IBM was one of the first companies to begin manufacturing punched cards. For almost four decades, punched cards were the major medium for storing, sorting and reporting data processed first through punched card equipment and—later—computers. Colloquially known as “IBM cards,” the punched cards were so embedded in business operations that by the 1950s, they represented over 20% of IBM’s revenue. On this day in 1971, IBM announced a new version of the IBM 3525 Card Punch replacing incandescent lamps with LEDs—a new technology at the time—to read punched cards. While the punched card may now be a thing of the past, LEDs are as relevant as ever, with new applications being actively developed. In retrospect, with a bit of serendipity, one great innovation passed the baton to another.
Cloud storages today are a terrific alternative to saving data on local computer system or in NAS storage. Begun with Amazon S3, such options are used by a lots of business, consisting of Microsoft with their Azure Blob Storage.
The benefits of cloud storage are nearly infinite storage capability (usage as much as you need, not as you have), the range in between the storage and your location (the data won’t be lost in a mishap or fire, and access of third parties to your information is severely restricted), reduced expense of data management.
At the same time cloud storage works in the way that does not match regular approaches to storage gain access to, such as hierarchical file systems and relational databases. Internally designed as substantial tables with an index and BLOB field for information, they do not give enough versatility that submit systems or database management systems can offer to the developer and user. The developer needs to carry out translation in between the data he has in the application and the back-end cloud storage.
Another substantial drawback is a distinction between APIs, used by different services. While the majority of services provide so-called REST API, this API remains in truth a format for requests and responses sent over HTTP. Demand commands, criteria and functions provided by services, differ significantly. Due to this switching in between cloud services needs writing of different code for each API.
Lastly, the primary factor of (in) acceptance of storage based services is a concern of ensuring information safety. Though company inform us about file encryption used on their side, such encryption is performed on their systems and there’s no guarantee that it’s really reputable and if it is even carried out. So security of the data is a real problem and not a dream of cloud storage challengers.
Luckily, there exists a possibility to address all of the above problems in a simple and really cost-efficient way.
Solid File System (SolFS) provides the missing pieces that fit well into cloud storage architecture.
As many file systems, SolFS is page-based. This indicates that it operates not with random series of bytes, but with blocks (sectors on the disk, pages in memory) of repaired size. This makes it simple to back SolFS with practically any storage.
To make such backing possible SolFS supports callback mode, in which it asks your application to shop or obtain the block to or from the back-end storage. So all you need to do is implement two basic functions “put the page #X to the cloud storage” and “retrieve the page #X from the storage” in your code, which’s all - you have a file system in the cloud!
However that’s not all SolFS can use. The file system offers several advanced functions, such as built-in file encryption and compression (performed on your side, if you keep in mind the cloud security issue referenced above), nearly unlimited possibilities for saving metadata (various supplemental information about the main file or data), and to carry out SQL-like search for files. Moreover, if you need custom encryption (eg. using secrets kept on cryptographic hardware tokens), this is possible with two other callbacks - “encrypt page #X” and “decrypt page #X”.
And what if you need not a file system, but a relational database? No problems either! You can utilize your favorite DBMS and have it save it’s files on the virtual disk, developed by SolFS (System Edition). In this manner the database files are saved in the cloud storage, and your application deals with them through database management system of your option.
Another advantage of SolFS is that moving from one cloud storage service to another is as simple as rewriting 2 standard functions for storing and recovering of pages to and from the cloud storage.
You can say that you still need the code, that works with the cloud. This is appropriate, but it’s a lot easier to compose the code that shops and obtains fixed-sized files (each page has the very same size) by page number, than to try to carry out a relational database or a file system in the cloud yourself.
If you don’t want to compose cloud-specific code at all, we have a solution for you too. It’s CloudBlackbox - the elements that offer uniform access to different cloud storage services. These parts both supply consistent access to cloud storages (Amazon S3, Microsoft Azure at the moment with more to come) and supply improved encryption abilities, such as certificate-based file encryption of information. So if you are moving to the cloud, you do not require to discard recognized paradigms and existing code. Updating them to modern industry offerings is simple and fast.

10XDRIVE REVIEW-Got Cloud-Computing?
Do I need a CDN if I have Cloud Computing?
Over last year or so, the term Cloud Computing has actually been making headlines. There are numerous new entrants into the Cloud Computing industry. The concept is basic, you have all these computers or servers straight linked to the cloud (The Web) and you have huge computing power within your reaches. Companies like Rackspace, GoGrid, Amazon, and AT&T are all providing one kind of Cloud Computing or another. The services offered from these business range from basic “Cloud Storage”, to totally scalable virtual servers in the cloud. When to utilize Cloud Computing The excellent feature of these services is the instant setup and “unlimited scalability”. When you want a brand-new site, with a few clicks of a mouse you bring up a new Linux or Windows box. They even make it simple for you by pre-installing services like SQL, Mail, and in some cases applications like Wowza or Windows Media streaming server. The setup process is usually wizard driven and they take the uncertainty out of setting up server software and services. A number of cloud-computing companies even partner with Content Shipment Networks (CDN) to provide Cloud Storage. Essentially you put your files in the cloud storage and they are on a CDN. Sounds good, why do I even think about a CDN?
