I would highly discourage a non-technical person from trying to manage a foreign outsourced software project. For what it's worth, I've managed a few such projects over the years with developers in India and China. My experience has been th

I was at the Cloud Connect conference last week. In a session on cloud performance Adrian Cockcroft (Netflix's Cloud Architect) spoke and said they do not use EBS for performance and reliability issues. They initially had some bad experienc

I just created a very similar http-based ping based on this, but with the following difference: * Use JSON-P to avoid same-origin-policy request failures (this also fixed the Opera failures) * Repeat request 6 times (1 warmup + 5 measured)

How are you getting around same-origin-policy issues with this script? I noticed the javascript debugger is reporting failures for every request: "Origin http://www.cloudping.info is not allowed by Access-Control-Allow-Origin.". Are you j

Capturing and recording these latency measurements and associating them with the user's location would be fairly easy with MaxMind's free GeoIP databases and Apache module mod_geoip.

This is great, very close approximation to actual latency. We had a similar need on our cloud speedtest http://cloudharmony.com/speedtest and implemented using a Java applet that executed and screenscraped an OS ping to capture latency. W

This is cool, but not earth shattering. It is essentially a management stack/abstraction layer/deployment tool on top of existing AWS services: EC2, CloudWatch, load balancing, route 53, autoscaling, AMIs. It is a PaaS sort of... but single

+1 for apigee - we just migrated our web services and the stats, graphing and real-time debugger are excellent. Migration was super easy.

There are some distinguishing factors between IaaS clouds and VPS: paygo pricing (VM & bandwidth), API, self-service automated provisioning, no term commitments, scale-up/down (CPU, memory), VM imaging/cloning/templating, off instance s

Let's add to this hypothetical... assuming a similar distribution of wealth as in the US and these 10 men had a total wealth of $1000. The top 2 would hold $425/each, the next 2 $50, the following 4 around $10, and the remaining 4 $2.25.

Here are my own availability stats for Linode this year. We use Panopta to monitor each data center. All are within the SLA: Dallas - 99.951% Newark - 99.969% London - 99.986% Fremont - 99.989% Atlanta - 99.995%

From status page: Initial indications are pointing towards another power outage. We are now working on bringing Linodes up as soon as possible. We will continue to post updates as we have more information. http://status.linode.com

For what it is worth, we've had 99.998% uptime for static files on appengine - not using datastore or any other features (about 11 minutes of legitimate outages the past year). During the same time period we've had 100% uptime for m1.small

Rackspace Cloud has data centers in Texas and Illinois. However, they don't let you choose (your account is assigned to one data center at the time of creation). EC2 certain offers a lot more flexibility in this regard with EC2 data center

This is true, generally all Rackspace Cloud servers perform about the same in terms of CPU and disk IO, so the small Rackspace instances will outperform small EC2 instances. However, they don't scale well and on the high end, they under-per

Another distinguishing factor between Rackspace Cloud and EC2 or Linode are bandwidth caps. Rackspace limits outbound public network throughput to 10mbps for 256mb instances to 70mbps for 16gb instances. EC2 and Linode both provide an uncap

Rackspace Cloud used to have the upper hand on smaller sized instances. This is no longer the case with EC2's new 640mb micro instance at about $8/mo reserve. Not top performer, but it gets the job done for lower traffic servers.
