Ubiquitous Access Resources Such Servers â€Myassignmenthelp.Com

Question: Discuss About The Ubiquitous Access Resources Such Servers? Answer: Introducation Cloud computing is a computing software and infrastructure model which is used in enabling ubiquitous access to resources such as servers, applications, storage and networks which have been configured and can be allocated and managed with minimal effort through the use of the internet (Hamdaqa, 2012). A hybrid cloud is a term used in cloud computing to refer to a cloud computing environment that utilizes a combination of private cloud, on premises infrastructure and third party cloud services which work together to bring about the whole cloud computing solution to a company. Cloud computing is in some aspects referred to as Infrastructure as a Service (IaaS) because it provides computing resources over the internet which are virtually available. Webbs is a company which is trying to use cloud computing to optimize its operations and save on some of its operational costs. They want to migrate their MS SQL Server 2012 R2 database to an IaaS instance. The types of security they can deploy to protect data through migration to a public cloud are data in motion encryption such as using a virtual private network (VPN) or a secured socket layer (SSL). An SSL is a security technology which is standardized and used in establishing a link which is encrypted between a web browser and a server. The benefits of that would result from this deployment is that the data of the company will be safely secured and will not be easily accessible to outside individuals. The data will also be easily accessible from anywhere which allows a lot of portability to the employees of the company. The issues that would arise would be that their data will be at risk to a new breed of people such as hackers who can try and attain this data for personal, professional or financial gain. The risks associated with migrating the mission critical database to the cloud are that the database can be compromised because all the data from the database will be migrated to the cloud and during this migration data can be tapped by an unwanted party which can lead to there being a serious security problem in the company. The IaaS structure can pose various risks such as being too slow to effectively serve the company as data is being migrated. It can also have low or unsubstantial security measures which may put the company data at risk of being breached or accessed by unwanted parties. Communication between Webbs and their IaaS happens over the internet which means that the link can be breached through an instance such as a man in the middle attack (Kostantos K. et al., 2013). The risks and issues associated with backing up data to the cloud are that data can by accessed by unauthorized users. Data also takes a lot of time to be uploaded to the cloud which can cause a lot of lagging in the operations in which the company undertakes. There are also risks to restoring or retrieving data back from the cloud because this process needs to be a fast task and may take a lot of time due to the huge volumes of data which are needed for use by the company. Storing data in the cloud is critical because this data is sensitive and needs to be secured. It is therefore a key requirement for storing of data to the cloud to be very secure and organized. When the cloud is built and organized well it ensures that we the company can access data efficiently reducing any issues of data redundancy or coherency which are usually present in a poorly designed database (Qusay, 2011). Webbs use of the cloud backup affects their DR plans in that they will now have to change their strategy. Data recovery involves saving data or backing it up somewhere such as a cloud then later retrieving this data in case maybe the system is compromised. Webbs DR plans were internal but now they use the cloud which means their data is passed over the internet and can be accessible by unauthorized users if it is not protected. Webbs needs to ensure that in backing up and retrieving their data they utilize data in motion encryption techniques to secure their data. They did not need to consider such measures before because data recovery was handled using in-house infrastructure but now they will need to use the Iaas infrastructure. Webbs can protect their Iaas infrastructure by using multi-factor authentication when accessing this infrastructure. This will ensure that authentication to access the infrastructure is more secure so that it is hard for any unauthorized users to access the infrastructure. Administrative access can be limited to only a few users to ensure vulnerability is limited because there are only a few users who have administrative access (Von Laszewski et al., 2012). These protection measures can be replicated to their Ms SQL Server 2012 R2 cloud instance. Their cloud network, backup and restore infrastructure can be protected by using data in motion encryption and firewalls to ensure they are secure from threats and any data they are passing over the internet is secured and encrypted.
