The term ‘Proxy’ is a contraction that comes from the middle English word
procuracy, a legal term meaning to act on behalf of another. You may have
heard of a proxy vote. Where you submit your choice and someone else votes
the ballot on your behalf.
In networking and web traffic, a proxy is a device or server that acts on
behalf of other devices. It sits between two entities and performs a service.
Proxies are hardware or software solutions that sit between the client and
the server and does something to requests and sometimes responses.
The first kind of proxy we’ll discuss is a half proxy. With a Half-Proxy, a
client will connect to the proxy and the proxy will establish the session
with the servers. The proxy will then respond back to the client with the
information. After that initial connection is set up, the rest of the traffic

The mad dash to connect virtually every noun to the internet or the Internet
of Things is creating a massive M2M network for all the devices, systems,
sensors and actuators to connect & communicate on the Internet.
With that, they need a communications protocol to understand each other. One
of those is Message Queue Telemetry Transport (MQTT). MQTT is a “subscribe
and publish” messaging protocol designed for lightweight machine-to-machine
(or IoT) communications.
In this episode of Lightboard Lessons, I light up how MQTT works.

What Is the Domain Name System (DNS)?
Imagine how difficult it would be to use the Internet if you had to remember
dozens of number combinations to do anything. The Domain Name System (DNS)
was created in 1983 to enable humans to easily identify all the computers,
services, and resources connected to the Internet by name—instead of by
Internet Protocol (IP) address, an increasingly difficult-to-memorize string
of information. Think of all the website domain names you know off the top of
your head and how hard it would be to memorize specific IP addresses for all
those domain nam... (more)

Update servers while continuing to process application traffic.
Recently we’ve been showing how to deploy BIG-IP (and F5 WAF) in various
clouds like Azure and AWS.
Today, we’ll take a look at how to update an AWS auto-scaled BIG-IP VE web
application firewall (WAF) that was initially created by using this F5 github
template. This solution implements auto-scaling of BIG-IP Virtual Edition
(VE) Web Application Firewall (WAF) systems in Amazon Web Services. The
BIG-IP VEs have the Local Traffic Manager (LTM) and Application Security
Manager (ASM) modules enabled to provide advanced ... (more)
