A report regarding the involvement of risks in cloud migration
There can be a lot of involvement of the risks and the threats while the
implementation of the migration to the cloud services (El Kefel & Mohamed, 2013). It is
known to almost all theat risks involved in a particular task will be there since there is no
option to completely eliminate these risks but the risks involved in the task can be mitigated
to gain out of the best of the services (Brender & Markov, 2013).

Migration of the services and the Strategies of Migration
Response to Question 2a)
The MetaSoft board that intends to shift their SharePoint instance and the SQL
database server to the AWS cloud in order to initiate the migration process and test their
respective strategies accordingly (Varia & Mathew, 2014). The steps that would be necessary
to in planning the migration of these services includes the installation of the SQL drivers and
the AWS Schema Conversion Tool on the local computers of MetaSoft, configuring the
company’s Microsoft SQL server source database, configuring the company’s Aurora
MySQL database, usage of the AWS SCT to convert the SQL Server schema to Aurora
MySQL, creating an AWS DMS replication instance, creating AWS DMS source end target
endpoints, creating and running the company’s AWS DMS migration task and ultimately
cutting over to Aurora MySQL (Mauch, Kunze & Hillenbrand, 2013).

The steps mentioned above collectively will help the MetaSoft to shift their
SharePoint and the SQL database servers to the AWS cloud with relative ease. This will also
bring a flexibility to the system. The total number of eight steps in the migration process will
not only bring an integrity to the system, but also will help in the facilitation of the services
(Amazon, 2015). The step by step migration process mentioned in this section is provided
according to the prior knowledge that the MetaSoft board is well aware of the perquisites
require before the initiation of the migration process. The main idea behind the shifting of
the SQL server databases to a cloud service is to bring in a fluency to the entire system. It
will help the organisation to retrieve and store information from anywhere unlike the older
version of the SQL database servers.
Response to Question 2b)
In the course of migrating the services from the SQL database server to the AWS
cloud there can be some that could prove to be equal or even there could be issues at each of
the steps. Some of the critical points and the issues are identified and discussed in this section
(Andrikopoulos, Strauch & Leymann, 2013). In the first step of the migration process, the
appropriate link should be used to download the AWS SCT otherwise a downloading a wrong
file will hamper the entire process of migration process. In the second step of the migration
process, special attention should be given to the type of the SQL database server for
replication is not supported if the SQL server database is an Amazon RDS database. In the
third step of the migration process, it is important to have a user to connect to the target
database as a dedicated new user or an existing user is vital to grant the privileges
(Mendonca, 2014). In the fourth step of the migration process, it is important to enter the
right server name, server port, username and the password for testing the connection as these
details are essential for establishing a successful connection. In the fifth step of the migration
process, it is important to specify the replication instance information because the valid

information will determine whether a replication instance will be created or not. In the sixth
step of the migration process, it is a must to drop the foreign key constraints and trigger on
the target database because this will help in the generation of the script (Zhao & Zhou, 2014).
In the seventh step of the migration process, it is necessary to give a special attention to the
migration type because the migration type determines what type of migration it will be. In the
eighth step, the SQL service should be properly terminated to avail the cloud services.
