Where would you take your cloud if storage wasn’t a barrier? It’s a question we’ve been asking a lot around here — of ourselves, of our customers, and more broadly, of enterprises and service providers across the board.
Yes, cloud computing is big, practically standard procedure for IT computing operations. But steadily nudging its way forward is private cloud, and a drive toward delivering Infrastructure as a Service (IaaS) to internal “customers.” According to RightScale’s 2015 State of the Cloud Survey:
“Only 13 percent of enterprises are running more than 1,000 virtual machines (VMs) in public cloud, while 22 percent of enterprises have more than 1,000 VMs in private cloud.”
In Ovum’s November 2014 report, “The Role of Cloud in IT Modernisation,” it is predicted that by 2016 over 80% of enterprises globally will deploy IaaS, with investments in private cloud computing showing the greater growth.
What is the intrigue? The attributes of private cloud make it a compelling infrastructure model for large enterprises that want or need to keep business-critical data and applications under their control. Self-service, dynamic scalability, shared resources, usage analysis, and protocol standardization are distinct characteristics stimulating the wave of private cloud deployment. Cloud services have shown just how responsive and self-service oriented IT delivery can be, and more and more companies are looking to emulate this flexibility, scale, and automation inside their firewalls.
If you’re stepping into the private cloud foyer for the first time, or have been contemplating it for a while but aren’t sure whether your organization is in the right place to make a move, I encourage you to have a quick read through Private Cloud: A Compelling Infrastructure Delivery Model.
The article highlights five substantiated benefits that arise from going private in the cloud:
1. Using resources as services
Private clouds enable a service model to end users, giving them greater flexibility over obtaining IT resources and enabling those resources to be obtained programmatically. End users are abstracted from the underlying technologies used to provide the services, allowing them to focus on development needs rather than how best to carve off an adequate piece of IT infrastructure.
2. Flexibility and scale
When services are scalable and elastic, resources can be added or removed as needed to better enable dynamic business demands. This eliminates complex advanced capacity planning, because resources can be spun up and used as needed.
3. Resource sharing
Because developers often overestimate the resources they need, they may inadvertently under- or over-provision their resource request. This can lead to inefficient resource usage, where provisioned infrastructure sits idle waiting to be used, even though other development groups may have an acute need for it. When IT silos are consolidated into a private cloud, they can be shared, helping build economies of scale. Fewer islands of infrastructure reduce capital outlays and minimize the operational expenses associated with managing disparate systems. Infrastructure can be used most efficiently and serve the needs of multiple users simultaneously.
4. Measurement and payment
Private clouds enable showback ― a quick way for companies to understand how infrastructure is being used by business units, and how that usage is translating into cost. Companies doing actual chargeback can adjust infrastructure expense based on usage, helping drive costs down and increase resource utilization.
5. Use of Internet protocols and technologies
In non-cloud environments, interaction with infrastructure is via non-standard, proprietary ports and protocols, which often require third-party management. Cloud deployments are maintained over Internet protocols, such as HTTP. Because clouds are delivered via Internet protocols, code can be written to them via APIs. All you need is a standard API client to maintain your cloud infrastructure.
