Amazon Neptune is a fully managed graph database service built for the cloud that makes it easier to build and run graph applications that work with highly connected datasets. Neptune provides built-in security, continuous backups, serverless compute, and integrations with other AWS services. Neptune supports in-place upgrades of cluster and database instances. Upgrade of a Neptune cluster can be done either manually or automatically (during the database maintenance window).

Today’s modern applications are expected to be scalable and resilient. The top of this list is scalability, which depending on the size of the application workload could mean the ability to handle millions of users on demand. With stateful applications such as eCommerce, Financial Services and Games, this means having highly available databases. With the release of Amazon Aurora in 2015, customers could run relational databases in an Aurora cluster comprising of one writer and up to 15 low-latency reader nodes. This enables applications to scale reads significantly. However, as with any database supporting multiple instances, developers have built complex application logic to deal with special events such as switchover or failover.

Amazon DocumentDB (with MongoDB compatibility) is a fast, reliable, and fully managed database service. Amazon DocumentDB makes it easy to set up, operate, and scale MongoDB API-compatible databases in the cloud. With Amazon DocumentDB, you can run the same application code and use the same drivers and tools that you use with MongoDB API. Performance Insights adds to the existing Amazon DocumentDB monitoring features to illustrate your cluster performance and help you analyze any issues that affect it. With the Performance Insights dashboard, you can visualize the database load and filter the load by waits, query statements, hosts, or application. Performance Insights is included with Amazon DocumentDB instances and stores seven days of performance history in a rolling window at no additional cost.

In this post, we demonstrate how to create custom PostgreSQL data types using TLE. PostgreSQL ships with many robust data types that accommodate most customer workloads in a performant manner. Although PostgreSQL has the capabilities to deploy custom data types natively, introducing new data types at scale in architectures spanning multiple AWS accounts and Regions poses a unique challenge for builders. With Trusted Language Extensions (TLE), you can create and manage your custom data types, allowing the quick and easy deployment of PostgreSQL data types across your infrastructures in a secure and efficient manner.

In this post, we show you how to use a secondary replica instance in an Always On availability group as the source of migrating your data from SQL Server to Amazon Redshift. Using a secondary replica reduces the utilization overhead on your busy primary replica.

This post describes a methodology to transform and migrate data from a relational database like Amazon Relational Database Service (Amazon RDS) for MySQL to a non-relational database like Amazon DocumentDB (with MongoDB compatibility) using AWS Glue.

In this post, we discuss some recommended solutions and practices you should adopt in order to protect your databases hosted on Amazon RDS for Oracle from database block corruption.

When working with Amazon DynamoDB, developers have the option to choose between a low-level client and a high-level client in most of the AWS SDKs offered. Understanding the differences between these client types is crucial for effectively interacting with DynamoDB. In this post, we explore the characteristics, use cases, and benefits of both low-level and […]

Continuous integration and continuous delivery (CI/CD) is a process that automates software development workflows and deploys better quality software that avoids bugs and code failure. CI/CD removes the manual human intervention that was traditionally needed to get code changes from development environments to production servers. With a CI/CD pipeline, code changes are automatically detected, built, […]
