Overview XYZ is a medium scale company that makes use of 35 LINUX servers for the execution ofmany of the web hosting, application hosting, database hosting and other services. There are many service providers in the market that provide the services in this area whichare discussed in the report. Amazon is one of the market giants in this field that provides the services with the nameAWS EC2. It stands for Amazon Web Services Elastic Compute Cloud. This service makes iteasy for the web developers and resources to carry out web based cloud computing services.These services are also secure and reliable in nature. Some of the benefits that are offered byAWS EC2 include complete control and flexibility in terms of the cloud hosting services.These are low on cost and can also be easily integrated with the other services that areprovided by Amazon in the area of cloud computing and other technologies (Aws, 2017). The other name in the field that is extremely popular in the market is Microsoft and itprovides its cloud based services with the name of Microsoft Azure. It is an enterprise scalecloud computing platform that is open and flexible in nature. There are several services andsolutions that are provided by Microsoft Azure in the areas of digital marketing, e-commerce,mobile solutions, data warehousing, development and testing and many more. The powerfulfeatures along with the higher security and reliability have made this service providedpopular among the users. Internet of Things (IoT) related activities; backup and disasterrecovery can also be performed on this platform (Microsoft, 2017). Google also offers its IaaS cloud platform with the name of Google Computer Engine. It isflexible and high performance solution that makes it possible to carry out faster processingand operations with high level of user interaction. The services can be availed at low cost andthere is a huge customer base that is associated with this service provider. There are variousbenefits that are offered by Google Computer Engine in the form of batch processing,persistent disks, compliance and security and many more. Load balancing and high security isalso provided that has made the customer feedback and rating positive in nature (Google). Service Features Linux Hosting & Virtual Machine Management Amazon provides the users with the ability to configure the virtual machines by using eitherpre-defined or custom machine images. There are various options provided to the users in the2
setting up and management of the virtual machines by Amazon in the areas of availabilityzones, size, and memory capacity and so on. Virtual Machine Management (VMM) that is carried out by Google Computer Engine issimilar as that of AWS EC2. However, Amazon is in the business since a longer period oftime and this has a larger customer base. Google has added its own set of features in the areaof hosting and virtual machine management, such as, load balancing, live migration, fasterpersistent disks etc (Stackify, 2017). A Virtual Hard Disk (VHD) is used in Microsoft Azure for the management of the virtualmachines. The number of cores along with the amount of memory that has to be utilized isrequired to be declared in advance in this case. Storage AWS EC2 supports the latest storage solutions, such as, NoSQL databases and the Big Datatools. In this case, a temporary storage location is assigned as soon as an instance is createdand is destroyed at the time of termination. Block storage which is similar to that of the harddisk storage is also involved in this case. Google cloud SQL is involved in this case which supports the relational databasemanagement. Many of the latest tools are also involved such as Big Data tools like Hadoop. Itallows the secure storage of the data at low cost. Temporary storage mediums and page blobs are used in the case of Microsoft Azure. Most ofthe relation and NoSQL databases are supported by Azure for the easy storage of the data(SitePoint, 2017). A comparison between the three service providers and their storage and database relatedfeatures are shown below. 3
Storage and Database – Comparison between AWS EC2, Google Computer Engine andMicrosoft AzureNetworkingAmazon’s EC2 makes use of its Virtual Private Clouds (VPCs) and Microsoft Azure makesuse of Virtual Network (VNET) in order to provide the users with the capability to group thevirtual machines and other networks in the cloud infrastructure. The definition of the networktopologies along with the creation of the subnets, routing of the tables and setting up of thegateways can be done using VPC and VNET. On-premise networking solutions can be extended and converted to the public or hybridcloud models in case of AWS and Azure (Upguard, 2017). In case of Google Computer Engine, one instance is mapped with one network. Addressrange and the address for the gateways for the instances that are connected are defined byusing. Firewall rules can also be applied in it. This adds up to the security of the networkconnections that are involved.
