1. IaaS instance hosted by AWS/Azure 

The Webb’s retailer store has decided to move their database MS SQL Server 2012 R2 to the IaaS instance in the cloud. There are some consequences faced by the organizational database regarding the privacy and security of their information (Banerjee et al., 2015). The whole idea of this report is to discuss the aspects of the Cloud approach in the organization and thus how much is it efficient to increase the productivity and security of the database in the company selected. In this section we will be discussing about the impact of the strategies.

a. Security Controls implemented by Aws/Azure to protect IaaS instance

The cloud server for SQL has been selected on Azure VMs (IaaS) over the database of MS SQL Server 2012 R2 database. A SQL server on Azure Virtual offers total control over the Windows but also executes cross-database transaction and offers the SQL server (Callegati et al., 2014). This cloud server permits facilitating of different databases according to require and is perfect with SQL server. The hosting   of the SQL Server in the Clouds are done on the Windows Server Virtual Machine (VMs) which runs on Azure (Bourguiba et al., 2014). This platform is also called the IaaS (Infrastructure as a Service). Migrating the present application of SQL servers where every other SQL server application’s version and edition are present.  This likewise executes cross-database exchange however offers add up to control over the SQL server and Windows (Bruneo, 2014). SQL Server or the Azure Virtual Machines (VMs) goes in close vicinity to the class Infrastructure as a Service (IaaS) that has the office to run SQL Server inside the virtual machine in the mists essentially for the online business site in the retail location inside the private cloud that is versatile and secure (Drutskoy, Keller & Rexford, 2013). The execution of Hybrid Cloud is mainly IaaS for the most part has this Policy based for the e-commerce websites. And are private clouds that are scalable and secure.

b. Benefits and limitations of the Security Controls

Reduction in the operational costs along with increase in the effectiveness of Information Technology(Ferretti et al., 2013)

• Reduction of increase in traffic that may makes difficulty for resource scaling
• Faster implementation of the applications as well as deployment for the customers
• Helps in business expansion (Kumar & Charu, 2015)
• Problems such as over growth of the storage can be reduced strategically

Though there are several security issues regarding then scenario of the retail shop:

• Hardening of Infrastructure
• End to End Reporting and Logging
• Authentication and Authorization (Lin, Chen & Lin, 2014)
• End to end encryption
• Usage Monitoring and Data Leakage Protection

2. Risks associated in the Database Migration 

The risk and drawbacks associated with the migration are generally associated with the IaaS infrastructure, database and Communications between the Webb’s  store and their IaaS database in the cloud (Malhotra, Agarwal & Jaiswal, 2014).

a. Risks associated with the migration of the database 

• Data Loss Risk:In the midst of the data migration process, data adversity can happen. Right when the data is migrated to the new system or target structure, a bit of the data may not move over from the source structure (Bourguiba et al., 2014). This peril can be avoided by coordinating data movement testing.
• Data Corruption Risk:Information defilement can simply happen at whatever point the association applies terms and condition and approval over the focused on framework (Callegati et al., 2014). This may make the undesirable information relocate to the new framework influencing the framework with accidents and data debasement. The end client of the application consequently may confront a few issues with respect to the framework.
• Target Application Parameterization Risks:The parameterization chances dependably identifies with the focused on applications (Ferretti et al., 2013). In the event that there are couple of limitations, the focused on framework can wind up noticeably inconsistent with projects of information movement, prompting potential blunder in the framework presented. Movement of information is an extraordinary procedure to battle these dangers.

b. Risks associated with the migration of IaaS infrastructure 

• Semantics Risk: Semantic mistakes can happen at whenever if even the relocation procedure of information has been done proficiently (Tao et al., 2014).
• Extended Downtime Risk: The extended out down time the risk comes when the information relocation process takes substantially more time than anticipated.
• Application Stability Risk: The focused on framework or the focused on application gets temperamental now and again for various reasons that may incorporate uncalled for advancement, wrong coding or shameful coding of the new application in the prerequisite of the business in the new framework (Swathi, Srikanth & Reddy, 2014).
• Interference Risk: Interference Risk can make trouble when more than one partner influences utilization of the application when the relocation to process invigorates.

c. The communications between Webb’s and their IaaS database in the cloud

The IaaS Providers provides development option to more than one platforms: mobile, browser, and so on. This is an easy way to do things that the organization wants to develop the software, and thus this can be accepted from multiple platforms (Sharma et al., 2016).

