In the previous segment, you learnt about the services provided by AWS and understood how to AWS console.
In the following video, you will learn the steps on how to create a VPC and security groups. you will also learn how to launch a t2.micro EC2 instance.
Here, the t2. micro type instance will be launched for your practice and should be terminated as per the instruction. you will be shown the steps to lanuch a single node m4.xlarge EMR cluster later in the session. you will be using a similar configuration for your big data tools practice throughout the program with some changes to the software installed during setup, as required by the module.
Note:
The AWS console has recently made some changes to its user interface. in order to get interface matching with the video, follow the steps mentioned in the following document, after the completion of the steps, you can start with your video. before going forward with the video, make sure region is to set to N.Virginia.
Amazon Virtual Private Cloud (VPC)
The Amazon VPC allows users to provision an isolated section of AWS according to their requirement. Users can utilise the resources of AWS in a virtual network. They can also customise their virtual environment according to their needs.
Note:
The VPC setup is a one time process and you can make use of the VPC created here in the instances that you’ll launch in the future.
Security Groups:
A security group is associated with every EMR and EC2 instance. It provides security at port and protocol access levels. Each security group acts as a firewall for the instance and has a defined set of rules that filters the traffic coming in and going out of the instance. A security group mainly consists of two types of rules: inbound and outbound. The inbound rules define the incoming traffic to the EMR instance. The outbound rules define the outgoing traffic from the EMR instance. The VPC uses security groups to control the traffic at the instance level.
