In the video titled "Scaling a Monolith Isn't Scaling Microservices," speaker Kerstin Puschke discusses the differences between background jobs and message-oriented middleware in the context of workload distribution across different architectures, particularly focusing on monolithic and distributed systems.

The key points discussed in the presentation include:  
- **Background Jobs**: Puschke explains the concept of background jobs in Ruby applications, highlighting their advantages in decoupling user-facing requests from backend tasks, which is crucial for enhancing response times and user experience.  
- **Task Queue Systems**: She details how popular background job backends like Rescue and Sidekiq enable asynchronous operations, illustrating how they can be beneficial in high-demand scenarios like e-commerce applications.  
- **Message-Oriented Middleware**: Puschke contrasts background jobs with message-oriented middleware, such as RabbitMQ, which helps facilitate communication between different services in distributed architectures. This middleware allows for enhanced scalability and decoupling of services compared to traditional background jobs.  
- **Event Streams and Logs**: The speaker also talks about event logs, exemplified by Kafka, which maintains sequences of events in a stateless manner, allowing greater flexibility in data handling and consumer roles.  
- **Challenges with Asynchrony**: The challenges around asynchrony, such as ensuring message delivery and maintaining order in job processing, are addressed, emphasizing the importance of idempotent operations to avoid issues like double charges in financial transactions.  
- **Real-World Applications**: Puschke provides insights into how Shopify successfully employs these techniques, managing vast numbers of background jobs, particularly during peak sales periods like Black Friday, showcasing a Kafka-powered dashboard for real-time visuals of sales data.  
In conclusion, Puschke urges developers to carefully choose between these architectural patterns based on their application's needs, stressing that while background jobs are ideal for monolithic systems, message-oriented middleware and event logs offer significant advantages in distributed environments.  
This video serves as an insightful guide for developers and engineers looking to optimize their systems and understand the implications of different architectural decisions in software scalability.
