Red Hat is the primary sponsor of the Fedora Project, a community-supported free software project that aims to promote the rapid progress of [[free and open-source software]] and content.<ref>{{cite web|url=http://fedoraproject.org/wiki/Overview|title=Overview of Fedora Project|publisher=Fedora Project}}</ref>

==Business model==
Red Hat operates on a [[business model]] based on [[open-source software]], development within a community, professional [[quality assurance]], and subscription-based [[customer support]]. They produce open-source code so that more programmers can make adaptations and improvements.

Red Hat sells subscriptions for the support, training, and integration services that help customers in using their open-source software products. Customers pay one set price for unlimited access to services such as [[Red Hat Network]] and up to [[24/7]] support.<ref>{{cite news | url=http://blog.executivebiz.com/2014/06/draft-red-hat-selects-genesys-cloud-contact-center-solution-to-transform-customer-experience/ | title=Red Hat Selects Genesys Cloud Contact Center Tool to Transform Customer Experience | access-date=July 1, 2014 | archive-date=July 9, 2014 | archive-url=https://web.archive.org/web/20140709011606/http://blog.executivebiz.com/2014/06/draft-red-hat-selects-genesys-cloud-contact-center-solution-to-transform-customer-experience/ | url-status=dead }}</ref>

In September 2014, however, CEO [[Jim Whitehurst]] announced that Red Hat was "in the midst of a major shift from client-server to cloud-mobile".<ref>{{cite web|last=Vaughan-Nichols|first=Steven J.|title=Red Hat CEO announces a shift from client-server to cloud computing|url=https://www.zdnet.com/article/red-hat-ceo-announces-a-shift-from-client-server-to-cloud-computing/|publisher=ZDNet.com|date=September 22, 2014}}</ref>

===Ceph Storage===
Red Hat is the largest contributor to the [[Ceph_(software)|Ceph Storage]] [[Software-defined_storage|SDS]] project : Block, File & Object Storage which runs on industry-standard x86 servers and Ethernet IP as well as ARM, InfiniBand, and other technologies.

Ceph aims primarily for completely distributed operation without a single point of failure, scalable to the exabyte level.

Ceph replicates data and makes it fault-tolerant, using commodity hardware and requiring no specific hardware support. Ceph's system offers disaster recovery and data redundancy through techniques such as replication, erasure coding, snapshots and storage cloning. As a result of its design, the system is both self-healing and self-managing, aiming to minimize administration time and other costs.

In this way, administrators have a single, consolidated system that avoids silos and collects the storage within a common management framework. Ceph consolidates several storage use cases and improves resource utilization. It also lets an organization deploy servers where needed.

===OpenShift===
Red Hat operates [[OpenShift]], a [[cloud computing]] [[platform as a service]], supporting applications written in [[Node.js]], [[PHP]], [[Perl]], [[Python (programming language)|Python]], [[Ruby (programming language)|Ruby]], [[Java Platform, Enterprise Edition|JavaEE]] and more.<ref>{{cite web|url=https://www.redhat.com/openshift/community/faq|archive-url=https://archive.today/20121217180550/https://www.redhat.com/openshift/community/faq|url-status=dead|archive-date=December 17, 2012|title=Redhat.com}}</ref>

On July 31, 2018, Red Hat announced the release of Istio 1.0, a microservices management program used in tandem with the [[Kubernetes]] platform. The software purports to provide "traffic management, service identity and security, policy enforcement and telemetry" services in order to streamline Kubernetes use under the various [[Fedora Linux|Fedora]]-based operating systems. Red Hat's Brian Redbeard Harring described Istio as "aiming to be a control plane, similar to the Kubernetes control plane, for configuring a series of proxy servers that get injected between application components".<ref>{{Cite web|url=https://www.theregister.com/2018/07/31/istio_sets_sail_as_red_hat_renovates_openshift_container_ship/|title=Istio sets sail as Red Hat renovates OpenShift container ship|first=Thomas Claburn in San|last=Francisco|website=www.theregister.com}}</ref> Also Red Hat is the second largest contributor to Kubernetes code itself, after Google.<ref>{{Cite web|title=Grafana|url=https://k8s.devstats.cncf.io/d/9/companies-table?orgId=1|access-date=2021-03-26|website=k8s.devstats.cncf.io|quote=Top 10: Google, Red Hat, VMware, Microsoft, IBM, Huawei, Fujitsu, Intel, CNCF}}</ref>

===CloudForms===
Red Hat CloudForms provides management of [[virtual machine]]s, instances and [[Operating-system-level virtualization|containers]] based on VMware vSphere, Red Hat Virtualization, Microsoft Hyper-V, OpenStack, Amazon EC2, Google Cloud Platform, Microsoft Azure, and [[Red Hat OpenShift]]. CloudForms is based on the [[ManageIQ]] project that Red Hat open sourced. Code in ManageIQ is from the over {{US$|100&nbsp;million}} acquisition of ManageIQ in 2012.<ref>{{Cite web|url=https://access.redhat.com/products/red-hat-cloudforms|title=Red Hat CloudForms|website=Red Hat Customer Portal}}</ref><ref>{{Cite web|url=https://www.redhat.com/en/investors|title=Red Hat Investor Relations|website=www.redhat.com}}</ref>

===CoreOS===
Container Linux (formerly CoreOS Linux) is a discontinued open-source lightweight operating system based on the Linux kernel and designed for providing infrastructure to clustered deployments. As an operating system, Container Linux provided only the minimal functionality required for deploying applications inside software containers, together with built-in mechanisms for service discovery and configuration sharing.

===LibreOffice===
Red Hat contributed, with several software developers, to [[LibreOffice]], a [[free and open-source]] [[office suite]].<ref>{{Cite web|url=https://fedoraproject.org/wiki/Red_Hat_contributions#LibreOffice_developers|title=Red Hat contributions - Fedora Project Wiki|website=fedoraproject.org}}</ref> However, in 2023, Red Hat announced they were not going to include LibreOffice in RHEL 10, citing the ability to download LibreOffice from [[Flatpak]] on RHEL desktops.<ref>{{Cite web|url=https://www.theregister.com/2023/06/07/red_hat_drops_libreoffice/|website=The Register|publisher=Situation Publishing|title=Red Hat to stop packaging LibreOffice for RHEL|date=2023-06-07|author-last1=Proven|author-first1=Liam}}</ref>

Red Hat made the most acquisitions in 2000 with five: Cygnus Solutions, [[Bluecurve]], Wirespeed Communications, Hell's Kitchen Systems, and [[C2Net]]. On June 5, 2006, Red Hat acquired [[Open-source model|open-source]] middleware provider JBoss for {{US$|420&nbsp;million}} and integrated it as its own division of Red Hat.
