The Purely Public Cloud Deployment: The Perceived Risk

In this post series, I will raise some basic questions and will delve deeply into this topic to debate the common resistance to what I call “pure cloud deployment”.
Let’s begin with a leading question: Can’t the hybrid economy model live within the public cloud? From the enormous number of conversations with top cloud thought leaders, CIOs, startups, and the like, it seems that the answer is YES.

Secure Your Cloud Building Blocks: Overview and a Few Tips

With IaaS dynamic environment you pay only for what you use enabling alignment with actual real-time demand. The cloud instance is a temporary resource that is created from a gold master image automatically and on demand. This basic cloud automation capability makes traditional patching redundant and fast provisioning extremely easy. It is an important consideration that changes some basic security deployment perceptions when moving from traditional infrastructure to the cloud.

The IaaS Management Market: Evolution, Vendors and More

A lot has already been said about the false cloud use where the IaaS platform utilized as an hosting extension of the IT organization’s data center and not taking advantage of the elasticity benefits to generate a cost effective and scalable IT operation. Using the public IaaS whether it is Amazon, Rackspace or any other vendor means using a highly dynamic environment which presents an increasing complexity hence loss of control. Checking the list below I can say that cloud (including all its layers IaaS, PaaS and SaaS) control basically contains the same aspects as the good old system management.

What is “System management” ?

Developers are from Mars

The three layers of cloud computing IaaS, PaaS and SaaS occupy the headlines with significant capabilities undergo continuous improvement to host services in the cloud. This growing market is slowly changing so that offered services will become generic. The current evolving struggle is the deployment and management of SaaS applications in the cloud, Gartner calls this cloud market portion SEAP (Software Enabled Application Platforms). We will dare to say that developers are from Mars and cloud providers from Venus, let us explain in detail why.

SaaS application developer builds the application architecture structure including the database system, the business logic and the user Interface. The software developer (or the SaaS vendor for that matter) invests on building these main three infrastructure cornerstones in order to bring life to the business idea and launch a new on-line service.

Hybrid Cloudonomics – Part 2


The first part of Weinman’s lecture discussing the basic “go to the cloud” and demonstrating cloud environments’ loads of different corporations’ web applications. In this part we will bring 6 scenarios presented by Weinman, each includes a brief analysis and proof of its cost and benefits.

First lets start with several assumptions and definitions:
> > > 5 Basic assumptions Pay-per-use capacity model:

  1. Paid on use – Paid for when used and not paid for when not used.
  2. No depend on time – The cost for such capacity is fixed. It does not depend on the time or use of the request.
  3. Fixed unit cost – The unit cost for on-demand or dedicated capacity does not depend on the quantity of resources requested (you don’t get discount for renting 100 rooms for the same time).
  4. No other costs – There are no additional relevant costs needed for the analysis.
  5. No delay – All demand served without any delay.
