Among the most popular AWS services is Amazon EC2, precisely because it offers companies scalable computing capacity in the Amazon Web Services cloud. And the key to the operation of this service is the instances (virtual machines) that make it up.


“Instance types span various combinations of CPU, memory, storage, and networking capacity. They give you the flexibility to choose the right combination of resources for your applications. Each instance type includes one or more instance sizes, allowing you to scale your resources based on the requirements of your target workload", explained about it in the AWS documentation.


How the Amazon EC2 storage system works


All the operations that Amazon EC2 executes are thanks to Amazon Elastic Block Store (Amazon EBS), it is a scalable block storage service that adjusts to all kinds of operations and companies.

  • It allows scaling those workloads that are more complex and demanding.
  • There is 99% availability of the system, so errors will be minimal.
  • The company can select the type of storage that fits its workload.


Amazon EBS volume types: gp2 vs gp3


gp2 and gp3 are two of the most used types of SSD volumes today. And here we will talk about the characteristics of each one so that you can see which one is best for your project or company.
