Amazon Elastic Compute Cloud एक अमेज़न वेब सर्विस है इस पोस्ट में हम इसके बारे में अच्छे से जानेंगे What is Amazon Elastic Compute Cloud in Hindi की Amazon Elastic Compute Cloud किसे कहते है।
What is Amazon Elastic Compute Cloud in Hindi?
Amazon Elastic Compute Cloud (Amazon EC2) provides scalable computing capacity in the Amazon Web Services (AWS) Cloud. 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. Amazon EC2 enables you to scale up or down to handle changes in requirements or spikes in popularity, reducing your need to forecast traffic.
Amazon EC2 (Elastic Compute Cloud) is a web service interface that provides resizable compute capacity in the AWS cloud. It is designed for developers to have complete control over web-scaling and computing resources.
EC2 instances can be resized and the number of instances scaled up or down as per our requirement. These instances can be launched in one or more geographical locations or regions, and Availability Zones (AZs). Each region comprises of several AZs at distinct locations, connected by low latency networks in the same region.
EC2 Components
In AWS EC2, the users must be aware about the EC2 components, their operating systems support, security measures, pricing structures, etc.
Operating System Support
Amazon EC2 supports multiple OS in which we need to pay additional licensing fees like: Red Hat Enterprise, SUSE Enterprise and Oracle Enterprise Linux, UNIX, Windows Server, etc. These OS needs to be implemented in conjunction with Amazon Virtual Private Cloud (VPC).
Security
Users have complete control over the visibility of their AWS account. In AWS EC2, the security systems allow create groups and place running instances into it as per the requirement. You can specify the groups with which other groups may communicate, as well as the groups with which IP subnets on the Internet may talk.
Pricing
AWS offers a variety of pricing options, depending on the type of resources, types of applications and database. It allows the users to configure their resources and compute the charges accordingly.
Fault tolerance
Amazon EC2 allows the users to access its resources to design fault-tolerant applications. EC2 also comprises geographic regions and isolated locations known as availability zones for fault tolerance and stability. It doesn’t share the exact locations of regional data centers for security reasons.
When the users launch an instance, they must select an AMI that’s in the same region where the instance will run. Instances are distributed across multiple availability zones to provide continuous services in failures, and Elastic IP (EIPs) addresses are used to quickly map failed instance addresses to concurrent running instances in other zones to avoid delay in services.
Migration
This service allows the users to move existing applications into EC2. It costs $80.00 per storage device and $2.49 per hour for data loading. This service suits those users having large amount of data to move.
Features of Amazon EC2
Amazon EC2 provides the following features:
- Virtual computing environments, known as instances
- Preconfigured templates for your instances, known as Amazon Machine Images (AMIs), that package the bits you need for your server (including the operating system and additional software)
- Various configurations of CPU, memory, storage, and networking capacity for your instances, known as instance types
- Secure login information for your instances using key pairs (AWS stores the public key, and you store the private key in a secure place)
- Storage volumes for temporary data that’s deleted when you stop, hibernate, or terminate your instance, known as instance store volumes
- Persistent storage volumes for your data using Amazon Elastic Block Store (Amazon EBS), known as Amazon EBS volumes
- Multiple physical locations for your resources, such as instances and Amazon EBS volumes, known as Regions and Availability Zones
- A firewall that enables you to specify the protocols, ports, and source IP ranges that can reach your instances using security groups
- Static IPv4 addresses for dynamic cloud computing, known as Elastic IP addresses
- Metadata, known as tags, that you can create and assign to your Amazon EC2 resources
- Virtual networks you can create that are logically isolated from the rest of the AWS Cloud, and that you can optionally connect to your own network, known as virtual private clouds (VPCs)
How to Use AWS EC2
Step 1 − Sign-in to AWS account and open IAM console by using the following link https://console.aws.amazon.com/iam/.
Step 2 − In the navigation Panel, create/view groups and follow the instructions.
Step 3 − Create IAM user. Choose users in the navigation pane. Then create new users and add users to the groups.
Step 4 − Create a Virtual Private Cloud using the following instructions.
- Open the Amazon VPC console by using the following link − https://console.aws.amazon.com/vpc/
- Select VPC from the navigation panel. Then select the same region in which we have created key-pair.
- Select start VPC wizard on VPC dashboard.
- Select VPC configuration page and make sure that VPC with single subnet is selected. The choose Select.
- VPC with a single public subnet page will open. Enter the VPC name in the name field and leave other configurations as default.
- Select create VPC, then select Ok.
Step 5 − Create WebServerSG security groups and add rules using the following instructions.
- On the VPC console, select Security groups in the navigation panel.
- Select create security group and fill the required details like group name, name tag, etc.
- Select your VPC ID from the menu. Then select yes, create button.
- Now a group is created. Select the edit option in the inbound rules tab to create rules.
Step 6 − Launch EC2 instance into VPC using the following instructions.
- Open EC2 console by using the following link − https://console.aws.amazon.com/ec2/
- Select launch instance option in the dashboard.
- A new page will open. Choose Instance Type and provide the configuration. Then select Next: Configure Instance Details.
- A new page will open. Select VPC from the network list. Select subnet from the subnet list and leave the other settings as default.
- Click Next until the Tag Instances page appears.
Step 7 − On the Tag Instances page, provide a tag with a name to the instances. Select Next: Configure Security Group.
Step 8 − On the Configure Security Group page, choose the Select an existing security group option. Select the WebServerSG group that we created previously, and then choose Review and Launch.
Step 9 − Check Instance details on Review Instance Launch page then click the Launch button.
Step 10 − A pop up dialog box will open. Select an existing key pair or create a new key pair. Then select the acknowledgement check box and click the Launch Instances button.
