The term “Cloud” is used to denote the sharing of computing resources and data across a network between multiple sites. Data and applications can be hosted centrally and accessed over the internet, which eliminates the need for local servers and other hardware to accomplish basic tasks such as processing or storing data. This helps users in cutting down the costs associated with purchasing, deploying, and maintaining local infrastructure.
In simple terms, Oracle cloud is a set of on-demand services from Oracle that enable developers to rapidly assemble an Enterprise Resource Planning (ERP) system for any line of business or industry on a pay-as-you-go basis. The Oracle Cloud will provide the security, scalability, and reliability that Oracle customers have come to expect.
Components of Cloud Oracle:
Cloud Oracle uses the following components.
1- Oracle DBaaS (Database as a Service) on Cloud:
A secure, scalable enterprise-grade relational database service for consolidating and managing your databases in Oracle Cloud. You can either deploy new databases or import existing Oracle Databases using the Data Pump Import/Export tool to provision your Database Instances.
2- Oracle REST Data Services (ORDS) on Cloud:
The open-source development toolkit is used for building and deploying Web-based data transfer applications. ORDS is designed as a drop-in replacement for Web-based middleware such as Apache WSRP, Microsoft ASP .Net, and IBM Data Studio Gateway allowing you to easily integrate applications to access Oracle Databases on Cloud.
3- Oracle SOA Cloud Service on Cloud:
An infrastructure for service providers and developers to easily build, host, run and manage SOA composite applications in the cloud. Managed by the Oracle Enterprise Manager (OEM) product family, it provides a Web-based portal for working with SOA applications and services.
4- Oracle REST Data Service on Cloud:
The open-source development toolkit for building and deploying Web-based data transfer applications. It is designed as a drop-in replacement for Web-based middleware such as Apache WSRP, Microsoft ASP .Net, IBM Data Studio Gateway allowing you to easily integrate applications to access Oracle Databases on Cloud.
5- Virtual Machine:
A virtual machine (VM) is a program that acts as a computer and executes commands, as with real computers. You can use VM images available in the public catalog to set up and execute database servers, JAVA EE application servers, WebLogic application servers, and other software on Oracle Cloud Infrastructure. The VM programs can be executed remotely, and their facilities are similar to the hardware equipment in a real computer.
An image (virtual disk or virtual appliance) is an operating system and application environment installation package for VM instances. You can deploy pre-configured images from the public catalog to your VMs.
7- Access to Data Services:
You can access Application Services, Data Services, Identity Management Services, and VM Services included in the Oracle Cloud by using public Internet connections. If you use Virtual Private Network (VPN) services to securely connect your corporate network with Oracle Cloud Infrastructure, you can also access these services over private connections.
Oracle Cloud Infrastructure is a SaaS tool that lets you manage your cloud as well as provide services to users. It helps you to easily deploy VMs, images and create an infrastructure for cloud services. Oracle Cloud Infrastructure also has APIs that help you integrate it with other tools, making it a really useful tool for any developer who wants to manage his cloud infrastructure.
