Cloud computing can be simply described as, the on-demand delivery of IT services and resources over the internet with pay-as-you-go pricing. These IT services/resources include storage databases, servers, networking, and analytics over the internet. In cloud computing, all the data is collected and managed in a centralized location. Often in a data centre. This approach ensures security protocols to be managed properly. At the same time, allowing reliable remote access.

In simple words, assets and information are stored in a cloud, allowing authorized users to have the access to information from any location at any time. We as individuals are unintentionally surrounded by cloud computing. The domain of cloud computing is far beyond accessing files on multiple devices. Cloud computing allows users to store information from anywhere such as in Google Drive & Dropbox.

One can backup picture, videos, etc using cloud computing. Organizations of every tier and type are adapting to cloud computing. Moving ahead of conventional Business IT resources. Obvious reasons and benefits are compelling companies to look towards cloud computing. First and foremost, cloud computing banishes the needs of purchasing hardware & software, their maintenance and power management, IT experts for handling the infrastructures. Saving huge expenses. Increasing productivity and most importantly saving time.

Big cloud computing services run on a huge network across the world within secure data centres, which are continuously upgraded. Ultimately increasing the performance. Cloud providers offer a prescribed set of policies ensuring overall security. Protecting assets and information from potential security threats.

Cloud Computing Models:

There are various models of clouds. Each of them varies as per the desired requirements.

Cloud Computing Models

Public Clouds:

These clouds are owned and managed by third-party cloud providers. These provide services on servers and data storage over the internet. Public clouds are accessed by clients through allotted accounts.

Private Clouds:

These are private network services. Their usage is limited to a specific company or organization. Managing the internal data and information of the company through them.

Hybrid clouds:

These clouds are formed by combining Public and private clouds. Hybrid clouds allow flexibility, increased deployment options, and optimization of existing infrastructures.

Types of Cloud Computing:

The three principal types of cloud computing are Infrastructure as a Service, Platform as a Service, and Software as a Service. Each type of cloud provides different control functions & flexibility.

Types of Cloud Computing

Infrastructure as a Service (IaaS):

IaaS forms the building blocks for cloud services. IaaS is identical to existing conventional IT resources. Hence providing a great degree of flexibility and easily manageable.

Software as a Service (SaaS):

A thorough product that is entirely managed by the cloud provider. With Software as a Service, management and handling infrastructure isn’t the concern of the organization. It’s rather how to utilize the infrastructure.

Platform as a Service (PaaS):

PaaS removes the need for you to manage underlying infrastructures. Hence allowing you to focus on the practical deployment. Ultimately increasing efficiency.

Edge Computing- The New & Latest Revolution:

Edge computing is based on the concept of bringing computing as nearer to a source of data as possible. In simpler terms, reduced processes within the cloud. Shifting those processes in local places such as in the user’s computer, IoT device, or an edge server. It is necessary to understand the term ‘Edge’. The network edge is where the local network containing the functional device communicates with the internet. The biggest takeaway is that the network edge is geographically close to the device, unlike cloud servers.

Edge Computing- The New & Latest Revolution

Computing being done at Network’s edge reduces the amount of long distant communication. Maximizing performance, reducing cost & latency are the biggest gains of Edge computing. As we have already seen, using Edge computing reduces the usage of Bandwidth and server resources. With homes & offices getting equipped with printers, thermostats & smart cameras, etc. Managing all these devices requires significant computations to be moved towards the edge.

The biggest benefit of using Edge computing is minimizing latency. With conventional servers, every bit of information is bound to travel large distances before reaching out the desired location. That’s not the case with Edge computing as it makes the perfect usage of existing internal servers to transfer information. Edge computing finds its practical applications in the extensive chain of fields.

It can be used in monitoring assets in the field of oil and gas. Edge computing allows real-time analytics. Alerting the company in case of any breakdown. Healthcare contains various edge computing opportunities. An edge network on the hospital site could process data locally to maintain data privacy. Edge also provides right-time notifications to doctors in case of unusual patient behaviours. Apart from that, it can be utilized in traffic management, cloud gaming & Autonomous vehicles, etc.

Types of Edge Computing:

Depending upon computing resources, Edge computing can be classified into various types.

Types of Edge Computing

Cloud:

As mentioned, prior, the cloud refers to massive data centres managed by cloud providers.

Compute Edge:

Compute edge is a sort of small data center, containing racks of servers. It is generally placed in the vicinity of IoT devices. The resources in compute edge are not as vast as in the cloud. But is effective in decreasing latency and increased bandwidth.

Device Edge:

Device edge comprises of few small servers and hence has minimal computing capability. But again, the advantage lies in its close location to IoT sensors.

Sensor:

IoT sensors are the controlling devices such as security cameras, bulbs & routers, etc. They don’t have any computing ability. They are dependent on the cloud, compute edge or device edge for computation.

Head-to-Head Comparison:
