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!
Great course, I would recommend to everyone who wants to understand the basics of cloud computing. The course material is excellent, the instructor Indy is phenomenal and the exams are marvelous.

I found the concepts taught in this course interesting, but the lectures were far too fast paced (it takes twice the time to get through them if you actually want to get notes down as you will need to pause continuously). I also thought that the programming assignment was far, far too advanced seeing many people who take this course may not be familiar with C++ or programming in general. Even with my background being computer engineering, I found it challenging and spent much more time on it than the time suggested by the syllabus. Lastly, the homework was a major step up from lectures seeing there were minimal examples given in the lectures. Overall, the assessment was so ordinary that I would probably recommend not paying for this course. I kind of wish I could still get my money back.
If you want to do this course properly, double the time it tells you it will take for each part of it. You'll need to. If you're working full time and just looking for a hobby course, don't do this one. Or do it across two sessions, instead of trying to get it done in the 5 weeks. Don't do it if you want to learn how to use cloud computing - only if you want to research in cloud computing or need to know how it works under the hood.
This course would benefit from a slower pace and more detailed examples. I feel that everything was rushed and minimal guidance was given, which made the course not particularly enjoyable for me. Without some background in computer science, I think this would be a real struggle to get through at all.
Sorry for the lengthy review, I hope it helps someone decide whether this course is really for them.

The educational material do not meet the expected quality, as of many other courses. The instructor speaks too fast, with a lot of technical jargon in between each sentence, but does not interact with the user by annotating the slides. So, I had to keep moving my eyes around (reading compact text, or complex graphs) to try to make a connection between his words, and which part of slides he is speaking about.
Furthermore, I have excellent Python and Fortran and CUDA background, but not C++, so, I cannot do the final exam. I am gonna drop out of this course.

The programming assignment is very old style C code/C++ not using any of the updated/newer syntax. It required spending more time relearning old coding conventions than actually implementing the algorithms and such. Was very frustrating. The material and course overall is great, save that assignment, which is required to pass.

My experience with this course was mostly positive. The lectures were helpful and fairly brief compared to a standard university class. The instructor provides good examples and the presentation slides are a good study guide. FWIW, the workload for this course is much less than a graduate level CS course (at least in my experience).
The negatives about this class: The homework/quiz assignments often asked you to solve a scenario more complicated than anything discussed in lecture, and there's no book to go read to get a better understanding. This made for an unnecessarily frustrating quiz process. Other reviewers have already criticized the programming assignment, and I concur with most of the complaints. You end up wasting too much time working on things other than learning content related to the course.

Felt like the assignments were too good for what was covered. We have to Google outside the course material to understand many concepts. But loved the fact that we got chance to try some hands on. That clarified a lot about Gossip style protocol. But the contents in the course about Chandy-Lamport algorithm needs SURE restructuring. It is NOT AT ALL adequate to answer the assignments. I request professor, Coursera to have a second look at these topics.
von Tarun B•
Not very engaging. Information overflow and poorly delivered lectures where the instructor is just reading from slides. I don't recommend paying for this, it is better to just check out the syllabus and read about this stuff online.
Note to instructor: Very simple concepts were explained using overly complicated language. Also, please refrain from over using the word 'essentially'.
von Oren E•
I thought the class was quite good. Dr. Gupta is very knowledgeable about the subject and presents the material well.
This is listed as a beginner level class. I think it is worth noting that this could only be considered as beginner for people that already have a decent background in computer science. People not familiar with algorithm will likely sind themselves somewhat challenged.
The quizzes are quite difficult, which is fine, however the only feedback you get is pass/fail. To give the student a better understanding of the material, it may be helpful to have a one or two question quiz after each lecture. These should be of the complexity that is expected on the exam (as compared to the in-lecture questions which are quite easy). For these mini-quizzes, solutions with explanations could be provided.
Lastly, the programming project is in C/C++. Many people seem to be complaining about why this isn't in a different language. Perhaps more of an explanation for the language choice is in order. (e.g. it wouldn't really make sense to implement distributed processing algorithms in Java due to the speed requirement.) C/C++ is listed as a prerequisite, so if you don't have this in your background, you should be prepared to spend some time learning at least the minimum, particularly use of pointers and pointer arithmetic.

