Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as-a-Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs.

The serverless and elastic architecture of Oracle Functions means there's no infrastructure administration or software administration for you to perform. You don't provision or maintain compute instances, and operating system software patches and upgrades are applied automatically. Oracle Functions simply ensures your app is highly-available, scalable, secure, and monitored. With Oracle Functions, you can write code in Java, Python, Node, Go, and Ruby (and for advanced use cases, bring your own Dockerfile, and Graal VM). You can then deploy your code, call it directly or trigger it in response to events, and get billed only for the resources consumed during the execution.

Here is the official list of all industry standards that OCI complies with : https://www.oracle.com/in/cloud/cloud-infrastructure-compliance/

There are two types of DB systems on virtual machines:

· A 1-node virtual machine DB system consists of one virtual machine.

· A 2-node virtual machine DB system consists of two virtual machines. (RAC)

A virtual machine DB system database uses Oracle Cloud Infrastructure block storage instead of local storage. You specify a storage size when you launch the DB system, and you can scale up the storage as needed at any time.

For 1-node virtual machine DB systems, Oracle Cloud Infrastructure provides have a "fast provisioning" option that allows you to create your DB system using Logical Volume Manager as your storage management software.

Oracle Cloud Infrastructure offers single-node DB systems on either bare metal or virtual machines, and 2-node RAC DB systems on virtual machines. If you need to provision a DB system for development or testing purposes, then a special fast provisioning single-node virtual machine system is available.

You can manage these systems by using the Console, the API, the Oracle Cloud Infrastructure CLI, the Database CLI (DBCLI), Enterprise Manager, Enterprise Manager Express, or SQL Developer.

Budgets and Compartment Quotas are two features that can be used to manage cost in an OCI tenancy. Budgets allow you to track and control your spending on OCI services by setting spending thresholds and getting alerts when you exceed them. Compartment Quotas allow you to limit the amount of resources that can be created or used in a compartment by setting quotas on specific resource types or metrics.

An availability domain is a part of a region. A region is a localized geographic area composed of one or more availability domains. An availability domain is one or more data centers located within a region that have fault-tolerant power and network connectivity. Availability domains are isolated from each other within a region, which provides protection from failures that affect multiple data centers at once.

A shape is a template that determines the number of CPUs, amount of memory, and other resources that are allocated to an instance.

The network bandwidth is directly proportional to the number of OCPUs in the instance shape!

Explanation

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 your Virtual Cloud Network (VCN). You can also access a file system from outside the VCN using Oracle Cloud Infrastructure FastConnect and Internet Protocol security (IPSec) virtual private network (VPN).

Large Compute clusters of thousands of instances can use the File Storage service for high-performance shared storage. Storage provisioning is fully managed and automatic as your use scales from a single byte to exabytes without upfront provisioning.

The File Storage service supports the Network File System version 3.0 (NFSv3) protocol. The service supports the Network Lock Manager (NLM) protocol for file locking functionality.

Oracle Cloud Infrastructure File Storage employs 5-way replicated storage, located in different fault domains, to provide redundancy for resilient data protection. Data is protected with erasure encoding.

The File Storage service uses the "eventual overwrite" method of data eradication. Files are created in the file system with a unique encryption key. When you delete a single file, its associated encryption key is eradicated, making the file inaccessible. When you delete an entire file system, the file system is marked as inaccessible. The service systematically traverses deleted files and file systems, frees all the used space, and eradicates all residual files.

Use the File Storage service when your application or workload includes big data and analytics, media processing, or content management, and you require Portable Operating System Interface (POSIX)-compliant file system access semantics and concurrently accessible storage. The File Storage service is designed to meet the needs of applications and users that need an enterprise file system across a wide range of use cases, including the following:

OCI logs are encrypted in three ways: in-flight, disk-level, and archive. OCI logs are encrypted in-flight, that is, while they are in the process of being ingested into OCI Logging; after the logs are in the system, they are encrypted with disk-level encryption for commercial environments; and logs are also encrypted when they are archived, and while in storage
