What is Business Continuity Solutions ?

Simply put, a Business Continuity (aka, BC) solution is based on a plan 🙂
A BC plan is a predefined approach and procedure for how a business will continue to run when dealing with an emergency.

In another words, it is a process of creating systems of prevention and recovery to deal with any potential threats to your company.  These threats could be a natural disasters, such as hurricanes, fires, floods, power outages or an unintended misconfiguration of a system. It could also be a malicious cyberattack as well.

There are many benefits provided by BC planning and Disaster Recovering (aka, DR) planning to your organization when they are drafted and approved across the board, such as:

  • Improved decision-making
  • Risk Management
  • People and Property Protection
  • Morale boost 🙂

The “Morale boost” element is very important piece, because when employees know plans are in place, they may feel safer. Moreover, it does not just boost morale, but potentially increases the business value perception to customers who recognize the high preparedness and responsibilities of the company.

What are the Backups and Disaster Recovery solutions in Azure?

In the case of service disruption or accidental deletion or corruption of data, recover your business services in a timely and orchestrated manner. The Azure backup and disaster recovery solution is simple to architect, cloud-native, highly available, and resilient.

Azure Backup and Disaster Recovery (DR) services are important services that help you to achieve your company’s reliability goals for all of the system workloads in the cloud or on-premises. It is very important when CSP (Cloud Solution Provider) prioritizes transparency and keep it’s customers informed during and after the service issues.

You could easily target following goals when planning to deliver your Backup and DR services to your most critical customers:

  • Simplified Management across environments
  • Azure built-in security controls
  • Reduced complexity and cost
  • Extent solutions to Azure with our partners
