The advancement in technology has greatly influenced the business transactions. The adoption of digital technology has led to automation in the hospitality industry. Business in hospitality industry such as restaurants can be improved with the help of digital systems. The competition in restaurant business have increased with the advancements in food ordering techniques. This project aims to automate the food ordering and billing process in restaurant as well as to improve the dining experience of customers. Here we discuss about the design & implementation of Smart Restaurant ordering system with real time with customer’s feedback for restaurants. The system on user’s table will have all the details of his account as well as menu. The order details from the customer’s table are updated and subsequently sent to kitchen after swiping the RFID card from which the amount will be deducted. The restaurant owner can manage the menu modifications easily. Touch screen provides fast access to any and all types of digital media, with no text bound interface getting in the way. Faster input can mean better service. Touch screens are practical in automation which has become even simpler with advancement in technology.

1. Cloud Computing Terminology
Cloud
In cloud computing, "cloud" is used as a metaphor for the internet, so
the phrase cloud computing means a type of Internet-based computing.
Cloud services
Cloud services are applications, services or resources made available
to users on demand via the Internet, such as IaaS, PaaS, SaaS, and
data storage.
Clusters
A computer cluster is a collection of interconnected stand-alone
computers or servers that can work together as a single integrated
computing resource.
Containers
A container is a “wrapper” that allows software to travel between
operating environments. Containers create a unique virtual instance of
an operating system (OS) that separates an application from others in
the same environment. Containers can run separate instances of an
application within a single shared OS.
Hybrid cloud
A hybrid cloud is a combination of traditional IT and public or
private clouds (or both) that remain separate but are bound together
by technology that makes the data or application portable.
Infrastructure as a Service (IaaS)
IaaS delivers computer infrastructure on an outsourced basis to
support a company’s operations. It includes servers, network,
operating systems, and storage, through virtualization technology
which doesn’t require that the company physically maintain or manage
it. Its cloud servers typically include a dashboard or an API that
gives the company control of the entire infrastructure.
Startups and small companies may prefer IaaS to avoid spending time
and money buying and creating hardware and software such as servers,
storage, or networking resources.
Kubernetes
Kubernetes is an open-source platform for managing containerized
workloads and services.

2. Multi‐cloud
Multi-cloud is the use of more than one public cloud, a strategy that
allows enterprises to choose specific services from a combination of
public IaaS clouds such as IBM Cloud, Amazon Web Services, and
Microsoft Azure. This enables companies to avoid locking in to any one
cloud provider.
On premise versus off premise
On premise refers to a solution installed and hosted in-house. Private
cloud is hosted in a company's own data center.
A solution that is hosted on dedicated hardware that happens to be in
a different physical location is referred to as off premise.
Platform as a Service (PaaS)
Platform as a Service (PaaS) provides cloud components for software
programs. PaaS delivers a framework for developers that they can use
to create customized applications. The platform typically includes an
operating system, a programming language execution environment, a
database, and a web server.
When you hear PaaS, think of development tools, database management,
and business analytics.
Private cloud
A private cloud is an on premise or off premise cloud infrastructure
operated solely for one organization. It may be managed by the
organization or by a third party.
Public cloud
A public cloud is available to the general public or a large industry,
owned and managed by an organization selling cloud services.
Software as a Service (SaaS)
SaaS refers to a model of software deployment where online software is
provided as a service to customers.
When you hear SaaS, think of hosted subscription applications or web
email, Google apps, or Dropbox.
Virtualization
Virtualization is the creation of a virtual (rather than actual)
version of something such as a server, a desktop, a storage device, an
operating system, or network resources.

3. Virtual machine
A virtual machine (VM) is a software program or operating system that
behaves like a separate computer that can run applications and
programs.
Workload
A workload is a discrete capability or amount of work to be run in the
cloud, such as serving up a Web site.
