Study Notes
Introduction to Cloud Computing
- Computing is being transformed into a service model similar to utilities (water, electricity).
- Users access services based on needs, regardless of location.
- Cloud computing is the latest approach to utility computing.
- It's a technological advancement in designing, developing, and using existing services for software building.
- Dynamic provisioning of computing, storage, networking, and IT infrastructure.
- Resources are offered on a pay-per-use basis via the internet.
- Cloud services are readily available to anyone with a credit card.
- Infrastructure can be rapidly deployed and scaled according to demand.
- The chapter explores Cloud computing's vision, features, technological developments, and insights into its environments.
Cloud Computing at a Glance
- In 1969, Leonard Kleinrock envisioned "computer utilities" serving homes and offices nationally.
- This vision anticipated today's Cloud computing model.
- Cloud computing services are readily available on demand, much like water, electricity, telephone, and gas.
Mastering Cloud Computing
- Consumers don't need complex IT infrastructure to access services.
- Services are accessed based on requirements without location restrictions.
- Cloud computing leverages virtualization for resource consolidation.
- Cloud computing offers pay-per-use access to compute, storage, and services.
- Cloud computing provides flexible and dynamic IT resources.
- Cloud computing can be used to integrate additional capacity and features into existing systems.
- There's a growing trend in standardizing and consolidating underlying technologies that support cloud systems.
The Vision of Cloud Computing
- Cloud computing allows users to provision virtual hardware, runtime environments, and services.
- Subscription-based access is available without upfront commitments.
- Services are used on demand, and maintenance is minimal.
- A collection of utilities can be put together in hours, not days, for application deployment.
A Closer Look
- Cloud computing impacts various sectors like enterprises, governments, and research organizations.
- Enterprises can offload tasks to Cloud-based systems, like converting archives.
- Startups and small businesses can quickly turn ideas into functioning services using minimal upfront capital.
- System developers can manage tasks and focus on business logic instead of complex infrastructure handling.
- End users benefit from accessing documents from anywhere via any device.
Defining a Cloud
- Cloud computing is a popular term for various aspects (technologies, services, concepts).
- Often associated with virtualized infrastructure, IT outsourcing, and software as a service.
- The diagram displays major concepts in Cloud computing (Fig. 1.2).
Cloud-Computing Reference Model
- Cloud computing allows varied services, categorized as IaaS, PaaS, and SaaS.
- There are layers from infrastructure (hardware) to application (software).
- This model helps understand the wide variety of services and underlying technologies in a layered approach (Fig. 1.5).
Building Cloud Computing Environments
- Development of Cloud-based applications and systems involves creating frameworks and platforms that support Cloud solutions.
- Web-based applications are particularly well-suited for cloud-based development due to their responsiveness to dynamically changing user demand.
- Resource-intensive applications also benefit from the scalability and dynamism of cloud computing.
- Cloud computing makes it simple to scale up or down computing resources, storage, and networking.
Cloud Computing Platforms and Technologies
- Large organizations are benefiting from replicating Cloud service delivery models in-house.
- This approach leads to more efficient and secure use of computing facilities.
- Cloud computing models are applicable to various business and institutional domains.
- Examples include Amazon Web Services (AWS), Google App Engine, and Microsoft Azure.
Distributed Systems
- Cloud computing facilities provide services to third parties, as a single coherent system.
- The architecture includes mainframes, clusters, and grids, each contributing to Cloud's eventual expansion.
- Mainframes: Early powerful, reliable computers for bulk data processing (e.g., bank transactions).
- Clusters: Cheap commodity computers connected by high-speed networks for scalable computing.
- Grids: A dynamic network of heterogeneous computing nodes, scaling beyond the power of a single cluster.
Utility-Oriented Computing
- Computing resources are offered on a pay-per-use basis and available as utilities.
- The idea of "utility computing" was well-known before and underlies many of today's cloud computing offerings.
- Early examples include mainframe providers offering computing resources.
- Computing grids expanded the idea of a wider range of resource access with standardized interfaces.
Review Questions
- The questions are designed to test understanding of concepts related to cloud computing.
