INTELLIGENT BRANDS // Data Centres support for the Elastic Network Adapter (ENA) on Amazon Web Services (AWS) to enable new network capabilities. Linux Containers and Red Hat Enterprise Linux Atomic Host Linux containers present an evolution in how businesses develop, deploy, and manage modern applications, helping enterprises scale to new levels of operational efficiency, speed application development and drive increased flexibility in managing application life cycles. Based on Red Hat Enterprise Linux 7.4, the latest version of Red Hat Enterprise Linux Atomic Host further refines enterprise-grade Linux containers with enhancements that include: Jim Totton, vice president and general manager, Platforms Business Unit, Red Hat secure the underlying file system and provides the ability to use docker and namespaces together for fine-grained access control. Improved security without sacrificing performance, thanks to integrated support for SELinux and OverlayFS, as well as full support for the overlay2 storage graph driver. Full support for package layering with rpm-ostree, providing a means of adding packages like monitoring agents and drivers to the host operating system. Performance Modern business applications require more bandwidth and increased storage, placing a performance strain on traditional operating systems and hardware. Engineered to meet the needs of organisations seeking to both modernise and optimise their enterprise IT infrastructure, Red Hat Enterprise Linux 7 offers new features designed to improve the performance of both networking and storage. New features include: Support for NVMe Over Fabric helps to provide customers with increased flexibility and reduced overheads when accessing high performance NVMe storage devices located in the data centre on both Ethernet or Infiniband fabric infrastructures. Other features include general enhancements to Red Hat Enterprise Linux’s performance when deployed on the public cloud, highlighted by decreased boot times to better enable mission- critical applications to start sooner, and 56 INTELLIGENTCIO “Red Hat Enterprise Linux 7.4 offers new automation capabilities designed to limit IT complexity while enhancing workload security and performance for traditional and cloud-native applications.” The introduction of LiveFS as a Technology Preview, which enables users to install security updates and layer packages without a reboot. Management and automation With datacentre footprints that span from bare-metal to the cloud, the complexity associated with controlling IT environments continues to increase. Complementing the capabilities of Red Hat Satellite and automation via Ansible Tower, Red Hat Enterprise Linux 7.4 introduces Red Hat Enterprise Linux System Roles as a Technology Preview. System Roles provide a common management interface across all major versions of Red Hat Enterprise Linux, enabling an automated workflow via Ansible automation to be created once and used across large, heterogeneous Red Hat Enterprise Linux deployments without additional modifications. Red Hat Enterprise Linux for multiple architectures Red Hat remains committed to providing customer choice when it comes to datacentre infrastructure. Red Hat Enterprise Linux 7.4 maintains this commitment with availability across multiple architectures, including IBM Power, IBM z Systems and 64-bit ARM (as a Development Preview). For the IBM Power Little Endian architecture, this release enables support for the High Availability and Resilient Storage Add-Ons as well as the Open Container Initiative (OCI) runtime and image format. Jim Totton, vice president and general manager, Platforms Business Unit, Red Hat, said: “The modern enterprise will not be solely based in physical servers or cloud services; rather, the path to digital transformation weaves across four distinct technology footprints. The latest version of the world’s leading enterprise Linux platform supports each of these deployment methodologies with new security features, improved performance and introduces new automation capabilities to cut through the inherent complexities of heterogeneous datacentres.” n www.intelligentcio.com
