What is load balancing

 

 

Load balancing is a technique used to distribute workloads uniformly across servers or other compute resources to optimize network efficiency, reliability and capacity.

 

Load balancing is performed by an appliance -- either physical or virtual -- that identifies in real time which server in a pool can best meet a given client request, while ensuring heavy network traffic doesn't unduly overwhelm a single server.

In addition to maximizing network capacity and performance, load balancing provides failover. If one server fails, a load balancer immediately redirects its workloads to a backup server, thus mitigating the impact on end users.

Load balancing is usually categorized as supporting either Layer 4 or Layer 7. Layer 4 load balancers distribute traffic based on transport data, such as IP addresses and Transmission Control Protocol (TCP) port numbers. Layer 7 load-balancing devices make routing decisions based on application-level characteristics that include HTTP header information and the actual contents of the message, such as URLs and cookies.

The Pi Zero ENC28J60 solves this problem, it is a simple to use network adapter module designed for the Raspberry Pi Zero/Zero W.  IIC I2C Logic Level Converter Bi-Directional Module 5V to 3.3V For Arduino Only $2.00! Many sensors provide a voltage level which informs the Raspberry Pi or a microcontroller such as the Arduino about their change of state. Now recall that the Raspberry Pi's GPIO pins are designed for use with 3.3V inputs and outputs. Some sensors operate on 5V, so feeding its output directly to the Raspberry Pi's GPIO pins runs the risk of damaging either the sensor or the Raspberry Pi. Imagine not knowing about this and wiring it up erroneously, you'd hope to see spectacular blow-ups and magic smoke! However, we usually see nothing, no fun at all - it just eventually stops working. Which can be frustrating when it comes to troubleshooting. This I2C bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. Imagine having the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side. Handy! Micro SD Card PCB Extender Only $9.00!

Windscribe for your online security - Review.

I have been trialing Windscribe  for a while now and have found it to be a very stable and useful platform,  I have been using it in Crome browser, to secure the browser, but it works equally well on the desktop.

To learn more read on...


What is Windscribe?

Windscribe is a set of tools that work together to block ad trackers and web beacons, restore access to blocked content and help you safeguard your privacy online.
 
What are these tools?

There are 2 components: desktop VPN application, and browser extension. You can use them on their own, but for much greater protection, you should use both. It's silly not to, since it doesn't cost extra.

How much does Windscribe cost?

If you are a light user, you can use Windscribe for free. You get up to 10GB of data per month, and you can use all of the tools we offer. If you need more data, for just $9/month you get unlimited usage. You probably spend 10x that on coffee alone!
(Tip: Tweet out your Windscribe link and get an extra 5GB per month FREE)

What does the desktop application do?

The desktop application is a Virtual Private Network (VPN) client. It creates an encrypted tunnel from your computer to our servers, and all your activity is sent through the tunnel. (Perfect if the corporate firewalls and proxies block your fav Netflix channel)

What does the browser extension do?

The browser extension provides a "Lite" VPN client, which does the same thing as the desktop one, but only in your browser. Any other applications you may be using on your computer will utilize your ISP provided IP address. This is the one I have been trialing and it works great!


Now for the Nerdy stuff..... :-)

Encryption parameters 

Windscribe uses AES-256 cipher with SHA512 auth and a 4096-bit RSA key. It supports perfect forward secrecy.

connection modes

Connection modes allow for connecting to Windscribe servers using different ports and protocols. This exists to make sure that if a certain port is blocked, or your network operator is performing deep packet inspection in order to track down VPN usage, you can still connect. The default is "Automatic" which will pick the best mode for you. You can switch it to manual mode if you wish.

Modes available

•     IKEv2 - Default connection mode, usually the fastest, but can be easily blocked.

•     UDP - This mode uses OpenVPN protocol. UDP is usually the fastest protocol to run OpenVPN on, but can also be blocked quite easily.

•     TCP - Use this if UDP fails to connect. Much more resilient to bad network conditions, but could be slower.

•     Stealth - Encapsulates OpenVPN in a TLS tunnel via Stunnel. Only use this if all other methods fail. May be handy in China.

•     Wstunnel - Encapsulates OpenVPN in a WebSocket. Only use this if all other methods fail. May also be handy in China.

 All in all I highly recommend Windscribe as a service, they have great support and many more tools than listed here to keep you safe from the baddies online.