This instructor is fantastic. He is exceptionally thorough and his delivery is very good as well. This is a course definitely worth taking if you are interested in learning more about the cloud.

The instructor seems to be in a hurry to get over the course and the course should rather be called a theoretical introduction to concepts in distributed computing. The slides are confusing with no animation. The programming assignment statement is just vague. Wouldn't recommend folks to pay and attend this. This may at best be for audit.
von Mona L•
The instructor's lecture sounded too robotic and I feel like he didn't make any effort to explain some of the principles or simplify the course to the audience. It feels like he just copied concepts and pasted them into the lecture and then read them quick.
von Bruno M•
Having to do the coding assignment in c++ is kind of bad :/
von Wojciech K•
This is a great course with a good balance of just theory and concepts, with practical ideas and exercises. The programming exercise can be a bit annoying, but was enjoyable nonetheless.

This course not good for me.
von Vavilala D R•
very happy with the course. got to know new concepts. assignments are awesome. enjoyed working on them. enjoyed the course. it would be good if we get a color and original certificate.

Very interesting courses and topics. The course has nothing to envy to normal university courses and it is indeed a university course (from the online CS degree from U of I). I am really glad that this material is available to the public. Few points on which the course can be improved:
* On the slides there are different notations and formats that are used. Making all of them uniform would help better in the understanding of the contents.
* When providing topics and algorithm, please also provide also actual examples and explanation of what kind of problems we are trying to solve. For example it is not clear what problem we are trying to solve with the Multicast Problem, since some time ordering algorithm seems more appropriate.
* The code in the programming assignment is terrible. It needs a serious review. It is supposed to be C++ code, but in reality it uses many of the C-style programming paradigm that are very outdated. Also all the creation/handling of raw pointers are completely wrong, many times a simple reference could be used. Encoding messages have never been more complicated, like JSON or BER encoding never existed. You should thrive for improving the code quality so that students can have a good example of a very well written code.

The course introduces many cloud computing concepts, and briefly highlights the trending technologies. It is a good starting point for the beginners, it also contains a set of challenging quizzes and final exam, one could not pass unless s/he masters the course contents. finally there is the programming assignment which would not sound easy until you pass it.
von Ajith K B•
The course provided a good overview on various topics at sufficient depth. The assignments and quizzes were challenging enough allowing one to understand the concepts in good detail.
von Deepti S•
Seems a bit difficult in the beginning, especially if there is a long break from academics but a thorough and in depth course
von Alexey P•
The topics and lectures are pretty good. Some of homework in my opinion is too time consuming, especially week4-5.
An acceptable course to those who want to have an insight to cloud computing.
von Patrick S•
High quality lectures are brought down by a terrible programming assignment and unresponsiveness by staff regarding the assignment.
The professor has very good step-by-step explanations of the algorithms as well as detailed notes. Although it may seem abstract or unrelated, the content is very relevant to the state of cloud computing.
...now to the assignment... The assignment has unclear instructions, a bad C++ (not 11) code template that can even prevent you from running the code due to hard-coded buffer sizes and not actually using sizeof() properly, and a lot of the ugly code is in regions you are not allowed to modify. Expect to spend more time ( > 3x as much) trying to figure out the template than actually trying to apply the concepts of the course.
von Roman P•
Too bad the final exercise is in C++, and not even in the modern C++ with smart pointers and other improvements. Makes you spend more time on the language issues than on the cloud computing algorithms.
von HUANG Z•
I think the lecturer should not just "reading" the PPT. And the subtitle should not contain those words representing lecturer's sound ( e.g. uh).
von Carmine L•
The lessons are a bit boring, an interactive blackboard or animated examples could help.

Nice overview of all the cloud concepts but lags in difficulty level for beginners
