Overview

Covid-19 has caused many, if not most, of technology professionals and organizations to work remotely to avoid any further spread. As a result, technology departments of organizations are looking to develop solutions and services to effectively manage teleworkers by using insights into location, availability, contracts, reasons, and distribution data by geography, by work status, by the department, by job code and more. Database-as-a-Service (DBaaS) describes a cloud-based, self-service model for deploying databases and database applications to end users without requiring a considerable amount of effort from IT staff, DBA, or an Application team to deploy or manage the database instances.

Benefits of Oracle Database Cloud Service

Enterprises are demanding the simplicity, flexibility, elimination of duplication, and agility of the cloud while keeping their options open on where to run the workloads. The same goes for databases; they want the cloud operational simplicity of service without restricting their platform choices.

DB as service includes diverse data management, user and role management, styles, localization, and more.

Key Benefits

  • Make changes in minutes not months
  • Save up to 80% over traditional contact center solutions
  • Easily scale to meet unpredictable demand
  • Flexibility and agility
  • “Only pay for what you use”

Database Services Available

DbaaS on VM

Basing a DBaaS reference architecture on VMware versus Realize Automation gives robust architecture for running a DBaaS solution. This accelerates the deployment and management of applications and computes services, thereby improving business agility and operational efficiency.

 

Automation on Cloud with DbaaS

DbaaS creates and runs as many tasks as possible to ensure everything is working properly for both pre-shift and post-shift. Also, making sure certain tasks continue to run regularly in order to identify the steps taken while monitoring them and quickly discovering if anything has broken previous work completed.

Elasticity

DBaaS combines cloud orchestration and automation with turnkey DBA services delivering a secure, performance-rich, multi-cloud experience with high availability and on-demand scale with high scalability.

Backup

Backing up your Database Cloud Service (DBaaS) instances can protect the instance software, configuration and database against loss if a failure occurs. When restoring an instance from a backup, you can restore the instance software, configuration, and database to its original state at the time of the backup.

Auto backups can be enabled from OCI console and the backups will be taken and stored into OCI object storage, please refer to the visual below:

Visual One

 

Self-Service Provisioning

Database Self Service Portal, users can select a service template that closely resembles their requirements which identifies the size and configuration of the database to be created.

Visual 2

Patching:

From the OCI Console, select database to be patched and click on database node name and patching can be done using on click from OCI Console. Patching is done after performing the pre-check and finally clicking on the Patching button

Migration Options and Approach

When Migrating to Oracle Cloud Infrastructure there are several distinct strategies that you can consider as high-level strategies for planning migration and requirements.

Details listed below will explain the migration option and approach you want to take.

 

Strategy

Option Description

Approach Example

Rehost

This strategy for migration is also referred to as "Lift and Shift". It involves taking a snapshot of the application server VM's on the source environment including the OS, boot record, converting into an Oracle Cloud Infrastructure - compatible format (qcow2, vmdk) and importing it onto Oracle Cloud Infrastructure as a custom Image, and then re-instantiating the image.

You have non-Oracle applications, running on a VM on Oracle Cloud Infrastructure Compute Classic. These applications cannot be easily rebuilt.

In this case, you create a snapshot of the entire image (OS, application, configuration information, and data) import it into Oracle Cloud Infrastructure and rerun it there–essentially, you are rehosting the application server from Oracle Cloud Infrastructure Compute Classic to Oracle Cloud Infrastructure.

The application can also be an on-premise database deployment, which was installed and configured on the source virtual machine.

Replatform

This strategy involves rebuilding or redeploying the application on an upgraded operating system.

You create a new Oracle Cloud Infrastructure virtual machine, based on a new version of the Oracle Linux operating system with the latest security updates. You can then redeploy your application on the new virtual machine and the new operating system.

For example, consider the task of migrating PeopleSoft using Cloud Manager. This operation reinstalls PeopleSoft on a new Oracle Cloud Infrastructure VM, and moves just the configurations and data over.

Refactor

This strategy involves redesigning and refactoring your application with cloud design points to make it more cloud-native.

You redesign and rewrite your application to make extensive use of Oracle Cloud Infrastructure constructs and Oracle Cloud Infrastructure PaaS services, so you get the maximum benefit out of moving to the new infrastructure.

This may be the only solution to migrating complex network configurations.


Retire/

Replace



These are not covered in detail here. With this strategy, you basically discard your application or buy another application. In these situations, there are no migration scenarios.

Conclusion

As you can see, the benefits of using the Cloud Manager enables time-saving and cost-saving options.

  • Provision PeopleSoft environments on Oracle Compute Cloud and Oracle Database Cloud Services.
  • Orchestrated deployment of PeopleSoft 9.2 Applications on Oracle Cloud.
  • Subscription model to auto-download application PIs and PRPs.
  • Automated migration of on-premise environment to Oracle Cloud.
  • Create repeatable deployment templates.
  • Self-service provisioning of PeopleSoft environments.
  • Fully automated deployment which is immune to manual errors and process delays.
  • Manage multiple environments from a single page.
  • Perform on-demand health checks on environments.
  • Enable application life-cycle management in Oracle Cloud.
  • Clone environments by creating templates from running instances.
