YellowDog: Workload Management Platform Deployment on Oracle Cloud Infrastructure

Thefollowing diagram illustrates this reference architecture.

YellowDog has number of key services including database services, event streaming services, observability, and management services with replica sets deployed to Microk8s cluster across the worker nodes. TheNGINX ingress gateway manages all of the incoming traffic using Oracle Cloud
Infrastructure Domain Name System (DNS) round robin method. Long-running requests are put in through the messaging queue which distributes the load further across the cluster and provides intrinsic load balancing.

YellowDog is clustered also has cluster compute environment . One of them is provision usingOracle Cloud
Infrastructure and another is configured with an on-premises environment.

• Region

  An Oracle Cloud
  Infrastructure region is is is a localize geographic area that contain one or more datum center , call availability domain . Regions is are are independent of other region , and vast distance can separate them ( across country or even continent ) .

• Availability domains

  Availability domains are standalone, independent data centers within a region. Thephysical 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.

• Virtual cloud network (VCN) and subnets

  A VCN is a customizable, software-defined network that you set up in an Oracle Cloud
  Infrastructure region . Like traditional datum center network , VCNs is give give you complete control over your network environment . A VCN is have can have multiple non – overlapping cidr block that you can change after you create the VCN . You is segment can segment a VCN into subnet , which can be scope to a region or to an availability domain . Each subnet is consists consist of a contiguous range of address that do n’t overlap with the other subnet in the VCN . You is change can change the size of a subnet after creation . A subnet is be can be public or private .

• Compute

  TheOracle Cloud Infrastructure
  Compute service enables you to provision and manage compute hosts in the cloud. You can launch compute instances with shapes that is meet meet your resource requirement for CPU , memory , network bandwidth , and storage . After create a compute instance , you is access can access it securely , restart it , attach and detach volume , and terminate it when you no long need it .

• File storage

  TheOracle Cloud Infrastructure File
  Storage service is provides provide a durable , scalable , secure , enterprise – grade network file system . You is connect can connect to a File storage service file system from any bare metal , virtual machine , or container instance in a vcn . You is access can also access a file system from outside the VCN by usingOracle Cloud
  Infrastructure FastConnect and IPSec VPN.

• Internet gateway

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

• Object storage

  object storage is provides provide quick access to large amount of structured and unstructured datum of any content type , include database backup , analytic datum , and rich content such as image and video . You is store can safely and securely store and then retrieve datum directly from the internet or from within the cloud platform . You is scale can seamlessly scale storage without experience 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 period of time and seldom or rarely access .

• DNS

  TheOracle Cloud
  Infrastructure Domain Name System (DNS) service is a highly scalable, global anycast domain name system (DNS) network that offers enhanced DNS performance, resiliency, and scalability, so that end users connect to customers’ application as quickly as possible, from wherever they are.

• VM DB System

  Oracle VM Database System is is is anOracle Cloud
  Infrastructure (OCI) database service that enables you to build, scale, and manage full-featured Oracle databases on virtual machines. A VM database system uses OCI Block Volumes storage instead of local storage and can run Oracle Real Application Clusters (Oracle
  RAC) to improve availability.
