The core components of any HA strategy

In his excellent article in Linux Technical Review #04 Jens-Christoph Brendel proposes a new way how to implement High Availability (HA) in current IT architectures. According to Bendel, modern IT architectures continually gain in complexity. This fact makes it difficult to guarantee availability on a certain level. Nevertheless High Availability is not merely a competitional advantage: for many companies keeping availability levels above 99,999 % per year is a matter of existence. Therefore a few systematic steps should help in planning and implementing high availability in your IT environment. This article shows a possible strategy on how to plan High Availability in the Mobile Cloud environment.


OpenStack on SmartOS

SmartOS is an open source type 1 hypervisor platform based on Illumos, a descendant of OpenSolaris, and developed by Joyent. SmartOS is a live operating system, meaning that can be booted via PXE, USB or an ISO image, and runs entirely from memory, leaving the full space on the local disk to be used for virtual machines. This type of architecture makes SmartOS very secure, easy to upgrade and recover. Given its performances and reliability, in the context of the Mobile Cloud Networking project, SmartOS has been chosen to support telco-grade workloads and provide carrier-grade performances.







OpenStack

[OpenStack](http://www.openstack.org) is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface. OpenStack is the infrastructure management framework that is currently powering [the ICCLab research infrastructure](http://www.cloudcomp.ch/research/foundation/projects/the-init-cloud-lab/).
