Benefits of Private,Public and Hybrid Cloud Computing
Cloud computing has traditionally broken down into two models namely Private and Public. The difference between the two lies in who maintains control and responsibility for the data-centre and is ultimately responsible for ensuring application service levels are met. For all intents and purposes the cloud computing market appears to be thriving. But while the experts continue to claim it’s the way of the future, tech infrastructure run on businesses’ premises is far from dead.Cloud computing is fundamentally changing the way we think about computing and has allowed Information Communications Technology to be delivered over the internet and be consumed as a service, on demand, across a wide range of devices.This new business model has enabled organizations to adopt productivity enhancing ICT services at a lower cost and with greater ease. Research from around the world continues to link the adoption of cloud services with economic growth and more successful businesses.In public cloud computing, some or all aspects of operations and management are handled by a third party service provider.
Public clouds benefits includes low costs and scalability that comes in handy and are extremely useful for companies needing to deal with large amounts of data or for those that do not have the resources to manage their own infrastructure.On the other hand, eyebrows have been raised about how secure public clouds are, and where the data they hold is physically stored, an issue that has been a major concern from a regulatory perspective.As a result, public clouds are often thought of as being suitable primarily for non-sensitive applications or data.When it comes to private cloud, there are different set of benefits in comparison to public cloud. The private cloud model is based on the data-centres being owned and maintained by the organization using them. What that means is businesses have the ability to create a virtualized IT infrastructure that prepares them for the future, is built on an organization’s own terms, and still maintains the flexibility and scalability of cloud-based applications. Unlike the public cloud, private cloud computing does require an organization’s own IT team and sufficient resource, which can sometimes prove impractical for micro companies.
Last year, Verizon Enterprise Solutions, a US firm released its State of the Market: Enterprise Cloud 2014 report, based on a survey of almost 200 of its own customers and drawing on research from the likes of the Boston Consulting Group, Harvard Business Review Analytic Services, Accenture, Forrester Research, Gartner and IDC.Verizon concluded: “The trend is clear: cloud is now mainstream. It’s become an established delivery platform for application workloads, alongside more traditional delivery mechanisms, such as co-location, managed hosting and on-premises data-centres.”It added: “Across industries and regions, many organizations are approaching the allocation of workloads with a ‘cloud first’ mindset.”Verizon reported 66 per cent of companies were either “concerned or very concerned about the complexity involved in managing and governing a hybrid cloud environment”.Research has shown that cloud computing is now mainstream and is being adopted not simply for expediency and cost savings, but to meet strategic IT and business goals.Multinational corporations are increasingly looking to leverage the power of all three forms of cloud services private, public and hybrid for various mission-critical business applications, and needed third party assistance to integrate these successfully.Large companies are focusing on cloud integrators that can help them manage change and scale rapidly.
Private and public clouds bring their own unique advantages and disadvantages, and many companies may require elements of both. As a result, a third option has become increasingly popular as it combines the best of both models; hybrid clouds.Hybrid clouds is a fusion of both public and private clouds qualities, allowing companies to take advantage of both cloud models in a way that works best for their businesses, now and in the future. Hybrid cloud models can provide both private and public services as an integrated service while individual cloud providers offer a complete hybrid package. Organizations which manage their private clouds themselves sign up to a public cloud service which they then integrate into their infrastructure.It works very well if a company uses a public development platform that sends data to a private cloud or a data center–based application or when a company leverages a number of Software as a Service applications and moves data between private or data center resources as well as when a business process is designed as a service so that it can connect with environments as though they were a single environment.As I have argued before, as small firms mature, the right cloud solution can help ensure that number only decreases.Finding the right balance between the business’s long and short-term goals and resources available can be a huge challenge.
