Cloud computing: definition

“Cloud computing has the potential to create irreversible changes in how computers are used around the world”

7

Cloud computing: definition

“Cloud computing technology’s objective is to move any application stored on a computer to a remote location, eliminating all the standard components, including operating systems and hard drives, which are necessary in today’s computers and make them accessible online through a standard browser.”

Cloud computing providers

So..? Leave it to the experts.

… who have a lot of money to spend to build large datacenters in different locations of the globe.

Benefits/Challenges

25

Reduce IT infrastructure on the organizations side

Reduce the maintenance of datacenter

Reduce the costs

Energy, air condition

Licenses

Access applications and data “anytime, anywhere”

x Ensure privacy and confidentiality

x Interoperability with existents protocols

x Portability

Services

26

27

What fits in the cloud services?

Elastic capacity: applications to scale

SOA applications: all of them use mainly web services to communicate

Access anytime and anywhere

High parallelized workflows

28

Cloud computing stack

Software as a service(Finished application: for sales and it

customizable)

Plataform as a service(Developer plataform that abstracts the

infrastructure OS)

Infrastructure as a service(Abstract real infrastructure)

29

Infrastructure-as-a-Service

Adding “servers” in a click

Run it in just a few minutes, not days

30

Infrastructure-as-a-Service

Create Virtual Machines on demand

Snapshots

Start/Stop machines

Automatically scale

Pay only the resources that the machine are using

There is an API, you can management the infrastructure programming or invoking web services

31

Infrastructure-as-a-Service - Hybrid

32

High Level: Platform-as-a-Service

Platform-as-a-Service (PaaS) Storage-as-a-Service Database-as-a-Service Notification-as-a-Service

33

Storage-as-a-Service

Blobstore: upload blobs/data objects to the cloud

Based on Key, Value concept

Each blobstore can contain several containers/buckets.

They have a Key and the value is a binary blob. The developer can store information

34

Storage-as-a-Service

Providers: Dropbox API S3 Google Storage Azure Storage Box.net Rackspace Store

35

Databases – Columnar Data

Flexible and mutable tables

Key/Value structure

Providers: Datastore Google AppEngine Azure Table SimpleDB – AWS

36

Notification systems

Asynchronous message queue

HTTP protocol

Publish/Subscribe pattern

Examples: Channel API PubNub

Frameworks/SDKs

37

Google AppEngine: What is it?

Platform-as-a-Service

Languages: Java and Python

Create Web Applications

Free (to start with)

www.appspot.com

39

Google AppEngine: services

40

Google AppEngine: Dashboard

41

Google AppEngine: Dashboard

42

Google AppEngine: Datastore

“Bigtable is a distributed storage system for managing structured data that is designed to scale to a very large size: petabytes of data across thousands of commodity servers. Many projects at Google store data in Bigtable, including web indexing, Google Earth, and Google Finance”

43

Requires a new way of thinking

44

Google AppEngine: Channel API

Channel API: notification and collaborative environment

45

PubNub

Free service to do notification in real time

Accessible via Web Services

Easy to use for collaborative systems

Check it out: http://www.pubnub.com/console

Free alternatives to deploy locally: http://www.ape-project.org/ XMPP/Smack

46

PubNub

47

Multi cloud frameworks

Jclouds: Multi cloud library

Services: Computing Service Blobstore service

Language: Java

Supports several cloud providers for Computing Utility and Storage

Jclouds.org/github

49

Jclouds - blobstore

BlobStoreContext context = new BlobStoreContextFactory().createContext("aws-s3", identity, credential);

BlobMap map = context.createBlobMap(”food");

Blob blob = map.blobBuilder("sushi.jpg")

.payload(new File("sushi.jpg"))// or byte[]. InputStream, etc.

.contentDisposition("attachment; filename=sushi.jpg")

.contentType("image/jpeg")

.calculateMD5().build();

map.put(blob.getName(), blob);

context.close();

50

Other services

Computing services: launch machines on demand. Allocate processing and memory Grow dynamically Pay what you use

Networking

Payments

Workflow

… and many others.

51

What to do next?

Keywords: Google AppEngine, AWS S3, Dropbox API, Cloud API

Google AppEngine – SDK (PaaS)

Dropbox API – Storage

Google API – Services

Install your own services (testing)
