HP Also Having Their Own Cloud. They Are Having Their Own Cloud And They Are Providing Affiliate Cloud To Their Clients.

Intel, Microsoft, HP Almost Every Big Has Their Own Cloud.

1. Flexibility – So Cloud Computing Is The Best For Businesses Everybody Knows, We Have Number Of Benefits, So We Are Using The Regular Changes In The Your Resources Requirement Or Fluctuating  Benefit Of Demand.

So Sometimes You Need Less Number Of Resources, Sometimes You Need Large Number Of Resources And Actually You See, Your Demand Is Fluctuating.

And This Way In Physical Environment You Normally Purchase Your HardWare In Order To Just Manage Those Fluctuations And According To This Resources Can Be Scaled Up And Scale Down In Cloud Computing.

And To Scale Down And To Scale Up To Meet The Requirements Its The Method Of Few Seconds Or Minutes With Cloud Administrative Knowledge.

In Addition, AWS Enables You To Select Resources Of Your Choice, For Example Operating System, You Can Choose Any Operating System, You Can Choose Any Programming Languages Which Are Popular On Cloud Platforms These Days, You Can Choose Any Sort Of Data Base Which Requires Your Project, Web Application Platform And Other Services If You Require.

So It’s Really Flexible, There Is No Such Restriction, Nobody Is Forcing You To Just Work On Some Limited Set Of Resources.It’s Your Call.

So It’s Really Flexible, And You Can Scale Up And Scale Down, To Meet The Requirements.

Means, Autoscaling Is There.

2. Controlled Capital-Expenditure – You Can Say Reduced And Controlled Capital-Expenditure, Its Really Good Advantage.

So Think About Your Old And Traditional Way To Run IT Services, You Require The Servers, Storages, Routers, Cables, Connectors, Switches, Database Servers.

Number Of Things Are There In Your Traditional Environment.

Overall Cost Of Infrastructure Was Too High And To Cut Down The Cost Of Existing Physical Infrastructure, The Cloud Provides An Excellent Opportunity, You Can Now Choose AWS Services, Which Simply Based On ” Pay As You Go Model ”  And You Enjoy The Service Model.

So Instead Of Heavy Investment On Hardware And Software, Cloud Computing Provides Resources On Cloud.

You Can Configure Them As Per Your Need To Deliver Certain Services To Your End Users.

And This Way You Can Control, The Cost Of Your Infrastructure If It Is Not Require.

If It Is Require You Can Increase Your Resources.

So This Way It Is Directly Connected To Investment And Your Running Cost.

Software Updates – If You Have Some Idea About System Administration In Your Physical Environment, This Is Very TDS Job.Because Once You Are Running Your Machines And Sometimes You Need To Upgrade Your Softwares Or Operating Systems.

In All Servers In All Running Servers. You Normally Required A Dedicated Person And Dedicated Servers To Push Those Updates.

AWS Is Now Offer Patch Management Capabilities, We Have Patch Management Capabilities, Which Is Known As System Manage.

Which Is The Part Of Your EC2, EC2 Basically Is Service Is AWS, Which Is Being Used To Create Virtual Machines.

So, EC2 Means Elastic Compute Cloud Which Is Being Used To Create Virtual Machines, So The Patch Management Is Very Easy In AWS,

So With The Patch Management Capabilities, You Can Automate Your Patching Process, So This Feature Saves Your Time As well As Reduces The Cost Of  Your Running Infrastructure And Reduces The Risk Of the Non-Compliance Tool.

So Time To Time, Supplier Of Softwares, Like Microsoft Or Red Hat Or Any Another Vendor Who Is Providing Operating System Or Language They Are Providing.They Find Some Vernarabilities, Time To Time.

Which Can Be Cause Of Security Threat And To Fix Them, An Software Update Is An Essential Part, So Which Is Available Free Of Cost On  AWS.

So We Have A Service Called System Manager So You Need To Understand How To Manage It And How To Run It.

You Can Organize-It, You Can Simple Update The Running Application And Software Servers On AWS.

Stop Guessing Capacity – Stop Guessing Capacity Means Its Is Feature And Its A Benefit Of Cloud Computing. So When You Decide To Run An Application Over The Cloud, You Design An Infrastructure As Per Need.

And At The Time Of Designing, You Either End Up Sitting On Expensive Resources Or Dealing Limited Capacity.

But If You Are Working On Cloud Computing, You Don’t See Challenge Because The Cloud Computing Allows You To Tune The Infrastructure As Per The Requirement.

And You Can Define Minimum And Maximum, Capacity Of Resources, Which Can Scale Up Or Scale Down In Few Minutes.

Example – Let’s Say You Have One Application, You Hosted That Application One AWS Server, Later On, You Feel That One Server Is Not Sufficient To Bear The Load.

So Anytime You Can Increase The Number Of Servers And For That You Have Not Inform Anybody & You Have Not To Purchase Infrastructure In Advance As We Normally Purchase In Your Physical Environment.

So Anytime You Can Increase Number Of Resources And Anytime You Can Decrease Any Number Of Resources And You Are Paying Only For The Used Resources To AWS.

This Is The Good Thing.

You Have Not To Worry About The Liencencing Of Operating System You Are Using On Those Machines.

You Are Only Paying For The Resources On Hourly Basis.

This Is A Good Thing.

So Thats Why This Is Very Big Advantage And Relief For IT Managers And Infrastructure.
