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.

It's hard to love this course. It deserves 3 stars, but as truly unique which gives you some in-depth understanding of how does cloud computing works underhood, I'm giving it 4 stars.
-> Unique content about cloud computing internals
-> Really hard programming assignment. It includes local grader, so you're not that blind in how you work is graded on coursera side. It's a good way to use this grader to mark you progress.
-> Broad coverage of topics
-> The programming assignment. It's not that hard as an exercise itself to learn gossip protocol, but the cumbersome C++ code written in C style can get you nuts. There are only one assignment about one particular topic, presumably to be done across all 5 weeks step by step. I did it at second week and once completed, i was pushed myself to complete the course after, I would prefer to have small medium difficulty exercises on each week subject.
-> Explanations and proofs. Some topics are poorly covered, most of the time you'll hear only sketch or overview of proof without going into details. Many times lector just say something like "you can figure this out by yourself". Only pseduo code will be shown (except Hadoop examples copy-pasted from official docs)

Overall I really enjoyed this course, and I think I learned a lot, so thank you!
However I think there were some things that could be improved.
Firstly the quality of the code provided for the programming assignment was very low. It contains a lot of things that are far from modern c++ best-practices (e.g. using raw arrays instead of std::vector, mixing malloc and new, using new where there is no reason to use it, using raw pointers when references would be fine, missing consts, macros, ...). There were also some relatively minor bugs: the first log message doesn't print with the correct prefix, and the grading script as provided doesn't run (IIRC it was because the #! isn't on the first line). Since this course could be some people's first introduction to C++ I feel that it's important to set a good example, and to keep the code simple and safe.
Secondly the symbols used for things were often inconsistent between slides, which was occasionally confusing but should be easy to fix.
Despite these issues I still think this is a great course, it just could be a little bit better.

While I understand that C++ had EmulNet, which must have been pretty handy when designing the assignment, it's really far from ideal to learn this sort of thing with such a low abstraction level language. I would have very much preferred to spend my time learning the algorithms more deeply, but I actually spent most of it remembering pointer arithmetic and memory management.
What I'm saying is C++ is fine, but it would have been better if we could use a language on which we can actually focus on the logic (which is not simple to start with), not data representation, memory management and what not.
Other than that, I loved the lectures. The examples are a bit outdated, but the concepts are solid, which is what really matters. Thank you very much!

The content of this course is great and the video lectures are of good quality. If you are looking for a university quality distributed systems course this is the best course i've found. Where this course lacks is in the outdated and tedious programming project and some quiz's that have questions not covered in lecture. The programming project will have you using c-style c++ code so be prepared. It has inconsistent use of data structures and types in its template code that you cannot modify and you will spent a significant amount of time doing memcpy to encode and decode data for char buffers. The quiz's have questions not covered in lecture like Chandy-Lamport questions around process state recordings. BEWARE THIS IS NOT A COURSE FOR BEGINNERS

The coverage is good and there is a clear linkage of the concepts included in the beginning with the rest of the contents as they flow in - not just throughout this course, but also for the entire specialization. It would really help if the instructor would speak a little slowly (a bunch of words get garbled) and if the slides have lesser content (have more slides and redesign). That way, the instructor might not feel forced to talk so much per slide and the listening might be a little easy on the ear.
However, that does not take anything away from how that content is organized - that is good and takes you the flow rather well.

I generally like the course because it expanded my horizon and taught me new concepts which are important in my work. However I think the presentation can be improved. I also miss a more in-depth comparison between the various related concepts. The programming assignment is not designed in the most test-friendly way. It contains some snippets that are half-baked and unclear instructions to provide the missing code. It required some reverse engineering to understand the template code. This can be seen by some as a fair requirement but I expected a more structured and unambiguous approach.

