About the Course

Cloud computing systems today, whether open-source or used inside companies, are built using a common set of core techniques, algorithms, and design philosophies – all centered around distributed systems. Learn about such fundamental distributed computing "concepts" for cloud computing. Some of these concepts include: clouds, MapReduce, key-value/NoSQL stores, classical distributed algorithms, widely-used distributed algorithms, scalability, trending areas, and much, much more! Know how these systems work from the inside out. Get your hands dirty using these concepts with provided homework exercises. In the programming assignments, implement some of these concepts in template code (programs) provided in the C++ programming language. Prior experience with C++ is required. The course also features interviews with leading researchers and managers, from both industry and academia....

Very useful course. It built my Cloud Computing basis from scratch. Fisrt course gives me the enthusiasm to start the later ones. A good place for studying and sharing with course mates. Thank you!

I would not recommend this course. Weekly tests are too long and the programming assignment is absurdly difficult.

The course is very interesting as an introduction to Cloud Computing. You learn many concepts related to distributed systems and several protocols on them. Theory and practice are balanced, including practical exercises in the weekly tests and a programming assignment.

However, the weekly tests are very hard from week 3 on, having to spend 1-2 hours to finish them as you need paper to do some drawings. The programming assignment is very difficult, unfair and purposeless. The template is written in C++ and it is not very helpful. You spend 80% dealing with C++ issues rather than learning the protocol concepts. I think you get the whole idea of the protocols without having to spend more than 20 hours creating such a complicated program. Many people didn't complete the course just for not being able to finish the program.

Thought it was a waste of my time- made it halfway and quit, Primarily because what is covered in the lectures doesnt give you enough answers to pass the homework quiz - you can ace the knowledge checks in the lecture and fail the homework miserably.

Also, the instructor to be a bit unfocused - he only read the slides. The homework it was maddening. Much of what was in the homework was never covered in the course. For example in Homework 3 there are 4 or 5 questions about Ternary trees in Gnutella which is NEVER mentioned in the lectures.

I thought this might be a useful course but it turned out to be highly theoretical focused on the details about things like detailed approaches to Peer to Peer (which might be useful in context but seemed to be better served in a Cloud Computing Theory class.

This course was a time wasting struggle. The instructor is not available for any kind of help. The course lectures need to be in sync with what is being asked in the weekly quiz. Instructor really needs to be available for help.

A thorough conceptual overview of cloud computing, distributed systems and peer-to-peer systems and the way they function in failure-ridden circumstances. The course gives a holistic view of the various factors and considerations that go into the design and operation of large scale distributed systems involving thousand of discrete computers over an expansive and unreliable network. The course requires good knowledge of C++ in order to complete the programming assignment. The quizzes and homework are mildly challenging and require patience to carefully work out the problems but the programming assignment is the one that will take the largest time commitment and it helps to get started early with it.

The course is very well laid out. Prof. Gupta has a very clear voice and is easy to follow. The tests at the end of each chapter are non trivial and really ensure you understood the concepts thoroughly. The course is fairly old (2012?), for a rapidly developing field like cloud computing, I imagine several portions of the course are probably out of date. I suggest the relevant portions of the course be updated periodically. Even if the course is not entirely revised, at a minimum add an extra section highlighting the new changes.

The course teaches a lot of core concepts of distributed systems (clouds included). The content is well delivered and the homework reflects the material very well. The homework is appropriately tough.

There is an optional programming assignment for setting up a distributed network of nodes with failure detection. I learned a lot about gossip based information spreading while doing the exercise. That said, the assignment is not clearly explained and it is hard to get started.

Overall I did enjoy the course and learned a great deal.

The presentations are very good, some of the best I've seen in a video lecture series. With this in mind, there were lectures where I felt a bit more explanation would have helped me. For those I found additional external resources.

I enjoyed the programming assignment; but, the assignment uses too many different ways of storing the address. One consistent way should be chosen between the Node / Emulation Layer / Member, preferably a non-char packed approach (unless the address is always handled as a plain text string).

Great course overall, personally I've especially liked the programming assignment! It's not production quality code for sure, but it was fun to implement, although if you don't have C++ experience, then it can be difficult.

The homework quizzes were hard, especially in the final weeks, and required retrying multiple times at some points — but it's definitely worth it, since the difficulty helps with gaining better understanding.

The material is covered in depth and clearly, the content is very current while still covering the historic origins and the development of the current state fo the art. It comes with evaluations that are not aimed towards memorization, but rather towards understanding the subject. As a cherry on top, they allow you to take a verified certificate towards credit on the Masters degree.

Cloud computing course provides an overview of the concepts of distributed processing. The algorithms behind real world distributed applications are well explained. The video lectures and quiz questions on various distributed protocols provide insights into the working of these systems. Highly recommended. Thanks Prof. Indranil Gupta and the Coursera community!!

The course was quite enjoyable, I love the assignment part I wish it was in Java. Struggled with the C++ memory manipulation part of the algorithm which was nothing to do with the actual implementation, having not coded in C++ over a decade was reason for the struggle. Overall all quizzes and final assignment was both challenging and enjoyable.

Perfect! The professor explain concept clearly and easy to understand. The course cover the concept and the real product in industry, so you will not be boring. The programming assignment is interesting, and it's really a challenge for me as my poor C++ :( . It take me almost 12 hours to finish the programming assignment.

Excellent course. I'm looking forward to continuing in this specialization.

Do read the description of the course carefully before starting. It is not for beginners. However, if you can program in C or C++ and have a solid computer science background (Bachelor's degree or equivalent), this course will be quite easy.

Was looking for MOOC to start learning about Distributed Systems/Cloud Computing. After completing this course and going through the readings suggested, feel its a good start and i got an insight into the foundation concepts/primitives that make distributed systems work. Highly recommend this course!

Everything was really well explained, quizzes are hard as they need to be, but not impossible and the instructor has a really good personality.

The only "bad" thing was the programming assigment. It was really hard (but again, possible) and the specifications were poor.

In general, a five star course.

a very good course for cloud study. the content is colorful , a lot of examples to support deep understanding of the concepts. The biggest drawback is that maybe there can be some small programming assignment after each week's course. And the standard answers of the Week5 quizz have some bugs.

The course is worthwhile. The instructor explained the concept clearly in engaging way that I rarely found on Coursera. The most I liked is the design of assignments. As well as, it has some interviews of academics and professionals which shapes your thoughts very well.

It's a well organized course which makes me rebuilt my knowledge base. I've read parts of the concepts during my past work, but most of them confused me. This course gives me a "aha" moments to pick all the fracture parts together. I'll follow the next courses.

Very well taught, easy to understand. The questions in the exams have been very thoughtfully selected, one must pay attention to the content and understand the concept. Going to remember the concepts for long time after watching & listing the tutorials.

Interesting and challenging programming assignment. I like to topics this course goes through: membership protocol, snapshot, CAP, and Paxos. I would highly recommend people who are interested in distributed system take this course.

An excellent course for a beginner who wants to explore the world of cloud computing. The instructor explained all the concepts very well. Just the programming assignment was a bit difficult as no insights were provided to it.

I am giving a 5 starts because I really enjoyed the course and I learned a lot. but to be honest I almost gave up. The programming assignment is a little bit frustrating since there is really not help and not much guidance.

Amazing, very rich content, it allows you to go deep in understanding distributed systems. May be a hard course if you are just looking to understand cloud computing superficially, and much more if you don't know C++.
