The contents of this course are really practical and to the point. The examples and notebooks are also up to date and are very useful. i really recommend this course if you want to start with Spark.
Great Course but this would have been even a better course if more concepts and details were covered in it. Anyways, still a great course for beginners

This was not especially well made. A number of the examples shown on videos don't necessarily work or are outdated with respect to the platform or the datasets you're working with. Perhaps, greater attention should be given towards guiding the student to the github repo were the notebooks are up to date and working properly. Otherwise a good course, definitely not introductory to cloud, if that's what you're looking for. There is some high level programming that I'm defnitely not prepared for but the notebooks are so complete that I did not have to apply myself so much. So on the one side I appreciate the ease of the notebooks but, on the other side, have some doubt as to the practical knowledge acquired. Hoping later courses in the specialization clear this out for me.

It was difficult to follow the IBM cloud setup since it was constantly changing, I couldn't understand the reason for using python2.7 since its only 10 months before it wont be supported by the community. Sometime instructors' pronunciations were not clear and and thus added extra confusion. However, instructor do actively participate in helping with discussions. Audio and video quality were also not very good. This course is a very basic introduction to IBM cloud and general stats. Prior knowledge of spark is useful. Overall the course is nice introduction to IBM cloud if one is interested.

This is a good introduction and overview to working with Spark. The assignments are very straightforward and I think that the biggest benefit is learning how to set up a work-station in IBM and working with your notebooks there. One thing that I think should be improved is the version of Python and Spark that is being demonstrated: the lectures should update to Python 3 and we also have Spark 3 by now; focus should be on data frames instead of RDD. Also, lots of links need to be updated because their references are deprecated and so no longer exist.
This is a very basic course even if it's my first interaction with Apache Spark. For sure, it gives some information. But I found the timeframes stated too long. You feel like you'll get a lot of information. But a week of videos and readings and assignments can be done in 1.5-4 hours depending on your experience how much time you spend on assignments.
Also, there are many materials that are outdated. That should be fixed if this course carries the name of IBM.

The coding part is easy to comprehend but the course does not offer much opportunity to practice and learn the coding. The assignments are straight forward and doable. Sometimes it is hard to read the code in the videos even at 720p as it appears blurred. The subtitles cover some of the formulae shown at the bottom of the video and there are many mistakes in subtitles.
Overall, it is a good introductory course that gives you an idea of about Apache Spark.

The Course touches the important topics related to scalable data. The quizzes & assignments were challenging and the fun to solve.
Though the course touches the important topics, it does not go deep into it. Some of the codes provided in the video didn't work with the current version of python and spark. For example the code for finding the median. The Cognitive IOT app development method provided was broken and it wasn't the right way to do it.

I was really looking forward to this specialization but from the very first course I am really disappointed. The videos refer to various not updated information and then suddenly we are expected to do an assignment that was not at all explained in the course. I am not saying it is difficult, or not achievable but to be honest until now (week 2) it feels mostly like a waste of time.. Really sorry for this review.
