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.
Recalling the 1960s movie David and Goliath, a battle between IT titan Dell EMC and relative minnow Nexsan has been waged in the federal court for the District of Massachusetts over the use of the trademark “Unity.” Both companies market storage arrays branded “Unity.” EMC wrote a cease and desist letter to Nexsan concerning misuse, claiming prior use. However, Nexsan believed that claim to be erroneous, countering that it had filed for the trademark before EMC. It sued the giant for misuse first.
In case number 1:16-cv-10847-WGY in the federal court for the District of Massachusetts, Nexsan’s complaint stated: “EMC has threatened suit unless Nexsan abandons its UNITY trademarks.” Nexsan sought “a declaration that it has priority to, and is not infringing upon, certain trademark rights asserted by EMC Corporation.” The cease and desist order from Dell EMC was an obvious attempt at strong-arm tactics by the storage giant against the smaller company. Dell EMC not only failed to obtain the results it was expecting—this being Nexsan running off scared into the twilight and surrendering its trademark—but also ended up on the wrong arm of a trademark suit.
I had a debate with a fellow technologist at Dell EMC World this year about whether the cloud is more secure than any given data center not used by a cloud provider. The argument put forth was that cloud service providers often have better security controls in place, they can auto-patch systems, etc. All in all, it is a valid argument. However, if I as the tenant cannot prove that security, then whatever the cloud does is not necessarily good enough. With the infrastructure of seventy-four countries impacted by the latest ransomware attack, this debate is placed in stark contrast to reality. Were it not for one researcher, the spread might have been worse. At the moment, the only solution for preventing such widespread ransomware is to upgrade and patch. This does not validate the argument that the cloud will patch for you. It does not do so for many Windows systems (depending on the cloud).
Can you believe we are well into the month of May already? Where does the time go? The end of April is when some of the public cloud companies release their first-quarter earnings. As such, we have some numbers to report on from Amazon, Microsoft, Alibaba, IBM, Oracle, and SAP. The sources I have used for this post are the publicly released company reports, Cleveland Research, Factset Estimates, and CRC Estimates. The SAP numbers have been converted to dollars for the comparisons, and revenues being reported include IaaS and SaaS/PaaS that have been sold on an IaaS platform.
On April 9, 2017, Harry Huskey died at the age of 101. Many of you will most likely be scratching your heads whilst reading this on your screen—either your phone or tablet, or maybe even your desktop device—and you will most likely be asking, “Who, and why should I care, other than knowing somebody’s loved one has passed?”
Software-defined storage (SDS) within the container realm often ignores storage itself. In essence, the SDS platform assumes some chunk of storage is mapped to a container host. Then, it takes over from there. SDS for containers is the orchestration through which persistent storage is mapped to a container. This gives it a unique ability to provide a mount point the SDS layer can control. It also provides a unique view of the world. SDS for containers bypasses traditional storage yet provides for retention, replication, and erasure coding. These are just some of the features, but it does not care what storage is underneath the container host. This assumption could lead to issues down the road, but how does this work?
Hyperconverged infrastructure (HCI) is having a significant impact in data centers around the world. Many IT organizations are getting a lot of benefits from a VM-centered approach to infrastructure. I don’t think that an HCI product is necessary to get these benefits. Most of the benefits of HCI could be delivered by software on top of older architectures. The big HCI benefits I see are:
- Modular, scale-out expansion
- No dedicated storage network, no Fibre Channel
- Simplified management
In a previous article, I looked at the first two, which are both about the physical aspects of hyperconverged infrastructure. Today, I am going to address the third point, which I think is the biggest benefit of HCI.
