Why do you need to learn from Infra domain knowledge as certified Cloud Professional ?
In the current IT World Cloud computing became regular practice for any IT Professional. Any cloud services we use, we need to know the current/traditional infrastructure setup. But every IT professional may not have that background/knowledge to understand. Because in this industry each of us played different roles.
The Infra activities handled IT Professional only will come to know this knowledge and will have experience. But the industry needs every IT employee need to know this knowledge apart from the Cloud service provider [Ex: AWS, Azure, GC, etc..] products operations. [Eventhough, if you are a certified Solutions architect with that Cloud service provider.]
Then only whoever the professionals are certified they will be able to use these products/services and implement them under cloud setup. Hence the Infra domain knowledge or experience is mandated for every IT professional who is working for Cloud services or in that infra setup. I have been hearing during Cloud professionals recruitment the interviewers are keeping some questions on this area also. If one understand the Network domain setup then only they will be able to design the Cloud architecture. Hence more employers are worried to have this domain knowledge with the Certified and recruited Cloud professionals.
I have started a Cloud Practices group to educate/share the IT professionals with this domain knowledge. The below link can be used to join/apply:
Let us assume an international bank has daily transactions files in different global regions. Those need to be shared across globe for different business users purpose in each country. They should be able to access them for their dashboards. This example talks on this kind of cross data sharing scenario using “S3-Bucket Cross Region Replication [CRR]”.
At the end of this blog, you can find the same scenario simulation using AWS S3-Buckets.
