ec2 in cloud computing

Within the enormous field of cloud computing, Amazon Web Services (AWS) stands out as a pioneer, offering a myriad of services that empower businesses to scale and innovate. Among these services, Elastic Compute Cloud (EC2) takes center stage, providing resizable compute capacity in the cloud.

What is EC2?

EC2, an acronym for Elastic Compute Cloud, is a web service that delivers secure, resizable, and on-demand compute capacity in the cloud. It allows users to launch and manage virtual machines, known as instances, on Amazon’s vast infrastructure. These instances provide the same functionality as physical servers, but with the added flexibility and convenience of the cloud.

How does EC2 work?

For compute capacity, EC2 offers virtual servers, sometimes referred to as instances. To meet their needs, users can select the memory size, power, number of instances, and size.

Additionally, to assist with traffic management and application availability maintenance, EC2 provides features like load balancing and auto-scaling. It gives programmers the resources they need to create applications that are resistant to failure and keeps them separate from typical failure scenarios.

Types of EC2 Instances

EC2 offers a diverse range of instance types, each tailored to specific workloads and performance requirements. These instances are categorized based on their CPU, memory, storage, and networking capabilities. The most common instance types include:

• General Purpose (T2, T3): Ideal for web applications, development environments, and light workloads.
• Compute Optimized (C4, C5): Designed for compute-intensive applications, such as high-performance computing (HPC) and machine learning.
• Memory Optimized (R3, R5): Suitable for memory-intensive workloads, such as in-memory databases and data analytics.
• Storage Optimized (D2, D3): Optimized for storage-intensive applications, such as large data repositories and content delivery networks (CDNs).
• Accelerated Computing (G2, P4): Equipped with specialized hardware accelerators, such as GPUs and FPGAs, for graphics-intensive applications and machine learning.
