WEBB’S DATA MIGRATION PLAN Webb Stores a successful retailer with various stores across AUSTRAILA and New Zealand wishes to migrate from the current data management infrastructure to a cloud based infrastructure due to variousadvantages such as:●Flexibility and responsiveness of data●Better management of data●Costs saves of ICT infrastructure1.Migration from MS SQL Server2012 r2 database to IaaS cloud infrastructure however has to overcome certain challenges one being security applied to the data once migrateda.First of all, Infrastructure as a Service model provides highly scalable resources that are flexible in which makes It ideal for temporary and variable workloads.oConsidering the security implications Iaas should be implemented in accordancewith the following measures in place;oUse of a private cloud to gain total control of all assets for enhanced security. A private cloud is an internal data center of the organization that is not openly available to public. In private cloud configuration, assets, resources and services are owned by the system, but those are accessible internally.oApplying data access procedures in especially business critical data. Thatis by implementing Rights management operations and applying restrictions to all information that is considered business critical. Create policies for this information and then deploy those policies in a way thatdoesn’t require user interventionoApply authentication and authorization procedures for data access. Obviously, in order to have an effective Data Loss Prevention (DLP) solution – you have to have robust authentication and authorization methods in place such as tearing your access policies based on the level of trust you have for each identity provider for your IaaS cloud solutions. An Active directory management service should be implemented oInitiating procedures that ensure efficient recording/logging at both read and write. Iaas infrastructure demands that you have comprehensive logging and reporting in place. For keeping track of where the information is, who accesses it, which machines are handing it, and which storage arrays are responsible for it, you need robust logging and reporting solutions.
.oCryptography and network security should be core to prevent and deterattacks (Mark, 2011). This also prevents offline attacks. Deploy mechanisms such as homomorphic encryption to keep end-user communications safe and secure. This is a form of encryption that allows complex calculations to be performed on the data even though it is encrypted.b.On Deployment of this features this will in turn offer certain benefits to the model such as; oPrivate cloud infrastructure gives you total control over your assets, hence one is able to create and deploy polices that govern rights access to critical data.oData stored at the datacenter is increasing day by day it leads into huge amount of data storage in cloud and results into issues such as data loss,data breach etc. There is a need of an efficient technique if the data get destroyed or deleted by mistake to recover the data from any backup serveroCloud computing makes it easier for enterprises to scale their services – which are increasingly reliant on accurate information – according to client demand. Since the computing resources are managed through software, they can be deployed very fast as new requirements arise. In fact, the goal of cloud computing is to scale resources up or down dynamically through software APIs depending on client load with minimal service provider interaction. (M.A.G 2014)oAuthentication and authorization procedures allow for creation of an active directory that is more ‘strong’.oLogging is critical in the system as it allows for easier error and hacks detection if they occur (n.d 2017.).oUse of cryptography and network security procedures with no doubt deters but as well prevents any attacks to the system.2 Risks associated with migrating mission critical database to the cloud.a. Database architecture might not ideally have distributed cloud based architecture hence might be a challenge on implementation of the same. services that can support continuous backups to reduce the chance that bandwidth constraints could cause issues, and monitor your bandwidth usage. ( Manes, C. n.d 2011.).b. Database performance. Database performance can be defined as the optimization of resource use to increase throughput and minimize contention, enabling the largest possible
