Ulitzer Cloud Computing Blog Things are changing fast in the world of Cloud Computing, however one question remains the same. Will it save me money and how much? To follow up on a previous post on Cloud Economics Part One, I looked at a fairly simple example of 5 Servers for a dev/test environment and identified the incremental costs of buying 5 servers and running them on premise or a Colo and then compared that to Amazon EC2. The analysis did not include many variables such as real estate costs and labor savings which may or may not apply to the particular situation. The results indicated that a Premise based deployment could provide the lowest "incremental" cost when compared to EC2 if the servers were running continuously. On the other hand EC2 provided significant savings for short term workloads with no upfront costs. Purchase - on Premise $ 15,000    Quad-Cor... (more)

Cloud Computing Economics, Part Two

Chris Fleck's Blog As described in part 1 of this blog series, the cloud is not the answer for every enterprise or every workload. This is true based on the current economics even without considering additional factors like security, control and SLA's. On the other hand the economics do point out a major cloud advantage when it comes to short term or variable workloads. (Pointed out by Michael Keen and Billy Marshall as well). Perhaps this is not very surprising to many, but it does help to look at the numbers to put it in perspective. The largest Intrinsic cost advantage of the ... (more)

Cloud Computing Economics, Part One

Chris Fleck's Blog The economics of Cloud Computing do point out a major Cloud advantage when it comes to short term or variable workloads. On the surface though it's apparent that Amazon's EC2, for example, is significantly more expensive if the set up is utilized 24x7x365, even a 40 hour week yields a slightly higher cost. Below is a simple comparison of Amazon EC2 vs. purchasing a set of servers for development purposes ( I have added some additional costs and scenarios). This example also assumes the servers fit in existing space and either environment would be managed by exi... (more)

Cloud Computing Economics - Amazon EC2 vs Terremark v Cloud Express

The recent announcement of the Terremark Cloud offering has raised significant attention especially because of the competitive pricing and EC2 like features of elastic capacity and hourly charges with no commitment. On the surface the Terremark entry price of $0.036 per hour seems very low compared to Amazon EC2 at $0.10 but it's worth picking a few examples to provide a more apples to apples comparison. Not included in the comparison is the difference in storage costs which can be small or very significant depending on the circumstance. Amazon provides up to 160 GB of instance... (more)

Is Nick Carr Right About Cloud Computing?

Chris Fleck's Blog There is a lot of hype and reality in the world of Cloud computing today. On the hype side there are numerous data points; VC investments, M&A, data centers under construction, new conferences and events. On the other hand there are now many examples of reality as well. SaaS offerings like Salesforce.com and many HR applications plus web site hosting have established themselves as a legitimate part of the IT portfolio of many corporations large and small. Adding fuel to the fire is extensive press, analyst and blog coverage (like this!) plus books like Nicholas... (more)
