云资源成本优化与浪费削减策略

在云计算环境中，有效管理成本和减少资源浪费是至关重要的。本文将介绍一些实用的方法和策略，帮助你优化云资源使用，降低成本。

1. 数据库成本测试

首先，我们来看一个数据库成本测试的例子。给定以下参数：

HOURS_IN_MONTH = 730
MONTHLY_BUDGET = 5000
DATABASE_COST_PER_HOUR = 5
NUM_DATABASES = 2
BUFFER = 0.1

def test_monthly_budget_not_exceeded():
    total = HOURS_IN_MONTH * NUM_DATABASES * DATABASE_COST_PER_HOUR
    assert total < MONTHLY_BUDGET + MONTHLY_BUDGET * BUFFER

对于以下问题：
Which are true? (Choose all that apply.)
A. The test will pass because the cost the database is within the budget.
B. The test estimates the monthly cost of databases.
C. The test does not account for different database types.
D. The test calculates the monthly cost per database i
