Understanding Cloud Services: Public, Hosted, and Internal Clouds Defined

Like any new business technology, the early development of cloud services can be a little confusing

Like any new business technology, the early development of cloud services can be a little confusing -- as some descriptions are still open to interpretation. However, the dialog is helpful, because it enables us to focus on the true business value of data center resources.

According to Forrester Research, cloud computing platforms are more than shared multi-tenant infrastructures on the public Internet. There are three infrastructure-as-a-service (IaaS) cloud deployment options available; each has unique characteristics and economics.

Forrester’s three cloud service scenarios follow:

Which cloud service scenario is a best-fit for your business needs? Well, that depends upon a number of related factors -- such as your organizational bias for direct control, sensitivity to risk, and overall usage requirements for a cloud computing platform.

Public Cloud Scenario
Public clouds are easily accessible, multi-tenant virtualized infrastructures that are managed via a self-service portal. They deliver superior economies of scale to customers, as the infrastructure costs are spread among all users, giving each individual client an attractive low-cost, pay-per-use model.

They are managed and supported by the cloud provider and are typically homogeneous, meaning all customers share the same pool of infrastructure with limited configuration, security protections, and availability variances.

Internal Cloud Scenario

Internal clouds have similar characteristics of a public cloud, but hosted within your own data center. They leverage more of your standard processes and protections, but tend to be limited in size and scale. Your IT organization must incur the full capital and operational costs for the physical resources.

They are best for applications where you want complete control and configurability of the infrastructure and security. This most often applies to applications that manage sensitive information that is subject to strict compliance standards.

Hosted Cloud Scenario
Hosted clouds are hybrids -- a multi-tenant cloud atop rented resources, but dedicated to a single client. They help you avoid the capital and operational expense of an internal cloud, growing and shrinking the size of the cloud as needed by simply renting more resources (often added via a pay-per-use model) but providing more custom SLAs.

They give you more flexibility, where you can adjust the security as needed, specify the infrastructure elements to be used, the SLA to be applied, and set other constraints not available on a shared public cloud.

Plus, the cloud is managed by a Service Provider -- rather than your IT team. However, the economics of hosted clouds are more like managed hosting than public clouds -- since the servers that make up the cloud are typically fully dedicated to you.

Evolutionary Pathway to Cloud Services
Forrester concludes that cloud services are infrastructure deployment options that help businesses better match the needs of the application with computing resources. It’s the integration between these infrastructures that delivers the greatest value.

The goal is to speed IT service delivery, while reducing costs. Therefore, consider all options. Ask your service provider to explain their offerings, and if they can provide a pathway to virtual private cloud services -- between your data center and their cloud infrastructure.

"NetApp's vision is how we help organizations manage data - delivering the right data in the right place, in the right time, to the people who need it, and doing it agnostic to what the platform is," explained Josh Atwell, Developer Advocate for NetApp, in this SYS-CON.tv interview at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.
TCP (Transmission Control Protocol) is a common and reliable transmission protocol on the Internet. TCP was introduced in the 70s by Stanford University for US Defense to establish connectivity between distributed systems to maintain a backup of defense information. At the time, TCP was introduced to communicate amongst a selected set of devices for a smaller dataset over shorter distances. As the Internet evolved, however, the number of applications and users, and the types of data accessed and...
DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm. In their Day 3 Keynote at 20th Cloud Expo, Chris Brown, a Solutions Marketing Manager at Nutanix, and Mark Lav...

The Jevons Paradox suggests that when technological advances increase efficiency of a resource, it results in an overall increase in consumption. Writing on the increased use of coal as a result of technological improvements, 19th-century economist William Stanley Jevons found that these improvements led to the development of new ways to utilize coal. In his session at 19th Cloud Expo, Mark Thiele, Chief Strategy Officer for Apcera, compared the Jevons Paradox to modern-day enterprise IT, examin...
The Software Defined Data Center (SDDC), which enables organizations to seamlessly run in a hybrid cloud model (public + private cloud), is here to stay. IDC estimates that the software-defined networking market will be valued at $3.7 billion by 2016. Security is a key component and benefit of the SDDC, and offers an opportunity to build security 'from the ground up' and weave it into the environment from day one.

Many organizations are now looking to DevOps maturity models to gauge their DevOps adoption and compare their maturity to their peers. However, as enterprise organizations rush to adopt DevOps, moving past experimentation to embrace it at scale, they are in danger of falling into the trap that they have fallen into time and time again. Unfortunately, we've seen this movie before, and we know how it ends: badly.
Kubernetes is a new and revolutionary open-sourced system for managing containers across multiple hosts in a cluster.
