Q2. What are the future works mentioned in the paper "Developing a government enterprise architecture framework to support the requirements of big and open linked data with the use of cloud computing" ?
Future research will be focused on the detailed requirements, especially in the context of the integration into the existing IS/ICT infrastructure in the organization.
Q3. What are the support components for both consumer and provider?
The support components for both consumer and provider are: security and privacy; architecture management and control; operations support in architecture; architecture performance and elasticity; and coordination and cooperation of components.
Q4. What types of data storage are needed to adapt to large amounts of data?
A data storage requires new types of distributed file systems, i.e. NoSQL, NewSQL, Massively Parallel Processing (MPP) or in-memory database architecture to adapt to large amounts of data and changing structures.
Q5. What are the other architectural components for a cloud provider?
The other identified architectural components for a cloud provider are distinguished into six layers:cloud services delivery models; access / service delivery at different levels and access infrastructure; service search and management; service orchestration and cloud management; resources abstraction (virtualization); physical resources for cloud services and equipment.
Q6. What are the methods of analysis, synthesis, abstraction, decomposition, and modelling used?
For artifact design and development, the methods of analysis, synthesis, abstraction, comparison, decomposition, and modelling are used.
Q7. What is the key view of the framework?
As a part of the process view the framework proposes to focus on the support of related processes which may be modelled in a hierarchical manner.
Q8. What is the definition of a lifecycle of big data?
a lifecycle of big data can be divided in four phases (Chen et al., 2014): data generation, data acquisition, data storage, and data analysis.
Q9. What are the limitations to validity of the study’s results and architectural claims in other countries or?
The limitations to validity of the study’s results and architectural claims in other countries or organizations are related to different types of administrative structures and responsibility, coverage, and liability between them in the public sectors worldwide.
Q10. How many respondents see the need to integrate cloud services into their respective enterprise architecture?
A survey conducted by Sutherland and Chetty (2014) showed that up to 75% of the respondents see the need to incorporate cloud services into their respective enterprise architecture.
Q11. What is the classification of data stores?
Data stores classification is based on the National Institute of Standards and Technology (NIST) Big Data Interoperability Framework (NIST, 2015).
Q12. What is the problem of having enough computing power to process these data?
The combination of size, multiple sources, and unstructured data then presents the problem of having sufficient computing power to process these data.
Q13. What are the key steps of the new methodology?
The key steps of the new methodology are defined as follows: the first step is focused on the global and information strategy (a change from current to target state), in this case, it is about the solution, which should be cost effective so asto ensure low cost investments in hardware, software, and data maintenance, it is followed by the analysis of current trends in ICT, analysis of the existing IS/ICT infrastructure in the organization, etc., the responsible stakeholder is system orchestrator, the output of this step is the SWOT analysis; the second step is the initial feasibility study phase where it is required to select related stakeholders and create a team, which will define and approve the requirements speci-fication, the output is report with an overview of the basic requirements (boundaries), including various alternatives, and a roadmap containing a list of risks, budget and schedule in the context of economy and costs; the third step is the global analysis phase, i.e., proposal of the architecture at the conceptual level, which can be described by the related components for each of the partialviews on architecture, the output is a revised list of requirements, global and partial architectures, strategy for ensuring the security and quality attributes, etc., more can be found in the content dimension of the MMDIS; it is followed by the detailed requirements specification, while this step is defined by the techniques and guidelines for models suggested by the TOGAF, i.e., ADM/MDA,the output of this step are the concrete models at required levels of views ready to implement, respectively to validate and verify them; the following steps then are: system implementation, system installation, system administration and maintenance, and system elimination.
Q14. How long did the expert work at the Regional authority of Pardubice?
The expert from the practice worked as the head of the Department of information technology of Regional authority of Pardubice region with 15 years of practice at this position, namely with development and implementation of IS in the public sector.
Q15. What is the definition of a process architecture?
A process architecture is the means by which the organization establishes a set of rules, principles, guidelines and models for the implementation of the process management across the organization.
Q16. What are the main reasons for the inclusion of cloud services in the enterprise architecture?
In addition, many cloud vendors such as Amazon, Google, IBM, Oracle and Microsoft also proposed their own architectural styles to combine enterprise architectures and the power of cloud computing powers (Mahmood, 2011; Sharma, 2016; Shroff, 2010).
Q17. What are the related components for the cloud provider?
As an example of related sub-components for the cloud provider on the second view level, the service orchestration and cloud management component is chosen.
Q18. What were the key architectural components identified?
the decomposition of published architecture and reference frameworks was done and the key architectural components were identified.
