By Jayant Sharma Creating a VPC Step 1  − Open the Amazon VPC console Step 2  − Click on the start VPC wizard/Launch VPC wizard option: Step 3  − Click on VPC with single public subnet option on the left side: In this, your instances run in a private, isolated section of the AWS cloud with direct access to the Internet.   You can choose the second option also i.e. VPC with public and private subnets where i n addition to containing a public subnet, this configuration adds a private subnet whose instances are not addressable from the Internet. Instances in the private subnet can establish outbound connections to the Internet via the public subnet using Network Address Translation (NAT). Step 4  − A configuration page will open. Fill in the details like VPC name, subnet name and leave the other fields as default. Click the Create VPC button: Here, enter any VPC name and click on create VPC button. Go to You...

By Jayant Sharma Introduction Amazon VPC a llows the users to use AWS resources in a virtual network. It   enables you to launch AWS resources into a virtual network that is defined you .  It is logically isolated  from other virtual networks in the AWS Cloud.  The users can customize their virtual networking environment as they like, such as selecting own IP address range, creating subnets, and configuring route tables and network gateways.  VPC also enables a developer to create security groups to set limits on inbound and outbound traffic to AWS EC2 instances. A subnet is a logical partition of an IP network into multiple, smaller network segments.  The practice of dividing a network into two or more networks is called  subnetting.  It is typically used to subdivide large networks into smaller, more efficient sub-networks .  Computers that belong to a subnet have identical  most-significant bit -group(24 bits are sam...

By Jayant Sharma So far we have learned only the documentation about what is Amazon EC2, what is an instance, etc. Now its time to do some practical implementation. That means today we will learn steps to create our first Amazon EC2 instance. The steps are given that demonstrate how to create an instance starting from choosing an AMI server to applying key pair encryption. Given below are the steps fir creating first instance. First, login to the AWS management console. Now, you are on your home page. Go to Services link on the header. After clicking on services, you found following page opened: Then under Compute, click on to EC2. And following page is opened. Now for launching an instance, click on the Launch Instance button. After that we have to follow some fundamental steps for creating an instance. This is the first step in which we have choose an AMI i.e an Amazon Machine Image, that consist of an Op...

Launching a Windows Server  By Jayant Sharma So, far we have learnt how to create an instance in AWS. If you missed it, then go to my blog and check that first. Link is given as: Amazon EC2: Creating first Instance Okay so now we have a windows instance running on AWS which we have created last time as shown below: Now we have to launch a windows on AWS. For this, we need to do following things. First thing you have to keep in mind that your instance must be in running state. Now click on the Action button: Now here you will find number of options. We have to proceed for Connect.  After this following popup will opened: First click on the download button. This will download a Remote client software that runs the windows. Now this remote client is password protected. So, you need to get the password. So click on the Get Password button. Here, you have to attach a key pair file you have previously created for encryption. Th...

By Jayant Sharma Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, re-sizable  compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers.  Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing you to quickly scale capacity, both up and down, as your computing requirements change.   Benefits of Amazon EC2 ELASTIC WEB-SCALE COMPUTING Amazon EC2 enables you to increase or decrease capacity within minutes, not hours or days. You can commission one, hundreds, or even thousands of server instances simultaneously. You can also use  Amazon EC2 Auto Scaling  to maintain availability of your EC2 fleet and automatically scale your fleet up and down depending on its needs in order to maximize performance and minimize cost. To scale multiple services, you can use  AWS Auto Scaling. COMPLETELY CONTROLLED You have comple...
