Hybrid Cloud Architectures PDF

Added on - Sep 2019

This report is based on "Regional Gardens Ltd. cloud computing". We will discuss here hybrid cloud architecture is defined as the integration of on-premises resources along with the cloud resources. The hybrid cloud architecture will allow the organization the opportunity to explore new products and business operations at all times. The migration of legacy IT systems is not easy and it takes time. The selection of the cloud provider, therefore, needs to be done in such a manner that the hybrid cloud strategy is successfully implemented and costly new investments are not required.

Regional Gardens Ltd.Hybrid Cloud ArchitecturesAWS Hybrid CloudHybrid cloud architecture is defined as the integration of on premise resources along with thecloud resources. Regional Gardens Ltd. is an organization that needs to preserve it on-premises technology and include enhanced cloud resources to carry out its businessoperations. Hybrid cloud architecture has therefore been proposed for the organization. Themigration of legacy IT system is not easy and its takes time. The selection of the cloudprovider therefore needs to be done in such a manner that the hybrid strategy is successfullyimplemented and costly new investments are not required. Amazon Web Services (AWS)hybrid cloud architecture has been recommended for the organization to simply the businessoperations and to allow the company to achieve its business goals.AWS Hybrid Cloud ArchitectureAWS has developed a wide range of hybrid cloud services and activities across theoperations, such as data storage, security, connectivity and networking, deployment of theapplications, management tools, and several others. The AWS hybrid cloud architecturewould allow the organization to integrate the cloud securely and easily with the existing2
Regional Gardens Ltd.architecture by extending the current investments (Aws, 2018). The AWS hybrid cloudarchitecture has been shown in the figure above.It has been recommended for the organization as it will economically store massive sets ofdata and will provide mechanisms to utilize the new cloud-native databases. The customerwill be able to clearly view the data sets and there will be enhanced transparency developedbetween the customers and the organization. The backup of the data sets will be possible tobe developed in a cost effective manner. The hybrid cloud architecture comes with a storagegateway service. The service will seamlessly integrate the existing and newer cloudcomponents. It follows a multi-protocol storage appliance coupled with extremely efficientnetwork connection to deliver enhanced performance to the users.The second layer of the hybrid cloud architecture provides the mechanism to connect the on-premises and cloud resources with the aid of a common network to develop a singleenterprise environment for enhanced security. The extension of the network connections maybe easily done so that the AWS resources operate the cloud operations as part of theorganization. The physical connectivity may also be extended so that a dedicated and privatenetwork connection may be set-up. Integrated identity and access strategy is another reasonthat is present behind the selection of the cloud architecture. The cloud architecture will allowthe creation and management of the various users, user groups, access, permissions, andidentity in extreme detail. There are managed services that are offered by AWS to connect theresources with Microsoft Active Directory and to merge the policy with the existing set oftools. The extremely robust hybrid architecture involved integration of the applicationdevelopment, application deployment, and management strategies across the variousenvironments. VMware is also one of the close associates of AWS and there is a relationshipthat has been developed between AWS and VMware to carry out the cloud operations andactivities.Benefits of the Hybrid Cloud ArchitectureThe primary benefit that hybrid cloud architecture will provide to the organization will be interms of flexibility and scalability. The business operations of Regional Gardens Ltd. arecontinuously changing and there may be increase or decrease in the demands of cloudservices that may be observed in the years to come. The hybrid cloud architecture will allowthe organization with the opportunity to explore the new products and business operations atall times. One of the primary concerns with cloud platforms is the downtime due to3
Regional Gardens Ltd.occurrence of security risks or availability issues. There is also a lot of maintenance time thatis demanded by the other cloud platforms in the market. However, hybrid cloud architectureis stable as it includes the features of private as well as public cloud (Xue & Xin, 2016).There is highest degree of stability that is promised and comes along with hybrid cloud.These cloud architectures are also cost-effective in nature and have reduced latency.Issues with Hybrid Cloud ArchitectureThere is an increased infrastructure dependency that comes along with hybrid cloudarchitecture. For any of the cloud-related issue or outage, there is a lot of reliance on theinternal IT staff. Security is another primary concern that is witnessed with the hybrid cloudarchitecture. There may be security issues as lack of encryption, denial of service anddistributed denial of service attacks, malware attacks, data leakage, authentication issues, etc.that may come up (Jenkins, 2014).Risk Report for Hybrid Cloud & MicroservicesList of Risks IdentifiedRisk NameDescription of the RiskEncryption IssuesThe data sets present on the cloud platform may not beencrypted properly leading to the exposure of informationproperties and contentsDenial of Service &Distributed Denial ofService AttacksThe malicious entities may launch garbage traffic on the cloudconnections which may disrupt the availability of the serviceand the data setsMalware AttacksThere may be attacks of malicious codes, such as viruses,worms, logic bombs, ransomware, and othersData LeakageThe data and information present on the hybrid cloudarchitecture may get leaked in between that may impact theintegrity of the information setsUnprotected APIsAPI endpoints may be utilized by the malevolent entities toexpose the sensitive data and information setsAuthentication & IdentityIssuesAccess to the sensitive and confidential data sets to theunauthorized entities due to poor authentication and identitymanagementPoor IP ProtectionThe protection measures installed for the sensitive andconfidential data sets may not be adequate (An, Zaaba &Samsudin, 2016)4

Introduction to Hybrid Cloud on AWS

From the above report "introduction to hybrid cloud on AWS", we conclude that the possible risks in the process were also highlighted and the risk management plan should be formed. The performance of the services and the data sets on the AWS cloud will be tested in terms of the impact of load and load balancing abilities, response time, and throughput time. We have also discussed here the development of cloud computingThe change management plan includes the steps of change planning, change execution, and change management.
