Managing Risks with Business Continuity Planning

Every business enterprise is created with the sole aim of gaining profits from the business. However, this legal entity is a risky affair and is prone to disruptions. Business disruptions can come in from various sources including natural ones. In the technology driven world today with radical environmental changes, the risk to the continuity of business is even more. The unplanned events may leave lasting impressions on both small and medium enterprises as well as global organizations. The brave heart entrepreneur and business enterprise thus needs to be always prepared to face the disruptions and keeps options ready to ensure business continuity come what may.

Today, as part of   smart business operations, enterprises opt to have in place strategies for business continuity as part of operations management.  The business continuity planning (BCP) is meant to identify an organization's exposure to internal and external threats and prepare the assets to provide effective prevention and recovery mechanism for the organization, while maintaining a competitive advantage. Wikipedia defines the business continuity plan as a road map for continuing operations under adverse conditions irrespective of this being natural or man-made.

For enterprise that are totally technology dependent any small system errors and bug in the complex programs can bring their entire business to a standstill.  Thus the business continuity strategy works to provide a framework for resilience building and tends to protect the interest of key stakeholders. Traditionally what the business continuity plans looked at is methods to protect the business in face of physical damages to equipment, products and disruption of services. However, with the globalized business world so driven by technology, even the absence of the key staff can cause equivalent effects on the business.

Today the business continuity planning strategies should be one that would help global enterprises face emergency situations without loss of productivity and profit. The technological innovations have paved way for new age enterprises to provide remote desktop  access to their distantly located employees and key personnel. Such remote access solution is best if it can facilitate enterprises with:
 
  • Anytime, anywhere access for employees to familiar workstation  and business critical resources
  • Real-time and secure access gateways to the corporate network and critical data  for the partners and vendors
  • Performance consistency for the entire workforce
  • Automated VPN provisioning
  • Cost-effectiveness and global redundancy

Enterprises make use of remote access and BYOD solutions to increases the mobility of the workforce and ensure business continuity. But along with the increased mobility they also need to cater for cost-efficient performance of the corporate network infrastructure. Load balancers play a major role in disseminating process requests of the workforce across the wide networks irrespective of the device and location.  The modern day innovative load balancers help enterprises to leverage on the multi-core processing and ensure a scalable business continuity planning through cost-efficient performance.

Business Continuity Planning -Safety In face of Adversities

Every business irrespective of being a small and medium one or a large conglomerate is a profit oriented one. Technological innovations deployed in the business environment aids in globalized expansion of the business and leads to revenue generation and increased profits. However, any disruptions either minor or major may have serious impact on the day-to-day business operations.

Foreseeing business disruptions or the time when disaster strikes in an unknown factor and the globally bound organizations today are faced by the challenge of maintaining business continuity in face of all storm. Business continuity planning is one of the main strategies taken up by the global organization. Spread across geographical boundaries and remotely distant locations, these organizations need to be ready to face any disruptions in the business operations while ensuring that work goes on without any serious impact.

Business disruptions may result from various reasons such as epidemics, transit strikes, cyber-attacks, natural calamities etc. Under such circumstances a detailed remote access strategy and business continuity planning (BCP) will help the global enterprises to deal with emergency situations and help them to avoid loss of productivity or revenue. The remote access solution must be one that would help enterprises with:

* Secure anytime, anywhere access leading to uninterrupted business continuity
* Maximum performance, automated VPN provisioning
* Cost-effectiveness and global redundancy

A continuous delivery of critical services and products, demands that organizations need to have the facility that permits them to recover data, application and assets in a real-time access mode. As Gartner's analyst suggests that the most critical success factor to any business continuity plan is fast re-establishment of business processes. However, if the disaster recovery plans do not include Remote Desktop Access, no amount of technology can save business operations. Hence the real-time access to information will facilitate the employees to continue work from any location, allow business partners and suppliers an uninterrupted access to important information. Such actions will minimize the disruption levels of business processes and applications.

With large number of vendors offering business continuity planning solutions, enterprises need to make the most of the benefits to ensure productivity at all times. The enterprises needs to decide on appropriate ones and service types required for the business environment. The availability of applications from the corporate network and remote desktop access will help mitigate business disruptions. Application availability solutions from leading service provider’s offer load balancers and WAN optimization controllers for any fail-over for WAN links, devices and data centers.

However, the enterprises need to ensure that anytime anywhere remote access to business critical information also poses issues of data and network security. Thus service providers of business continuity planning solutions also need to ensure that the corporate network are equipped with secure access gateways that can support multiple access.
