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 appreciated for scalability, cost efficiency, ease of use, and quick setup. Users highlight its capability to handle unstructured and semi-structured data, flexible schema-less design, and seamless integration with AWS services. Its serverless nature, document storage, secondary indexing, and transaction-based pricing are also valued. Furthermore, users emphasize its high-speed performance, real-time scalability, and efficient handling of large datasets.

"I appreciate the visibility of DynamoDB, as I can observe everything on the Console."
"DynamoDB is easy to configure, easy to use, and allows for writing data in JSON format."
"Being serverless, it alleviates concerns about scalability and failover."

Room for Improvement

Amazon DynamoDB needs improvements in documentation, user interface, and query capabilities. Enhanced encryption options and automated capacity scaling are desired. Users find the replication and integration processes complex and crave better import functionality, data recovery, and AI features. There's a need for more efficient pricing, improved spatial data representation, seamless cross-region data consistency, and support for larger data sizes. Users also suggest clearer guidance for setup, better backup features, and increased data import ease.

"As more data comes in, it becomes more expensive."
"Support is better if using a paid version."
"If you purchase the support plan, their support team is good. If not, it takes two to three days to respond, sometimes even more."

ROI

Users save time without provisioning databases, achieving ROI influenced by client implementations. Initial returns are strong but costs rise with extensive use. ROI varies with integration of Amazon DynamoDB and other systems. Investments bring reliability and scalability, essential for operations. Automation and data replication reduce personnel needs, leveraging existing features for regional data handling without additional measures.

Pricing

Enterprise buyers consider Amazon DynamoDB's pricing as complex and usage-based, with costs varying based on volume and provisioned throughput, offering a pay-as-you-go pricing model. While it's perceived as cheaper than some alternatives, costs can rise with high data volume or specific use cases. Some find it competitively priced and effective, especially when compared to traditional databases. Initial credits and free storage options may help, but global distribution and automated backups incur extra fees.

"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

Amazon DynamoDB is used for multiple purposes such as managing IoT data, database management, storing localization and e-commerce data, and supporting serverless functions. Users employ it for indexing large data, storing structured and unstructured information, automation, running applications, and normalizing data. It's favored for its scalability and NoSQL capabilities, accommodating both JSON data and document databases. Many integrate it with AWS services like Lambda and use it for data analytics and tracking.

Service and Support

Amazon DynamoDB's customer service and support are primarily praised for responsiveness and effectiveness, with ratings often between 4 to 10 out of 10. Support is more efficient with a paid plan, often resolving issues within 40 minutes via email or chat. Documentation is helpful; some find it self-explanatory. Instances of support lacking sufficient knowledge are noted, and there's feedback on improving local support and understanding specific use cases. Overall, many users find it satisfactory.

Deployment

Many users found Amazon DynamoDB's initial setup to be straightforward, highlighting the simplicity and speed of deployment. Some noted that knowledge of DevOps and data requirements is helpful, while others mentioned that minimal resources are needed for maintenance. A few users experienced complexity, especially without prior expertise, but overall, easy access through cloud services and proper documentation helped streamline the process, allowing rapid setup and integration.

Scalability

Amazon DynamoDB exhibits strong scalability, accommodating both small businesses and large enterprises. Users report minimal scalability issues, rating it highly. Although it handles spikes effectively, some limitations in data size impact performance for specific use cases. The service adjusts smoothly to high traffic demands and manages user data efficiently, maintaining peak throughput. DynamoDB's scalability supports a wide range of applications, ensuring users need not worry about managing infrastructure or experiencing significant performance concerns.

Stability

Amazon DynamoDB is widely regarded as stable. Users frequently report smooth performance without issues. Occasional downtime is noted but considered acceptable. Exceptions may occur when exceeding provisioned throughput, handled by retries with exponential backoff. Managed by Amazon, stability often rates high on a ten-point scale. Companies experience seamless data handling, scalability, and minimal latency. Instabilities are rarely reported, with only a few mentioning configuration challenges or publicized service disruptions. Overall, stability satisfaction is prominent.
