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.
I noticed a tweet recently by a person I respect, Craig Kilborn. Craig had just written a blog post about why he was pleased that he didn’t pass the defense part of the VCDX. The arguments he made in the article were cogent, and I found myself agreeing with them. They aligned with my view of the worth of the VCDX certification to me personally.
I have not traveled down the VCDX path as far as Craig has, but I find myself pondering the value of the certification today. There is no doubt that the journey towards the certification is a valid one and, more importantly, a valuable learning experience. All those I have spoken to who have traveled the path, whether they gained their number or not, have grown as IT professionals.
When we think about networking, we think about things that go bump in the wire—things that place bumps in the wire. Such things could be switches, load balancers, firewalls, routers, gateways, etc. The list is not all that long, thankfully. Things that put bumps in the wire are at odds with software-defined networking (SDN). SDN relies upon key services to exist. These services are DNS, identity management, and key management. Without these, many systems would fail outright. However, they are not considered network functions. Network functions are considered to be the bumps in the wire we need to make applications work. The goal of network functions virtualization (NFV) is to streamline this process, to reduce complexity while maintaining compatibility. NFV and SDN together lead to an interesting mix of hardware and software, and some of these just do not interoperate well. Is there a better solution?
I will admit, I was surprised recently to discover that VMware has announced the end of life of its third-party virtual switches (vSwitch). These have been a part of the vSphere ecosystem for many years now. This relationship with other vendors seems to be coming to a close.
In a discussion I had yesterday, I noticed that the networking world still has many arbitrary boundaries. It is what we do: create boundaries where none really exist. We do this to cut a problem down to size. Yet when that itself becomes the problem, we end up with design decisions based on our boundaries. We need networking, specifically software-defined networking, to ignore most boundaries. We need to move away from terminology that imposes those boundaries upon our designs. Virtualization is about breaking silos, not imposing them. Network virtualization needs to do the same.
In a not-too-unexpected move, VMware has announced the sale of its Public Cloud division. It is well-known that vCloud Air has been struggling. In a deal expected to close in Q2 2017 they have offloaded it to French Cloud hosting provider OVH. OVH defines itself as one of the largest cloud service providers in the world, with 1 million customers and 260,000 servers deployed, so roughly a quarter of a server per customer. I am pretty sure that Oracle, AWS, Google, and Azure are bigger, but there you go. Marketing at its best — OVH, one of the largest cloud service providers in the world.
Once the deal has gone through, OVH will rebrand the service as “vCloud Air Powered by OVH.” In addition, OVH will be shutting down vCloud Air’s pay-as-you-go service, ending the consumption model.
Along with HPE’s acquisition of Nimble Storage (see my article News from the Storage World), earlier this year HPE also acquired the second-place hyperconverged infrastructure startup company SimpliVity. I think HPE comes out way on top in these acquisitions, as HPE gives the appearance of setting the stage for vendors to dominate the hyperconverged market where the Art of Business will play out.
