Application Management with Cloud DRaaS

Cloud-powered Disaster Recovery service helps organizations in running mission critical applications in the event of disasters. Effective data management without losing access to key data is what the primary data centers are destined for. Maintaining business continuity whenever a disaster occurs is one of the immediate challenges that need to be addressed effectively. Meanwhile, the responsibility of running critical processes with the performance of IT systems maintained intact can be focused flexibly with cloud DRaaS availability.

Disaster Recovery (DR) was traditionally an effective means of data protection only when a disaster threatens complete disruption of organizational services. More specifically, the situation was rampant among mainframes that were based on monolithic infrastructure. DR management evolved of various phases of which the crucial one was shared DR services offered by the dedicated data recovery specialists. Though they catered to the requirements of organizations, their implementation in modern business environments almost seemed to be impractical because of them being more expensive.  This has resulted in disaster recovery on cloud at later stages.

“Secure, global information management with regional data centres is a cornerstone of our cloud strategy, and with the OpenText Cloud European Data Zone we are able to realise that strategy and further support our customers’ evolving needs,” said Gary Weiss, Cloud VP at OpenText.

Primary data centers emerged as the need of the hour to tackle disasters no matter when and how. BC/DR plans were evolved consequently resulting in the establishment of a perfect strategy enabling organizations, especially SMEs, to strengthen their data management practices. Meanwhile, the Internet formed to be the epicenter of DR implementation with the formation of public clouds and conceptualization of virtual data storage. As a result, on-demand data recovery capabilities have been improved and adapted for emerging businesses to a larger extent.

Cloud-based DR services opened up several channels enabling organizations to carve out their own customized cloud disaster recovery plans. To a larger extent, they were perfectly coordinated as per the varying data storage and maintenance requirements. Such services have been necessitated to take care of data during unexpected situations. Relying upon a secondary storage location with data migration services obtained as part of DR management will help in experiencing exceptional quality standards with ease. With the implementation of disaster recovery plans powered through cloud, a continuous business flow has been realized resulting in business continuity.

Strengthening Businesses with Cloud DR

Ever since, the concept of virtualization has struck with modern businesses with great impact, distributed applications forayed into the field offering a wide range of services such as remote management and virtual implementation. In fact, all those businesses relying upon IT services get to obtain valuable benefits such as the ones mentioned below.

Operational continuity of key business processes with location independency

  • Businesses get to enhance their performance capabilities by taking care of multiple operations at the same time resulting in business continuity

Tactical management of business processes in case of disruption to secondary services

  • Disaster recovery based upon cloud will help in executing immediate tasks without affecting the backup services as per the need.

Network maintenance without any overloads with the successful failover of workloads

  • Executing tasks with the realization of component maintenance across various networks will ensure evading of disasters effectively.

Additional strengths of cloud DR such as migrating enormous levels of data during unexpected situations will compound the growth prospects of IT services under challenging environments. On-demand cloud based disaster recovery services could be implemented without influencing the performance of primary data centers.

Managing multiple applications by striking a perfect balance between the key metrics within the organization such as RTO (Recovery Time Objectives) and RPO (Recovery Point Objectives) will help in meeting the core objectives of businesses in an exceptional manner. It is out of context to mention that any organization’s DR requirements will be conceptualized and scaled based on RTO and RPO.

Cloud DR Models – An Introduction with Key Insights

There are three distinctive DR models evolved after determining the prospective requirements of organizations in case of a disaster.

Data Model

Data backup is one of the crucial functions carried out through strategic DR management framework within any organization. This DR model reflects fundamental recovery process during which the first and foremost importance will be given to a single entity known as data. Principally, the actual task involves data protection irrespective of the location including file servers, home directories, and so on. By citing specific DR location in the cloud, the corresponding organizations will be able to access them later in the event of any disasters.

Application Model

Replicating the entire application data into the cloud sensing any disaster is a much more complex process. Secondary deployment of the corresponding application has been made available on a permanent basis with all the data secured at a virtual location. During the entire process of migrating data, the native application plays a key role with the DNS changes handled accordingly. The creation of another instance of application elsewhere will help in data management in the cloud on a consistent basis.

VM Image Model

Of all the DR models in existence, the most comprehensive one is VM image backup. The actual process involves the migration of entire virtual machine image along with the data available. During the process at any level, the necessary access is provided through DNS changes reflecting the fact that VM image has been reduced to a secondary entity. It is because of this flexibility due to which real-time application deployments too are completely monitored and fully protected.
