    Hey, I'm James. I've been a self-employed business network and server admin for 21+ years. I've worked with all flavors of Linux and Windows for some of the best businesses in the country. My average customer that I've worked with has been with me over 10 years. I specialize in analyzing current infrastructure and determining the needs of my clients then providing a written plan to correct any issues and protect the business systems from hackers and cryptolockers. In one of my recent projects, I consulted with a six billion dollar, publicly traded company to completely redesign their infrastructure to have redundant firewalls, VMWare host servers, leased fiber lines directly to Amazon AWS with a VPN backup over a regular Internet circuit that would automatically fail over in case of any circuit issue. The vmware servers would auto migrate the guests in the case of overload or host server failure. All power systems were redundant with two powersupplies for each piece of equipment. At the end of this project, we had reduced their monthly cost of management by over 25,000 per month and reduced their server load from over 20 servers to just 8 servers. When you hire me, here's what you can expect: 1. First, click the invite button to invite me to your job. 2. Once everything is accepted, I'll jump on the phone or a zoom with you 3. We'll go over the details of the job and I'll ask questions to drill down to the specific goals you want to accomplish. 4. I'll provide you with a high level written plan to address your goals along with expected time needed to complete your project. 5. When we agree on the timeline and process, I will execute the plan. So, if this sounds good, just click the "invite" button and we can start.

Spotlight on Server Technology: What Is Virtualization?

One important evolution in server technology is virtualization, which has become an almost ubiquitous way to program servers to be more efficient. In this article, we’ll look at how it works and why it’s so important for networks running multiple applications.

What is virtualization?

Virtualized servers have outweighed physical servers for decades—an important concept that’s been put to use since the 1960s. So what does it mean and how does it save you time, money and resources?

Virtualization is a method that takes a single server and divides it into many smaller, “virtual” server environments. It’s standard practice in server architecture and allows one physical server to take on a bunch of tasks, while consolidating hardware and maximizing resources. With virtualization, you’re not limited to housing just one application per server. You can host a number of applications all on one machine within separate environments that are encapsulated apart from the core operating system.

If a traditional server is a 1:1 ratio (1 machine: 1 operating system), virtualization creates a 1:many ratio. All of a sudden, that single server is getting a lot more done at once. Need to scale up and create a large number of virtual machines quickly? Virtualization makes that easy, too. You can standardize how you program your smaller virtual servers and then rapidly roll them out when needed. You can also migrate between servers without downtime, which is another time-saving bonus.

Think of a server like a building with different floors. The first floor lobby is the server’s operating system. On top of that is the second floor, a software layer that’s broken into rooms—the smaller, individual servers with their own operating systems. Sometimes, there’s even a third floor, broken into more, even smaller rooms.

Harware vs. software virtualization

There are also different approaches to virtualization. First, there’s hardware partitioning (or hardware-assisted virtualization), where the computer’s CPU is augmented (e.g., with a chip) to take on common tasks and speed things up. That’s like adding a separate, faster elevator line in the lobby for regular visitors. Then, there’s software virtualization, which creates those second and third-floor rooms that house the smaller operating systems.

An important component of this is the hypervisor (or, virtual machine manager [VMM]), a layer of software that creates and runs these “guest” operating systems. They’re like the building’s floor plans and utilities, and they can either run directly on the hardware (Type 1, which is most efficient because it has direct access to the hardware), or they can run on top of the existing OS (Type 2, one layer up). Type 2 hypervisors are also known as paravirtualization, and are a bit less efficient, but have been improved by extensions over the years.

In addition to getting more done at once on the same machine, virtualization is helpful for maintenance, application security, scaling up, and provisioning, because the environments are isolated from one another.

Virtualization in the cloud

Virtualization has made a lot of what we do in the cloud (and hybrid cloud) possible. It’s become a large aspect of how we deploy operations to the cloud because it provides a layer of abstraction that’s essential to distributed environments. But it’s not without it’s challenges. Virtualizing in a hybrid cloud environment, for example, means that you could have a collection of different virtual machines running across public and private clouds, each hosting unique services. The complexity of ensuring the security of a multi-layered, virtualized environment in a hybrid cloud situation increases right along with the complexity of the set-up, so be sure to plan for IT security, data security, and virtual network monitoring.
