Collaborative Intelligence: Humans and AI Are Joining Forces

Artificial intelligence is becoming good at many “human” jobs—diagnosing disease, translating languages, providing customer service—and it’s improving fast. This is raising reasonable fears that AI will ultimately replace human workers throughout the economy. But that’s not the inevitable, or even most likely, outcome. Never before have digital tools been so responsive to us, nor we to our tools. While AI will radically alter how work gets done and who does it, the technology’s larger impact will be in complementing and augmenting human capabilities, not replacing them.

AWS Lightsail is awesome

AWS have recently introduced a new service called Lightsail which I think is really great to use as a replacement for my home-server.

I use my home server(s) extensively for my work as a big data developer. My home setup consists of Ubuntu with LAMP stack on it. Which is perfect to host some presentations, websites, share files and the most important is my stepping stone when I need to access free Internet bypassing corporate firewalls.  My home-server is running day and night every day consuming some power and requires regular updates or maintenance from time to time.

Summary of pros and cons of Lightsail vs home-server

Lightsail Home-server
Power usage included have to calculate
Availability 99,9999% ~80%
Maintenance included manual
Scalability included NA
Backup snapshots manual

In contrast AWS Lightsail is living in a AWS cloud and is always online for as little as 3.50 USD a month.  The service is available as Linux or Windows and ready to be configured as application where you can chose from WordPress, LAMP stack, Node.js, GitLab and few more.

The host operating system can be selected from very small 512MB RAM, 1GB CPU, 20GB disk and 1T data transfer up to 8CPUs, 32GB RAM and 640GB disk space.

And then the best thing is a price starting at 3,50 USD a month. Which is bargain compared to running costs of my homeserver considering initial hardware cost, power used, time spend on updates and maintenance and also very important I’m not depending anymore of my home internet connection which sometimes goes down or my semi-static DNS address which can change from time to time.

Power consumption consideration

[number of  hours’ use] x [number of days’ use] x ([capacity of appliance expressed in watt] / 1,000) = number of kWh

Given that I have two desktop computers running 24/7 whole year consuming on average  100 Watts then only electricity costs are around 440 EUR a year.  The cheapest Lightsail option cost 3,50 * 12 = 42 EUR per year. Okay it’s not fair to compare home desktop with 8 TB storage and 32GB RAM to a Lightsail instance comparable to Raspberry Pi. For the record Raspberry Pi running whole year will cost only 5 EUR. But if I only turn the desktops ON when needed which is (at the moment mostly working from office)  about 3 hours a day [(3*356*(100/1000))*0.24 = 25,6 EUR].
