Let’s Architect! Architecting with Amazon DynamoDB

NoSQL databases are an essential part of the technology industry in today’s world. Why are we talking about NoSQL databases? NoSQL databases often allow developers to be in control of the structure of the data, and they are a good fit for big data scenarios and offer fast performance.

In this issue of Let’s Architect!, we explore Amazon DynamoDB capabilities and potential solutions to apply in your architectures. A key strength of DynamoDB is the capability of operating at scale globally; for instance, multiple products built by Amazon are powered by DynamoDB. During Prime Day 2022, the service also maintained high availability while delivering single-digit millisecond responses, peaking at 105.2 million requests-per-second. Let’s start!

Data modeling with DynamoDB

Working with a new database technology means understanding exactly how it works and the best design practices for taking full advantage of its features.

In this video, the key principles for modeling DynamoDB tables are discussed, plus practical patterns to use while defining your data models are explored and how data modeling for NoSQL databases (like DynamoDB) is different from modeling for traditional relational databases.

With this video, you can learn about the main components of DynamoDB, some design considerations that led to its creation, and all the best practices for efficiently using primary keys, secondary keys, and indexes. Peruse the original paper to learn more about DyanamoDB in Dynamo: Amazon’s Highly Available Key-value Store.

Single-table vs. multi-table in Amazon DynamoDB

When considering single-table versus multi-table in DynamoDB, it is all about your application’s needs. It is possible to avoid naïve lifting-and-shifting your relational data model into DynamoDB tables. In this post, you will discover different use cases on when to use single-table compared with multi-table designs, plus understand certain data-modeling principles for DynamoDB.

Optimizing costs on DynamoDB tables

Infrastructure cost is an important dimension for every customer. Despite your role inside an organization, you should monitor opportunities for optimizing costs, when possible.
For this reason, we have created a guide on DynamoDB tables cost-optimization that provides several suggestions for reducing your bill at the end of the month.

Build resilient applications with Amazon DynamoDB global tables: Part 1

When you operate global systems that are spread across multiple AWS regions, dealing with data replication and writes across regions can be a challenge. DynamoDB global tables help by providing the performance of DynamoDB across multiple regions with data synchronization and multi-active database where each replica can be used for both writing and reading data.

Another use case for global tables are resilient applications with the lowest possible recovery time objective (RTO) and recovery point objective (RPO). In this blog series, we show you how to approach such a scenario.
