EDGE COMPUTING
OVERVIEW:
Edge computing is the
decentralised technique of processing data and executing applications closer to
the source of data generation, as opposed to depending on a centrally managed
cloud infrastructure. Edge computing brings edge devices, such as Internet of
Things (IoT) gadgets, sensors, or user gadgets, closer to computer resources,
such as processing speed, storage capacity, and networking skills.
The central cloud server receives
data from edge devices as part of the traditional cloud computing model for
processing and analysis. With the growth of IoT and the desire for low-latency
applications and real-time data processing, edge computing has emerged as a
solution to these issues.
Edge computing offers various advantages by bringing computer power closer to the edge:
Reduced latency: Edge computing
cuts down on the amount of time data must travel back and forth between devices
and the cloud by processing data locally at the edge. This is essential for
real-time or almost real-time processing applications, such as remote
monitoring, industrial automation, and autonomous cars.
Optimising bandwidth usage: Edge
computing does this by processing data locally and sending just the information
that is required to the cloud. As a result, less data must be transmitted
across the network, requiring less bandwidth and costing less money.
Increased dependability: By
minimising reliance on a central cloud infrastructure, edge computing can
increase the dependability of applications. Edge devices can carry on and carry
out crucial tasks even if the connection to the cloud is lost.
Enhanced security: By keeping
critical data localised and lowering the attack surface, edge computing can
improve security. Data breaches during transmission to the cloud can be reduced
by processing and storing data locally.
Compliance and privacy: Some data
privacy laws stipulate that data must stay inside certain geographical
restrictions. Organisations can process and store data locally using edge
computing, guaranteeing compliance with these rules.
Different architectural models,
such as fog computing, which distributes computing resources over a number of
layers between edge devices and the cloud, can be used to perform edge
computing. The deployment of edge analytics, machine learning, and artificial
intelligence (AI) capabilities is also made possible by edge computing,
allowing for quicker and more effective decision-making at the edge.
Edge may consist of the following elements:
Edge gadgets Every day, we
utilise edge computing devices like smart speakers, wearables, and phones,
which collect and process data locally while interacting with the real world.
Robots, cars, POS systems, Internet of Things (IoT) devices, and sensors can
all be edge devices if they communicate with the cloud and do local
computation.
Network edge: Edge computing can
be found on individual edge devices or a router, for example, and does not
necessitate the existence of a separate "edge network." This is just
another point on the continuum between users and the cloud when a different
network is involved, and this is where 5G may be useful. With low latency and
high cellular bandwidth provided by 5G, edge computing will have access to
incredibly powerful wireless connectivity, opening up intriguing possibilities
for projects like autonomous drones, remote telesurgery, smart city
initiatives, and much more. When putting computation on premises is too
expensive and cumbersome but great responsiveness is required, the network edge
can be especially helpful.
Regional systems are managed and internet connections are
made via on-premises infrastructure, which may comprise servers, routers,
containers, hubs, or bridges.
Edge computing enables you to
fully utilise the massive amounts of untapped data that are generated by
connected devices. You can find new business opportunities, improve operational
effectiveness, and give your consumers faster, more consistent experiences. By
analysing data locally, the best edge computing models can aid in performance
acceleration. A thoughtful approach to edge computing can assist ensure
privacy, keep workloads current in accordance with established standards, and
comply with data residency laws and regulations.
But there are difficulties in
this procedure as well. Network security issues, administrative challenges, and
latency and bandwidth constraints should all be taken into account by an
effective edge computing paradigm. A good model should enable you to:
- Manage your workloads on any number of devices and across all clouds.
- Applications should be reliably and smoothly deployed to all edge locations.
- Keep an open mind and be willing to adjust to changing circumstances.
- Increase your operational security and confidence.
cloud, edge, and fog computing
The ideas of cloud computing and fog computing are strongly
related to edge computing. Despite some similarities, these ideas are distinct
from one another and normally shouldn't be utilised in the same sentence. It's
beneficial to contrast the ideas and recognise how they differ.
Highlighting the similarities between edge, cloud, and fog
computing makes it simpler to grasp how they differ from one another: all three
ideas are related to distributed computing and place an emphasis on the actual
placement of computation and storage resources in connection to the data that
is being produced. Where those resources are placed makes a difference.
Edge:
The placement of computer and storage resources to the site where data is generated is known as edge computing. In an ideal scenario, this places compute and storage close to the data source at the network edge. For instance, to gather and analyse data generated by sensors inside the wind turbine itself, a tiny container with multiple servers and some storage might be put on top of the device. Another illustration is the placement of a small amount of computing and storage within a railway station to gather and interpret the vast amounts of sensor data from the rail traffic and track. The outcomes of any such processing can then be returned to a different data centre for manual inspection, archiving, and merging with the outcomes of other data for more extensive analytics.
Cloud:
A massive, highly scalable
deployment of compute and storage resources at one of numerous distributed
global locations is known as cloud computing. The cloud is a favoured
centralised platform for IoT deployments since cloud providers offer include a
variety of pre-packaged services for IoT operations. The closest regional cloud
facility may still be hundreds of miles from the location where data is
collected, and connections rely on the same erratic internet connectivity that
supports traditional data centres, despite the fact that cloud computing offers
more than enough resources and services to handle complex analytics. In
actuality, cloud computing serves as a replacement to existing data centres, or
perhaps as a complement to them. Centralised processing can be brought
considerably closer to a data source thanks to the cloud, but not at the
network edge.
Fog:
However, neither the cloud nor
the edge are the only options for deploying compute and storage. Even though a
cloud data centre may be too far away, strict edge computing may not be
feasible due to resource constraints, physical dispersion, or distributed
deployment. The idea of "fog computing" can be helpful in this
situation. Fog computing often takes a backwards step and places processing and
storage resources "within" the data, rather not necessarily
"at" the data. Fog computing settings can create staggering amounts
of sensor or Internet of Things (IoT) data that are spread across enormous
physical areas and are just too big to define an edge. Smart utility grids,
smart cities, and smart buildings are a few examples. Think of a "smart
city," where data is utilised to monitor, assess, and improve the city's
public transportation system, municipal services, and utilities, as well as to inform
long-term urban planning. Fog computing can run a number of fog node
installations inside the scope of the environment to gather, process, and
analyse data because a single edge deployment simply cannot handle such a load.
