Cloud Computing and Cloud Hosting

Introduction on Cloud Computing & Cloud Hosting 
The simple explanation to the word cloud computing is an environment where you can access your software from your desktop computer or laptop to an online environment and can access it from anywhere and anytime. It is a way of providing different services with the help of internet, and with the help of tools and applications available like servers, databases, software etc.

For example: Microsoft Office applications.    

The simple explanation to cloud hosting is an environment of storing your data, your files, your content to any online storage, from where you can access it anytime from anywhere. For example: Google Drive. 

What Is Cloud Computing?
In a very simple words, It is a way of providing different services with the help of internet, and with the help of tools and applications available like servers, databases, software etc. Instead of saving and keeping our data and files on a local storage device, we can use the cloud-based storage. As long as an electronic device has access to the web, it has access to the data and the software programs to run it.

Cloud computing is primarily divided into three categories which are:
  • IaaS based model (Infrastructure-as-a-Service): In the Infrastructure as a Service model, hardware resources are provided to the end users to install their applications and for the data storage.
  • PaaS based model (Platform-as-a-Service): In the Platform as a Service model, softwares, applications, databases and Operating Systems are delivered to the end users.
  • SaaS based model (Software-as-a-Service): In the Software as a Service model, third party Cloud Provider hosts the Software or Application which is delivered through a network connection.

Cloud computing allows pay-per-use, self-provisioning, workload flexibility, and much more that can avail only by choosing a Cloud computing for the organization.

Cloud Computing is deployed within three models:
  • Public Cloud: The Cloud Computing resources are owned and delivered over the Internet by a third-party service provider in this model.
  • Private Cloud: Private Cloud refers to the use of computing resources limited to one organization.
  • Hybrid Cloud: It combines the specialties of both above mentioned Public Cloud and Private Cloud.
The term Cloud hosting and Cloud Computing are very similar as both are installed off-premises and can be accessed only through a reliable and fast Internet Connection. 

Cloud Hosting
Cloud hosting is a service offered by Cloud Computing, which is best suitable for small and medium sized businesses lying in limited budget. It is a set of computing resources from a Cloud Computing provider which is then used to host data or services.
  • Cloud hosting is a Cloud delivery model based on Infrastructure-as-a-Service (IaaS) that provides virtual services deployed on the top of a Cloud Computing Infrastructure.
  • It uses resources such as storage, hardware, network, and others from a Cloud Vendor.
  • It is enabled through virtualization in which the entire computing power of a data center is made accessible to multiple users all together
  • It provides maximum scalability as much as an organization demands.
  • Cloud Hosted Solutions include Cloud Desktops, Cloud Storage, and Cloud Servers etc.

Current Cloud Computing Tendency in 2020

The Cloud Computing industry with continuous growth is arising with a number of Cloud Computing trends. The Cloud Trends that we are going to mention below are the combination of new and old practices that have changed the way the industries operate. Below are some of them:

    Internet of Things (IoT)
    Internet of Things indicates to scenarios where network connectivity and computing efficiency enhances to objects, sensors and everyday items not normally considered computers, allowing these devices to generate, exchange and consume data with minimal human intervention.

    5G Networks
    All of the IT services are expected to generate a huge amount of data that will be stored in the cloud. However, while handling this huge amounts of data, it is important that you have a reliable internet connection with great speed. LTE as an internet standard has already reached its limits, which is why the world is now looking towards 5G.

    Increase in Storage Capacity
    One of the main aspect for growth-related to cloud computing trends is the increase in storage capacity. In 2017 alone, the global cloud storage capacity stood at around 600 EB (Exabytes). We can certainly expect this to become one of the Cloud Computing Trends 2020, as the capacity is set to double to approximate 1.1 ZB (Zettabyte) by the end of 2018. Regular people are boosting these numbers, thanks to their increased sharing of personal information online via services like Google Drive and Dropbox.
    Cheaper Storage Solutions
    The Cloud Computing Industry is going through a lot of changes. Massive Growth and Cheaper Prices were two of the main Cloud Computing Trends 2017. Usually, when demand increases, the price also increases, but since there is so much competition in the market today it seems that the prices are continuing to fall; thanks to so much investment in storage capacity increase. To put this in context, at present it costs less than 10 cents to maintain 1 TB of cloud storage. This price dive has given companies the ability to offer ridiculously cheap cloud storage solutions, which is, in turn, driving the growth further.

