• Serverless Architecture and Scalability:

The fully managed, serverless nature of DynamoDB eliminates the need to manage server infrastructure. The ability to automatically scale resources up or down to meet application demand is exceptional, ensuring performance remains consistent, even with unpredictable workloads.

• Predictable Performance: It delivers consistent, single-digit millisecond latency at any scale. This makes it an ideal choice for mission-critical applications such as e-commerce, gaming, and real-time services where performance is paramount. During high-traffic events, its reliability is proven.

• Global Tables and High Availability:

The Global Tables feature allows for multi-master, multi-region replication, which is crucial for building highly available, globally distributed applications. Replicating data across three different Availability Zones (AZs) by default ensures robust durability and resilience.

• Integrated Security:

Security is robust, with encryption at rest and in transit, along with tight integration with AWS Identity and Access Management (IAM) for granular access control.

• Flexibility and Integration:

As a NoSQL db, it offers flexibility in the data schema, which is beneficial during development when data structures may evolve. It integrates seamlessly with other AWS services like Lambda and others enhancing its overall functionality. Review collected by and hosted on G2.com.

My main challenge with DynamoDB has been mastering its cost and performance optimization.

While the pay-per-request model is incredibly flexible, it also means that you have to be vigilant. It’s easy for costs to escalate if you’re not careful about how you design your queries.

An inefficient table scan or a “hot key” that gets accessed too frequently can quickly lead to throttled requests and a surprisingly high bill. Review collected by and hosted on G2.com.

The wide range of database options (RDS, DynamoDB, Aurora, etc.) makes it easy to choose the right tool for each use case—whether relational, NoSQL, or in-memory. The automated backup, scaling, and patching features reduce operational overhead significantly. Additionally, the seamless integration with other AWS services enhances data workflows and security.

Pricing can become unpredictable with high workloads, especially with on-demand provisioning and data transfer costs. The learning curve is also steep for newcomers due to the wide variety of services and configuration options. Additionally, debugging or troubleshooting performance issues may require deep expertise or reliance on AWS support. Review collected by and hosted on G2.com.

AWS Cloud is scalable , reliable and has massive service ecosystem. It allows you to spin up environments within minutes and automate deployments with cloud formation of terraform and manage infrastructure through a highly configurable IAM model Review collected by and hosted on G2.com.

The pricing structure can be confusing and hard to estimate for complex setups Review collected by and hosted on G2.com.

AWS databases are fully managed, highly scalable, and secure, offering a wide range of purpose-built options like RDS, DynamoDB, and Redshift. They reduce operational overhead, support high availability, and integrate seamlessly with other AWS services—making it easy to build reliable, performant applications at scale.

EAWS databases can become expensive at scale, especially with high I/O or storage needs. Some services have complex pricing models and limits (like DynamoDB throughput). Also, vendor lock-in and limited customization compared to self-managed databases can be concerns for some users. Review collected by and hosted on G2.com.

DynamoDB is a serverless database service that simplifies coding by eliminating server management. It automatically scales to handle traffic spikes, ensuring fast performance even under heavy load. Its flexible data model allows easy changes without a rigid structure. As a managed AWS service, it handles administrative tasks and integrates well with other AWS tools. For global reach, the Global Tables feature makes data accessible worldwide, and DynamoDB Streams enables real-time change tracking. Review collected by and hosted on G2.com.

Performing complex searches and combining data can be challenging. It's crucial to organize your data properly for easy access. There's no built-in option to run code directly in the database, which complicates multi-step tasks. Monitoring costs can be tricky, so stay vigilant about your expenses. While the system scales automatically, you may encounter "hot spots" that need attention. For full-text searching, you'll need to use an external service. Lastly, changing your data structure can be delicate due to the lack of strict guidelines. Review collected by and hosted on G2.com.

The most helpful feature about Dynamo DB is one of it's standout features of unparalleled scalability. With the ability to handle petabytes of data and support millions of requests per second, DynamoDB effortlessly scales to meet the demands of even the most demanding workloads. Whether it's a small-scale application or a global enterprise solution, DynamoDB adapts seamlessly to evolving data requirements, eliminating the need for manual provisioning or capacity management.

Pricing model is very complex to understand. Review collected by and hosted on G2.com.

The single best aspect of Amazon DynamoDB is its unparalleled scalability and predictable performance at any traffic volume. Review collected by and hosted on G2.com.

Steep Data Modeling Learning Curve and Querying Limitations Review collected by and hosted on G2.com.

Fully managed and highly scalable and good nosql Review collected by and hosted on G2.com.

It is complex to manage we might have to write complex queries Review collected by and hosted on G2.com.

It was rather easy to kick it off. Even for devs with 0 expirience in DynamoDB Review collected by and hosted on G2.com.

Rather hard to adopt it for any unexpected needs. By the end of the day we understood that a simple SQL DB would be much more flexible for us, since we were testing different features mostly and scalability was not our primary focus. So a monolite approach would be much more efficiennt for us. Review collected by and hosted on G2.com.
