Whitelisting vs Blacklisting, preventing or reacting

There are different security methods out there, but when it comes to data filtering, there are two widely-used ones. You can use either whitelist (allow, give a permit) or blacklist (block, put in the list of forbidden). There is a big debate in the IT community which is better. Whitelisting vs Blacklisting.

DNS load balancing vs. Hardware load balancing

Why do we need load balancing?

With the massive increase of the internet traffic each year, it is getting harder to provide a sustainable service for all the millions of clients without having some downtime. For this purpose, you need to apply a model of load balancing, that will reduce the load caused by the countless users trying to reach your website or use your application.

Another reason why you need to use load balancing is the rising number of DDoS attacks. To evade them you will need to spread the traffic to as many as possible servers that you have. That way, their combined efforts can resist the wave of high traffic.load balancing
