Join Mike Meyers for an in-depth discussion in this video IaaS (infrastructure as a service), part of CompTIA A+ Exam Prep (220-902) Part 4: Virtualization, Printers and Troubleshooting.
- Virtualization has been around with us now for a while,…but it continues to amaze me in the way that it affects…the entire IT industry.…It wasn't that long ago that we began to see…physical servers being replaced by virtual machines…at individual locations, and we still see tons of that.…But what starts to happen is,…when you take all of this hardware and virtualize it,…companies that have a lot of money behind them…can start to build up really big farms of virtual machines…and can do all kinds of really cool things that allow us…to pretty much just take all this away.…
We don't even, in many cases, need to set up our own…virtual machines.…We can let other people take care of that for us.…This manifests in a lot of different ways, but the first one…I wanna talk about is something called…Infrastructure as a Service, or IAAS.…Infrastructure as a service simply means…that somebody far away will set us up…a virtual infrastructure to do bazillions of things…that would normally cost us a lot of money as we brought in…
Here CompTIA expert Mike Meyers prepares you to answer questions about slightly more advanced topics: "super tech" skills like managing files via the command-line interface, creating virtual machines, connecting to the Internet, installing printers, and troubleshooting startup and application issues. Each lesson prepares you for a related topic on the 90-question A+ exam.
