CLOUD SERVICES

What “the cloud” means today

Cloud computing allows individuals and businesses to access powerful computing resources through remote data centers managed by providers such as AWS, Microsoft Azure, and Google Cloud. Instead of owning servers, you rent what you need—compute, storage, databases, analytics, AI tools, and more.

  • It offers flexibility, scalability, and cost efficiency.
  • You only pay for what you use.
  • Resources can be deployed globally within minutes.

Cloud services are used for everything from email and data backup to AI, app development, and streaming platforms like Netflix.

Main types of cloud services

Cloud services are generally grouped into three major models:

1. Infrastructure as a Service (IaaS)

Provides virtualized computing resources such as:

  • Virtual machines
  • Storage
  • Networks

This is the most flexible model, letting you manage operating systems and applications.

2. Platform as a Service (PaaS)

Provides a readytouse environment for developers to build, test, and deploy applications without managing servers. Examples include app hosting platforms and development frameworks.

3. Software as a Service (SaaS)

Delivers complete applications over the internet. Examples: Gmail, Office 365, Salesforce. Users don’t manage infrastructure or platforms—just use the software.

Additional modern cloud categories

Serverless computing

You run code without managing servers; the cloud provider handles scaling automatically.

AI and analytics services

Cloud platforms now offer machine learning, big data analytics, and AIpowered tools.

Storage services

Highly scalable object storage, file storage, and backup solutions.

Cloud deployment models

Cloud can be deployed in three ways:

  • Public cloud — shared infrastructure managed by providers like AWS or Azure.
  • Private cloud — dedicated infrastructure for one organization.
  • Hybrid cloud — mix of onpremises and cloud environments.

Why cloud matters today

Cloud computing enables:

  • Lower costs (no hardware to buy)
  • Instant scalability
  • Global reach
  • High performance
  • Faster innovation

As a tech organization, InfoSys can help implement cloud services by doing four essential things:

1. Assessing business needs

We analyze what the client company wants—scalability, cost savings, security, remote access—and decide which cloud model fits (public, private, hybrid).

2. Designing the cloud architecture

We plan how applications, data, networks, and security will work in the cloud.

3. Migrating systems and data

We move servers, databases, apps, and files from onpremises to cloud platforms like AWS, Azure, or Google Cloud.

4. Managing and securing the cloud

We monitor performance, optimize costs, set up backups, enforce security policies, and provide ongoing support.
