Cloud Computing


1.Specify the service model and deployment model(s) you want to integrate.

The technology revolution has made it possible for companies to transact their operations irrespective of distance; the applications come along with prompt, effective and efficient services. In this paper, I will elaborate about cloud computing servers and security threats in addition to solutions. Cloud computing is the process of storing and accessing information and programs via the Internet as compared to the standard hard drives of the computer. On the other hand cloud computing architecture is the software capabilities, databases and other application designed to influence cloud resource’s ability to resolve business problems such as cloud, premises resources and middleware (Mell & Grance, 2011).

Cloud architecture core function is to offer business people with continuous access to information and applications, high-speed bandwidth, network security and active network. Cloud architecture characteristics comprise of Software as a Service (SaaS), the application hosts the software on the Internet thus users access Software locally minus installing.  Also, Infrastructure as a Service (IaaS) offers hardware and infrastructure; servers, storage, networks and devices. Lastly, Platform as a Service (PaaS) allows business people to access to the database application platforms, i.e., middleware services (Mell & Grance, 2011).

SaaS is the dominant application in the market application and runs in Web and customers do not require to download, but plugins details may be necessary. The application is managed by a third person and the user has no control. Business people can streamline for support and maintenance services. The application handled by vendors i.e. services of, data, runtime, middleware, OSes, servers, virtualisation, networking and storage. The basic types of services are healthcare applications, email and customer relationship. The apps are Salesforce, Google Apps, Concur, Cisco WebEx, Citrix GoToMeeting and Workday (Mell & Grance, 2011).

PaaS clouds are applications and development that are essential in offering cloud components software that are necessary for the server to work.  The developer will enjoy the services provided by Pass that has two major suites, Integration Platform as a Service (iPaaS and Application Platform as a Service (aPaaS). APaas provides ecosystem, development and management application tools in addition to the business application (Mell & Grance, 2011).

APaaS solutions are like Microsoft Windows Azure and Google App Engine. On the other hand, the iPaaS supports the integration and governance by coming up with application infrastructure to support the system. The iPaaS, developers are flexible in developing and implement integration flows linking different applications. The vendors develop the software, test, launch for fast, easy and cost-efficient services. The third-party operator handles the OSes, servers, networking, storage, the software in addition to developing applications that are compatible with both private and public cloud (Mell & Grance, 2011).

IaaS are independent models for datacenter infrastructure and users can access, monitor and effectively manage all the running applications. The applications are, storage, virtualisation, networking services, etc. The clients can legally access the hardware through buying IaaS on demand of using the appropriate service. Unlike SaaS and PaaS, users of IaaS are accountable to managing data, applications, OSes and middleware. The major applications are Amazon Web Services (AWS), Microsoft Azure, Cisco Metapod, Joyent and Google Compute Engine (GCE) (Mell & Grance, 2011).

The US National Institute of Standards and Technology (NIST) categorised Cloud computing into four major groups such as the public cloud, private, hybrid and community cloud. Private cloud entails leasing of infrastructure to an organisation that is operated by that company. The computing architecture is usually hosted privately by a network, for example, the internal LAN systems. Private computing administrators manage the organisation’s network courtesy of in-house Internet service providers to execute duties to the employees (Mell & Grance, 2011).

Public cloud branded as the external cloud. The services are chargeable, i.e., customers are supposed to pay a subscription fee to access the services of a remote server through the Internet alternatively. The public cloud comprises of infrastructure that are properties of an organisation that sell cloud services to the public. The sharing of infrastructure with common requirements for instance, security referred as community cloud. While the hybrid cloud is an organisation that uses multiple cloud models in its activities (Mell & Grance, 2011).

I will choose the hybrid cloud that is a combination of public, private and community clouds that work well for both large and small entrepreneurs. The major advantage of combining different infrastructures into a single operating system is to boost the computing architecture into a more reliable, cost-effective and optimise the performance. Hybrid cloud is secure; the architecture performance can be regulated to offer prompt services thus beating deadlines in the execution of services.  The application also allows the user to meet the billing requirements in advance (Mell & Grance, 2011).

A hybrid cloud combines the public and private approaches to host the application depending on the sensitivity of data. Sensitive applications are accommodated in a private application while on the other hand, the application is not vulnerable to attacks that may lead to exposure of vital information stored in the public cloud.  In most cases where entrepreneurs use the public cloud, they do not store all the information on the cloud server. The sensitive applications are hosted internally while the rest stored in the public cloud (Mell & Grance, 2011).

Thirdly, hybrid cloud, one can access its particular system and control the network requirements irrespective of the physical and logical segment in addition to allowing multi-tenancy. The system allows a user to customise the hardware to meet the commanded requirements according to the needs of the customer. Also, the system allows the user to select the best servers and network gadgets which are effective and efficient in barring the sites that pose as a security threats (Liu, et al., 2007).

The other reason for choosing the hybrid cloud is the compliance requirements that are compatible with the safety of the system. For instance, auditors demand multi-tenancy solution that boosts the hosted infrastructure. Hybrid if combined well with a strong network safety and specific hardware, it is the best for account requirements. Also, the issue of billing and all the methodologies used in pricing is a major challenge in seeking cloud computing services. The hybrid offers a portfolio that comprises of customer’s account to reduce the stress of figuring out and also build a good relationship with the vendor (Liu, et al., 2007).

Hybrid offers the best utility billing since one pays for the services that a user needs in and the hardware. Sticking with the best servers that provide overflow of traffic is essential in meeting the ever demands goals of an organisation and hybrid complies with the requirements. Lastly unlike public cloud operators who offer various choices of operating systems which is essential for multiple customers who must test all the technical ability but, with hybrid, one will only require a dedicated server for specific requirements (Mell & Grance, 2011).

2.Discusses specific existing vendors that may assist in your implementation.

Hybrid cloud is the now thing as many business entrepreneurs are shifting from the traditional model to the modern way. The switching process demands cloud integration, security, management, networking, automation and consulting. Hybrid computing services model comes with multiple services, i.e., Saas, Iaas and PaaS. It is always advisable to select the best vendor firm with the consideration of the current and future resources demands, plan effectively to get \reliable, flexible and efficient services (Mell & Grance, 2011).

The major hybrid cloud vendors are VMWare, Amazon Web Services, Microsoft, Rackspace and EMC. VMWare provides the hybrid cloud services through the vCloud Hybrid Service (vCHS) that runs the support of the cloud through the vSphere. The vCHS acts as the protective hybrid cloud service. The system supports workloads, application innovation and also third-party application. The servers use various tools such as vCloud Automation Center, vCloud Connector, and vCenter Configuration Manager. VMware major models comprise of the IaaSproducts that encompasses of Disaster Recovery Cloud, Dedicated Cloud and Virtual Private Cloud (Brooks, 2015).

Amazon Web Services (AWS) is a cloud computing operator that provides the PaaS and IaaS service models (Brooks, 2015). The company integrates the public and private data centres courtesy of Direct Connect. Amazon is recognised for offering public cloud services. The firm supports spikes usage on-premises integration and controls the system through the Active Directory, Access Management an Amazon service. Amazon is profitable through providing the network and also boosting bandwidth.

The other vendor is Microsoft, the company offers IaaS and PaaS services that come along with management support services. Windows Azure platform offer the public cloud users with that opportunity of venturing into innovation and successful migration. The latest Microsoft’s Cloud Platform System (CPS) supports organisation documents that are sensitive. The current technology world demands update of information to boost the performance of a system for fast, efficient and reliable services (Brooks, 2015).
