Through File Systems to this Fog up and Back


Cloud storages at this time are a wonderful alternative to storing records on local computer or in NAS storage. Started off with Amazon S3, many of these solutions are offered by several of companies, like Microsoft company with their Orange Blob Safe-keeping.

The benefits of cloud safe-keeping happen to be nearly infinite storage space total capacity (use as much as you need, certainly not while you have), the range between your hard drive and your current location (the data refuses to be lost within an crash or maybe fire, plus admittance of third parties in your data is severely limited), lowered cost of info managing.

At the very same time cloud storage functions in the way that will doesn’t match regular solutions to storage access, like hierarchical file programs together with relational databases. Internally designed as huge tables using an index and BLOB arena for records, they have a tendency supply enough flexibility the fact that record systems or data bank management systems can offer you to the developer and even user. The developer has to accomplish translation between often the data he has within the application plus the back-end cloud storage.

An additional considerable disadvantage is the big difference between APIs, presented by way of different services. When many of services offer so called REST API, this API is in truth the format for requests together with responses sent over HTTP. Submission commands, parameters together with capabilities offered by means of providers, vary significantly. Due to be able to this switching involving fog up services requires creating of separate code per API.

Finally, the main aspect of (in)acceptance of safe-keeping based treatments is some sort of question connected with guaranteeing info safety. Although service vendors tell us about security used on their aspect, such security is carried out on their programs and there’s no guarantee the fact that is actually seriously reliable and if the idea is perhaps performed. And so safety involving the records is a real issue and not a illusion of cloud storage oppositions.

Luckily, there exists some sort of opportunity to address all of of the above complications in a simple plus very budget-friendly way.

Solid File System (SolFS) presents the missing pieces of which fit well into cloud storage architecture.

As just about all data file systems, SolFS is page-based. This means that it operates avoid accidental sequences of bytes, but with blocks (sectors within the disk, pages in memory) of fixed size. This makes this easy to rear SolFS with almost any kind of hard drive.

To generate such support possible SolFS supports callback mode, where this asks your application to store or maybe retrieve the wedge in order to or from the back-end storage. So all an individual need to do will be employ two simple characteristics “put the page #X into the cloud storage” plus “retrieve the page #X from your storage” in your own personal code, which is all : you have a data file system in the cloud!

Nevertheless that’s not necessarily just about all SolFS can offer. Often the file system provides various advanced features, such as built/in encryption and data compresion (performed on your side, in case you remember the cloud security trouble referenced above), nearly endless possibilities intended for storing metadata (various supplementary information about the key file as well as data), and to accomplish SQL-like search intended for data files. Moreover, if (eg. using keys saved on cryptographic hardware tokens), this specific is possible with a pair of other callbacks – “encrypt page #X” and “decrypt page #X”.

And exactly what if you want not a new document system, but a relational database? Virtually no problems either! You can use your preferred DBMS and have it keep it’s files on the exclusive disk, designed by SolFS (System Edition). This way the database files are stored in the particular cloud storage, and your app works having them via database software management program of your choice.

1 more advantage of SolFS is that moving in one cloud storage service to one other is as simple as rewriting two basic capabilities intended for storing and retrieving of pages to together with from the fog up storage space.

You can say the fact that you still need the computer code, that works using the fog up. This is correct, but it’s much easier for you to produce typically the code that will stores and retrieves fixed-sized files (each page offers the same size) by means of page number, than to try out to implement a relational database or a report system inside cloud by yourself.

If you don’t need to write cloud-specific code in any way, we have a solution for you also. Is actually CloudBlackbox – the components the fact that provide uniform access for you to various cloud storage solutions. These components both supply standard access to cloud storages (Amazon S3, Microsof company Azure in the second using more to come) in addition to provide enhanced encryption functionality, such as certificate-based encryption of information. So if a person are moving towards the fog up, you don’t need in order to discard set up paradigms in addition to existing computer code. Updating them to modern field solutions is easy and quickly.
