I have cracked the Azure AZ-900 exam in 7 days. I will share the plan and tutorials to crack the exam.
I will also provide several tips and tricks to remember and draw analogy to understand the concepts.
The exam is divided into four categories: –
1 day is enough for the cloud concept.
Let’s cover the category 1: –
SYLLABUS ( Understand cloud concepts )
• Describe the benefits and considerations of using cloud services
• Understand terms such as high availability, scalability, elasticity, agility, fault tolerance, and disaster recovery
•Understand the principles of economies of scale
•Understand the differences between Capital Expenditure (CapEx) and Operational Expenditure (OpEx)
•Understand the consumption-based model
Tips and Tricks: – Assume Vertical Scaling is stacking more CPU on one another connected in series connection. The size occupied on a table is same because the new servers are on the existing server. Assume Horizontal scaling as keeping new server next to the existing server. This will occupy more space on the table.
Elastic: – Automatically adding or removing new resources (e.g. server) based on the spike or drop in demand.
Cloud services can be used across the world and it is fast and secure.

Tips and Tricks: – CapEx is just like buy a laptop/computer with heavy configuration first and perform your business and then earn from business then.
Advantages of CapEx:- When need to predict the expense before the start of the project.
Advantages of OpEx:- When demand is fluctuating.
Public Cloud :- Azure is a public Cloud provider.
Private cloud:- You create a cloud environment in your own datacentre.
Hybrid Cloud:– Combines public and private clouds
