We often talk about CloudSwitch moving legacy applications to the cloud in a simple and secure way; this raises the question of what exactly we mean by “legacy.”  To be more specific, we mean a broad range of apps—including third-party, custom and customized off-the-shelf applications—basically any application that has been developed in your current environment without specific design for a cloud. It turns out that these existing applications are very important in cloud computing. When we started building CloudSwitch, we were focused on the hybrid cloud computing model; that is, some components must stay in the data center and other applications and functions can move to the cloud. However, it became apparent that “stretching” applications between the data center and cloud only works for certain types of deployments due to the added latency between the data center ... (more)

What Cloud APIs Show Us About the Emerging Cloud Market

While there is no “official” definition of cloud computing, I believe programmatic access to virtually unlimited network, compute, and storage resources is an essential characteristic.  Even though many users access cloud computing through consoles and third-party applications, the foundation of a cloud is a solid Application Programming Interface (API). Since CloudSwitch works with many cloud providers, we have the opportunity to interact with a variety of cloud APIs—both active and soon-to-be-released versions.  After working closely with both the APIs and those implementing t...

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...

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...

Cloud Computing Standards – Not This Year

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 fo...
