1.IntroductionThe company runs approximately 35 Linux server which perform the different kind oftasks like database hosting, file serving, email relay, application hosting, web hosting etc.Iaas (Infrastructure as a Service) is a structure of cloud computing the gives virtualizedcomputing in the internet. The service features of the three Iaas (Amazon Web Services(AWS), Microsoft Azure and Google Compute Engine) provider will be provided. Theoptions and services will be found for each Iaas provider to the IP address allocation andmanagement in virtual machines. The features and services will be identified to improve theprotect services from outages, undertake backups and client uptime. The virtual server will becreated, Installed and configured to run on Linux. The task will be done by using the free trialaccounts. The webpage will be created to contain the details such as subject name and otherdetails one can to choose. The web server operations will be tested using an external clientrequesting the web page that one have created2.Cloud services comparisonInfra structure as a service providers provide virtualized resources related to the cloudcomputing over the internet. Some of the IAAS are Amazon web services, Microsoft azure,Google. The comparison of services of these service providers are given below.Virtual Linux server hostingMicrosoft azure provides services likeCloud ServicesAzure Websites and AppsAzure BatchAzure SchedulerLogic Apps.These services appear to be standard services for azure. When comparing it with Amazonweb services, Amazon hosts different types of services like Amazon Elastic Beanstalk. Incomparison with azure and Amazon, Google’s web service is very standard though it hostslimited services but that has big data. The service hosted by Google includes Google AppEngine.Answer for question number 11

Each IaaSprovider has its own advantage with respect to storage. There are many types of storage that3
can be discussed. The types include object storage, block storage, hybrid cloud storage.Azure has a object storage that stores blobs, tables, queues and files that comes under thename called the azure storage. Amazon has s3 Amazon simple storage as the object storage.Google has the advanced object storage and that is named as the cloud storage. Next to cloudstorage, Block storage has its importance. Google has persistent storage when compared withazure and Amazon web services. Other type of storage option called the Hybrid cloud storagealso exists but not in google. Stor simple and AWS storage gateway are the hybrid storagespresent in Azure and Amazon respectively.IPv4 and IPv6 addressingAmazon web services support both IPv4 and IPv6 addressing in addition to separateaddressing, it also has the facility of dual addressing. The dual addressing is nothing but thecombination of both IPv4 and IPv6 addressing. A type of AWS namely Amazon Route 53supports both reverse and forward IPv6 addressing records.While investigating about Google, it is known that it can also have two types of addressingIPv4 and IPv6.If connect our instance over IPv4 addressing, address has to assigned tosucceed but while connecting our instance with IPv6 addressing, no need to assign address.Microsoft azure has a special feature of smooth transition from IPv4 to IPv6 addressing.Azure uses IPV6 widely and it has planned worldwide capability via IPv6 addressing.ReduntancyAmazon web services were found to be have durable redundancy. Microsoft Azure is foundto have locally redundant storage. Google is found to have geographically redundant storage.BackupAzure uses a backup technique called the azure backup. Amazon uses a backup techniquecalled the Amazon Glacier backup. Google uses Google Cloud Backup.3.Installation of the virtual Linux serverAnswer for question number 2To create and execute virtual machine in the cloud, the web service named asAmazon elastic compute cloud is used. These steps will helps to launch virtual machine on4
Amazon. The below mentioned steps are helps to launch the Linux virtual machineeffectively..Step 1: Launch an Amazon EC2Open Amazon EC2 console and click on Launch Instance (virtual machines are calledinstances). This is required to create and configure your own virtual machine.Step 2: Configuring Instancesa.In this screen, you will be shown an Amazon Machine Image (AMI), a templatecontaining software configuration (e.g. an operating system, an application server, andapplications). Launch an instance from AMI.b.Choose an appropriate mix of applications from combinations of CPU, memory,storage, and networking capacity to create an instance type. Covered by Free Tier, thisoffers enough compute capacity.c.Selected configuration, storage, tagging, and security settings can be reviewed.Accept default values or customize.d.Chose an existing key pair or create a new key pair. Save your key pair somewheresafe.e.See status of instance you just created on next screen.f.Also note Public IP address.Step 3: Connect to InstanceAfter all the creating instance process this is the time to connect to it.Step 4: TerminationTerminate your instance if you aren’t using them or you will be charged for something not inuse.Now register a domain name and attach it to a instance, allowing end users to find yourapplications.Below screenshot shows the creation of new Amazon Web service. To create a new accountlike by giving the AWS account name, email address and password.5
Below screenshots displays the login page for root user by giving the email id and password to eaccess the root user page.6
