Like a laboratory where scientists can experiment with cutting-edge equipment without buying it, Amazon Braket lets researchers and developers explore quantum algorithms using gate-based quantum computers (from IonQ and Rigetti), quantum annealers (from D-Wave), and high-performance simulators — all through a unified API. The service includes a managed Jupyter notebook environment for developing and testing quantum circuits before running them on actual quantum hardware.

An AI-powered integrated development environment (IDE) from AWS that uses a spec-driven approach to software development. Instead of jumping straight into code, Kiro guides developers through a structured workflow: describe what you want to build in natural language, review generated specifications and designs, then produce production-ready code with tests and documentation. Kiro includes AI agent capabilities for code generation, debugging, and refactoring, along with automation features called hooks that trigger actions based on development events. It aims to bridge the gap between planning and building by combining specification management with AI-assisted coding.

Core services include Apache Kafka (AWS MSK, Confluent), AWS Kinesis, GCP Dataflow, Azure Stream Analytics, and Apache Flink.

The movement of data between cloud services, regions, availability zones, or between the cloud and the internet. Egress (data leaving a cloud) typically incurs costs; ingress (data entering) is usually free. Understanding data transfer pricing is critical for cost optimization — cross-region transfers, CDN distribution, and Direct Connect/ExpressRoute can significantly impact cloud bills.

Long-term, cost-optimized storage for data that is rarely accessed but must be retained — typically for compliance, legal, or historical purposes. Archival storage tiers offer the lowest cost per GB but have slower retrieval times (minutes to hours). Key services: AWS S3 Glacier / Glacier Deep Archive, Azure Archive Storage, GCP Archive Storage, OCI Archive Storage.

The process of identifying, assessing, and mitigating risks to cloud infrastructure, data, and operations.
