Accelerated computing instances offer GPU co-processors that make them much better for these types of workloads.
Accelerated Computing: Some types of calculations, such as graphics processing or machine learning algorithms, are better run on GPUs than on CPUs.Memory Optimized: These instances offer a higher memory to CPU ratio than general purpose instances, making them the best choice for workloads that don't consume a lot of CPU, but need a high amount of memory, such as caches and databases.The latest families are c7g (with Graviton3 processors) and c6i (with Intel processors). Compute Optimized: These types of instance have a higher CPU to memory ratio, which makes them suitable for workloads that are compute-intensive.The most common general purpose instance types are m7i powered by Intel processors, m7g powered by AWS's proprietary Graviton3 processors (ARM-based), and t4g, which are burstable instances that accumulate credits when CPU usage is low and then consume them to increase performance. General Purpose: As the name suggests, these are jack-of-all-trades instances suitable for a wide range of workloads.Each EC2 instance runs in one AZ, and if you're running several EC2 instances they can be spread across multiple AZs for high availability.ĮC2 offers different instance families and types, to better suit different workload requirements: Each region has multiple isolated locations known as Availability Zones (AZs). Regions and Availability Zones: AWS infrastructure is spread worldwide and divided into regions.This flexibility in size lets you deploy only the resources you actually need, without overprovisioning. For example, you could run an m7i.large instance with 2 vCPUs and 8 GBs of memory, or an m7i.xlarge with 4 vCPUs and 16 GBs of memory. Instance Sizes: Even within the same type, EC2 instances can come in different sizes.With this variety, you can launch the instance type that better suits your workload, and only pay for what you actually need. For example, you can deploy general purpose instances, or instances with a higher memory to CPU ratio, or instances with GPUs for graphics processing or artificial intelligence models. EC2 offers an array of instance types, with different configurations for CPU, memory, GPUs, network and storage. Instance Types: Not all EC2 instances are equal, or equally priced.You can also create your own AMIs, which can contain your application already installed and configured. It acts as a template containing the OS, software, libraries, and configurations. Amazon Machine Images (AMIs): When you're creating an instance, you select an AMI, which is a pre-configured package required to boot up the instance.There are a few additional features that are part of EC2, and that will let you do more than just run a single server:

Then you're free to use it however you want, including installing software, hosting applications, serving content or running any kind of process. You can launch an instance whenever you need it, and it'll be available in less than a minute. The most important component of EC2 are instances, which are essentially virtual servers in AWS's infrastructure.
With EC2 you can launch your cloud infrastructure with just a few clicks, scale it when needed, and reduce capacity during off hours while only paying for the instances you're actually running. It offers virtual machines called EC2 instances, which are readily available in minutes and are billed only when they're active. Amazon Elastic Compute Cloud (EC2) is the core compute service of AWS.
