About Sjak Verlangen


FinOps Domain Lead

As FinOps Domain Lead for Atos, Sjak currently dedicates his attention and professional skills to controlling and optimizing cloud costs for his clients. He recognizes that consuming resources in the public cloud has become relatively quick and easy, but these convenient resources come with a “forever” cost. Although these public cloud costs are usually very transparent, they are also very complex - so understanding the cost details, allocation requirements and differences between public cloud platforms requires the knowledge, skills, experience and dedication he brings together in his role. Sjak gets great satisfaction in solving cloud cost challenges for clients that are incurring monthly costs in the thousands, or even millions, and has helped reduce those costs by as much as 50%! He is a creative but pragmatic problem-solver - a combination developed through more than 15 years of experience in IT cost modeling and applications to business cases.

When he isn’t reducing cloud costs for Atos clients, Sjak’s priority is achieving a good work - life balance. He enjoys a good laugh as well as deeper discussions about bigger life and global issues. His home is in Sint-Michielsgestel (NL), where he lives with his wife.
