Avoid Virtual Machine Performance Problems from Antivirus Tools

Written by Joe Kozlowicz on Monday, January 9th 2017 — Categories: Cloud Hosting, Hybrid Cloud, Cloud Hosting, Security, VMware

You’re probably familiar with the kind of performance issues inherent in antivirus/antimalware tools. Anyone who has used a PC when the antivirus scan boots up can attest to sluggish performance. The same issues rear their head when using antivirus in a virtual environment – but virtual machines come with their own set of wrinkles.

Antivirus software can be installed either on the VM itself or on the host. Depending on your approach, you’ll want to consider these key factors to maximize performance.

Feeling a VM Resource Squeeze? Practice Active Capacity Management

Written by Joe Kozlowicz on Thursday, November 10th 2016 — Categories: Cloud Hosting, VMware

Cloud infrastructure is all about providing the right amount of resources for your applications at any given moment. Overprovisioning might be wise for performance-oriented apps, but generally “right-sizing” is the best way to maximize your budget, especially as most IT departments face efficiency and cost struggles.

By being proactive about managing your virtual machine resources and halting underutilized or “zombie” VMs, you can free up those resources either to be decommissioned or reassigned to other uses.

You’ll want to adjust VM size to reclaim overprovisioned VMs, clean up idle or turned-off VMs, and resize VMs that are stretching their current resources beyond acceptable performance. Here’s how to practice active capacity management.

When To Use a Container vs. When to Use a Virtual Machine

Written by Joe Kozlowicz on Tuesday, November 8th 2016 — Categories: Cloud Hosting, Software Development, VMware

Containers are on the rise, with VMware integrating them into the vSphere platform. What started seemingly as a competitor to virtual machines has proved to be just another tool in the virtualization box available to administrators beyond software testing and development, as enterprises and mid-market companies of all sizes begin to implement containers alongside (and inside) their VMs.

Once you read a bit about the benefits of containerization, you may be curious about trying some out in your environment. But before you start spinning up containers left and right, make sure you’re using the right tool for the job. Containers certainly have their advantages, but there are many applications where a virtual machine will be more effective. Here’s how to decide.

VMware Snapshot Guide: 8 Tips and Tricks

Written by Joe Kozlowicz on Wednesday, July 6th 2016 — Categories: Cloud Hosting, VMware

Snapshots are a convenient way to get a “moment in time” copy of your virtual machines. They should not be used as a primary method of backup, as they generally work as a record of changes made—they depend on the original virtual machine in order to roll back. They’re great for testing as they save the virtual machine settings, the state of the virtual disks, and the contents of memory, if you choose.

Snapshots are useful before you make significant configuration changes, upgrades, patches, or new software installations. Any time you’re adding or changing your virtual environment enough to think, “Hmm, I wonder if this will affect my production applications,” it’s probably an opportune moment to take a snapshot.

Here are eight tips to make the most of your snapshots.

What Dell’s Acquisition of EMC Means for Partners & Providers

Written by Joe Kozlowicz on Friday, October 23rd 2015 — Categories: VMware

By now you’ve likely heard the news. It is after all the biggest technology acquisition in history: Dell plans to purchase VMware parent company EMC for a whopping $67 billion. While many other industry giants are downsizing and focusing themselves, this will create a behemoth.

What does it mean for service providers who might purchase equipment from Dell or EMC, plus virtualization from VMware? Ultimately it comes down to a balance between competition (vendor neutrality) and the additional resources and integration offered by a one-stop vendor.

Software-Defined Data Centers Put Hybrid Cloud In Your Hands

Written by Joe Kozlowicz on Wednesday, September 16th 2015 — Categories: Cloud Hosting, Hybrid Cloud, Cloud Hosting, VMware

Two of the most buzzworthy IT strategies right now are hybrid infrastructure, especially hybrid cloud, and software-defined data centers (SDDC). With VMware recently throwing its weight behind SDDC technologies and surveys from last year demonstrating that 75% of C-Level executives are focusing on hybrid cloud, these technologies are here to stay.

Gartner reports that only 10-15% of enterprises and mid market organizations are currently using hybrid computing, however. Their report states that, “More advanced approaches…suffer from significant setup and operational complexity.” New software defined data center management could help bridge the gap between interest and implementation.

Together, software-defined technology and hybrid IT help deliver a mobile, highly resilient and easy to manage infrastructure for your business applications and data. Here’s how.

What You Need to Know About VMware’s Photon Container Strategy

Written by Joe Kozlowicz on Wednesday, September 9th 2015 — Categories: Cloud Hosting, Hybrid Cloud, Cloud Hosting, Microsoft, VMware

Last year's VMworld showed the company was serious about making containers work alongside and inside of virtual machines, but with Docker and other container technology continuing to make strides even in the enterprise, VMworld 2015 delivered serious development efforts on VMware's behalf. The result? Photon Platform, a forked version of Linux specifically designed to integrate containers into vSphere, as well as vSphere Integrated Containers.

While containers have been viewed with great interest by the enterprise, they can lack security and integrations with backup and other software. VMware needs a way to solve these problems while also providing a platform to manage containers alongside virtual machines in vSphere.

Here's what you need to know about how these new tools can help you efficiently managed containers in and alongside your vSphere environment.
