A VPN, or Virtual Private Network, is basically a secure tunnel from one location to the next. When you VPN into your home network you will essentially look like you are connected to and inside your home network, able to access all the devices attached to that network just as if you were at home.
Cloud resources on the other hand are basically just standard routing from one computer on a network to another computer “in the cloud” usually most are going to still use some type of encryption for your login access and other data being passed across the network to the cloud but usually does not involve the need for a VPN of any sort “into the cloud” so to speak.
What Is a Cloud VPN?
A cloud VPN (aka a virtual private network as a service or hosted VPN) is a new type of VPN technology that’s specifically designed for the cloud. Cloud Storage is a service where data is remotely maintained, managed, and backed up. The service is available to users over a network, which is usually the internet. It allows the user to store files online so that the user can access them from any location via the internet. The provider company makes them available to the user online by keeping the uploaded files on an external server. As the cloud provides many features it has some drawback too.

Security While Using a VPN
However, while the features are useful for providing basic computation and storage resources, they fail to provide the security and that many customers would like. Security is a top concern among organizations evaluating cloud service providers. While most service providers allow customers to implement their own security measures, few of them have comprehensive security tools to offer their customers.
Among these tools, one of the most important to customers and service providers alike is the ability to securely interconnect physical and virtual data centers with virtual private networks (VPNs). VPN (Virtual Private Network) technology provides a way of securing information being transmitted over the Internet, by allowing users to establish a virtual private “route” to securely enter an internal network, accessing resources, data and communication via an insecure network such as the Internet.
How It Works
VPN (Virtual Private Network) is a generic term used to describe a communication network that uses any combination of technologies to secure a connection tunneled through an otherwise unsecured or distrusted network. Instead of using a dedicated connection, such as a leased line, a virtual connection is made between geographically dispersed users and networks over a shared or public network, like the Internet. Data is transmitted as if it were passing through private connections. VPN transmits data by means of tunneling. Before a packet is transmitted, it is encapsulated in a new packet, with a new header. This header provides routing information so that it can traverse a shared or public network, before it reaches its tunnel endpoint. This logical path that the encapsulated packets travel through is called a tunnel. When each packet reaches the tunnel endpoint, it is De capsulated and forwarded to its final destination. Both tunnel endpoints need to support the same tunneling protocol.
Over the last few years, the hybrid/public cloud computing model has gained increased acceptance in the enterprise business community as a means to provide quick, low-cost, and scalable services. The availability of many other variant services from the cloud offers flexible choices that meet varying business needs. The key driver for cloud adoption is the ability to provide “always-on access to applications” with increased application availability at a large scale, in a quick and secure fashion, and at an overall reduced cost.
VPN and Business
Enterprise IT owners’ worldwide use VPN to meet the connectivity needs of their businesses with security, performance and availability. As these enterprise owners look to deploy cloud-based solutions more extensively, they expect a similar experience; in essence, they are looking for enterprise-grade network services when connecting to the public cloud. However, many businesses connect to public cloud providers over the Internet.
Recent industry research indicates that security, reliability, low latency, and predictable performance are priorities for enterprise business owners as they build private clouds or deploy a hybrid cloud model. Services that extend the performance metrics of their VPN, offering to provide connectivity to the hybrid/public cloud infrastructure, are desperately needed by performance-conscious enterprise organizations. Consequently, service providers are looking at ways to define and deliver managed services in this new agile and open, multivendor services driven-market.
On the technology side there are several innovative solutions surfacing on the market to meet the virtualized, on-demand availability and growth needs of the enterprise. As the demand grows for open and agile solutions on a large scale, virtualizing the network, storage and computing resources in an integrated fashion have become a critical need.
Today’s network architecture experts are stepping up to integrate increased virtualization in an effort to improve the time to market for service delivery in a dynamic and automated environment. Today, service providers have the opportunity to insert themselves into the cloud services chain and evolve their network architecture to support the agility and distributed scalability of cost conscious enterprise business customers.
In controlling scheduling, data and resource allocation are the problems faced while providing security to the cloud environment. Hence to provide control to the seeker for scheduling and resource allocation and to provide ownership to the data owner, the cloud computing security need to deploy several security authorities. This technique is known as an authority coordinator. It is mainly required in securing the data in cloud computing environment.
Security Concerns
Data Security:
The logical and physical data control can be provided in this concern. Phishing, virtualization, denial of service leakage of data and loss of encryption keys are also concerned.
Traditional security
This security concern includes network and computer attacks on cloud environment.
Privacy and Legal Issues
This concern is necessary while dealing with globally distributed networks.
Third party data control
This concern is very transparent, difficult and well understandable because third party in cloud environment who holds all the applications and the data.
Availability
This involves critical applications and data that are available on cloud. It can also be used to reallocate to other provider, long-term viability of the cloud.
