Ease of creating APIs with ongoing updates needed for automation
AWS has made it easy for developers like me to create and manage GraphQL APIs. The ease of use is a main advantage, allowing even beginners to start from scratch and learn through AppSync. Before AWS, developing and managing APIs was quite complex. AWS provided AppSync, which assists developers and startup founders. Startups blooming everywhere benefit from this service, welcoming those who lack prior knowledge. When working on AWS, I notice that Amazon regularly implements new features. For instance, with the Lambda service, AWS is transitioning from an old editor to a new one. Similarly, AppSync frequently introduces updates and changes. This trend is making the user interface more accessible, even for individuals without a technical background. Additionally, the cost is attractive, as AWS operates on a pay-as-you-go basis. These factors make AppSync both easy to use and cost-effective.

Has simplified multi-database querying and accelerated solution delivery with minimal setup
Denodo offers a great query language, the VQL, which was very easy to understand for someone that only knows SQL. It was easy to work with, and it was easy to integrate various types of databases in general. The usability of the platform is very great. The federated queries were also a feature that I used a lot. The easy usability of Denodo helped my work and made things easier for productivity. We were able to ship code faster than if we needed to use another type of data visualization tool or even an ETL. When we have multiple databases, the standard or common approach is just to have an ETL that matches the data, and we need to write this whole ETL. With Denodo, we can simplify this whole work to a few queries or setups in the databases and just make a few queries. This was actually easier, and it was faster to deliver a solution for a client instead of building a whole ETL pipeline or simply backfilling one database in another. Denodo simplifies your work and helps you ship code or ship solutions in a faster way. I really like the UI that Denodo has on the web app version. It was very simple and actually very beautiful to see. For a complicated program, it was very easy to understand how it works, even for someone who is just approaching the data engineering career or side of the programming language.

Pros

"AWS has made it easy for developers like me to create and manage GraphQL APIs."
"AWS has made it easy for developers like me to create and manage GraphQL APIs."
"Support for multiple data sources and formats is a fantastic feature."
"Data mining is one of the valuable features. We're able to connect all of the data sources with the installed driver, so that is a good advantage in Denodo. Being able to join the tables and view them is also valuable."
"It is easy to virtualize data using the solution."
"The most valuable aspects of this solution are the short time frame in which you can deliver and connect."
"The data catalog feature is valuable as it helps define data structures without storing data."
"It is a go-to tool for data virtualization. The virtualization and data catalog are the features of why we chose Denodo."
"The most valuable feature in Denodo is data virtualization."
"Denodo simplifies your work and helps you ship code or ship solutions in a faster way."
"Access to numerous forums and internet information."
 

Cons

"In AppSync, assigning roles and permissions to APIs is necessary for accessing other AWS services. Automating this task when creating APIs would be beneficial."
"Moving to other clouds is impossible without significantly rearchitecting your applications."
"In AppSync, assigning roles and permissions to APIs is necessary for accessing other AWS services. Automating this task when creating APIs would be beneficial."
"The solution should have its own acceleration technology."
"The feature that you have to connect on LDAP needs improvement."
"While AI and ML integration is present, understanding its implementation better could be beneficial."
"Monitoring event logs can be improved. In the older version, there was a monitoring schedule to get event reports and properly audit the reports. In the newer version, it is not there, and we have to manually configure data and audit events."
"The integration could use improvement, it's a lot of non-speed line processes that we have discovered, in the country. The configurations could use a lot more improvement."
"Data transformation must be improved."
"Denodo currently integrates with ChatGPT, but the ability to manage and utilize them directly within Denodo would be a significant improvement."
"Denodo has some difficulty supporting large numbers of records."
 

Pricing and Cost Advice

"Licensing fees are paid on a monthly basis, and it is a pay-as-you-go model."
"Cost wise, on a scale from one to five, with one being the cheapest and five being the most expensive, Denodo would be at three. We get all the features in a bundle."
"For us, the cost has been okay. Also, there are no additional costs; it's just the standard licensing fee."
"The cost for Denodo is in line with other similar products."
"The licensing charges for this solution are payable annually."
"Depending on the size of the client you want to work with, it can be prohibitively expensive at times."
"The pricing is pretty good, and I would rate it at four out of five."
"The licensing should be improved, as the cost per connector is quite expensive."
"I am not super familiar with the pricing, but so far, it seems good. We have been happy. We haven't seen any problems. The only time we had to pay extra was during the upgrade. We didn't upgrade at the time they told us to upgrade, and we had to pay extra to keep the service. They had stopped the support for the older version and moved to the newer version. It was not their fault. It was our fault because we didn't get on board quickly."
