Scalable cross-cloud data migration to Amazon S3 with distributed rclone

Migrating petabytes of data across cloud providers is one of the most operationally demanding tasks an organization can take on. At this scale, simple transfer approaches break down. Teams lose track of what has been copied and what has failed. Transfers stall and require constant manual intervention to restart. In some cases, teams need to […]

Implement single-exchange tokens for short-lived Amazon S3 presigned URLs with Terraform

Organizations across industries use signed URLs to grant temporary, credential-less access to private resources such as receipts, medical or financial records, legal files, or confidential reports. However, signed URLs can be reused by anyone until they expire, creating security risks if a URL is shared or inadvertently disclosed. This risk can be mitigated by vending […]

Troubleshooting Amazon S3 access denied errors using Kiro CLI

Managing data access across multiple layers of permissions is a common industry challenge. Changes to AWS Identity and Access Management (AWS IAM) policies, Amazon Simple Storage Service (Amazon S3) bucket configurations, AWS Key Management Service (AWS KMS) key policies, or Amazon Virtual Private Cloud (Amazon VPC) endpoint policies can unintentionally cause access issues. When these […]

Accelerate Apache Hadoop and Apache Iceberg on Amazon S3 with the Analytics Accelerator Library

Organizations processing large-scale data for analytics, machine learning (ML), and business intelligence face a persistent challenge: how to access and read massive datasets quickly and cost-effectively. As data volumes grow exponentially, the performance of data access patterns becomes more critical. Inefficient read operations can lead to longer processing times, higher compute costs, and delayed insights, […]
