In this post, we discuss how to perform aggregations on a DynamoDB table using Amazon DynamoDB Streams and AWS Lambda. The content includes a reference architecture, a step-by-step guide on enabling DynamoDB Streams for a table, sample code for implementing the solution within a scenario, and an accompanying AWS CloudFormation template for easy deployment and testing.

The first question that comes up for everyone who wants to manage their own Ethereum nodes on AWS is how to select the right compute and storage. To answer this question, we ran a series of tests and observed how popular Ethereum Execution Layer (EL) clients go-ethereum with LevelDB (Geth) and Erigon work on Amazon […]

SAP SQL Anywhere (also known as Sybase SQL Anywhere) is a database which is widely used in Information Technology and Services industry.

The new proof-of-stake consensus mechanism on Ethereum blockchain network allows network participants to earn rewards without spending a lot of computational power for playing a part in securing the network. Unlike miners, validators don’t need to spend many CPU cycles to produce new blocks. They stake 32 ETH (the native cryptocurrency on Ethereum) to be […]

In this post, you learn how to deploy a cloud-based development environment with which to build, test, and deploy smart contracts on the public Ethereum Goerli testnet via a dedicated Ethereum full node managed using Amazon Managed Blockchain. You can also use the steps outlined in this post to create a development environment on the […]

This is the second in a two-part series about scaling applications globally using multi-Region Amazon Elastic Kubernetes Service (Amazon EKS) and Amazon Aurora Global Database. In Part 1, you learned the architecture patterns and foundational pillars of a multi-Region application design. In this post, we use the read local and write global design pattern to scale, […]

In this post, we advance the architecture that was discussed in Implement active-active replication with RDS Custom for Oracle: Part 1 – High Availability, where we implemented an Amazon RDS Custom for Oracle solution with multi-master and high availability. This post will show you how to add high availability (HA) and disaster recovery (DR) using Oracle […]

July 2023: This post was reviewed for accuracy. Amazon Virtual Private Cloud (Amazon VPC) enables you to provision a logically isolated section of theAWS Cloud where AWS resources such as Amazon Relational Database Service (Amazon RDS) DB instances can be launched in a virtual network you define.
