Let’s Start With AWS-EC2.

  • It’s just a click away from you. One just have to chose type of machine, select the hardware specifications, memory consumption and security group according to the roles and policies defined accordingly.
  • It also provides Amazon Machine Images (AMIs), that package the bits you need for your server (including the operating system and additional software). Moreover you can create snapshots of your machines (Instances).
  • Secure logins and access via different user groups and secure key pairs. Furthermore Firewall options (different incoming and outgoing rules applied to the server using security groups).
  • Public/Static IPv4 addresses available for all EC2 instances also termed as Elastic IP addresses.
  • Many physical locations available for your resources, on different Regions and Availability Zones.

  • Type The protocol to open to network traffic. You can choose a common protocol, such as SSH (for a Linux instance), RDP (for a Windows instance), and HTTP and HTTPS to allow Internet traffic to reach your instance.
  • Source is the other options, which is to specify from where you want to give access to your instance, let’s say if I input my IP address in the source option, then the instance can only be accessed via my IP address. Same as if I input/select the option to all, it can be accessed from all over the world, which is obviously not a good security practice. I can also provide custom IP addresses for this option in which I can specify those IP addresses to whom I want to give the access to.
  • Create a New key pair : This option will create a new key pair for you to access the instance, make sure to save your private key properly in order to access the instance via keys.
  • Choose an Existing key pair : This option will give you option to chose any existing key for you to access the instance, if you have already created the key.
