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.

Streamlines data migration across platforms with cost-effective and scalable solutions
We have the continuous data integration feature, but it does not work very well in our given ecosystem because we have huge data volume, and it reads from archive log rather than the redo sequence. That is where it lacks, so we are not able to do continuous streaming data injection. The ability to handle heterogeneous migrations for our organization is adequate. I do not see a major value add, or see it as a marquee feature. It is a good tool, but we do not have that sort of uses requirement. In my 10 plus years of experience, I do not see that kind of requirement where I have to replicate it in real time. I leverage AWS CloudWatch for addressing migration issues. The major challenges come across CDC. We have created latency filter and everything, but there is no way to control it. Due to the nature of our business, the transactions increase during month end and year end. My transactions are supposed to increase, my workloads on my core system increases, but my DMS is not able to keep up with them, even if I increase it to a higher side. Improvements could be made in AWS Database Migration Service. Because of that, I am moving out of DMS now to a STRIIM solution. DMS works within AWS ecosystem, but they also have to look for third party solutions. Now Snowflake is a bigger player, or Databricks. Something that could be possible as a connector, whether paid or free, but giving as a connector to that ecosystem as well.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"What I find most valuable in AWS Database Migration Service are these features: the full load and continuous data replication to heterogeneous endpoints."
"One of the features, I find most valuable is its ability to apply rules and transformations to data during real-time integration. This includes changing schema names or table structures on AWS without delaying the data flow. Initially, full migrations can vary widely in time depending on the source system; for instance, a large Magento database might take up to six months, while smaller databases like IBM DB2 could migrate within hours. Once set up, AWS DMS ensures real-time synchronization using Change Data Capture (CDC), maintaining data integrity throughout the process."
"One valuable feature of AWS Database Migration Service is change data capture (CDC)."
"For our simple requirement of migration, DMS is just a typical AWS RDS with an IPSec tunnel to Oracle. The most valuable features for us are the networking capabilities like VPCs and VPNs."
"The solution is stable and reliable."
"It's scalable."
"AWS Database Migration Service is good for smaller workloads and provides compatibility."
"This solution is very good at mini-batch processing."
 

Cons

"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."
"There is no connectivity to the source database or the target database."
"The names of the services need improvement since AWS doesn't indicate what the function of the product is presently. You need to read a lot to find the service that you want in the product."
"The performance of data migration could be smoother."
"I only used AWS DMS over the course of about three months, but I could tell that it's not always stable."
"In my experience, AWS Database Migration Service performs well for its primary purpose of data migration. One area that could be improved is its support for non-AWS file formats, particularly when integrating data from sources stored outside of AWS. For example, handling AWS Data Lakes, Delta Lake, or Hadoop file formats stored in S3 requires extensive configuration and isn't always straightforward. It would be beneficial to streamline this process to ensure smoother migrations from non-AWS environments to AWS. As for additional functionality, I think enhancing support for these external file formats and simplifying configuration steps would be valuable improvements for the service."
"It is a very expensive program and you pay a license fee based on the amount of users you have."
"This solution is compatible with only AWS. I cannot use this solution with AWS and other cloud services like Azure or Google Cloud."
"The live duplication has a delay of two minutes, which can be an issue."
 

Pricing and Cost Advice

"Licensing fees are paid on a monthly basis, and it is a pay-as-you-go model."
"The pricing can be better and it should be more competitive."
"AWS Database Migration Service is very inexpensive."
"I rate the product price a seven on a scale of one to ten, where one is a high price, and ten is a low price."
"The pricing is on the higher side."
"AWS Database Migration Service is the least expensive solution, but is still expensive."
"The pricing is per hour, though I do not have the exact figures. If you have specific questions about the service, a personal support team from Amazon is available, but this will bring in additional costs."
"Cost is the only factor that is challenging."
"Pricing can be improved."
