領域驅動設計台灣2024年會 – DDDesign Taiwan Conference 2024

現代應用系統的開發，不但得擔負過往遺留系統的包袱，還要增進現行業務流程的價值與效用，以及可持續的維運，更期望顧及可應對未來商業演變的延展與彈性。

今年年會的主題之一：「遺留工作負載（legacy workloads）」，指的是在企業中已經運行了很長時間，但仍然需要維持的應用程式與系統。這些工作負載當初所使用的技術，運行所在的硬體與平台，現今看來可能已過時與老舊，整體運行甚至已顯疲態（過慢或無效率），基於商業流程的必需性，卻又無法更新或廢除。這樣的系統通常會出現穩定性、相依性與複雜性的狀況，並且累積技術債卻又缺乏技術支援。

例如Store Procedure過往曾經一度是在開發應用系統時，為了提高效率與時間，常用的應用設計。到現今的技術平台與架構環境，這樣的設計逐漸出現維護困難、資料相依性過高與對商業規則延展性低等問題。若要對這些狀況改善，關聯的不只是程式的修改或重構，更多是系統流程與架構的變更與整合。

而遺留工作負載（legacy workloads），更是有如家族代代相傳的「遺產」，該如何處理這遺產，跟企業的商業發展息息相關，考驗著企業資訊系統的發展與管理：

– 🔧 是否該現代化，該如何現代化：這必須思考平衡保持遺留系統的穩定性與更新技術的需求。透過重新設計改動應用系統、遷移到雲端平台或採用容器化技術，都是可以實現現代化的方式。

– 🔧 現代化的風險管理：改善與重構遺留系統的現代化過程中，需要確保不會影響商業營運的連續性和數據的完整性。

– 🔧 成本與效益的評估：現代化遺留系統的成本，與現代化後對商業價值改善的效益，需要相應的成本效益分析，來確定最佳的升級方式。

– 🔧 技術的汰換與培養：維護遺留系統所需的技術專長，不論在人員或資源上，可能會隨著時間逐漸稀缺。因此需要思考是否進行培訓或尋求外部支持。

– 🔧 管理控制技術債：遺留系統常會伴隨累積技術債務，必須釐清緣由以制定策略，來做有效管理和降低技術債，確保兼顧系統的靈活性和維護性。

總而言之，為了企業的長期發展和技術創新，必須有效的管理與現代化遺留工作負載，值得每個從事系統開發與維運的人花時間去了解與交流學習。

你對遺留工作負載有什麼看法與見解呢？或是想知道什麼呢？請手刀報名今年的活動盛事吧！

Developing modern application systems requires not only dealing with legacy systems but also enhancing current business processes for sustainability, maintaining operational efficiency, and ensuring flexibility to adapt to future business changes.

One of this year’s conference themes is “Legacy Workloads,” referring to applications and systems that have been in operation for a long time but still need maintenance. These workloads often use outdated technologies, hardware, and platforms that may now seem obsolete and inefficient. However, due to business process requirements, they cannot be easily updated or discarded. These systems often face issues of stability, dependency, and complexity, accumulating technical debt with insufficient technical support.

For example, Stored Procedures were once widely used to improve efficiency and development time. However, in today’s technological environment, such designs often face maintenance difficulties, high data dependency, and low flexibility in adapting to business rules. Improving these issues requires not only code modification or refactoring but also changes and integration in system processes and architecture.

Legacy workloads are like inherited family “assets.” How to handle these assets is crucial to a company’s business development, testing the development and management of enterprise information systems:

• 🔧 Modernization and How to Modernize: This involves balancing the stability of legacy systems with the need for updated technologies. Approaches like redesigning applications, migrating to cloud platforms, or adopting containerization can achieve modernization.
• 🔧 Risk Management in Modernization: Ensuring that the modernization process does not disrupt business continuity and data integrity.
• 🔧 Cost-Benefit Analysis: Evaluating the costs of modernizing legacy systems against the benefits of improved business value to determine the best upgrade approach.
• 🔧 Technical Skill Replacement and Training: The expertise required to maintain legacy systems may become scarce over time, necessitating training or seeking external support.
• 🔧 Managing Technical Debt: Understanding the causes of accumulated technical debt in legacy systems and devising strategies to manage and reduce it effectively, ensuring system flexibility and maintainability.

In summary, effective management and modernization of legacy workloads are essential for long-term business development and technological innovation. It is worth every system developer and maintainer’s time to understand, share, and learn about these issues.
