5. Discussion and Implications
5.3 Implications and Suggestion
According to the above discussion of the research result and research limitations, we would like to make some suggestions. First of all, we suggest that the IaaS service providers should put a high premium on the education of their customers, especially the IT managers in the public sectors, about the benefits and advantages to improve the efficiency and quality of service of their departments. If they want to expand their IaaS market, it is easier to begin with one of the government agencies that have a perceived higher IT knowledge capability. Moreover, it is
worthwhile to put more time and effort into promotion activities to improve customers’ willingness to adopt IaaS.
For future researchers, we would like to suggest them to incorporate more other enabling factors or hindering factors into their research framework, for example, perceived risk or
implementation complexity, to test whether these factors can negatively affect the intention to adopt IaaS. Besides, since there may be some inexperienced users being our respondents, future research can be conducted on experienced users of IaaS. Furthermore, a better sampling plan is also
recommended. They can separate the samples of central government agencies from those of local government agencies since their decision powers might be totally different. This may be very important for future researchers to answer the related questions more correctly. The items of the questionnaire should also be chosen or designed more carefully. For example, they can add some negative items or adapt items from more suitable resources. Lastly, future researchers could consider incorporating more government-specific characteristics and thinking of more IaaS adoption scenarios for government agencies into their framework to fit in more with the research context. According to some studies, managers from public sectors perceive more emphasis on rules, channels, and procedures, and more constraints on authority. For instance, they can respectively talk about the adoption of different types of IaaS, that is, public IaaS, private IaaS, or hybrid IaaS.
Different types of IaaS may lead to totally different results. Therefore, we suggest that they must take this factor into account in their studies.

※ 雲端運算中「 基礎設施即服務(IaaS) 」 簡介:
雲端運算是近幾年來資訊相關產業與報章雜誌上最夯的用語,已有許多資訊大廠 推出雲端運算相關之服務,服務的類型可分為許多種,其中較為普遍的分類包括了 SaaS、PaaS、IaaS 三種,例如:Google 提供的「Google Docs」服務,讓使用者能夠透 過網路,存取並編輯各種文件,無需花時間於電腦上安裝並定期更新軟體,或是花大 錢購買軟體授權,是目前一般使用者較為常用的一種「軟體即服務」(SaaS)的代表;
以網路書店及拍賣聞名的Amazon,近年來也藉由雲端運算的各項技術,提供使用者 CPU 運算資源及儲存空間,亦即所謂的「基礎設施即服務」(IaaS),該服務包含了虛 擬化且標準化的伺服器、網路設備、記憶體、儲存設備、CPU、資料中心等,讓企業 用戶以購買現成服務的方式取代傳統冗長的購買、安裝、測試、上線的過程,並能夠 依據自己的使用量來付費,此外,使用者無須為了符合尖峰時段的需求,花費大量金 錢購置平時很有可能閒置的硬體資源,不但可以降低採購成本,亦可減少在維護上所 耗費的心力,達到節省IT 總持有成本的目的。由上述的兩個例子可知,對於使用者而 言,雲端運算的概念即為透過網際網路,快速而簡便地取得恰好符合需求的IT 資源與 服務,並採具有彈性的收費方式來計價。
本研究所要探討的重點鎖定在雲端運算中的「基礎設施即服務」(IaaS)上,由於 上述的諸多好處,使得許多企業趨之若鶩,政府機關也積極評估考慮,紛紛探索是否 能以IaaS 的形式取代現有的資訊基礎設施架構。而業界按照提供者與使用者的所屬關 係,將雲端運算分為三種模式,首先為「公有雲」,使用者所需的服務由獨立的第三方 雲端供應商提供,並與其他若干企業用戶共同使用雲端運算環境,此模式能夠享有雲 端運算中最完整的好處,包括了靈活度、高效能、節省成本等,但相對地也必須面對 資料安全的風險、服務是否穩定以及是否具備令人滿意的服務水準等問題;若企業對 於資料安全性、服務可靠性及IT 可監控性的要求較高,則可考慮獨力建構僅供企業內 部成員使用的「私有雲」,雖能有效避免使用公有雲所帶來的負面影響,但也相對地喪 失了雲端運算所帶來的某些優勢,例如:無法有效降低IT 的總持有成本與所需之維護 心力;至於所謂的「混合雲」則為前述二者兼而有之的型態。
