Databases

DynamoDB at Serverless Scale

DynamoDB rewards careful design. We model tables around your access patterns so reads stay fast and costs stay predictable as traffic grows.

Overview

DynamoDB

Amazon DynamoDB is a fully managed NoSQL key-value and document database on AWS. It offers low-latency reads and writes, on-demand or provisioned capacity, global tables, streams and tight integration with Lambda, API Gateway and other AWS services. There are no servers to patch and no instances to size. Data is replicated across multiple availability zones within a region by default.

The trade-off is that DynamoDB has no ad hoc joins, so the data model must be designed around known access patterns. We start by listing those patterns, then design partition and sort keys, global secondary indexes and, where appropriate, single-table layouts. We pay attention to hot partitions, item size limits and consistency options, and set up TTL, streams and backups. We are candid when a relational database is the simpler answer.

Context

Why teams choose it

  • 01

    Fully managed operations

    No servers, patching or replication to manage; AWS handles scaling and durability.

  • 02

    Consistent low latency

    Key-based access stays fast regardless of table size when the model suits the workload.

  • 03

    Natural serverless pairing

    DynamoDB integrates directly with Lambda, Streams and API Gateway for event-driven designs.

  • 04

    Pay-per-use capacity

    On-demand mode matches spend to traffic, which suits spiky or unpredictable workloads.

Capabilities

What we build with it

  1. 01

    Access-pattern modeling

    Key design and single-table or multi-table layouts derived from your real queries.

  2. 02

    Secondary indexes

    Global and local secondary indexes chosen to support additional queries without waste.

  3. 03

    Serverless integration

    Lambda, API Gateway and EventBridge pipelines triggered by DynamoDB Streams.

  4. 04

    Capacity and cost tuning

    Choosing on-demand or provisioned capacity, and avoiding hot partitions and oversized items.

  5. 05

    Data lifecycle

    TTL expiry, point-in-time recovery, backups and exports to analytics storage.

  6. 06

    Global tables

    Multi-region replication for availability and latency across geographies.

Approach

How we work with it

  1. 1

    Assess

    We review your goals and any existing code to decide where this technology fits best.

  2. 2

    Architect

    We plan structure, integrations, data flow and hosting before writing production code.

  3. 3

    Build

    Features ship in small, reviewed increments with automated checks along the way.

  4. 4

    Release & maintain

    We deploy, monitor and keep dependencies and versions up to date.

FAQs

Common questions

Have a question that is not covered here? Get in touch.

Can DynamoDB replace a relational database?

Only when your access patterns are known and key-based. It does not support joins or flexible ad hoc queries, so workloads that need them are often better in PostgreSQL or MySQL.

What is single-table design?

It stores multiple entity types in one table, using key patterns to fetch related items in one request. It can be efficient but is harder to read and change, so we use it where the performance benefit is worth it.

How do costs work?

You pay for reads, writes and storage, either per request in on-demand mode or via provisioned capacity. Poor key design or large items can raise cost, which is why modeling comes first.

Does DynamoDB support transactions?

Yes, it offers transactional reads and writes across items, with limits on size and item count. We use them selectively because they cost more than standard operations.
