A solutions architect is designing the cloud architecture for a company that needs to host hundreds of machine learning models for its users.During startup, the models need to load up to 10 GB of data from Amazon S3 into memory, but they do not need disk access.Most of the models are used sporadically, but the users expect all of them to be highly available and accessible with low latency.Which solution meets the requirements and is MOST cost-effective?Read More →
A company is building a machine learning (ML) model to classify images of plants.An ML specialist has trained the model using the Amazon SageMaker built-in Image Classification algorithm.The model is hosted using a SageMaker endpoint on an ml.m5.xlarge instance for real-time inference.When used by researchers in the field, the inference has greater latency than is acceptable.The latency gets worse when multiple researchers perform inference at the same time on their devices.Using Amazon CloudWatch metrics, the ML specialist notices that the ModelLatency metric shows a high value and is responsible for most of the response latency.The ML specialist needs to fix the performance issue so that researchers can experience less latency when performing inference from their devices.Which action should the ML specialist take to meet this requirement?Read More →
