Public Cloud – For the last decade, the cloud computing has been the focus of IT decision makers and corporate IT Heads, but many security-conscious businesses have been hesitant to move data and workloads into the cloud.
Now, with the underlying technology behind cloud services available for deployment inside organisations, a new model of cloud computing is gaining a foothold in business: the hybrid cloud.
What is hybrid cloud?
What customers want to do is simply use multiple clouds – like One or more public clouds connected to something in a data center. That thing could be a private cloud, that thing could just be traditional data center infrastructure.
Hybrid cloud is the combination of one or more public cloud providers (such as Amazon Web Services or Google Cloud Platform) with a private cloud platform — one that’s designed for use by a single organisation — or private IT infrastructure. The public cloud and private infrastructure, which operate independently of each other, communicate over an encrypted connection, using technology that allows for the portability of data and applications.
So in other words .. Hybrid cloud is particularly valuable for dynamic or highly changeable workloads. For example, a transactional order entry system that experiences significant demand spikes around the holiday season is a good hybrid cloud candidate. The application could run in private cloud, but use cloud bursting to access additional computing resources from a public cloud when computing demands spike. To connect private and public cloud resources, this model requires a hybrid cloud environment.
Public cloud’s flexibility and scalability eliminates the need for a company to make massive capital expenditures to accommodate short-term spikes in demand. The public cloud provider supplies compute resources, and the company only pays for the resources it consumes.
So for end-consumer -hybrid is defined cloud as: “Two or more disparate cloud computing environments that are used in conjunction to serve a workload or an application in concert through a single management plane.”
There are tools to manage the same, such as Egenera PAN Cloud Director, RightScale Cloud Management, CliQr’s CloudCenter and Scalr Enterprise Cloud Management Platform help businesses handle workflow creation, service catalogs, billing and other tasks related to hybrid cloud.
The benefits of going hybrid
With the hybrid cloud model, IT decision makers have more control over both the private and public components than using a prepackaged public cloud platform. “you get everything that you want.” This includes increased efficiency and the flexibility to meet disparate needs.
So analysts calls this as “It lets you pick the right cloud for the right workload,”
Building a hybrid cloud with private infrastructure that’s directly accessible — in other words, not being pushed through the public internet — greatly reduces access time and latency in comparison to public cloud services.
Where hybrid doesn’t work
Although hybrid cloud provides several advantages over the public-cloud-only, it still suffers from the same privacy and security issues that plague the popular perception of public cloud platform providers. Allowing information to be transported across a network that can be subject to third-party interference or tapping is, to many organizations, an unnecessary and unacceptable security risk.
Who uses hybrid cloud?
The industries that are moving to hybrid, such as media and finance.
Hybrid clouds are frequently deployed in the financial sector, particularly when proximity is important and physical space is at a premium — such as on or adjacent to a trading floor. Pushing trade orders through the private cloud infrastructure and running analytics on trades from the public cloud infrastructure greatly decreases the amount of physical space needed for the latency-sensitive task of making trade orders. This is crucial for data security, as well. Threshold-defined trading algorithms are the entire business of many investment firms. Trusting this data to a public cloud provider is, to most firms, an unnecessary risk that could expose the entire underpinnings of their business.
Infact, Law firms also utilize hybrid cloud infrastructures with private elements, often as encrypted offsite data stores, to safeguard against the potential for loss due to theft, hardware failure, or a natural disaster such as a cyclones or hurricanes destroying the original documentation or evidence.
So ultimately, our conclusion –
While the upfront cost of server hardware for the private end of the hybrid cloud is high, the control that IT departments can wield over hardware selection and system design for the private component offers an invaluable way of properly tailoring resources to the business’s needs. Assembling a private cloud to handle a standard workload, with burst compute offloaded to the public cloud, can be a long-term budget-friendly arrangement.
Hybrid cloud allows organizations to leverage public cloud services without offloading the entirety of their data to a third-party data center. This provides a great deal of flexibility in computing tasks, while keeping vital components within the company firewall.
