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.
