Resource : A resource is an instance of a service like Cloudant, a Cloud Foundry application, Virtual Machine, Container. Resources are provisioned globally in an account scope. Resource Group : Resource group is a collection of resources like Virtual Machine, each resource group belongs to an account. all resources are created within a resource group. if a resource group is deleted then all the resources of that particular resource group also deleted. Region : Regions is a physical location with multiple availability zones, Regions are completely independent of each other, They're connected through a dedicated regional low-latency network. each region is located in separate geographic area. Zones : Zones are physically separate locations within each region, that are engineered to be isolated from failures. if we deploy application across two Availability Zones than It increases the availability of an application compared to running in a single Availability Zone. Datacenter : Within an availability zone, We can have multiple data centers. It can simply be a building where infrastructure is managed for a cloud.

Containers are packages of your software that include everything that it needs to run, including code, dependencies, libraries, binaries, and more. - Container-based applications are faster to load and start. - Container-based applications can easily create purpose-built microservices.

etcd is an open source distributed key-value store used to hold and manage the critical information that distributed systems need to keep running. etcd's performance is heavily dependent upon storage disk speed, so it's highly recommended to use SSDs in etcd environments. Redis (for REmote DIctionary Server) is an open-source, in-memory, NoSQL key-value store that is used primarily as an application cache or quick-response database. Redis supports multiple data structures, built-in Lua scripting, multiple levels of on-disk persistence, and high availability. Redis is an in-memory data store and can function as a database, cache, or message broker. In-Correct Answers : MongoDB is an open source, non-relational database management system that uses flexible documents to process and store various forms of data. A NoSQL solution, MongoDB provides an elastic data model that enables users to store and query multivariate data types with ease. This not only simplifies database management for developers but also creates a highly scalable environment for applications and services. MongoDB uses documents or collections of documents as its basic unit of data. Formatted as JSON objects, these documents can store various types of data and be distributed across multiple systems. MongoDB offers a few capabilities that make it stand out from other database management systems, including load balancing, ad hoc database queries, and multi-language support. PostgreSQL, commonly pronounced ''Post-GRES,'' is an open-source database that has a strong reputation for its reliability, flexibility, and support of open technical standards. PostgreSQL provides the ability to restore databases to a specific moment in time because it maintains a write-ahead log that logs every database change. PostgreSQL features built-in support for multiple procedural languages.

Correct Answers : The Essential Characteristics of Cloud Computing according to NIST : On-demand self-service : A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider. Broad network access : Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations). Resource pooling: The provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing, memory, and network bandwidth. Rapid elasticity: Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be appropriated in any quantity at any time. Measured service : Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service. Self diagnosis: It's self made option, added for distraction.

Multi Cloud is a combination of two or more cloud services from different cloud providers. In-Correct Answers : Private Cloud : The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises. Community Cloud : The cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be owned, managed, and operated by one or more of the organizations in the community, a third party, or some combination of them, and it may exist on or off premises. Public Cloud : The cloud infrastructure is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organization, or some combination of them. It exists on the premises of the cloud provider. Hybrid Cloud : The cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).
