Five Private Cloud Pitfalls

But just because it’s private doesn’t mean it’s not susceptible to its own range of pitfalls

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.

Private cloud may be the right choice for you, though it is not without its potential pitfalls.

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.

Most companies are adopting or evaluating container technology - Docker in particular - to speed up application deployment, drive down cost, ease management and make application delivery more flexible overall. As with most new architectures, this dream takes a lot of work to become a reality. Even when you do get your application componentized enough and packaged properly, there are still challenges for DevOps teams to making the shift to continuous delivery and achieving that reduction in cost ...
API Security has finally entered our security zeitgeist. OWASP Top 10 2017 - RC1 recognized API Security as a first class citizen by adding it as number 10, or A-10 on its list of web application vulnerabilities. We believe this is just the start. The attack surface area offered by API is orders or magnitude larger than any other attack surface area. Consider the fact the APIs expose cloud services, internal databases, application and even legacy mainframes over the internet. What could go wrong...
The goal of Continuous Testing is to shift testing left to find defects earlier and release software faster. This can be achieved by integrating a set of open source functional and performance testing tools in the early stages of your software delivery lifecycle. There is one process that binds all application delivery stages together into one well-orchestrated machine: Continuous Testing. Continuous Testing is the conveyer belt between the Software Factory and production stages. Artifacts are m...
Web services have taken the development world by storm, especially in recent years as they've become more and more widely adopted. There are naturally many reasons for this, but first, let's understand what exactly a web service is. The World Wide Web Consortium (W3C) defines "web of services" as "message-based design frequently found on the Web and in enterprise software". Basically, a web service is a method of sending a message between two devices through a network. In practical terms, this ...

In IT, we sometimes coin terms for things before we know exactly what they are and how they’ll be used. The resulting terms may capture a common set of aspirations and goals – as “cloud” did broadly for on-demand, self-service, and flexible computing. But such a term can also lump together diverse and even competing practices, technologies, and priorities to the point where important distinctions are glossed over and lost.
Enterprise architects are increasingly adopting multi-cloud strategies as they seek to utilize existing data center assets, leverage the advantages of cloud computing and avoid cloud vendor lock-in. This requires a globally aware traffic management strategy that can monitor infrastructure health across data centers and end-user experience globally, while responding to control changes and system specification at the speed of today’s DevOps teams. In his session at 20th Cloud Expo, Josh Gray, Chie...

All organizations that did not originate this moment have a pre-existing culture as well as legacy technology and processes that can be more or less amenable to DevOps implementation. That organizational culture is influenced by the personalities and management styles of Executive Management, the wider culture in which the organization is situated, and the personalities of key team members at all levels of the organization. This culture and entrenched interests usually throw a wrench in the work...
As many know, the first generation of Cloud Management Platform (CMP) solutions were designed for managing virtual infrastructure (IaaS) and traditional applications.

When you focus on a journey from up-close, you look at your own technical and cultural history and how you changed it for the benefit of the customer. This was our starting point: too many integration issues, 13 SWP days and very long cycles. It was evident that in this fast-paced industry we could no longer afford this reality. We needed something that would take us beyond reducing the development lifecycles, CI and Agile methodologies. We made a fundamental difference, even changed our culture...
Docker is sweeping across startups and enterprises alike, changing the way we build and ship applications. It's the most prominent and widely known software container platform, and it's particularly useful for eliminating common challenges when collaborating on code (like the "it works on my machine" phenomenon that most devs know all too well). With Docker, you can run and manage apps side-by-side - in isolated containers - resulting in better compute density. It's something that many developer...
