Cloud Computing Services


What is Cloud?

  • Cloud refers to a network or internet, which is present at certain place which is accessible from any location over public network or private network
  • Cloud Computing refers to manage, configuring, and accessing the applications online. It offer online data storage, compute, network infrastructure and application which delivered as a network services.
  • Cloud computing tends to separate infrastructure with business, whereas terms "infrastructure" refer to hardware, networking, and software which managed as one entity. And terms "Business" refers to procedural workflow, strategic enforcement, etc

Deployment Examples

  • Social networking : Facebook, Instagram, LinkedIn, etc.
  • Data sharing / collaboration : Email, Dropbox, etc.
  • Education : Quipper, Smart Campus, E-Learning, E-Library, etc.
  • Business : Office application : Online shop portal, Google doc, Personal / Corporate                      Websites, etc.
  • HPC for limited duration : Efficiency for massive computing workload

Cloud Usage for Enterprise

  • Disaster Recovery as Service (DRaaS) : Managed replication hasting services of physical or virtual servers to provide failover in the event of catastrophe.
  • Backup as a Service (BaaS) : Managed data backup to provide data restoration
  • Data as a Service (DaaS) : Managed data sharing & collaboration with ease.

Advantages & Disadvantages

Advantages :
  • Lower compute resources cost
  • Flexible performance improvement
  • Reduced software / hardware cost
  • Manageable infrastructure update
  • Relieve storage capacity limitation
  • Increased data reliability
  • Universal data access
  • Easier group collaboration
  • Device independence

Disadvantages :
  • Requires a constant internet connection
  • Features might be limited
  • Performance / speed concern
  • Data / System contingency plan
  • Data security concern
  • Doesn't work with low speed connection

Fear Uncetainty Doubt (FUDs)
  • Performance, latency, etc : Predetermined performance, fully customizable.
  • Security : Lots of security options, could be deployed as necessary similar to regular data center
  • Availability : Devices suppose to be connected to internet, in fact internet is available almost everywhere
  • Confidentiality : Trusted agreement, NDA document Audited, etc.
