Virtualization

 Virtualization is a technology to run multiple same or different operating systems which is completely isolated from each other.

Ex: Run both Windows and Linux on the same machine.

• Virtualization offers major savings in data center operations.

• Virtualization makes possible significant reductions in the costs of managing data centers, with simplification of systems management tasks.

• Virtualization offers back-up and increased redundancy for delivery of high performance and high availability services.

• Virtualization is a step in the direction of “cloud computing”.

• Centralized management

Virtualization and Cloud Computing

• Virtualization is a technology where as Cloud Computing is a service.

• No virtualization then there is no Cloud Computing.

• Cloud Computing is built on top of Virtualization.

Hypervisor

Hypervisor is a software layer sits between Hardware and OSes which will interact with hardware and resources and provide an interface to share the available resources to virtual containers.

Sprint Burndown At a Sprint-level, the burndown presents the  easiest way to track and report status  (the proverbial  Red / Amber / Green ), i.e., whether your Sprint is on or off-track, and what are the chances of meeting the Sprint goals. The burndown chart – when used right – can provide  near-real time updates  on Sprint progress. “If your team do it right, then they would take in just the right amount of work into a sprint.” At the beginning of a Sprint, the Scrum team perform Sprint Planning and agree to take on development work worth a certain number of Story points. This forms the basis for the Sprint Burndown chart. The total story points agreed at the beginning of the sprint make up the y-axis, and the individual dates in the Sprint make up x-axis. If your team do it right, then they would take in just the right amount of work into ...
