A platform for deploying, managing, and scaling machine learning models in production on AWS infrastructure.
Cortex is a production infrastructure platform for machine learning that enables teams to deploy, manage, and scale ML models on AWS. It provides serverless APIs for real-time inference, async processing, and batch jobs while automating cluster management and observability. The platform reduces the operational overhead of running ML in production by handling scaling, monitoring, and infrastructure provisioning.
Machine learning engineers, data scientists, and DevOps teams who need to deploy and scale ML models in production on AWS infrastructure. It's particularly useful for organizations running multiple models or requiring high availability and cost efficiency.
Developers choose Cortex because it offers a specialized, AWS-native platform that abstracts away Kubernetes complexity for ML workloads. It provides built-in autoscaling, multi-environment support, and integrations with existing AWS services and monitoring tools, making it easier to operationalize models compared to building custom infrastructure.
Production infrastructure for machine learning at scale
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Built on EKS with deep integrations for VPC and IAM, simplifying deployment and security within AWS environments without manual Kubernetes tuning.
Provides serverless autoscaling for real-time, async, and batch workloads based on request volumes or queue length, optimizing costs and performance dynamically.
Enables creation of separate clusters for development, staging, and production with different configurations, ensuring safe and isolated model deployments.
Includes pre-built dashboards for Grafana and CloudWatch, plus log streaming, facilitating easy monitoring of model metrics and infrastructure health.
Supports running workloads on AWS spot instances with automated on-demand backups, significantly reducing inference costs for batch and async jobs.
Cortex is tightly coupled with AWS services like EKS and IAM, making it unsuitable for multi-cloud or hybrid deployments and creating significant vendor lock-in.
The project is no longer actively maintained, meaning no new features, bug fixes, or security updates, which poses operational risks for production systems.
Requires configuration of AWS EKS, VPC, and IAM, which can be steep for teams unfamiliar with AWS or Kubernetes, despite the abstraction layer.
The platform's advanced features like autoscaling and batch processing introduce unnecessary overhead for basic ML models with static or low traffic needs.
Cortex is an open-source alternative to the following products:
