According to a Gartner market analysis report on cloud services over 2012-2016, cloud infrastructure as a service (IaaS) spending will exceed $72 billion, with a compound annual growth rate (CAGR) of 42 percent. Cloud infrastructure as a service (IaaS) providers offer virtual machines and supporting resources, including networks, firewalls, Internet connection, electrical/facility and other infrastructure needs. Additional managed services might include IT disaster recovery, cloud-based disaster recovery, offsite backup, SAN-to-SAN replication and more managed by certified professionals. A projected 19 …

VMWare recently stepped out with a new advancement in their infrastructure – vSphere 5.0. VMware vSphere 5.0 provides major enhancements to the entire cloud and infrastructure stack. VMware vSphere 5.0 supports “virtual machines (VMs) that are up to four times more powerful than previous versions with up to 1 terabyte of memory and 32 virtual CPUs,” according to VMware.com, meaning it tackles even the toughest Tier 1 application requirements. These VMs will also be able to process 1 million I/O …

The Cloud Computing Spectrum

Posted on June 22, 2011 by

I recently gave a talk on the key trends in cloud computing and to set the stage, I was asked to describe the spectrum of cloud computing options from private cloud computing to public cloud hosting. Here is a snapshot of one slide I used to describe this spectrum of cloud computing.  On one end of the spectrum you have private cloud computing – dedicated to a single company, designed around high availability (in most cases), secure and very capable …

As we round the bend half way through 2011 (the year of cloud computing), we’re seeing some interesting trends emerge in cloud computing.  Here are 6 key trends in cloud computing that I’ll be discussing at our Cloud Computing Seminar next week. More Confusion (Not Less) About What Cloud Computing Represents – We expected the definition of cloud computing to shake itself out by the end of this year.  If anything, all of the hype around the cloud is fraying …

In previous blogs I wrote about the benefits of private cloud computing and the benefits of public cloud computing based on the unique models of each. Sitting between secure, dedicated private cloud computing and open, low cost public cloud hosting is a secure, shared cloud middle ground we call managed cloud hosting. Public cloud hosting is typically built around the “compute as a utility” model where cost is the driving consideration, overriding security and availability, to deliver commodity-level pricing where …

Cloud Computing is moving into 3 separate distinct directions: Public Cloud Computing – like Amazon’s EC2 and Rackspace, designed to provide the lowest cost shared computing service with a utility delivery model where you can pay for services by the hour. Private Cloud Computing – the opposite end of the spectrum where the entire cloud infrastructure (servers, storage and network) is dedicated to a single company. Managed Cloud Computing – where a secure private cloud is sold by the server. …

What is Managed Cloud Hosting?

Posted on February 11, 2011 by

There are a number of public cloud options available. Some like Amazon’s EC2 are basic cloud servers designed to provide the lowest cost computing services for non-critical applications like web or development servers. Others are designed to deliver the high availability and security that enterprises require in their private clouds. The later, we call “Managed Cloud Hosting”.

How I found out I wanted “Predictably Priced Elastic Computing” We have a really important web application that gets a fairly unpredictable flow of traffic from multiple sources including users. I wanted to know what it would cost to host this application “in the cloud.” I thought it would be really easy to buy a “cloud” server and move my application there. But first, I wanted to forecast the costs. I decided to check Amazon EC2 and Microsoft Azure. Without …

Public Cloud or Private Cloud?

Posted on September 27, 2010 by

“Cloud computing” is still used to mean a lot of things to a lot of people. When it comes to slicing up the cloud taxonomy a little further, there’s still quite a bit of confusion between the public cloud and private cloud computing.

According to Tom Bittman, vice president at Gartner, IT managers are more concerned with security and privacy than they are with the next three public cloud problems combined. In a separate poll on public cloud computing versus private cloud computing, 75% of IT managers said that they will be deploying a private cloud strategy by 2012 and 75% will invest more in private clouds than in public clouds through in the next 2 years. Gartner believes that the investment in …
