Amazon Web Services (AWS) Elastic Compute Cloud (EC2) is a web-based service that provides a scalable, virtualized computing solution. EC2 is a part of the broader Amazon Web Services (AWS) platform and allows users to rent virtual computers on which to run their own applications. AWS EC2 instances are designed to allow users to choose the right instance type for their specific application and workload requirements.
The AWS EC2 instance types are designed to allow users to choose the right instance type for their specific application and workload requirements. This blog post will provide an overview of the different EC2 instance types, their features, and use cases in detail.
Overview of AWS EC2 Instance Types
AWS EC2 instance types are virtual machines that are designed for specific workloads. They come in a variety of sizes, from tiny to large, and are optimized for specific computing, memory, storage, and networking needs.
AWS EC2 instance types are divided into five categories: General Purpose, Compute Optimized, Memory Optimized, Storage Optimized, and Accelerated Computing. Each of these categories has its own set of instance types, each optimized for different workloads.
1. General Purpose Instances
General-purpose instances are designed for a broad selection of workloads. They are ideal for web and application servers, small to medium-sized databases, and development and test environments.
The general purpose instance types include the following:
- T2 – A low-cost, general-purpose instance type that provides a baseline level of CPU performance and is ideal for web servers, small databases, and development environments.
- M4 – A general-purpose instance type that provides increased compute power and memory compared to the T2 instance type. Ideal for web and application servers, medium-sized databases, and development environments.
- M5 – A general-purpose instance type that provides increased compute power and memory compared to the M4 instance type. Ideal for web and application servers, large databases, and development environments.
2. Compute Optimized Instances
Compute-optimized instances are designed to provide the highest performance for compute-intensive applications. They are ideal for high-performance computing, distributed analytics, batch processing, media transcoding, and scientific modeling.
The compute-optimized instance types include the following:
- C4 – A high-performance instance type that provides increased compute power compared to the M4 instance. Ideal for distributed analytics, batch processing, and media transcoding.
- C5 – A high-performance instance type that provides increased compute power compared to M5. Ideal for high-performance computing, distributed analytics, and scientific modeling.
3. Memory Optimized Instances
Memory-optimized instances are designed to provide the highest performance for memory-intensive applications. They are ideal for in-memory databases, distributed caching, and Big Data analytics.
The memory-optimized instance types include the following:
- R4 – A fast, memory-optimized instance type that provides increased memory compared to the M4 instance type. Ideal for in-memory databases and distributed caching.
- X1 – A memory-optimized instance type that provides increased memory and computes power compared to the R4 instance type. Ideal for in-memory databases and Big Data analytics.
4. Storage Optimized Instances
Storage-optimized instances are designed to provide the highest performance for storage-intensive applications. They are ideal for distributed NoSQL databases, Hadoop, and data warehousing. The storage-optimized instance types include the following:
- I3 – A fast, storage-optimized instance type that provides increased storage compared to the M4 instance type. Ideal for distributed NoSQL databases, Hadoop, and data warehousing.
- D2 – A storage-optimized instance type that provides increased storage and computes power compared to the I3 instance type. Ideal for distributed NoSQL databases, Hadoop, and data warehousing.
5. Accelerated Computing Instances
Accelerated computing instances are designed to provide the highest performance for graphics-intensive applications. They are ideal for machine learning, high-performance computing, and data science. The accelerated computing instance types include the following:
- P2 – A fast, GPU-accelerated instance type that provides increased compute power compared to the M4 instance type. Ideal for machine learning, high-performance computing, and data science.
- G3 – A GPU-accelerated instance type that provides increased compute power and memory compared to the P2 instance type. Ideal for machine learning, high-performance computing, and data science.
Here are some of the key factors you need to consider when choosing an EC2 instance type
- Compute: The amount of CPU and memory resources available to an instance is critical to the performance of your application.
- Storage: The amount of storage and I/O performance required by your workload will affect the instance type you choose.
- Network performance: Network performance is a critical factor for many workloads, such as databases, web applications, and data transfer.
- Cost: EC2 instances are priced based on the resources they provide, such as CPU, memory, storage, and network performance.
