In this article, we will discuss one of the oldest, popular, and widely used AWS computing services that are EC2 – Elastic Compute Cloud. Let us understand what is EC2? Why it is one of the most important services of an AWS? What are its types? How to launch and use it? and few other characteristics.<\/p>\n

EC2 (Elastic Compute Cloud)<\/em><\/strong><\/h2>\n

Elastic Compute Cloud is a web service that provides secure, resizable compute capacity in the cloud. Designed to be IaaS (Infrastructure as a Service) it provides you with complete control of your computing resources and lets you run on Amazon\u2019s proven computing environment.<\/strong><\/em><\/p>\n

<\/figure>\n

What is unique in AWS EC2 compared to other cloud service providers IaaS?<\/p>\n

Amazon EC2 offers the broadest and deepest choice of instances, built on the latest compute, storage, and networking technologies and engineered for high performance and security.<\/p>\n

Nearly 400 instances for virtually every business need, and Only cloud provider that supports macOS, 24 regions and 77 availability zones globally, choice of Intel, AMD, and Arm-based processors, etc.<\/p>\n

Faster innovation and increased security with AWS Nitro System, Choice of processors, High-performance storage, Enhanced networking and
\nchoice of purchasing model.<\/p>\n

Let us now focus on the technical aspects of EC2 service:<\/p>\n

SLA commitment of 99.99% availability for each Amazon EC2 region. Each region consists of at least 3 availability zones (Availability Zones are known as AZ\u2019s are the logical data centers within one region).<\/em><\/p>\n

Varied instance types<\/strong><\/h2>\n

Based on the requirement such as General Purpose, Compute-optimized, Memory Optimized, Accelerated computing, and Storage optimized.<\/p>\n

General Purpose<\/em><\/strong><\/h3>\n

General-purpose instances provide a balance of compute, memory and networking resources, and can be used for a variety of diverse workloads. These instances are ideal for applications that use these resources in equal proportions such as web servers and code repositories.<\/p>\n

Variants offered in this are Mac, T4g, T3, T3a, T2, M6g, M5, M5a, M5n, M5zn, M4, and A1.<\/em><\/p>\n

Compute Optimized<\/em><\/strong><\/h3>\n

Compute Optimized instances are ideal for compute-bound applications that benefit from high-performance processors. Instances belonging to this family are well suited for batch processing workloads, media transcoding, high-performance web servers, high-performance computing (HPC), scientific modeling, dedicated gaming servers, and ad server engines, machine learning inference, and other compute-intensive applications.<\/p>\n

Variants offered in this are C6g, C6gn, C5, C5a, C5n, and C4.<\/em><\/p>\n

Memory-Optimized<\/em><\/strong><\/h3>\n

Memory-optimized instances are designed to deliver fast performance for workloads that process large data sets in memory.<\/p>\n

Variants offered in this are R6g, R5, R5a, R5b, R5n, R4, X2gd, X1e, X1, High Memory, and z1d.<\/em><\/p>\n

Accelerated Computing<\/em><\/strong><\/h3>\n

Accelerated computing instances use hardware accelerators, or co-processors, to perform functions, such as floating-point number calculations, graphics processing, or data pattern matching, more efficiently than is possible in software running on CPUs.<\/p>\n

Variants offered in this are P4, P3, P2, Inf1, G4dn, G4ad, G3, and F1.<\/em><\/p>\n

Storage Optimized<\/em><\/strong><\/h3>\n

Storage optimized 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.<\/p>\n

Variants offered in this are I3, I3en, D2, D3, D3en, and H1.<\/em><\/p>\n

Amazon EC2\u00a0pricing<\/strong><\/h2>\n

Amazon offers you different types of pricing models as per the requirement and usage in order to save cost and make the best use of computing capacity.<\/p>\n

On-Demand<\/em><\/strong><\/h3>\n

With On-Demand instances, you pay for compute capacity by the hour or the second depending on which instances you run.<\/p>\n

On-Demand instances are recommended for:<\/p>\n