    Server-less Cloud Computing
    Startups have been the main driver of this Cloud Trend, as it lets them indulge in early cloud adoption, for better security and easier development. Even older organizations have started replacing their existing application to take advantage of this opportunity.

Big Data and Cloud Computing – A Perfect Combination

Big Data: Big data is dealing with the enormous scale of data whereas Cloud computing is about infrastructure.
The mix of both turnout to beneficial conclusion for the organizations. Both of the technologies are in the stage of progression but their combination leverages scalable and cost-effective solution in big data analytics.

Big Data and Cloud Computing
Big data deals with massive structured, semi-structured or unstructured data to store and process it for data analysis purpose. There are five aspects of Big Data which are described through 5Vs:
  • Volume – the amount of data
  • Variety – different types of data
  • Velocity – data flow rate in the system
  • Value – the value of data based on the information contained within
  • Veracity – data confidentiality and availability

How is Big Data Related to Cloud Computing?
Cloud enables “As-a-Service" pattern by abstracting the challenges and complexity through a scalable and elastic self-service application. Big data requirement is same where distributed processing of massive data is abstracted from the end users.

There are multiple benefits of Big data analysis in Cloud:
Improved analysis
With the advancement of Cloud technology, big data analysis has become more improved causing better results. Hence, companies prefer to perform big data analysis in the Cloud. Moreover, Cloud helps to integrate data from numerous sources.

Simplified Infrastructure
Big Data analysis is a tremendous strenuous job on infrastructure as the data comes in large volumes with varying speeds, and types which traditional infrastructures usually cannot keep up with. As the Cloud computing provides flexible infrastructure, which we can scale according to the needs at the time, it is easy to manage workloads.

Lowering the cost
Both Big data and Cloud technology delivers value to organizations by reducing the ownership. The Pay-per-user model of Cloud turns CAPEX into OPEX. On the other hand, Apache cut down the licensing cost of Big data which is supposed to be cost millions to build and buy. Cloud enables customers for big data processing without large-scale big data resources. Hence, both Big Data and Cloud technology are driving the cost down for enterprise purposes and bringing value to the enterprise.

Security and Privacy
Data security and privacy are two major concerns when dealing with enterprise data. Moreover, when your application is hosted on a Cloud platform due to its open environment and limited user control security becomes a primary concern. On the other hand, being an open source application, Big data solution like Hadoop uses a lot of third-party services and infrastructure. Hence, nowadays system integrators bring in Private Cloud Solution that is Elastic and Scalable. Furthermore, it also leverages Scalable Distributed Processing.

Major Problems With Cloud Computing

Every technology comes with a baggage of some pros and cons. Similarly, cloud computing too comes with its share of issues despite being core strength of some business industries. It also can create some major problems under some rare circumstances. issues and challenges of cloud computing are characterized as ghosts in the cloud. Let us talk in brief about some real life ghosts of cloud computing.

Data Security concern

Since you are transferring your company’s important details to a third party so it is important to ensure yourself about the manageability and security system of the cloud. Multiple serious threats like virus attack and hacking of the client’s site are the biggest cloud computing data security issues. Entrepreneurs have to think on these issues before adopting cloud computing technology for their business. 

Real Time Monitoring Requirements

In some agencies, it is required to monitor their system in real time. It is compulsory term for their business that they continuously monitor and maintain their inventory system. Banks and some government agencies need to update their system in real time but cloud service providers are unable to match this requirement. This is really a big challenge for cloud services providers.

Dependency On Service Providers

For uninterrupted services and proper working it is necessary that you acquire a vendor services with proper infrastructural and technical expertise. An authorized vendor who can meet the security standards set by your company’s internal policies and government agencies. While selecting the service provider you must carefully read the service level agreement and understand their policies and terms and provision of compensation in case of any outage or lock in clauses.

Consumption Basis Services Charges

Cloud computing services are on-demand services so it is difficult to define specific cost for a particular quantity of services. These types of fluctuations and price differences make the implementation of cloud computing very difficult and complicated. It is not easy for a normal business owner to study consistent demand and fluctuations with the seasons and various events. So it is hard to budget for a service that could consume several months of budget in a few days of heavy use.
