. While there is some cloud, that is being done by contractors. 

We are on versions 6 through 8. As soon as version 9 gets released to GA, I am going to start working on getting that image ready. Currently, about half our images are on version 8, two-fifths are on version 6, and then version 7 is squeezed in-between.

Paul Monroe - PeerSpot reviewer
CTO at Standard Bank International

We're the largest financial institution in Africa, and we use various operating systems and technologies to achieve typical financial service goals. In the past, we were an ION-centric shop. However, in the past decade, we've been increasingly leveraging Linux's agility compared to traditional Unix operating systems. 

Generally, we deploy by cloud, but we use RHEL on-premise in our data centers and prefer SaaS for infrastructure as a service. Our primary cloud providers are AWS and Azure, and we also use smaller third parties for niche environments.

RHEL is spread across virtually all elements of the institution, including headquarters and various locations on multiple continents. In my environment, it is part of a global trading settlement system. 

The rollout for this particular solution was probably about 250 users of the application running on the initial RHEL. We're a global bank, so the user base is much larger worldwide. Users include business and feature analysts, engineers, and project managers. Our infrastructure engineers were the ones pushing for a switch to RHEL, followed immediately by application engineers.

It is used for our production system. We are running multiple web servers and multiple databases on RHEL operating system platform. We are also running some of our OpenShift containers on it. We have a lot of applications that are running on RHEL versions 5, 6, 7, and 8 in our environment, but the maximum number of applications are running on RHEL 7 and 8.

I worked with different organizations. So, the use case varies from organization to organization. Right now, some of the teams are using it for applications like BI, and then there are a few others that are using it for Websphere, middleware, etc.

In terms of the version, most of them are on 7.9, but there are a few on 8.2 and 8.4 as well.

We use it for core infrastructure services, like package mirrors, configuration management hosts, and proxy requests going to the Internet or as reverse proxies in front of our applications. Our campus management software is delivered via RHEL and applications like Wikis learning platforms.

Almost all machines are running on virtualization. Only a few bare-metal systems exist today. Currently, we are not engaged in any kind of public or hybrid cloud environment.

We are primarily using it for services, such as cloud infrastructure services, for our business. We are working with a Town Council in Bolivia. We provide the environment for deployed applications, and we are using it for the private cloud, Linux server, and applications developed within the company.

Mostly, we use version 7.0. We also have three servers with version 8.5. We are working with everything on-premise. We have a cloud, but most of the cloud is accessible from inside the company. It is not accessible from outside of the company.

I use it for almost everything. I run a company in South Texas and Mexico. We are a cloud service provider, and we have implementations for almost everything. We are using it for websites, virtualization, orchestration, and containers, and we are also using it a lot for telecommunications. We use almost all of its features.

We have many versions. We have versions 8, 9, 9, 9.1, 9.2, etc.

Consultant at a tech services company with 1-10 employees

The primary purpose of any operating system is to run all sorts of applications and databases on servers. We use RHEL to run applications and host containers but not much else. We don't use it for databases, and none of our clients use Red Hat virtualization, so no KBM. We install them onto VMware and use them like Red Hat virtual machines.

I primarily work for banks that tend to have a proper on-premise cloud because the data can't leave the premises. We also work for insurance companies, government, and law enforcement organizations. Most of them use it on a virtualized platform like VMware. Some are hardware installations, and other clients are experimenting with cloud infrastructure. One of the banks we work for has started to build its own cloud to get experience and move specific applications to the cloud.

One client has RHEL deployed across two data centers, which is usually a mirrored setup. In other words, two hardware servers are doing the same thing. It can be active-active or active-passive. The VMs also stretch across two data centers, but it's a Metro cluster, so it's in the same city. I've been working with my current client for a couple of years. Our three-person team manages 250 hardware services and about 400 VMs.

We are still migrating a couple of solutions to Red Hat, so the user base is getting bigger.

I am primarily doing developer enablement for users of Red Hat-based software stacks. Most of my experience for the last five years will be in the context of AWS and Azure. As my customers are primarily cloud-based, they are primarily using the Red Hat repositories hosted with Amazon and Azure.

My customers are primarily DoD, so they are using EL7. We are trying to get them to move in the direction of EL8, but it is a slog.

Infosec IT specialist at a government with 10,001+ employees

We are part of the State Department and use the solution to achieve operational excellence and readiness for the cloud. We think about what the next 20 to 30 years of consular systems infrastructure might look like to build and design for the next 40 years. Not many other companies think beyond a decade. 

The solution was implemented in our environment in 2014. The initial mission is still the same but how we go about it is different. For now, the solution is more for application support and making sure we are following State mandates or executive orders. 

For example, one use case involved planning, designing the implementation, and executing a launch of online passport renewals.

Our environment is moving toward tools that provide automation to remove human error. These are tactical operations and use cases. We currently use SaaS, OpenShift, and Ansible to a limited degree.

Our company uses one of the solution's varieties, mostly CentOS. We are restructuring and moving to the licensed version of RHEL and its derivatives. 

We use both RHEL 7 and 8 mostly in the cloud but also have a small data center where the solution is used on bare metal. Our team does a lot of AIML work where we set up instances to run simulations. 

We are moving a bit into Redshift because we do not have many staff members with containerization or Kubernetes experience.

I use Red Hat to run applications like Apache, MySQL databases, etc. It is suitable for data storage and firewall. I can also measure performance with the SAR tools and do all I need with the Linux stack. I run several server farms, community applications, and more. Multiple teams use it. We have a hybrid setup, but we try to keep the use cases separate for each, so they're not transiting that much.

I'm using Red Hat as an OI solution with some Oracle databases and an FTB server on top of it. I am not using containers in Red Hat. It's solely serving as an OS with direct applications installed on it. We have a few thousand users benefiting from Red Hat indirectly, but only 10 to 20 people work directly with it. I only use Red Hat in one location right now. Previously, I had it deployed in a cluster.

Allan E Cano - PeerSpot reviewer
Sr IT Solution Architect at a wholesaler/distributor with 10,001+ employees

We primarily use RHEL for LAMP stacks. Our deployment is currently on-premises, but if they change their licensing model on the cloud, we might start rolling it out in the GCP. It's used globally in VMware environments. We use it in APAC and AMEA, but the majority of the deployments are in the US. The major platforms that we run on it are PLM environment and digital asset management.

Our shop is what we call out of the box and if it doesn't run on a container out of the box, then we don't run it on a container. So none of our stuff is running containers right now.
