A person’s or organization’s storage needs vary from time to time. When the data being stored increases, the individual must also comply and expand the cloud storage. Public cloud storage has an advantage in this corner, since all you have to do is communicate with your hosting company and ask for more storage space albeit for a few more dollars. Other forms of cloud storage might force you to buy additional equipment when scaling up.
Since the cloud storage company is in business, we can expect that they have a vast network of servers and backups in case there is a failure or corruption of data. Whenever a data center fails, the load is taken over by the remaining centers, making it virtually impossible to fail.
Cons of public cloud storage
The most prominent concern when it comes to public cloud storage is the security of the data stored in the cloud. Since most of the companies have these data centers in various countries, enforcing a particular set of security and compliance rules becomes problematic. There have always been concerns that due to the multi-tenancy support, there are vulnerabilities that can be exploited to reach other people’s data. Since developers are also utilizing popular cloud storages in their applications, the data access protocols can be used to provoke data loss. This means essential data can be wiped out in a matter of seconds.
Another major aspect is downtime. The most extensive DDoS attack happened in 2013 with whopping speeds of 309Gbps. This is enough to deny users the access to the cloud storage until the attack is handled at which the damage could be irreversible.