All of these services are on virtualized boxes and shared resources. They are not dedicated. The services are not fully handled either. You would be responsible for software updates, spots, licenses, etc; although you actually should not ever be worried about hardware or bandwidth. The concept behind cloud-computing is that you simply pay more and they devote more resources to your servers. If you have an existing information center or web servers, you may be reluctant moving your web sites or web servers to a cloud-computing Company. This might suggest deserting software and hardware you’ve currently purchased. You may think about bringing up brand-new servers in a cloud environment to lower costs or get flexibility. If you have a lot of web sites it might make good sense to consider a cloud supplier versus a regular web host service provider. You will have more control over your domains and depending upon your service provider you might be able to scale simpler. Plus you would have full root access to the web servers to configure them however you desire. It would be like a devoted server bundle from a webhosting company. If you plan to utilize a cloud calculating company in lieu of a CDN, thinking you can just construct your own CDN within their cloud, reconsider! Start asking your cloud-computing supplier these concerns: how many data centers are they in? What type of peering arrangements do they have? What are their peek bandwidth capabilities/egress abilities? Where in the world are they hosted? Will your servers be replicated everywhere all over the world or just in the US, just in one information center? Exist more expenses involved for Europe, Asia, or Australia shipment? What if you need streaming servers for videos, can they do that? What about mobile delivery? Do they provide token-based authentication? Pseudo Flash Streaming? What about encoding and transcoding? Does your cloud-computing vendor have any content management software or video? Do they support live video delivery? These are all questions to consider if you believe you wish to use a cloud-computing business rather of a CDN. A tier 1 CDN like Limelight or Akamai will have thousands of servers to cache your content around the globe. They will provide all those supplementary services related to content shipment. A CDN will support streaming and HTTP progressive downloads. They will most likely have Adobe, Microsoft and Apple servers. A CDN will be able to support live occasions. On top of that you will have the ability to accelerate your entire website, with Akamai’s DSA or Spotlight’s Spotlight Site services. You are not restricted to just videos with a CDN, any piece of content can be delivered through a CDN. You will probably discover that integrating a CDN is easier and less time consuming than raising brand-new servers and maintaining them. In many cases with a CDN it may be as simple as pointing a CNAME to the CDN or simply submitting your material to them. Pricing Certainly, the pricing of cloud-computing is more appealing than a CDN. However you will require to determine what your needs are and discover the ideal mixes of services. Mosso by Rackspace $ 100/month. 50 GB of storage space. 500 GB of month-to-month bandwidth. 10,000 compute cycles. Compute cycles determine how much processing time your applications require on the Mosso cloud. 10,000 calculate cycles are approximately equivalent to the monthly capability of a server with a 2.8 GHz modern-day processor. each month. Costs increase from there. GoGrid:. $.19/ hour of RAM (add more RAM, pay more) $136/month per 1GB of RAM plus. $.50/ GB of transfer outbound. 10GB of storage included $.15/ GB afterwards. Free Load Stabilizing with F5 load balancers. Amazon EC2:. $.10/ hour approximately $.80/ hour for “As needed”. $ 325 setup up to $2600 setup + $.03/ hour as much as $.24/ hour for a “Reserved” server. $.10/ GB on inbound traffic. $.10 to $.17/ GB for outbound traffic. Storage is extra through the S3 service. Other services are additional. AT&T Synaptic Storage as a Service:. Prices not disclosed. CDN Rates. Prices for CDN service will vary greatly depending on what you want and where you get if from. With the Tier 1 CDNs anticipate a minimum commitment each month and to sign a 1-year contract. With a Tier 2 CDN like Level3, CDNetwork, Edgecast, etc, you might get a month-to-month agreement and lower prices, however you may not get the same service either. Prices for CDNs will be anywhere from $.05/ GB to $1.00 or more per GB depending on what you commit to. Remember only the largest agreements in the numerous TBs to Petabytes will get down to the $.05/ GB range. When you include on ancillary services, you will contribute to your monthly expense too. It appears that Rackspace wins on pricing, although as you include on more CPU Cycles and storage they may increase significantly. Rackspace is also known for their client service, which will count for a lot. Amazon’s pricing appears complicated and complicated, it looks cheap on the outdoors, but if you add up all your inbound/outbound, storage and class of service, their prices isn’t too aggressive. Also, Amazon is not understood for customer service at all. Getting a hold of tech support might be a task. GoGrid’s prices is very near to Rackspaces’ and their item appears excellent, also the complimentary load balancing counts for a lot, so don’t count out GoGrid. Lastly, AT&T has only just revealed their cloud storage product. Their website doesn’t divulge pricing. Best of luck getting somebody at AT&T on the phone that can help you understand their item. Conclusion. If you’re taking a look at Cloud Computing to increase site performance, you might consider a CDN first. Take a look at why your website is under carrying out. Do you require more databases, do you need more mail servers? Do you require more domains? These are all factors to get cloud computing. However if you have a lot of videos, music or software downloads or your pages are sluggish, then a CDN is the way to go! Preferably, your best service will be to utilize both a cloud-computing business and a CDN. This will offer you optimal performance, flexibility, and dependability.
