亚马逊网络服务现货市场以较低的价格出售过剩的计算能力,并降低了可靠性保证。现货市场的低成本性质导致了工业和科学的广泛采用。然而,使用现货市场的挑战之一是,它是故意不透明的,因此用户对潜在的动态几乎没有了解。在2017年底,现货市场的基础机制发生了重大变化-不再使用投标价格来清除容量,因此定价的波动性大大降低。在本文中,我们回顾了以前的工作,旨在分析变化前和变化后的现货实例市场之间的市场动态差异。然后,我们使用这些分析来突出当前和以前的定价算法的可能属性,包括人为操纵,动态算法调整,以及市场供应,需求和定价的持续趋势。
The Amazon Web Services spot market sells excess computing capacity at a reduced price and with reduced reliability guarantees. The low cost nature of the spot market has led to widespread adoption in industry and science. However, one of the challenges with using the spot market is that it is intentionally opaque and thus users have little understanding of the underlying dynamics. In late 2017, the mechanisms underlying the spot market were significantly altered-no longer are bid prices used to clear capacity and as a result the pricing is much less volatile. In this paper, we revisit prior work with the aim to analyze the differences in market dynamics between the pre-change and post-change spot instance market. We then use these analyses to highlight possible properties of the current and previous pricing algorithms, including artificial manipulation, dynamic algorithm adjustment, and persistent trends in market supply, demand, and pricing.
