Cloud has become a default primer track at Accenture because so much client delivery now runs on public cloud platforms. For freshers without hands-on cloud experience, the cloud primer can feel like a new language full of acronyms. The reassuring truth is that the primer tests conceptual understanding, not console wizardry. You do not need to launch a single server to clear it; you need to understand the vocabulary and the why behind each idea.
This guide explains the cloud and AWS concepts the primer most commonly covers: the service and deployment models, the shared responsibility model, core compute and storage services, networking and security basics, and how to study them efficiently. We use AWS terms as examples because they appear most often, but the same concepts map to Azure and Google Cloud.
What the cloud primer expects from you
The cloud primer checks that you understand cloud computing as a concept and can reason about its building blocks. Expect definition questions, scenario questions that ask which service model fits a situation, and a few that test the shared responsibility model. You are not expected to write infrastructure code or remember exact pricing.
Because the material is largely conceptual, the primer rewards clear mental models over rote memorisation. If you can explain in your own words what the cloud is, why organisations move to it, and who is responsible for what, you are most of the way to a pass.
Cloud service models: IaaS, PaaS and SaaS
The three service models are the backbone of the cloud primer. Infrastructure as a Service gives you virtual machines, storage and networking that you configure yourself, offering the most control. Platform as a Service provides a managed environment where you deploy applications without managing the underlying servers. Software as a Service delivers ready-to-use applications over the internet, where you simply use the software.
A reliable way to remember the difference is by what you manage versus what the provider manages. With IaaS you manage the most; with SaaS you manage the least. Scenario questions often describe a need and ask which model fits, so practise mapping situations to the right layer.
- IaaS: virtual machines, storage, networking; you manage the most
- PaaS: managed platform to deploy apps; provider runs the servers
- SaaS: ready-to-use software; you just use it
- Remember by what you manage versus what the provider manages
Deployment models and the shared responsibility model
Know the deployment models: public cloud, where resources are shared and delivered over the internet; private cloud, dedicated to one organisation; and hybrid cloud, which combines both. Multi-cloud, using more than one provider, sometimes appears too. Be able to give one reason an organisation might choose each.
The shared responsibility model is a favourite primer topic. The cloud provider is responsible for the security of the cloud, meaning the physical infrastructure, while the customer is responsible for security in the cloud, meaning their data, access management and configuration. Misunderstanding this split is a common reason candidates lose marks, so make sure the line is crisp in your mind.
- Public, private, hybrid and multi-cloud deployment models
- Provider secures the cloud: hardware, facilities, core infrastructure
- Customer secures in the cloud: data, identity, access, configuration
- Know one business reason for each deployment model
Core AWS compute and storage concepts
On the AWS side, a few flagship services appear repeatedly. EC2 provides resizable virtual servers, the classic example of IaaS compute. S3 is object storage for files and data, durable and accessed over the internet. Lambda runs your code without you managing servers, the headline example of serverless computing.
You should recognise these by what they do, not by configuration detail. Know that EC2 is for general compute, S3 is for object storage, and Lambda is for event-driven serverless functions. If you can match a workload to the right service, you can answer most AWS scenario questions in the primer.
- EC2: virtual servers, the classic IaaS compute service
- S3: durable object storage for files and data
- Lambda: serverless, event-driven code execution
- Regions and Availability Zones for resilience
Networking, security and cost basics
A handful of supporting concepts round out the primer. Understand at a high level what a virtual private cloud is, the idea of identity and access management for controlling who can do what, and why encryption protects data at rest and in transit. You do not need deep networking knowledge, just the purpose of each control.
On cost, know the core cloud value proposition: you pay for what you use rather than buying hardware upfront, and you can scale resources up or down on demand. The shift from capital expenditure to operational expenditure is a concept the primer likes to test, so be ready to explain it simply.
A focused prep plan for the cloud primer
Because the cloud primer is conceptual, spread a short, consistent effort over a few days rather than cramming. Spend your first session on service and deployment models, your second on the shared responsibility model and core AWS services, and your third on networking, security and cost basics.
After each session, immediately attempt practice questions on that topic so the definitions stick. A topic-wise cloud question bank lets you isolate weak areas, and a timed mock that mixes service models, the responsibility model and AWS services rehearses the exact format you will face. Reviewing only the questions you got wrong is the fastest way to firm up the vocabulary.
- Session 1: service and deployment models
- Session 2: shared responsibility model and core AWS services
- Session 3: networking, security and cost basics
- After each session, drill practice questions, then take a timed mock
Frequently Asked Questions
Do I need hands-on AWS experience for the cloud primer?
No. The cloud primer tests conceptual understanding, not console skills. You do not need to launch servers or write infrastructure code. Focus on understanding service models, the shared responsibility model, and what core services like EC2, S3 and Lambda are used for.
What is the difference between IaaS, PaaS and SaaS?
They differ by how much you manage. With IaaS you manage virtual machines, storage and networking yourself. With PaaS the provider manages the platform and you deploy applications. With SaaS you simply use ready-made software. Remember it as: you manage the most with IaaS and the least with SaaS.
What is the shared responsibility model?
It splits security duties between provider and customer. The provider secures the cloud itself, meaning the physical infrastructure, while the customer is responsible for security in the cloud, meaning their own data, identity, access and configuration. This split is a very common primer question.
Which AWS services should I focus on?
Focus on the flagship services that appear most often: EC2 for compute, S3 for object storage, and Lambda for serverless functions. Recognise them by what they do and the kind of workload each suits, rather than memorising configuration details.
Is the cloud primer the same as an AWS certification?
No. The cloud primer is a foundational baseline check, much lighter than a formal AWS certification exam. It introduces concepts you may later deepen through certifications, but for the primer you only need a clear conceptual grounding.
How should I practise for the cloud primer?
Study one concept area at a time, then immediately attempt questions on it using a topic-wise cloud question bank. Finish with a timed mock that mixes service models, the shared responsibility model and core AWS services, and revisit only the questions you got wrong.
