However, if you are able it will give the benefits of both protocols. The three are often confused because they share some key characteristics and can even be used together. You can create a VPC where instances in one subnet, such as web servers, communicate with the Internet while instances in another subnet, such as application servers, communicate with databases on your corporate network.

An IPsec VPN connection between your VPC and your corporate network helps secure all communication between the application servers in the cloud and databases in your data center.

You can move corporate applications to the cloud, launch additional web servers, or add more compute capacity to your network by connecting your VPC to your corporate network. Because your VPC can be hosted behind your corporate firewall, you can seamlessly move your IT resources into the cloud without changing how your users access these applications.

In the event of a disaster in your own datacenter, you can quickly launch replacement compute capacity in AWS to ensure business continuity. When the disaster is over, you can send your mission critical data back to your datacenter and terminate the Amazon EC2 instances that you no longer need. By using Amazon VPC for disaster recovery, you can have all the benefits of a disaster recovery site at a fraction of the normal cost. You can configure this VPC by adding or removing subnets, attaching network gateways, changing the default route table and modifying the network ACLs.

Get started with Amazon VPC. Benefits Secure Amazon VPC provides advanced security features, such as security groups and network access control lists, to enable inbound and outbound filtering at the instance level and subnet level.

Connect directly to the Internet public subnets — You can launch instances into a publicly accessible subnet where they can send and receive traffic from the Internet.

Connect to the Internet using Network Address Translation private subnets — Private subnets can be used for instances that you do not want to be directly addressable from the Internet. Instances in a private subnet can access the Internet without exposing their private IP address by routing their traffic through a Network Address Translation NAT gateway in a public subnet.

Connect securely to your corporate datacenter— All traffic to and from instances in your VPC can be routed to your corporate datacenter over an industry standard, encrypted IPsec hardware VPN connection. Privately connect your internal services across different accounts and VPCs within your own organizations, significantly simplifying your internal network architecture. Use cases Host a simple, public-facing website You can host a basic web application, such as a blog or simple website in a VPC, and gain the additional layers of privacy and security afforded by Amazon VPC.

VPS hosting uses the principles of shared hosting to reduce the cost of operation by placing several accounts on the same server. Each account is placed on a virtual partition of the server to give it the independence of a dedicated server, allowing businesses more control over their server environment in addition to a host of other benefits. VPS hosting is ideal for small to medium businesses who are in need of fast performance and security, but are not in a position to pay for the additional cost.

It offers the ability to share information between distances much like a desktop sharing program. Much like a VPS hosting plan offers small and medium businesses a bridge between the limits of shared hosting and the cost of dedicated hosting, a VPN offers the security of a private Intranet, without the high costs associated with them.

It is truly a more cost effective option when compared to investing in the server equipment and the expertise to develop and setup the network. Unless you are sharing private information and data across the Internet with other offices and people who work with you, you probably will not need a private network.

Most businesses can encrypt information to protect it from hackers and other prying eyes, without the use of a VPN.
