Cloud


Centralizes Computing and Storage in a physically remote location from the User. It requires network connectivity to access and utilize data.


 

The Cloud brings together an on demand shared infrastructure of servers, storage, applications, and services. It requires access to Network/Internet connectivity and enough bandwidth to limit latency and enable seamless use.

The major benefits of Cloud are:  

  • -Lower Capex
  • -Faster Speed to Market
  • -Resource savings of staff, power and space which are shared across multiple users
  • -Elastic Expansion, easier to scale and accommodate spikes in demand traffic
  • -Measured Usage, pay as you go
  • -Accessible from Mobile, Desktop, Tablet and other devices

2 major Drawbacks to the Cloud are:

  • 1. The Cloud is useless without the Network 

Example: Credit card purchases fail to authorize when the network is down

Example: Slow speed may make videos unwatchable or take hours to download

2. 3rd party dependent for adds, moves and changes 

Consumer Applications

  • Storage-Google Drive, Microsoft One Drive,
  • Software Applications-Microsoft Online (Word, Excel), Quicken, Turbo Tax
  • Communications-Gmail, Yahoo Mail, Vonage
  • Entertainment-iTunes, Netflix, Youtube
  • Social Media-Facebook, Instagram

3 Types of Clouds 

 

SaaS Software as a Service is the licensing of software that is not downloaded to the device but accessed via a network and a remote host. Sometimes an App provides easy access.The business model is either subscription, metered or advertising supported. It is a One to Many delivery platform.

Key Attributes:

  • -All software is centralized Upgrades and Patches are managed remotely. The user does not need to be involved. Often Transparent to the end user.
  • -Internet access and appropriate speed necessary.
  • -API’s (Application Programming Interfaces) allow seamless integration with multiple software programs.

Considerations:

  • o-Basic apps such as email, word processing, accounting and human resources are generally adopted via SaaS as the subscription model provides
  • o-Project long or short term.
  • o-Is the App Mobile?
  • o-Real Time Processing Required? Transactional? Volume?
  • o-Regulatory consideration of Privacy?
  • o-Is there excess capacity on existing infrastructure?

Infrastructure as a Service is the virtualization of hardware and software to enable companies to host and store their applications as if they were resident on their own systems. Amazon (AWS), Google, and Microsoft (Azure) are leaders in this area.

Key Benefits:

  • Utility Pricing Model, Pay for Consumption
  • Dynamic Scaling
  • Shared Hardware
  • GUI and Self Provisioned

PaaS Platform as a Service enables applications developers and coders to quickly access, execute and manage applications without having to purchase and maintain expensive infrastructure such as Data Center Space, Storage, Cooling, and Operating Systems. and It is utilized for App Development and is particularly effective in team environments and when working with multiple companies. Google’s App engine and Microsoft Azure are leaders.

Considerations:

  • Does it use a proprietary language that would effect if it was portable? Does the platform lock the user in and would the development process be impacted in the case of portability?
  • How many developers will be involved? Same company?
  • Security
  • Will the testing and deployment process be automated?
  • Storage costs and limits
  • How fast to market must the application be developed?
