Powerful Denial of Service attacks are becoming increasingly common. A
Distributed Denial of Service attack is when the attacker uses multiple
machines to flood the resources of the target to overwhelm it and deny the
legitimate users access to the service. The DDoS attack on Dyn in October
2016 was one of most powerful attacks in history. Many DDoS attacks can be
thwarted to a large extent by increasing the system’s capacity during an
attack, but that is not a solution because it still causes monetary losses.
DDoS attacks typically employ three methods:
Finding a vulnerability in the victim’s service Finding an endpoint in the
victim’s service that is computationally heavy (for example, a login system
that uses a slow hashing algorithm) but without a rate limit and abusing it
Depleting the available bandwidth of the victim’s service

With big corporations moving to the cloud for their computation needs, a new
type of resource usage model has come up recently that is called Server-less
Computing. Contrary to the meaning of the term “Server-less” in
“Server-less Computing,” it does not mean that servers are not involved.
Rather, it means that the developer is no longer required to worry about
provisioning and maintaining servers.
Server-less pushes the focus of the developer to adding features to their
applications, instead of working on the underlying infrastructure. The
concept behind this form of computati... (more)
When call centers first came about in the 1960s, they were built over PBX
systems. Private Branch Exchanges (PBX) are essentially a small-scale version
of the telephone exchange and are typically handled by one of the few
telephone network providers in the country. Fast forward to today, a call
center software provider does not need to own even the VoIP line that is
necessary to handle communication. The software can simply connect to third
party VoIP services with the help of an API and get started on their service.
The cloud has brought down the cost of operating a business and ... (more)
A number of retailers, especially small businesses, are moving away from
these expensive systems to cheaper, yet a lot more sophisticated cloud
alternatives. A typical cloud PoS system should cost retailers between $50 to
$200 a month.
Point of Sale (Pos) systems typically haven’t required an internet
connection. These devices come with a cash register, a barcode scanner and a
card reading machine that connects to the bank via a fixed line connection.
In addition to this, the higher end PoS systems come with inventory tracking
and management tools as well. All of this does not c... (more)
Pokeman Go has been a raging success. But its launch was marred by frequent
downtimes and dropped connections. In a recent chat at the Google Cloud
Platform Next Conference, Niantic CTO Phil Keslin talked about the “hair
on fire” experience where the team had to firefight and upgrade key
components on the live production system in order to handle the unexpected
surge in new users joining in.
Among the various upgrades made to the system, Niantic had to replace the
network load balancer with a much more sophisticated HTTP/S load balancing
system that could handle a larger overal... (more)