3. Using Cloud for Backup and Archival of Records 

• By and large the current applications that require quicker relocation with least changes in the mists are executed by the SQL Server in Azure Virtual Machine.
• There is a prerequisite of quick advancement and analyse the situations in the event of not purchasing the SQL server equipment (Hu & Kaabouch, 2014).
• There are groups which can oversee and design the higher accessibility, recuperation from calamities and fixing for SQL servers. To disentangle the administration issues some robotized include are given significantly in the framework programming (Callegati et al., 2014).
• The occasion of 64TB SQL Server bolsters numerous databases according to the prerequisite.
• Aides in movement and developing ventures and additionally Hybrid application.
• With IaaS out in the open cloud, the VMs and the administration running can be controlled (Banerjee et al., 2015).
• Eliminated the cost of Hardware. 

a. Backing up data to the Cloud

There are four risks which are to be considered with backup data to the cloud (Swathi, Srikanth & Reddy, 2014):

• Security
• Lack of standardization
• Control over data
• Outage

b. Storage of data in the Cloud

There are six main risks associated while storage of data to the clouds (Lin, Chen & Lin, 2014):

• No control over the data
• Key management
• Snooping
• Leakage of data
• BYOD (Bring Your Own Device)
• Cloud Credential

 c. Retrieval of data from the cloud 

• Requires higher internet connectivity: High internet speed is required. The accessibility of the database can be let down by any of the issues related to loss of data. Bad connection of internet may result in interruption of data retrieval (Ferretti et al., 2013).
• Data storage in the third party server:It is vital to search for a valued and trusted cloud service provider to avoid getting loss of data by third party server. This may also provide the offers of top-level and contending service (Bourguiba et al., 2014).
• Determine the bandwidth allowance:It is important to limit the allowance since most of the service provides unlimited bandwidth for the retrieval of data that may cost more.

d. DR plan of the CSP

The disasters occur often without any notice and strikes down the business any time. Hence there are several advantages of hosting DR program in the clouds:

• Efficiency: large servers and associated hardware are eliminated since the data is stored in the clouds.
• Scalable: The options of the cloud can easily be scaled depending on the business requirement (Kumar & Charu, 2015).
• Cost effective: The cloud server provider often changes the service thus business has to pick properly which cost should be effectively used. Delay of this may cause immense loss in the cost.
• Elimination of Disks, back-up tapes and many more: In real time data backups can be done hence there is no requirement to keep maintaining the backups by using tapes and disks (Ferretti et al., 2013).
• Easily implemented with high reliability: Difficulty is faced while restoring the functions that are carried out, other than that the tapes, disks, flash drives are suppose to be durable.
• Mission-critical data can be kept off-site: The cloud providers have the DR plans within places thus the servers are redundantly designed and are huge.

4. Cloud Management

a. Their IaaS infrastructure 

There are several advanced choices given by the IaaS providers like the programs, portables and many more. The preferable security can be provided by the IaaS cloud provider. IaaS is itself an infrastructure that provides resources to the virtualized computing over the internet. The security provided by the association’s primary business (Tao et al., 2014).

b. Their Ms SQL Server 2012 R2 cloud instance

The SQL Server are installed and thus hosted in the clouds. This is done over the Windows Server Virtual Machine (VMs) which runs on Azure which is also known the IaaS (Infrastructure as a Service). On Azure Virtual machine the SQL server has been optimized to migrate to the existing application of SQL server (Swathi, Srikanth & Reddy, 2014). Cross-data transaction has been included but this also offers total control over the Windows and SQL server. SQL server or the Azure Virtual Machine (VMs) serves IaaS and allows running SQL server inside the virtual machine in the clouds.

c. Their Cloud network infrastructure

Profoundly adaptable assets have been offered by the IaaS stages which are balanced as per the requirement. The regulatory assignments mechanization are different in qualities if IaaS situations incorporations, desktop virtualization, dynamic scaling and administration that are policy based (Malhotra, Agarwal & Jaiswal, 2014).

d. Their Cloud backup and restore infrastructure

The primary security functions are used by the cloud services in traditional ways but the hackers found the ways to log in or access through the security protocol very easily. Every vendors follow different protocols to support the business. Migrates all the information to the cloud server in some unknown location via the cloud providers. This can make one feel like they no longer have the control over the database (Drutskoy, Keller & Rexford, 2013).
