Amazon EC2 – Secure and Resizable Compute Capacity in Cloud

Amazon Elastic Compute Cloud (Amazon EC2) is a virtual server through which one can prepare an environment where you can immediately run virtual servers of various OS such as Linux, Windows, Red Hat etc.  Provide in the cloud computing capacity capable of changing size. Since the size of the computing processing capacity in the cloud can be changed, the user can secure flexible scalability in application development.

Benefits of Amazon EC2

Server procurement speed – Usually for days from several days to several weeks for a physical server, EC2 can be prepared in a few seconds.

Location – EC 2 can also be launched immediately to the overseas data center (called the region) owned by AWS. For example, you can immediately prepare 10 servers in India, 10 in the United Kingdom and 10 servers in the United States.

Can copy server environment – EC2 can make the setting information and data into a format like AMI, and you can build a new EC 2 from that AMI. For example, it is easy to copy a server from a development environment to a production environment.

Redundancy – It is very easy to make the data center redundant.

Flexible change in specifications & increase/decrease in the number of servers – One can increase the capacity of the disk. Specification change is possible in a few minutes. You can also increase or decrease the number of units. There are functions such as “auto scale” which can change the number automatically. You can also flexibly add disk capacity.

Inexpensive – Amazon EC2 passes on to you the financial benefits of Amazon’s scale.

Easy To Start – There are multiple ways to get started with Amazon EC2. One can use AWS Command Line Tools (CLI), AWS – Management Console or AWS SDKs.

Integrated – Amazon EC2 is integrated with most AWS services such as Amazon Relational Database Service (Amazon RDS), Amazon Virtual Private Cloud (Amazon VPC) and Amazon Simple Storage Service (Amazon S3).

How to Use Amazon EC2

First of all, prepare the image of the virtual machine, but since there are Amazon prepared in advance, you can also use it, designate the image and launch the virtual machine instance in EC2. Instance Since the key of SSH registered is registered, one can log in as root and use it as they like. However, stopping the instance will cause the disk image to disappear, so one must write the data to external storage (such as Amazon S3) with own responsibility.

Availability Zone

EC 2 has the concept of Region and Availability Zone (AZ) Region is a geographically isolated place, the AZ points to the section in each Region and is divided so as not to fail at the same time. If you designate that you host your computer in the AZ’s, you get more robustness.

Use of Amazon EC2

EC2 will be effective if the necessity of the computer will fluctuate greatly depending on the time, for example, payroll accounting only occurs around the closing day. The cost of tax calculation and corporate accounting can be taken considerably for holding a computer. When considering this area, even if it is expensive, there may be a solution that always uses EC2.

What is Amazon EC2 Rescue?

Amazon EC2 Rescue is a convenient and easy GUI based troubleshooting tool that runs on Amazon EC2 Windows Server instances. This can be used to troubleshoot operating system level problems and can also be used to gather and analyze detailed logs and configuration files.
