My customers are always asking me who do you recommend we buy Azure training from. I am a Microsoft Certified Trainer and I specialize in Office 365, Azure and exam preps. I tell them...do NOT pay for a training class or online subscription models they aren't worth it.
Microsoft provides more and better training then any training provider out there. The problem is it is not all in one location so hard to find.
Here is more free training https://www.microsoft.com/en-us/learning/azure-training.aspx
Microsoft's official certification site https://www.microsoft.com/en-us/learning/certification-overview.aspx#bcc-section this is where they also have free online training videos and links to prepare for an exam. Yes some of the links go to articles, but that is because it is easier and faster for them (anyone) to update an article then update a training video or series of videos.
So here is a list of Microsoft's free Azure training sites.
https://www.microsoft.com/en-us/learning
https://mva.microsoft.com/
Microsoft has more free Azure online training in LinkedIn Learning, I really like these as they are good series. https://www.linkedin.com/learning/microsoft-azure-core-functionalities-2
If you want hands on lab training Microsoft even has hands on labs for free, and I have taken all companies hands on lab training and Microsoft's is best by far. https://www.microsoft.com/handsonlabs .
There is also training and articles found in the certification exam pages.
https://www.microsoft.com/en-us/learning/mcsa-cloud-platform-certification.aspx
This is the application developer exam for Azure https://www.microsoft.com/en-us/learning/exam-70-532.aspx .
This one is a combination of both application development and infrastructure so I recommend it.
https://www.microsoft.com/en-us/learning/exam-70-533.aspx
Then after you have your two certifications above and have earned your MCSA you only need to take one more exam 70-535 for Architects to earn your MCSE. https://www.microsoft.com/en-us/learning/exam-70-535.aspx
Always expand the Training and Resources and you will see the free resources to learn this topic.
70-538 Azure DevOps certification is coming in the next few months. https://www.microsoft.com/en-us/learning/exam-70-538.aspx
Free DevOps training is here: https://mva.microsoft.com/training-topics/devops that includes testing.
