In PaaS, users are ……

Software developers

Example of PaaS include …., …, …., and ….

Windows Azure, Force.com, Google App Engine, OpenShift

….. providers are cloud-based applications that users access on demand from the internet without needing to install or maintain the software

SaaS

Like …., ….. abstracts away the underlying infrastructure of the software application so that users are only exposed to the interface they interact with

PaaS, SaaS

Examples on SaaS include …, …, …, and …

GitHub, Google Docs, Dropbox, Slack

In SaaS, users are .....

End customers

In PaaS, you manage .... and ....

Applications, data

As cloud computing has ...... characteristic, an end user can provision computing capabilities, such as server time and network storage, eliminating the traditional need for IT administrators to provision and manage compute resources

Self-service provisioning

As cloud computing has ..... characteristic, companies can freely scale up as computing needs increase and scale down again as demands decrease

Elasticity

As cloud computing has ..... characteristic, compute resources are measured at a granular level, enabling users to pay only for the resources and workloads they use

Pey-per-use

As cloud computing has ..... characteristic, CSPs often implement redundant resources to ensure resilient storage and to keep users' important workloads running -- often across multiple global regions

Workload resilience

As cloud computing has .... characteristic, organizations can move certain workloads to or from the cloud -- or to different cloud platforms -- as desired or automatically for better cost savings or to use new services as they emerge

Migration flexibility

As cloud computing has .... characteristic, a user can access cloud data or upload data to the cloud from anywhere with an internet connection using any device

Broad network access

As cloud computing has .... characteristic, .... lets numerous customers share the same physical infrastructures or the same applications yet still retain privacy and security over their own data

Multi-tenancy, multi-tenancy

As cloud computing has .... characteristic, cloud providers service numerous customers from the same physical resources

Resource pooling

As cloud computing has ..... advantage, using cloud infrastructure can reduce capital costs, as organizations don't have to spend massive amounts of money buying and maintaining equipment

Cost management

As cloud computing has .... advantage, storing information in the cloud means that users can access it from anywhere with any device with just an internet connection

Data and Workload mobility

As cloud computing has .... advantage, all organizations worry about data loss. Storing data in the cloud guarantees that users can always access their data even if their devices are inoperable

Business Continuity and DisastervRecovery

As cloud computing has .... disadvantage, when relying on the cloud, organizations risk data breaches, hacking of APIs and interfaces, compromised credentials and authentication issues

Cloud security

.... is considered the greatest challenge facing cloud computing

Security

As cloud computing has .... disadvantage, cloud costs are frequently interdependent, with one cloud service often utilizing one or more other cloud services, all of which appear in the recurring monthly bill

Cost unlredictability

As cloud computing has .... disadvantage, With cloud-supporting technologies rapidly advancing, organizations are struggling to keep up with the growing demand for tools and employees with the proper skill sets and knowledge needed to architect, deploy, and manage workloads and data in a cloud

Lack of capability and expertise

As cloud computing has .... disadvantage, The emphasis on do-it-yourself capability in cloud computing can make IT governance difficult, as there is no control over provisioning, deprovisioning and management of infrastructure operations

IT governance

As cloud computing has .... disadvantage, every cloud is different, so multi-cloud deployments can disjoint efforts to address more general cloud computing challenges

Management of multiple clouds

As cloud computing has .... disadvantage, performance such as latency is largely beyond the control of the organization contracting cloud services with a provider

Cloud performance

As cloud computing has .... disadvantage, architecting, building and managing private clouds can be a daunting task for IT departments

Building a private cloud

As cloud computing has .... disadvantage, the process of moving applications and other data to a cloud infrastructure often causes complications

Cloud migration

As cloud computing has .... disadvantage, switching between cloud providers can cause significant issues

Vendor Lock-in

As cloud computing has .... disadvantage, this includes technical incompatibilities, legal and regulatory limitations and substantial costs incurredvfrom sizable data migrations

Vendor lock-in

A fundamental concept behind cloud computing is that the ..... of the service is irrelevant to the user
