Abstract
The larger infrastructure, data centers, server rooms and
storage are occupying more area in any organization. The organizations wants to
reduce these problems and then cloud computing emerged as a solution. Cloud
computing provides all these hardware infrastructure, server rooms, data
centers, storage, networking unit and much more virtually. Every of these
services will be accessed with the help of the single desktop application.
Cloud computing thus offering both the hardware and the software services to
the users. Cloud migration has been the hot topic in the recent years as the
services are much satisfying and reducing costs in terms of management and
maintenance. Also it will be costing very higher for medium and large
enterprises for purchasing data centers, servers and other networking devices.
With the help of cloud services these issues could be easily tackled. Cloud
services are developing day to day in order to enhance and innovate new
services. Computing services like hardware and software could be virtually
accessed with the help of the cloud computing. There are several types of cloud
computing services and they are discussed in this report by studying some of
top cloud service providers and their services.
Introduction
Cloud computing has multiplied its role and the involvement in different types of sectors. In the current and the past decade, most of the companies are migrated to the cloud based services. The reason behind the cloud computing based migration is that to reduce the usage of infrastructure and hardware in the organization. The use of hardware, servers, networking equipment, storage devices and much more could be reduced once if the organization moves to cloud services. In addition to that cloud provides various services like application development, Artificial Intelligence, Internet of Things, Machine learning, etc. There are different types of cloud services and models in the market and the best and the suitable one should be selected for migration. The models are Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). As the name denotes, each of these services will be offering various services to the users. They are again categorized into private, public and the hybrid cloud. Thus, each of these models and services offered by the various cloud service providers should be studied and compared to identify the best out it. It will also be helpful in understanding the services that are offered by these services. The following report will thus be helpful in studying and understanding about the cloud services providers and their comparison.
Cloud service providers
Identification of cloud service providers
Due to the digital transformation of the businesses, every information technology applications has been developing. Cloud computing has seen enormous development in the recent years and business have been migrating to cloud in large numbers. For migrating to the cloud services, the organizations may choose any of the model from Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). These services are provided by more number of cloud service providers in the market and the right out of them should be selected. In order to identify the right could service provider, the comparison between them will be helpful. The following section will discuss in detail about the four top cloud service providers. Out of them the best one is selected to compare with the IBM cloud to understand various features of them.
Amazon Web Services
Amazon Web Services or the AWS is the leader in providing the public cloud services. It also became the major service provider in database, Artificial Intelligence, machine learning and the serverless deployments. Apart from the cloud computing and the cloud storage, it has expanded to various integrate with the above said technologies. It is the world leader in the cloud computing providing all cloud models with greater than 200 integrated services to the users (Larry Dignan, 2021). The 33% of the entire cloud market is shared by AWS with 77 availability zones and about 24 geographic regions. The size of the AWS platform is massive and has been breaking out its own figures in sales and services. There are several cloud service providers who had emerged in the recent times and had become the competitor for the AWS. With the help of VMware, AWS offers the virtualization technology to build virtual network in the organizations.

The data analytics based on machine learning and deep learning is also offered through the cloud service platforms. It is in the top of the stack in terms of applications and deployments of integrated cloud services (Mahesh Chand, 2021). Google Cloud Platform has been moving towards the multi-cloud services it is expected to offer more services to its users in the near future. It is mostly providing services for the financial and the retail customers around the world. The sales strategy that is used by Google Cloud has been improving as they are pioneer in selling services and products to the people.
Oracle Cloud
Oracle cloud platform is the latest and last one to develop cloud based services of these all four. It is offering the IaaS, PaaS, SaaS and DaaS services to the customers. The services that Oracle is offering is in the infrastructure, database and platform in addition with the SaaS. It is covering the services to small, medium and the large enterprises. Oracle is working heavily in order to provide improve its strength among the customer base. Despite of the late start, Oracle has been playing aggressively to attain the credibility in the market. Though the organization is based on software based services, it has been now planning to improve in the field of IaaS and PaaS offering to the customer base it has. It is providing the second generation cloud with capabilities of improving the performance and optimized workloads (James Maguire, 2021). In some areas, Oracle cloud outperforms the AWS and is having the maximized performance.

Managing the Apps & Sever in the Context of allocating & upgrading the resources
Manage the resources of the application and server, especially through allocation of resources among the other relevant programs. In this case, it typically includes the resources like the devices of input/output, network connectivity, file storage, central processing unit and the computer memory. The tasks based on the management involves the usage of scheduling resources to overcome the interference and conflicts between the programs. With the help of the memory management, it allocates and de-allocates the memory space in the applications and the servers. Through this system, it keeps track the memory space and it also how much of the memory space has been utilized and by whom the memory spaces were occupied (Prasad, 2019). Privacy has been offered through the server by the means of a password so in which the un-authorized apps cannot access the data or programs. For instances, the servers could utilize the authentication of Keberos to overcome the un-authorized accesses to the data. The memory and the input/output space can be increased dynamically through offering the additional servers for storage as required.

Opinion based on the comparison & contrast of cloud providers
Choosing the better service provider
Both the Azure and AWS is more of the business decisions to move to the cloud oriented environment. How-ever, the reality in which it is not a technical based decision. Both the Azure & AWS were the performers of solid with the equivalence of almost 99 percentage of use cases. Selecting the AWS and Azure is more of the business decisions and that depends upon the organization requirements or needs. For instances, while the companies are in need of the strong provider of PaaS or requires the integration of windows, Azure would be more preferable option when the enterprise is seeking for the IaaS or some diverse set of a techniques then the approach of AWS might be a better solution (Rösch, 2016). More recently, the other parameter for making the decision is that how much the built-in tool of analytics was available on these platforms. Such kind of tools could help more in releasing the analytical project at the faster rate. In this case, it suggests to adopt the cloud service provider to be AWS. Because, it includes the flexible pricing and that can be more useful for the organization to adopt it. AWS includes the market place of software with an eco-system of extensive partner with the Linux and Windows. In the provider of AWS, security has been offered by the user-friendly roles with the permission of exceptional control. This could also offer the excellent implementation for the security groups and granular IAM.
One improvement area to see for the proposed services
While, it must never be a single or most major factor, there is no denying in which the cost could play a major role in deciding which the provider of cloud service has to choose. It is helpful to look at both the price of a sticker and the associated costs. Support is the other major area in which it needs to be considered for the improvements. In some situations, support can get by the service of chat or the call center (Attaran, 2018). The level of service is the other major area in which it needs to be considered while the business includes a strict requirement in terms of the support, response time, availability and the capacity. The agreement of cloud service are the major elements in which it needs to be considered while selecting the provider. It is major to establish the contractual relation-ship between the provider of a cloud service and the cloud service consumer. In this case, it includes some abilities to trust the provider of cloud to do a right thing and requires a legal agreement in which it could back-up while some-thing goes wrong.
Conclusion
From this report, it discusses about the providers of cloud services. In the first section of the report, it identifies and discusses the four different providers of cloud services who provides IaaS and PaaS for the medium to a larger enterprise. From the identified service provider, choose one service provider and compare it with the IBM cloud IaaS and PaaS services. In the second part of the report, it compares and contrast with the IBM IaaS and PaaS cloud. Under this section, it discusses the navigation and quality of IaaS and PaaS system, level of complexity for the deployment operation of cloud environment, describes some process that how it is easier to maintain the server and apps in the context of space, memory and so on. In this case, it also discusses the step by step operation in which it is required to create and develop the application of hello world or the instance of IaaS. Finally, in this report, it discusses some of the opinions based on the comparison and contrast of the cloud providers. Through this, the organization can adopt one of the better service providers.
