Found a snippet of information about stabilising Cloud Computing. There are people out there that are in fact on to it (why wouldnt they). There is a fantasic blog all about cloud computing, if that interests you. Below is an excerpt from their blog post late last year!

San Jose 12 May, 2009

Monitis launches industry’s first deep EC2 monitoring service. Monitis Cloud Monitor records instantiations and terminations of virtual server instances, automatically configures Monitis agents for deep fault, performance and configuration monitoring, and provisions external availability monitoring. Cloud computing enables companies to attain scale on demand and hence reduced capital investments.

Amazon’s Web Services package is the market leader for on demand dedicated server provisioning and cloud computing. Virtual machine instantiation in Amazon EC2 is a minute and click away. Both startups and established companies are increasingly leveraging EC2 in their production systems. EC2 allows companies to scale to unlimited servers and payment can be tied to actual usage instead of monthly contracts. Users can run 20 servers per 1 hour or 1 server per 20 hour at the same cost.

Software can launch additional services on demand including ability to scale when it experiences heavy load. This has potential to create the following problems for the administrator: 1) cost escalation due to uncontrolled service launch and 2) inability for monitoring service to handle dynamic server instantiation. Monitis Cloud Monitor provides control over services running in EC2 by leveraging Amazon’s API for automated service management. Cloud Monitor leverages AWS account detail to regularly poll active instances, record changes in instance (start/stop) and executes user defined rules & actions including: ability to issue alerts, and setup additional internal/external monitors for new instances.

Monitis automatically configures its agent for probing server CPU, load, storage, and processes resource utilization. Monitis service provisions external http, ping, database and/or custom monitoring. An example of custom monitoring includes notification rules such as “notify if greater than 5 instances are running”, “add an agent for every new instance, start CPU & storage monitoring, and notify if CPU utilization is more than 80%”, etc. “There is tremendous growth in on demand cloud computing and we see growing need for explicit cloud monitoring” said Hovhannes Avoyan, “with our customer first policy, we are here to address the need and we provide a fast, easy, affordable tool”.

Monitis Cloud Monitor is web centric software and no downloads are required. The service is expected to be used by both site owners and IT service providers

Knowledge Base - Cloud Computing...?

Posted in Labels: , , , |

Cloud Computing (not physically, though I know alot of people this is one of their wishes)

Cloud computing is Internet- ("cloud-") based development and use of computer technology ("computing").[1] In concept, it is a paradigm shift whereby details are abstracted from the users who no longer need knowledge of, expertise in, or control over the technology infrastructure "in the cloud" that supports them.[2] Cloud computing describes a new supplement, consumption and delivery model for IT services based on Internet, and it typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet.[3][4] (Wikipedia)

Cloud Application Examples

Cloud Platforms Examples

Characteristics of Cloud Computing

In general, cloud computing customers do not own the physical infrastructure, instead avoiding capital expenditure by renting usage from a third-party provider.

They consume resources as a service and pay only for resources that they use. Many cloud-computing offerings employ the utility computing model, which is analogous to how traditional utility services (such as electricity) are consumed, whereas others bill on a subscription basis. Sharing "perishable and intangible" computing power among multiple tenants can improve utilization rates, as servers are not unnecessarily left idle (which can reduce costs significantly while increasing the speed of application development).

A side-effect of this approach is that overall computer usage rises dramatically, as customers do not have to engineer for peak load limits.[9] In addition, "increased high-speed bandwidth" makes it possible to receive the same response times from centralized infrastructure at other sites.(Wikipedia)


Cloud computing is the combining of all gadgets enabling access to all personal/work information – any time, anywhere.

The iPhone can be used to access the same files and music that the desktop machine used at home can. You are able to travel with the laptop and just pull down your data from the internet. The data remains secure, backed up in the ether and forever available.

Living the dream? Or “Living in the cloud”….

Risk 1.

Your most important files are the ones you need with you at all times, or at least at any time. But what if the internet connection is down? How do you get the spreadsheet from Google docs, or refer to the map in that email when you are offline?

The standard scenario is that you have your connection chopped of when you’re on a plane, although I actually like the relaxing offline time of a plane ride. This is a problem, but in truth you are cut off whenever you are away from home or office.

3G modems?

Work best when using small data sizes, but the networks are still too slow for shifting big files like music, photos or movies. When outside 3G coverage (possibly your next holiday destination), you may as well be on dial-up. Wi-Fi is no way for the professional to work…

Resolve this risk!

Notebook with a day-long battery life and a guaranteed, 24/7 connection that’s fast enough to stream HD video. We’ll imagine that you get a cheap plan with no crazy bandwidth caps. Would this work?

Your thoughts?
