Computer networking is the backbone of modern enterprise computing. It enables businesses to communicate, collaborate, and access information across different locations and devices. However, computer networking is not a static or fixed phenomenon. It evolves and adapts to changing technologies and demands. In this blog post, we will explore how computer networking has changed, what is changing, and what it means for you as an IT professional.
Introduction
We are on the verge of a major shift in computer networking. For the past 20 years, most businesses have relied on a traditional hub-and-spoke model for their network infrastructure. In this model, a central server or data center acts as the hub, and the various branches or offices act as the spokes. The hub provides the core services and applications, such as email, file storage, or CRM, and the spokes connect to the hub via dedicated links, such as VPNs or MPLS.
However, this model is being challenged by the rise of cloud computing. Cloud computing is the delivery of computing services over the internet, rather than on-premises. Cloud computing allows businesses to access a variety of services and applications, such as software, platforms, or infrastructure, from anywhere, anytime, and on any device. Cloud computing also offers benefits such as scalability, flexibility, and cost-efficiency.
Cloud computing has begun to change the way businesses use and consume network resources, starting with end-user adoption. More and more end-users are opting for cloud-based solutions, such as Google Workspace, Dropbox, or Zoom, rather than traditional on-premises solutions, such as Microsoft Office, SharePoint, or Skype. This creates a new demand for network bandwidth, performance, and security, as well as a new challenge for network management and control.
Pros and Cons of Cloud Computing Services
As cloud computing becomes more prevalent and popular, businesses are also considering migrating their core services and applications to the cloud. Some businesses have already made the leap, while others are still weighing the pros and cons.
One of the early adopters of cloud computing was Salesforce, a leading CRM provider. Salesforce pioneered the concept of software as a service (SaaS), which allows customers to access its software via the internet, rather than installing it on their own servers. Salesforce has been successful in attracting and retaining customers with its cloud-based CRM solution, which offers features such as automation, analytics, and integration.
An example of a cloud computing player is Microsoft, which offers its Office 365 suite as a cloud-based service. Office 365 includes familiar applications such as Word, Excel, and PowerPoint, as well as cloud-based applications such as OneDrive, Teams, and SharePoint. Office 365 allows customers to access and edit their documents, collaborate with their colleagues, and communicate with their clients, from any device and location.
However, not all businesses are ready or willing to embrace cloud computing. Some businesses have invested heavily in their legacy infrastructure and are reluctant to abandon or replace it. Some businesses also have strict usage guidelines and policies that prevent them from using external or third-party services. Some businesses also have concerns about the security and privacy of their data and applications in the cloud.
These concerns are shared by many networking and security professionals, who are responsible for ensuring the smooth and safe operation of the network. Cloud computing poses a new set of challenges for these professionals, such as:
- How to monitor and manage the network traffic and performance across multiple cloud providers and locations?
- How to secure and protect the network perimeter and endpoints from external threats and attacks?
- How to comply with the regulatory and legal requirements and standards for data protection and privacy?
These challenges require new skills, tools, and strategies for networking and security professionals, as well as a new mindset and attitude.
Computer Networking in Context: Now, Then and For the Future
To understand the current and future trends in computer networking, it is helpful to look back at the history and evolution of computer networking technologies. Computer networking has gone through several phases and transitions, each with its own characteristics and implications.
The first phase of computer networking was the era of dumb terminals and mainframes. In this phase, the mainframe was the central and powerful computer that provided all the computing resources and services, and the terminals were the simple and passive devices that connected to the mainframe via wires. The terminals had no processing or storage capabilities of their own, and relied entirely on the mainframe for their functionality.
The second phase of computer networking was the era of dial-up and personal computers. In this phase, the personal computer became the dominant and popular device for computing, and the dial-up was the common and affordable method for connecting to the internet. The personal computer had its own processing and storage capabilities, and could run various applications and programs. The dial-up allowed the personal computer to access the internet via a phone line, but at a slow and limited speed.
The third phase of computer networking was the era of LANs/WANs and servers. In this phase, the local area network (LAN) and the wide area network (WAN) became the standard and prevalent models for network infrastructure. The LAN was a network of computers and devices within a small geographic area, such as an office or a building, and the WAN was a network of LANs across a large geographic area, such as a country or a continent. The server was a specialized computer that provided specific services and applications to the network, such as file sharing, email, or web hosting.
The fourth phase of computer networking was the era of Wi-Fi and mobile devices. In this phase, the Wi-Fi and mobile devices became the dominant and popular technologies for network connectivity and computing. The Wi-Fi was a wireless technology that allowed devices to connect to the internet without wires or cables, and the mobile device was a portable and powerful device that could perform various functions, such as phone, camera, or GPS. The Wi-Fi and the mobile device enabled users to access the internet and the cloud from anywhere, anytime, and on any device.
The fifth phase of computer networking is the era of cloud computing and cloud-based solutions. In this phase, the cloud computing and the cloud-based solution are the emerging and disruptive technologies for network infrastructure and computing. Cloud computing is the delivery of computing services over the internet, rather than on-premises, and the cloud-based solution is the software, platform, or infrastructure that is hosted and accessed via the cloud. The cloud computing and the cloud-based solution offer benefits such as scalability, flexibility, and cost-efficiency, as well as challenges such as security, privacy, and control.
However, cloud computing is not the end of the story. Computer networking is still evolving and adapting to new technologies and demands. Some of the emerging technologies that are expected to shape the future of computer networking are:
- Blockchain: Blockchain is a distributed and decentralized ledger that records and verifies transactions without the need for a central authority or intermediary. Blockchain can enable new applications and services, such as smart contracts, digital currencies, or supply chain management, that require trust, transparency, and security.
- 5G: 5G is the fifth generation of mobile network technology that promises to deliver faster and more reliable data transmission, as well as support more devices and applications, such as the Internet of Things (IoT), augmented reality (AR), or virtual reality (VR). 5G can enable new experiences and opportunities, such as autonomous vehicles, telemedicine, or smart cities, that require high bandwidth, low latency, and high availability.
- Edge Computing: Edge computing is the processing and storage of data closer to the source or the user, rather than in the cloud or the data center. Edge computing can reduce the network congestion and latency, as well as improve the security and privacy of data and applications. Edge computing can enable new scenarios and solutions, such as real-time analytics, machine learning, or video streaming, that require fast and local processing and storage.
These technologies are not mutually exclusive, but rather complementary and interdependent. They can work together to create a more efficient, effective, and innovative network infrastructure and computing environment.
One of the interesting aspects of computer networking is the cyclical nature of trends in infrastructure. Computer networking tends to alternate between wired and non-wired, and between centralized and decentralized, models. For example, the mainframe-terminal model was a wired and centralized model, the personal computer-dial-up model was a non-wired and decentralized model, the server-LAN/WAN model was a wired and centralized model, the mobile device-Wi-Fi model was a non-wired and decentralized model, and the cloud computing-cloud-based solution model is a non-wired and centralized model.
This suggests that computer networking is not a linear or one-way progression, but rather a dynamic and adaptive process. Computer networking is constantly balancing and optimizing the trade-offs and benefits of different models, depending on the technologies and demands of the time.
