AWS vs Azure vs OCI: which cloud course should you pick?

Short answer: if you have no strong reason to choose, pick AWS. It has the most job postings, the most learning material and the most recognisable certification. Pick Azure if you are targeting large Indian IT services companies or already know Windows and Microsoft tools. Pick OCI if you are building an Oracle database career, or you want a path with far fewer competing candidates.

That is the one-paragraph version. The rest of this article explains why, so you can check the advice against your own situation.

First, what a "cloud course" actually teaches

All three courses train you for the same kind of job: a cloud engineer or cloud administrator who builds and runs infrastructure for a company. Servers, storage, networks, user access, backups, monitoring and cost control, except that the hardware belongs to Amazon, Microsoft or Oracle instead of sitting in the company's own data centre.

The first third of any good cloud course is therefore identical across platforms: Linux, networking basics, storage concepts, identity and security. Only after that do the platforms diverge. This is why switching clouds later in your career is normal. Your first choice is not a life sentence.

AWS: the largest market

Amazon Web Services has been the market leader for over a decade. In practice, for a fresher in India, that means three things:

• Most job postings. Search any job portal for "cloud engineer" and the majority mention AWS.
• Most start-ups and product companies. If you would rather work at a growing company than a large services firm, AWS is the common denominator.
• Most recognisable certification. The AWS Certified Solutions Architect – Associate is the certification recruiters ask about by name.

The downside is competition. Because AWS is the default choice, a lot of people hold the same certificate. What separates you is hands-on ability, which is why our AWS program runs for 7 months with live labs rather than a few weeks of slides.

Azure: the enterprise and services-company choice

Microsoft Azure dominates in companies that already run on Microsoft: Windows Server, Active Directory, Office 365. In India that includes most large IT services companies, banks, insurers and government projects.

Choose Azure if:

• you are targeting TCS, Infosys, Wipro, HCL, Capgemini, Cognizant or similar companies, where Azure projects are plentiful;
• you have any Windows administration background, since Azure identity and management will feel familiar;
• you want the AZ-104 Azure Administrator certification, which maps directly to entry-level administrator roles.

Our Microsoft Azure program follows the AZ-104 track and, like the AWS course, you can sit the certification exam on campus at our Pearson VUE authorised test centre in Kolkata.

OCI: fewer jobs, far fewer candidates

Oracle Cloud Infrastructure is the smallest of the three in overall market share, and it would be wrong to pretend otherwise. But the job market is not just about the number of openings. It is about the ratio of openings to qualified candidates, and that ratio is where OCI shines.

Companies that run Oracle databases, which is most banks, telecom operators and large ERP users, are moving those databases to OCI. They need people who understand both the database and the cloud around it, and those people are rare.

Choose OCI if:

• you are already on, or planning, the Oracle DBA path. Our Database Architect program plus OCI is the combination our placement team sees hired fastest in the Oracle ecosystem;
• you prefer a specialist path where you compete with dozens of candidates rather than thousands;
• you want a cloud where your training institute has genuine depth. SHA Career Hub grew out of an Oracle consulting company, and OCI is where our trainers work day to day.

One of our alumni, Atri, put it plainly in his Google review: he enrolled in the OCI course, got "hands-on scenarios and deep technical insight", and is now a senior OCI administrator at an MNC.

The decision in five questions

1. Do you want to be an Oracle DBA, or do you already have Oracle skills? Choose OCI.
2. Are you targeting the big Indian IT services companies specifically? Choose Azure.
3. Do you have Windows or Active Directory experience? Choose Azure.
4. Do you want the widest range of employers, including start-ups? Choose AWS.
5. Still can't decide? Choose AWS, or take the Multi Cloud Administrator program, which covers all three.

What does not matter as much as you think

Which cloud "pays more". Entry-level salaries for cloud roles in India cluster in a similar band, roughly ₹3.5 to 6 LPA depending on city, company and how well you interview. The platform moves the number far less than your hands-on ability does.

Which cloud is "the future". All three are growing. Companies increasingly use more than one, which is exactly why multi-cloud skills exist.

Which cloud your friend chose. Their background is not yours. A B.Com graduate targeting a bank and a B.Tech graduate targeting a start-up should probably make different choices.

What to check before you enrol anywhere

Whichever platform you pick, the course matters more than the logo. Ask any institute these questions:

• Is the training live and instructor-led, or recorded videos with a chat window?
• How many hours of hands-on lab work are there, and do you get your own cloud environment?
• Does the course map to a specific certification exam, and can you sit it there?
• What does placement support actually include: CV preparation, mock interviews, introductions to companies, or just a job portal login?
• Can you talk to placed alumni?

Our answers to all five are on the course pages and on the Placements page. If you want them in person, a counsellor will walk you through them on a free call.
