Cost Effective and Fully Cloud Managed Relational Database Service
Commentaires : Had A Really Great Experience with RDS, I have been evaluating Aurora with Native RDS so i will be talking more about Aurora in this Review
RDS provides support for verity of database systems like mysql, postgreSql, Maria DB, Oracle, Microsoft Sql and a hybrid Aurora (supports both mysql & psql) Resizing, network management processes like subnet and security group are easily manageable. Using Aurora it has become easy to transfer data from DB to S3 using "INTO OUTFILE S3" query Aurora is really faster when it comes to executing heavy flock of query simultaneously when compared with its native RDS, it increases the over all through put Aurora Server less is a extremely cost effective solution when used with proper configurations, it scales up and scales down as per its usage (pay per sec) Supports Auto Backing up and scheduled snapshotting which stores the DB snapshot in S3, which helps in recovery at times of data deleted by mistake or data corruption by some failure in the application etc Aurora provides Export Snapshot to S3 feature, its a additional feature towards data movement from RDS to S3, from this we can easily migrate data from RDS to Redshift or Athena via S3
Can't change subnet of a multi AZ RDS Database directly, to achieve this i had to first change my DB to single AZ Aurora Server less dose not scale up when used with low CPU utilising application, user should have given the flexibility to change the autoscaling parameter for Aurora server less (CPU utilisation 70%) Aurora the use of "INTO OUTFILE S3" query requires some additional setup steps at the s3 bucket end and IAM role which is well documented, but quite confusing, Aurora dose not support newer mysql or psql versions which are supported by its native RDS's Aurora when compared with its native RDS its slower for executing single queries, officers Aurora is really faster when it comes to executing heavy flock of query simultaneously, but at the least we expect Aurora to perform as the same level as its native RDS when it comes to single queries Aurora's Export Snapshot to S3 feature only supports Parquet file format, and on trigging Export it takes more time to start, it wold be better if the process starts instantaneously

High availability even for database beginners
Commentaires : I am using it as a MySQL server. With a managed database server, almost everything can be configured by just operating the configuration screen, so it is recommended that even members with little knowledge of MySQL can create a high availability database infrastructure, such as creating a Master-Slave configuration. It was possible to significantly reduce the man-hours required to install and configure the DB supports in EC2 and the upgrade procedure for maintenance, and dedicate the man-hours to other design and construction work. Including a BD license, it has freed us from license management. In addition, by not needing a physical space, we are freed from the whole flow of purchasing it.
It is a pay-per-use system where you are only charged for the number of transactions that occur. Still, there is also a subscription system called Reserved Instances (RI), so instances that generate transactions frequently use this system to reduce costs significantly. There are three types to choose from: one-year prepayment, one-year prepayment, monthly payment, and no prepayment, depending on the kind of discount. Pay-per-use is basically cheaper for cases where transactions do not occur frequently, depending on the situation, so you can optimize the charge by using different payment methods depending on the application.
I would like you to provide a concrete fault test solution. If you do not have a high level of knowledge about RDS, you cannot be relieved that you cannot perform useful failure tests assuming a failure occurs.
Amazon RDS - All Your Databases at same place
Commentaires : Great!
Amazon RDS provides the capability to host whichever database server customer wants, providing options like MS SQL , PostgreSQL, and have its own in house Aurora DB.With the Host and user/password simplified model like any other database it allows users who are not familiar with cloud to use it similarly.I have used Amazon RDS with all kind of databases and the way it optimizes costs and provides integration to logs is amazing.
Log and monitoring on the console could be improved and enhanced heavily

Will cost you all yourmoney.
Easy to setup. Very expensive. Play great with other AWS services.
The main issue is that metrics collected manually will never meet AWS metrics which are used to bill your stack. And of course AWS point of view will be much costly. Their Enterprise Support can not understand why metrics extracted from DB itself do not meet billing metrics and will endlessly redirect you to yet another expert.
Requires minimum knowledge or time to set up the database. Everything you need is basically there. Documentation is fantastic. It just works and takes all the burden of infrastructure management from you. A handful of engines, version, and extensions to them are supprted. Integrated seamless to AWS infrastructure.
Price. It will literally eat 7/8 of your infrastructure budget. Metrics lies. Performance insight simply does not work. Note, this is an opinion of somebody who paid for AWS Enterprise support (sigh, that's me) Backups are not backups per se, this is filesystem rsync. So it is easy to end up with broken DB. Support is very poor.

Dependable Database management solution
Commentaires : Overall it has amazing control features and i have never experienced any kind of downtime with them, they also have very enhanced security features so data birch is out of the question.
I is easy to integrate and implement also the customer support is quite good when one is having problems with any of their features.Its also important to note that the backup and recovery are free if you turn on the automation feature
Auto backup is not automatically turned on so if one forgets to turn it on this might cause challenges in the long run, also i don't think its right even after paying for the solution upfront that one has to leave their financial information on the system
