How to Configure Static Routes to Traverse Traffic on CloudLink

Wednesday, February 1st, 2012 by

CloudLink is infrastructure so it can enable many use cases. However, you will be unable to use it until you configure your servers to use static routes. The rest of this post will describe how to create a static route from one server in US-West-1 to servers in US-East-1. This assumes that you have not already assigned a private IP to the West server. This guide assumes that you have a basic knowledge of Linux and/or Windows and with the basic principles of networking.

Find your Private IPs

First, you will need to find your private IPs. You can find your private IP block by going to the GoGrid portal, selecting the List tab and then Network. Under Type: Private you will see your private IP blocks. In this example, this is a listing of private IP blocks for US-West-1. US-East-1 has a DIFFERENT private IP block. The gateway is +1 from the first number in your private IP block (10.109.32.1) in the example above.

How To Set Up Private IP Segregation with CloudPassage in the GoGrid Cloud

Thursday, September 29th, 2011 by

CloudPassage is a key security partner that has images available on the GoGrid Partner Exchange. The CloudPassage images on GoGrid come pre-installed with their Halo daemon. This is available on CentOS, Debian, Red Hat, and Ubuntu on both 32-bit and 64-bit flavors. Alternately, you can launch a GoGrid base image and install the Halo daemon on your own. This tutorial assumes that you have a basic understanding of Linux and SSH as well as basic firewall strategies. It also assumes that you know how to configure private IPs so that will not be covered here.

How to Configure Zeus’ New Load Balancer in the GoGrid Cloud

Wednesday, September 14th, 2011 by

Zeus is a new GoGrid partner that provides a software load balancing product as a partner image called “Zeus Load Balancer 200Mbps”. There are three immediate features that come to mind when thinking about how to leverage Zeus within GoGrid: Load Balancing, Failover and Clustering. Note that this first image is a preview with certain feature set. It contains the majority of Zeus features but is capped at two clustered servers and 200 Mbits of bandwidth. Additional images are expected to be released by the end of the year.

This tutorial assumes that you have basic understanding of Linux and SSH as well as basic load balancing and failover strategies.

Cross Data Center Load Balancing / Failover

One of the main uses cases for Zeus is to load balance servers in the same data center. However, a more interesting use case is to quickly and easily load balance web servers within one data center and support failover to another data center. The process is straight forward. First, deploy the Zeus partner image as a VM with 1G RAM in the US-West-1. This example assumes that you already have web servers running on both the US-West-1 and US-East-1 data centers.

Once the Zeus image has been deployed, SSH into the server using the root login. Your logins can be found in the GoGrid web portal by clicking on the server icon, then Tools > Passwords.

We recommend changing your automatically created, default password as soon as you login.
