Interfaces for Private and Public Cloud Computing

Public and private cloud computing from the perspective of their different application scope and interfaces

An entire ecosystem is evolving around cloud computing. Interface standardization efforts, commercial products, cloud infrastructure and management services, virtual appliance providers and open-source solutions are filling niches in the cloud ecosystem. The role and position of a component or a service in the ecosystem are defined by its capabilities, the consumers of those capabilities and its relationship with other components and services.

This article presents public and private cloud computing from the perspective of their different application scope and interfaces.

Interfaces for Public Cloud Computing
Public or external clouds
offer virtualized resources as a service, enabling the deployment of an entire IT infrastructure without the associated capital costs, paying only for the used capacity. Amazon EC2,ElasticHostsGoGrid and FlexiScale are examples of commercial cloud providers of elastic capacity, offering a public interface for remote management of virtualized server instances within their proprietary infrastructure. With the growing popularity of these cloud offerings, an ecosystem of tools is emerging that can be used to transform an organization's existing infrastructure into a public cloud. Technologies, such as Globus Nimbus or Eucalyptus, provide an open-source implementation of cloud-like public interfaces, and projects, such as RESERVOIR, are developing open-source toolkits for building any cloud architecture.

The standardization of a public cloud interface is the aim of the OGF Open Cloud Computing Interface Working Group. OCCI-WG is delivering an API specification for remote management of cloud computing infrastructure, allowing for the development of interoperable tools for common tasks on public clouds including deployment, autonomic scaling and monitoring. Main consumers of this API would be service management platforms, technologies for building hybrid clouds, or service providers. The working group keeps a complete list of existing cloud APIs and a list of references to studies comparing the APIs. The requirements for the new specification are being extracted from a collection of use cases contributed by the community. The working group is being supported by relevant companies and open-source initiatives in the cloud computing ecosytem.

Interoperability is not only about standardization of interfaces, but also about portability of virtual machines. The DMTF Open Virtualization Format (OVF) can be used as a means for customers of an IaaS provider to express their infrastructural needs. OVF was not designed with cloud computing in mind, so there are issues that need to be solved when applied to this environment, in particular, on automatic elasticity, self-configuration and deployment constraints. In any case, standards for cloud interoperability (OCCI) and virtual machine portability (OVF) are imminent and many providers are planning to adopt them.

Interfaces for Private Cloud Computing
On the other hand, there is a growing interest in tools for leasing compute capacity from the local infrastructure. The aim of these deployments is not to expose to the world a cloud interface to sell capacity over the Internet, but to provide local users with a flexible and agile private infrastructure to run service workloads within the administrative domain. This private or enterprise cloud model is not new, since datacenter management has been around for a while. In fact, I would venture that  future datacenters will look like private clouds.  Platform VM OrchestratorVMware VSphereCitrix Cloud Center, and Red Hat Enterprise Virtualization Manager are commercial tools for managament of virtualized services on the datacenter, so aimed at building private clouds. OpenNebula Virtual Infrastructure Engine (now part of Ubuntu) is an open-source alternative for private cloud computing, also supporting hybrid cloud deployments to supplement local infrastructure with computing capacity from an external cloud.

Private cloud interfaces should so allow the integration of the virtualized distributed infrastructure in the data-center management stack, including user and administration support. A private cloud interface should provide rich enough semantics, far beyond of that provided by public clouds, to ease this integration. Such interface should provide additional functionality for virtualization, networking, image and physical resource configuration, management, monitoring and accounting, not exposed by pubic cloud interfaces.

The standardization of a private cloud interface may be the aim of the new DMTF Cloud Computing Incubator, given that, according to its charter, one of its benefits is to enable the use of cloud computing within enterprises. The DMTF Open Cloud Standards Incubator Leadership Board currently includes most of main providers and integrators of private cloud solutions. On the other hand, although conceived as a library to interface with different virtualization technologies, the libvirt virtualization API could be also used as interface for private cloud computing. This is the approach represented by the libvirt implementation of OpenNebula. The implementation of libvirt on top of a virtual infrastructure manager provides an abstraction of a whole cluster of resources (each one with its hypervisor), so a whole cluster can be managed as any other libvirt node.

About Using Public Interfaces for Private Cloud Deployments
The usage of public cloud interfaces to access the local infrastructure would reduce the cost of learning a new interface when moving from a private to a public; but at the expense of providing local users with limited functionality, losing the comfort and control of data center operations, and using, within the administration domain, communication protocols and security mechanisms originally created for remote management. Moreover, several local cloud technologies support cloudbursting to build hybrid clouds, so combining local infrastructure with public cloud-based infrastructure and enabling highly scalable hosting environments.

That does not mean, of course, that you can not expose a public interface on top of your private cloud solution. For example if you want to provide partners or external users with access to your infrastructure, or to sell your overcapacity. Obviously, a local cloud solution is the natural back-end for any public cloud.

Predicting the future has never been more challenging - not because of the lack of data but because of the flood of ungoverned and risk laden information. Microsoft states that 2.5 exabytes of data are created every day. Expectations and reliance on data are being pushed to the limits, as demands around hybrid options continue to grow.
Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.
Business professionals no longer wonder if they'll migrate to the cloud; it's now a matter of when. The cloud environment has proved to be a major force in transitioning to an agile business model that enables quick decisions and fast implementation that solidify customer relationships. And when the cloud is combined with the power of cognitive computing, it drives innovation and transformation that achieves astounding competitive advantage.
