INTRODUCTIONThe cloud is something that you have been using for a long time now in the form of the Internet. Then, what is it that is creating this buzz about cloud computing. So here are the cloud computing features that make it the latest sensation promising to shape the entire future of modern computing. The cloud computing benefits are so immense that it is looked upon as a utility model of computing, with which an application can start small and grow to be enormous overnight. In 2008 Oracle CEO Larry Ellison said “The computer industry is the only industry that is more fashion-driven than women’s fashion.” to a group of Oracle analysts. So let’s talk about what cloud computing is and tighten up our definition and understanding of this implementation.

Cloud Computing refers to both the applications delivered as services over the Internet and the hardware and systems software in Internet infrastructure (called a platform).

Hide the complexity infrastructure by providing very simple graphical interface or API (Applications Programming Interface).

Provides on demand services, that are always on, anywhere, anytime and any place.

Pay for use and as needed, elastic. The hardware and software services are available

to the general public, enterprises, corporations and businesses markets.

What is Cloud Computing?

HISTORY The concept was coined by John McCarthy in

1960. The term cloud came into commercial use in

the early 1990s generally refers to large ATM network.

By the 21st century the real concept of “cloud computing” has appeared most focus was on SaaS.

In 1999 , Saleaforce.com was established by Marc, Parker and his fellows.

IBM extended the concept in 2001.

LAYERS OF CLOUD COMPUTING

CLOUD SOFTWARE AS A SERVICE (SAAS)

Software services are applications or components that can be used as an end application or used as part of a custom solution

Software Services include – Billing, Financials, Legal, Human Resources -

Aria Systems, OpSource Sales, CRM - Concur, Xero, Workday

Desktop Productivity - DirectLaw, Advologix

Content Management - Taleo, Workday

Backup & Recovery - Xactly, LucidEra, StreetSmarts

Document Management - Salesforce.com, NetSuite, LiveOps

Collaboration - Box.net, DropBox

Social Networks - Ning, Zembly

CLOUD PLATFORM AS A SERVICE (PAAS)

Platform services offer a ready built infrastructure and application frameworks that can be used for building and running applications.

Platform Services include - General Purpose - provide development tools for

cloud‐capable applications or application fragments.

Vendors - Force.com, LongJump, Google App Engine, MS Azure Services Platform

Business Intelligence - provide business intelligence capabilities as service and can be cloud‐based.

Vendors - Aster DB, Panaroma, Vertica

Integration - provide integration and process orchestration capabilities delivered as a service.

Vendors - Amazon SQS, HubSpan, Microsoft BizTalk Services

CLOUD INFRASTRUCTURE AS A SERVICE (IAAS)

Infrastructure services provide building blocks that can be moulded to run different application servers, packaged applications, etc., which can be used to host applications.

Infrastructure Services include - Storage - Provide metered, on‐demand storage of

structure or un‐structured data delivered as a service.

Vendors - Amazon EBS & S3, MossoCloud Files, Nirvanix, VaultscapeStorage Compute - provide metered, on‐demand execution of

codes, services or applications delivered as a service.

Vendors - Amazon EC2, MossoCloud Servers, AppNexus, Terremark, GridLayer Services Management - provide a layer of management of

the infrastructure services

Vendors - IBM, RightScale, Scalr, CloudStatus, Kaavo

CLOUD COMPUTING TYPES Hybrid cloud

Private cloud

Public cloud

Community cloud

CONTINUE….

Private Cloud - The cloud infrastructure is operated solely for an organization.

Community Cloud - Several organizations have similar requirements and seek to share the cloud infrastructure.

Public Cloud – Cloud computing through off-site third-party provider

Hybrid Cloud – Mix of Cloud models. Normally used for archiving and backup functions

CLOUD PROVIDES

ADVANTAGES OF CLOUD COMPUTING

Lower computer costs. Improved performance. Reduced software costs. Instant software updates. Improved document format compatibility. Unlimited storage capacity. ( pbytes !!!) Increased data reliability. Universal document access Easier group collaboration Device independence

DISADVANTAGES OF CLOUD COMPUTING

Requires a constant Internet connection. Features might be limited.

THE FUTURE TRENDS Many of the activities loosely grouped together under

cloud computing have already been happening and centralized computing activity is not a new phenomena.

Grid Computing was the last research-led centralized approach.

However there are concerns that the mainstream adoption of cloud computing could cause many problems for users.

Whether these worries are grounded or not has yet to be seen.

Many new open source systems appearing that you can install and run on your local cluster – should be able to run a variety of applications on these systems.

CONCLUSION Cloud Computing is the fastest growing part of IT

Tremendous benefits to customers of all sizes.

Cloud services are simpler to acquire and scale up or down.

Key opportunity for application and infrastructure vendors.

Public clouds work great for some but not all applications.

Private clouds offer many benefits for internal applications.

Public and private clouds can be used in combination.

Economic environment is accelerating adoption of cloud solutions
