There are many reasons to trust the private cloud – from reliability, to security and compliance, to predictability, private cloud can often be the best choice for a business.
But just because it’s private doesn’t mean it’s not susceptible to its own range of pitfalls. While the shortcomings of public cloud have been widely discussed, it’s important to note that private clouds, too, are associated with a range of potential pitfalls you ought to be aware of.
1. Virtualization and cloud are not the same
While virtualization is a component of a cloud environment, to be virtualized alone does not constitute cloud. An IT department must define those differences right off the bat, Network Computing’s Ericka Chickowski notes.
2. Faux ‘private clouds’
Related to understanding the difference between virtualization and cloud, knowing what constitutes a true private cloud is integral to understanding what you should be paying for. Many would argue that private cloud has a broader definition. However, we would argue that cloud is a service you pay for, not something you buy and install internally. The shift away from capital expenditure important to consider, particularly as you think about which parts of your business could be made better with less of an emphasis on internal maintenance of infrastructure.
3. Know your workloads now, with a mind for later, too
A private cloud is not the public cloud. With the former, scaling occurs in a much more thoughtful and planned way. With private cloud, it’s best to prepare in advance — consider utilizing existing resources or upgrading as necessary. Understanding the outside limit of what a workload or application will require is a good starting point, but one of the virtues of the private cloud is the ability to more actively predict costs associated with infrastructure. Plan ahead, realizing that success incurs additional usage.
4. Performance expectations
Performance should be a deciding factor as to whether you choose a private cloud. For example, what if the storage on the back end of the outsourced private cloud is shared? While this might be fine some businesses, and while the cloud provider may even guarantee scalability, what if you require 100 terabytes of storage right off the bat? In that case, such an arrangement would not make sense. Be sure to ask about shared vs. dedicated resources.
5. When not to go private
Whether you are thinking about security, compliance, or performance, there are reasons to go to private cloud. However, related to understanding your workload necessities, if you need to speedily spin up resources at a tremendous scale, then private cloud is probably not the right choice. If your business encounters (or expects to encounter) tremendous spikes in usage, having a private cloud may even be detrimental to meeting that demand. It takes longer to provision resources in a private cloud deployment, whereas with a public cloud you can automate scaling requirements on demand.

This is a no-hype, pragmatic post about why I think you should consider architecting your next project the way SOA and/or microservices suggest. No matter if it’s a greenfield approach or if you’re in dire need of refactoring. Please note: considering still keeps open the option of not taking that approach. After reading this, you will have a better idea about whether building multiple small components instead of a single, large component makes sense for your project. This post assumes that you...

Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...

Adding public cloud resources to an existing application can be a daunting process. The tools that you currently use to manage the software and hardware outside the cloud aren’t always the best tools to efficiently grow into the cloud. All of the major configuration management tools have cloud orchestration plugins that can be leveraged, but there are also cloud-native tools that can dramatically improve the efficiency of managing your application lifecycle. In his session at 18th Cloud Expo, ...

Let's just nip the conflation of these terms in the bud, shall we?
"MIcro" is big these days. Both microservices and microsegmentation are having and will continue to have an impact on data center architecture, but not necessarily for the same reasons. There's a growing trend in which folks - particularly those with a network background - conflate the two and use them to mean the same thing.
They are not.
One is about the application. The other, the network. T...

Before becoming a developer, I was in the high school band. I played several brass instruments - including French horn and cornet - as well as keyboards in the jazz stage band. A musician and a nerd, what can I say? I even dabbled in writing music for the band. Okay, mostly I wrote arrangements of pop music, so the band could keep the crowd entertained during Friday night football games. What struck me then was that, to write parts for all the instruments - brass, woodwind, percussion, even k...
