部分 1 的 3: 三種方式的企業IT來提高業務應用交付的在混合IT的可靠性
企業CTO們希望能加速業務應用現代化和雲部署. The journey begins with a review of each on premises legacy app, in order to assess whether it will be easy or problematic to move to cloud, and to decide which parts should be moved first. The app owner asks IT some ‘simple’ questions: Where is my app? What infrastructure does my app depend on? Can you give me a ‘map of my app’? In many enterprises today, it’s still not easy for IT to provide the app dependency visibility needed.
IBM業務合作夥伴有機會幫助客戶一步之基本發現, 提高自動化程度，並映射應用程序依賴關係. In this three part blog series, we will discuss the following ways to improve reliability:
- Plan app modernization to minimize business user impact based on understanding legacy app dependencies on Hybrid IT
- Shorten the time to isolate the origin of app user issues (Check back 11/14)
- Manage Hybrid IT infrastructure change to avoid business app user impact (Check back 11/27)
Before tackling the job of modernizing applications, Dev and Ops teams need to understand the application inventory from a modernization perspective and classify the application portfolio. As legacy apps and workloads are evaluated for migration to cloud, it becomes clear that not all apps will be modernized, nor all components. Enterprises will want to modernize the interactive parts facing the end users first. 然而, the decision to move a specific workload to the cloud is not a trivial one.
App owners need a deeper understanding of the app delivery environment. To identify workloads that might be re-located to cloud, you need to understand all the physical, logical, and operational relationships and dependencies between resources. 出於這樣的原因, app owners are looking to IT for more visibility into the end-to-end hybrid infrastructure that their apps depend on. They need a deep understanding of the app’s dependency on a complex delivery infrastructure comprising middleware, specialized servers and sub-components, 雲計算, virtualized and physical environments, and resources provided by dedicated storage and network infrastructure.
Dependencies between components also need to be understood. 舉個例子, duplicated system resources may be used for backup and disaster recovery. Specialized resources may be used for performance optimization (例如, clustering, load balancing). The app may also have dependencies on additional centrally controlled services like authorization and security.
IT needs to provide the app owners with topology map views showing the app dependencies on the underlying Hybrid IT. This app dependency data is critical input from the initial analysis phase to the final phase of validating the application after components are moved to the cloud.
讓客戶知道，增值，他們可以從IBM的Tivoli應用依賴性發現管理器解鎖 (TADDM), e.g. 利用其投資的BigFix自動防火牆的後面發現區, 並實現應用程序依賴映射，以增加整個企業的知名度和理解. 讓客戶知道，他們可以與IBM新的靈活的服務管理能力，擴展他們發現解決方案.
