Oracle Cloud Infrastructure (OCI) provides a comprehensive set of infrastructure services that enable you to build and run a wide range of applications in a highly available, secure, and scalable environment. Below are the various components of OCI infrastructure:
These are some of the key components of the Oracle Cloud Infrastructure (OCI) that enable you to build and manage your cloud infrastructure and application
1. Regions: A region is a localized geographic area composed of one or more availability domains. Regions are isolated from each other, and they are independent of each other in terms of fault tolerance and availability. Each region contains multiple data centers called availability domains. 2. Availability Domains (AD): An availability domain is a standalone, independent data center within a region. Availability domains are isolated from each other, with their own power, cooling, and networking infrastructure. This isolation enhances fault tolerance and availability. OCI services deployed within a region are designed to be resilient to failures within an availability domain. 3. Virtual Cloud Network (VCN): A VCN is a customizable, private network within OCI where you can launch your compute instances, block storage, and other resources. It is logically isolated from other virtual networks in the OCI environment, providing you with control over your network settings, such as IP addressing, route tables, and gateways. 4. Subnets: Subnets are subdivisions of a VCN and represent segmented portions of your network. You can divide a VCN into one or more subnets to host different types of resources. Subnets can be public or private, depending on whether they have internet connectivity. 5. Compute Instances: Compute instances, also known as virtual machines (VMs), are virtualized computing environments where you can run your applications. OCI offers various types of compute instances, including generalpurpose, highperformance, and GPU instances, suited for different workload requirements. 6. Block Storage: OCI provides block storage services for storing persistent data. Block volumes can be attached to compute instances as additional disks to provide scalable and highperformance storage. 7. Object Storage: OCI Object Storage is a highly scalable and durable storage service for storing unstructured data, such as documents, images, and videos. It provides a costeffective solution for storing and retrieving large amounts of data. 8. Networking Services: OCI offers a variety of networking services, including load balancers, DNS, VPN, and FastConnect, to enable secure and efficient communication between resources within your VCN and with external networks. 9. Database Services: OCI provides fully managed database services, including Oracle Autonomous Database, MySQL, and NoSQL Database, to support different types of database workloads. 10. Identity and Access Management (IAM): IAM is a centralized service for managing user access and permissions in OCI. It enables you to define and enforce security policies, roles, and permissions to control who can access which resources and perform specific actions. 11. Security Services: OCI offers a range of security services, such as Web Application Firewall (WAF), Key Management, and Security Zones, to protect your applications and data from security threats. 12. Monitoring and Management Tools: OCI provides monitoring, logging, and management tools, including OCI Monitoring, Logging, and Resource Manager, to help you monitor, troubleshoot, and manage your resources effectively. These are some of the key components of the Oracle Cloud Infrastructure (OCI) that enable you to build and manage your cloud infrastructure and application
