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.

Centralizing database tables enhances workflow efficiency for ease of use
I was looking for some content as part of a comparison analysis. However, one of the pain points is that it is way too free-flowing. I have to skim through all the security pages to get to the crux of it. I was looking for a table that suggests which facets such services address with proofs of reference from professional conferences. The document is a 63-page read, making it very difficult to navigate without a summary. I was looking for a summary at the start, however, if I have to do it myself, I might as well integrate from AWS Docs and then Informative Exchange. The current document contains a lot of information, which is great, but there needs to be a summary indicating the story's essence. Unless there's a correction, it is not present in the document.

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."
"AWS has made it easy for developers like me to create and manage GraphQL APIs."
"What I like about AWS Database Migration Service is that it's a good product that allows you to migrate terabytes of data. My team was able to migrate almost 16TB of data using AWS Database Migration Service. The solution works fine for my use case."
"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."
"It's pretty useful when we need to migrate something big from a different type of database that AWS Data Migration Services supports."
"Support is helpful."
"The initial setup is very straightforward."
"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 tools are very user-friendly."
"It's scalable."
 

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."
"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."
"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."
"Sometimes we encounter errors, and the error messages from DMS are very ambiguous and sometimes misleading."
"The initial setup can be difficult for beginners in AWS Database Migration Service. You will need the training to complete it."
"If they had some sort of functionality where, at a specific point in time, if I want to start a new job, it should automatically pick up from where it has been left rather than having people worry about the exact job number and the timing."
"Migrating from here and pushing the data from on-premise to AWS cloud is a big challenge and a few more services from AWS would be helpful. For example, we are currently using ILDB internet tools which move data from on-premise to the AWS cloud. A few more services would be really helpful for me to move the master data."
"The live duplication has a delay of two minutes, which can be an issue."
"This solution can offer more tweaks where the latency can be brought down to fifteen seconds."
"The product's performance could be a little bit better."
 

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."
"Cost is the only factor that is challenging."
"The solution’s pricing is reasonable."
"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 the least expensive solution, but is still expensive."
"Pricing can be improved."
