Cloud Computing Services

Contoh Cloud Services
Social media -> FB , IG, LinkedIn, etc
Data sharing / colllaboration -> Dropbox, email, gdrive,etc
Education -> Quipper, Smart Campus, E-Learning, etc
Business / Office Application -> Online shop portal, Google Doc, etc.
High Perfomance Computing for limitied duration -> Efficiency for massive computing workload
And many more -> Media streaming, entertainment, games, publishing, etc

Basic Concepts
Deployment Model
dibagi menjadi 3 jenis :
- Public Cloud
- Private Cloud
- Hybrid Cloud

Cloud Usage for enterprise
Disaster recovery as a service (DRaaS)
Managed replicatiob and hosting services of physical or virtual servers to provide failover in the event of catastrope
- with DRaaS, tthe time to return applications to production is reduced because data does not need to be restored over the internet.
Backup as a Service (Baas)
Managed data backup to provide data restoration
- with Baas, congtingency managemenet is streamlined witout painn point for data restoration spend and recoverability
Data as a servide ( Daas)
Managed data shareing & collaboration with ease
- Daas enable data sharing,

Kelebihan menggunakan cloud
- lower compute resources cost
- flexible perfomance improvemenet
- reduced software/hardware cost
- manageable infrastructure update
- relieve storage capacity limitation
- increased data reliabiltiy
- universal data access
- easier group collaboration
- device independence

Kekurangan menggunakan cloud
- requires a constant internet connection
- Featres might be limited
- Perfomance / speed concern
- Data / system contingency plan
- Data Security concern
- Doesn't work wth low-speed connection

Fear Uncertainty Doubt
Perfomace, latency , etc
- Predetermined perfomance, fully customziable
Security
- Lots of security optioins, could be deployed as necesaary similar to regular data center
Availability
- Devices suppose to be connected to internet, in fact internet is available almost everywhere
