Ubuntu is the basis for the majority of cloud-based workloads today. With over 450 million public cloud instances launched since the release of Ubuntu 16.04 LTS, a number that keeps accelerating on a day-per-day basis since, many of the largest web-scale deployments are using Ubuntu. This includes financial, big data, media, and many other workloads and use cases, which rely on the stability and continuity of the underlying operating system to provide the mission-critical service their customers rely on.

Extended Security Maintenance (ESM) was introduced for Ubuntu 12.04 LTS as a way to extend the availability of critical and important security patches beyond the nominal End of Life date of Ubuntu 12.04. Organisations use ESM to address security compliance concerns while they manage the upgrade process to newer versions of Ubuntu under full support. The ability to plan application upgrades in a failsafe environment continues to be cited as the main value for adoption of ESM. With the End of Life of Ubuntu 14.04 LTS in April 2019, and to support the planning efforts of developers worldwide, Canonical is announcing the availability of ESM for Ubuntu 14.04.

What did we learn from Ubuntu 12.04 Extended Security Maintenance?

Ubuntu 12.04 was the first Long Term Support version of Ubuntu to receive an Extended Security Maintenance. This couldn’t come at a better time, as in the last year IT departments have had to deal with major IT security and compliance issues: GDPR, Spectre, Meltdown, Stack Clash, Blueborne, Dirty Cow, SegmentSmack or FragmentSmack to name a few. In total ESM has provided over 120 updates, including fixes for more than 60 high and critical priority vulnerabilities, for Ubuntu 12.04 users.

Extended Security Maintenance gives the opportunity for IT, devops and security teams to take on a new approach to their OS update strategy:

ITstrategen used Extended Security Maintenance to guarantee the continued security of its servers and saving its clients from costly application updates.
