Characteristics of cloud computing :

  1. Users computer resources ko monitor and manage kr sakte hai bina human administration ki help se.
  2. Computer services broad network pe access ki ja sakti hai.
  3. Koi jarurat wali cheez aur bhot sare apps and jo ki paise pay karta ho kisi software ke liye (one who pays a fee in return) ke saath share kr sakte hai and isey “resource pooling” kehte hai.


Layers of cloud computing :

Client, application; platform and infrastructure. Sometimes server ko bhi as a layer consider kia jata hai. Kyunki wo hardware and software products deta hai. Jo Ki sirf cloud services ko deliver karne ke liye design hui hai.

  1. Client -It consists of hardware and software Jo Ki cloud services ko access karte hai. Client 2 type ke hote hai: thick client and thin client.
  2. Application layer or software as a service (SaaS ) -Internet based applications host Ki jaati hai cloud pe and services offer Ki jaati hai users ko. SaaS is offered by companies jaise Ki Google, Microsoft, zoho, salesforce, etc.
  3. Platform as a service(PaaS ) -applications ko design, develop, built and test karne ke liye platform provide karta hai cloud. PaaS providers predefined combination dede hai. Os and application servers ka ,jaise Ki LAMP platform ( Linux, apache, MySql and PHP ), ruby ,etc. PaaS examples: google’s app engine, force.com, etc.
  4. Infrastructure as a service ( IaaS) – workload ko handle karne ke liye storage system, networking equipment, data centre space, etc offer Ki jaati hai. Example of IaaS – amazon, GrId, 3 Tera.


Deployment models of cloud:

  1. Private clouds – single organisation ke use ke liye clouds
  2. Public clouds – shared basis pe multiple organisations ke use ke liye clouds Jo Ki third party service provider manage krta hai
  3. Community clouds – group of related organisations ke use ke liye, jaise Ki EK region Ki saare universities ke liye EK common cloud.
  4. Hybrid clouds – jab EK single organisation private and public dono cloud ko adopt kre dono ka advantage uthane ke liye.

Issues in cloud computing jinhe sudharna hai

  1. Privacy – data privacy available Nhi hai. Service provider data ko alter and even delete bhi kar deta hai.
  2. Compliance – *to comply with regulations * users community ya hybrid mode adopt kare toh wo bahot expensive hota hai.
  3. Security – users ka data secure Nhi hota kyuki cloud based products may be user ka data kia third party se share kre.
  4. Abuse – ye dhyan rakha jana chaliye Ki client cloud services ko GALAT use ke liye Nhi le rha ,example : password cracking ..2009 mai EK banking trojan ne illegally amazon mi service ko control channel banake software updates Ki thi Jesse Ki PCs malware se infect ho gye the.

Hosting companies and servers ko dhyan dena chahiye aur in issues ko solve karna chahiye.
