The architecture design specifies the overall architecture and the placement of software and hardware that will be used. Architecture design is a very complex process that is often left to experienced architecture designers and consultants. The first step is to refine the () into more detailed requirements that are then employed to help select the architecture to be used and the software components to be placed on each device. In a (), one also has to decide whether to use a two-tier, three-tier, or n-tier architecture. Then the requirements and the architecturedesign are used to develop the hardware and software specification. There are four primary types of nonfunctional requirements that can be important in designing the architecture. () specify the operating environment(s) in which the system must perform and how those may change over time. ( 请作答此空) focus on the nonfunctional requirements issues such as response time, capacity, and reliability. () are the abilities to protect the information system from disruption and data loss, whether caused by an intentional act. Cultural and political requirements are specific to the countries in which the system will be used.
A. Environment requirements
环境要求
B. Maintainability requirements
可维修性要求
C. Performance requirements
性能要求
D. Virus control requirements
病毒控制要求

多选题Identify three reasons that explain why assigning more than one managed serve achieve better performance than running one managed server with more resources?（）AThread management inside the JVM process might be less effective than context switching between processes on the OS level. It is better to combine both these technologies to achieve full saturation of resources.BCurrent CPUs are multicore units. So starting managed servers in the amount of physical cores and pinning them 1:1 to cores will always get the best performance.CBy a combination of prioritization of processes on the OS level and Work Manager in WLS, one could tune the whole environment more precisely.DAssigning more than one managed server to hardware will never bring better performance.EMore instances means more connections to databases, so one could serve more concurrent calls on the database level. This is primarily why this approach will give better performance numbers.FDepending on the profile of the application, having more JVMs with smaller heaps will lead to more predictable response times than fewer JVMs with a large heap.
