Introduction Cloud Computing is increasingly used as the platform for ICT infrastructure provisioning, appli

14、cation/systems development and end user support of a wide range of core services and applications for businesses and organizations. Cloud Computing is drastically changing the way ICT is delivered and used. However, many challenges remain to be tackled. Concerns such as security, vendor lock-in, int

15、eroperability and accessibility, service level agreements more oriented towards users are examples of issues that need to be addressed. The survey discussed in the present report aims at collecting information on the respondents awareness of those concerns. Standards and certification programs play

16、an important role in terms of increasing the market confidence in Cloud Computing. The promotion of Cloud Computing standards and certification schemes that address current concerns is necessary in order to ensure that both customers/users as well as providers will regard Cloud Computing with the sa

17、me level of reliability, trust and maturity as traditional ICT. In February 2015, the Cloud Standards Coordination Phase 2 (CSC-2) was launched by ETSI to address issues left open after the initial Cloud Standards Coordination work was completed at the end of 2013. Cloud Standards Coordination Phase

18、 2 is investigating some specific aspects of the Cloud Computing standardization landscape, in particular from the point of view of the Cloud Computing users (e.g. SMEs, Administrations). It will also generate a new snapshot regarding the state of standards and investigate the interaction and relati

19、on between standardization and open source based software and solutions. The present document presents the results of the web survey conducted in April - September 2015.

25、 “Budgeting for the SaaS Security Gap“, January 28, 2015. i.3 Skyhigh: “Cloud Adoption the organization making the leap to the Cloud need to be prepared. Nearly half of respondents claim that efforts related to data categorization (43 %) and data classification (35 %) are on-going in their organizat

26、ions. Data security awareness and level control is seen as a highly important aspect that needs to be tackled by a majority of the respondents. Regarding software licenses, 37 % of the respondents indicate that negotiations are on-going with the software vendors providing Cloud Computing software it

27、 is not entirely clear if answers in this category indicate that actions are not needed or if necessary measures have already been taken). Cloud Deployment Models and Cloud Service Categories: Private Cloud deployment models clearly dominate followed by Hybrid Cloud and Public Cloud deployments. Con

28、cerning Cloud Service Categories, high-availability is seen as the top usage area for IaaS while software development is also seen as the top capability for PaaS. Concerning SaaS, the general data storage type of application is ranked high while specialized applications supporting for example supply

29、 chain services, HR, ERP or CRM are less frequently mentioned. Notably, 54 % of the respondents indicate an interest in emerging Cloud Service Categories such as CaaS, NaaS, DsaaS and CompaaS. Cloud computing and standards: Security, privacy and integrity, performance and portability across vendor s

30、olutions are ranked high regarding the impact that standards have on the concerns of organizations. In terms of how standards are considered in the organizations of the respondents, 38 % indicate that standards are used while 27 % that they are considered. This shows a promising insight into the val

31、ue and importance of standards. In line with the responses regarding impact of standards, interoperability, security, service level agreements, portability and APIs are mentioned as top priorities. The feedback also indicates that recently published standards are now becoming known by a small number

32、 of respondents. Examples of standards used or considered are ISO/IEC 17788 i.5 - Recommendation ITU-T Y.3500 i.1 - ISO/IEC 17789 i.6 and Recommendation ITU-T Y.3502 i.7. However, the number of answers is too insignificant to claim that the Cloud Computing specific standards are now part of the Clou

33、d strategy for most organizations. Cloud computing certifications: Almost 75 % of the respondents see certification schemes as a positive way of increasing confidence in Cloud Service Providers. Amongst the cross-cutting aspects, the two (security, privacy and integrity) seen as both most critical f

34、or the maturity of cloud computing Q11 and as aspects where standards are expected to have highest impact Q34, certifications for these aspects are actually ranked as close to the least important Q48. The most important issues for certification are: data storage location (one aspect of privacy), clo

