          Arcus Region Migration Services (ARMS) for migration across AWS Regions Background: In the last year alone more AWS regions have been announced and established than ever before in a year. Existing AWS Customers in these countries / regions, now have the option to migrate to a near shore region and this phenomenon is expected to continue, like in Korea, & now in India. In the past customers from these countries, would have hosted in another region like Singapore or Japan and would have to experience...
  • The Background Amazon offers VPC for creating a secured private network space, to host and run their Servers. In AWS VPC, you can create public & private subnets. Public subnets are used to host the Internet facing servers (mostly web / application servers) that you want inbound internet traffic allowed to and private subnets for backend instances (mostly Database servers) that you do not want to be directly addressable from the Internet. These DB Servers would still need access to internet for their updates and any other Interfacing that may need to be made to the internet. This is...
  • In this article series we will look at the steps in creating a Whirr base instance which will be used to launch the Hadoop cluster over your custom created instances  ”using AWS VPC – BYON(Bring Your Own Network)”, ie., on pre-setup machine instances in AWS VPC. In this article we will focus on how to install whirr in the Whirr Based & how to launch the hadoop cluster  As discussed in the Part 1, we should have a whirr base with the whirr tar deflated in the Ubuntu home directory. Step1: Next step is the log on to get whirr in path. You can use other ways of adding to path...
  • For those of us who have been through setting up VPC(Virtual Private Cloud) in AWS know the need to have a NAT instance running. Since we have to keep this instance running as long we need the easy internet access from instances running in Private subnets, had always wondered how else can this instance be utilized. In reality these NAT instance are doing a outward Port Address Translation from internal Private Subnet instances to external Internet. Typical NAT Server in AWS: While, there are those who may argue that the NAT instance better be left alone, we believe there...
  • In this article series we will look at the steps in creating a Whirr base instance which will be used to launch the Hadoop cluster over your custom created instances  "using AWS VPC - BYON(Bring Your Own Network)", ie., on pre-setup machine instances in AWS VPC. In this article we will focus on how to create a Whirr base instance.  Key challenge in getting a hadoop cluster through Whirr - BYON over Amazon AWS VPC, is that each instance in the Hadoop clusters should have a hostname which is traceable both by forward and reverse dns lookup in their network. Any AWS VPC instance is...
