Cloud computing is considered one of the most publicized trends in the field of information technology. The reason why it is hyped so high is that a “virtualized” cloud based infrastructure offers several advantages over the traditional datacenter framework in areas of scalability, performance and most importantly, security. As different enterprises develop strategies for executing cloud computing, they face the choice of whether to implement a public or private cloud. Let’s find out what is the difference between the two.
Private Cloud vs. Public Cloud
A public cloud comprises of set of devices or services that are bought by an enterprise from a third party supplier, also known as Infrastructure as a Service (IaaS). These services are provided through the Internet and make use of the processing power and storage capacity of the host. A private cloud, on the other hand is built using the resources of the enterprise. This gives you complete control over the cloud but you do have to shoulder the management over-head.
Some examples of public cloud services that we commonly use are: Gmail, Microsoft Office 365 and Dropbox. A public cloud provider hosted services are available to everyone on the Internet. Amazon Web Services (AWS) is one of the largest public cloud providers, followed by companies such as: Rackspace, Microsoft, Google and more.
In a Private Cloud, instead of offering metered services to everyone, the services are offered to customers, organizations and departments within an enterprise.
What we can conclude from this is that if you are running a private cloud, you are physically managing all the devices and operating the entire infrastructure, including billing-software and instant deployment of the services. For those who see value in adopting private cloud, the next question is “Can a private cloud be implemented without the hassle of underlying hardware?”
Well, this is indeed possible, thanks to virtual private cloud (VPC). A VPC is a compelling alternative to the traditional private cloud solutions. Instead of the hardware, VPC focuses on resources therefore increases performance and productivity by reducing the cost. The key benefits of a VPC are:
· Scalability: You can add multiple resources to accommodate increasing number of users and scale up and down depending on the workloads.
· Automation: The manual process is transferred to virtual machines.
· Security: You have the privilege to set policies to allow only the specified users access to the cloud resources and traffic from and to the cloud infrastructure stays within the company’s firewall.
· Performance: As a result of scalability and automation, the productivity is increased immensely. Now you have the resources available on demand and infrastructure to support these resources is readily available.
· Control: Similar to a Virtual Private Network (VPN) which provides secure transfer of data over internet, VPC provides secure transfer of data between an enterprise and public cloud. You have complete control over your cloud’s incoming and out going traffic as well as the information stored in Public cloud
Virtual Private Cloud offer companies a viable information technology solution (http://fortycloud.com/). The enterprises that are looking to migrate towards private cloud; a VPC could be the safest and most secure way. It is a flexible solution that can be utilized in any workspace and help enterprises streamline in the most secure environment.
