توضیحاتی در مورد کتاب ایجاد خدمات خرد رویداد محور: استفاده از داده های سازمانی در مقیاس

امروزه سازمان‌ها اغلب برای متعادل کردن نیازهای تجاری با حجم روزافزون داده‌ها تلاش می‌کنند. علاوه بر این، تقاضا برای استفاده از داده‌های در مقیاس بزرگ و بلادرنگ در بین رقابتی‌ترین صنایع دیجیتال به سرعت در حال رشد است. معماری سیستم های متعارف ممکن است در حد کار نباشد. با این راهنمای عملی، می‌آموزید که چگونه با استفاده از اصول ریزسرویس‌های رویداد محور، از مصرف داده در مقیاس بزرگ در واحدهای تجاری سازمان خود استفاده کنید. نویسنده Adam Bellemare شما را در فرآیند ایجاد یک سازمان مبتنی بر میکروسرویس رویداد محور راهنمایی می کند. نحوه تولید، دسترسی و انتشار داده ها در سراسر سازمان خود را مجدداً بررسی خواهید کرد. الگوهای قدرتمند و در عین حال ساده را برای باز کردن قفل ارزش این داده ها بیاموزید. طراحی رویداد محور و اصول معماری را در سیستم های خود بگنجانید. و به طور کامل تجدید نظر کنید که چگونه سازمان شما با باز کردن قفل دسترسی تقریباً واقعی به داده ها در مقیاس، ارزش ارائه می دهد. یاد خواهید گرفت: • چگونه می توان از معماری های رویداد محور برای ارائه ارزش تجاری استثنایی استفاده کرد • نقش میکروسرویس ها در حمایت از طرح های رویداد محور • الگوهای معماری برای اطمینان از موفقیت در درون و بین تیم های سازمان شما • الگوهای کاربردی برای توسعه میکروسرویس های قدرتمند رویداد محور • اجزاء و ابزار مورد نیاز برای از بین بردن اکوسیستم میکروسرویس شما


توضیحاتی درمورد کتاب به خارجی

Organizations today often struggle to balance business requirements with ever-increasing volumes of data. Additionally, the demand for leveraging large-scale, real-time data is growing rapidly among the most competitive digital industries. Conventional system architectures may not be up to the task. With this practical guide, you’ll learn how to leverage large-scale data usage across the business units in your organization using the principles of event-driven microservices. Author Adam Bellemare takes you through the process of building an event-driven microservice-powered organization. You’ll reconsider how data is produced, accessed, and propagated across your organization. Learn powerful yet simple patterns for unlocking the value of this data. Incorporate event-driven design and architectural principles into your own systems. And completely rethink how your organization delivers value by unlocking near-real-time access to data at scale. You’ll learn: • How to leverage event-driven architectures to deliver exceptional business value • The role of microservices in supporting event-driven designs • Architectural patterns to ensure success both within and between teams in your organization • Application patterns for developing powerful event-driven microservices • Components and tooling required to get your microservice ecosystem off the ground
