Containers are lightweight and portable executable units (images) of software. They supply portability between different platforms and clouds. Containers are self-contained units that are designed to hold applications as well as all libraries and dependencies that the application requires. Containers can be run on physical computers or in the cloud.

Containers do not have an operating system of their own. Instead, they access the operating system of the device they are running on using a hypervisor. This allows them to be more light-weight, easier to provision, and much smaller than traditional virtual machines.

Virtual machine is a virtual re-presentation of physical computer, you can understand it as a computer inside a computer. Each individual virtual machine behaves exactly as though it were its own computer. It has its own operating system, memory, storage, and compute and is totally unaware of other virtual machines that could be running on the same host.

How do containers differ from a traditional VM?

Traditional virtualization leverages a hypervisor to virtualize physical hardware. Each VM contains:

- A guest operating system (OS)

- A virtual copy of the hardware that the OS requires to run

- An application and its associated libraries and dependencies

- Containers, on the other hand, virtualize the operating system. Each container only contains:

- The application

- Its libraries

- Its dependencies

IBM Cloud Paks are: Portable and can run anywhere: The portability of hybrid cloud solutions built with IBM Cloud Paks means that they are built to run on any hybrid cloud environment.

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).

IBM Cloud® Identity and Access Management (IAM) provides secure access control that enable developers to do all sorts of useful things. For example, if an organization’s corporate security policies require that IBM Cloud credentials always be encrypted and rotated every week, developers can use IAM to securely provide credentials that write to the Cloudant Service.

IAM policy enables a subject to access a resource. There are three primary values in a policy: a subject, roles, and resources.
