Instance Cloud Computing offers the most advanced networking features available today. From simple to use direct-IP networking to more advanced virtual networking with load balancing and firewall features you use to can create a network infrastructure suited to your needs, not to those of the provider. You can also create a combination of both types of network offerings as well as traditional dedicated services for a hybrid environment, leveraging the benefits of each technology. Consider the types of networks that are offered below:
This is the preferred network configuration within the instance.com offerings. Choosing this network configuration gives you scalability, security and lower costs. Through the use of the virtual router and private RFC 1918 IP space (private IP’s) you can create high performance, secure environments from 1 to any number of servers.
By using a single public IP address you can direct traffic to the required server(s) by mapping the proper external port to the internal port hosting the services. If you have two servers hosting a service on the same port, you can create a port-forward mapping two distinct external ports, to the port hosting the service on the servers behind the virtual router. Sometimes you just can’t change the port a service runs on which is typical of public web servers where you can’t provide a unique URL such as http://my.developement.site:8080 or for mail servers, name servers and any other service where the public client expects a standard port. Given this requirement, the instance.com offerings allows you to acquire additional IP addresses as needed to meet these requirements.
Direct networking is a more simple and traditional networking configuration. With direct networking your instances are assigned a public IP address that is bound directly to the interface on the server. Instances deployed with direct networking are not able to use the firewall/port-forward option, nor can they participate in the built-in load balancing offering. By default they also do not have access to the internal virtual LAN that may be available should you have additional instances configured with the virtual networking option. Example advanced network configurations presented later on will show you how this is possible with the instance.com cloud offering.
The instance.com product is flexible and allows you to create complex and advanced network deployments for environments which have special requirements. These environments can be a mixture of both direct and virtual network configurations and can be combined with traditional hosting services such as dedicated servers and server/network collocation. Below are example network configurations that can be configured on the instance.com cloud offering and network.
You can combine the benefits of direct networking and virtual networking to build custom tailored networks. This is useful in situations where you have specific server(s) that need to be completely accessible to the Internet without being behind a virtual router or firewall, but also need access to the private virtual network where the rest of your instances reside.
Instance.com supports the integration of the 1-800-HOSTING dedicated server network. By leveraging the power and benefits of both technologies you can create high performing and secure application environments which give you both the power and security of a dedicated server environment with the scalability and reliability of the instance.com virtual servers.
The example below is typical of common requirements for both types of services. The example shows how you can build scalable web servers that can be load balanced for performance and scalability along with the benefit of being able to quickly turn-up additional web server resources on demand. These instances have an additional network added to them that allows access to the 1-800-HOSTING dedicated server network where the customer may have database and/or additional servers already deployed behind their hardware firewall.
