Cloudy Internet
Open source software (OSS）
free access
free distribution
customised
software that is free and where anyone can look at and potentially modify the code
Linux
open source software system
Unix
OSX
customised
part of OSX - safety
Linux
millions - I cannot find anything wrong
source code for OSS products - openly shared
can be changed and redistributed by anyone
the internet has enabled OSS
In contrast to the practice of conventional software firms
intellectual property >> guarded secrets
never provide the source code
seen as a threat by some firms undermining their economic model
Enabler
LAMP!!!!!!!
Linux
Apache Web server software
MySOL database
Perl/Python/PHP
~~~powers many of sites visited each day from Facebook to YouTube
Why open source
Cost
Reliability
many eyes
Security
many eyes
Scalability
handle increasing workloads / to be easily expanded to manage workload increases
Agility and time to market
Examples of conventional VS open source software
IE
Chrome
Visio
Dia
Photoshop
Gimp
Dreamweaver
Quanta Plus
AutoCAD
FreeCAD
iTunes
Songbird
Windows
Linux
impact of OSS on IT market
• Lowers the cost of computing and makes computing options accessible to smaller firms
• Reliable, secure, and lowers computing costs for all users
• Diverts funds that can be used for other competitive initiatives and encouraging innovation
Business of Open Source
Vendors make money on OSS by selling support and consulting services
Industry’s evolution (standards competition)
Pre-Linux days - Almost every major hardware manufacturer made its own incompatible version of the Unix operating system
They had difficulty attracting third-party vendors to write application software
Now all major hardware firms run Linux resulting in a large, unified market attracting software developers
example << android
cloud computing
replacing computing with services provided over the internet
software as a service (Saas)
firm subscribes to a third-party software and receives a service that is provided online
profit model
monthly subscription
advertising
upgraded/premium version
compete with biggest names
salesforce.com - CRM provider
amazon web services
Benefits to users
Lower risk and financial risk mitigation
faster deployment times and variable operating expense
scalable systems
higher quality and service levels
remote access and availability
• Limits development to a single platform
• Tighter feedback loop
• Ability to instantly deploy bug fixes and product enhancements
• Lower distribution costs
• Greater accessibility
• Reducing software piracy
Risks
Dependence on a single vendor
Concern about the long-term viability of partner firms
Users may be forced to migrate to new versions:
Reliance on the Internet to access SaaS – stability and security issues?
where is the cloud
Data asset stored off-site may lead to security and legal concerns
Limited configuration, customization, and system integration options compared to packaged software or alternatives developed in-house
User interface of Web-based software is sometimes less sophisticated and lacks the richness of most desktop alternatives
Ease of adoption may lead to pockets of unauthorized IT being used throughout a firm
too couldy?
Installing a complex set of systems on someone else’s hardware is very difficult
Firms considering cloud computing need to do a thorough financial analysis
Firms should enter the cloud cautiously, particularly where mission-critical systems are concerned
Clouds and Tech Industry Impact
• Shifting to cloud computing modifies the margin structure for many in the computing industry: product revenue to service revenue, similar case for printer and cartridge?
• Microsoft Office is dropping in sale while Microsoft Office 365 is gaining momentum
IT worker, organization<< • Cloud computing can accelerate innovation
Future of the Internet – Internet of Things
• Vision of embedding low-cost sensors, processors, and communication into a wide array of products and the environment
– Allow a vast network to collect data, analyze input, and automatically coordinate collective action
