DEFINITION OF CLOUD COMPUTING

DEFINITION OF CLOUD COMPUTING

DEFINING CLOUD � Wikipedia � � Gartner � � Cloud computing is Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on-demand, like a public utility. Style of computing in which scalable and elastic ITenabled capabilities are delivered as a service to external customers using Internet technologies Forrester � Standardized IT capability (services, software, or infrastructure) delivered via Internet technologies in a pay-per-use, self-service way.

NIST DEFINITION Cloud computing is a model for enabling Ubiquitous, Convenient, On-demand network access to a shared pool of configurable computing resources Networks Servers Storage that can be rapidly provisioned and released with minimal management effort or service provider interaction.

NIST DEFINITION Broad Network Access Rapid Elasticity Measured Service Resource Pooling On-Demand Self-Service

UBIQUITOUS NETWORK ACCESS � Ubiquitous network access means that the cloud provider’s capabilities are available over the network and can be accessed through standard mechanisms by both thick and thin clients.

RAPID ELASTICITY

RAPID ELASTICITY � Elasticity is defined as the ability to scale resources both up and down as needed. To the consumer, the cloud appears to be infinite, and the consumer can purchase as much or as little computing power as they need.

PUBLIC CLOUD (HOSTEL) Available to everyone. Anyone can go and signup for the service. Some public cloud concerns Ownership Control Regulatory compliance Data/Application security Liability for SLA breaches Public Cloud I n t e r n e t

PRIVATE CLOUD (HOME IN GANDHINAGAR) Cloud infrastructure built in house Retains control of resources More security & privacy Can conform to regulatory requirement Needs capital investment Needs expertise to build and maintain Private Cloud

HYBRID CLOUD (HOME IN A’BAD) Best of Both World Workload is deployed mostly on private cloud Resources can be used from public cloud when there is a surge in peak load (Cloud Burst) Public Cloud I n t e r n e t Private Cloud

NIST DEFINITION Iaa. S Public What is Service Models? Saa. S Private Community Hybrid

IAAS � Core Computing Resources � Servers � Storage � Network � Iaa. S - Infrastructure as a Service � Infrastructure Management is abstracted from users � Elastic and On-Demand � Pay per use

IAAS- USE CASES � 20 servers daytime during peak load, but only need 2 during normal load � 100 servers for 48 hours to do some load testing � 10 TB of storage to backup my data � Infrastructure to implement my disaster recovery mechanism

AMAZON – A MAJOR CLOUD PLAYER � Over a period of time Amazon has built A massively scalable & distributed system � Scale capacity on demand � Reliable infrastructure � Amazon has made this infrastructure available to public � � Known as AWS (Amazon Web Service)

AWS CLOUD SERVICE OFFERINGS Compute Messaging Database Networking Storage Payments & Billing Content Delivery E-Commerce Identity & Access Web Traffic Monitoring Workforce

FOR LINUX

PAAS � Software � Application Servers � Messaging � Notification � Paa. S Services - Platform as a Service � Platform for deployment and management of business applications � Management of infrastructure is abstracted � Load balancing, clustering, database management are also abstracted from users � Scales up or down automatically on demand

PAAS-USE CASES � Deploy web application on an infrastructure that can scale as demand grows � LAMP Stack � Ruby on Rails � Springs � Deploy Microsoft applications � No management overhead � Platform maintenance and operations � Database backup & Disaster Recovery � Scalability & Fault tolerance
