Many midsize corporations have enterprise solutions based on legacy systems created more than a decade ago with no strategy or architecture in mind. From a time where sustainable and ecosystems didn’t even exist. Today, those systems became a monster hard to deal with and, extremely high to maintain. Corporations need to make a decision now and chose the appropriate technology to update or rebuild their solutions with customers on mind.

When one looks at all the wastes, defects has to be the most obvious one. The cost and repercussions of finding defects varies depending on where in the cycle they’re found. Defects found early on in the development life-cycle are way less costly to resolve than defects found later on in the cycle; the most expensive being when applications are already in-production.
Additionally, depending on when the defects are found, defects can and do trigger other wastes like task switching, relearning etc.

Every time a project is initiated there is no understanding, time-consuming effort to write down all foreseeable tasks or requirements. Usually, a project writes down what is obvious, which is almost always more than enough for a first sprint. The Product Backlog is then allowed to grow and change as more is learned about the product and its customers.

Basically, moving to the cloud it shouldn’t impact your architecture with many changes as we believe. If your platform has a well design architecture based on independent layers (UI, Logic, Data, etc), adapting to work in a Cloud environment only mean to add a new layer of virtual environments to your n-tiers environment. Moving to the Cloud only become a problem when solutions don’t have a solid and well designed architecture and basically they are pushed back at the moment to adapt to this new age of technology.

I have talked about virtualization and also about Cloud Computing but, what options are available to implement cloud computing Infrastructure implementations? Well, that is simple!
Hardware technologies for virtualization (hypervisor)
Hypervisor Virtualization has a layer (usually a thin Linux kernel shown here as a hypervisor or standard OS) that is loaded directly on the bare server. To allocate hardware and resources to the virtual machines (VMs), all hardware on the server must be virtualized. The next layer up shows each chip, board, etc. that must be virtualized so that it can be assigned to the VMs. Once in the VM itself, there is a complete copy of an operating system and finally the application or workload.
