Your applications and data reside on a high-performance server farm in a high-security data center. They connect via the Internet and work from this point on really directly on the server. Since you work directly on the server, the performance of your PCs and notebooks plays only a minor role and thus the use of low-cost laptops and PCs, even old used hardware is possible. This and a lot of other advantages with up to 50% reduced costs can speak in favor of this solution.
