Oracle cloud is a cloud services environment that enable to build and run wide range of applications and services. Before study the core of oracle cloud infrastructure (OCI), it needs to discuss about the key terminology of OCI.

Region and Availability domain: A region is a localized geographical area and availability domain is one or more data centers in a region. A region includes one or more availability domains and availability domains are isolated with each one to avoid the failure effects of an availability domain to another.

Console: Console is the web user interface to manage all activities of OCI and access the OCI.

Tenancy: When you create your OCI account for your company, Oracle will create a tenancy. It is an isolated partition in OCI and you can administrate and organize your cloud works in the tenancy.

Compartments: Compartments give the facility to control the access of cloud resources. It is a collection of resources of cloud like instances, block volumes etc. Permission will be given by the administrator to groups to access the compartments. Compartments is a logical group and it filters the view for users.

Virtual Cloud Network (VCN): It is the usual network with gateways, subnets and other components of networking. You need to create at least one VCN before launch an instance.

Instances: An instance is a compute host running on OCI. You can utilize the machine by enhancing performance.

Image: An image is a blue print of a virtual hard drive that contain the operating system and other software services. When you needed to launch an instance you can define the characteristics by selecting the image.

Shape: In OCI, the shape specifies the number of CPU and amount of memory allocated for an instance.

Key pair: Key pair is an authentication mechanism in the OCI. It contains private key file and public key file and you need to upload the public key to OCI and keep the private key in your computer more secured way. The private key is like password for logging authentication.

Block volume: A block volume is a virtual disk and provides block storage space for OCI. It is like a physical hard drive for your computer. Simply you can attach a block volume for an instance by detaching from another without any data lost.

Object storage: It is another data storage mechanism in OCI and it store and manage data as objects. If you needed to store very large amount of data that does not change very frequently,better to store as object storage. Normally object storage includes data backups, file sharing and logs.

Bucket: A bucket can contain infinite number of objects and it is a large container.

What is Cloud Computing?

Cloud computing is an internet-based service in which large groups of remote servers are networked to allow centralized data storage, and online access to computer resources. It saves money and time for organizations other than using there own servers and infrastructure.

Main benefits for the organization using cloud computing are

Resources can be scale up or down to organizations requirement.

You only have to pay for what you use.

You can access your resources from any where any time with proper security.

Can add or remove services on demand.

You do not have to worry about disaster management or limited storage.

There are three main cloud service models

Infrastructure as a Service (IaaS).
Cloud infrastructure services, known as Infrastructure as a Service (IaaS), are made of highly scalable and automated compute resources. IaaS is fully self-service for accessing and monitoring things like compute, networking, storage, and other services, and it allows businesses to purchase resources on-demand and as-needed

Platform as a Service (PaaS)
Cloud platform services, or Platform as a Service (PaaS), provide cloud components to certain software while being used mainly for applications. PaaS provides a framework for developers that they can build upon and use to create customized applications. All servers, storage, and networking can be managed by the enterprise or a third-party provider

Software as a Service (SaaS)
Software as a Service, also known as cloud application services, represent the most commonly utilized option for businesses in the cloud market. SaaS utilizes the internet to deliver applications to its users, which are managed by a third-party vendor.

Amazon Web Services is the most popular service provider which uses all the cloud service models above.
