What is Red Hat Enterprise Linux (RHEL)?
Red Hat® Enterprise Linux® is the world’s leading enterprise Linux platform. It is the intelligent operating system for bare metal, virtual machine, and cloud deployments, both on and off premise, providing a consistent foundation that enables multicloud application deployments.
Through control, confidence, and freedom, Red Hat Enterprise Linux reduces the friction and cost of change, while increasing agility and reducing the time to market for critical business workloads.
Customers can focus on business growth instead of reacting to security vulnerabilities and costly management configuration mistakes.
Customers can operate with the confidence that comes from running critical revenue-generating workloads on a proven, reliable, and high-performing foundation.
FREEDOM TO INNOVATE
Customers can develop, deploy, and maintain their applications with developer tools on any infrastructure they choose.
Red Hat Insights
Red Hat Insights is now included in every Red Hat Enterprise Linux subscription. Red Hat Insights helps IT teams proactively identify and remediate threats to security, performance, availability, and stability to avoid issues, outages, and unplanned downtime and to ensure their Red Hat environment is operating optimally. No other Linux provider offers proactive and targeted resolution to ensure a secure, reliable, efficient, and scalable infrastructure environment.
Application streams resolve the challenge of getting the most up-to-date language and frameworks for developers without compromising RHEL production stability. With application streams, fast-moving languages, frameworks, and developer tools can be updated frequently without impacting core resources.
Web console is the new Red Hat Enterprise Linux browser-accessible user interface designed to lower the barrier of entry for clients new to Linux by making system administration management and monitoring tasks easier.
System roles are pre-configured Ansible roles that enable ready-made automated workflows for handling common, complex system administrator tasks around managing and configuring Linux in production. They are designed to increase the creation of automation to help eliminate human error as the cause of common configuration issues.
Cryptographic protection can be implemented system-wide with a single command, limiting the need for application-specific policies and tuning.
Container toolkit provides technologies for creating, running and sharing containerized applications based on open standards.
Image builder creates blueprints for operating system images. Operators can easily create consistent images in hybrid environments.
Universal base image
Red Hat Universal Base Images (UBI) are OCI-compliant container based operating system images with complementary runtime languages and packages that are freely redistributable. Like previous RHEL base images, they are built from portions of Red Hat Enterprise Linux.
Red Hat Enterprise Linux continues to support larger systems that our customers may grow into, giving customers the right solution for their present and the future.
IT staff needs to spend as much time as possible guiding critical projects and otherwise helping the business grow, rather than spending copious amounts of time dealing with outages and administrative tasks.
RHEL enables the IT staff to:
- Drive critical business and application workloads
- Spend 82% less time dealing with server downtime issues
Few IT environments these days run one single operating system; many of our customers also have, for example, Microsoft Windows servers in their environments.
Enabling customers to leverage and extend their existing environments, Red Hat Enterprise Linux (RHEL) uses industry standards to interoperate with other systems and vendors, such as the following:
- Container tools compliant with Open Container Initiative standards
- Active Directory (Microsoft) and LDAP
- Shareable network file systems compatible with other operating systems
- Native support of many enterprise software suites, e.g., SAP, SQL Server, and Oracle
- Red Hat Enterprise Linux includes many native administrative tools:
- Software and update management
- User management
- Disk and storage management
- Remote administration
- Red Hat Insights analytics and analysis
- And others..
Red Hat Enterprise Linux (RHEL) is a foundation on which high performance applications or workloads can be run. Customers choose Red Hat Enterprise Linux (RHEL) for it’s performance. Red Hat is commonly associated with record-breaking benchmarks in the industry:
- 35 world records for performance using Red Hat Enterprise Linux on the Intel Xeon processor.
- Routinely used on the world’s fastest supercomputers.
Red Hat Enterprise Linux’s 10-year lifespan provides a long-term, stability for enterprises. This means customers are not forced to continually upgrade. Rather, the 3-year major and 6-month minor release cadences offer predictability. The customers can predictably see the life cycle of a release and upgrade as their business needs require.
Other business benefits to the 10-year life span feature include:
- Investment protection
- Business continuity (up time)
Customers don’t need to continually update and/or recertify applications, which protects their most important assets that are their business rules residing in their applications. At the same time, it reduces cost and effort to do those periodic application certifications and/or updates, which also implies less downtime.
RHEL provides longer release support than most Linux distributions. A Red Hat Enterprise Linux subscription can be used to deploy any supported version, enterprises can choose when to deploy newer versions.
In addition to the Red Hat Product Security team (covered later in this module), Red Hat Enterprise Linux includes many native security features, such as:
- Security-Enhanced Linux (SELinux)
- FIPS 140-2 security certification
- Security Content Automation Protocol (SCAP) applications and tooling
- System-wide cryptographic policy management
RHEL also includes a number of security tools such as the following that can be used to increase the overall security of systems without additional purchases.
- IdM: Identity Management
RHEL offers the ability to move from physical environments to virtual, cloud environments, and containers.
RHEL can be deployed many different ways:
– Physical (Bare Metal): Running as the operating system directly on customer hardware.
– Virtual: Deployed as a guest operating system on virtualization infrastructure.
– Public Cloud: Run as an operating system instance on a public cloud provider.
– Private Cloud: As an operating system instance in a private cloud deployment.
