توجه داشته باشید کتاب اتوماسیون فرآیند عملی: ارکستراسیون و ادغام در میکروسرویس ها و معماری های بومی ابری نسخه زبان اصلی می باشد و کتاب ترجمه شده به فارسی نمی باشد. وبسایت اینترنشنال لایبرری ارائه دهنده کتاب های زبان اصلی می باشد و هیچ گونه کتاب ترجمه شده یا نوشته شده به فارسی را ارائه نمی دهد.
در معماریهای فناوری اطلاعات امروزی، میکروسرویسها و توابع بدون سرور نقش مهمی را در اتوماسیون فرآیند ایفا میکنند. اما چگونه میتوانید راهحلهای تجاری معنادار، جامع و مرتبط ایجاد کنید، زمانی که اجزای جداگانه با طراحی جدا و مستقل هستند؟ این کتاب با هدف توسعهدهندگان و معماران، چارچوبی را از طریق مثالها، توصیههای عملی و موارد استفاده ارائه میدهد تا به شما در طراحی و خودکارسازی فرآیندهای پیچیده کمک کند. از آنجایی که سیستمها توزیعشدهتر، ناهمزمانتر و واکنشپذیرتر هستند، اتوماسیون فرآیند برای مقابله با فعل و انفعالات طولانیمدت نیاز به مدیریت حالت دارد. نویسنده Bernd Ruecker نشان می دهد که چگونه می توان از فناوری اتوماسیون فرآیند مانند موتورهای گردش کار برای هماهنگ کردن نرم افزارها، انسان ها، تصمیمات یا ربات ها استفاده کرد. • بیاموزید که چگونه اتوماسیون فرآیند مدرن با مدیریت فرآیند کسب و کار، معماری سرویس گرا، پردازش دسته ای، جریان رویداد و راه حل های خط لوله داده مقایسه می شود. • نحوه استفاده از موتورهای گردش کار و مدل های فرآیند اجرایی با BPMN را بدانید • تفاوت بین ارکستراسیون و رقص و نحوه تعادل هر دو را درک کنید
In today's IT architectures, microservices and serverless functions play increasingly important roles in process automation. But how do you create meaningful, comprehensive, and connected business solutions when the individual components are decoupled and independent by design? Targeted at developers and architects, this book presents a framework through examples, practical advice, and use cases to help you design and automate complex processes. As systems are more distributed, asynchronous, and reactive, process automation requires state handling to deal with long-running interactions. Author Bernd Ruecker demonstrates how to leverage process automation technology like workflow engines to orchestrate software, humans, decisions, or bots. • Learn how modern process automation compares to business process management, service-oriented architecture, batch processing, event streaming, and data pipeline solutions • Understand how to use workflow engines and executable process models with BPMN • Understand the difference between orchestration and choreography and how to balance both
