Open source solutions provider, Red Hat, has announced the general availability of Red Hat Enterprise Linux 7 Atomic Host, an operating system optimized for running the next generation of applications with Linux containers. Red Hat Enterprise Linux 7 Atomic Host would provide all of the components necessary to easily package and run applications written for Red Hat Enterprise Linux 6 and 7 as containers.
As monolithic stacks give way to applications comprised of micro-services, a container-based architecture can help enterprises to more fully realize the benefits of this more nimble, composable approach. Red Hat Enterprise Linux 7 Atomic Host would enable enterprises to embrace a container-based architecture, reaping the benefits of development and deployment flexibility and simplified maintenance, without sacrificing performance, stability, security, or the value of Red Hat’s vast certified ecosystem.
Red Hat is committed to offering enterprises a complete and integrated container-based infrastructure solution, combining container-based application packaging with “robust”, optimized infrastructure that would enable easy movement of Red Hat Enterprise Linux-certified applications across bare metal systems, virtual machines and private and public clouds – all of this with the product and security lifecycle that enterprise customers require.
For building and maintaining container infrastructure, Red Hat Enterprise Linux 7 Atomic Host’s benefits would include:
- Atomic updating and rollback through an image-like update mechanism. An atomic update can be downloaded and deployed in a single step, while the previous version is retained, allowing for easy atomic rollback, if necessary.
- Container images in docker format can be deployed and run as application containers.
- Certification and support, along with a chain of trust for containers built using platform images provided by Red Hat, such as Red Hat Enterprise Linux 6 and 7 and certified containers from Red Hat’s independent software vendor (ISV) partners.
- Container orchestration at scale through Kubernetes, creating large-scale business applications from discrete services deployed in containers across clusters of Red Hat Enterprise Linux 7 Atomic Host.
- Stronger security by default through SELinux, cgroups and kernel namespaces, isolating each container in a multi-container environment.
- Support for super-privileged containers enables host management applications to access the host and other containers in a secure manner. This specialized container provides users with the means to install third party software and the atomic command inherent to Red Hat Enterprise Linux 7 Atomic Host makes creating and running super privileged containers dramatically easier.
- Application portability across the open hybrid cloud by leveraging Red Hat’s vast certified ecosystem, enabling secure, stable container deployments on physical hardware, on certified hypervisors including Red Hat Enterprise Virtualization, VMware and Microsoft Hyper-V, and on certified public cloud services like Amazon Web Services and Google Cloud Platform.
