What Is Amazon EC2? — Amazon Elastic Compute Cloud
Amazon EC2
Amazon Elastic Compute Cloud (Amazon EC2) provides scalable computing power in the Amazon Web Services (AWS) cloud. Using Amazon EC2 eliminates the need to invest in hardware in advance, so you can develop and deploy applications quickly. You can use Amazon EC2 to start as many virtual servers as you need, configure security and networking, and manage storage. Amazon EC2 allows you to scale up or down to address changes in requirements or popularity peaks, reducing the need to predict traffic.

Component EC2
In EC2 AWS, the user must be aware of EC2 components that support the operating system, size of Security, surgery, etc.
Operating system support
Amazon EC2 supports multiple operating systems you have to pay additional licenses such as Red Hat Enterprise, SUSE and Ubuntu trading companies Oracle Linux, UNIX, Windows Server, OS etc. The task must be done in conjunction with the Amazon Virtual Private Cloud (VPC).
Security
Users have full control over the visibility of their AWS account. In AWS EC2, security systems allow the group to run the agency according to the requirement. You can determine the group with the other groups can communicate, and the group with IP subnets on the Internet can talk.
Pricing
AWS offers a variety of surgical options, depending on the type of feature, application type, and database. This allows the user to configure the features and calculate their costs accordingly.
Fault tolerance
Amazon EC2 allows users to access features in designing fault-tolerant applications. EC2 also contains the geographical location and known availability of the isolated area for fault tolerance and stability. Do not share the security concerns of the exact location of the regional data center.
If the user performs an example, he must choose one of the IAMs in the same area in which the samples are to be run. Agencies are spread across various availability zones to provide continuous service in failure, and elastic IP address (CIE) used to assign quickly managed to solve an example of establishments along the road in other areas not delayed services.
Migration
This service allows the user to move applications on EC2. Its price is $ 80 for tool storage and $ 2.49 per hour for data loading. These services that correspond to users have a lot of data to transfer.
Feature on Amazon EC2
Amazon EC2 provides the following features:
• virtual computing environments, known as agencies
• Pre-configured templates for your agency, known as Amazon Machine Images (AMIs), the bite package you need for your server (including the operating system and additional software)
• Variety of CPU configuration, memory, storage and network capacity for the agency, known as type examples
• secure access information for the agency to use a pair of keys (AWS puts the public and the private key is kept in a safe place)
• Data storage volumes to be temporarily removed when your sample is stopped or terminated, known volumes from the sample store
• Persistent storage volumes for data used by the Amazon Elastic Block Store (Amazon EBS), known as Amazon EBS volumes
• various physical locations for the phone, such as Amazon EBS agencies and volumes, known as regions and availability zones
• A firewall that allows you to specify the IP protocol, port, and source can reach the body using security groups
• Static IPv4 addresses for dynamic cloud computing, called elastic IP addresses
• Metadata, known as tag, that you can create and allocate resources for Amazon EC2
• Virtual network can create a logical mind for the rest of the AWS cloud, and optionally can be connected to the network itself, known as a virtual private cloud (VPC)
