Cloud computing is a type of internet based computing. It is the process of sharing large computing resources over the internet in different devices. In this system, the documents are stored on the internet instead of computer’s hardware. As a result, the user can easily access the data from anywhere.
The term cloud refers to a collection of objects that visually appear to be distinct from a distance. Cloud computing has evolved through a number of phases and shared technologies of existing models and cloud computing applications including grid and utility computing, client-server model, peer to peer, application server model, etc. However, it has come into existence since 2000.
The cloud computing system comprises three components:
Today, most of the business houses use cloud computing system in their day to day activities for the smooth functioning of their internet based services. Be it e-commerce site or multinational company or educational field, they all integrate cloud computing system to increase their work efficiency. It is, therefore, essential for students seeking cloud computing assignment help to understand its key features that lead to its excessive usability in various fields.
Cost Efficiency- Capital expenditure is converted into operational expenditure in a public cloud delivery model which reduced capital expenses. This apparently lowers barriers to entry with minimal investment for infrastructure. Few IT skills are required for implementing the cloud computing projects with usage-based pricing options.
Agility- It improves the users’ capability to expand and re-provision technological infrastructure resources.
API Accessibility to Software- It enables the system to interact with cloud software. The cloud computing systems use REST-based Application Programming Software and manage backend using big data.
Multi-tenancy-It helps to share costs and resources across the users which further result in:
Reliability- The use of multiple-repetitious sites help in making well-designed cloud computing convenient for disaster recovery and business continuity and further improves reliability.
Device and Location Independence- It allows users to access the infrastructure provided by third-party using the internet. Users can connect to it from any location.
Performance- IT experts from the service provider oversee the performance. Web services are used as the system interface for constructing architecture
Maintenance- As cloud computing applications are not required to be installed in users’ computer and can be accessed from anywhere; these applications can be easily maintained.
Productivity- Cloud computing increases the productivity by enabling multiple users to work on the same data simultaneously. It increases their time and efficiency.
Scalability- It provides the ability to scale up when the usage needs increase or scale down if resources are not being used.
It is important for students to know how cloud computing has evolved over a time and emerged in the market by major internet companies. Having a strategic understanding of all the major cloud technologies that marks the significance of cloud computing in the global market helps students plan their cloud computing assignment more precisely keeping in mind its usage in various sectors.
After this, many big companies such as Rackspace Hosting and NASA with OpenStack, IBM with IBM SmartCloud and Oracle with Oracle Cloud introduced their cloud software in cloud computing market.
Cloud computing is a type of computing which encompasses huge scalable IT-related capabilities as a service using web technologies to multiple external customers. These services are grouped into Cloud Service Models and Cloud Deployment Models.
There are three types of Cloud Models for service:
Software as a Service (SaaS)– Itis highly advanced and complex cloud model. The software is managed by a service provider which allows customers to use the applications running on cloud infrastructure to resolve their issues. These applications can be accessed from various client devices through a thin client interface or a program interface. Some of the solutions being offered under this model include web-based email, office automation suites, business intelligence, sales force automation and web conference.
Platform as a Service (PaaS)– It focuses on developing, managing and deploying customer-acquired applications using programming languages, tools, and services supported by the provider. The customer does not manage the underlying cloud infrastructure but has a control over the deployed applications and deployment tools.
Infrastructure as a Service (IaaS) –It is the fundamental block for cloud IT. Management control and user flexibility are highest in this model. It provides processing, storage, networks, and other computing resources where users are able to deploy and run software compiled with OS-based applications. It has a limited control of select networking components.
There is also Cloud Models for Deployment which is categorized into four types:
Private Cloud– It is used for one’s personal needs i.e. the cloud infrastructure is managed for a single organization. It may be operated internally or by a third-party and hosted either internally or externally. Private Cloud project with a significant level of involvement to virtualize the business environment can improve the business.
Public Cloud– Thecloud is called public when the service network is open for public use. The services under public cloud project may be free. Security considerations for services offered by service providers for the public audience may differ in public cloud than private cloud. Service providers like Amazon, Microsoft and Google own and manage infrastructure at their data center.
Community Cloud – It is primarily used for community purposes. Here infrastructure is shared between various organizations belongs to a particular community with common interests. It can be managed internally or by a third-party.
Hybrid Cloud– It is a combination of both private and public or community cloud computing that due to diverse nature offers benefits of multiple deployment models. It allows one to expand the capabilities of a cloud service by integrating it with other cloud services. Hybrid cloud helps to provide a lot of early solutions.
In recent years, cloud computing has been the driving force of business and highly applicable in almost every aspects of IT sectors from data and analytics to security and project management. Most companies are operating their applications into the cloud. There is a huge demand for the candidate with a blend of practical knowledge in data system and networking and technical skills in planning, executing and monitoring cloud solutions.
Students need to develop technical skill sets and get updated with the constant changes in the cloud technology in order to make them invaluable to companies. Today, employers are looking for the professionals who can fit the role of data scientists, cloud developers, security specialists, cloud architects, database administrators and more.
Some of the key cloud-based job roles that are in very highdemand in the cloud market sectorare described as follows:
Cloud Architects must have a strong understanding of the best ways to design and build cloud environments. They must be familiar with all the major cloud technologies available and needs to build expertise in at least one of them. This knowledge of different cloud platforms helps them to critically identify which services are best suited for any particular situation. They took over migration projects to move the companies into the cloud and responsible for disaster recovery and mitigation.
The companies that work for creating applications and infrastructure in the cloud oftenrequire cloud architects. Cloud architects can stay competitive in the market by having a cloud certification, working experience and knowledge of the latest features of cloud platforms.
Data security has always been the primary concern for the companies who possesses cloud technology. They often struggle to find the right candidates who address cloud security threat from the cyber attacks. Cloud security specialists have come to deal with all these security concerns.
They work with architects in creating engineering solutions that provide security from the starting. They assist architects in deciding where and how to store crucial data and assist in creating a secure application that limits potential exposure to important data leakage. This can be achieved by imposing identity authentication, management, and security monitoring system for the cloud environment.
