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.

Good management and pricing but not great for enterprise environments
In a high-density location, we're running into connectivity drops. There may be too many rouge devices broadcasting, and the devices is getting interference from another channel. The only to fix this is to reboot and we need something that reboots on the fly. We also need better security for VLANs and VPNs. There are issues with certain Apple devices. Technical support is not very helpful. The initial setup, which seemed straightforward at first, had to be redone. This may not have been the fault of the product. We're not sure what went wrong.

Quotes from Members

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

Pros

"If your infrastructure is already on Amazon, it simply makes the most sense to use a tool officially provided by them as an additional service, rather than having to rely on a third-party solution."
"Scalable and stable solution for migrating databases to AWS, with valuable features such as parallel full load and continuous data replication."
"The most valuable feature of AWS Database Migration Service is it catches all the history changes, such as inset, observe, and delete. It tracks everything."
"The solution makes it very simple to migrate the database."
"I like that I can focus on the logic and I don't have to worry about the administration stuff. AWS handles that for me."
"The way it works is brilliant, and it's based on similar logic to Oracle's GoldenGate migration tool in that you can migrate everything from data tables to schemas from one database to another."
"This solution is very good at mini-batch processing."
"The most valuable features of the AWS Database Migration Service are the ease of migration, beneficial storage system, security, and simple instance creation. Additionally, the cloud that is provided is more complete than other solutions."
"The controller makes it easy to control everything from one platform. The management is easy."
"It's easy to manage and supports the user, our guests, and our customers if they have a problem."
 

Cons

"The technical support for AWS Database Migration Service is bad. They are still figuring out how to support their product."
"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."
"One drawback I experienced was with balance and sync."
"One area that AWS DMS can improve on is its conversion of data types. For example, in Oracle, you have a data type called RAW, but in PostgreSQL there is no such thing. Thus, AWS DMS doesn't know what type I want to use when migrating from Oracle to PostgreSQL, and when performing the migration, AWS DMS changed the RAW data type to the byte data type, which isn't what I wanted."
"Improvements could be made in AWS Database Migration Service. Because of that, I am moving out of DMS now to a STRIIM solution."
"The solution’s scalability and performance could be improved."
"The product's performance could be a little bit better."
"I only used AWS DMS over the course of about three months, but I could tell that it's not always stable."
"There are issues with certain Apple devices."
"It's stable, but it depends on the office and location."
 

Pricing and Cost Advice

"For Egypt, the product's prices are high, making it a specific problem in one region and not globally."
"In terms of pricing, I'd rate it an eight out of ten, considering it's a well-priced solution."
"The pricing is on the higher side."
"Pricing for the solution is reasonable, but could still be reduced."
"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."
"AWS Database Migration Service is very inexpensive."
"Cost is the only factor that is challenging."
"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."
"There is no license. The solution is free."
