Top Stories by John Considine

I started out writing a blog about the state of cloud computing to review how things have evolved in the cloud space over the last year (2010 was a good year for cloud computing) but I got sidetracked thinking about how clouds are converging, or in reality, not converging. It’s clear that end users of cloud computing would like to see true interoperability.  Companies want the freedom to pick a cloud that meets their needs, without worrying that choices made today will cost them big in the future or lock them in.  Interoperability would mean that a company could choose a cloud for a given workload, and if conditions change, they could opt to bring the workload back in-house or move to another cloud environment – without requiring a major engineering project or a shift to a different computing paradigm. However, there are several things working against this interopera... (more)

Amazon's Outage: Winners and Losers

In case you haven’t heard, last week Amazon’s Web Services had an extended outage that affected a lot of cloud users and has created a big stir in the cloud computing community.  Here is my take on the outage, what it means, and how it affected both us and our customers. First, the outage – Amazon’s Elastic Block Storage (EBS) system failed in one “small” part of Amazon’s mammoth cloud.  The easiest way to identify with this failing system is to think of it as the hard drive in your laptop or home computer dying.  Almost everyone has experienced this frustrating failure and it i...

Why Cloud Federation Requires Layer-2 Connectivity

Hybrid clouds are achieving almost universal buy-in as the way enterprises use the cloud. As we’ve described previously, the hybrid model federates internal and external resources so customers can choose the most appropriate match for workload requirements. The approach is already transforming enterprise computing, enabling a new generation of dynamic applications and deployments, such as: Using multiple clouds for different applications to match business needs Allocating components of an application to different environments (e.g., compute vs database tiers), whether internal o...

Opinion: "Cloud in a Box" Gets Boxed In

Just a week after our blog post on the telcos, we find another big company joining the cloud computing tsunami – Oracle’s announcement of its “cloud in a box” offering as well as new offerings of Oracle software running on Amazon’s EC2. For a company whose leader shunned the term “cloud” last year, this is a lot of cloud announcements in one week.  Oracle’s new Exalogic Elastic Cloud is perhaps the first “cloud in a box” solution that is actually delivered in a box (of hardware).  Unlike the offerings we have seen from Eucalyptus, Nimbula, Azure, and VMware, the Exalogic product...

Image Conversion and VM Imports in Amazon

Amazon has announced another important tool in their ongoing platform innovation for EC2 – the VM Import tool. This converter allows you to “bring your VMware images to the cloud.” As we’ve seen extensively at CloudSwitch, this is a primary use case for most enterprises – the ability to take images you’ve already built (likely in VMware) and migrate them into the cloud. It’s great to see Amazon continue to innovate around these gaps in their offering, as this continues to drive the overall market growth and enterprise adoption. But it’s important to understand what this means f... (more)
