Welcome to the world of
Cloud Computing
![Page 3: Mahika cloud services](https://reader036.vdocuments.site/reader036/viewer/2022081605/587ff3f11a28ab3a1e8b4a8f/html5/thumbnails/3.jpg)
What is cloud computing?• Cloud computing is a comprehensive solution that delivers IT
as a service. • Computers in the cloud are configured to work together and
the various applications use the collective computing power as if they are running on a single system.
• The flexibility of cloud computing is a function of the allocation of resources on demand.
• Resources are used as an aggregated virtual computer• Cloud configuration provides an environment where
applications execute independently without regard for any particular configuration.

Cloud computing - Definition
Cloud computing is a new style of computing where IT infrastructure is available as a ubiquitous, easily accessible, and reliable utility service conceptually similar to the telephone or electricity.

Why cloud computing?
• The main advantage of using cloud computing facility is that customers do not have to pay for infrastructure installation and maintenance cost.
• As a user of cloud computing you have to pay the service charges according to your usage of computing power and other networking resources.
• No need to worry about software updates, installation, email servers, anti-viruses, backups, web servers and both physical and logical security of your data.

Three Cloud Service ModelsSoftware as a Service ‘SaaS’
SaaS features a complete application offered as a service on demand. A single instance of the software runs on the cloud and services multiple end users or client organizations.
![Page 15: Mahika cloud services](https://reader036.vdocuments.site/reader036/viewer/2022081605/587ff3f11a28ab3a1e8b4a8f/html5/thumbnails/15.jpg)
Three Cloud Service ModelsPlatform as a Service ‘PaaS’
Platform as a service encapsulates a layer of software and provides it as a service that can be used to build higher-level services.Someone producing PaaS might produce a platform by integrating an OS, middleware, application software, and even a development environment that is then provided to a customer as a service
![Page 16: Mahika cloud services](https://reader036.vdocuments.site/reader036/viewer/2022081605/587ff3f11a28ab3a1e8b4a8f/html5/thumbnails/16.jpg)
Three Cloud Service ModelsInfrastructure as a Service ‘IaaS’
Infrastructure as a service delivers basic storage and compute capabilities as standardized services over the network. Servers, storage systems, switches, routers, and other systems are pooled and made available to handle workloads that range from application components to high-performance computing applications.

Two Technologies for Agility
• Virtualization:The ability to run multiple operating systems on a single physical system and share the underlying hardware resources*
• Cloud Computing:“The provisioning of services in a timely (near on instant), on-demand manner, to allow the scaling up and down of resources”**
* VMware white paper, Virtualization Overview
** Alan Williamson, quoted in Cloud BootCamp March 2009

Changing IT Job Oppurtunities
High pressure on Businesses to create new Value Adds continuously to survive competition
High pressure on Delivery and Technology teams to reduce investment without impacting the service delivery quality
Natural choice is Cloud Computing platform
IT professional must have end-to-end IT Management skills, no more domain specific knowledge at entry level
Virtualization skills is mandatory now for every IT professional
Even Networking Engineers must know Virtualization because they have to now manage “Virtual switches”

Cloud careers & Roles
• The Cloud Developer• The cloud developer will need to understand how applications
are designed, developed, and deployed for a PaaS. The skills developers need to invest in to prepare for the cloud include the following:
• Identity management • Windows Communication Foundation (WCF)and Rich Internet
Application (RIA) services • Connects• Middleware • Architecting Cloud Solutions

Cloud careers & Roles
• Database Administrator Opportunities• Database administrators (DBAs) who are able to design and
manage databases anywhere also emerge as an important role. DBAs in a cloud environment need to invest in skills like architecting a cloud strategy (e.g., story type, cost) and identifying potential data to move to cloud storage (Windows Azure, SQL Azure). To take advantage of the scaling nature of the cloud, DBAs need to be aware of the new storage services. Windows Azure storage services provide scalable blob, queue, and table storage services, and SQL Azure provides a cloud-based relational database service built on Microsoft® SQL Server® technologies
