Featured Amazon DynamoDB reviews

Senior Engineering Consultant at ASSURANCE IQ, INC.

Previously, when in my company, we used to store 64 KB of data, we used to get problems and errors, and due to such reason, at such a point in time, we had to find a different storage system or modify the system so that the size of the value is not more than 64 KB. The main aforementioned issue in the tool can be considered for improvement for Amazon DynamoDB. In our company, we have some data which can be stored as we want. Previously, only 64 KB could be used, and later, I think, it was about 400 KB. If the tool could have an additional 10 MB to offer, then the tool could be easier to use. The tool is a key value storage, where the key will be long. In terms of value, we couldn't store more than 64 kb previously in the tool, but later on, it was increased to 400 KB, which is a limitation that I don't like in the tool.

There are a few areas of improvement. In future releases, I would like a feature that lets us store information about public holidays or weekends. When customers call during those closed periods, we could use DynamoDB to trigger an automatic message. It could say something like, "We're currently closed due to a holiday. Please call back during our regular working hours." So this would eliminate the need for agents to manually inform customers. With a holiday calendar stored in a DynamoDB table, we could write a Lambda function to check the date. If it's a UK holiday, for example, the system could automatically play the message.

We are currently consuming this data and storing it using coding. We are storing data in the database and retrieving those details. Everything is based on the EAP, but we are creating. There is no need to go to the particular TIN, DB, or application DB or search for the ID. Amazon DynamoDB does not currently offer any import functionality. However, users have requested this feature. For instance, if you have a large dataset stored in Excel and you wish to migrate it to DynamoDB, there is currently no direct import option available through the portal. Nevertheless, this limitation can be overcome using third-party tools such as AMP, which facilitates data importation into DynamoDB. Having an import option, whether through browsing or local file uploads, would significantly improve the efficiency of data migration, enabling users to swiftly transfer large volumes of data into DynamoDB.

Valuable Features

Amazon DynamoDB is praised for its fast, scalable performance and serverless architecture. It excels in handling unstructured data, offering flexibility without predefined schemas. Users appreciate its integration capabilities with other AWS services, low cost, and predictable millisecond response times. It supports NoSQL operations efficiently and allows dynamic updates to data attributes. The auto-scaling and low-cost model attract those seeking efficient, large-scale data management. Cloud integration with AWS simplifies tasks, enhancing functionality and reducing complexity.

"The fact that Amazon DynamoDB is highly scalable is one of its best features."
"Scalability has significantly enhanced data retrieval speeds."
"I appreciate the visibility of DynamoDB, as I can observe everything on the Console."

Room for Improvement

Amazon DynamoDB's documentation lacks clarity, particularly on basic topics, requiring updates. Users find the interface less user-friendly compared to competitors, needing an enhanced design. Encryption must be handled manually. Querying data can be challenging due to JSON syntax. Support for complex queries and better index management are desired. Data import functionality is missing, and scheduled data refreshes are absent. Cross-region replication requires coding, and pricing models should be more flexible for varied usage.

"Amazon DynamoDB can be quite expensive due to regional differences, so I have to be careful with the pricing."
"The user interface could be improved to make it more intuitive."
"As more data comes in, it becomes more expensive."

ROI

Organizations experience a good return initially with Amazon DynamoDB due to its reliability and scalability. It eliminates time-consuming database provisioning. Costs may increase with higher usage, and ROI is influenced by how it integrates with other systems. Personnel needs decrease because of automation and data replication features. While they do not profit directly from DynamoDB itself, their financial advantages come from professional services.

Pricing

Enterprise users of Amazon DynamoDB experience pricing based on usage and provisioned resources, making it flexible but complex. Costs can be low for small datasets but may rise significantly with high volume and feature use like global distribution and backups. Generally considered cheaper than high-end relational databases, users note that price is impacted by regional factors and data traffic. The pay-as-you-go model offers scalability, but expenses can grow with increased data demands.

"We previously paid around $20,000 a month for MongoDB, and now we're paying just $4,000 monthly for Amazon DynamoDB."
"I can say that it is not the cheapest one because if we had our own kind of storage solution, our own hosting, and instead of using the cloud, we opted for some other method, it would have been a tool of a lower cost."
"The solution's pricing is good, and it's not expensive."

Popular Use Cases

Organizations utilize Amazon DynamoDB for multiple purposes, including managing IoT data, non-relational databases, real-time analytics, and automation. It supports applications from weather data sensors and web-based services to managing structured and unstructured data. Companies use it to handle large-scale storage and retrieval needs, including streaming data, e-commerce, and localization data management. It's also ideal for fast storage, document classification, and integrating with other AWS services like Lambda for dynamic data handling.

Service and Support

Amazon DynamoDB's customer service and support are frequently praised for responsiveness and technical knowledge. Users appreciate quick solutions provided by both paid and standard support. Some note the need for local representatives and clearer communication when asking questions. Documentation and forums are valuable resources for many, while premium support offers real-time aid for enterprise needs. Occasionally, the support team may lack information, resulting in longer resolution times unless a paid support plan is utilized.

Deployment

Amazon DynamoDB's initial setup is described as straightforward by many. Some find it simple, while others mention requiring knowledge or a DevOps team. Setup times vary from minutes to weeks. Documentation and support ease the process, though some users seek external help. Deployment is quick with infrastructure as code tools. Challenges include understanding data design and anticipating future application growth, but AWS's offerings and support facilitate a manageable initial experience.

Scalability

Amazon DynamoDB is recognized for impressive scalability, accommodating workloads from small startups to large enterprises. Users consistently rate its scalability highly, often an eight or nine out of ten. Organizations successfully handle substantial data and user loads without encountering issues, thanks to AWS's management. Its architecture supports swift scaling, making it suitable even for high-demand environments. While some mention minor concerns with dynamic data storage, most appreciate its ability to manage peak throughput efficiently.

Stability

Amazon DynamoDB is widely acknowledged as a stable service. Many users rate its stability highly, often between seven and ten out of ten. They report no significant issues with crashes or bugs. While some minor configuration adjustments are needed, most appreciate its handling of high data volumes without latency. Although there are rare publicized downtimes, these are generally deemed acceptable and do not detract from its reputation for reliability.
