Server Virtualization has transformed the way we manage server workloads but
virtualization hypervisors were not the endgame of data center management.
What is the role of server virtualization and hypervisors in the new age of
cloud, containers, and more importantly, hyperconvergence?
I covered SAN technology in my last Infrastructure 101 article, so for today
I'm going to cover server virtualization and maybe delve into containers and
Server virtualization as we know it now is based on hypervisor technology. A
hypervisor is an operating system that allows sharing of physical computing
resources such as networking, CPU, RAM, and storage among multiple virtual
machines (sometimes called virtual servers). Virtual machines replaced
traditional physical servers that each had their own physical chassis with
storage, RAM, networking, and CPU. To understand the imp... (more)
In a series of articles, I am going to share my thoughts on the state of IT
infrastructure and how we've arrived with current architecture trends. The
topic today is SAN.
Storage Area Networking (SAN) is a technology that solved a real problem that
existed a couple decades ago. SANs have been a foundational piece of IT
infrastructure architecture for a long time and have helped drive major
innovations in storage. But how relevant are SANs today in the age of
software-defined datacenters? Let's talk about how we have arrived at modern
First, disk arrays w... (more)
Don't Double-Down on Infrastructure - Scale Out as Needed
There has long been a philosophy in IT infrastructure that whenever you add
capacity, you add plenty of room to grow into. This idea is based on
traditional architecture that was complex, consisting of many disparate
systems held together by the rigorous management of the administrators. The
process of scaling out capacity has been a treacherous one that takes weeks
or months of stress-filled nights and weekends. These projects are so
undesirable that administrators and anyone else involved would rather spend
more than t... (more)
The next generation of platforms is here with options in both cloud and on
premises hyperconverged infrastructure. As IT departments look to move beyond
traditional virtualization into cloud and hyperconverged infrastructure (HCI)
platforms, they have a lot to consider. There are many types of organizations
with different IT needs and it is important to determine whether those needs
align more cloud or HCI. Before I dig into the differences, let me go over
Both cloud and HCI tend to offer a similar user experience highlighted by
ease of use and simplicity. One ... (more)
When it comes to IT infrastructure, there are some big differences in the
needs of the SMB vs the enterprise. What might be minor hiccups in the
enterprise can be major challenges in the SMB. What are these differences and
how should they affect the way solutions are provided?
This is my third and final article in this series. I've covered SAN and
server virtualization and now I'd like to share my thoughts on the challenges
of SMB IT shops vs enterprise IT.
To start, I should probably give some context on the size of an SMB IT shop.
Since we are talking about infrastructure, I am... (more)