1. Need more tutors to answer the question
Some of the questions in the quiz are badly written and some of us did not understand and tried to ask. And almost no one responds the questions in the "discussion forum" when you reach the end of the course.
2. C++ project assignment
The project claims to use C++, but mixed the C and C++ and doesn't follow C++ best practices. It is very bad for people who have to learn C++ to finish this project since they will get confused by plenty of C code in C++.

I enjoyed the contents and homeworks. Overall the delivery was very good, and I have grasped a lot.
The main reason that I won't give 5 stars is the program assignment. I have spent and wasted 3 weeks to work on the tools, yes, tools, not the subject matter. Course should clearly indicate that the assignment only works in Linux/UNIX environment, and need to further test the scripts in most popular Linux OS platforms, different c++ versions, and different python versions.

I think the course content is very rich and useful. The topics are well explained and have examples. I'm really happy with the course content. The only part of the course I think it needs to be improved is the programming assignment. I think there should be more options of languages, like Java, for example. And the C++ code should be reviewed because it's very confusing and those who don't have familiarity with C++ will certainly have difficulty.

Very interesting course if you want to learn about inner workings of distributed systems. Lecturer was very knowledgeable and provided good examples. Exams and quizes were pretty challenging and fun. I love that there was a practical programming assignment. I would only suggest to tweak the template for programming assignment as it was a little bit limiting. And maybe allowing for different programming languages other than C++.

A solid introduction into the field of distributed systems. I especially liked the material on distributed hashing. The Quiz questions, in particular section 5 could use a bit of clarification, as I sometimes found it difficult to understand exactly what was being asked. That said the lecture slides, and organization of the material was quite good, and I recommend the course.

The content of the course - quite good, well explained
The quizes - mostly ok, but some of the questions were repetitive
The programming assignment - the C++ skeleton is quite bad bad, uses ugly code andneeds to be rewritten; also the chcker has an unpreditable behavior; sometimes, grades you with 90, sometimes with 30.

The course is quite interesting and useful in terms of lectures and tests, especially tests with written answers. But it needs refinement in terms of the task (outdated and there are no options for java or other popular languages), and a little more information about multicast with examples of problem solving)

Actually I wanna give it 3.5 star. This course is released a few years ago so it might not be maintained very well. Also the assignments are a bit of uncovered by the slides. The code assignment is not well code styled. The c code are integreted with c++ which makes me feel not good.

It was a good course for the start. The concepts were taught with ease examples were there for more understanding. The programming assignment could be made more finesse, as there was a lot of issue like windows incompatibility, 64 bit incompatibility, memcpy passing vector in ENSend.

Great course but the main problem is that very little help is available. Programming assignment is not able to understand meaning not able to find how to start (what should be the first step?)
pace is little fast. learned a lot about Cloud Computing. Homeworks are really challenging.

The lectures are clear and informative. The quizes pose the right amount of challenge. The template code provided for the programming assignment is terrible, but the assignment itself is not that complex and quite doable for most people with object oriented programming experience.

The course gave me an interesting overview of different problems from the cloud computing field. The course start looks little bit slow, but later it gets more interesting. However I was disappointed with code quality of the assignment framework.

GREAT course ,the concepts and theories have been explained thoroughly. But I also believe providing a few reference materials would have been better for a theory oriented course like this one.overall still the best could theory course online

The course was without doubt amazing.
The videos was pretty good and the Quiz at the end of each week helped a lot to recollect stuff.
The programming assignment was a little hard though and it wasn't clear as to what we were supposed to do.

Good content overall .. I wish there were more references to the content (links to articles and readings). The assignment skeleton code needs to be looked into (it is really bad.. super hard to understand what is going on)

A very good course covering various topics in a duration of 5 weeks. Some of the topics needs a little more explaination. The homeworks make sure that one understands the topics covered during the week.

Solid distributed systems' fundamentals class. The programming assignment was really evaluating my reverse and software engineering skills rather than my grasp of distributed systems' fundamentals

Great lectures. However, the starter code for the programming assignment is quite atrocious. Overall, would highly recommend to anyone wanting to learn high level concepts in distributed systems.
