Cybersecurity is an huge opportunity for IT professionals. Let me give you a proof of it. Alphabet (Google) has acquired over 200 companies till date. Please pay attention to it acquisition done in  March 2025.  With its largest acquisition being the buy of Wiz (a cloud security company [wiz.io]), for $32 billion.

In the list of 3 top expensive companies first and third are in cybersecurity business. Google paid  $32,000,000,000 ($32 billion) to WIZ Israel Company (Cloud Security) which is its highest buying cost ever.

I will dig deeper in cloud security later.

• First of all we will see some use case example of cloud.
• Why are more than 90% organizations using cloud?
• Little bit history of cloud computing.
• What is cloud computing?

Okay so let's start with some use case scenarios of cloud:

 🛒 Scenario 1. The Local Grocery Store That Expanded Online

📌 Use Case: Cloud for Scalability and Cost Efficiency

Imagine you own a small grocery store in your neighborhood. You have a steady flow of customers every day. But, during festive seasons like Diwali or Christmas, the number of shoppers triples. Your store becomes crowded, and customers get frustrated due to long queues.

You want to expand online to meet the demand. You are well aware about the fact that customers increased during only festive time. 

Moreover, you’re worried about:

• Storage space for customer data and product catalog.
• Server crashes due to high traffic during sales.
• High costs of buying new servers for temporary spikes.
• Maintenance cost of devices.
• Skilled professions need to configure the devices.
• Electric Power cost, etc. 

Cloud Solution: 

You discussed all these issue with your friend. Who are an IT professional and he suggested the below solution to you.

Instead of purchasing expensive servers, you should use cloud computing.

• You create an online store hosted on cloud servers.
• During regular days, you pay for the basic server capacity.
• During festive sales, the cloud automatically scales to handle the extra traffic.
• Once the sale is over, the cloud scales back down, and you only pay for what you used.

The benefits will be:

• Cost-Effective: No need to buy permanent hardware for temporary demand.
• Fast and Reliable: Your website handles thousands of orders without crashing.
• Global Reach: You can sell to customers beyond your locality.

✅ “Using the cloud is like having a grocery store with expandable walls. It grows when you have more customers and shrinks when business is slow. Without you having to pay for extra space all the time.”

🔥Scenario 2: Remote Work and Collaboration for a Small Business

📌 Use Case: Cloud for Collaboration and Accessibility

Company: ABC Consultants. It is a small IT consulting firm with remote employees across multiple locations.

Challenge:

• Employees need real-time access to shared documents.
• Secure, remote access to company data is required.
• Collaboration on projects must be seamless.

Cloud Solution:

✅ Cloud Service: Google Workspace (GCP) or Microsoft 365.

✅ Architecture:

• Document Storage: Google Drive or OneDrive for real-time collaboration.
• Communication: Google Meet or Microsoft Teams for virtual meetings.
• Email & Productivity: Gmail or Outlook for email communication.
• Version Control: Real-time document collaboration with automatic versioning.
• Cloud Security: Multi-factor authentication (MFA) and data encryption.

Benefits:

• Anywhere Access: Employees can work from any device and location.
• Real-Time Collaboration: Multiple users can edit the same document simultaneously.
• Automatic Backup: No risk of data loss due to automated backups.
• Security: Controlled access and encrypted data storage.

⚙️ Scenario 3: Cloud-Based Disaster Recovery for a Financial Institution

📌 Use Case: Cloud for Disaster Recovery and Business Continuity

Company: Global Bank Ltd. – A multinational financial institution.

Challenge:

• The bank needs a disaster recovery (DR) solution. To ensure continuous operations during cyberattacks or natural disasters.
• They need automatic failover and rapid recovery with minimal downtime.

Cloud Solution:

✅ Cloud Service: Microsoft Azure or AWS.

✅ Architecture:

• Primary Data Center: On-premises infrastructure.
• Disaster Recovery Site: Azure or AWS DR region.
• Replication: Use Azure Site Recovery or AWS Backup to replicate data in real time.
• Failover Process:
  • In case of a disaster, the system automatically switches to the DR region.
  • The RPO (Recovery Point Objective) is <15 minutes, ensuring minimal data loss.
  • The RTO (Recovery Time Objective) is <1 hour, ensuring rapid recovery.
• Data Backup: Regular backup to Amazon S3 or Azure Blob Storage.

Benefits:

• Business Continuity: Zero downtime with automatic failover.
• Cost Savings: Pay only for the DR site when used.
• Compliance: Meets financial industry regulations for data redundancy.

⚙️ Scenario 4. The DevOps Team That Automated Everything

📌 Use Case: Cloud for Infrastructure as Code (IaC) and Automation

 A mid-sized software company called CodeForYou. The software demand continuously increasing. Company needs to take some urgent steps for more and better infrastructure. To meet their clients demand.

 DevOps team need to perform many tasks like:

• Team frequently deploys new features and updates for their clients.
• They need to test and replicate environments quickly.
• Manual server configuration takes too much time and introduces errors, etc.

😩 If company think to establish its own infrastructure they may face below Problems:

• Inconsistent environments cause bugs during production releases.
• Deploying new features takes hours or days due to manual steps.
• Infrastructure changes are prone to human error.

Company want solution as quickly as possible. And you got this assignment to explore solution. You have idea about cloud computing and you researched on it. After collecting lots of information you came up with solution and you presented it.

💡 The Cloud Solution:

Moves to the cloud and uses Infrastructure as Code (IaC):

• The team writes scripts to automatically deploy servers and environments.
• With cloud automation, they can replicate the same environment in minutes.
• The cloud automatically scales the infrastructure based on demand.
• They implement auto-healing servers that restart when they fail.

🎯 Key Benefits Explained to Clients:

• Consistency: The same script creates identical environments every time.
• Speed: Automated deployments reduce release time from days to minutes.
• Reliability: Self-healing servers prevent downtime.

✅ “Using cloud automation is like having a robotic assistant. That builds and manages your servers perfectly every time, without human error.”

I hope with these use case scenarios you would be able to see how cloud can be beneficial in different situations.

In part-2 we will explore the market size of the cloud from cybersecurity perspective.

Also share your experience while using cloud.

Is your company using cloud?

If yes for what purpose and which cloud provider?
