Big Data on AWS

Good to get overview of all aws services as beginner level. Rest depend on hands-on, practice and how much we explore services by ourselves.

Although the course teaches you concepts of Big Data on AWS, the course does not give all of the code to follow along, you have to code it and get lost sometimes, also some sections are very fast, not for beginners.

So far so good - simple and easy to understand. I will update my rating after I'm done with the course

video editing is poor. screen starts out blurry. lots of spelling errors/typos. overall quality is lacking

A good course if you want to start your career in Big Data using AWS. Each modules& videos are perfectly organized.

Seemed pretty detailed. I wasn't expecting quite so much programming. I hope it is required on the exam.

Have just started it and found there could be better way of explaining some of the concept like Row based and columnar database concept.

The course was OK, and Arpan knows his stuff. However, there are some serious issues that need to be corrected: 1) The biggest issue is that there is very little supporting documentation, and what there is strangely organized. For example, lesson 47 (Kinesis demo commands) is a single page with the commands used in lesson 46. While these are copy and pastable, they're too late - by the time you realize they're there, you've already completed lesson 46. Udemy course documentation is supposed to be in files attached to the lesson. Arpan clearly knows this, as a couple of the lessons (such as #42) have files attached. But the vast majority of them don't. Arpan mentions a GitHub repository a couple of times, but doesn't provide a link. He does have a GitHub page (https://github.com/arpansolanki?tab=repositories) but none of the repositories there appear to relate to this course. Also, his web site (http://www.arpansolanki.com/) is down. 2) Another major problem is that Section 5 of the course covers a deprecated service, AWS Machine Learning. This section should be updated to cover SageMaker. AWS no longer allows new users to create ML models, so it's impossible to follow the demo even if you want to. 3) The practice exam at the end has answers with the questions, in some cases on the same line as the question. This makes it impossible to read a question without seeing the answer, so the exam is useless for practice. This is a shame, as there was obviously a lot of effort involved to create it. Ideally, the exam should be interactive, with the solution displayed only after the candidate has selected an answer. At the very least, the answer key should be a separate document from the exam itself. These are the major issues. There are others throughout: 4) The Redshift copy command gets "invalid operation" unless the Workbench/J connection is set for autocommit. The course should mention this. 5) Lesson 42 (Kinesis Agent) should mention that it's necessary to set the Kinesis endpoint in agent.json 6) Lesson 58 (QuickSight) should mention that it's necessary to authorize QuickSight to access the specific S3 bucket containing the data. Also, the data rused by this demo (file bank-additional-full.csv, a download from UCI or Kaggle) must be massaged somewhat (change semicolons to commas, change "y"/"n" to 1/0) before use. 7) Lesson 73 (Write Files to EMRFS Demo) should mention that it's necessary to add SSH access to the security group (as well as where to get the needed data, which is tricky to find on the Internet). 8) Lesson 106 (GSI and Queries) should also discuss LSI and explain the differences between GSI and LSI. 9) Lesson 150ff (Flight Data Analysis) needs data and code. Some of it is on third-party site https://www.bogotobogo.com/DevOps/AWS/aws-qwiklabs-RedShift.php I know this is a long review. I hope Arpan takes it in the spirit intended. There's a lot of excellent material in this course and it could be a really good one if these structural issues can be corrected.

I bought this course when it was bundled with other Big Data certification course (from Frank and Stephane). The rationale for taking this was to go through the Exam Questions. However, the exam questions from this courses are very poor (either copy from official samples from AWS) or not explanatory enough. Also, the exam questions mention ANSWER right-away in last option, this is hurting the spirit of exam taker who wants to see and evaluate answers. e.g. Refer following question. The answers are provided right on the last line. And, no explanation! In fact the answer here are WRONG (A & D are correct for Even Distribution Style). Looks like these questions are copied from some other website...Google it ;-) An administrator needs to design a strategy for the schema in a Redshift cluster. The administrator needs to determine the optimal distribution style for the tables in the Redshift schema. In which two circumstances would choosing EVEN distribution be most appropriate? (Choose two.) A. When the tables are highly denormalized and do NOT participate in frequent joins. B. When data must be grouped based on a specific key on a defined slice. C. When data transfer between nodes must be eliminated. D. When a new table has been loaded and it is unclear how it will be joined to dimension. Answer: B,D ---- [Updates] See another question about Storage for Firehose. None of options are correct as KDF does NOT Store anything. It has buffer, but that it not storage. The question is however relevant to Kinesis Data Streams (KDS), as it "can store" by-default for 24 hours. How long does each Kinesis firehose delivery stream stores data records in case the delivery destination is unavailable? a) 12 hours b) 24 hours c) 48 hours d) 72 hours Answer: b Though I could not effectively use Exam Questions, I updated review from 2.5 to 3 rating just because of hands-on sections (e.g, IOT, Presto, HIVE-DynamoDB, etc)

The course contains most of what you need for the exam. Aprpan could work on pronunciation, but there are no parts that would not be understandable. And yes, I completed the exam today :-)

crisp short videos. beautifully explained. never get tired watching. i think its because he made all the videos with minimum duration covering each point in each video. I found this approach a best way to learn.

Mr. Arpan you have done a Great Job by explaining the whole topic with plenty of Examples and hands-on. Detailed explanation for IOT and Redshift was really useful and was very well explained. Thanks

This course is good and has lot of hands on but there is no Certificate specific information. The practice exam given has answers to the questions just below them so we cannot really solve the practice test and test our competency. A very good Positive is there are lot of links given in the course which are very use full for the exam and helped me pass the exam as well .

brief overview of each aws components, neatly explained. needs notes or important summary points for each slide explained

this is a great course. thank u for the demo videos those are great. can't wait for new sections on Glue and Spark
