The Government Is Building Its Own Cloud: What This Means and Why It Matters to You

19 October 2026

Three companies—Google, Amazon and Microsoft—together account for 70% of the European cloud market. European providers each hold a market share of approximately 2%.

The Enterprise Chamber ruled that the TOR had no right to be consulted on the decision to treat the reorganisations at DISA and the Immigration and Naturalisation Service (IND) as separate processes, without transferring personnel between them. According to the Enterprise Chamber, the decision concerned the allocation of public-law responsibilities between government services and therefore fell within the scope of the political primacy principle set out in Article 46d of the Dutch Works Councils Act (Wet op de ondernemingsraden, or WOR). Notably, however, the Enterprise Chamber described the decision-making process as “highly careless”. This finding did not lead to a different legal conclusion.
