3MIGRATION TO THE CLOUD1.a)The cloud architecture according to the service can be categorized into followingcategories-Infrastructure-as-service: It provides thefundamental resources like virtual machines, virtualstorage. It also offers- Software bundles, loadbalancers, virtual local area network (Tarasuk-levinet al.,2017). All these things are available throughthe virtualization of the server`Platform -as-service: This models provides the runtime environment for the applications. Apart fromthat, this model also provides the development toolsfor the application. App Engine of Google is anexample of this kind of cloud model.Software-as-service: This type of cloud modelprovides the software applications to the end users.The cloud architecture according to the deployment model can be categorized into threetypes-Public cloud: The public cloud system allows toaccess the services to the people provided by thecloud. Various IT giants like Google, Aamzonoffers this kind of public cloud services via internet.Private cloud: This kind of cloud deployment modelallows the use of the cloud architecture within theorganization.Hybrid cloud: Hybrid cloud allows the merging ofthe public and private cloud (Kousalya,Balakrishnan & Raj, 2017). In this model, the non-critical data and information are stored in the publiccloud, while the important and sensitive data aremanaged by the private cloud.In case of the Regional Gardens, meeting the requirement of the board , theimplementation of the hybrid cloud can be done (Watt, 2016). The confidential data of thecompany can be managed by the private cloud and the non critical data can be stored to thepublic cloud. This will help the Regional Gardens to save the cost of the infrastructure alongwith providing the better service.
4MIGRATION TO THE CLOUDb)Advantages of using hybrid cloud:Hybrid cloud features both public cloud scalability and private cloudscalability.The deployment of the hybrid cloud offers the flexibility of the service.Security is maintained for the public cloud is done by the third party cloudprovider (Chang et al.,2015). However, in case of private cloud , thesecurity can be maintained by the organization itself or the third partycloud provider.Disadvantages of hybrid cloud:The network architecture become complex as both private and publiccloud is involved in the systemThe hybrid model of the cloud is dependent on the internal ITinfrastructure. So, the redundancy across the data centers should benecessary.Advantages of the public cloud:Public cloud enables the sharing of the large amount of resources fromthe different locations among the users. It makes the solution provided bythe cloud inexpensive.The public cloud is flexible to use and it can be merged with the privatecloud.The resources from the public cloud can be accessed from any location.Disadvantages of the public cloud:Low securityLess chances for customization.Advantages of the private cloud:It provides cost and energy efficient solutions to the organization.Private cloud provides security of higher degree.It provides more control over resources.Disadvantages of the private cloud:This model has limited scalability.This model is expensive compared to the other cloud models.The operation is limited to the certain area.2.RisksDescriptionPossible solutions
