An Oracle Cloud Infrastructure region is a localized geographic area that contains one or more data centers, called availability domains. Regions are independent of other regions, and vast distances can separate them (across countries or even continents).

Availability domains are standalone, independent data centers within a region. The physical resources in each availability domain are isolated from the resources in the other availability domains, which provides fault tolerance. Availability domains don’t share infrastructure such as power or cooling, or the internal availability domain network. So, a failure at one availability domain is unlikely to affect the other availability domains in the region.

Oracle Cloud Infrastructure Web Application Firewall (WAF) is a cloud-based, payment card industry (PCI) compliant, global security service that protects applications from malicious and unwanted internet traffic. WAF can protect any internet-facing endpoint, providing consistent rule enforcement across a customer's applications.

A VCN is a customizable, software-defined network that you set up in an Oracle Cloud Infrastructure region. Like traditional data center networks, VCNs give you complete control over your network environment. A VCN can have multiple non-overlapping CIDR blocks that you can change after you create the VCN. You can segment a VCN into subnets, which can be scoped to a region or to an availability domain. Each subnet consists of a contiguous range of addresses that don't overlap with the other subnets in the VCN. You can change the size of a subnet after creation. A subnet can be public or private.

The internet gateway allows traffic between the public subnets in a VCN and the public internet.

The service gateway provides access from a VCN to other services, such as Oracle Cloud Infrastructure Object Storage. The traffic from the VCN to the Oracle service travels over the Oracle network fabric and never traverses the internet.

A NAT gateway enables private resources in a VCN to access hosts on the internet, without exposing those resources to incoming internet connections.

Object storage provides quick access to large amounts of structured and unstructured data of any content type, including database backups, analytic data, and rich content such as images and videos. You can safely and securely store and then retrieve data directly from the internet or from within the cloud platform. You can seamlessly scale storage without experiencing any degradation in performance or service reliability. Use standard storage for "hot" storage that you need to access quickly, immediately, and frequently. Use archive storage for "cold" storage that you retain for long periods of time and seldom or rarely access.

The Oracle Cloud Infrastructure File Storage service provides a durable, scalable, secure, enterprise-grade network file system. You can connect to a File Storage service file system from any bare metal, virtual machine, or container instance in a VCN. You can also access a file system from outside the VCN by using Oracle Cloud Infrastructure FastConnect and IPSec VPN.

The bastion host is a compute instance that serves as a secure, controlled entry point to the topology from outside the cloud. The bastion host is provisioned typically in a demilitarized zone (DMZ). It enables you to protect sensitive resources by placing them in private networks that can't be accessed directly from outside the cloud. The topology has a single, known entry point that you can monitor and audit regularly. So, you can avoid exposing the more sensitive components of the topology without compromising access to them.

The Oracle Cloud Infrastructure Compute service enables you to provision and manage compute hosts in the cloud. You can launch compute instances with shapes that meet your resource requirements for CPU, memory, network bandwidth, and storage. After creating a compute instance, you can access it securely, restart it, attach and detach volumes, and terminate it when you no longer need it.

Oracle Cloud Infrastructure Data Flow is a cloud-based, serverless platform that allows you to create, edit, and run Spark jobs at any scale without the need for clusters, an operations team, or highly specialized Spark knowledge. During runtime, Data Flow obtains the application source, creates the connection, retrieves the data, processes it, and writes the output to Oracle Cloud Infrastructure Object Storage.

Oracle Cloud Infrastructure Container Engine for Kubernetes is a fully managed, scalable, and highly available service that you can use to deploy your containerized applications to the cloud. You specify the compute resources that your applications require, and Container Engine for Kubernetes provisions them on Oracle Cloud Infrastructure in an existing tenancy. Container Engine for Kubernetes uses Kubernetes to automate the deployment, scaling, and management of containerized applications across clusters of hosts.

Oracle MySQL Database Service is a fully managed Oracle Cloud Infrastructure (OCI) database service that lets developers quickly develop and deploy secure, cloud native applications. Optimized for and exclusively available in OCI, Oracle MySQL Database Service is 100% built, managed, and supported by the OCI and MySQL engineering teams.

Oracle MySQL Database Service has an integrated, high-performance analytics engine (HeatWave) to run sophisticated real-time analytics directly against an operational MySQL database.
