Note Central processing units (Cpus) are designed to run various

general-purpose tasks. They provide ease of programming and can

be used for many different use cases. however, their generality leads

to performance and cost drawbacks. performing a repetitive task

on a general-purpose Cpu seems like a waste. In such scenarios

using hardware that does specific repetitive tasks in a much more

performant manner makes sense. Specialized hardware such as an

FPGA help offload these repetitive tasks from Cpus to themselves.

They can be programmed to do a specific task well, thus providing

better cost and performance.

Provisioning Systems

An operating system is usually the first piece of software deployed on a

server as a primary step in building the infrastructure. If you have deployed

an operating system on a server, you can imagine the extensive work and

steps needed to prep the server. Additionally, diagnostic mechanisms are

required to understand any errors during this server provisioning process.

If the entire end-to-end provisioning process is done manually, it becomes

time-consuming.

Several open source projects help with the automated on-demand

deployment and configuration of these servers. They provide the speed

and agility needed in any data center environment where there are

thousands of servers waiting to be provisioned quickly. Cobbler [5-5] is

one such project among many open source options. It uses network boot

for the installation process. It also has support for virtual environments as

an additional feature.
