January 2027 alone ends Windows Server 2016, .NET Framework 4.6.2, BizTalk 2016, System Center 2016 and TFS 2017. Then PostgreSQL 14 on RDS, Node.js 22, Ubuntu 22.04, Python 3.11, SQL Server 2017, PostgreSQL 15, PHP 8.3 and the EU's CRA and AI Act. The whole year, month by month, for planning budgets now.
Most teams track one vendor's calendar. The work collides across vendors: the Windows server, the SQL Server under it, the .NET Framework app on it and the Node.js front end beside it can all need upgrading in the same quarter. Every 2027 date is below, in one table.

Checked against each vendor's published schedule in October 2026. EKS version dates are in our EKS deadlines post.
Map every system to the rows above. Most estates hit five to ten of them.
Group by application, not by vendor: the server, database, runtime and framework of one application upgrade together, once.
Front-load January. The Microsoft cluster is the largest single block and the hardest to buy time for.
Budget now. Extended Support and ESU charges that start in 2027 belong in the 2027 budget, and so does the work to avoid them.
Once a month: what changed in tech that month and what it means for you, from cloud and AI to security and the tools you build with. Every item links to its source. No sales pitch, unsubscribe in one click.
Book a free 30-minute call about it. Bring your setup and your bill; you'll leave knowing what we'd do first and roughly what it costs, whether or not you hire us.
