Priority Tier 3 Domain 3: Design High-Performing Architectures Domain 4: Design Cost-Optimized Architectures

This section covers considerations for designing scalable and cost-effective solutions for dynamic, stateless batch processing jobs that can tolerate interruptions, recommending EC2 Spot Instances as a suitable compute option.

Learning Objectives

Understand the characteristics of a dynamic, stateless, fault-tolerant batch processing job.
Identify AWS EC2 Spot Instances as a cost-effective solution for such batch processing workloads.
Recognize the limitations of AWS Lambda for long-duration batch processing tasks.

Batch Processing Workloads

Understanding the nature of batch processing jobs and recommended AWS compute solutions for them.

A batch processing job that is highly dynamic, stateless, and can tolerate interruptions, making it resilient to potential restarts or disruptions.

EC2 Spot Instances are an ideal solution for stateless, fault-tolerant, and flexible workloads such as dynamic batch processing jobs.

Technical Specs: Offers up to 90% cost savings compared to On-Demand instances.

AWS Lambda is designed for short-duration tasks and is therefore unsuitable for batch processing jobs that require longer execution times.

Technical Specs: Unsuitable for jobs > 60 minutes.

Exam Tips

When designing solutions for dynamic, stateless batch processing jobs that can tolerate interruptions, EC2 Spot Instances are a highly cost-effective choice (up to 90% savings).
Remember that AWS Lambda is designed for short-duration tasks and is unsuitable for batch processing jobs that exceed 60 minutes.

Glossary

Stateless Batch Processing Job

A batch processing job that can be restarted without negative impact.

Key Takeaways

EC2 Spot Instances are recommended for highly dynamic, stateless, and fault-tolerant batch processing jobs due to significant cost savings (up to 90% off On-Demand rates). (source page 5)
AWS Lambda is not suitable for batch jobs exceeding 60 minutes, as it is designed for short-duration tasks. (source page 5)
Understanding Batch's key features and integration patterns is essential for SAA-C03 exam success.
