In this, the fourth article in our series investigating the benefits of Vembu BDR for Virtualized Environments, we examine Vembu’s backup capabilities. We all know that backing up your data is only one part of the equation. The ability to recover is the other, and arguably more important, side. This is where Vembu BDR really shines.
SDDC & Hybrid Cloud
Cloud computing has evolved from focusing only on how to construct, secure, manage, monitor, and utilize IaaS, PaaS, and SaaS clouds. As the paradigm matures, it is moving from a pure resource management paradigm to a data and resource management paradigm. (Read More)
SDDC is the next evolution in on-site data center technology. It has taken the knowledge gained from the server virtualization revolution and blended it with software-defined storage and networking to create a data center defined and managed by software running on invisible hardware.
Hybrid Cloud covers the technologies and operational processes, both technical and business, for deploying, consuming, and utilizing this paradigm.
Major areas of focus include barriers to adoption; progress on the part of vendors in removing those barriers; where the lines of responsibility are drawn between the cloud vendor and the customer for IaaS, PaaS, SaaS, and hybrid clouds; and management tools that are essential to deploying and managing the cloud, ensuring its security and the performance of applications.
Oracle is acquiring NetSuite in a $9.3B all-cash purchase. After its very shaky start in cloud computing—Ellison famously stated that the computer industry and its approach to cloud computing are highly fashion driven—the purchase of NetSuite makes a statement. Oracle is now front and center where cloud is concerned, though it is true that it is playing catch-up with the likes of AWS, Google, and Azure, and possibly, with regard to this acquisition, Salesforce. However, unlike VMware, Oracle has not yet appeared to have made any serious missteps in its journey. Oracle’s only choices were to build—and build big and quickly—or to buy its entry point, although Oracle has been building out its cloud infrastructures with data centers in all the major regions of the world. It also recognized that it is very hard to play catch-up. So, unlike VMware, it decided that this was not to be its only route to market.
Data locality is a feature of some hyperconverged infrastructure (HCI) products. I’m going to spend a couple of articles looking at the implications of having, or not having, this feature. Data locality means that the host running a particular VM should have a complete copy of that VM’s data. Without data locality, the VM data is spread over every host in the cluster. Data locality is not a universal feature, and it can have significant impacts on the scaling of an HCI deployment. In particular, as clusters scale, the storage network can become a bottleneck as the remote IO increases. Working out just how much network traffic took me a little mental gymnastics. The trick is to account for coincidental data locality. The result is that it becomes clear that data locality matters a great deal when you scale your HCI out.
As I think back over the journey from physical, to virtual, to cloud, to containers, there is one technology that stands out—one that has fundamentally moved our mindset away from static resources and has caused a serious shift in how we license, secure, and even think about technology. For me, that shift started the first time I saw vMotion in action (vMotion moves a virtual machine from one host to another without taking the virtual machine down or stopping the running application, and without disaster striking). This one instance shifted my worldview of computing from one in which resources are static to one where they are truly virtual—where the underlying infrastructure in many ways just did not matter. This one technology paved the way for the future of computing.
Thursday marked the closing of the 20th BriForum conference in Boston, Massachusetts, and the end of an era. As the largest independent virtualization industry conference, it’s a place where geeks explain how products really work (or don’t) and where unfiltered side-by-side comparisons are the norm.
Making decisions about IT infrastructure purchases is hard. There are many interlocked decisions to be made, each of which has multiple requirements. Often, a collection of compromises must occur. For the business project owner with little IT knowledge, it may seem far too complicated. It would be great to have tools that simplify these decisions and reduce the work required to make complicated decisions. It would also be useful to have an independent analysis that supports the decisions made.
