Profiler keeps an eye on your code’s performance data and helps you fine-tune your application performance. It can detect anomalies within your application and alerts if any piece of your code is creating CPU bottleneck or faces elevated latency. Moreover, it even provides visualisation and recommendations to improve your code.

Amazon Aurora Global Database supports read replica write forwarding

Aurora Global Database allows you to run multiple replicas of your database across regions. The data replication is completed across all the replicas within a second using Amazon backbone network so that your application running in multiple regions can take benefit of low latency reads. In case of a primary database failure, you can promote any of your read replicas to take the full read-write load.

Till this announcement all write queries need to be made to the primary database only but now you can send your write query to any of your read replicas and it will forward it to the primary database to commit it to the database.

Amazon FSx for Lustre now supports system backups

Amazon FSx for Lustre now supports point-in-time backup to S3. Backups are incremental in nature which means only changed data from the last backup is stored thus saving money. Moreover, you can even automate the backup schedule.
