Is Hybrid Cloud Just a Stepping Stone to Public?

Written by Joe Kozlowicz on Thursday, October 19th 2017

Hybrid IT infrastructure seems to be the deployment mode du jour, but some theorize that hybrid is just a stopover on the way to a 100% public cloud environment. With cloud adoption as a whole moving slower than many anticipated, it may be too early to definitively say whether hybrid is here to stay, but in our opinion, hybrid will remain a valuable model for many years to come.

Surveys from McAfee and RightScale both show hybrid cloud and multicloud adoption increasing, with McAfee finding a jump from 19% of organizations using hybrid cloud in 2015 to 57% using hybrid cloud in 2016, and RightScale showing an increase from 58% to 71% over the same period.

But are these increases just because hybrid cloud is the easiest deployment model? Often times a company will add cloud resources alongside their current infrastructure, which is considered a form of hybrid cloud. Or is it because the definition of hybrid cloud itself is shifting?

Staying on Top of Resource Commitment with VMware High Availability

Written by Joe Kozlowicz on Thursday, October 12th 2017 — Categories: Cloud Hosting, Cloud Hosting, VMware, Documentation

It’s easy to provision additional VMs and increase resource commitment from your overall resource pool using the vSphere web portal. Maybe too easy. If you overstretch your resources, some features like High Availability failover may not function as planned. HA keeps your VMs from failing by pooling VMs and hosts in a cluster, relaunching failed VMs on alternate hosts.

Overcommitting resources can also lead to general performance problems, so it is in your best interest to use Admission Control to keep a close watch on overall capacity. Another reason? You might be trying to power on new VMs, only to run into errors as you exceed your Admission Control rules. Tweaking them can save you from buying additional host resources.

This post will introduce the concepts of slot sizes and configuration of Admission Control to allow more VMs to move between hosts when you have turned on High Availability in vSphere/vCenter.

How to Decide on a License Model for Virtualized SQL Server

Written by Joe Kozlowicz on Thursday, October 5th 2017

With two different licensing models and several different versions of SQL Server, managing your licensing in a virtualized environment (like a hosted VMware cloud) is no simple matter.

This quick rundown will guide you towards the best licensing choice for your cloud VMs running Microsoft SQL Server.

Know Your Storage Constraints: IOPS and Throughput

Written by Joe Kozlowicz on Thursday, September 28th 2017 — Categories: Cloud Hosting, Cloud Storage, Data Center Design

Application performance can often hinge on how well your storage can serve data to end clients. For this reason you must correctly design or choose your storage tier speed in terms of both IOPS and throughput, which rate the speed and bandwidth of the storage respectively.

It is vital to plan according to manufacturer and developer recommendations as well as real-world benchmarks to maximize your storage (and subsequently application) performance. Take a look at peak IOPS and throughput ratings, read/write ratios, RAID penalties, and physical latency.
