Remote Cloning

OCI Golden Gate

Data Pump

Data Guard

Unplug and Plug Database

To allow users to lease IP addresses directly from Oracle's IP address pool

To provide users with additional Oracle-owned IP addresses for their OCI resources

To facilitate the use of externally owned IP address space alongside OCI resources

To enable users to bring their own physical servers into OCI data centers

It compresses backup data before transferring, thereby expediting the migration process

It automates the migration process by transferring applications between regions

It ensures real-time data synchronization during migration for minimal downtime

It replicates Block Volume backups to a target region, enabling smooth data migration

Migrate Virtual Machines from an on-premises environment to containers in Oracle Container Engine for Kubernetes (OKE)

Migrate Virtual Machines from an on-premises environment to Oracle Cloud VMware Solution (OCVS)

Migrate Compute instances between different OCI Regions

Migrate Virtual Machines from an on-premises environment to OCI Compute instances

At both the Primary and Standby DR Protection Groups

DR Plans are automatically generated and cannot be created manually

Only at the Standby DR Protection Group

Only at the Primary DR Protection Group

To access the cluster using kubectl, you have to set up a Kubernetes manifest file stored in the $HOME/.manifest directory

When a cluster's Kubernetes API endpoint has a public IP address, you can access the cluster in Cloud Shell by setting up a kubeconfig file

The only available option when a cluster's Kubernetes API endpoint has a public IP address is to control the cluster locally using kubectl and the Kubernetes Dashboard

To access the cluster using kubectl, you have to set up a Kubernetes configuration file stored in the $HOME/.kube directory

Both HCX Manager and HCX Connector are deployed in the OCVS environment to facilitate bidirectional migrations between cloud instances

The HCX Manager is installed in the source environment to initiate migrations, whereas the HCX Connector receives the migration traffic in the target OCVS environment

The HCX Manager is deployed in the OCVS environment as the Tunnel receivers, whereas the HCX Connector is installed in the on-premises environment as the Tunnel initiators

The HCX Connector is responsible for WAN optimization and network extension in the OCVS environment, whereas the HCX Manager handles these tasks in the on-premises environment

Virtualization offers more flexibility in terms of application dependencies

Virtualization maximizes efficiency by running multiple applications on the same OS kernel

Containers require a full operating system to run, whereas virtual machines share a single operating system

Containerization allows for more efficient utilization of hardware resources by sharing the host operating system

Thick provisioning

Encapsulation

Oversubscription

Overprovisioning

Expose running workloads internally and externally

Conduct comprehensive testing and monitor performance metrics

Gradually shift traffic from the source environment to OKE

Efficiently manage packages with Helm charts

Each subnet within a VCN employs multiple route rules, allowing for diverse routing paths based on traffic priorities

A subnet in a VCN is associated with a single route table, dictating how outbound traffic from all Virtual Network Interface Cards (VNICs) within that subnet is directed

If no route rule matches the network traffic you intend to route outside the VCN, the traffic is sent to the Internet

VCN local routing necessitates manual configuration of route rules to facilitate infrastructure communication

HCX Bulk Migration

Oracle Cloud Migrations service

HCX vMotion

Block Volume Replication

HCX OS Assisted Replication

OCI Block Storage inherently provides better IOPS performance than vSAN for all workload types

OCI Block Storage can be scaled up or down independently of compute resources, unlike vSAN which scales with the cluster

vSAN requires an external network connectivity to synchronize data across hosts, whereas OCI Block Storage does not

vSAN is tightly integrated with VMware's SDDC ecosystem, thus allowing for storage policies to be directly applied to VMs, whereas OCI Block Storage operates as independent block volumes

OCI Block Storage can utilize VMware-specific storage policies for VM provisioning and management, just like vSAN in the OCVS environment
