You think that aws has highest cloud market shares(50%) and azure and gcp have very less cloud market shares. We have assumed that AWS has lots of opportunities in market, We think that learning AWS and getting good package so that we can easily survive for 10 years from now. But it's won't work in reality, because learning AWS only will not help to boost your career. 1. You are already developer in some company who has knowledge on Java Or python or any other programming language and learning AWS is right choice definitely, it will add more weightage to the resume and more chances to achieve the dream package. 2. You must have heard that people saying you don't require any programming language to learn aws. But that's not true, you need to write scripts and sometimes you need to write lambda function and cloud formation or Terraform and jenkins pipelines, most of the companies expecting knowledge on the these services. If you want to crack jobs on AWS you should have very good knowledge on those services. 3. Although you might be aware of aws and you hold the certification of aws but you don't have 100% chances to get a job, because companies need people who knows the aws +devops tools (very good knowledge on at least 3 tools) + scripting ( python or shell) and + strong knowledge on unix( 100% mandatory) aws + any development knowledge (java/python/any other) 4. Most important point, there are lot of people who are available for aws /devops(already working and new people) and Ameerpet Institutes are working very hard to release more people on aws, so there is huge competition for aws compared to 2018 and 2019 5. You might be confused to what to learn, here is the better idea, learn azure/azure devops and gcp. Yes it is having less jobs but at the same time very less people are available for azure and gcp and certification will be added advantage. 6. Most of the people don't have genuine experience, since Ameerpet exporting lot of people into aws market almost like 100s of people in a month, so think before learning aws in 2020. 7. Learn devops tools jenkins docker chef kubernetes ansible gcp azure/azure devop.
