Amazon EC2 Partition Placement Groups are Now Available in the AWS GovCloud (US) Regions

Posted on: Sep 5, 2019

Starting today, Amazon EC2 Partition Placement Groups are available in the AWS GovCloud (US) Regions.  

Partition Placement Groups are a new placement group strategy which help reduce the likelihood of correlated failures for large distributed and replicated workloads such as HDFS, HBase and Cassandra running on EC2. Partition placement groups spread EC2 instances across logical partitions and ensure that instances in different partitions do not share the same underlying hardware, thus containing the impact of hardware failure to a single partition. In addition, partition placement groups offer visibility into the partitions and allow topology aware applications to use this information to make intelligent data replication decisions, increasing data availability and durability.
