Traditional IT infrastructure and cloud computing are two distinct methods of managing and delivering IT services. Traditional IT infrastructure relies on on-premise hardware and software, while cloud computing uses remotely hosted, virtualized infrastructure and services that can be accessed over the internet.

Telenet Pvt. Ltd., a Ramesh Corp. entity, has been supporting Alibaba Cloud in Nepal since 2018. As a leading IT company, Telenet manages a wide range of value-added services such as games, entertainment, mobile health services, and application development. The company also provides digital transformation consulting in business and technology.

In this blog, we will delve into the contrasts between cloud computing and traditional IT infrastructure, as well as the advantages and disadvantages of each approach.

Cloud Computing 

Cloud computing is a method of delivering IT services over the internet, where cloud service providers offer a range of services, including basic infrastructure like storage and processing power, as well as fully managed services like software as a service (SaaS) and platform as a service (PaaS). By using cloud computing, businesses can access these services on a pay-as-you-go basis, which means that they only pay for what they use. With the increasing number of businesses moving their operations to the cloud, cloud computing has become more popular in recent years. This blog will explore some of the advantages of using cloud computing.

Advantages of the cloud computing

• Scalability: Cloud computing enables businesses to easily and quickly scale their computing resources up or down as required. This means that businesses can adapt to changes in demand or unforeseen events without having to invest in new equipment or infrastructure.

• Cost Savings: Cloud computing can be more cost-effective than traditional IT infrastructure. With cloud computing, businesses only pay for the resources they use, resulting in significant savings. Furthermore, businesses can avoid the upfront expenses of purchasing and maintaining their own hardware and software.

• Flexibility: Cloud computing enables businesses to access their data and applications from anywhere with an internet connection. This means that employees can work remotely or from different locations without worrying about accessing files or applications.

• Collaboration: Cloud computing simplifies team collaboration on projects. Since files and applications are stored in the cloud, team members can access and work on them from anywhere, making it easier to share information and work together.

• Disaster Recovery: Cloud computing can assist businesses in recovering more quickly from disasters such as natural disasters, cyber attacks, or equipment failures. Because data and applications are stored in the cloud, businesses can quickly restore their operations without worrying about rebuilding their infrastructure.

• Innovation: Cloud computing enables businesses to quickly adopt new technologies and services, helping them remain competitive and take advantage of new opportunities as they arise.

• Security: While security is a potential concern with cloud computing, many cloud service providers have robust security measures in place to protect data and applications. Furthermore, because data is stored in the cloud, businesses can quickly recover from security breaches or data loss.

Traditional IT Infrastructure 

Traditional IT infrastructure still offers certain advantages in specific situations. While it has been the norm for many years, there are several disadvantages to using this approach to manage a company's computing resources.

• High Cost: One of the biggest disadvantages of traditional IT infrastructure is its high cost of ownership. Companies must purchase and maintain their hardware and software, which can be a significant expense. Additionally, they must hire and train IT staff to manage and maintain the infrastructure.

• Limited scalability: Another disadvantage is limited scalability. Traditional IT infrastructure can be difficult to scale up or down as needed. Companies must purchase new equipment or upgrade existing equipment to accommodate changes in demand, which can be time-consuming and costly.

• Limited flexibility: Additionally, traditional IT infrastructure can be limited in terms of flexibility as it is typically located on-premises. This can be a challenge for remote or distributed teams, and employees must be physically present in the office to access files and applications.

• Maintenance and upgrades: Maintenance and upgrades of traditional IT infrastructure can be time-consuming and expensive. Companies must invest in regular maintenance and upgrades to keep the infrastructure running smoothly, which can take time and resources away from other areas of the business.

• Limited disaster recovery: In the event of a disaster, traditional IT infrastructure can be difficult to recover. Companies must have a robust disaster recovery plan in place, which can be expensive and time-consuming to implement. 

• Security risks: Furthermore, traditional IT infrastructure can be vulnerable to security risks such as cyber attacks or data breaches, and companies must have robust security measures in place to protect their data and infrastructure.

However, in many cases, IT infrastructure becomes mandatory as per business requirements and compliance issues. There are several advantages to using traditional IT infrastructure, including full control over computing resources, security control, compliance with government policies, legacy applications, high performance for computationally intensive tasks, and data sovereignty compliance for companies operating in countries with strict data sovereignty laws.

In conclusion, both traditional IT infrastructure and cloud computing have their advantages and disadvantages. Although traditional IT infrastructure provides greater control and security, cloud computing offers greater flexibility and cost savings. Ultimately, the choice between the two depends on the specific needs of the business environment, priorities of individual businesses, and growth prospects concerning business and technology concerns. However, cloud computing seems to be the future trend as more reliable data centres are developed to address the disadvantages of the traditional IT infrastructure approach in the cloud computing environment, with dedicated servers and data security prospects.
