3 Tools for Getting VMs From Your Datacenter to the AWS Cloud

Here’s a simple scenario: you have some Virtual Machines (VMs) in your on-premises environment, likely in VMware vSphere or Microsoft Hyper-V. You want to either fully migrate some or all of those VMs to the AWS Cloud or you want to copy a gold image to the AWS Cloud so you can launch compute instances from that image. Simple enough.

Now, how do you do it?

Can you just export an OVA of the VM, copy it up, and then boot it? Can you somehow import the VMDK files that hold the VM’s virtual drive contents? Regardless the eventual method, how do you do it at scale for dozens or hundreds of VMs? And lastly, how do you orchestrate the process so that VMs belonging to an application stack are brought over together, as a unit?

Five Features of Brocade VCS

Virtual Cluster Switching (VCS) is Brocade’s brand of datacenter ethernet switching. VCS allows for the creation of a network fabric that’s capable of converging storage and data traffic via standards-based datacenter bridging. It also solves the “Spanning Tree Protocol (STP) problem” by implementing a standards-based TRILL data plane paired with their own control plane in the form of Fabric Shortest Path First (FSPF). This data + control plane enable the “routing” of MAC addresses through the fabric, negates the need for STP, enables the use of all cabled links, and prevents traffic loops. VCS is only (currently) available on the VDX line of switches from Brocade.

In this post I’m going to outline five aspects of VCS that I found particularly interesting or unique. This is a companion article to an earlier one titled Five Functional Facts about FabricPath where I broke down five features of Cisco’s fabric technology.

Blogging the Cloud Track at Cisco Plus 2011

I attended the Cisco Plus Canada Roadshow in Calgary recently and sat in on a day of presentations related to Cisco’s data center/cloud offerings. The sessions where quite good and I ended up taking quite a few notes. I thought I’d blog my notes in order to share what was presented.

The four sessions were:

What Does The Cloud Mean To Your Network?

If you’re an IT professional you’ve probably been hearing a lot about cloud computing lately. I know I’ve sat through a number of seminars and sales pitches where people have been touting public cloud services on the merits of lower cost, reducing infrastructure and quicker implementation of services. However, I’ve noticed that almost none of these presentations discuss the increased reliance on Internet connectivity. With all the focus on the benefits of cloud computing, it’s easy to forget that there has to be a trade-off. In order to offer reliable, quality access to public cloud services, your Internet connectivity likely needs some tuning. Continue reading What Does The Cloud Mean To Your Network?
