In this post, we show how to optimize capacity by analyzing EMR workloads and implementing strategies tailored to your workload patterns. We walk through assessing the historical compute usage of a workload and use a combination of strategies to reduce the likelihood of InsufficientCapacityExceptions (ICE) when Amazon EMR launches specific EC2 instance types. We implement flexible instance fleet strategies to reduce dependency on specific instance types and use Amazon EC2 On-Demand Capacity Reservation (ODCRs) for predictable, steady-state workloads. Following this approach can help prevent job failures due to capacity limits while optimizing your cluster for cost and performance.

Amazon EMR has introduced new features for instance fleets that address critical challenges in big data operations. This post explores how these innovations improve cluster resilience, scalability, and efficiency, enabling you to build more robust data processing architectures on AWS.

Fine-grained access control is a crucial aspect of data security for modern data lakes and data warehouses. As organizations handle vast amounts of data across multiple data sources, the need to manage sensitive information has become increasingly important. Making sure the right people have access to the right data, without exposing sensitive information to unauthorized […]
