cloud computing in OCI

Hi Friend  , Hope you are doing well .  

Today i am with new and very popular topic called Cloud computing . As we know now a days cloud, cloud computing , VCN , OCI words are very popular because  database and applications are moving to cloud . 

cloud providers like oracle, Microsoft , Amazon are ready to serve your database management on rent basis and that's  the reason cloud called pay as you go Model . it means just pay  for those how much you need it to manage db  or infrastructure.  

so Friends what is cloud Computing  

cloud computing is on demand delivery of IT resources over internet as pay as you go model.

so as a client no need to invest money for IT infrastructure like hardware , server , networking , cpu , database , Application etc.
just login to cloud with your authentication take subscription from cloud  providers and use it then pay per  your bill .

Why cloud :  ----

there are many advantage  to move towards cloud  from on premises :---

1) Capital Expenses ---- it will reduce capital expenses like  no need to pay for server, cpu and infra .

2) pay as you go ----- every cloud vendor provides monthly billing so you can pay as needed like you can use 10 cpu in high load or 1 cpu in low load as per req can pay for that only.

3) global ---- every cloud vendor provides global data center like they have region and availability domain concept and you can keep your database and Application in that region which ever nearest or fusible to you .

4) Scalable ---- cloud technology is very much scalable in terms of infra-structure .  whenever you want you can scale-up or scale-down your infra as per your use.

What  are the cloud computing services 

Basically we three type of cloud computing services  . type depend on our usage  like what exactly we  are using 

ex few organisation only needed software and they have their own infrastructure and programming i.e platform  .  few needed infra as well  so on that cloud providers have divided cloud in 3 parts

1) Infrastructure as a service  ( Iaas)  -----   it provides vertualised infrastucture on internet and

client can use cpu,server, hardware , ram etc as how much they have requirement.

2) Plateform as a service (Paas) ------  Provides Plateform for Application devolopement .

3) Software as a service (Saas) -----  Provider software on rent basis , it means all infra and plateform would be with cloud provider and you can only use it . managing part by them .


you can login on    "  cloud.oracle.com "   or create a user account  go to payment page provide your credit card details  it will deduct 1 Dollar ($) of amount and it will  return you the same amount in your card . basically its a free account from oracle for one month period , and can learn as much as yo can .

if any doubt regarding this , please comment and ask , I will reply you .
