Effects of open-source software on the quality of software products


Open-source software has a source code that anybody can modify, test, and run. Open-source software is more reliable as many developers review it. Open-source software can have both positive and negative effects on the quality product of the software. Some of the positive results may be as follows. Giving the source code access to other individuals helps provide extra work to ensure the addition of improved features. Displaying the source code will enable more experienced developers to work on improving the standard of software. Open-source software gives an individual the flexibility to work on improving the entire software with new features. Open-source software enables experienced developers to find bugs and fix them while also working on security features.

Apart from having positive effects, open-source software has some adverse effects on the quality of software. More time is spent working on the system, which sometimes requires professionalism to get the software customized for efficiency. Sometimes an open-source community does not guarantee someone to get help in the forums. Most open source applications prefer offering support for maintenance at a cost. 

Traditional vs Modular Data Centers


Traditional data consists of servers that run continuously to keep data stored and accessible every time. Traditional data centers require careful maintenance such as regulating temperature and humidity and security to maintain high performance. In contrast, the modular data center has modules and compartments in a location that meets the company’s standards. The data has different areas designed separately, each area serving its purposes such as power load and configurations. Power supply and cooling are categorized independently in the modular data center to avoid interfering with each other. Traditional data centers have a long time of construction as compared to modular data centers. Research shows that the time taken to complete a traditional data center is more than a year due to planning, decision-making, and implementation. Modular data centers use minimum efficient time as customers wish to build data centers fast in ever-changing business requirements. 

In the design of a traditional data center, extra space and heating and cooling capability are often added to meet development and potential needs. This method helps data center growth, but at the same, there can be inefficient space and more energy bills. For modular data centers, individuals starting from scratch can start with current needs, which can then be scaled up and down regarding future demands. Unlike traditional data centers, modular centers help in standardizing designs that match companies and customers’ needs.

Advantages of modular data centers.

Modular data centers have a short period for design and implementation. The system’s structure is reasonable since it meets the current IT requirements, which favors its design. Modular data center only requires a few scaled infrastructures that make the period of deployment shorter (Delta, 2020). Unlike traditional data centers that take more than ten months, a modular data center takes two to three months. Modular data helps in the conservation of the environment and energy. With the current IT requirements, users can provide modules that are only for the required equipment, saving power energy. 

Modular data centers use a standard interface that saves the consumption of electricity. Another benefit of modular data centers is intelligent management that improves operations (Delta, 2020). Customers will benefit from the intelligent management system’s energy-saving and consumption-reduction capabilities. The aid of multiple reports achieves multi-level refined energy consumption control of data centers and explicitly places additional energy consumption points.

Disadvantages of modular centers

The proximity level is among the many disadvantages associated with modular data centers. Some data centers are located in the middle of a building increase the cost of cable and piping run through the perimeter walls. Some modules are susceptible to damage from rain and wind due to their location being outside a building.   

Network-attached storage (NAS) - central storage also helps improve security


Every company requires the safety of their data to provide their customers with a better level of service. Some businesses are faced with the challenge of storing data, especially small businesses. It may be as a result of cost options, the ease of operation, and data backup. Therefore, NAS devices become essential with the low costs for both small and big businesses. A NAS device is a network-connected storage device that enables authorized network users. It helps diverse clients store information and access them from a central area (Drager, 2019). 

NAS devices are flexible as they allow additional input to current storage. Network-attached storage in the office may compare to cloud server storage because it is faster and less expensive. 

There are various significant reasons to contemplate when implementing network-attached storage. First, NAS devices allow central file storage and easy access. Someone can access the files remotely or on a desktop at a workstation. Accessing files remotely helps in reducing costs for sending emails to yourself when asking for work. Having central storage also helps improve security for data and information as it reduces the chances of losing files. Second, having network-attached storage helps automate local cloud backup that acts as cloud servers for mobile devices. Employees can decide to either backup files via Ethernet cable or wireless means to ease data backup. Lastly, NAS reduces PC hardware cost where companies choose cheap hard drive options since they do not require much storage space.

SAN and NAS technologies are widely adopted, as they represent the main technologies for connecting professional storage devices. Most data centers, regardless of size, involving the shared use of a storage device, adopt one of two technologies. In terms of the adoption ratio between the two solutions, there is a penetration of almost over 80% of SAN averages in the case of large data centers specific to large companies, while the IT infrastructures of small companies or satellite site offices of large companies rely equally heavily on NAS solutions.

In terms of reliability, resilience, and scalability, the two solutions are comparable. The comparison in terms of costs is not exactly relevant because the solutions are complementary (Although complementary in terms of applicability, there are a number of differences between the two technologies.) I can say that the two solutions, NAS and SAN, are complementary and each responds to precise sets of functionalities imposed by the production applications in a company. These two solutions cannot be substituted between them.

Information Systems functions

 

Align the Information Systems functions of a firm with its organizational mission include starting at the top, creating a cascade of goals, promote continuous communication in the firm, and drive accountability and consistency. The IS functions should be aligned with the management team’s opinions to be successful in the organization. It must involve the executive team when deciding on the information system.

The organization’s mission involves specific goals that the firm aims to accomplish within a particular period; hence it is important to align the IS function with the organizational goals. I would make up a list with the objectives that are a priority to the firm and ensure that the IS functions contribute towards their success. Communication is crucial in maintaining employees` output in an organization (Anitha, 2014). 

Continuous communication will help maintain the consistency of the IS functions. Continuous communication will promote open communication between employees in different departments.

Reengineering versus continuous improvement

There are various implications associated with using reengineering instead of continuous improvement in systems development. Reengineering in systems development leads to greater returns on the investment made in the organization. This is because software reengineering allows the firm to modernize the system being used and deal with the technical problems, thus reducing production costs. A modernized system can easily meet the firm’s needs, takes less processing time, and improves customer service. Reengineering helps organizations make huge changes in the firm’s general performance by reducing cycle time, costs and increasing its quality of services (Grant, 2016).

The modern world requires firms to reengineer their systems for them to remain in stiff competition. Reengineering in systems development helps advertise the organization, thus boosting the competitiveness of the firm. Reengineering leads to the creation of more productive processes in the firm. Reengineering helps avoid the costs and charges associated with continuous improvement in systems development.
