In the previous article titled, Public Clouds—Perceptions–Part I, we focused on general perceptions on why public Cloud backups and applications have succeeded.
Economies of scale have driven down costs of implementing security in public Clouds. Organizations that have adopted public Clouds have concluded that it will cost their organizations more to beef up security in their own data centers and bring it up to speed keeping pace with technology changes and increasing sophistication of cyber crimes. Organizations who have adopted the public Cloud with enthusiasm contend that top public Cloud backup services are in the business of securing their data centers and they are able to make it profitable to do so. An organization operating in a silo cannot hope to achieve the same levels in security that the public Cloud backup service can.
Customization of the public Cloud has made it attractive to enterprises that are jealous of their online look and feel. Public Clouds allow customers customize the interface and extend the appearance of their applications.
The traditional security measures such as firewalls, intrusion detection systems, virus scans and encryption systems can continue to exist within the IT systems of the organization. The add-on in the public Cloud backup is greater visibility, greater control and automated generation of alerts and audits for instantaneous action.
Other visible benefits of the public Cloud that deserve mention are:
- Real time reporting on data and application irrespective of the location of the data in the virtual world
- Impregnable and sophisticated data encryption systems that are third party certified and approved
- Redundancy of storage and high availability of data
- Ease of e-discovery
- Compliance with all the extant legislations that are in operation in different parts of the world
- Policy driven management of virtual machines
- Instant disaster recovery and assurance of business continuity
However, the road to success has not been an easy one. Public Cloud backup applications adoption has been demanding. Public Cloud backup vendor evaluation has been a time consuming line item. Diligence in evaluation of the vendor and the public Cloud product continues to be applauded as an essential ingredient to shifting data from private to public stores. The reputation of the vendor and delivery on service level agreements continues to be a basis for accepting or rejecting the services of a vendor. Data portability across Cloud vendors—that has become possible in the last few years—is often quoted as another reason for the selection of a particular vendor.
