Red Hat Enterprise Linux and Ansible Tower by
Red Hat help British Army improve consistency and simplify
management
Red Hat, Inc. (NYSE:RHT), the world's leading provider of open
source solutions, today announced that the British Army has
migrated its private cloud environment to Red Hat Enterprise Linux
and is using Ansible Tower by Red Hat for automation and
orchestration. With Red Hat Enterprise Linux and Ansible Tower by
Red Hat, the British Army is able to deliver applications more
quickly and efficiently, with less downtime, to better meet the
needs of end users.
Headquartered in Andover, UK, the British Army has more than
19,000 soldiers deployed in commitments, in more than 27 countries
across the globe. The Army’s Information Application Services (IAS)
team delivers large corporate applications, hosting and web
services that provide support to military families, veterans and
more. The IAS team has applications in production running on two
main hosting environments: a joint server farm hosted in a private
cloud, and a private hosting environment, which consists of two
private clouds designated for secure data.
The IAS team was experiencing support and compatibility issues
with the legacy stack, resulting in unplanned downtime for upgrades
and delayed updates. The Army sought a solution that could not only
deliver software more quickly and without downtime, but would also
enable them to embrace DevOps methodologies.
As a result, the British Army migrated to Red Hat Enterprise
Linux and moved from a physical infrastructure to a
software-defined datacenter. Its main stack consists of five
database servers and two applications servers, all of which have a
central spine of a clustered file system. For this, the Army uses
the Resilient Storage add-on for Red Hat Enterprise Linux, which
offers robust file system capabilities that enable users to access
the same storage device over a network—using either shared storage
or a clustered file system—through a pool of data that's available
to each server in a group.
To help with management, the Army deployed Ansible Tower by Red
Hat, initially using the enterprise-grade agentless automation
platform to automate the installation of routine patches and
configuration updates to Red Hat Enterprise Linux. The British Army
has expanded its Ansible Tower implementation, now using it to
provide rapid patching and system reconfiguration for urgent
requirements, and to provide other DevOps functionality for routine
system administration.
With the new Ansible automation-based system, the Army has
accelerated its pace of change by 75 percent. Upgrades that used to
take a day can now be achieved with high availability in less than
two hours, and can be scheduled after hours. Emergency patches that
used to take approximately three days can be implemented in a
matter of hours. Overall, delivering changes is now four times
faster, on average, based on the British Army’s internal
calculations. With the time saved from automating tasks with
Ansible Tower by Red Hat, the Army has been able to reallocate
people to other parts of the organization.
The Army plans to extend the DevOps capability provided by
Ansible, to include other platforms, as well as managing its
network switches and servers.
Supporting QuotesLt Col. Dorian Seabrook, head of
Operations, IAS Branch, British Army“We want to deliver software
quicker and more efficiently to meet the end users’ requirements
and we absolutely made the right choice with Ansible. It works for
us on a number of levels, and the adoption throughout the
organization is now starting to really take hold. Previously,
communicating the delivery timescales for large projects could be
quite stressful. Now, in most cases, we’re delivering quicker than
the users can actually absorb the changes. Our users are just
staggered by the agility and the turnaround time and what we can
now offer them.”
Joe Fitzgerald, vice president, Management, Red Hat“The British
Army, like many organizations, is under constant pressure to
deliver software and services quickly with no downtime. An
increasingly large challenge IT organizations are facing is to
modernize software development and IT operations while still
operating and maintaining traditional applications and
infrastructure. To keep up with the requests from its users, the
British Army decided to enhance its DevOps capabilities by
deploying Ansible. At the press of a button, Ansible Tower can
deliver software and updates to the correct places, which can lead
to fewer errors and help eliminate unplanned downtime.”
