IBM Cloud® Internet Services Edge functions allow you to create or modify existing applications,

without having to configure or maintain infrastructure, by using a serverless execution environment.

Edge functions run on CIS edge servers, not in the user’s browser. That means you can trust that your

code runs in a trusted environment where it cannot be bypassed by malicious clients. It also means

that the user does not need to be using a modern browser that supports service workers – you can

even intercept requests from API clients that aren't browsers. Edge Functions allows you to run code

closer to users of your public-facing applications or websites. In turn, you can improve your

application's performance and reduce latency. This means you can quickly create new applications or

modify existing ones without having to configure or maintain infrastructure via our serverless

execution environment. Once a new application is deployed or an existing application is modified, it

takes us ~15 seconds to get the changes distributed globally to our 180+ PoPs worldwide.

The Internet of Things, or IoT, refers to the billions of physical devices around the world that are now

connected to the internet, all collecting and sharing data.

Infrastructure-as-a-Service, commonly referred to as simply “IaaS,” is a form of cloud computing that

delivers fundamental compute, network, and storage resources to consumers on-demand, over the

internet, and on a pay-as-you-go basis. IaaS enables end users to scale and shrink resources on an as-

needed basis, reducing the need for high, up-front capital expenditures or unnecessary “owned”

infrastructure, especially in the case of “spiky” workloads. In contrast to PaaS and SaaS (even newer

computing models like containers and serverless), IaaS provides the lowest-level control of resources

in the cloud.

Analytics Engine service develop and deploy analytics applications using open source Apache Spark

and Apache Hadoop. Customize the cluster using your own analytics libraries and open source

packages. Integrate with IBM Watson Studio or third-party applications to submit jobs to the cluster.

HIPAA readiness option available in the Dallas region for Standard-Hourly and Standard-Monthly

plans.

VMware vSphere is a streamlined and optimized ordering platform for VMware. With this platform,

you can build your own IBM-hosted VMware environment by customizing and ordering the VMware-

compatible hardware based on your selected VMware components.

Hybrid cloud is simply the combination of public and private cloud environments working together to

run your applications or workloads. Key tenets of all hybrid clouds: interoperability, scalability,

portability, and security.

A VPC is a public cloud offering that lets an enterprise establish its own private cloud-like computing

environment on shared public cloud infrastructure. You can subdivide a VPC with subnets, where

each subnet can reach the public internet through an optional public gateway. You can assign an FIP

to any instance to reach it from the internet, or the other way around. This is independent of

whether the subnet is attached to a public gateway. Subnets within IBM Cloud VPC offer private

connectivity; they can talk to each other over a private link, through the implicit router. Setting up

routes isn't necessary.

IBM Cloud Site Reliability Engineers automate IT operations and improve system availability and

reliability. They can help clients build a modern network operations center.

Subnets are the foundational building blocks used to deploy cloud resources in your public cloud

VPC. They are bound to a single zone and cannot span multiple zones or regions, which helps with

security, reduces latency, and improves availability. Create multiple VPCs and subnets easily by using

the suggested prefix ranges and preconfigured network security policies or design and define your

own address prefixes and custom security policies. CIDR blocks 161.26/16 and 166.8/14 are both

reserved and routed into every subnet. Read about our service endpoints available for IBM Cloud

VPC. The default quota limit for the number of subnets that can be created within a VPC is 15.

Cloud native is an architectural style where the application is typically one that is designed to run on

a specific platform. In many cases, these applications can also be moved around to different cloud

platforms — so they are also cloud agnostic.

IBM Cloud® for VMware Solutions Shared uses VMware Cloud Director to enable you to extend your

VMs to the cloud with ultimate capacity and scalability, while paying only for what is consumed.

With IBM managing the infrastructure up to the hypervisor, you don’t need to worry about providing

updates and patching, and instead can focus on application innovation. IBM Cloud® for VMware

Solutions Shared is a Infrastructure collocation. Note: Infrastructure collocation is a rule that

discovers component instances that are installed in the same infrastructure and that are related to a

specific product in the software catalog.

IBM Cloud Developers are responsible for writing code to create and maintain cloud applications.

Hypervisor : a hypervisor is a lightweight software layer. A hypervisor is an abstraction layer that

abstracts physical compute resources, making them available virtually to virtual machines (VMs). The

hypervisor assigns processors, memory, and storage to each VM. It keeps VMs separate so that they

do not interfere with each other. Features of a hypervisor are: 1. A hypervisor is software that runs on

the physical server or host. 2. It pools the resources from the physical server and allocates them to a

virtual environment. 3. Hypervisors are leveraged to virtualize hardware whether it's on-premises or

in the public cloud.

DevOps is an approach to lean and agile software delivery that promotes closer collaboration

between lines of business, development and IT operations.

Correct Answer : True Software as a service (SaaS) is a service model, where you use the software

applications over the Internet provided by cloud provider, on demand and typically on a subscription

basis. With SaaS, cloud providers host and manage the software application and underlying

infrastructure, and they also handle any maintenance, such as software upgrades and security

patching. Examples : Gmail, Google DOC Organizations are using SaaS (Software-as-a-Service) to

avoid the need for ongoing upgrades, maintenance, and patching, in SaaS model, cloud provider

offer compete software as a service over the internet to users (Example- Google Doc, Gmail). In this

model, Software or Application are centrally hosted and delivered over the internet under licensed

on a subscription.

IBM Watson Assistant helps you construct chatbots and virtual assistants for a spread of channels

including mobile devices, messaging platforms, and even robots. IBM Watson Assistant allows you to

use the power of Watson to bring a conversational interface to your solution. Your customers can

interact with Watson Assistant using natural language conversation.

Watson Discovery unlocks hidden value in information to get answers, monitor trends, and repair

patterns with the world’s most advanced cloud-native insight engine.

Watson Discovery Service

enables you to ingest, normalize, enrich, index, search, and explore, your data, both structured and

unstructured. Watson Discovery gives you the ability to, store, analyze, and understand your data at

scale. First, Watson ingests and standardizes all of your data, no matter the type. Just load it and go.

Watson then enriches your data using natural language understanding capabilities.

Watson

Discovery allows you to interrogate your data in either a natural language format or a query

language that will search for both Boolean conditions and for phrases. Once the data is found,

Watson Discovery uses machine learning algorithms to order the answers so that the most useful

answers are listed first.

Watson Discovery leverages the power of Watson to add deep content

learning to your applications. One application of Watson Discovery is natural language

documentation search.

Content Delivery Network is a distributed server network that delivers temporarily stored, or cached,

copies of website content to users based on the users’ geographical location to enables faster web

performance. Exam tips: Remember CDN Improving website load times, by distributing content

from nearby CDN server.
