Cloud computing, while a very hot area right now for scaling IT infrastructure, isn’t new. Amazon.com introduced the Elastic Compute Cloud back in 2006. Compaq, which merged with HP in 2002, was discussing the seeds of modern cloud computing in 1996. Dig back even further to 1977, and you’ll find ARPANET using cloud-like symbols.
While cloud computing has a number of compelling IT- and business-advantages, one of its biggest downsides is its public, shared nature. This means limited control over a variety of factors including location, performance, security, management, and cost escalation.
Private cloud, contrary to public cloud — what most simply refer to as cloud computing, is often a much better fit for many business models, industries, end users, and IT teams.
Private Cloud Defined
Private cloud is a dedicated set of IT computing resources, for a particular organization, that is delivered in a service model. When you contract for private cloud services, you pay either a monthly or other recurring fee. And you don’t have any capital investment, or anything like that, to get the environment up and running.
Typically, a private cloud installation leverages virtualization technology of some sort, whether it’s VMware or Hyper-V or something like KVM OnApp.
With private cloud infrastructure, there’s high availability built into the environment. You have some redundancy if a particular node fails, so that all of your virtual machines (VMs) will fail over. You have the ability to migrate workloads from one hypervisor to another, so you can do maintenance on a hypervisor in a nondisruptive manner.
Private Cloud Vs. Public Cloud Vs. Hybrid Cloud
Given that public cloud is often the default choice by less sophisticated, or less discriminating IT buyers, what’s the difference between private cloud, public cloud (again, what most think of when talking about cloud computing), and hybrid cloud?
With public cloud, we’re usually talking about Amazon Web Services (AWS), Google Cloud, IBM Cloud, and Microsoft Azure.
In a public cloud environment
- resources are not dedicated to you
- billing models might be by the hour, by the day, or by the month
- spot instances are available for purchase at a discount, where you can bid on spare Amazon EC2 capacity
In a private cloud environment, all of the resources are dedicated to you and your needs. Depending on what your workloads look like, this could be a good thing or a bad thing.
If you have fairly static workloads that are consistent and reliable and you don’t need a huge amount of burstability, you could probably find a lot of savings and additional security using a private cloud model.
A hybrid cloud environment is some combination of on-premises infrastructure (at your location), private cloud infrastructure, and public cloud services .
One of the big differentiators Handy Networks brings to any kind of cloud computing environment is that Handy Networks bolts on white glove management services on top of its vendor agnostic infrastructure.
When you move your IT infrastructure to Amazon Web Services or Microsoft Azure, you’re literally just buying infrastructure as a service (IaaS). You’re not getting any backups, data protection, disaster recovery, management, or monitoring services.
