Amazon EC2 instance
What is an Amazon EC2 instance?
A virtual server on Amazon’s Elastic Compute Cloud (EC2) for running applications on the Amazon Web Services (AWS) infrastructure is known as an Amazon EC2 instance. AWS is a complete cloud computing platform that is constantly expanding; EC2 is a service that allows corporate subscribers to run application programs in a computing environment. It can also be used to create an almost infinite number of virtual machines (VMs).
To meet user needs, Amazon offers a wide range of instances with diverse CPU, memory, storage, and networking resource combinations. Each type is offered in a variety of sizes to meet the diverse needs workloads.
EC2 instance types
Instance types are grouped into families based on target application profiles. These groups include the following:
· General purpose. A general-purpose instance is a virtual machine that can manage a wide range of tasks. The number of CPU cores, on-demand storage, and memory in general purpose instances are optimized. Web server hosting and software development and testing are two common use cases for general purpose instances.
· Compute optimized. On the AWS cloud, compute optimized instances are used to execute big data applications that require a lot of processing power and memory. These instances are structured and tuned to run computational and data-intensive applications that demand high input/output (I/O) operations per second, high network performance, and high availability (IOPS). Scientific and financial modeling and simulation, machine learning, enterprise data warehousing, and business intelligence are examples of sorts of applications.
· Graphics processing unit (GPU). These instances make it possible to run graphics-intensive applications more quickly than normal EC2 instances. Gaming and design work are two examples of systems that use GPUs. GPUs are frequently used in Linux distributions to render graphical user interfaces, improve compression speeds, and speed up database queries, for example.
· Memory optimized. A high-speed solid-state drive is used in memory optimized instances to enable ultra-fast data access and great performance. Open source databases, real-time big data analytics, and in-memory caches are all good candidates for these instances, which demand more memory and less CPU power.
· Storage optimized. Applications that demand high I/O speed, such as NoSQL databases that save and retrieve data in real time, benefit from storage optimized instances. They’re also ideal for memory-intensive activities including data processing, data warehousing, analytics, and log processing.
· Micro. A micro instance is designed for low-throughput applications. Micro instances can be used as a small database server, a platform for software testing, or a web server that doesn’t require a lot of traffic.
