RHEL 7.2 new cool stuffFrom my perspective :-)
● Red Hat Enterprise Linux Server for ARM 7.2 Development Preview, ● first made available to partners and their customers, this Development Preview
enables new partner hardware and additional features for the ARM architecture.
● Red Hat Container Development Kit 2 Beta,● a collection of images, tools, and documentation to help application developers
simplify the creation of container-based applications that are certified for
deployment on Red Hat container hosts, including Red Hat Enterprise Linux 7.2, Red
Hat Enterprise Linux Atomic Host 7.2 and OpenShift Enterprise 3.

WHAT ARE LINUX CONTAINERS?
Software packaging concept that typically includes an application and all of its runtime dependencies.
● Easy to deploy and portable across host systems
● Isolates applications on a host operating system
● In RHEL, this is done through:
– Control Groups (cgroups)
– kernel namespaces
– SELinux, sVirt
– Docker

● Will what’s inside the containers compromise your infrastructure?
● How and when will apps and libraries be updated?
● Will it work from host to host?
RED HAT CERTIFIED
● Trusted source for the host and the containers
● Trusted content inside the container with security fixes available as part of an enterprise lifecycle
● Portability across hosts

Atomic updating and rollback means it’s easy to deploy, update, and rollback using imaged-based technology.
Build composite applications by orchestrating multiple containers as microservices on a single host instance.
Atomic Host - a container-optimized, minimal footprint OS powered by Red Hat Enterprise Linux
Atomic Telemetry - logging and metrics for pods/containers, services and underlying infrastructure to make informed decisions
Atomic Runtime and Packaging Format - standardized container packaging format and runtime, powered by Docker (and OCI)
Atomic Automation and host configuration management via Cockpit to dynamically provision and configure container host clusters
Atomic Orchestration - for complex multi-container services, powered by Kubernetes
Atomic Networking - scalable, multi-host container networking, powered by Open vSwitch, that runs anywhere Red Hat Enterprise Linux runs
Atomic Cluster Services - Scheduling for services across a container host cluster, powered by Kubernetes
Atomic Storage, with persistent storage plugins to enable running of stateful services in containers
Atomic Registry - integrated storage and management for sharing container images
Atomic Security to prevent tenants from compromising other occupants
Optimized container infrastructure solution for deploying, running, and managing distributed applicationsRed Hat Atomic Enterprise Platform
Overview
OpenShift is Red Hat’s Container Application Platform
● Built for both traditional and cloud-native applications.
● An integrated hybrid cloud application platform for application development and deployment
● Develop, build, and manage container based applications
● Easily turn source code into running applications with source-to-image capabilities
Critical features for both Dev and Ops
