More than two years after the start of one of the largest projects in which Univention has been involved to date, a new mail platform with over 30 million managed end users finally went online in late 2016. UCS takes care of the identity management duties for all the user accounts.
I first reported on the challenges of the project almost a year ago in the article How can OpenLDAP with UCS be scaled to over 30 million objects?. However, it is now no longer a “gray theory” – the project has now gone live and the LDAP has had to cope with the strain of thousands of accesses every second in real time ever since.
Today, I would like to provide you with an update and share with you some of our most important findings from the going live process.
