In a recent entry I gave some examples of how cloud storage is maturing. There are companies offering cloud based storage solutions both as a service, like Amazon and Nirvanix, and as a product to sell to service providers or for internal use, like Bycast and ParaScale. Some of these companies even have revenue customers and they are organizations of all sizes, as we stated in our recent white paper, Cloud Storage Is A Reality. What is missing, however, is how to get data to these cloud storage platforms.Part of the challenge of getting data to the cloud is how cloud storage solution providers deliver access. Most support a variety of access methods, including common Internet Protocols WebDAV and HTTP, and now many are adding direct support for NFS and CIFS. With these more common protocols the cloud becomes a mount point on your network, but does incur some potential performance bottlenecks prone to these protocols, CIFS in particular. The performance issues have to be balanced against ease of use.

Interestingly, as part of that access, some suppliers are even implementing a local NAS cache that gives the users local speed and access while it trickles the data to and from the cloud. This also can resolve some of the performance issues related to CIFS and NFS by converting to a more Internet-friendly protocol at the appliance. With this type of technology in place, there's no reason that you could not use a real-time compression appliance such as Storwize's to actually compress that data prior to it being stored in the cloud. This effectively cuts your monthly cloud storage bill in half or more, as well as optimizing your connection speed.

There also are a host of companies, especially in the public cloud space, that are offering software which will synchronize data to the cloud like Dropbox and others. This allows you to again have that local access and yet have it stored in the cloud, which is ideal for individuals with multiple machines and companies wanting to collaborate and share data.

There also are companies doing more than just storing data. For example, Soonr will synchronize your data and convert that data on the fly to a format that the device you're accessing it with can read. If you want to view your presentation on your iPhone, for example, it will convert the slides to a series of .JPEGs.

Lastly, we will see archive software and backup software vendors begin to have an option to have cloud storage be a form of archive or backup target with native support of the above protocols or by using the cloud supplier's API set. This could even lead to "cloud RAID" or multicloud copy, an idea I heard about from a stealth startup company called Lookwithus that provides rich media collaboration tools to the cloud.

Cloud RAID or multicloud copy could be an ideal solution for those who are sold on the cloud storage concept but not a particular cloud storage supplier. This would allow you to move data into two cloud providers at the same time. Assuming the software can track the existence of both copies, management would be seamless and concerns about access or viability of a particular provider would be greatly minimized.

CVE-2018-12716
PUBLISHED: 2018-06-25
The API service on Google Home and Chromecast devices before mid-July 2018 does not prevent DNS rebinding attacks from reading the scan_results JSON data, which allows remote attackers to determine the physical location of most web browsers by leveraging the presence of one of these devices on its l...

CVE-2018-12714
PUBLISHED: 2018-06-24
An issue was discovered in the Linux kernel through 4.17.2. The filter parsing in kernel/trace/trace_events_filter.c could be called with no filter, which is an N=0 case when it expected at least one line to have been read, thus making the N-1 index invalid. This allows attackers to cause a denial o...

PUBLISHED: 2018-06-24
GIMP through 2.10.2 makes g_get_tmp_dir calls to establish temporary filenames, which may result in a filename that already exists, as demonstrated by the gimp_write_and_read_file function in app/tests/test-xcf.c. This might be leveraged by attackers to overwrite files or read file content that was ...
