- 3. Cloud Computing "cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.“ National Institute of Standards and Technology's (NIST)
- 4. Characteristics of Cloud Computing Agility – rapidly and inexpensively re-provision technological infrastructure resources. APIs – accessibility to software that enables machines to interact with cloud software. Cost – reduction in cost. Device and location independence – enable users to access systems using a web browser regardless of their location. Multi-tenancy – enables sharing of resources and costs across a large pool of users. Reliability – is improved. Scalability – via dynamic (“on-demand”) provisioning of resources. Security – could improve due to centralization of data, increased security-focused resources. Maintenance – of cloud computing applications is easier, since they don’t have to be installed on each user’s computer. Metering – means that cloud computing resources usage should be measurable and should be metered per client and application on a daily, weekly, monthly, and yearly basis.
- 7. Infrastructure as a Service (IaaS) The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components.
- 8. Platform as a Service (PaaS) The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages, libraries, services, and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment.
- 9. Software as a Service (SaaS) The capability provided to the consumer is to use the provider’s applications running on a cloud infrastructure. The applications are accessible from various client devices through either a thin client interface, such as a web browser (e.g., web-based email), or a program interface. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
- 10. Cloud Computing Deployment Models Cloud – A cloud-based application is fully deployed in the cloud and all parts of the application run in the cloud. Hybrid – A hybrid deployment is a way to connect infrastructure and applications between cloud-based resources and existing resources that are not located in the cloud. On-premises – The deployment of resources on-premises, using virtualization and resource management tools.

- 13. AWS Global Infrastructure The AWS Cloud infrastructure is built around AWS Regions and Availability Zones 25 AWS Region – is a physical location in the world where we have multiple Availability Zones 80 Availability Zones – consist of one or more discrete data-centers, each with redundant power, networking, and connectivity, housed in separate facilities

- 44. Amazon S3 Amazon Simple Storage Service (Amazon S3) is an object storage service that offers industry-leading scalability, data availability, security, and performance. This means customers of all sizes and industries can use it to store and protect any amount of data for a range of use cases, such as data lakes, websites, mobile applications, backup and restore, archive, enterprise applications, IoT devices, and big data analytics. Amazon S3 provides easy-to-use management features so you can organize your data and configure finely-tuned access controls to meet your specific business, organizational, and compliance requirements. Amazon S3 is designed for 99.999999999% (11 9's) of durability, and stores data for millions of applications for companies all around the world.
