You can use SageMaker to deploy a model to get predictions in several ways:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Real-time<\/li>\n\n\n\n<li>Batch transform<\/li>\n\n\n\n<li>Asynchronous<\/li>\n\n\n\n<li>Serverless<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">ML Security and Compliance<\/h3>\n\n\n\n<p>Security and compliance best practices ensure your ML environment is secure from threats and resulting financial losses, and compliant with fraud prevention regulations. AWS offers various services to protect ML environments:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>AWS Identity Access Management (AWS IAM): control access to ML resources using fine-grained access control, least privilege principle, role-based access control, and temporary security credentials.<\/li>\n\n\n\n<li>AWS Key Management Service (AWS KMS): manage encryption keys to protect sensitive data in ML workflows.<\/li>\n\n\n\n<li>SageMaker security features:&nbsp; safeguard your ML environment from external threats by running training jobs and deploying models in an isolated network environment (Amazon Virtual Private Cloud \u2013 VPC). Integrate your model with CloudTrail and CloudWatch to detect unusual activities.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Monitoring and Maintenance<\/h3>\n\n\n\n<p>After a model is deployed, it must be monitored and maintained for smooth functioning. AWS offers several services for monitoring and maintenance:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Amazon SageMaker Debugger: get insights during training to identify and resolve issues.<\/li>\n\n\n\n<li>&nbsp;Amazon CloudWatch: monitor models and receive logs metrics from models and infrastructure, showing performance and operational health.<\/li>\n\n\n\n<li>Amazon SageMaker Model Monitor: check monitoring reports on deployed models for data drift and performance degradation, with features to automatically retrain models if necessary.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">AWS AI Services<\/h3>\n\n\n\n<p>Amazon AI services add extra value to AWS ML deployments, providing advanced functionalities and ease of integration that complement the core ML capabilities. These AI services enhance the overall experience and effectiveness of deploying machine learning solutions on AWS.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Amazon Comprehend, analyzes and extracts insights from text. It then integrates large volumes of unstructured text data, such as customer feedback or social media posts into ML workflows for better decision-making.<\/li>\n\n\n\n<li>Amazon Transcribe converts spoken language into written text and extracts textual data from audio sources like customer service calls, interviews, or lectures, which can be used to train models.<\/li>\n\n\n\n<li>Amazon Lex helps in creating chatbots and virtual assistants and automates customer interactions with real-time responses.<br><br><\/li>\n\n\n\n<li>Amazon Polly will convert text into lifelike speech in multiple languages and voices and enhance accessibility by providing spoken content for applications.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Amazon Rekognition can identify objects, people, text, scenes, and activities in images and videos for advanced visual analysis and processing<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Final thoughts<\/strong><\/h2>\n\n\n\n<p>ML drives the practical application of AI by acting as a workhorse behind the scenes.
