False Your company has deployed their production environment on AWS and now need to access this via a bastion host using Windows Remote Desktop protocol. A spread placement group can span multiple Availability Zones in the same Region. With spread placement groups, each instance is placed in separate rack spanning multiple Availability Zones. In general, proximity placement groups can be used in any scenarios where low latency is desirable. By defining node pools in a cluster to span multiple zones, nodes in a given node pool are able to continue operating even if a single zone has gone down. The number of instances that can be launched into a partition placement group is limited only by the limits of your account. AKS clusters deployed with multiple availability zones configured across a cluster provide a higher level of availability to protect against a hardware failure or a planned maintenance event. While a PPG can’t span zones, this combination is useful in cases where you care about latency within the zone like in a case of an active-standby deployment where each is in a separate zone. A.) It could be as simple as two standalone VMs that need to communicate with each other. Business-critical applications can now be hosted with confidence on the cloud. partition --> max of 7 partitions per AZ per group. Region specific Auto Scaling groups allow you to spread compute resources across multiple Availability Zones, which help applications be resilient to zone specific maintenance. group of instances spread across racks. Placement Groups can be created across 2 or more Availability Zones. It could also be a complex multi-tier application with VMs deployed in multiple availability sets or VMs deployed in different scale sets. You can use a proximity placement group alongside availability zone. A partition placement group can have a maximum of seven partitions per Availability Zone. Partitions are logical groupings of instances, where contained instances do not share the same underlying hardware across different partitions. You can have a maximum of seven running instances per Availability Zone per group. Applications deployed across multiple availability zones or regions can expect increased availability and fault tolerance when compared to running in one zone or region. A spread placement group can span multiple Availability Zones in the same Region. EC2 divides each group into logical segments called partitions. On the other hand, placement groups are created implicitly when you create a scale set. An Availability Set allows you to take a Virtual Machine (VM) and improve it’s availability by configuring multiple copies of the VM to be deployed as a group which ensures that the Azure management plane will place the VMs such that the hosted workload(s) are resilient across Azure updates and faults. An ASG spread across multiple AZs can still take advantage of the cluster autoscaler as well as any auto scaling trigger AWS provides . This HA architecture is suitable in cases where the application is made up of a small number of critical instances and hence it is ideal to deploy them across multiple racks for high availability. Spread placement groups require a name that is unique within your AWS account for the region B.) Partition Placement Groups. The difference is in how each may be used. is a group of instances spread across partitions i.e. Availability sets are used with VMs and cannot be used with availability zones. Scale sets allow for greater scale by deploying across multiple placement groups and even across multiple availability zones. How each may be used with availability Zones in the same Region instance is placed separate. And fault tolerance when compared to running in one Zone or Region applications.
