Ever since Lifehacker turned me on to Dropbox, it's become one of the most essential pieces in my daily workflow. Sure it syncs files extremely well, but Dropbox is an excellent tool for so much more.
At Backblaze, we provide unlimited storage to our customers for only $5 per month, so we had to figure out how to store hundreds of petabytes of customer data in a reliable, scalable way—and keep our costs low. After looking at several overpriced commercial solutions, we decided to build our own custom Backblaze Storage Pods: 67 terabyte 4U servers for $7,867. In this post, we’ll share how to make one of these storage pods, and you’re welcome to use this design. Our hope is that by sharing, others can benefit and, ultimately, refine this concept and send improvements back to us. Evolving and lowering costs is critical to our continuing success at Backblaze. Below is a video that shows a 3-D model of the Backblaze Storage Pod. Continue reading to learn the exact details of the design
In my last project at work, I had to replace NFS with GFS2 and Clustering. So in this tutorial I will show you how to create a Red Hat or CentOS cluster with GFS2. I will also show you how to optimize GFS2 performance in the next HowTo, because you will quickly notice some loss of performance until you do a little optimization first.I will 1st show you how do build a Cluster with GFS2 on the Command Line and in the next tutorial I will show you how to do the same thing using Conga.
SUSE Studio is a free, web-based service designed to build virtual appliances, such as pre-installed hardware-appliances, or "software appliances" -- pre-configured Linux server stacks suitable for installation by users on real or virtual commodity hardware. Recently released from beta, SUSE Studio can produce appliance images in raw disk image, Live CD/DVD iso, VMware, and Xen formats, and there are plans in the works for supporting Amazon's EC2 ami format, says the review by our sister publication, eWEEK.
Talis Connected Commons The Talis Connected Commons scheme is intended to directly support the publishing and reuse of Linked Data in the public domain by removing the costs associated with those activities. The scheme is intended to support a wide range of different forms of data publishing. For example scientific researchers seeking to share their research data
Platform-as-a-Service (PaaS)
The VMforce collaboration is VMware’s first public implementation of Platform-as-a-Service (abbreviated as “PaaS”). PaaS offerings aim to make developers incredibly efficient by hiding many of the complexities that they face in typical enterprise IT environments such as:
* Waiting for the provisioning of physical machines and their software
* Changing your code to work with the specific middleware components your company uses
* Handling code modifications that may be required as the middleware versions change
* Dealing with new environments as your code moves from development to staging to production
* Frustrating interactions with the separate operations team when things aren’t working well
PaaS offerings typically offer add-on services available for developers to incorporate into their applications. These include capabilities such as location-based services, identity management, tweeting, chatter, search, and many forms of data storage. The developer efficiency and application richness to be gained through PaaS offerings is clear and we see it as one of the major trends in cloud computing. Today’s PaaS offerings are not without challenges though, and we believe VMware is in a unique position to attack these challenges and help bring PaaS to the mainstream.
Eigenes Profil soll per "Near Field Communication" auf beliebigen Rechner übertragbar sein - Daten verbleiben auf dem Smartphone Das iPhone 4 erst vor wenigen Monaten auf den Markt gebracht, intensivieren sich bereits die Gerüchte um die Folgegeneration des Apple-Smartphones. So will man nun etwa bei Cult of Mac wissen, dass das iPhone 5 mit einem Chip für "Near Field Communication" (NFC) ausgestattet sein soll, der so manche spannende Nutzung ermöglichen könnte.
