Study Notes
Cloud Computing Overview
- Cloud computing is a way for companies to access servers, software, and data over the internet.
- Cloud servers are located in data centers around the globe.
- Using cloud computing, users do not have to manage physical servers or software applications on their own machines.
What is Cloud Computing?
- Cloud computing refers to servers that are accessed over the internet, and the software and databases that run on those servers.
- Cloud servers are located in data centres all over the world.
- Users and companies do not manage physical servers themselves or run applications on their own machines.
Introduction to Cloud Computing
- Cloud computing is adopted by many companies due to cost-cutting, reduced maintenance, and increased data capacity.
- The "pay-as-you-go" principle is a major driver in the transition to cloud computing. This means users only pay for services they use.
Types of Clouds
- Public Cloud
- Provided by third-party vendors like AWS, Azure, and GCP, accessible to the public.
- Private Cloud
- Deployed within an organization's own data center, providing complete control and enhanced security.
- Hybrid Cloud
- Combines private and public cloud resources to provide flexibility and security.
Types of Cloud Services
- Infrastructure as a Service (IaaS):
- Provides virtualized computing resources (servers, storage, networking).
- Users manage their own applications and data on top of the provided infrastructure.
- Platform as a Service (PaaS):
- Provides a platform for building, testing, and deploying applications, including development tools, frameworks and pre-configured environments.
- Users focus on application code without managing underlying infrastructure.
- Software as a Service (SaaS):
- Delivers software applications over the internet so users can access them via a web browser.
- Users do not manage underlying infrastructure or software.
Cloud Architecture
- Front End (User Interface): The user interacts with software using applications.
- Back End (Servers): Where applications are processed.
- Cloud Network: Connect the systems together.
Advantages of Cloud Computing
- Cost-effectiveness: Pay-as-you-go pricing models
- Scalability: Easily increase or decrease resources in response to demand.
- Flexibility: Access data and services from anywhere with internet access.
- Reliability: Cloud providers maintain high availability and redundancy of services.
- Security: Cloud providers often have robust security measures in place to protect data.
Challenges of Cloud Computing
- Security: Concerns about data breaches and privacy issues.
- Vendor lock-in: Difficulty switching providers once applications are deployed.
- Cost Management: Managing cloud spending can be complex.
- Lack of control: Users have limited control over the underlying infrastructure.
- Compliance: Need to comply with industry regulatory guidelines.
Cloud Security Fundamentals
- Confidentiality: Authorized access to data.
- Integrity: Assurance data is accurate and unaltered.
- Availability: Data and services are accessible when required.
- Authenticity: Verifying the source of data.
Cloud Security Services
- Authentication: Verifying user identity.
- Authorization: Granting access rights.
- Auditing: Tracking activity and access to data.
Cloud Network
- A network of interconnected devices enabling communication and data exchange between devices.
- Multiple types
- Local Area Network (LAN)
- Wide Area Network (WAN)
- Metropolitan Area Network (MAN)
- Virtual Private Network (VPN)
Questions
- Define cloud computing, advantages and disadvantages.
- Differentiate between public, private, and hybrid cloud.
- Explain the different cloud service models (IaaS, PaaS, SaaS).
- Discuss cloud security concerns.
- Explain the role of networks in cloud computing.
