Windows Server 2012/2012 R2 and SQL Server 2012 are now out of support but it’s possible to purchase Extended Security Updates licences to receive security updates for a further three years for these products. The idea of ESUs isn’t new, but what IS new is that 1-year ESUs are now available through CSP (rather than just an EA/EES) and there’s a new PAYG option for ESUs through Azure Arc. This is a great page to learn more: https://bit.ly/3QBfgnn, and to get links to further information.
