Welcome to Orleans, a virtual actor framework from Microsoft that allows
a single developer to create immensely scalable, available applications
while maintaining a high throughput. This guide is designed to give you
a foundational understanding of Orleans, an overview of its
implementations, and plenty of hands-on coding experience. Side-by-side
monolithic and microservice patterns alongside Orleans' framework
features are also discussed, to help readers without an actor model
background understand how they can enhance applications.
Author Nelson's approach is to introduce patterns as needed for business
requirements, including monolithic microservices and to convert
monolithic to microservices, in order to keep a microservice from
growing into a monolithic application. Orleans is a good choice for
either of these scenarios as the next step to build your backend
services and reduce unnecessary orchestration, overhead, and tooling.
The Orleans framework was designed to handle tedious overhead, allowing
the developer to focus on the solution. You will learn how Orleans can
support billions of virtually parallel transactions while sustaining low
latency and high availability. In addition, you will glimpse under the
hood at Orleans to discover its useful attributes. All key learning
points include hands-on coding examples to reinforce understanding.
This book goes beyond what Orleans is to explain where it fits within
the realm of development. You will gain an in-depth understanding to
build a foundation for future growth.
What You Will Learn
- Understand how Orleans can benefit your monolithic and/or microservice
applications
- Gain a brief overview of actor models and how they relate to Orleans
- Observe the design patterns and how Orleans can simplify or reduce
tooling requirements
- Know the pros and cons of microservices and Orleans to determine the
best course of action based on the needs of an application
- Discover Orleans' design patterns and practices, including life cycle,
messaging guarantees, cluster management, streams, load balancing, and
more
- Build your first Orleans' application; build base knowledge of
application structure, unit testing, dashboard, scheduled events