35、ud datacentre infrastructure, cloud provisioning process and interoperability/reversibility. A more detailed analysis is found in clause A.11 of the present document. A majority of the respondents are unaware of the Cloud Certification Schemes List (CCSL) defined by ENISA while in this list, the wel

36、l-known ISO/IEC 27001 i.8 comes first as a scheme for Cloud certification. A majority of the Cloud Service Customers indicate that they plan to include one of these certification schemes in their Cloud Computing procuring processes. A majority of Cloud Service Providers also plans to certify their C

37、loud Service offerings. 6.2 Trends and patterns Based on the responses received, it is possible to make some tentative and high-level analysis. From this analysis, some patterns emerge that will have to be clarified and confirmed by a final analysis made at the conclusion of the survey. The trends t

38、hat are assessed as the most significant are presented below. Security, Integrity and Data Privacy: These topics are seen as major concerns for cloud maturity and for standards impact, although not for certification. This is not a new finding, but the fact that it is still very much present is a cle

39、ar indication on the perceived challenge ahead for security standards and Cloud certification in particular. Interoperability and Portability: These areas are ranked high. Concern in this area is most likely linked to the issue of vendor lock-in, the unclear capabilities of individual cloud service

40、offerings ability to move data from one service to another and the lack of portability standards for cross-Cloud scenarios in general. ETSI ETSI SR 003 381 V2.1.1 (2016-02) 13 Moving to the Cloud: There is a high perception from the respondents that the transition to Cloud Computing should be carefu

41、lly planned and organized, in particular in areas pertinent to data (classification, storage, etc.), processes and security. Standards: In general, the role of standards is seen as important and there is a growing level of awareness, even in terms of knowledge of the existing set of standards. It is

42、 to be noted that, in this perspective, the benefit from standards related to Cloud Computing is seen as more critical than Open Source: this finding is however subject to further analysis. This topic is further explored in ETSI SR 003 382 i.12. Certification: A very large majority (over 80 %) of th

43、e respondents confirm the role of certification as a very useful way to improve confidence in Cloud Computing. However the selection of Cloud Certification schemes is complex: the Cloud Certification Scheme List (CCSL) is an attempt to make a selection of such schemes but the survey shows that only

44、31 % of respondents are aware of this list. This is clearly showing a need for increasing the awareness of the Cloud Computing community on CCSL and all the means to have access to a pre-analysed and recommended list of certification schemes. 6.3 Detailed findings 6.3.1 Adoption of Cloud Computing T

45、he web survey clearly indicates which Cloud Computing Service Categories (SaaS, PaaS, IaaS, etc.) and Cloud Computing Deployment Models (Public, Community, Private or Hybrid) are most common in terms of usage; IaaS and provisioning infrastructure as well as general data storage constitute the most p

46、opular Service Categories and usage areas where the Private Cloud Deployment Models come out first as the Deployment Model. The adoption of Cloud Computing and Cloud Computing based services continues to grow across Europe. Studies also show that the use of Cloud Computing services is steadily growi

47、ng worldwide. In a recent study published by Skyhigh “Cloud Adoption the conclusion might be that there is simply not yet sufficient confidence in Cloud Computing for the users to provision and process sensitive data in the cloud computing space. It is recommended to further investigate the reasons

48、(such as security concerns, regulatory, etc.) for the slow adoption of SaaS for sensitive data needs. There are different legal barriers across Europe and no up-to-date European Data Protection Regulation yet. Among the low number of respondents, ISO/IEC 27001 i.8 is the standard most known and used

49、. “Security“ is a complex, slightly ambiguous and imprecise concept. It can be and probably is interpreted in many different ways. Security can for instance map to and concern one or more of the following areas: - Data protection (and information classification, data encryption, etc.) - Data access - Identity management - Authorization - Authentication - Data privacy - Data integrity - Accessibility - Operations and probably some additional domains/areas. It is likely that “Security“ and “Privacy and integrity“ are in fact grouped together
