014 years, Google Index data volume of about 200TB (1T equals to a GB). Moreover, it is estimated that Google's 200TB accounts for only 0.004% of the entire Internet. Basically, the Internet is a place with unlimited information.
So, in an effort to reduce search and improve development, Morpheus Data publishes a huge list of free resources that are helpful to devops engineers and system administrators , or someone who really wants to build something useful outside the Internet.
If you find this list useful, you are welcome to share it with us.
