Sometimes, the numbers just make sense!

Oracle took the crystal ball out and predicted that by 2025, 80% of businesses are projected to fully move to the cloud. Statista reported that the public cloud market alone generated $130 billion. This goes to show the flow of money in the cloud market. 

It should come as no surprise that cloud computing is the #1 most in-demand hard skill, according to LinkedIn. There are many job opportunities in this industry. Site reliability engineers (SRE), cloud developers, enterprise account executives, customer success managers, solution cloud architect are just few of the high paying roles available in the cloud industry.

In this blog we will talk about AWS Cloud Developer.

But first, what is a cloud engineer?

A cloud engineer is a full stack developer who knows how to use cloud services of a public cloud provider such as Amazon Web Services (AWS) or Azure or Google Cloud Platform (GCP).

Amazon Web Services (AWS) is one of the most popular cloud providers that has over 175 cloud computing applications.

So, how much does a cloud developer make?

As per job site Glassdoor, the average annual pay for a Cloud Developer in the United States is $100,465/year. So, it makes sense to know about cloud and get certified.

Exam tips for AWS Developer Associate Certification

  • If you are not a native English speaker, you are eligible for a 30-minute time extension. If you are a nervous test taker, use this time to your advantage.
  • If you prepare thoroughly with enough hands on experience, you’d have enough time at the end. However, plan your time wisely. Bookmark the questions you aren’t sure of, but give each question at least a minute to read thoroughly.
  • Often times you may find answer to questions in other questions. Bookmarking will come in handy here and at the end when you review the questions, see if any other question has answer to your problem question.
  • Often times the answer is in the question itself. Look for keywords like most, least, cost-effective, scalable, highly available etc.
  • Because this is a developer level exam, you may see some command level questions. Example – What would this command do, when to use it, etc.
  • Know how to do Read Capacity Units (RCU) and Write Capacity Units (WCU) calculations. You might get one or two questions on determining RCU/WCU.

Conclusion

Certifications are great ways to show employers what you know about technology. You can demonstrate your skills by using certifications that prove you’re an expert in the field. Employers may be impressed by having several certifications, but if they see that you’ve been certified for something that’s outdated, or doesn’t apply to the job you want, then you won’t impress them. AWS Developer certification is just one of the many reputed ones out there, that’s in demand and increases your chances to get hired.

Finally, certifications are not just about validations of knowledge, but also about showing commitment, dedication, willingness to learn and the drive for staying at the forefront of innovation. Sometimes this demonstrates more to people than the actual certification stands for.
