3. Cloud Computing Fundamentals

4. What is Cloud?
 The cloud symbol was used to represent networks of computing
equipment in the original ARPANET by as early as 1977,and the CSNET by
1981.
 a metaphor for the internet.
 cluster of objects that visually appear from a distance as a cloud.
 The cloud is actually a bunch of computer servers that store and transmit
data over the Internet.

5. Cloud Computing
 Cloud Computing is the transformation of computer
hardware, software and networks into a Utility just like the
your Electric Company, Water Company, or Gas Company.
 Delivered on demand, as service.
 For you:
 Does computing tasks, and/or
 Runs applications, and/or
 Stores Data
 Needs an Internet connection and access rights.

7. Cloud Models
• Public Cloud
• Private Cloud
• Hybrid Cloud
Deployment
Models
• Infrastructure as a Service (IaaS)
• Platform as a Service (PaaS)
• Software as a Service (SaaS)
Service
Models (SPI)

8. Deployment Model (Public Cloud)
 Service providers use the internet to make resources, such as applications
(also known as Software-as-a-service) and storage, available to the general
public. Their infrastructure is owned and operated by service provider.

9. Deployment Model (Private Cloud)
 Private clouds, deliver IT resources from within the corporate firewall.
Private clouds limit the number of users who have access to applications or
data.
 The goal of a private cloud is not sell “as-a-service” offerings to external
customers but instead to gain the benefits of cloud architecture without
giving up the control of maintaining your own data center.
 Security and privacy, more control, cost effective, and reliable.

10. Deployment Model (Hybrid Cloud)
 By using a Hybrid approach, companies can maintain control of an
internally managed private cloud while relying on the public cloud as
needed. For instance during peak periods individual applications, or
portions of applications can be migrated to the Public Cloud.
 Organizations can use private clouds for sensitive application, while public
clouds for non-sensitive applications.

11. Service Models
IaaS
• Service providers offer
computer, storage and
network component
such as firewalls in the
form of services.
Amazon Web Services (AWS), Cisco
Metapod, Microsoft Azure, Google
Compute Engine
PaaS
• Service provider
provides set of software
and tools hosted on
providers infrastructure.
Developers can develop
and deploy software
solutions on the
platform.
Amazon Web Services (AWS),
Microsoft Azure, Google App Engine
SaaS
• SaaS is a software
distribution model in
which applications are
hosted by service
provider and made
available to customers
over Internet.
Email Services, Google Docs, Microsoft
Office365

12. Which model?

13. Basic Difference
Feature IaaS PaaS SaaS
What you get? You get the infrastructure &
pay accordingly. Freedom
to use or install any OS,
software or composition
Here you get what you
demand. Software,
hardware, OS, web
environment. You get the
platform to use & pay
accordingly
Here you don’t have to
worry about anything. A
pre-installed, pre-
configured package as per
your requirement is given
and you only need to pay
accordingly.
Importance The basic layer of
Computing
Top of IaaS It is like a Complete
package of services
Technical Difficulties Technical knowledge
required
You get the Basic setup but
still the knowledge of
subject is required.
No need to worry about
technicalities. The SaaS
provider company handles
everything.
Deals with Virtual Machines, Storage
(Hard Disks), Servers,
Network, Load Balancers etc
Runtimes (like java
runtimes), Databases (like
mySql, Oracle), Web Servers
(tomcat etc)
Applications like email
(Gmail, Yahoo mail etc),
Social Networking sites
(Facebook etc)

 Microsoft Azure is a cloud computing service created by Microsoft for
building, deploying, and managing applications and services through a
global network of Microsoft-managed data centers

19. Azure Footprints

20. Windows Azure Storage

21. Introduction
 Cloud Storage - Anywhere and anytime access
 Blobs, Tables, Queues and Files
 Highly Durable, Available and Massively Scalable
 Easily build “Internet scale” applications
 Pay only for what you use
 Supports standard network protocols (HTTP, HTTPS etc)
 Rich Client Libraries and Tools
 SDKs available in multiple language (.Net, C++, Java, Python, etc)
 Supports all major Operating System.
 Supports microcontroller based IoT devices.

23. Storage Objects
 Blob (Binary Large Object)
 Provide a simple interface for storing named files along with
metadata for the file
 Tables
 Provide lightly structured storage with a set of entities that
contain a set of properties
 Queues
 Provide reliable storage and delivery of messages
 Files
 Supports text file storage
 Can create folders

24. Durability Options
 Locally Redundant Storage (LRS)
 Stores 3 replicas of the data within a single zone (facility) in a single region
 Provides data durability for disk, node and rack failures
 Geo Redundant Storage (GRS)
 Stores 6 replicas of the data across two regions (3 in each region)
 Provides additional durability to protect data against major regional natural disasters
(e.g., tornado, hurricane, fire, etc, destroying a whole region)
 Updates across regions are performed asynchronously
 Zone Redundant Storage (ZRS)
 Stores 3 replicas of the data across multiple zones (facilities) within a single
region or across regions
 Provides additional durability to protect data against zone failures (e.g., fire
burning down a facility)

25. Blob Containers
 Storage account
 An account can have many containers
 Container
 A container is a set of blobs
 Sharing policies are set at the container level
 Public READ or Private
 Associate metadata with blob container
 Metadata is <name, value> pairs
 Up to 8KB per container

26. Blob Storage Concepts

27. Table Data Model
 Table
 A storage account can create many tables
 .NET classes and LINQ
 A table is a set of entities (rows)
 An entity is a set of properties (columns)
 Two “key” properties that together are the unique ID of the entity in the
table
 Partition Key – In Table Storage, you have to decide on the PartitionKey
yourself.
 Row Key – uniquely identifies the entity within the partition.

28. Table Storage Concepts

29. Windows Azure Queues
 Provide reliable message delivery
 Simple, asynchronous work dispatch
 Programming semantics ensure that a message can be processed at least once
 Queues are highly available, durable and performance efficient
 Maximum size is 64K
 FIFO in general, but not guaranteed
 Pulling an item from the queue doesn’t delete it
 It becomes invisible for a visibility timeout
 Item must be deleted before timeout or else it becomes visible

31. Windows Azure Files
 Azure File storage is a service that offers file shares in the cloud using the
standard Server Message Block (SMB) Protocol.
 Since a File storage share is a standard SMB file share, applications running
in Azure can access data in the share via file system I/O APIs.
 Create/Delete/Resize Shares
 Create/Delete Directories
 Create/Read/Update/Delete Files

32. File Storage Concepts

33. Azure Management Portal

43. Conclusion
 Cloud computing enables pay-as-you-go cost model. Thus reduces overall
cost.

rely on durability, availability, and scalability
 Azure Storage is accessible from anywhere in the world, from any type of
application, whether it's running in the cloud, on the desktop, on an on-
premises server, or on a mobile or tablet device
