Network Security Groups (NSGs) and Security Lists (SLs) are two virtual firewall features that can be used for controlling traffic in an OCI Virtual Cloud Network (VCN).NSGs and SLs allow you to create stateful network filtering rules that allow or deny network traffic based on source and destination IP addresses, ports, and protocols5

NSGs are a subsequent feature designed for application components that have different security postures. NSGs are a set of security rules that you can apply to a set of VNICs in a VCN. NSGs are associated with VNICs, not subnets. You can use NSGs to implement a network security policy at the level of individual VNICs or a group of VNICs.For example, you can use NSGs to control traffic between tiers of an application deployed in a VCN5

SLs are the original virtual firewall feature from the Networking service. SLs are a set of security rules that you apply to a subnet in a VCN. SLs are associated with subnets, not VNICs. You can use SLs to implement a network security policy at the level of the subnet.For example, you can use SLs to control traffic between subnets in a VCN5

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 usingLogical Volume Manageras your storage management software.

Oracle Cloud Infrastructure offers single-node DB systems on either bare metal or virtual machines, and 2-nodeRAC DB systemson virtual machines. If you need to provision a DB system for development or testing purposes, then a specialfast provisioningsingle-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.

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.

Theserverlessandelasticarchitecture 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.
