Hyper-V, an Introduction on simple-talk.com

Posted by mikeg on June 13, 2009

Very detailed introduction by Jaap Wesselius

http://www.simple-talk.com/exchange/exchange-articles/windows-server-virtualisation-hyper-v,-an-introduction/

Microsoft Windows Server 2008 Hyper-V was released in the summer of 2008 and is Microsoft first real hypervisor virtualization solution. It is not an emulated environment like Virtual Server or Virtual PC, but as a hypervisor solution it “sits” between the hardware and the Operating System. With the Integration Components installed you can fully use the functionality offered by Hyper-V. You have to secure the Parent Partition as much as possible to prevent compromising the complete system.

In the next articles I will talk more about the Hyper-V best practices, deploying Virtual Machines, using the System Center Virtual Machine Manager (VMM) 2008 and the “high availability” options and why these aren’t really high available in the current release of Hyper-V.

Amazon EC2 Vs GoGrid

Posted by mikeg on June 13, 2009

We are considering moving some of our websites from a managed server into the cloud, but we like the convenience of a “managed support”:

  • available 24×7, minimal hold time
  • ability to setup SOP (standard operating procedure) of what needs to happen if anything goes down
  • escalation procedure — try to restart service, clean this and if that doesn’t work only then call one of predefined phone numbers
  • etc

There are monitoring tools that are available for EC2 specifically (see my previous post here) or just standard networking tools (Nagios, Spiceworks, etc) but most of them still require us to hire staff to react to unexpected events

I looked into GoGrid and while it has a potential, it is not suitable for us just yet.

Positives:

  • 24×7 support — don’t know what it means. My expectation is outlined above
  • Graphical interface — while I didn’t like the design, it was user friendly
  • Free Load Balancer
  • Free Public IPs
  • Windows 2008 Images

Negatives:

  • Cannot use my own image, cannot backup/clone an image that I setup within GoGrid — that pretty much explains why they don’t have auto scaling (next bullet point)
  • No auto scaling (roadmap)
  • Even if machine is “off” — they still charge you money as if it was ON. On their roadmap.
  • Only 4GB machine gets its own single Xeon core (equivalent to P4 2.0 chip). Lower RAM images get fractions.
  • No multi-core support
  • While their Cloud Storage pricing is inline with Amazon, Data Transfer is $.50/GB Vs Amazon’s $.17/GB for first 10 and then goes down from there. Significant difference
  • Amazon offers CDN and GoGrid doesn’t
  • Amazon offers multiple datacenters and GoGrid doesn’t

We don’t do porno sites and a professional windows server administration :).

Posted by mikeg on June 13, 2009

We were asked by a client to find an offshore company to do 24×7 network/system monitoring/administration. Clients runs Windows network/servers. Title of this post is a quote from one of the responses. Very funny.
