AWS Amazon DynamoDB FAQs: Cost, Training, Value

What is Amazon DynamoDB?

Amazon DynamoDB is a fully managed NoSQL database service provided by Amazon Web Services (AWS). DynamoDB's emphasis is on scalability, high availability and low-latency performance for apps that require especially fast and predictable data storage and retrieval. DynamoDB has a flexible schema design thanks to its key-value and document data model, which means it's a favorite for real-time applications, gaming, Internet of Things, and other high-throughput, low latency demands.

What is the biggest advantage to using DynamoDB?

DynamoDB's biggest selling point and biggest advantage is its seamless scalability and high performance. DynamoDB is a fully managed NoSQL database service, which means it handles infrastructure provisioning and scaling on the fly and based on dynamic demands. The benefit to investing in DynamoDB is low-latency responses even during heavy load. Additional advantages to DynamoDB include its flexible schema design along with features like global tables and multi-region replication.

What is the biggest disadvantage to using DynamoDB?

Cost and cost structure is DynamoDB's biggest disadvantage. Obviously there are safeguards and limits in place, but costs can escalate significantly when data storage and access requirements spike. The high performance and scalability that make DynamoDB an excellent choice for high throughput apps means it's also a luxury: applications with large datasets and frequent access patterns can become expensive. DynamoDB also has limited query capabilities when compared to some other databases.

What can be stored in DynamoDB?

DynamoDB accommodates many different data types, from strings, numbers, and binary data, to sets and documents. DynamoDB supports simple key-value pairs as easily as complex nested structures like JSON. This width and breadth means all manner of information can be stored: user profiles, catalogs, sensor readings, and session data. Because it can support structured and semi-structured data, DynamoDB is a good choice for diverse applications needing fast and scalable data storage.

Who should take this course on Amazon DynamoDB?

IT professionals who work in software development, database administration, and cloud administration would all benefit from this course. If you develop apps with high scalability needs, if you design cloud-native solutions for complex storage networks, or if you're a data engineer managing large datasets, this course can help you unlock DynamoDB's benefits and advance your career. Anyone interested in a career related to AWS services would also benefit.
