Today, June 8th, is World IPv6 Day. What does that mean exactly? Well, the internet is running out of IPv4 addresses and today, some companies around the world are testing out their sites using IPv6, a networking protocol that aims to replace IPv4 in the coming years. So, today is the day to raise awareness of IPv6. It’s NOT a transition day – the transition will take years to accomplish – it IS a time to evaluate your IPv6-readiness on your sites, applications, hardware, software or anything that uses IP addressing protocols.
IPv4 Networking Protocol
IPv4 is a networking address space that most of us should be familiar with. It is a numeric, 32-bit only, and takes the form of XXX.XXX.XXX.XXX (so like 192.168.100.000). There is a physical limitation to the number of IPv4 addresses you can have, 2^32 or 4,294,967,296 to be exact, and we are running out pretty quickly. Every website has an IP address bound to it. We, as consumers, are used to typing in domain names (like www.GoGrid.com). But what happens is that the domain name is translated into an IPv4 address (like 184.108.40.206). Think of IP addresses like an “internet phone number”. Nowadays, we click on a name (e.g., a domain name) to call someone. In the past, we dialed a phone number (e.g., an IP address).
Remember, not all of those combinations can be used as some are reserved:
Reserved address blocks
|CIDR address block
||Current network (only valid as source address)
||TEST-NET-1, Documentation and example code
||IPv6 to IPv4 relay
||Network benchmark tests
||TEST-NET-2, Documentation and examples
||TEST-NET-3, Documentation and examples
||Multicasts (former Class D network)
||Reserved (former Class E network)

So far, in the GoGrid Cloud Survey Report series, we received data from over 500 CTOs, developers and IT professionals that answered the questions “What is Cloud Computing?” and “Does Your Company Use Cloud Services?”; even more interesting was the information these respondents gave that showed a Significant Increase in IaaS Adoption in 2011.
The insights we have received have been fascinating and we will continue to break down the survey results and release the findings here on the GoGrid Blog. This week we discuss the data received from our IT respondents on how they currently use cloud computing and what use cases would cause a migration to cloud computing services.
Cloud Computing Use Cases
Because cloud computing spans SaaS, PaaS and IaaS, it isn’t a surprise that many of our respondents use cloud computing services. Our first post in the series highlighted the fact that 65% of IT professionals surveyed use cloud computing in some way, shape or form. What is surprising are the use cases we received when we asked, “What use cases are you currently using in the cloud?”

In my previous post, “Set Up A Cacti Monitoring Server in Minutes with this GoGrid Community Server Image”, I showed how to use a Community GSI to quickly and easily set up a monitoring server on GoGrid running Cacti. In this second part of the Cacti GoGrid Community GSI blog series, I would like to walk you through how I connected my Cacti server up to an Ubuntu server (a node in my Glusterfs file storage array). First we will review the objectives we are looking to achieve and then dive into each one.
- Confirm private network configuration on both Cacti server and Ubuntu server, and test connectivity.
- Enable SNMP server and configure SNMP rocommunity string on Ubuntu servers.
- Establish SNMP agent listening IP address
- Create “Device” in Cacti console and confirm SNMP connectivity to Ubuntu server
- Create Graphs – CPU usage, Load Average, Memory Usage, PING Latency, Processes, Eth0 Traffic, Eth1 Traffic
- Repeat process for other Ubuntu servers in your network.
Confirm private network configuration on both Cacti server and Ubuntu server, and test connectivity
On GoGrid, you have the ability to network your servers together over a private network allocated to your account. (Note: all private networking within GoGrid is free.) We need to take advantage of this secure communication method to allow your Cacti server SNMP access to your servers. I recommend you use the private network IP range that is specified in your account – under the “List” tab then “Network”.

Don’t let the media fool you. Which of these actually make cloud computing financially compelling?
- Super cheap power, such as hydro-electric
- Shipping container datacenters
- Massive datacenters
- Blade servers
- Datacenters with super-efficient cooling
- VMware virtualization licenses
- Pay-as-you-go pricing
- Shared platforms
- Commodity hardware
The answer is NOT “all of the above”! If you said “pay-as-you-go pricing, automation, shared platforms, and commodity hardware” then you win. In fact, these four concepts are so powerful that I believe that they will shrink the entire IT economy. IT shrinking? How could that be possible? Yes, I think that the $3.3 trillion dollar global IT economy could be cut in half. When I’ve made this declaration before I’ve been likened to the commissioner of the US Patent Office who was rumored to have said:
“Everything that can be invented has been invented.”
Charles H. Duell, Commissioner, U.S. patent office, 1899 (attributed)
In truth he didn’t say this. http://en.wikipedia.org/wiki/Charles_H._Duell
But I’m still saying that I think we’re currently seeing the peak of complexity and cost in IT. IT is going to get easier and less expensive from this point forward. There. You have it in writing. Read the rest of this entry » «The Actual Truth About the Economics of Cloud Computing»

With so many different types of cloud infrastructure available – public, private, internal – and with so many conflicting opinions in the industry, finding the right cloud for your business can be a confusing and frustrating process.
In order to bring clarity and understanding, we recorded a new educational webinar, hosted by GoGrid, where guest speaker James Staten, Principal Analyst, Forrester Research Inc., and Mario Olivarez, VP of Product Management of GoGrid share new research and discuss the status and direction of the Cloud infrastructure landscape.
These cloud experts discuss:
- The 4 characteristics of cloud computing
- Why are companies using the Cloud?
- What is the difference between Public and Private Cloud?
- Why is 2011 the Year of the Hosted Private Cloud?
- What is the ROI of the Cloud?
The recorded webinar also includes all the answers to the questions submitted by the live audience.
So if you are interested in learning more about the cloud industry or want to have a greater understanding of how cloud computing technology can help your business The Future of the Cloud will be well worth viewing. Starting today, this webinar is now available as a free download (.wmv and .mov versions available).
Please download the webinar by clicking the download link and leave your thoughts in comment section on this blog post.
