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.

How to Set Up a Gluster File System within the GoGrid Cloud (Part 1)

Friday, August 19th, 2011 by

In this blog post series, I want to take a closer look at a storage technology called Gluster File System, and how it can be set up (this article), connected to (article #2) and expand storage (article #3). This is the first blog post of the series and I will review what GlusterFS is, why you would consider using it, and how to deploy it using the GoGrid GlusterFS Partner GSI.

GoGrid offers a great storage solution called Cloud Storage. But what if you want to deploy your own storage so that you can directly control performance and redundancy? What software would you use to provide this? The simple answer is Gluster. It is a powerful software-based storage solution that offers a centralized controlled storage pool management system that is very easy to use.

There are many different ways to take advantage of the GlusterFS storage solution. (Note: in the descriptions below a “brick” is a GoGrid Virtual Server.)

1. Distributed Volumes:

“Distributed volumes distribute files throughout the bricks in the volume. You can use distributed volumes where the requirement is to scale storage and the redundancy is either not important or is provided by other hardware/software layers.” – Gluster.org

GoGrid Cloud Survey Report – Operating Systems in the Cloud (Part 6)

Monday, August 1st, 2011 by

When most people hear the phrase “operating system in the cloud” they usually think of a really cool client-side, Web-based desktop like EyeOS or CloudMe or even Chromium OS. Perhaps that is the future of client operating systems, but when cloud infrastructure providers talk about operating systems, they are making reference to which OS your cloud infrastructure will run on. And, it’s not always limited to just one in many cases.

OS_choices

At GoGrid, we provide a variety of operating systems including:

  • Windows Server
  • Ubuntu
  • Red Hat Enterprise Linux
  • Debian
  • CentOS

Operating systems in the cloud are very important because they are what your applications and infrastructure are built upon. Whether you’re using the cloud to deploy test & development environments, act as your data center or run your company’s business critical applications, the operating system plays a vital role in cloud infrastructure.

Most IT professionals are pretty passionate about what operating system they prefer. For instance, search for “Windows vs. Linux” on Google – over 109 million results have some sort of opinion on the topic. But, since actions speak louder than words, we wanted to determine which operating system was used more by the IT industry.

The Importance of Building Your Cloud Infrastructure the RIGHT Way

Thursday, July 21st, 2011 by

The cloud is great for so many things. You can create a web presence in a matter of hours or completely implement an N-tiered, redundant, elastic, secure globally-available cloud topology. Spinning up infrastructure via a web portal or API in minutes via a few clicks of a mouse is a dramatic transformation from the days of racking and stacking servers, untangling miles of cat5/6 cables, connecting load balancers and firewalls to the mix and hooking up storage devices. And let’s not forget about physical security, power supplies, cooling and network redundancy. The neat thing about the cloud is that all of the stuff has become really easy to do and you can do it very quickly.

GoGrid has a long history of enabling IT infrastructure solutions for companies across the world. We have built out core services and offerings to allow businesses to build want they want quickly, efficiently and with state-of-the-art cloud technology. But just because you have great tools at your disposal doesn’t mean that your cloud environment will magically create itself. And that is something that we realize and understand at GoGrid.

Architect for Success

Cloud computing can be almost magical at times, but we need to remember the processes and best practices for security and ensuring redundancy that we are accustomed to using, and adapt and use them within the cloud as well.

A few weeks ago, I wrote a post “Things to Think About When Building Secure Infrastructure” where I made a few points about “assumption,” namely, assuming that whatever cloud vendor you choose, they will take care of everything for you. Regardless of the cloud vendor, you need to do your due diligence and update your standard operating procedures to reflect how cloud computing works. It is different than traditional IT in many ways. For example, in the GoGrid cloud, you can create a cloud server, harden it with security software and configurations and then save it as a MyGSI (as “server image”). Then, as you need to scale out your infrastructure, you can do this not only quickly, but securely as well, by deploying clones or instances of that hardened server. With a traditional, physical deployment, it takes much longer and there is no guarantee that you will have each and every security patch in place on every server.

How to Monitor Your Windows 2008 Server on GoGrid with Cacti 0.8.7g

Tuesday, June 14th, 2011 by

This is the 3rd and final post in my setup and use of the GoGrid Community GSI server for Cacti Monitoring. In my first post, “Set Up A Cacti Monitoring Server in Minutes with this GoGrid Community Server Image,,” I covered how to deploy Cacti in your GoGrid environment using a Community GSI. My second post, “How to Monitor Your Ubuntu Server on GoGrid in 6 Steps Using Cacti 0.8.7g,” I discussed how to initiate monitoring of your GoGrid Ubuntu server. Now to round things off, I want to show you how to link up your Cacti monitoring server to a Windows Server 2008 server on your GoGrid network. The base install of Cacti 0.8.7g will allow you to monitor the server’s bandwidth utilization, Ethernet errors, number of logged in users, and total number of processes. There are other templates available to monitor other components and services on your Windows server, but they require using an additional SNMP service beyond the Microsoft SNMP service. My blog post won’t get into the latter, but I will cover the former.

Objectives:

  1. Configure GoGrid private network connectivity on Windows 2008 Server and test connectivity to Cacti server
  2. Configure and start Microsoft SNMP service on your Windows 2008 Server
  3. Add new Cacti device
  4. Create graphs to log Local Connection and Local Connection 2 bandwidth and errors, Logged in Users, and server processes

Configure GoGrid private network connectivity on Windows 2008 Server and test connectivity to Cacti server

Below we see that we have a server (“Web2”) deployed on GoGrid with a public IP. Let’s log into this server and configure the private network with a private IP from the same subnet of the Cacti Monitor server. As I described in my previous post – I am using the prescribed private IP subnet from my GoGrid portal, contained under the List tab and then under Network – Private Network.
