Overview
We are heading towards hyper-connected 5G era. The number of 5G connections will reach 1.4 billion by 2025 accounting for 15% of the global mobile industry. At the same time, the number of global IoT connections will triple to 25 billion with global IoT revenue quadrupling to $1.1 trillion by 2025.
With IoT, AI & ML gaining wider adoption and the rapid increase in the number of smart devices that are redefining our day-to-day activities; operational simplicity and efficiency have become the top priority to address the needs of the data-driven future.
Inevitable Need for Reinvention
The enterprise data centres have gone through waves of disruption and transformation over the past couple of decades. While hardware is the single strong enabler of any system, beyond a point it also becomes a bottleneck, especially when a system has to be realigned to the changing business demands. With time, monolithic systems – tied to their hardware, become unwieldy and too large to deal with.
The core philosophy of cloud-native is about scalability, speed, agility and security. Therefore, the systems need to be freed from the shackles to make them agile and scalable. The web-scale journey is not just about adopting new technologies for the sake of it. It is an intrinsic shift from the traditional monolithic systems to lean microservice architecture.
How to Scale Up & Accelerate Towards Digital Future?
The web-scale model provides the flexibility, resiliency and on-demand infrastructure and it has become a growing model for organisations to adopt in their journey towards the digital future. The global web-scale IT market is expected to grow from about $200 million in 2016 to $640 million by 2022 with an estimated CAGR of 17%.
What are the Benefits of Web-Scale?
- Increases the scale of operations
- Accelerates the pace of change
- Minimises the cost of change
- Increases the number of teams while enabling them to deliver value in parallel and independent of each other
- Utilises core business capabilities and deliver value faster.
There are different stages in the web-scale journey. Web-scale does not refer to any particular technology or system, but is rather a transformative architectural approach to deploying and managing data centres. For an infrastructure solution to be considered as web-scale, it is essential for both the data fabric and control fabric to follow web-scale principles.
Until recently, web-scale IT was widely adopted by a handful of large scale internet companies. But now, with changing market dynamics driven by data-centric digital transformation impacting all the sectors, almost all the businesses are facing the same challenges as the internet companies. This, in turn, is driving the demand for agility and scalability in IT services to launch innovative offerings and monetise the digital services in the market.

FAQs
What is WiFi?
Put simply, WiFi is a technology that uses radio waves to create a wireless network through which devices like mobile phones, computers, printers, etc., connect to the internet. A wireless router is needed to establish a WiFi hotspot that people in its vicinity may use to access internet services. You’re sure to have encountered such a WiFi hotspot in houses, offices, restaurants, etc.
To get a little more technical, WiFi works by enabling a Wireless Local Area Network or WLAN that allows devices connected to it to exchange signals with the internet via a router. The frequencies of these signals are either 2.4 GHz or 5 GHz bandwidths. These frequencies are much higher than those transmitted to or by radios, mobile phones, and televisions since WiFi signals need to carry significantly higher amounts of data. The networking standards are variants of 802.11, of which there are several (802.11a, 802.11b, 801.11g, etc.).
What is an Optical Fibre Cable?
An optical fibre cable is a cable type that has a few to hundreds of optical fibres bundled together within a protective plastic coating. They help carry digital data in the form of light pulses across large distances at faster speeds. For this, they need to be installed or deployed either underground or aerially. Standalone fibres cannot be buried or hanged so fibres are bunched together as cables for the transmission of data.
This is done to protect the fibre from stress, moisture, temperature changes and other externalities. There are three main components of a optical fibre cable, core (It carries the light and is made of pure silicon dioxide (SiO2) with dopants such as germania, phosphorous pentoxide, or alumina to raise the refractive index; Typical glass cores range from as small as 3.7um up to 200um), Cladding (Cladding surrounds the core and has a lower refractive index than the core, it is also made from the same material as the core; 1% refractive index difference is maintained between the core and cladding; Two commonly used diameters are 125µm and 140µm) and Coating (Protective layer that absorbs shocks, physical damage and moisture; The outside diameter of the coating is typically either 250µm or 500µm; Commonly used material for coatings are acrylate,Silicone, carbon, and polyimide).
An optical fibre cable is made up of the following components: Optical fibres – ranging from one to many. Buffer tubes (with different settings), for protection and cushioning of the fibre. Water protection in the tubes – wet or dry. A central strength member (CSM) is the backbone of all cables. Armoured tapes for stranding to bunch the buffer tubes and strength members together. Sheathing or final covering to provide further protection.
The five main reasons that make this technology innovation disruptive are fast communication speed, infinite bandwidth & capacity, low interference, high tensile strength and secure communication. The major usescases of optical fibre cables include intenet connectivity, computer networking, surgery & dentistry, automotive industry, telephony, lighting & decorations, mechanical inspections, cable television, military applications and space.
