Story points are used to measure the effort required to implement a story and is measure based on Size, Factorial, Squares or Fibonacci techniques. This is a random measure used by Scrum teams.

This is mainly done as we as humans and as managers are better at abstract terms. If we use hours as a way to size stories, then the managers in the room have questions, teams don’t immediately feel comfortable with hours…

Duration	Size	Factorial	Squares	Fibonacci
1 – 3 day	X Small	1  (1!)	1 – 12	1

Quick definition: Cloud Computing is an Internet based platform geographically distributed and developed to provide real-time scalable resources and provided “as a service” over the Internet to users who don’t need to have deep knowledge or expertise on technology infrastructure. The concept incorporates software as a service (SaaS), and other well-known technology trends.

As I mentioned earlier, Capability Maturity Model “CMMI” is a collection of best practices for the development and maintenance of both products and services. It is the application of process management and quality improvement concepts to software development and maintenance and, designed to guide in selecting improvement strategies by determining current maturity of the software process.

The CMMI is a collection of best practices for the development and maintenance of both products and services. It was developed to enhance and replace the use of multiple process models, while preserving the government and industry investments in process improvement. By combining multiple models into a single model, the CMMI has enabled the use of common terminology, components, appraisal methods, and training material across multiple disciplines. This, in turn, reduces the cost of establishing and maintaining process improvement efforts across the enterprise using multiple disciplines to deliver products or services. The CMMI currently covers systems engineering, software engineering, integrated product and process development, and supplier sourcing. The CMMI represents the consolidation of the following models:

As I promised this morning, these are a few lines to help on setting your intranet systems in the Cloud Computing enviroment. As you probably already noticed, it is all about infrastructure as a service, designed to make web-scale computing easier for developers.

Amazon EC2 (Amazon Elastic Compute Cloud): In simple words, is a collection of web services that provides resizable compute capacity in the cloud. It provides you with complete control of your computing resources and lets you run on Amazon’s computing environment.  Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing you to scale capacity, both up and down, as your computing requirements change. EC2 allow you to pay only for capacity that you actually use.
