This EC2 instance type provides a balance of compute, memory, and networking resources. You can use them for a variety of workloads.
General Purpose
This EC2 instance type is ideal for compute-bound applications that benefit from high-performance processors
Compute Optimized
This EC2 instance type is designed to deliver fast performance for workloads that process large datasets in memory
Memory Optimized
This EC2 instance type uses hardware accelerators, or coprocessors, to perform some functions more efficiently than is possible in software running on CPU
Accelerated computing
These instances are designed for workloads that require high, sequential read and write access to very large data sets on local storage. They are optimized to deliver tens of thousands of low-latency, random I/O operations per second (IOPS) to applications.
Storage Optimized
Security groups only contain this rule wise
Allow rules
Security groups are locked down to this
Region and/or VPC
This EC2 purchasing option is for short workloads, predictable pricing and pay by the second scenarios
On-Demand
This EC2 purchasing option is for 1 or 3 year terms and long workloads
Reserved & savings plans
Long duration workloads would you what type of EC2 purchasing plan
Reserved
This EC2 purchasing option is for short workloads and instances that could be lost at any time
Spot instances
This ec2 purchasing option is for EC2 hosts that wont share resources with other customers
dedicated instances
These types of instances have the most aggressive discount up to 90% compared to On-Demand.
Spot instances
These types of EC2 instances are not suitable for critical jobs or databases
Spot instances
This EC2 purchasing option is for committing to an amount of usage
Savings plan
This EC2 type has the highest cost
On-demand
The most expensive EC2 purchasing option
Dedicated hosts
