Deploy Oracle Database step by step on Amazon EVS with FSx for ONTAP
This post provides step-by-step procedures to deploy Oracle Database on Amazon Elastic VMware Service (Amazon EVS) with Amazon FSx for NetApp ONTAP as NFS datastore storage. You provision storage volumes, mount NFS datastores, install Oracle, and configure SnapMirror replication for cross-region disaster recovery.
Architect highly available Oracle Database on Amazon EVS and FSx for ONTAP
Learn how to architect a highly available Oracle Database environment on Amazon Elastic VMware Service (Amazon EVS) with Amazon FSx for NetApp ONTAP. This post covers EC2 bare metal instance selection, vSAN and FSx storage tiering, NSX networking, and SnapMirror cross-region disaster recovery for enterprises preserving their VMware operational tooling.
Running multi-day AZ evacuation drills with ARC Zonal Shift
Prove your multi-AZ architecture can sustain a real impairment. This post shows how to run a multi-day (48-72 hour) Availability Zone evacuation drill with ARC Zonal Shift across Amazon ECS, Amazon EKS, Amazon RDS for PostgreSQL, and Amazon Aurora PostgreSQL, with step-by-step CLI commands, prerequisites, observability metrics, and restore procedures.
Building cloud-native PACS on AWS
A hybrid cloud architecture pattern for modernizing medical imaging on AWS. Learn how multi-hospital networks can centralize PACS archives, enable cross-facility interoperability, and use Amazon S3 storage tiers to manage cost and retention at scale.
From zero-shot forecast to purchase order with Amazon Bedrock AgentCore
Combine zero-shot forecasting with Amazon Chronos2 and multi-agent orchestration on Amazon Bedrock AgentCore to turn demand forecasts into validated purchase orders. No per-product model training, with business rules, auditability, and cost that scales to zero.
Building resilient real-time streaming workers with Amazon DynamoDB leases
Real-time streaming workers that hold hundreds of persistent WebSocket connections lose data when a worker fails. Learn how to build a WebSocket fleet management system on Amazon ECS and AWS Fargate that uses Amazon DynamoDB conditional writes as a distributed lease to track ownership, fail over automatically, and deploy with low downtime.
Testing application resilience with Amazon SQS and AWS Fault Injection Service
Learn how to use AWS Fault Injection Service and AWS Systems Manager Automation to run progressive chaos experiments against Amazon SQS queues. Validate that your retry logic, circuit breakers, and dead-letter queues actually work under failure before a real outage hits production.
Validating multi-Region DR for Terraform Enterprise with AWS FIS
Learn how AWS, HashiCorp, and Athenahealth designed and chaos-tested a multi-Region disaster recovery strategy for Terraform Enterprise on AWS. This post walks through three-phase AWS Fault Injection Service experiments across Amazon EC2, Aurora, and Amazon S3, the 12-14 minute recovery times achieved, and the state file dependency pitfall to avoid.
Build a unified AI agent architecture with DynamoDB and Bedrock
With native vector search in Amazon DynamoDB, you can store vector embeddings alongside your operational data in a single table. This post shows how to build a unified AI agent architecture where an Amazon Bedrock agent uses one DynamoDB table for both structured lookups and semantic search, with a DynamoDB Streams pipeline that keeps embeddings in sync.
How AgentFlo built AI sales agents with Amazon Bedrock AgentCore – Part 2
Part 2: how AgentFlo built trusted, reliable AI sales agents on Amazon Bedrock AgentCore and AWS serverless architecture. Learn the three-layer guardrails, grounded data foundation, and end-to-end observability behind a +12% net revenue uplift, plus what’s next for real-time voice and server-side tool execution.
