Identifying the Needsof

Cloud Computing

Defining Cloud

It is a broad topic, according to Gartner:

“Cloud is a style of computing where scalable and

elastic IT-related capabilities are provided as a service

to external customers using Internet technologies.”

6

Cloud Computing Attributes

Infrastructure and software could be provided as

services

Source: Gartner

Services can scale capacity up or down as the

consumer demands

Services share a pool of resources to build

economies of scale

Services are tracked with usage metrics to enable

multiple payment models

Services are delivered using Internet identifiers,

formats and protocols (IP, URLs, HTTP, REST,

etc),

Service Based

Scalable & Elastic

Shared

Metered by Use

Uses Internet Technology

Understanding Existing Applications

Understanding Existing Applications

Decompose applications into components:

12

Understanding Existing Applications

Application components could be deployed as services:

13

Understanding Existing Applications

Components could be scaled individually:

14

Concerns on Clustering

o Managing session affinity:o In memory distributed

o Persisted to a data store

o None distributed, load balancer centric

o Managing application state:o Distributed data structures

o Distributed caching

o Data replication for data storage

o Any other aspects that may get affected by distributed

computing

Identifying the Right Service Model

Cloud Computing Service Models

IaaS PaaS SaaS

Infrastructure as a Service:

- Provides computing,

storage and network

resources as a service.

Platform as a Service:

- Provides computing

platforms as s service on top

of an IaaS.

- The platforms Include

environments for deploying

applications.

Software as a Service:

- Provides software as a

service on top of a PaaS.

17

Identifying the Right Deployment Model

Cloud Computing Deployment Models

Private Hybrid Public

- Operated solely for a single

organization.

- Could host internally or

externally.

- Externally hosted: Virtual

Private

- Policy based and

coordinated service

provisioning across private

and public clouds.

- Services are rendered over

a public network.

- Managed by a third party

cloud provider.

Key Features in PaaS Cloud Providers

o Service & Application Lifecycle Management API

o Application Management Model (CAMP, CloudML,

TOSCA, etc)

o Standards based User Authentication/Authorization

o Multi-tenancy

o Policy based Autoscaling

o Scalable Dynamic Load Balancing

o Cloud Partitioning

o Cloud Bursting

o IaaS Independence (jclouds, etc)

o Linux Container (LXC) Management21

Key Features in PaaS Cloud Providers

o Configuration Management Tool Support o Ex: Chef, Puppet

o Monitoring Tools

o Billing

o Centralized Real Time Logging

WSO2 Private PaaS - Key Features

o Extensible cartridge architectureo Ability to plugin third party run-times such as PHP, MySQL, and

Tomcat

o Support for Puppet based cartridge creation for WSO2 Carbon

products

o Add multi-tenant or single tenant cartridges

o Enhanced cloud deploymento Support for multiple Infrastructure-as-a-Service (IaaS)o Fully tested on Amazon Web Services EC2o Experimental support for OpenStack and vCloudo Capability to support any IaaS via jClouds APIo Cloud-bursting to scale onto multiple IaaS’s at the same timeo High availability achieved through cloud burstingo Availability for private, public and hybrid cloud solutions

26

WSO2 Private PaaS - Key Features

o Multi-tenancy and self-provisioningo Manage a single set of servers with even better utilization

targets than that is achieved by virtualizationo Self-provision to manage and deploy a full middleware stack as

requiredo Simple click to add users and services, develop new

applications and manage an own setupo Shared cloud infrastructure such as server hardware, JVM,

database and services

o Tenant-aware elastic load balancero Highly tunable performance across different tenant requirements

o “Economy class” for low priority workloads

o “Private jet” mode for workloads that require dedicated resources

o Ability to accept both static and dynamic cluster domain registrations

27

WSO2 Private PaaS - Key Features

o Policy-based multifactor auto-scalingo Ability to automatically scale up or down depending on the loado Ability to transparently add services when new resources are

neededo Dynamic discovery enabling services to be automatically

detected when resource allocations change

o Easy SaaS App Developmento Built-in support for multi-tenant and single-tenant models

o Support for user identity management, metering and billing

o Provision of data storage with easy access, caching and queuing

o Provision of a SaaS app as a multi-tenant application and allows each

tenant to deploy their own customized logic alongside it

o Artifact Distribution Coordinator (ADC) with support for external Git

and GitHub repositories

o Ability to publish application logs into a centralized location for easy

monitoring28

WSO2 Private PaaS - Key Features

o Multiple options for interaction with the PaaSo Provides an interactive command line interface

o Provides an additional user friendly graphical user interface for user

friendliness
