To work efficiently with cloud platforms, you need foundational expertise across programming, operating systems, networking, virtualization, and database management. Complementing these technical skills are deployment strategies like Agile development and DevOps, along with hands-on familiarity with cloud platforms, APIs, machine learning and AI services.
Together, these prerequisites for cloud computing enable you to build scalable, secure, and automation-ready systems optimized for modern application lifecycles.
If you want to learn essential skills to help you understand what is cloud computing, the following courses can help you succeed.
Programming languages are prerequisites for cloud computing because every interaction with cloud platforms, whether provisioning infrastructure or writing serverless functions, requires scripting or development skills. Most cloud services offer SDKs and APIs in multiple languages, allowing you to build, manage, and scale your workloads without relying solely on web interfaces.
Example Scenario:
A SaaS startup in Pune uses Python and Boto3 to automate resource provisioning on AWS. They run a FastAPI microservice on AWS that fetches user data from DynamoDB and sends scheduled reports via SES, cutting manual operations by over 80%.
Code Example:
import boto3
# Initialize S3 client
s3 = boto3.client('s3')
# Upload a file to an S3 bucket
s3.upload_file('invoice.pdf', 'business-reports-bucket', '2025/invoice.pdf')
print("File uploaded successfully.")
Output:
File uploaded successfully.
The script uses boto3 to upload a file to Amazon S3. It automates part of your reporting pipeline in cloud-based applications, reducing reliance on manual uploads and improving data consistency.
Now, let’s understand security and recovery, which are also key prerequisites for cloud computing.
Security and recovery define how well your cloud architecture resists unauthorized access and restores functionality after disruptions. As key prerequisites for cloud computing, they involve implementing identity controls, encryption standards, compliance logic, and data redundancy across services. Without these controls, even highly available systems remain exposed to configuration drift, data loss, or operational downtime.
Example Scenario:
A fintech firm in Mumbai manages sensitive KYC documents in a PostgreSQL database hosted on Amazon RDS. To meet RBI compliance, you encrypt data using customer-managed keys (CMKs) via AWS KMS, enforce MFA on admin roles, and automate nightly backups to a second region.
Code example:
import boto3
# Encrypting and storing a simple message using AWS KMS
kms = boto3.client('kms')
text = b"Confidential: User PAN data"
response = kms.encrypt(
KeyId='alias/customer-key',
Plaintext=text
)
ciphertext_blob = response['CiphertextBlob']
print("Encrypted text (bytes):", ciphertext_blob)
Output:
Encrypted text (bytes): b'\x01\x02...\x91\xac'
The script uses AWS Key Management Service to encrypt a plaintext string. In real applications, this would be used to encrypt personally identifiable information (PII) before storing it in cloud databases, aligning with India’s data protection standards.

Networking governs how cloud resources communicate with each other and with external systems. It involves configuring IP ranges, routing traffic, securing communication channels, and ensuring low-latency access to services.
As one of the core prerequisites for cloud computing, networking ensures scalability, isolation, and high availability of cloud-based applications. Without it, provisioning secure, accessible, and performant environments becomes unmanageable.
Example Scenario:
A fintech startup in Bengaluru uses AWS VPC with custom subnets and NAT gateways to isolate public and private services. You configure Elastic Load Balancing to distribute traffic across EC2 instances and implement AWS Security Groups to restrict SSH access by IP range. DNS routing is managed via Route 53, enabling dynamic subdomain configuration for microservices.

