Yes it is, and can very well be self taught, I think.
Are there any specific steps to consider?
In the last several years, the National Security Agency’s global eavesdropping programme has become the subject of intense public debate, drawing attention to how much our personal information is shared in this system.
But as our digital lives become increasingly connected, how can we prevent data breaches or defend against surveillance? We don’t know how to secure our data – or how to keep it safe from hackers, if those hackers are out there.
Enter the world of cloud computing: the ability to store data on remote servers that are shared by more than one computer. It’s not exactly a new concept, but there’s a reason why its popularity has increased.
In a blog post, the former chairman of the NSA said that the agency is looking to increase data security by building “cloud” data centres. In addition to the NSA’s own facilities, this will involve the installation of servers controlled by third parties. The purpose is twofold: to boost overall data security and to make the US government more competitive globally.
“You never know when somebody wants to make a change, and you have to react to it in a timely manner,” NSA’s retired director, General Keith Alexander, told ABC News. “It might be the time of year when you’re having a data centre down here to do a [data centre] upgrade. It might be the time of year when you’re having an IT team come in. It might be the time of year when the [Department of Defense] and the [Department of Homeland Security] decide they’re gonna build a new data centre.”
There are several reasons why cloud computing is becoming a powerful alternative to centralized data centres. For one, it’s not only faster and cheaper to buy data centres, it also offers a far greater degree of flexibility.
“A lot of people talk about data centres being a bottleneck in data,” said Alex Dusil, co-founder of New York-based CloudFlare, in a phone interview with the Register. “You end up needing to manage a very large infrastructure and having to keep it current. These cloud solutions have an ability to really scale from the bottom up and offer you more granularity in terms of storage and data.”
In addition to being cheaper than data centres run by a company, Dusil argued that cloud servers require far less power than a traditional central server.
