The total cloud expenditure for the following month can be calculated by adding the costs of storage, compute, and network. However, since the network team has established a new connection to an IaaS CSP that is more efficient and has networking costs that are 25% less than previous monthly expenditures, the network cost for the following month will be reduced by 25%. Therefore, the network cost for the following month will be $7000 x (1 - 0.25) = $5250. The total cloud expenditure for the following month will be $10000 + $12000 + $5250 = $26250.
