APPENDIX A

Pattern Analysis Summary

Figure A-1 summarizes the pattern-analysis scoring for each of the architecture patterns described in this report. This summary will help you determine which pattern might be best for your situation. For example, if your primary architectural concern is scalability, you can look across this chart and see that the event-driven pattern, microservices pattern, and space-based pattern are probably good architecture pattern choices. Similarly, if you choose the layered architecture pattern for your application, you can refer to the chart to see that deployment, performance, and scalability might be risk areas in your architecture. 45

模式分析总结

图A-1 总结了在这个报告中，对于架构模式的每部分进行的模式分析所产生的影响。这个总结帮助你确定哪些模式可能是最适合你的情况。例如,如果你的架构模式重点是可伸缩性，你可以在这个图表看看事件驱动模式,microservices模式,和基于空间模式，这些对于你来说可能是很好的架构模式的选择。同样的,如果你的程序注重的是分层架构模式,你可以参考图看到部署、性能和可伸缩性的在你的架构中所存在的风险。

While this chart will help guide you in choosing the right pattern, there is much more to consider when choosing an architecture pattern. You must analyze all aspects of your environment, including infrastructure support, developer skill set, project budget, project deadlines, and application size (to name a few). Choosing the right architecture pattern is critical, because once an architecture is in place, it is very hard (and expensive) to change

同时这个图表将指导你选择正确的模式, 因为在选择一种架构模式的时候，有更多的需要考虑。 你必须分析你的环境的各个方面,包括 基础设施的支持,开发人员技能,项目预算,项目 最后期限,和应用程序大小(等等)。选择正确的 架构模式是至关重要的,因为一旦一个架构 被确定了就很难改变。
