Getting to Know the Concept of Disaster Recovery, and Innovative Solutions: Regional Disaster Recovery for Red Hat OpenShift

CIOs, IT directors, and system administrators understand that disasters can occur and result in serious disruptions in business operations. Whether it is a natural disaster or a fatal system failure, neither can be predicted with certainty. 

In the face of potentially large losses due to disasters, efficient recovery measures are essential. Therefore, Disaster Recovery (DR) through Regional Disaster Recovery solutions emerged as the right innovation, helping to minimize the impact and recovery time required. 

Does your business have a Disaster Recovery Plan (DRP)? If not, now is the right time to design and implement one. This article will provide an in-depth understanding of the concepts of DR and Regional Disaster Recovery, helping businesses understand the importance of planning and implementing effective recovery measures. 

 

What is Disaster Recovery and Disaster Recovery Plan?

It cannot be denied that Disaster Recovery (DR) and Disaster Recovery Plan (DRP) play a crucial role in maintaining the continuity of business operations amidst the threat of disasters and serious disruptions to IT systems. 

DR is a strategy specifically designed to restore business operations following an event that could damage technology infrastructure and data. These events can take the form of natural disasters such as fires, floods or earthquakes, or increasingly complex cyber threats. 

A DRP, on the other hand, is a written instrument that details the steps and procedures an organization must take to restore its business operations following a disaster. The main goal of DRP is to minimize the disruption's impact and ensure that the organization can return to operations immediately. DRP provides operational guidance and a basis for conducting sustainability exercises and trials so that organizations are ready to face emergency situations. 

Why Do Companies Need Disaster Recovery?

No matter how strong your IT infrastructure is or how robust your cybersecurity is, at some point your business will face a situation where your cybersecurity team is unable to cope with data loss caused by a disaster or unexpected disruption. 

The good news is that Disaster Recovery can give you the means to recover from a disaster quickly, reliably, and cost effectively. With an effective solution, you can minimize data loss, speed recovery, and maintain the continuity of your business operations. 

So, what are the reasons your company needs Disaster Recovery? Here's the review: 

1. Prevent Data Loss

An effective DR solution will provide a regular, quickly recoverable backup method, ensuring that critical data is not lost during or after a disaster. 

2. Maintaining Customer Satisfaction 

It helps maintain customer satisfaction and builds trust, as customers can be confident that the business can continue to provide service even after experiencing an emergency event. 

3. Protecting Business

By having an effective DR, companies can minimize financial losses that may arise due to long downtime. 

4 Types of Disaster Recovery Plans

The following are several types of Disaster Recovery Plans (DRP) that cover various aspects of recovery after a disaster or disturbance: 

1. Virtualized Disaster Recovery Plan

Virtualized DRP aims to restore business operations with a focus on virtual environments, ensuring fast and efficient recovery of virtual machines and applications. 

2. Network Disaster Recovery Plan

Network DRP focuses on restoring network infrastructure, ensuring service availability and network reliability that are essential for business operations. 

3. Cloud Disaster Recovery Plan

Cloud DRP leverages cloud services for data storage and recovery, providing data flexibility and accessibility from anywhere. 

4. Data Center Disaster Recovery Plan

Data Center DRP focuses on the physical recovery of the data center, ensuring that critical hardware and data can be recovered to maintain the continuity of business operations.

How Does Disaster Recovery Work?

Here's how Disaster Recovery works when an unexpected disruption or disaster occurs in your business: 

1. Data Duplication

Can perform regular data backups. This data backup will usually be copied or synced to a secure external backup location or cloud storage. 

2. Secondary Site

This secondary site can be an alternative data center or cloud infrastructure that can be used to run business systems and applications. When a disaster or system failure occurs, operations are activated in a previously prepared backup location. 

3. Rebuilding Primary Site 

Recovery begins by repairing or rebuilding damaged systems and infrastructure at the primary site. 

4. Operational Change from Secondary to Primary Site

Once the restoration is complete and the main location can be used again, business operations are moved back to the main location. 

How to Make a Disaster Recovery Plan?

 

Creating a Disaster Recovery Plan (DRP) is a critical step in ensuring that critical company data can recover from a disaster or system failure quickly and efficiently. Following are the detailed steps to create a DRP: 

1. Risk Identification 

Identify any types of risks that may affect your business. This could include natural disasters, hardware or software failures, human accidents, or cybersecurity threats. 

2. Impact Analysis

Evaluate the potential impact of each identified risk on business operations, systems, and data. Determine how critical each component is to your business operations. 

3. Determination of RTO and RPO

Recovery Time Objective (RTO): Determine the maximum acceptable time to recover any system or service after a disaster event.  

Recovery Point Objective (RPO): Determine how long data can be “lost” after a disaster event before serious impacts occur. 

4. Data Recovery

Plan how you will back up your data regularly and where you will store those backups. Make sure to secure data and ensure that the data recovery process can be carried out quickly. 

5. Infrastructure Recovery

Plan recovery procedures for hardware and software. This may include ensuring the availability of backup hardware, software configuration, and installation procedures. 

6. Involving Employees

Include steps to involve employees in recovery after a disaster. Make sure that everyone understands their role and knows what to do if a disaster occurs.  

7. Trial and Revision

Conduct regular trials of DRP to ensure its effectiveness. By conducting regular tests, you can identify and correct potential weaknesses in the plan. Always update the DRP regularly according to changes in the organization or technology. 

So, to ensure you can run DR and DRP solutions effectively and efficiently, you can use the Regional Disaster Recovery (Regional-DR) solution from Red Hat OpenShift.

Introducing Regional Disaster Recovery from Red Hat OpenShift

Regional Disaster Recovery (DR) from Red Hat OpenShift is a solution designed to protect applications from major failures and disaster scenarios that can damage a data center. This solution provides maximum flexibility and no limitations, becoming an integral part of the Red Hat OpenShift ecosystem. 

This Regional-DR solution is based on the concept of dual independent clusters located in two geographically separated data centers. This way, if a failure occurs in one cluster or data center, it will not have an impact on other clusters or data centers. 

In addition, this solution can also be used on various platforms supported by Red Hat OpenShift, including on-premises and public cloud environments. 

In terms of DR management, Red Hat provides data policies through the Red Hat Advanced Cluster Management (RHACM) graphics interface. Users can use these data policies to define schedule intervals for how often application data is replicated between primary and secondary clusters, to control data loss rates (Recovery Point Objective – RPO). 

Additionally, this solution leverages Red Hat OpenShift Data Foundation (RHODF) to store metadata required for volume failover and application recovery during a disaster. With Regional Disaster Recovery, Red Hat OpenShift provides a robust, effective and flexible solution for maintaining operational continuity of business applications amidst the threat of disaster and major failure. 

3 Regional Disaster Recovery Benefits of Red Hat OpenShift for Business

Data Policy Based DR Orchestration

Data policy-based DR orchestration uses data policies to set application data replication schedules between clusters, ensuring RPO control meets business needs. 

Carrier Based DR Automation

Operator-based DR automation leverages OpenShift operators to automate the DR process, including configuration and management of data replication between clusters. 

Automatic DR Failover and Failback

Automatic DR failover and failback refers to the system's ability to automatically switch between clusters in the event of a disaster and return to its original state after recovery, ensuring RTO is achieved without significant manual intervention.