The program will help you gather expertise on cloud computing, big data analytics, and more those are critical for enterprise-grade applications.
Virtualization abstracts physical computing resources into software-defined environments that can be replicated, scaled, and managed independently. As one of the core prerequisites for cloud computing, it allows you to provision compute, storage, and network resources without tying them to specific physical hardware.
Virtualization supports multi-tenancy, improves infrastructure efficiency, and lays the groundwork for containers, orchestration, and resource elasticity.
Example Scenario:
A retail analytics firm in Delhi uses VMware ESXi on-premises for development and testing, while production systems run on Azure Kubernetes Service (AKS). By virtualizing the entire stack, compute, storage, and network, they achieve cost savings during low-traffic months and rapid scaling during festival sales.
Code Example:
# Dockerfile to containerize a Python Flask app
FROM python:3.9-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt
COPY . .
CMD ["python", "app.py"]
Output:
Container builds successfully and runs the Flask web server on port 5000.
This Dockerfile creates a container for a Python Flask application. It contains the runtime environment and dependencies, enabling consistent deployment across virtualized infrastructure like AWS ECS, Azure AKS, or local VMs.
Let’s understand operating systems and why they are critical prerequisites for cloud computing.
Operating systems control how cloud resources behave at the most fundamental level. They manage system calls, kernel operations, memory allocation, user permissions, and I/O scheduling, which directly impact application performance in virtualized and containerized environments. A deep understanding of OS internals is a core prerequisite for cloud computing, especially when deploying distributed systems or troubleshooting performance bottlenecks in production.
Example Scenario:
An Indian logistics company hosts its route optimization engine on an Ubuntu-based EC2 instance. Engineers use systemctl to manage background services, tune TCP parameters for faster network communication, and configure cron jobs for batch updates. The team's ability to manage OS-level services reduces latency during peak delivery hours.
Agile development enables continuous delivery of features and fixes by emphasizing short development cycles, fast feedback, and strong collaboration across teams. As one of the essential prerequisites for cloud computing, it complements cloud-native architectures by supporting automation, containerization, and frequent deployment. Agile methodologies ensure that cloud-based applications remain adaptable, scalable, and aligned with evolving user needs.
Example Scenario:
A SaaS-based HRMS provider in Noida adopts Scrum to deliver biweekly updates for its payroll module. Each sprint integrates user feedback into the next release. You use GitLab CI for automated testing and Azure DevOps for deployment. This setup reduces regression bugs by 60% and accelerates new feature rollout across multi-tenant cloud environments.

Cloud service platforms provide on-demand access to compute, storage, networking, databases, and application services, all abstracted from physical infrastructure. Familiarity with major platforms is a key prerequisite for cloud computing because each offers specialized tools, billing models, security frameworks, and deployment pipelines.
Deep platform knowledge allows you to choose the right service for your workload, whether it’s serverless processing, distributed training, or real-time analytics.
Example Scenario:
An IT services firm in Chennai manages client workloads across AWS, Azure, and GCP. They deploy a scalable ML model using AWS SageMaker, set up Microsoft SQL Server clusters on Azure for legacy apps, and run real-time data pipelines. Their engineers switch between these platforms based on SLA requirements, tool support, and pricing efficiency.

Now, let’s understand the different types of cloud frameworks that are essential prerequisites for cloud computing.
Cloud deployment models define how infrastructure and services are provisioned, managed, and accessed by organizations. Choosing the right model is a critical prerequisite for cloud computing because it impacts performance, data security, compliance, and cost structure. Public, private, and hybrid cloud models each have architectural trade-offs, and selecting the wrong type may lead to scaling limitations or regulatory risks.
Public Cloud: Public cloud resources, compute, storage, networking, are delivered by third-party providers like AWS, Azure, or GCP. These are provisioned on shared infrastructure via multi-tenant models. Public clouds are ideal for startups and SaaS products that require instant scalability and low upfront investment.
Private Cloud: Private clouds are dedicated environments either on-premises or hosted externally with exclusive access. Built using technologies like OpenStack, VMware, or Azure Stack, they offer enhanced control over infrastructure. They’re best suited for industries with strict regulatory requirements such as healthcare, banking, or government.
Hybrid Cloud: Hybrid models combine public and private cloud infrastructure, often connected through VPNs or direct links. They offer the flexibility to run secure workloads on-premise while scaling demand workloads on the public cloud. Tools like AWS Outposts, Azure Arc, and Google Anthos help unify management across hybrid environments.
Example Scenario:
A digital payments company in Gurugram uses a hybrid cloud setup. Their customer-facing application runs on AWS (public cloud) for elasticity, while sensitive transaction data is stored in a private OpenStack cloud to comply with RBI’s data localization mandate. Azure Arc is used to monitor and manage both environments through a single control plane.
DevOps integrates software development and IT operations into a unified workflow focused on automation, collaboration, and rapid delivery. It plays a foundational role among the prerequisites for cloud computing by enabling continuous integration, repeatable deployments, infrastructure versioning, and proactive system monitoring.
DevOps becomes essential for maintaining velocity and system in a cloud environment where services must scale on demand and updates need to roll out without downtime.
Example Scenario:
A digital payments company in Hyderabad uses Terraform to define its entire AWS infrastructure, including EC2, VPCs, and IAM roles. Jenkins pipelines handle CI/CD for their transaction processing service, and AWS CloudWatch tracks system health, triggering alerts for high CPU usage or dropped API requests. This setup reduces deployment time from hours to under 10 minutes and minimizes rollback risks through version-controlled infrastructure.
Code Example:
# .github/workflows/deploy.yml
name: Deploy to AWS
on:
push:
branches: [ "main" ]
jobs:
build-and-deploy:
runs-on: ubuntu-latest

