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.

HCI Benefits without HCI, Part 2: Policy

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:

  1. Modular, scale-out expansion
  2. No dedicated storage network, no Fibre Channel
  3. 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.

HCI Benefits Without HCI, Part 1: Physical

Do you need to buy an HCI product to get the benefits of a hyperconverged system? I don’t believe that storage and compute need to be on the same physical server to get the big HCI benefits. I think you can get some of the biggest value that HCI delivers without using HCI. The big HCI benefits I see are:

  1. Modular, scale-out expansion
  2. No dedicated storage network, no Fibre Channel
  3. Simplified management

VMware Announces Intention to Acquire Wavefront

On April 12, VMware announced its intention to acquire Wavefront, an innovative startup that provides a solution for monitoring applications in the cloud at scale. Wavefront offers real-time analytics, enterprise-grade frameworks, intelligent alerting, and a comprehensive API. Among its customers are some of the darlings of the SaaS marketspace: Box, Lyft, Groupon, and Yammer, among others.

There is no indication of the costs that are involved. According to the VMware press release, the deal is expected to close in calendar Q2 2017 and will not have a material impact on its financial year 2018.

Docker, Modernizing Traditional Applications

DockerCon 2017 was about modernizing traditional applications, or MTA. MTA is the lifting and shifting of traditional Microsoft Windows base applications into Docker containers. Its approach is reminiscent of 2009. For Docker to grow into brownfield data centers, this is a must. However, could it be doing more? If so, what is it doing that could be improved? MTA is a must for many organizations looking to Docker to manage everything, but not everything uses the same approach. Containers are about agility, with workloads being treated like cattle. Can traditional applications be treated this way? We shall see.

On-Premises Serverless Needs More Services

I wrote a little while ago about running a serverless platform on-premises. I have since realized that there are a few more things that we need before such a platform is useful. Serverless is just a way of doing application code execution. Most applications need more than execution. At minimum, they need some sort of storage and some trigger mechanisms to tie together the execution. A serverless platform by itself will not solve many problems. To enable your developers to use on-premises serverless, you need a few other on-premises services. Applications that use serverless also need storage and web services that integrate with the serverless platform.
