Disaster recovery as a service (SaaS) or disaster recovery as a service is a rapidly growing category of cloud computing typically used for shielding an application or important data from a sudden or unforeseeable disaster at one geographical location. An example of a disaster recovery as a service offering is the ability to view all activity logs and search past activity for performance issues in real-time. This can be particularly useful when disaster strikes and you are unable to access your server or other applications in a data center. disaster recovery as a service is typically offered as a hosted solution with application servers that are pre-integrated with popular Web services such as Microsoft SQL, Microsoft Access, Java, and PHP. However, there are some organizations that choose to deploy their own disaster recovery applications and data.
There are a number of reasons why businesses choose to go with this form of disaster recovery over traditional disaster recovery. Perhaps the biggest reason is scalability. Disaster recovery as a Service is very scalable in nature, providing businesses with a flexible approach to disaster recovery time. Because this service is delivered on-demand, it requires little to no upfront capital investment to maintain, which presents some significant advantages. Some of these advantages include fewer complications associated with hardware, software, training, and staffing, with the exception of data backup purposes.
Another reason why some businesses prefer to use a DRaaS provider instead of a traditional disaster recovery plan is scalability. When disaster recovery as a service is deployed, there is no requirement to maintain any hardware, software, or staff to provide support at the site. Since the service is provided on-demand, disaster recovery times can be adjusted to meet the needs of an ever changing business environment.
Many people think that with disaster recovery planning, they will be investing in expensive hardware and software. This is simply not true. One of the main reasons why DRaaS is so popular is because of its ease of use. Business continuity software provides everything that is needed to restore operations after natural disasters or even a virus attack. No matter what type of disaster occurs, businesses can rest easy knowing that their data is safe and backed up.
In order to get started with DRaaS, a business must select a provider and then purchase the necessary hardware and software. The most popular types of hardware that are used in many businesses today are hard drives and tape drives. Businesses may also elect to use network attached storage (NAS) servers or file storage systems. If a business elects to use a NAS or file storage system, then they may also need to purchase server software in order to operate their DRaaS disaster recovery plans. File management software allows users to monitor the state of their entire server database.
