Benefit from Ongoing Innovation with Google Cloud. Over the years you might have worked with either AWS or Azure as cloud providers, both offer fairly similar services, so the experience in one of them mildly translates into the other one, as long as you know the basics. Be aware that for Aurora, there is a limitation for the T2 instances such that Performance Schema can cause the host to run out of memory if enabled. Microservices and other approaches are often paired with Kubernetes, and anytime we stumble over a rough area, it can be easy to just blame Kubernetes for the issue. Excellent comparison. I think there are a couple reasons why there is a trend towards teams not choosing DC/OS for containers: 1. Sources: DB Cluster Configurations. For both products, Amazon applies required updates and the latest patches without any downtime. For RDS MySQL you have to select the type and size for the EBS volume, and you have to be sure that provisioned EBS IOPs can be supported by your instance type as EBS IOPs are restricted by the instance type capabilities. For RDS MySQL, storage costs are based on the EBS type and size. By choosing Amazon Aurora you are fully dependent on Amazon for bug fixes or upgrades, If you need to use MySQL plugins you should use RDS MySQL, Aurora only supports InnoDB.

The architecture used and the way that replication works on both products shows a really significant difference between them. You should use AKS if you need full container orchestration, such as service discovery across multiple containers, automatic scaling, and coordinated application upgrades. What Is Airflow? For example, due to the need to disable the InnoDB change buffer for Aurora (this is one of the keys for the distributed storage engine), and that updates to secondary indexes must be write-through, there is a big performance penalty in workloads where heavy writes that update secondary indexes are performed. Migration to RDS can be performed using Percona XtraBackup.
