Cloud computing provides on-demand access to shared computing resources like servers, storage, databases, networking, software and analytics over the internet. It has several key characteristics including on-demand self-service, broad network access, resource pooling, rapid elasticity and measured service. Migrating to the cloud involves transferring business processes, applications and data from on-premise systems to cloud platforms and optimizing them to take advantage of cloud features through a seven step model.

2. • Cloud computing basics
• History of cloud computing
• Importance of cloud computing in the current era
• Characteristics of cloud computing
• What cloud computing really is

3. Cloud Computing is the
delivery of computing
services such as servers,
storage, databases,
networking, software,
analytics, intelligence,
and more, over the
Cloud (Internet).

5. • Cloud computing is a model for enabling convenient, on-
demand network access to a shared pool of configurable
computing resources (e.g., networks, servers, storage,
applications, and services) [Mell_2009], [Berkely_2009].
• It can be rapidly provisioned and released with minimal
management effort.
• It provides high level abstraction of computation and
storage model.
• It has some essential characteristics, service models,
and deployment models.

7. • Cloud Computing provides an alternative to the on-premises
datacentre.
• With an on-premises datacentre, we have to manage
everything, such as purchasing and installing hardware,
virtualization, installing the operating system, and any other
required applications, setting up the network, configuring the
firewall, and setting up storage for data.
• After doing all the set-up, we become responsible for
maintaining it through its entire lifecycle.
• But if we choose Cloud Computing, a cloud vendor is
responsible for the hardware purchase and maintenance.
• They also provide a wide variety of software and platform as
a service. We can take any required services on rent.
• The cloud computing services will be charged based on
usage.
•

14. • There are basically 5 essential characteristics of Cloud
Computing.
• On-demand self-services:
The Cloud computing services does not require any
human administrators, user themselves are able to
provision, monitor and manage computing resources as
needed.
• Broad network access:
The Computing services are generally provided over
standard networks and heterogeneous devices.

15. • Rapid elasticity:
The Computing services should have IT resources that are able to
scale out and in quickly and on as needed basis. Whenever the user
require services it is provided to him and it is scale out as soon as its
requirement gets over.
• Resource pooling:
The IT resource (e.g., networks, servers, storage, applications, and
services) present are shared across multiple applications and
occupant in an uncommitted manner. Multiple clients are provided
service from a same physical resource.
• Measured service:
The resource utilization is tracked for each application and occupant,
it will provide both the user and the resource provider with an
account of what has been used. This is done for various reasons like
monitoring billing and effective use of resource.

16. • Biggest benefit is storage

17. • Not a data centre
• Not a client server computing
• Not a grid computing
• Not a centralized system

18. • Pros and cons of Cloud computing
• Nature of the cloud
• Technologies in cloud computing
• Migrating into the cloud
• Seven step model

20. Pros Cons
Lower operations costs Complex pricing structures
Massive scalability Potentially prohibitive fees
Rapid access to the latest hardware
and software
Can require specialized
skillsexperience
Faster connections between cloud
based services and to end users
Secure underlying infrastructure
More reliable and redundant than most
enterprise data centers

24. • What Is Cloud Migration?
• Cloud migration transfers digital business processes
and workflows to cloud platforms. This process
entails moving information, applications, processes,
and other digitized business components from an on-
premise or existing cloud database to a cloud-based
data center.

27. • It is an effort in understanding and leveraging the cloud
computing service offering in the enterprise context.
• The model is as follows
• 1.Conduct cloud migration assessments
• 2.Isolate the dependencies
• 3.Map the messaging & Environment
• 4.Re-architect & implement the lost functionalities
• 5.Leverage cloud functionalities & features
• 6. Test the migration
• 7. Iterate and optimize
