Even though this week was brief, it was plentiful in objectives to accomplish. In class we started learning about data centers work and how virtualization plays a key role in them. At the end of the week we added to our LAMP stack, we started an instance and continued following each step. Additionally, we discussed RAID and its use cases in the industry that RAID would be used for. Before I came to the lecture, I thought of RAID as just arrays of supersized external hard drives, I know now they are a tool that protects data. Below I included a short Youtube video that simplifies the concept into the essentials.
