Study Notes
Introduction to Cloud Computing
- Cloud computing provides a means to access applications as utilities over the internet
- Users can create, configure, and customize applications online
- Users can access database resources via the internet from anywhere as needed, without managing the resources themselves
What is Cloud?
- Cloud refers to a network or the internet
- A cloud is something located at a remote location
- Cloud services can be delivered on public networks (e.g., WAN, LAN) or private networks (e.g., VPN)
- Applications like email, web conferencing, and CRM are examples of cloud-based services
What is Cloud Computing?
- Cloud computing involves manipulating, configuring, and accessing applications online
- Cloud computing offers online data storage, infrastructure, and applications
- Cloud computing combines software and hardware-based computing resources delivered as a network service
Cloud Computing Architecture
- Cloud computing architecture connects users with storage, application, and infrastructure components through a cloud
Basic Concepts
- Deployment Models categorize how a cloud is accessed (Public, Private, Hybrid, Community)
- Service Models (IaaS, PaaS, SaaS) describe different cloud service types
Deployment Models
- Deployment models define cloud accessibility, specifying the location of the cloud
- Cloud access can be public, private, hybrid, or community
Public Cloud
- Public clouds are accessible to the general public
- They often have a lower level of security compared to other cloud types
Private Cloud
- Private clouds are accessible to a specific organization
- They offer increased security due to their private nature
Community Cloud
- Community clouds are accessible to a group of organizations
- They share resources and infrastructure within the group
Hybrid Cloud
- Hybrid clouds combine features of public and private clouds
- Critical activities are typically performed using a private cloud, while non-critical activities are performed using a public cloud
Service Models
- Service Models are reference models for Cloud Computing
- They categorize cloud computing into three categories: IaaS, PaaS, and SaaS
Infrastructure as a Service (IaaS)
- IaaS delivers technology infrastructure as an on-demand, scalable service
- Provides fundamental resources like physical machines, virtual machines, and virtual storage
- Typically billed based on usage
- Usually a multi-tenant, virtualized environment
- Can be combined with managed services for OS and application support
Platform as a Service (PaaS)
- PaaS provides a runtime environment for applications, along with development and deployment tools
- Offers facilities for the complete lifecycle of building and delivering web applications
- Applications are typically developed considering the specific platform
- Multi-tenant environments are common
- Highly scalable multi-tier architecture is a key feature
Software as a Service (SaaS)
- SaaS allows users to access software applications as a service
- It’s a software delivery methodology for licensed multi-tenant access to software and its functionalities through a web-based service
- Typically billed based on usage
- Usually a multi-tenant environment
- Highly scalable architectures are common
Advantages of Cloud Computing
- Lower computer costs
- Improved performance
- Reduced software costs
- Instant software updates
- Improved document compatibility
- Unlimited storage capacity
- Increased data reliability
- Universal document access
- Latest version availability
- Easier group collaboration
- Device independence
Disadvantages of Cloud Computing
- Requires a constant internet connection
- Does not work well with low-speed connections
- Features might be limited
- Can be slow
- Stored data might be lost
- Confidentiality issues for stored data
Cloud Storage
- Create an account using a username and password
- Content is stored in the cloud linked to the account
- Access content from any computer with Wi-Fi
Downloading for Storage
- Download a cloud-based app to your computer
- The app resides on your computer
- Save files using the app
- The app synchronizes with the cloud when connected to the internet
- Access the cloud from any internet connection
