Cloud computing is undoubtedly popular among technology geeks who keep looking for new progress on the road. Indeed, their concern for the safety throughout the use of Cloud is also obvious. Therefore, in order to satisfy their need for reliable cloud utilization, VPN joins the League. Both these tools are completely different. Cloud computing may move the servers into the cloud and VPN will help you in taking the advantage of a safe virtual network over an Internet connection that is public.
What is Cloud VPN?
VPN for CLOUD represents the connection of VPN and The Cloud which are two of the most advanced Internet features. One is about improving the performance and other is about providing a safe environment. This smart combination gives much better performance.
In a specific case, let us assume that a company wants to increase its server capacity for a certain period of time, and thus wants to add a server from the cloud. Virtual private network plays an important role in starting a secure LAN connection between the enterprise database and the cloud. It is this tunnel, which establishes a site to site VPN connection between the two endpoints using public IP addresses. Achieving such a combination is possible with the help of service providers that offer virtual private LAN service (VPLS). Cloud computing and enterprise services are best for availing this kind of network services.
Benefit of Cloud VPN Service
Using a cloud vpn provides four key IT security advantages:
Virtual private networks are used when computers on two separate networks need to communicate securely over a public network. For example, a company can create a secure tunnel that connects the private networks of two offices over the Internet, eliminating the need for expensive leased lines. Or the employer may need his employees to use a VPN connection while accessing company resources from a public place or while on the move.
1.Avoid Packet Duplication:
Even if you send encrypted information – such as a password – over the Internet, an attacker can still have access to this information and have it saved. To avoid this, VPN uses a variety of tactics. It assigns a sequence number and timestamp to each and every packet. This helps in avoiding duplicate packets to be re-transmitted over the cloud.
2. Prevent data modifications:
Another notorious tactic that hackers use is that they change the packet contents. Using hashing, encryption and a variety of several other techniques, the integrity of the message over the cloud is maintained and controlled.
3. Verifies the sender:
Each data source can be authenticated if its transmitted over a secure VPN channel. This helps in ensuring that there are no false packets sent on your behalf.
4. Maintains confidentiality:
Communicating via a secure VPN ensures that all messages are encrypted. This limits eavesdroppers as they will not be able to listen to what you or your employees are sending over the Internet. This extra layer of protection is especially important when communicating over unreliable networks such as those found in hotels and cafes.
For anyone doing business in the cloud, and accessing business applications from remote locations, a cloud VPN is a must. There is no better way to preserve secrecy or prevent intrusion into your online interactions.
