VirtualBox is a program which lets you quickly and easily create virtual machines.
#VAGRANT EXAMPLE SOFTWARE#
If you really need a VM more powerful than the host OS, then just give the VM more resources – like if you want to play a powerful game on your Windows machine and you’re on a Mac computer with 4 CPU cores, give the VM 3 cores and 70-80% of your RAM – the VM instantly becomes powerful enough to run your game!īut, how do you “make” a virtual machine? This is where software like VirtualBox comes in. So the VM is there only for a specific purpose, and for that purpose, those resources are far more than enough. The VM being slow is not a problem because it’s not meant to be a main machine – you have the host for that, your main computer. The resources (your CPU core, etc.) are then instantly freed up. You only run the VM when you need it – when you don’t, you “power it down”, which is just like shutting down a physical computer. The answer to both is “yes” – but here’s why this isn’t a big deal. make the VM slow, because that’s kind of a weak machine?.You might wonder – if I dedicate that much of my host computer to the VM (an entire CPU core, 4GB of RAM, etc), won’t that:
#VAGRANT EXAMPLE INSTALL#
By installing stuff onto your virtual machine, you avoid having to install anything on your main machine (the one on which the VM is running), keeping the main OS clean, fast, and as close to its “brand new” state as possible for a long time. Just power up a Windows VM, and run the application inside it (like in the image above)! For example, you have an Apple computer, but you really want that one specific Windows application that Apple doesn’t have.
Thus, the VM, when infected, can simply be destroyed and re-configured back into existence, clean as a whistle, no consequences. But if you downloaded a virus inside a VM, only the VM is at risk because it has no real connection to the parent system it lives off of. Imagine accidentally downloading a virus – on your main machine, that could be catastrophic. you can mess up anything you want, and nothing breaks on your main machine.That allows you to have a “computer within a computer” (yes, even a new “monitor”, which is essentially a window inside a window – see image below): That VM then thinks it’s a computer with that many resources, and is completely unaware of its “parent” system – it thinks it’s a computer in its own right. For example, if you have a CPU with 4 cores, 12 GB of RAM and 500 GB of hard drive space, you could turn 1 core, 4 GB or RAM and 20GB or hard drive space into a VM. In definitions as simple as I can conjure them, a Virtual Machine (VM) is an isolated part of your main computer which thinks it’s a computer on its own. Let’s start with the obvious question – what is Vagrant? To explain this, we need to explain the following 3 terms first: Just in case you’d like to rush ahead and get something tangible up and running before getting into theory, here’s the link to that tutorial. It’s recommended you absorb the theory behind it before you do that, though. The post will be mainly theory, but in the end we’ll link to a quick 5-minute tutorial designed to get you up and running with Vagrant in almost no time. By following the advice within, you’ll be doing not only yourself one hell of a favor, but you’ll be benefitting countless other developers in the future as well. Please take the time to read through the entire article – I realize it’s a wall of text, but it’s an important wall of text.
Note that this topic (among other best practices) is covered in much more depth in SitePoint’s Jump Start PHP Environment Book. We’ll be re-introducing Vagrant powered development. In this post, you’ll learn about the very first thing you should do before starting to work with PHP (or any other language, for that matter). I’d like to change that by first talking about the basics of environment configuration. And, it’s true, we don’t have many truly newbie friendly ones.
I often get asked to recommend beginner resources for people new to PHP.
