Networks of containers, each perfoming its own specialized
function, will allow teachers and students to work cooperatively,
creating distributed data networks and services.
An algorithm is a well-defined procedure that allows a computer to solve a
problem
By putting powerful applications into the hands of students we create new
possibilities for manipulation, visualization and creativity.
Students
are now able to not only create text, music and art, but also to
edit and create new tools to create text, music and art.
Dockerfile is a new type of file which creates and provisions
service such as amazon web service (I'm not sure that I have understood
this correctly)
Decentralized and distributed computing allowed MMC companies like Coursera
and EdX to serve thousands of students at a time. Today, this
capacity is available to everyone.
Sophisticated computing containers are created using programmes
like Docker, which is a type of container engine.
It allows
us to download and run images which contain a preconfigured lightweight
OS, set of libraries, and application specific packages.
When we
run an image, the process spawned by the Docker engine is called a
container.
"the cloud" is just shorthand for someone else's computer. The conceptual
challenge is that it doesn't matter whose computer it is, that it could
change at any time.
The Cloud may be decentralised and distributed,
but not necessarily (I am not sure whether this point is correct as
it is not explained in the synopsis and a search doesn't give me a clear
answer)
The cloud can be thought of as a commodity like water
We should begin to think of storage and computing as commodities rather
than as features of a type of device that sits on your desk.
Learning a concept as simple as "load-balancing"- a mechanism where
requests to a single web-page are sent to different computers to spread
out the load - is a doorway to being able to imagine and understand deep
and complex service networks.
We should begin to think of storage as a commodity
The cloud can be thought of as a commodity like electricity
cloud-based computing begins with the concept of server
virtualization
cloud-based computing begins with applications such as VMWare or
Parallels
Sophisticated computer containers are run using services like
amazon web services or Digital Ocean
These services are created and
provisioned through a maze of new types of file with names like
'Dockerfile' or 'Vagrantfile' or Yaml.
As a result, we are now able
to see entire computing environments as pieces of context we can
exchange back and forth with each other.
edX is a MOOC provider
coursera is a MOOC provider
yaml is a new type of file which creates and provisions service
such as amazon web service (I'm not sure that I have understood this
correctly)
vagrantfile is a new type of file which creates and provisions
service such as amazon web service (I'm not sure that I have understood
this correctly)
Jupyter Notebook is essentially a text document - a notebook -
with live functioning computer code inside it that you can modify and
run again as often as desired.
Jupyter Notebook can run in Docker (I'm not sure whether that
is correct)
It is a new file type like yaml, vagrantfile, dockerfile
These new resources allow us to redefine what we mean by concepts such as
'textbooks' and even 'learning objects'.
By putting powerful
applications into the hands of students we create new possibilities
for manipulation, visualization and creativity
Students will be able to directly experience the relation between algorithm
and outcome, or between mathematics and music as the case may be.
Computing containers enable
cloud-based computing.
A
container is an entire
computing environment which we can see as
pieces of context we can exchange back and forth with each other
(again
I'm not sure that I have understood this correctly)
Containers with entire websites are as easy to download and deploy on
your as clicking a link or opening a PowerPoint.
