Yesterday we heard about several purchases within the industry: Microsoft’s acquisition of LinkedIn, Symantec’s purchase of Blue Coat, and VMware’s acquisition of Arkin. These are not small purchases. Once integrated, they start the journey to bigger goals and dreams. As some put it on Twitter, “It is a big day in IT.” I would agree. What is the reason for each of these purchases, and why have they been made? The oddest one, which has people scratching their head, is Microsoft’s purchase of LinkedIn.
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.
Have you heard about unikernels? A unikernel, or cloud operating system, as it has also been called, is a specialized lightweight operating system intended to be used within a virtual machine. Unikernels have the potential to become the core of a new form of cloud computing in which a single hypervisor instance can support hundreds or even thousands of virtual machines. A rethinking of how we populate the cloud infrastructure, the unikernel is a specialized, single-address-space virtual machine image constructed by using a virtual library operating system.
Cloud this, cloud that…it seems that the cloud will heal all your woes. But will it really? Some vendors are using the term “cloud” to signify various services, such Software as a Service (SaaS), private cloud, public cloud, hybrid cloud, and more. With so many clouds, how can you be sure that you’re getting the right cloud for you or whether you even need a cloud?
How much is your data worth? How much does it cost to store your data? I doubt that you have numbers for either of these things. But maybe it is time to start thinking carefully about both of these numbers. If the cost of storing your data exceeds its value, then you probably shouldn’t be storing the data. The trigger for this thought is the oncoming Internet of Things (IoT) data tsunami. A few guestimates I’ve seen suggest that we will see around 50 Zettabytes (ZB) of data generated in the next five years. That is 50 Million Terabytes. One place to store 50ZB of data is on AWS’s cheapest storage, Glacier. At the cheapest published price for Glacier, your monthly bill would be over half a billion dollars. I wonder whether knowing the temperature inside my refrigerator every minute of the day is worth that much money.
The IT industry is abstracting everything it can, from hardware, to networking, to storage and more. “Abstract and build an API, and the world becomes better” seems to be the motto. Abstraction has become the goal of many subsystems. Many people seem to believe that if you move everything to software, everything will be better—and that if you use the API, things will move faster. This is all true, up to a point. Abstraction is a good thing, and we are now seeing levels of abstraction even within the hardware itself. This is also a good thing.
