While migrating workloads from the Azure Cloud to the AWS Cloud, organizations explore optimal, managed database services to replace their Cosmos DB databases. As NoSQL databases become more ubiquitous, especially those that support the Apache 2.0 open-source MongoDB APIs, our customers often choose Amazon DocumentDB because it’s a scalable, highly durable, and fully managed database […]

You can use open source monitoring solutions like Telegraf, InfluxDB, and Grafana to monitor your applications and databases running on-premises or on Amazon Elastic Compute Cloud (Amazon EC2). In this post, we explain how you can leverage these tools on Amazon Relational Database Service (Amazon RDS) Custom for SQL Server. Use of open source software […]

In Part 1 of this series, you learned about Amazon DynamoDB data loading strategies and the behavior of DynamoDB during short runs. In Part 2, you learned about query performance and the adaptive behavior of DynamoDB during sustained activity. In this third and final post, we review what you’ve learned, plus offer a few additional […]

In the Part 1 of this series, you learned about Amazon DynamoDB data loading strategies and the behavior of DynamoDB during short runs. In this post, you learn about query performance and the adaptive behavior of DynamoDB during sustained activity. Querying To drive traffic at arbitrarily large rates and simulate real-world behavior, we need a […]

The general rule with Amazon DynamoDB is to choose a high cardinality partition key. But why; and what happens if you don’t? Inspired by a customer use case, we dive deep into this question and explore the performance of loading and querying DynamoDB using different partition key designs and table settings. After each experiment, we […]

Customers who are considering migrating their Azure Cosmos DB workloads to Amazon DynamoDB ask what differences to expect. In this post, we discuss the differences to expect and plan for when migrating from Azure Cosmos DB to DynamoDB. DynamoDB is a serverless key-value database optimized for common access patterns, typically to store and retrieve large […]

A common challenge faced by customers migrating their application to a new Amazon Relational Database Service (Amazon RDS) for Oracle environment is unexpected performance degradations caused by query plans changes. Any of the following migration factors can lead to query plan digression and in this post, we outline a strategy to proactively address these stumbling […]

As customers migrate their Oracle databases to the Amazon Relational Database Service for Oracle, they may often benefit from a shared file system to be available on their Oracle database systems. This is either to share files between the database and application servers or to act as a staging location to keep backups, data loads, […]
