Hello, world! Welcome to the Racklet blog! If you like cloud computing, security, embedded development and innovative design, this is the place for you. The Racklet community and developers are designing a tabletop datacenter for education, research, tinkering and what ever use you may come up with. Keen to hear more and to contribute? Read on! A Tabletop Datacenter? Racklet is a cluster computer system powered by single board computers. A cluster computer is essentially just many individual computers connected to the same network to collaborate on programs to run. These computers are typically highly powerful servers in a datacenter, but they can techincally be anything -- we're using credit-card-sized single board computers like the Raspberry Pi. In a cloud computing datacenter, the programs that are run on cluster computer systems are the websites and databases we rely on every day, such as search engines, video streaming services, cloud storage and wiki-pages. Racklet aims to be fit for these tasks as well, just on a scale that fits on your desk. With this scale obviously comes lower performance, but crucially an affodable price and good accessibility as well. Learning from the Hyperscalers The largest companies in the world operating cloud services, such as Google, Amazon, Facebook and Microsoft, are called the hyperscalers of the cloud industry. These companies have a lot of money to spend on cloud research and development, and one of their biggest challenges is security. Google just committed to investing $10 billion to improving the state of cybersecurity over the next five years.
