摘 要:隨著云服務提供商對業務模式的不斷探索,云市場逐漸成為了其構建云生態、向平臺型提供商轉型的重要戰略措施。云市場具有兩種類型:非資源型云市場(RLCM)只提供軟件即服務(SaaS)的交易平臺業務;資源型云市場(RFCM)在平臺業務的基礎上,還提供SaaS所需的基礎架構(IaaS/PaaS)資源。本文聚焦于兩類平臺的競爭問題,探究了RFCM對本地部署的SaaS所采用的阻止/許可策略以及兩類平臺的定價決策問題。研究表明,只有當IaaS/PaaS資源的單位成本足夠高且RFCM具有明顯價值優勢時,許可策略才可能是RFCM的占優策略,并且當RFCM采用許可策略時,RLCM會設置更低的入駐費來應對競爭。本文旨在為不同類型的云市場進行競爭時如何選擇最佳的價格及服務差異化策略提供理論依據。

Abstract:To host a cloud marketplace has become a strategic plan of cloud service providers (CSPs) to establish their cloud ecosystems and transform themselves into platform CSPs. The resourceful cloud marketplace (RFCM) offers both trading platform of software services (SaaS) and the required infrastructure (IaaS/PaaS) to independent software vendors (ISVs), while the resourceless cloud marketplace (RLCM) only offers a trading platform. This paper focuses on the competition between RFCM and RLCM and studies RFCM’s Deter/Allow strategy for ISVs who implement SaaS via either the in-house infrastructure or the IaaS/PaaS of an RFCM. It is demonstrated that RFCM’s dominant strategy is mainly affected by the unit cost of IaaS/PaaS resources and the value difference between the two marketplaces. Moreover, when the RFCM adopts the allow strategy, the RLCM tends to reduce the entry fee in the competition. This paper provides theoretical guidance for competitive platform CSPs to make decisions for pricing and service differentiation strategies.Key words:cloud service; cloud marketplace; collaborative supply; platform openness; competition

云計算為企業及個人用戶提供了一種高效、便捷的計算資源獲取方式。隨著云計算理論與技術的日趨成熟,越來越多的用戶將其線下計算業務遷移到云端。我國大力倡導發展云計算業務,在2015年國務院出臺的《關于積極推進“互聯網+”行動的指導意見》(國發〔2015〕40號)以及2020年國家發展改革委和中央網信辦制定的《關于推進“上云用數賦智”行動培育新經濟發展實施方案》(發改高技〔2020〕552號)中,均指出了云計算在國家重大產業布局以及促進產業轉型升級中的重要作用。近年來全球新冠疫情的爆發,更是加快了企業上云的步伐,極大地促進了云服務產業的發展。……
