- Security. Amazon works with Amazon VPC to provide robust networking and security for the compute resources.
- Flexibility.
- Cost Saving.
- Complete Computing Solution.
- Elastic Web-Scale Computing.
- Completely controlled.
Why would you select one Amazon EC2 instance type over another?
Instance Types comprise various combinations of CPU, memory, storage, and networking capacity and give you the flexibility to choose the appropriate mix of resources for your applications. Each instance type has one or more size options that address different workload sizes.
Which type of Amazon EC2 instances should you use to reduce the backlog in the most cost efficient way?
In the question scenario, Spot Instance is the best option because its cheaper then On-Demand and, if the “process is interrupted, the video will be transcoded by another instance based on the queuing system.”
What are the three types of EC2 instances with regard to billing options?
They are: On-Demand, Reserved Instances, and Spot Instances, with the added option of Dedicated Hosts.
What is Amazon EC2 why is it used what is its purpose and benefit discuss in detail?
Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. It provides you with complete control of your computing resources and lets you run on Amazon’s proven computing environment.
What does Amazon EC2 instance type indicate?
Amazon EC2 provides a wide selection of instance types optimized to fit different use cases. Instance types comprise varying combinations of CPU, memory, storage, and networking capacity and give you the flexibility to choose the appropriate mix of resources for your applications.
What happens when an EC2 instance is terminated?
When you terminate an EC2 instance, the instance will be shutdown and the virtual machine that was provisioned for you will be permanently taken away and you will no longer be charged for instance usage. Any data that was stored locally on the instance will be lost.
What should you use to control traffic in and out of EC2 instances?
A security group acts as a virtual firewall for your EC2 instances to control incoming and outgoing traffic. Inbound rules control the incoming traffic to your instance, and outbound rules control the outgoing traffic from your instance. When you launch an instance, you can specify one or more security groups.
What is the most cost effective purchasing option for running a set of EC2 instances that must always be available for a period of two months?
Spot Instances – Spot Instances are the most cost-effective choice if you are flexible about when your applications run and if your applications can be interrupted.
How are EC2 instances billed?
Your Amazon EC2 usage is calculated by either the hour or the second based on the size of the instance, operating system, and the AWS Region where the instances are launched. Each partial instance-hour is billed as a full hour for all other instance types.
What is EC2 used for?
Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers.
How can I save money on my EC2 instances?
If you can be flexible about where your EC2 instances live, then taking the time to do some price comparisons can really pay off. Automate turning on and turning off your instances. You’ll save money if you don’t rely on doing these actions manually.
What is Amazon EC2 and why should you care?
Using Amazon EC2 eliminates your need to invest in hardware up front, so you can develop and deploy applications faster. You can use Amazon EC2 to launch as many or as few virtual servers as you need, configure security and networking, and manage storage.
How do I check if I have EC2 instances running in another region?
You terminated your instances in one Region, but you have instances running in another Region To check if you have active EC2 instances in other Regions, do the following: Open the Billing and Cost Management console. Choose Bills in the navigation pane. In the Bill details by service section, expand the Elastic Compute Cloud line item.
How to delete EC2 resources that are incurring charges?
After confirming the Regions where EC2 resources are incurring charges, do the following: 1 Open the Amazon EC2 console. 2 In the navigation bar, select the respective Region from the Region Selector. 3 Terminate or delete EC2 resources that you don’t need.
