Hello everyone,
-
I want to thank you
for, uh, joining me
-
on this, uh, journey through
Cloud Computing Concepts.
-
This is the first part
-
of the Cloud Computing
Concepts course,
-
which is a two part course.
-
Uh, this course here
-
is about the internals
of cloud computing.
-
This means that
we'll go underneath the hood
-
and look at the distributed systems concepts,
-
and the distributed algorithms,
-
and the distributed techniques,
-
that underlie today's
cloud computing technologies.
-
This course is not about
how to write cloud systems
-
or cloud applications.
-
There is a separate course,
-
uh, that's coming up,
called Cloud Applications.
-
Uh, and, uh, this course
is not about networking either,
-
in the cloud.
-
There's a separate course
-
called Cloud Networking
that's coming up,
-
uh, that's about networking inside the Cloud.
-
Uh, both, uh, w-well all
of these courses,
-
the Cloud Computing
Concepts course, this course,
-
both parts, as well as,
the Cloud Applications course
-
and the Cloud Networking course
-
are part
of a Cloud Specialization,
-
which is being offered,
uh, to students.
-
What we'll discuss in this
cloud computing concepts course,
-
uh, both part one
and part two is, uh,
-
three things.
-
Uh, concepts
-
that underlie today's
cloud computing systems,
-
especially,
distributed systems concepts.
-
Uh, techniques, uh,
that are used, uh,
-
fairly widely, in a variety
-
of cloud computing
systems today.
-
And we'll also, uh,
-
while discussing concepts
and techniques, uh, look at, uh,
-
some facets and some aspects
of industry systems
-
including open source systems,
-
uh, like Hadoop and NoSQL storage systems and many others.
-
So the cloud competing
concepts course
-
is really a mix
of distributed systems, uhh,
-
er, with a mix
of distributed algorithms.
-
And both of these combined
as applied, uh,
-
to cloud computing systems
as they are today.
-
So what we'll discuss
in this first part,
-
the first five week, uh,
-
part of the Cloud Computing Concepts course.
-
Eh, first we'll have
an introduction to Clouds,
-
what they are,
-
why they are, the way they are.
-
Uh, we'll look at Mapreduce
and Key-value stores,
-
uh, two of the, uh, emerging, subareas of cloud computing.
-
Then we look at some
of the precursors,
-
previous generations
of cloud computing systems,
-
like Peer-to-peer systems
and Grids,
-
that, uh, are ancestors,
-
parents of, uh,
today's cloud computing systems.
-
Then we'll, uh,
go underneath the hood
-
and start to look at
widely used algorithms,
-
for Gossip, Membership,
Paxos for consensus,
-
uh, and also
classical algorithms, including,
-
Time and Ordering, Snapshots, and, uh, Multicast.
-
Along the way, uh,
in some weeks,
-
we'll have interviews
with leading managers
-
and researchers from industry, as well as, academia,
-
uh, and I hope these will be interesting to you, as well.
-
The, um, uh,
-
the course is structured so that you can learn as you move along,
-
uh, so there are two home works,
-
uh, spread throughout
the course,
-
uh, uh, as well as,
a programming assignment.
-
The programming assignment
is optional.
-
It involves, uh,
writing code inside an emulator.
-
In the first part of C3,
uh, course,
-
uh, you will be writing, uh,
a membership protocol
-
inside an emulator
that we will provide to you.
-
We'll provide you the template,
-
the C++ template
and you can write it.
-
Again, the programming assignment is optional.
-
The two required, uh,
portions of this course
-
are the two home works
and the one final exam.
-
Well, cloud computing is
an exciting area to be studying,
-
to be working in.
-
And, uh,
-
it is also a very dynamic
and continuously changing area.
-
And that's what, uh,
-
that's part of what
makes it exciting, as well.
-
I'm really looking forward
to working with you
-
and interacting with you
-
as this course
move al-moves along.
-
Uh, come join me as we start
our tour of the cloud computing
-
concepts landscape.

Revision 1: uploaded subtitles; revision 2: added title and description; revision 3: removed all the "uh's", fixed the punctuation, and did some minor reshuffling to lengthen captions that were unreadable because too short.