aws lambda update-function-code --function-name myLambdaFunction --zip-file fileb://function.zip
Output:
All tests passed.
Lambda function successfully updated.
This GitHub Actions workflow installs dependencies, runs tests, and deploys a Lambda function on AWS whenever code is pushed to the main branch.
Artificial Intelligence (AI) enables machines to perform tasks that typically require human cognition, like recognizing patterns, processing language, and making data-driven decisions. Within cloud environments, AI services integrate deeply with compute, storage, and data pipelines, allowing you to build intelligent systems without managing complex infrastructure.
As one of the emerging prerequisites for cloud computing, AI helps automate decisions, personalize user experiences, and optimize backend operations through models deployed at scale.
Example Scenario:
A health-tech startup in Bengaluru processes diagnostic reports using AI models trained on AWS SageMaker. You use NLP to interpret doctors’ notes via Amazon Comprehend Medical and deploy a model endpoint to classify disease likelihoods. Their system supports thousands of inferences daily, reducing manual triage time by 40%.
Let’s understand the importance of APIs for cloud computing in detail.
APIs define how software components communicate across systems, enabling modular and scalable application development. In cloud environments, APIs are the backbone of service orchestration, automation, and integration. They’re a core prerequisite for cloud computing because almost every cloud service, compute, storage, ML, security, exposes functionality through REST or GraphQL APIs. Building, consuming, and securing APIs is fundamental for deploying and managing cloud-native applications.
Example Scenario:
A ride-sharing app startup in Mumbai integrates real-time driver location tracking using REST APIs connected to GCP Firebase. The customer-facing dashboard uses GraphQL to fetch only relevant fields like ETA and driver ID from their microservices architecture, improving response times by 30% on 4G networks.
Example Code:
from flask import Flask, jsonify, request
app = Flask(__name__)
@app.route('/status', methods=['GET'])
def status():
return jsonify({"status": "API is running", "region": "India"})
if __name__ == '__main__':
app.run(debug=True)
Output:
GET /status → {"status": "API is running", "region": "India"}
The Flask-based REST API returns a simple health check response. Such endpoints are standard in cloud apps to monitor microservices via tools like AWS CloudWatch or Azure Monitor.
Now, let’s understand how database management play a critical role in maintaining the integrity of cloud computing for enterprise-grade applications.
Database management involves designing, deploying, querying, and optimizing structured and unstructured datasets in the cloud. It’s a foundational prerequisite for cloud computing because data powers almost every cloud application for transactions, analytics, personalization, or logging.
Cloud-native databases offer features like auto-scaling, high availability, and managed backups, allowing you to focus on schema design, query efficiency, and integration rather than server maintenance.
Example Scenario:
An e-commerce company in Pune uses Azure SQL Database to manage its product inventory and order tracking. Logging user activity across devices uses MongoDB Atlas hosted on AWS. Weekly sales reports are run on BigQuery. You monitor query latency and optimize indexes to maintain —sub-second performance during seasonal traffic peaks.
Now, let’s understand does cloud computing needs coding for organizational applications.
Whether cloud computing requires coding depends on your role and responsibilities. Technical roles like cloud developers and DevOps engineers need strong programming skills to build, automate, and scale cloud-native applications.
In contrast, infrastructure-focused or governance roles may emphasize configuration, policy enforcement, or platform administration over deep coding. However, even basic scripting knowledge enhances efficiency in almost every cloud function by enabling automation and customization.
Role-Based Coding Requirements
Use Case:
A logistics startup in Bengaluru manages infrastructure across AWS and Azure using Terraform to automate multi-cloud provisioning. Python scripts handle alerting, log processing, and credential rotation, reducing manual effort. This coding-driven workflow enables faster deployments, consistent environments, and efficient scaling across regions in real-time cloud computing operations.
Now, let’s explore what are the common tools and technologies for cloud computing.
Cloud computing tools span across development, automation, security, monitoring, and orchestration. Coding tools like IDEs, Git, and CI/CD platforms are critical for writing and deploying cloud-native applications, while non-coding tools support infrastructure and disaster recovery.
Containerization (e.g., Docker, Kubernetes) and Infrastructure as Code (e.g., Terraform, CloudFormation) are central to building scalable and repeatable environments. Mastery of these technologies ensures reliable deployment, efficient resource management, and security compliance in multi-cloud operations.
Here’s a breakdown of coding and non-coding tools, along with examples of popular platforms used in cloud environments.
