All About Cloud Computing !!

A Small Guide on Cloud Computing.

Cloud computing can be understood as the outsourcing of storage data, applications, information, and its processing. The accessibility to applications and files is independent of a local server or system and data can be retrieved at any time so long as there is an internet connection

Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS) are the three broad categories of cloud-hosted services. These services are user-oriented in the sense that the provider manages these services according to the requirement of the user.

Amazon Web Services, Microsoft Azure, Google Cloud Platform and IBM are the dominant cloud services providers in the market.

Types of Cloud Computing

Cloud services are deployed in three ways. It is a categorization that allows a particular business to recognize the ideal service deployment for itself according to its requirements.

Public Cloud

A third-party cloud service provider operates and owns the public cloud. The infrastructure and in turn the software are also owned and managed by the cloud service provider. The services in the form of storage and servers are delivered by the cloud provider.

Private Cloud

Cloud services that are exclusive to a singular organization or business are understood as a private cloud. The infrastructure and services are handled on a private network and are usually situated at the various data centers of the firm. Third-party service providers can also be responsible to host private cloud services for a particular organization.

Hybrid Cloud

Hybrid clouds as the same suggest comprise of both the public and private cloud. The private and public cloud exchange data and are bound by technology that permits such exchange of applications and resources. Hybrid cloud is flexible and optimal to security, infrastructure, and compliance.

Uses of Cloud Computing

Cloud computing is relevant even in the most basic of activities such as emails, documents, tv streaming, music, etc.

It has various uses that are of value to organizations be it small scale or otherwise.

Create cloud native applications

DevOps, API driven communication,  containers, microservices architecture and Kubernates are cloud native technologies and ways that allow ease in the scalability, deployment and building of applications.

Test and Build Applications

Due to ease of scalability of cloud infrastructure, cloud had become effective in the reduction of time and cost in application development.

Analyse Data

Data analysis can become effective by the unification of data across servers, locations, teams. Also the use of machine learning and artificial intelligence can be effective in deploying statistical techniques and approaches that can provide an insightful account for improved analysis.

Deliver Software on Demand

Updates on softwares and their latest versions can be offered easily with the on demand software service on cloud that is Software as a Service (SaaS).

Stream audio and video

Cloud allows accessibility to audio and video connection to the audience with global distribution.

Store backup recover data

Data protection can be efficiently ensured through cloud since one can easily transfer data to a remote storage system that is accessible across servers and on any system.

Embed intelligence

Cloud models that are effective and intelligent can be used to create greater transparency amongst customers and offer them with useful insight from the data.

Benefits of Cloud Computing

Cloud computing has eliminated various aspects of businesses such as large servers, data storage devices, information loss, duplicate versions etc. that demanded great time and cost. Cloud with its various benefits has allowed a diversion of that cost and time into greater productivity.

Security

Cloud Computing ensures the security of stored data. Since cloud computing allows accessibility from any system the data storage is independent of server collapses and disturbances.

Boosts speed and agility

The business conditions are undergoing rapid change and the conventional IT approaches are ineffective in meeting the demands. Therefore the speed and agility that cloud offers make it far more valuable to firms. It is also the reason why it is being adopted at such a large scale.

Multitenant

Applications and portals that are personalised become accessible to multiple users at once. This is an expansive outreach for business opportunities.

Allows application resilience

Businesses can’t afford an infrastructure failure due to the digital nature of the enterprises. The availability of applications has to be ensured and that is ineffective due to the lack of resilience of the on-premises applications. Cloud offers easy accessibility to infrastructure resources and thereby enhances the resilience of applications.

Cost-Effectiveness

Any business set up on cloud would be inherently cost-efficient since the computing resources in the cloud are derived from any of the different models of cloud computing. The high scalability allows better management.

Software Updates

It is comparatively easier to make software updates to cloud services than it is to do so with an actual physical server system. These updates include security updates that are necessary for the protection of the stored data.

Control and accessibility

Cloud ensures transparency of the data being shared and thereby greater control on its accessibility. Its platform-neutral attribute allows accessibility on any device and business continuity.

Types of Cloud Service Models

Infrastructure as a Service (IaaS)

The necessary infrastructure essential to cloud hosting is addressed in this model. The servers can be either physical or virtual for the launch of a platform. IaaS is common amongst all small medium or large scale firms due to its cost-efficient nature. The firms pay according to their service requirements a select the infrastructure accordingly.

Platform as a Service (PaaS)

A software stack is offered along with the infrastructure by the service provider and the hosted software on the system is used for development work.

It is effective for the development of web applications according to their business requirements. It can be further categorized on the basis of the source whether open or closed and also whether it is mobile compatible. Its abilities that surpass the conventional solutions allows it be an experimental and potent solution for businesses.

Software as a Service (SaaS)

The service provider hosts the application to deliver software over a network that is eventually accessed by the client via the net. It is rather common and most web software is SaaS.

Top Cloud Computing Skills

Cloud Security

Cloud computing security overlaps with IT security in its functionalities such as protection against data leakage and omission.

The data centers of the service providers are the repository of data protection. Self-governed audits are made useful to determine the effectiveness of the internal procedures that manage the security of the stored data.

The Cloud security certification such as the CCSK

extends to software development security, asset security and Identity and Access Management.

Machine Learning and Artificial Intelligence

Machine Learning and Artificial Intelligence are expansive programs that use data for themselves after gaining access and deploying statistical methods.

Microsoft Azure and Amazon Web Services are platforms that do offer Machine Learning tools. While they may seem rather minimal, the technologies are gaining immediacy to cloud computing.

Serverless Architecture

Serverless Architecture or Function as a Service (FaaS) replaces the requirement of infrastructure for communication or tracking an application. The software form is scalable and can be easily upgraded. Software servers and hardware management are no more essential and thereby the architecture ends up being cost-efficient. It also enables easy migration of applications amongst vendors.

Automation

Automation, as the name suggests, allows the possibility of achieving a task without human resource. Third-party services use an identical set of tools to diagonally automate numerous platforms.

Cloud computing Skill gap.

It is no surprise that most IT professionals are not up to the demands of a cloud-based enterprise and the skill gap that is observed is considerable.

This skill gap can be minimized if job seekers situate themselves in the cloud solution architecture, design, infrastructure, analysis, optimization of business processes, etc. according to their skill sets and its potential in these fields.

Building a career in Cloud Computing.

While technical expertise and conceptual knowledge are necessary there are other actions that can be undertaken in order to situate oneself in the field. 

For instance, hands-on experience and field, related knowledge is of value as it increases the demand of the cloud professionals in the market. It would also be advisable to remain updated with the latest technological advancements that are becoming relevant to cloud computing since the field is rapidly growing.

At last cloud, certifications are of great value to get a kick start in the field. AWS, for instance, offers various certifications on particular aspects of the cloud.

The recent growth in public cloud market makes it a profitable career option that would only witness growth in the coming years.
