Creating a REST API for Amazon DocumentDB (with MongoDB compatibility) with Amazon API Gateway and AWS Lambda
Representational state transfer (REST) APIs are a common architectural style for distributed systems. They benefit from being stateless and therefore enable efficient scaling as workloads increase. These convenient—yet still powerful—APIs are often paired with database systems to give programmatic access to data managed in a database. One request that customers have expressed is to have […]
Read MoreAmazon DocumentDB (with MongoDB compatibility) read autoscaling
Amazon Document DB (with MongoDB compatibility) is a fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads. Its architecture supports up to 15 read replicas, so applications that connect as a replica set can use driver read preference settings to direct reads to replicas for horizontal read scaling. Moreover, as […]

This is a guest post by David Ting, VP of Engineering at Nylas. In their own words, Nylas is a pioneer and leading provider of universal communications APIs that allow developers to quickly connect their applications to every email, calendar, or contacts provider in the world. Over 26,000 developers around the globe use the Nylas […]
Read MoreBuilding enterprise applications using Amazon DynamoDB, AWS Lambda, and Go
Amazon DynamoDB is a fully managed service that delivers single-digit millisecond performance at any scale. It is fully managed, highly available through behind-the-scene Multi-AZ data replication, supports native write-through caching with Amazon DynamoDB Accelerator (DAX) as well as multiple global secondary indexes. Developers can interact with DynamoDB using the AWS SDK in a rich set […]
Read MoreIAM role-based authentication to Amazon Aurora from serverless applications
Storing user names and passwords directly in applications is not a best practice. Saving credentials as plaintext should never occur in a secure application. As a solution, AWS Identity and Access Management (IAM) policies can assign permissions that determine who is allowed to manage Amazon Aurora resources. For example, you can use IAM to determine […]
Read MoreRunning AWS Lambda-based applications with Amazon DocumentDB
Microservices-based applications architectures are the norm for building scalable applications. AWS makes creating these types of applications easier with Amazon DocumentDB (with MongoDB compatibility). Just bring your code and deploy an application with this fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads. You can use the same MongoDB application […]
Read MoreMonitor Amazon ElastiCache for Redis (cluster mode disabled) read replica endpoints using AWS Lambda, Amazon Route 53, and Amazon SNS
In Amazon ElastiCache for Redis, your applications use the provided endpoints to connect to an ElastiCache node or cluster. According to Amazon ElastiCache for Redis Components and Features in the ElastiCache for Redis User Guide, a multiple-node Redis (cluster mode disabled) cluster has two kinds of endpoints: “The primary endpoint always connects to the primary […]
Read MoreStream changes from Amazon RDS for PostgreSQL using Amazon Kinesis Data Streams and AWS Lambda
In this post, I discuss how to integrate a central Amazon Relational Database Service (Amazon RDS) for PostgreSQL database with other systems by streaming its modifications into Amazon Kinesis Data Streams. An earlier post, Streaming Changes in a Database with Amazon Kinesis, described how to integrate a central RDS for MySQL database with other systems […]
Read MoreUse Amazon DynamoDB Accelerator (DAX) from AWS Lambda to increase performance while reducing costs
April 01, 2020 update: Changed the security to add a least privileged IAM policy to the role instead of a wide open managed policy, switched to HttpApi in API Gateway for auto-deployment as well as cost, and added to node.js code to detect if a requesting client is base64 encoding the body of the request and […]
