Discuss about the Global Information Systems Strategy for Cloud Computing.
Hybrid cloud computing is the mix-up of the private and public computing. Hybrid cloud computing can be used for both public and the private services. It is the environment in which a mix on premises can be used for the private and public cloud services. In this type of computing, the workload can be moved between the private and public clouds according to the cloud computing needs. It provides a high flexibility to the business and some or the options for the storage of the data. The company can migrate its data to the public computing also (Chen and Zhao 2012).
Implementation Strategy:
There are three Implementation strategies of the hybrid cloud computing
A less sensitive data and can be hosted by using some public resources or any browser such as Google and Mozilla. This digital business enterprise can migrate its data to hybrid cloud computing by using on-premises private and public computing. On-premises private cloud can be created to store the secret and sensitive data. If there is need of confidential storage of data, a private cloud can be developed for critical data storage (Garrison et al 2012). This type of cloud computing is costly.
To create a hybrid cloud is difficult to develop and similar to create a data center. It is necessary to note that all the sites and the clouds should be connected to each other. All the sites of this organization can be connected using IPsec virtual private network or through a direct connect line. On the basis of the requirement of the bandwidth and security, decision criteria can be chosen. In this organization, high bandwidth is required, then 1to 10 Gbps direct connect line can be used to provide the high throughput so that traffic cannot occur over the network or internet.
Hybrid cloud computing can be hosted using Amazon Simple Storage service. In Amazon web service, private cloud connection to the public clouds can be established by using eucalyptus software layer So, to store the transaction details, a high space for data storage is necessary. Authentication is the main issue to develop the hybrid cloud model. In this organization, four different services are running off-premises in the cloud. So the authentications against directory services may cause of authenticating the traffic. So the authenticate traffic can saturate the virtual network private network. There is a need to extend the directory to the clouds by creating a new authentication site. In this multiple business organization, one virtual data center can be attached to higher performance storage (Garrison et al 2012). The other data center will be attached to the economical standard tier of storage. By using this policy, multiple businesses can direct the application to the best location.
If this company is going to implement the hybrid cloud then it is very beneficial for the company in the terms of security. It is more secure than public clouds. In-house storage for the secret data can be maintained by using hybrid clouds. The size of the hybrid clouds is more spacious than public clouds. So, there is no problem of limited storage space. The data in bulk can be stored in hybrid clouds because there is a great space in hybrid clouds to store the data. Hybrid Clouds reduces the cost for the data storage (Hwang et al 2016). It is very beneficial for the company, because the cost of data storage is low than other. It reduces the complexity to maintain the hardware. The permanent data can be stored in the private cloud of hybrid cloud. The less sensitive data can be stored in the public cloud of hybrid cloud. It reduces the requirement of man power. The data can be easily migrated to the hybrid cloud. There is no need to maintain the hardware for the storage of the data (Li et al 2013).
It reduces the cost of storage and the manpower. The data backup can be created easily by using the hybrid clouds. As, this is the multi-business company so for the various purpose; hybrid clouds can be used (Zheng et al 2014). There are both options available together as a public cloud and private cloud. The data can be stored according to the storage need of the data (Paul et al 2013). The hybrid clouds are also useful for the increment of the internal assets of the company. It also improves the external services provided by that company (Kovachev et al 2014). Hybrid cloud is useful to main the isolation of the company. It is also useful for the recovery of the information at the time of lost of information. If any case of disaster occurs, the information can recover by using the hybrid cloud at the time of any disaster. The data can be tracked easily by using the hybrid cloud computing.
There are risks of hybrid cloud computing given below:
A very sensitive data cannot be stored in the hybrid cloud. It is the limitation of hybrid cloud. It is very complex to develop the hybrid cloud. If there is some legal software is using in the company then this software can’t be use over the cloud (Moreno-Vozmediano et al 2013). There will be high latency and data traffic while cloud applications are running over the internet.
If various technology relies on is proprietary, then a cloud cannot be deployed legally.
There may be a problem of the high latency when the cloud application is using over the internet.
Some transparency can be lost and control while debugging performance issues
The services that will use in this type of cloud migration are given below:
IaaS – Infrastructure as a Service (AWS, Azure, Google Compute Engine).
SaaS – Software as a Service (examples: Google Apps, Salesforce).
Figure 2
Here’s where you’ll have to make an important choice. To host their applications in the third-party data center and to outsource the care of physical infrastructure, it is necessary to concentrate on development and the monitor of the applications. IaaS must select for this kind of applications. It is very helpful for the appropriate storage of data and for the virtualization (Sitaram et al 2015).
SaaS is a delivery model through which centrally hosted productivity software is licensed on a subscription basis. SasS is helpful to maintain the CRM, security of the data and for the management of the business.
Hybrid cloud can work by using a hypothetical scenario. Let’s imagine that this web app is quickly gaining popularity and users. In order to keep up with the growing demand, there is need to maintain the resource to scale up dynamically. It is beneficial to deploy maximum resources serving requests during the high demand and at the time of demand drops, it is simple to drop unneeded resources to save costs by using the hybrid cloud with the IaaS and SaaS services.
Hybrid computing is the best solution for the highly dynamic data. This is the multi-business company and this company also provides the tourism and healthcare facility. Hybrid cloud computing can also be used to host the data and to manage the data backup. Hybrid clouds can be computed using at least one private and public cloud (Srinivasan et al 2015). The development of the hybrid cloud is not simple. There may be problem of the integration. There may be the problem at the time of data migration. But with the help of Amazon web services, Red Hat and VMware hybrid clouds can be developed (Zisssis et al 2012). Migration of the data to the hybrid cloud is the good strategy to make the data secure and to reduce the cost including the workforce and data storage. This organization is providing the booking, healthcare and the tourism facilities, it a multi-business firm, so the use of hybrid cloud is the best solution to reduce the data storage complexity.
Conclusion:
Hybrid cloud is the best for the data storage. It is complicated to manage the hybrid cloud but it saves the times to track the data. The main point of discussion in this report is the data migration of the company to the hybrid cloud. So, the hybrid cloud is the main point of the discussion that is above discussed. There is no requirement of the staff to maintain the data. In short, to implement the hybrid cloud is beneficial for the organization.
