Red Hat® Enterprise Linux® is an operating system based on the Linux kernel. It is a popular choice for professional applications due to its advantages, including:
- RHSM (Red Hat Subscription Manager) subscription channels that provide access to curated open-source software with a guarantee of consistent interfaces throughout the release cycle;
- The Red Hat Errata mechanism, which ensures operational security through rapid updates throughout the software’s lifecycle;
- Technical support and the SOS Report tool, which guarantee effective assistance for issues with hardware (drivers) or software;
- Thanks to practical, performance-based RHCE (Red Hat Certified Engineer) certification, specialists with deep and up-to-date knowledge of Red Hat systems are consistently available on the market;
- RHEL is chosen by leading manufacturers as the reference operating system for hardware, services, and software.
Red Hat® OpenStack® is the most popular open-source solution that enables a cloud computing model while maintaining full control over your own on-premise infrastructure.
The platform places a strong emphasis on operational security and the ability for users to be billed for computational resource usage in real time. At the same time, it gives them the freedom to allocate new virtualized infrastructure components on the fly, according to their current needs.
Thanks to the open-source nature of the software, it’s possible to choose from various OpenStack distributions depending on a client’s needs. This also protects the investment by avoiding vendor lock-in.
The IaaS (Infrastructure as a Service) paradigm allows for the use of many existing, mature solutions:
- SDLC (Software Development Life Cycle) automation and management;
- Automated software testing and deployment in line with CI/CD (Continuous Integration/Continuous Deployment);
- Baseline patterns that ensure repeatability and security during the change process;
- Tools that increase work efficiency following DevOps culture..
Red Hat® OpenShift® is a reference implementation of the PaaS (Platform as a Service) model based on the Kubernetes framework, which has become the de facto standard for solutions using Docker container architecture.
OpenShift is built on the open-source OKD project, and its foundation is based on the Docker, Kubernetes, RHEL, and Tectonic projects. This choice of technologies ensures reliability, continuous development, and eliminates the risk of choosing a closed, non-standardized solution.
OpenShift orchestrates, load balances, and ensures high availability (HA) of containers. It also:
- Provides a complete commercial solution that allows for the deployment, versioning, storage, and production release of source code according to best practices, while maintaining isolation and security at the system, network (SDN), and application layers.
- Makes it easy to integrate proven solutions delivered directly as containers, such as an integrated CI/CD system (Jenkins), a Service Catalog, metrics subsystems (Hawkular, Prometheus), log aggregation (Elastic, Fluent, Kibana), or distributed and software-defined storage (SDS, based on Gluster FS).
- Offers a granular set of permissions (RBAC), plugin-based authentication (including LDAP, OAuth), namespace separation using a “project” mechanism, and a web console that allows for the secure deployment of Instant Apps without requiring specialized knowledge of container architecture.
- Enables a zero-downtime update process, allowing for both minimal resource unavailability (rolling update) and minimization of the upgrade process itself (blue-green update).
- Delivers certified container images for many popular open-source solutions and development platforms, which have Red Hat support and are covered by the Red Hat Errata security update mechanism.
Red Hat® Ansible® Automation Platform is currently the most widely used automation platform, helping to save time and eliminate one-off issues. Ansible solves a range of repetitive problems, such as provisioning systems (physical, virtual, and cloud-based), deploying applications, and orchestration. This is possible through managing shared infrastructure components and maintaining compliance with security standards.
Additionally, the optionally installed Ansible Tower software extends the IaC (Infrastructure as Code) paradigm to the corporate world. Ansible Tower complements the Ansible ecosystem with functionalities most often required in production environments, such as: centralized logging, secret management, role-based access control (RBAC), the ability to run tasks periodically (Configuration Management), high availability (HA), and an available REST API.
Automation: Ansible automates the configuration of Linux-based servers, but also Windows and macOS servers, and supports a wide range of network devices.
Simplicity: Writing automation in YAML defines the tasks to be performed while also documenting the infrastructure’s structure and behavior.
Flexibility: The available modules (over 2000 modules available out-of-the-box), plugins, and the Ansible Galaxy system allow for quick automation of popular solutions.
Agentless: Ansible was the first to operate in a “push” model and use existing SSH connections. Managing a server with Ansible doesn’t require prior configuration or running additional system services. Being agentless increases security, doesn’t consume resources, and makes it easier to understand how the automation system works.
Red Hat® JBoss® EAP is an open-source platform for running modern Java applications in various environments: bare metal, virtual, cloud (public, private, hybrid). It offers advanced enterprise-grade features such as: advanced management, automation, high-availability clustering, distributed caching, messaging, transactions, web services, and many more.
The platform has a flexible, modular architecture with service-based components. It is an excellent environment for a variety of Java applications: traditional, web-based, and microservices-based. It is also adapted to work with OpenShift, which opens up broad opportunities to use the best DevOps and CI/CD (Continuous Integration/Continuous Delivery) practices.
JBoss EAP’s performance is tailored for building and deploying highly transactional applications. Using JBoss improves flexibility and scalability, reduces IT complexity, and lowers maintenance costs while meeting security and regulatory compliance requirements.
JBoss EAP supports many popular Java EE web frameworks, including Spring, Spring Web Flow, Spring WS, Spring Security, Arquillian, AngularJS, jQuery, jQuery Mobile, and Google Web Toolkit (GWT).
Red Hat® Satellite® provides a central management point for Red Hat® Enterprise Linux® (RHEL) servers.
Red Hat Satellite allows for comprehensive infrastructure management in various areas:
- Content Management,
- Configuration Management,
- Provisioning of new servers,
- Software Deployment Life Cycle,
- Security Audit and Remediation of system compliance.
Configuration management is based on Ansible and Puppet software. By using modules (roles) provided by Red Hat and the community, operators can configure ready-made operating system components and server services based on several thousand modules (roles) available via Ansible Galaxy and Puppet Forge.
Content and subscription management has been significantly simplified compared to Red Hat Satellite 5. The new Red Hat Satellite 6 system allows for easier license management based on activation keys, enabling the creation of functional sub-units to track license resource utilization. In addition, the process of managing content (repositories) provided by Red Hat has been improved. It is now possible to choose specific operating system versions and add-ons by navigating a clear tree structure.
The administrative console includes a dashboard that shows the status of registered agents (RHEL servers), synchronization (downloading Red Hat and third-party repositories), and Dynflow tasks (e.g., classifying and publishing Content Views or applying Red Hat Errata patches).
A built-in mechanism for tracking operating system compliance with established policies, based on OpenSCAP, is also available to administrators. It is possible to scan according to standard policies (including PCI DSS 3, NIST), view reports graphically using the Red Hat Satellite interface, and automatically restore systems to a policy-compliant configuration (remediation) using automated configuration scripts or a remote access mechanism (Remote Execution).
An optional Red Hat Insights license is also available, which provides contextual advice on service configuration.
