Cloud Computing என்றால் என்ன?

Cloud computing is the delivery of computing services — servers, storage, databases, networking, software, and analytics — over the internet on a pay-as-you-go basis. It eliminates the need to own and maintain physical infrastructure, enabling organizations to scale resources up or down on demand.

What is Cloud Computing?

Cloud computing is the on-demand delivery of IT resources via the internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centers and servers, organizations rent access to computing power, storage, and applications from cloud providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).

Cloud Service Models

Cloud computing is organized into three primary service models:

  • IaaS (Infrastructure as a Service): Virtual machines, storage, and networking. You manage the operating system, middleware, and applications. Examples: AWS EC2, Google Compute Engine, Azure Virtual Machines.
  • PaaS (Platform as a Service): Managed application platforms where the provider handles the OS, runtime, and infrastructure. You deploy your code. Examples: Heroku, Google App Engine, AWS Elastic Beanstalk.
  • SaaS (Software as a Service): Fully managed applications accessible via the web. You use the software; the provider manages everything. Examples: Salesforce, Google Workspace, Slack.

    • Cloud Deployment Models

  • Public cloud: Resources shared across multiple customers on provider infrastructure. Most common and cost-effective.
  • Private cloud: Dedicated infrastructure for a single organization. Higher security and control, higher cost.
  • Hybrid cloud: Combination of public and private clouds, allowing data and applications to move between them.
  • Multi-cloud: Using services from multiple cloud providers to avoid vendor lock-in and optimize for specific capabilities.

    • Benefits of Cloud Computing

  • Scalability: Scale resources up or down instantly based on demand — no capacity planning or hardware procurement.
  • Cost efficiency: Pay only for what you use. No upfront capital expenditure on hardware.
  • Global reach: Deploy applications across data centers worldwide for low-latency access from anywhere.
  • Reliability: Major cloud providers offer 99.95%+ uptime SLAs with built-in redundancy and disaster recovery.
  • Speed to market: Provision new environments in minutes instead of weeks, accelerating development and testing cycles.

    • Cloud Computing Challenges

  • Security and compliance: Storing data on shared infrastructure requires careful attention to encryption, access controls, and regulatory compliance (GDPR, HIPAA, SOC 2).
  • Cost management: Without governance, cloud costs can spiral as teams spin up resources and forget to shut them down.
  • Vendor lock-in: Deep reliance on provider-specific services makes migration difficult and expensive.
  • Data transfer costs: Moving large amounts of data out of cloud providers (egress) can be surprisingly expensive.
  • Latency: Some workloads require ultra-low latency that cloud infrastructure cannot match compared to on-premise hardware.

    • Cloud Computing and Automation

    Cloud computing is the foundation of modern automation platforms. Workflow engines, browser automation containers, API gateways, and data processing pipelines all run on cloud infrastructure. The ability to spin up isolated execution environments on demand makes cloud computing essential for scalable, reliable automation.

    இது ஏன் முக்கியம்

    Cloud computing has become the default infrastructure model for modern businesses. It enables organizations of any size to access enterprise-grade computing resources without massive capital investment, and it underpins nearly every SaaS application, automation platform, and data service in use today.

    • A startup using AWS to host their entire application stack — compute, storage, database, and CDN — without buying a single server

    • An enterprise running a hybrid cloud setup with sensitive data on private infrastructure and customer-facing applications on public cloud

    • A data team using Google BigQuery (cloud-based data warehouse) to analyze terabytes of data without managing database servers

    அடிக்கடி கேட்கப்படும் கேள்விகள்

    SaaS (Software as a Service) is one category of cloud computing. Cloud computing encompasses IaaS (virtual infrastructure), PaaS (application platforms), and SaaS (complete applications). SaaS delivers ready-to-use software; cloud computing is the broader umbrella that includes the infrastructure and platforms those applications run on.

    Major cloud providers invest billions in security and typically offer more robust protection than most organizations can achieve on their own — including physical security, encryption, DDoS protection, and compliance certifications. However, security is a shared responsibility: the provider secures the infrastructure, but you must secure your data, access controls, and application configurations.

    On-premise means running hardware and software in your own data center. Cloud computing means renting those resources from a provider over the internet. On-premise offers maximum control but requires significant capital investment and IT staff. Cloud computing offers flexibility and scalability with lower upfront costs but introduces provider dependency.
