Study Notes
Understanding Cloud Computing: Exploring SaaS, Service Models, and Deployment Models
Cloud computing is a paradigm where computing resources—such as servers, storage, databases, networking, software, and analytics—are delivered using the internet. Instead of owning physical hardware, users can access these resources on-demand, paying only for what they use.
Software as a Service (SaaS)
SaaS offers ready-to-use applications to customers who pay based on usage or subscription. Popular SaaS solutions include Salesforce, Google Docs, and Microsoft Teams.
Service Models
Cloud computing offers three main service models:
- Software as a Service (SaaS): Pre-built applications delivered through a web browser.
- Platform as a Service (PaaS): An environment for building, testing, and deploying applications, with little to no management of the underlying infrastructure.
- Infrastructure as a Service (IaaS): Virtualized compute, storage, and network resources on which customers build their own applications.
Deployment Models
Cloud computing provides three deployment models:
- Public Cloud: Cloud services offered by third-party providers, accessible through the public internet.
- Private Cloud: Cloud services offered by a single organization, either managed in-house or by a third-party provider with dedicated resources.
- Hybrid Cloud: A combination of public and private cloud services, offering the best of both worlds.
Virtualization and Hypervisor
Virtualization is the creation of virtual, software-based versions of computing resources, such as servers or storage. A hypervisor is the software that manages these virtual resources. Cloud providers use virtualization and hypervisors extensively to optimize the delivery of their services.
Types of Storage
Cloud storage can be categorized into:
- Object Storage: Data is stored in objects, which can be accessed using a unique identifier (URL) and simple HTTP or HTTPS requests.
- Block Storage: Data is stored in blocks, which can be attached to virtual machines and accessed using standard file system protocols.
- File Storage: Data is stored in a hierarchical file system, which can be accessed using standard file system protocols like SMB or NFS.
Cloud computing has become a fundamental part of the modern technology landscape, offering agility, scalability, and cost savings. Its availability and versatility continue to drive innovation and shape the future of business and computing.
