Oracle Cloud Identity Domain – Concepts

Published December 24, 2016 By Brijesh Gogia

Identity domain is synonymous to  tenant concept in Oracle Cloud. Oracle Cloud is a multitenant system, and each client is a tenant in the big Oracle Cloud system. It is just like the tenants of a building. So, an identity domain represents a slice of the Oracle Cloud, provisioned for a cloud tenant according to Client’s demand.

An Oracle Cloud service account is a unique customer account that can have multiple cloud services of different service types. Also an account can contain multiple Identity Domains, and each Identity Domain can contain multiple Database Cloud Services.  For example, you could have three different cloud services, such as Java Cloud Service, Database Cloud Service, and Infrastructure as a Service (IaaS) as part of a single Oracle Cloud service account.

Although an account can have one or more Identity Domains, but each Domain is separate and distinct.   Users in an identity domain can be granted different levels of access to each service associated with the domain.

Cloud Computing – Basic Concepts

Published December 23, 2016 By Brijesh Gogia

BASIC DEFINITION

Cloud computing which is usually referred to as simply “the cloud,” is the on-demand delivery of compute power, database storage, applications, and other IT resources through a cloud services platform via the internet with pay-as-you-go pricing.

Key word here is “on-demand”. You demand that you need some resource (CPU/Storage/Database/Platform/Apps etc) and you get it instantly by as simple as pressing couple of keys in your web hosted Cloud Panel.

Traditionally, you used to first order these resources through defined channels before started using them. Example, in your traditional setup, as a DBA if you required another 1 TB of disk for your database you may have to go to your UNIX Admins which in turn used to go to storage admins and Storage admins used to carve out the right size disk or order new capacity from the storage company. UNIX Admins then partition and extend the LV and then at last you will get the disk to increase your database size. This is very simple example of traditional system but explains that it takes resource. time and effort to get such repetitive things done. Cloud computing helps in overcoming such limitations.
