Hello Kumar Mahadevan,
Thanks for the reply.
Here are the key aspects to consider:
Cost Savings:
Spot Instances allow you to bid for unused EC2 capacity at a reduced cost compared to On-Demand pricing.
Given that the company wants to reduce costs, leveraging Spot Instances can be a strategic choice.
Keywords to Look For:
Reduce Costs: Indicates that cost-saving measures like Spot Instances should be considered.
Auto Scaling: Spot Instances can be integrated with Auto Scaling groups, making it a good fit for dynamically scaling workloads.
Non-Critical, Interruptible Workloads: Spot Instances are ideal for workloads that can tolerate interruptions, such as batch processing or background tasks. Since videos are uploaded, placed in an Amazon SQS queue, and then processed, there’s no immediate requirement for real-time processing.
Even if a Spot Instance is interrupted, another instance from the queue can retry the processing task.
Use Case Context:
Processing SQS Queue: Since SQS processing tasks are not critical and can tolerate interruptions, Spot Instances are a suitable choice. Even if a Spot Instance is terminated, another instance can reprocess the message.
As mentioned in the explanation, the videos are processed and stored in the EBS volumes, suggesting that the service is dynamic in nature. Amazon S3’s static website hosting does not provide server-side processing, which is necessary for dynamic websites.
By identifying these keywords and understanding the requirements, you can determine the suitability of Spot Instances in the provided scenario.
I hope this helps! If you have any more questions or need further assistance, feel free to ask.
Best regards,
