Open source cloud adoption is growing, with 30% of respondents currently using an open source cloud in 2012, up from 17.2% in 2010, resulting in a 72% growth rate. Security, lack of in-house skills, lack of support and maturity were cited as the top four reasons for not choosing an open source cloud solution. The key attributes of cloud computing include shared/pooled resources, broad network access, on-demand self-service, scalability and elasticity, and usage-based metering. Open source investments should be analyzed with a full return on investment to address potential cost savings and increased business value.

Make Some Graphs and
• 99% of Global 2000 Enterprise would use
Open Source Software [OSS] by 2016
• Upward trend with 75% more companies
using OSS compared to 2010
• 70 percent of new enterprise Java
applications will be deployed on an open
source Java application server by the end
of 2017
• Open source software tools will continue
to erode revenue for some AD categories
in design, testing and Web development

8. Five Key Cloud Attributes:
1. Shared / pooled resources
2. Broad network access
3. On-demand self-service
4. Scalable and elastic
5. Metered by use

9. Shared / Pooled Resources:
• Resources are drawn from a common pool
• Common resources build economies of scale
• Common infrastructure runs at high efficiency

10. Broad Network Access:
• Open standards and APIs
• Almost always IP, HTTP, and REST
• Available from anywhere with an internet
connection

11. On-Demand Self-Service:
• Completely automated
• Users abstracted from the implementation
• Near real-time delivery (seconds or minutes)
• Services accessed through a self-serve
web interface

12. Scalable and Elastic:
• Resources dynamically-allocated between users
• Additional resources dynamically-released when
needed
• Fully automated

13. Metered by Use:
• Services are metered, like a utility
• Users pay only for services used
• Services can be cancelled at any time

ComputingComputing
In the cloud computing stack, there are three basic layers
that together create cloud environment. They are:
1.Infrastructure as a Service(IaaS)
2.Platform as a Service (PaaS)
3.Software as a Service (SaaS)
