The CloudWatch service allows for the monitoring of AWS cloud services and applications deployed on AWS. It is used to collect, store, and analyze historical and real-time performance data. This helps in the case of failover clusters, for load balancing, or for other purposes where multiple servers run at the same time.ĮC2 instance supports several OSes such as Linux, Microsoft Windows Server, CentOS and Debian. It can be moved from instance to instance without requiring a network administrator’s help. Below are some of the features of the Amazon EC2 instance: Many of the Amazon instances features are customizable such as storage, virtual processor, memory available to instances, etc. ![]() Storage-optimized instances are designed for workloads that contain very large data sets which has to be written in memory and require high, sequential read and write access.ĭo you want to read about AWS from scratch? Read this blog on ‘ what is AWS ‘? G3 is for graphic-intensive applications. P3, P2, G3, and F1 are instances for accelerated computing. These instances are the latest gen general-purpose instances, and they provide an accelerated performance when the CPU clock rate increases. Learn AWS from experts, click here to know more about AWS Online Training Accelerated Computing Instances R4, R5, R5a, and R5d instances are memory optimized. These instances are for delivering fast performance for processing large data sets in memory. Dedicated gaming servers and ad serving enginesĬ5, C4, and C5n are the instances under this category.Īre you looking for AWS training in Bangalore ? Memory-optimized Instances.They are well suited for the following applications: These instances are useful for compute-dependent applications that need high-performance processors. Moving on, let’s now see different types of Amazon EC2 Instance Types.Īre you preparing for an AWS interview? Then here are the latest AWS interview questions AWS EC2 Instance TypesĪWS EC2 instance types determine the underlying hardware of the instances which are launched. Elasticity is the feature from which Elastic Compute Cloud got its name. Instead of 10 low-configuration machines, you could rent a single high-configuration machine with an OS of your preferred choice for your application. You can always store multiple copies of your application in multiple AZs so that when one data center fails or loses data, the application will not fail completely. Also, this will increase the load speed of your application around the world. ![]() So, it only has to pay for 50 servers those days, not the usual fee for the usage of 100 servers.Įven when you use your Amazon EC2 instances services for a few hours, you only need to pay for that time period and nothing more.ĪWS is spread across 20 worldwide regions with 61 availability zones (AZs) which helps your business when it is expanding. A company, XYZ might be using 100 servers normally, and on Mondays, it scales down to 50 servers. ![]() You will be charged by the hour, and you have to pay only for what you have used. If you have any doubts or queries related to AWS, post them on AWS Community. They either scale up or scale down corresponding to the increase or decrease in demand. It is already explained earlier how Netflix uses Amazon EC2 auto-scaling to its advantage and provides a crash-free experience.Īuto-scaling is basically providing resources according to the demand. This is the benefit that makes most businesses opt for AWS EC2. The word ‘elastic’ in Elastic Compute Cloud talks about the system’s capability of adapting to varying workloads and provisioning or de-provisioning resources according to the demand. Also, you can scale up or down when there is an increase or decrease in website traffic. You can use EC2 in AWS to launch as many virtual servers as you need. It enables you to build and run applications faster. EC2 enables on-demand, scalable computing capacity in the AWS cloud.Īmazon EC2 instances eliminate the up-front investment for hardware, and there is no need to maintain any rented hardware. You can run multiple virtual computers in a single physical hardware.Įlastic Compute Cloud (EC2) is one of the integral parts of the AWS ecosystem. But the difference is that it is totally virtualized. Well, to be very simple, EC2 is a machine with an operating system and hardware components of your choice. Amazon EC2 is one of the most used and most basic services on Amazon so it makes sense to start with EC2 when you are new to AWS. The full form of Amazon EC2 is Amazon Elastic Compute Cloud.
