Are Production Server Reboots Standard Changes?

Article | April 27, 2011

I attended a meeting this week with a customer of mine and a potential new vendor. The new vendor was there to pitch his configuration and setup service offerings for a specific ITSM toolset. My customer has already had one bad experience with an ITSM tool configuration vendor who promised one thing and delivered much less. He ended up with a tool that’s minimally used and not configured to match his business needs. He’s looking for a vendor that can understand his business needs and priorities and quickly help him get his tool configured and working in a short time frame. Then the topic of standard changes came up. My customer asked for examples of standard changes. The vendor responded, “Server reboots are an example of standard changes.”

Using Tunneling to Transition to IPv6

Article | Jan. 15, 2013

One of the many useful features of tunneling is to carry non-IP traffic across an IP network, and this is still the case when dealing with IPv6 traffic. This transition mechanism makes use of a configured tunnel to transport IPv6 over a native IPv4 network, which may consist of two sites or more. Unlike the previous transition mechanisms, tunneling is not monolithic; while the basic principles may be similar, the operations are different. The following chart gives a breakdown of the current, major tunneling types in use, particularly in a Cisco environment:

Introduction to Virtual Machines and Hypervisors

Article | April 25, 2013

Organizations of all sizes have identified the benefits of cloud-based computing, whether it’s implementing a private or hybrid cloud on their own or accessing a public cloud through a service provider. Virtualization, a key component for building secure cloud environments, offers many advantages, including higher machine efficiency due to increased utilization, energy savings, and the flexibility to build or destroy virtual machines (VMs) on demand to meet changing organizational needs. Choosing open source virtualization over proprietary alternatives can significantly increase savings. However, an open source Linux Kernel-based virtual machine (KVM) offers several benefits to organizations beyond just cost savings. These benefits include security, reliability, availability, performance, and scalability. In this white paper, we’ll look at the relationship between open source virtualization and the cloud, and explore the security aspects of KVM hypervisor technology, especially in relation to how it leverages SELinux and related capabilities for secure public, private, and hybrid cloud performance.

Virtualization for Newbies: Five Types of Virtualization

Article | Oct. 03, 2013

Although some form of virtualization has been around since the mid-1960s, it has evolved over time, while remaining close to its roots. Much of the evolution in virtualization has occurred in just the last few years, with new types being developed and commercialized. For our purposes, the different types of virtualization are limited to Desktop Virtualization, Application Virtualization, Server Virtualization, Storage Virtualization, and Network Virtualization.

What’s the Value of an AWS Certification?

Article | Feb. 03, 2015

It’s common knowledge that earning an AWS certification is a great way to qualify your experience in the eyes of your peers and employer and to increase your organization’s proficiency with AWS-based applications. However, there is another benefit that has not be quantified until now. Results from the 2015 IT Skills and Salary Survey conducted by Global Knowledge and Windows IT Pro revealed that the average pay of four AWS certifications exceeded $100,000. While there is no guarantee that a certification equals a six-figure salary, it certainly couldn’t hurt.

How To Protect Data in Flight

Article | April 28, 2015

Accessing cloud-based resources, whether they be IaaS/PaaS/SaaS-based, is very convenient. With a browser and Internet connection, you are up and running. No driving to your work office, no need to log into the corporate network. Just open up your web browser and go. This convenience, however, comes with a security risk. All of your business work is conducted over an insecure communication network. Unlike your office network, where the network link between you and the data center is under corporate control and is physically secure, the cloud access link is over the Internet.
