What Is Private Cloud?

Cloud = Virtualization + Automated & Managed Provisioning + Integrated Billing

I was on a LinkedIn thread titled ‘How cloud computing is different from SaaS‘ where Rick Chapman who runs SoftLetter and SaaS University went on beating on this question ‘What is a private cloud’? It is definitely worth it given the tremendous amount of confusion in the term ‘Cloud’ in general and ‘Private Cloud’ in particular. The motivation for this post is Rick and supported by a tweet I read around the same time from ‘Carl Brooks‘ who is a technology writer on Cloud at TechTarget.  Let me give it a shot.

Private Cloud Tweet Post by Carl Brooks

First, Cloud is about leveraging economies of scale whether it is public or private. Large companies like Citi Bank, P&G, Unilever, Pfizer have the economies of scale to create an equivalent of ‘Amazon EC2′ within the corporate network.When most people refer to ‘Private Cloud' they are thinking about Virtualization.

Private Cloud != Virtualization.

To me,

Cloud = Virtualization + Automated & Managed Provisioning + Integrated Billing

If you have this type of infrastructure inside your corporate network then you can proudly call you have a ‘Private Cloud'. However, most companies are using Virtualization - at least all the large ones - and I see some of them say they are already in Cloud during the networking sessions @ conferences. Just doing Virtualiztion alone does not qualify to be called as Private Cloud!

If and when the ‘Data Centre' in enterprise IT, starts offering services to various internal departments and divisions (IT and/or Business), the same way Amazon EC2 does for public customers, with a fully managed provisioning, integrated billing leading to pay for what you use then they can call themselves ‘Private Cloud'. If you are small company running 25 servers, all you can do is Virtualization - not ‘Private Cloud'

I know this is not going to end here. Preparing myself to tackle the attacks... :-) !

You know you need the cloud, but you’re hesitant to simply dump everything at Amazon since you know that not all workloads are suitable for cloud. You know that you want the kind of ease of use and scalability that you get with public cloud, but your applications are architected in a way that makes the public cloud a non-starter. You’re looking at private cloud solutions based on hyperconverged infrastructure, but you’re concerned with the limits inherent in those technologies.
For organizations that have amassed large sums of software complexity, taking a microservices approach is the first step toward DevOps and continuous improvement / development. Integrating system-level analysis with microservices makes it easier to change and add functionality to applications at any time without the increase of risk.
