Study Notes
Cloud Computing Deployment Models
- Hybrid cloud involves a combination of two or more private, community, or public clouds.
- Public cloud refers to a cloud computing environment made available by a third-party vendor over the public internet. It is accessible to anyone and is often used for public services or applications.
- Private cloud is a cloud computing environment that is owned and operated by a specific organization and accessible only to authorized users within that organization.
- Community cloud involves a cloud environment shared by multiple organizations with common interests or goals, typically hosted in a way beneficial for those organizations.
- Hybrid cloud combines multiple types of clouds, including public, private, and community clouds, to leverage the advantages of each.
- Private cloud can be on-premise or off-premise, meaning it can be physically located within the organization's own facilities or hosted by a third-party provider.
Cloud Service Models
- Software as a Service (SaaS) provides applications and software to the customer in a utility-based model accessible from a thin client interface like a Web browser.
- Platform as a Service (PaaS) offers programming languages and tools to deploy applications onto the cloud infrastructure. The focus is on providing the platform for application development and deployment, rather than the underlying infrastructure itself.
- Infrastructure as a Service (IaaS) provides computing resources such as servers, storage, and networking on demand, allowing customers to build and manage their own applications and services on top of the provided infrastructure.
Advantages and Risks of Cloud Computing
- Cost-effectiveness is a primary advantage of cloud computing, as businesses can pay for computing resources on an hourly basis and scale up or down as needed.
- Flexibility is another benefit, allowing businesses to access resources on demand and quickly adapt to changing business needs without the need for significant upfront investments.
- Over-provisioning is a risk that arises from allocating more resources than needed. It can lead to wasted resources and increased costs.
Key Concepts in Cloud Computing
- Autonomic Managers are software components responsible for self-managing the cloud infrastructure and applications. They are responsible for monitoring, analysis, planning, and execution of tasks.
- MAPE-K stands for Monitor, Analyze, Plan, Execute, and Knowledge in the autonomic control loop of autonomic managers. It outlines the steps involved in the automated self-management process.
- Cloud Economics is the study of how to optimize cloud resources and costs, with the goal of achieving the best possible return on investment.
- Pay-as-you-go is the pricing model recommended in cloud economics, encouraging only paying for what you use.
- Peak usage is a term used to describe the highest level of resource demand within a given period, and it’s a valuable resource for calculating cloud costs more precisely.
Cloud Computing and Cloud Providers
- Businesses opt for cloud providers to avoid the capital expenditure and ongoing maintenance associated with establishing and maintaining their own infrastructure.
- Cloud service provider is typically known for its ability to deliver applications and services over the internet using a public cloud environment.
- Cloud computing encompasses a broad range of services delivered over the internet, from software and infrastructure to data storage and analytics.
Cloud Service Model Definitions
- Infrastructure as a Service (IaaS) offers computing resources like servers, storage, and networking on demand. It gives customers full control over the operating systems, applications, and other software.
- Platform as a Service (PaaS) provides a platform to develop, run, and manage applications without the need for managing the underlying infrastructure. It focuses on providing the tools and environment for application development and deployment, rather than the infrastructure itself.
Cloud Deployment Model Features
- Community cloud involves a cloud environment shared by multiple organizations with common interests or goals. One of its key features is its shared infrastructure and resources, which can lead to cost savings and improved efficiency.
