Cloud Computing and its Implementation ELYSIUM TECHNOLOGIES PRIVATE LIMITED Madurai | Trichy | Coimbatore | Kollam | Cochin | Tirunelveli T. Udhaya Shankar, M.E., By T. Udhaya Shankar, M.E., SENIOR TECHNICAL EXECUTIVE, KOLLAM BRANCH

Introduction Cloud Computing makes computer infrastructure and services available "on-need" basis. Cloud Services include hard disk, development platform, database, computing power or complete software applications would be provided. End users need not to have large expenses to access them, as they go for “Pay Per Use” basis. For Example : “Owning a car, Rent a Car and Hire a Taxi.”

Why Cloud Computing???

Cloud Computing is an computing environment in which the user will use the preinstalled, preconfigured software, resources or Infrastructure. End users may choose their own preferable infrastructures, executing architectures, etc., Payment will be done based on the usage of the services. Why Cloud Computing??? Cont.,

Key Characteristics Simplicity Cost Effective Multi Client Support Self Automation Security Scalability

Virtualization

Types of Services Major Services –Software as a Service (SaaS) –Platform as a Service (PaaS) –Infrastructure as a Service (IaaS) Additional Services –Storage as a Service (STaaS) –Security as a Service (SeaaS) –Database as a Service (DBaas), Etc.,

Types of Cloud There are three types of cloud basically: They are –Public Cloud –Private Cloud –Hybrid Cloud

Public Cloud

This type of cloud is normally used in the hosting environment and their locations. Even though it is hosted the data are encrypted and stored securely. Here the resources and applications are added and removed dynamically based on the usage. It is cheaper and more useful for small and medium scale industries. Eg: Google Apps, Amazon Web Service

Private Cloud

The cloud is deployed with in a corporate firewall and runs on premise IT infrastructure. Private cloud is more expensive compared to the public cloud. The operating and bandwidth costs are to be maintained by the organization but this cloud is more secure than the public cloud. Private Cloud provides more benefits to the corporate by capitalizing on the Data Security and Corporate Governance.

Hybrid Cloud

Hybrid Cloud are increasingly being used by corporations where there is a need to maintain some of their applications. This type of environment where internal applications are deployed on private cloud. For normal usage while internet applications are deployed on the public cloud to handle variable loads.

Financial Feasibility Avoid capital expenditure Terminate Contract anytime. Lower Entry Cost Pay for only usage cost.

Privacy Encrypt data at rest Encrypt data in transit Strong Authentication Cryptography and more secure algorithms Manage access right holder

Applications Peer-to-peer / volunteer computing Web application On Demand Software as a Service Higher end, Middle end and small scale industries. Storage Security.

Implementation of Virtualization!! For Virtualization, I use VMWare Server. It is an virtualization tool through online supported by Tomcat Apache Server. Requirements: –VMWare Server –Internet Explorer –VMWare Plugin (Easily available in the Internet) –Operating System Image(.vmx format) –Pentium IV System with Password Enabled.
