The modern world is currently being continuously impacted by the rapid growth and advancements in technology. Not a single day passes without there being an innovation made in an area of information technology with the goal of solving life’s problem while increasing stability, interoperability, and efficiency. As a result, the future of Computing and Information Technology is greatly dependent on Infrastructure as a service (IaaS), Software as a service (SaaS), and Platform as a service (PaaS), the current technological models transforming the world today.
Items that an organization’s IT / IS department should consider when an organization’s strategy calls for the use of SaaS, PaaS, or IaaS.
Delegate your assignment to our experts and they will do the rest.
The concept of IaaS has it that instead of a user making a direct purchase of hardware, they can purchase service levels that will make it possible for them to keep track of, manage, and access all remote data infrastructures that are virtual. In a situation where an organizational strategy alignment requires it to make use of the IaaS architecture, then there are a number of items that are paramount.
The company should begin by establishing a secure network connection, such as Virtual Private Networks (VPN), Wide Area Networks (WAN), and Local Area Networks (LAN), to facilitate the process of online hosting of infrastructure (Mahmood & Hill, 2011).
Strong and advanced servers and computers are also very essential to ensure reliable availability of service.
Also, sophisticated algorithms and firewalls must be considered to further enhance the security of the system.
Ways that SaaS, PaaS, and IaaS are used to reduce Total Cost of Ownership (TCO) and increase Return on Investment (ROI).
The TCO for the cloud changes owing to the fact that the cloud changes the plan of action made by the IT department. In this case, distributed computing takes the data innovation warehouse and makes it a business administration. Besides, the TCO examination is of a multidimensional nature because of the fact that a cloud can be both a distinct option for and a component of in-house IT assets. The objective is to create particular results once you shift to the cloud. It is true that the cloud reduces capital expenses. However, there is no experimental proof to show that it will reduce the collective expense of proprietorship in the long run.
Impact to the IT support personnel when an organization embarks on the strategy stated in Question 1.
The IT provides choices to control, approach, and sourcing, and it bears a versatile considered set of administrations, which clients consider as having an enhanced cost proficiency , a consistent accessibility, a boundless limit, and expanded nimbleness. For the IT department to accomplish these qualities, then it is expected to move its conventional server-driven way to help it deal with a methodology that is more administration driven.
Considerations that the organization’s management should be aware of.
The firm must keep in mind the supplier’s Service Level Agreement (SLA) to help them create a good alignment with the service provider.
The firm should also ensure that the workforce is enough and well trained to ensure successful implementation and integration of SaaS into the business activities (Vacca, 2013). Any skill gaps will make it difficult for the firm to reap maximum benefits from SaaS.
Finally, security is a very paramount consideration because cloud-related operations are exposed to countless vulnerabilities and threats and vulnerabilities (Vacca, 2013).
Security issues that could arise from this type of an infrastructure. Use at least three quality resources in this assignment.
Smoot & Tan (2011) state that network security is enhanced using advanced switches and strong firewalls in the traditional data centers. It is very important to secure networks in IaaS because communication within the system is continually increasing. When the network is not properly secured, then there might be a number of threats and vulnerabilities that are likely to compromise the company’s confidentiality (Smoot & Tan, 2011). Poor security architecture might also result in issues of reporting and eventing where teams will fire up virtual machines using self-service portals and this creates the need for an awareness of devices within the company’s infrastructure. Another security issue is related with Identity Management and Access Control (idAm) when dealing with Data and Service management issues within IaaS framework in the firm.
