AWS EC2 Instance Features:

Amazon EC2 instances provide a number of additional features to help you deploy, manage, and scale your applications.

  • ➢ Burstable Performance instances
  • ➢ Multiple Storage Options
  • ➢ EBS Optimized Instances
  • ➢ Cluster Networking

Burstable Performance Instances:
Amazon EC2 allows you to choose between Fixed Performance
Instances (e.g. M5, C5, and R5) and Burstable Performance Instances (e.g. T3). Burstable Performance Instances provide a baseline level of CPU performance with the ability to burst above the baseline.

For example, a t2.small instance receives credits continuously at a rate of 12 CPU Credits per hour. This capability provides baseline performance equivalent to 20% of a CPU core (20% x 60 mins = 12 mins). If the instance does not use the credits it receives, they are stored in its CPU Credit balance up to a maximum of 288 CPU Credits. When the t2.small instance needs to burst to more than 20% of a core, it draws from its CPU Credit balance to handle this surge automatically.

Multiple Storage Options: Amazon EC2 allows you to choose between multiple storage options based on your requirements. Amazon EBS is a durable, block-level storage volume that you can attach to a
single, running Amazon EC2 instance. Amazon EBS provides three volume types to best meet the needs of your workloads: General Purpose (SSD), Provisioned IOPS (SSD), and Magnetic.5

EBS Optimized instances: For an additional, low, hourly fee, customers can launch selected Amazon EC2 instances types as EBS-optimized instances. For M6g, M5, M4, C6g, C5, C4, R6g, P3, P2, G3, and D2 instances, this feature is enabled by default at no additional cost. EBS-optimized instances enable EC2 instances to fully use the IOPS provisioned on an EBS volume. EBS-optimized instances deliver dedicated throughput between Amazon EC2 and Amazon EBS, with options between 500 and 4,000 Megabits per second (Mbps) depending on the instance type used.

Cluster Networking: Select EC2 instances support cluster networking when launched into a common cluster placement group. A cluster placement group provides low-latency networking between all instances in the cluster. The bandwidth an EC2 instance can utilize depends on the instance type and its networking performance specification.
