The IBM Cloud Sales Engineer requires both sales and technical skills.
The IBM Cloud Security Engineer is focused on detecting risk and
keeping client and customer data safe.
The IBM Cloud Site Reliability Engineer can find root causes of
outages, understands system issues, and is good at anticipating a client’s
potential points of failure in their solution.
The IBM Cloud Solution Architect listens to client needs, understands
and solves client issues, and collaborates to design solutions using IBM Cloud
and other services.
Measured service is the cloud computing characteristic that describes consumers paying only for the services they use or reserve.
Cloud computing is any computing service provided by a third party, a model for enabling on-demand access to a shared pool of computing resources, a set of computing resources dedicated to an application with at least three years of growth headroom built-in, and a model for facilitating access to resources.
A hypervisor assigns processors, memory, and storage to virtual machines.
The earliest use of cloud computing occurred when companies sold unused time slices of computing in their mainframe systems.

In the 1950s is when the practice of providing shared access to a single
mainframe emerged.
A private cloud makes computing resources available to users over the
public internet.
On-demand self service, broad network access, resource pooling, rapid elasticity, and measured services are all essential characteristics of cloud
computing.
Allocates processors, memory, and storage to virtual machines are
functions of a hypervisor.
Virtualization enables the creation of multiple virtual computers on a
single physical host computer and each virtual guest has its own operating
system and applications.
Virtual machines can be relocated among physical computers in a
network so that they can be easily restarted on a different host in the event of a
physical server failure.
Vertically by adding more virtual CPU and memory to a particular
virtual machine or horizontally by creating more virtual machines through cloning
Container technology is an emerging trend in cloud computing focused
on hybrid multicloud as a result of historical events or natural disasters.
That's not correct. PaaS is a cloud service model that provides access to a platform where applications can be coded using software and tools within the cloud.
A private cloud model provides the greatest control and security because workloads are run behind an organization's firewall.
Three advantage of using a multicloud deployment instead of a hybrid cloud deployment include the ability to use the cloud services that best fit an organization’s workload (regardless of which supplier provides them), the ability to reduce an organization’s vulnerability to service outages (it is unlikely that both service supplies would experience widespread outages at the same time), and the ability to utilize the closest cloud region and cloud zone to the client to reduce network latency.
The modern cloud architecture focuses on supporting the portability of all of the workloads across all of the cloud environments and less on physical connectivity.
A private cloud deployment model could require all infrastructure
to be purchased and installed by the client.
Minimal investment is another advantage a company can have by
using the public cloud deployment model to deploy a new application.
Hybrid cloud allows an organization to take advantage of the security
and control of a private cloud while also realizing the financial benefits of using
the public cloud.
The public cloud deployment model has the lowest up-front
costs.
The Infrastructure as a Service provides on-demand access to
computing services, bare metal servers, networking, and storage.
Software as a Service takes care of all infrastructure and
application management.
Platform as a Service would allow a new company to code their
applications using software and tools hosted on IBM Cloud.
The benefit to a client who purchases Software as a Service is all
infrastructure and application management is handled by Software as a Service
vendor.
Companies choose to use the cloud to link long-established core systems with new front-end applications, to modernize development practices in core systems, and to improve quality and efficiency.
The IBM Cloud Hybrid approach facilitates leveraging strategic core
applications on legacy platforms while developing modern user-friendly
interfaces in containers.

The attributes of a hybrid cloud model include efficiency,
autonomy, and modernization.
