SoftLayer is the largest provider of dedicated hosting in the world. They combine "bare metal" servers and Infr
But what exactly is a bare metal server or a virtual server, and how can you use them? Here, then, are 5 things to know about SoftLayer.
1. SoftLayer's network is larger and faster than yours
Any company offering cloud capabilities needs a fair amount of bandwidth. A couple of servers in a single data center isn't going to cut it. SoftLayer's network and capacity are impressive by anyones standards. 13 data centers house around 200,000 servers. Those data centers are located around the world (the US, Singapore, the UK, and the Netherlands) and are each connected to each other over dedicated 20Gbps fiber links over a private network. And those data centers host servers for 21,000 customers.
2. Virtual servers for convenience, bare metal for performance
A virtual server is a virtual machine running on a hypervisor (an operating system), hosted on a physical server. That same physical server could host multiple virtual servers. So one server running a Linux operating system could host one virtual server running Windows, and other running Red Hat. SoftLayer offers virtual servers that can be set up in minutes and scaled as needed. But virtual servers also come with a performance penalty. The virtual machine abstracts the physical resources of the server, such as its RAM and CPU, creating an overhead that makes it inappropriate for some high performance workloads. That's where bare metal (a non-virtualized dedicated server) is a better option. SoftLayer can create bare metal servers for you, where you design the hardware to specific requirements, and still manage the server from the cloud. No virtualization performance penalty, but the same advantages of centralized management in the cloud.
3. You can customize everything
There are plenty of ways you might want to customize your SoftLayer infrastructure. Pick the right netw
