Cloud computing has suddenly seen a spike in employment opportunities around the planet with tech monsters like Amazon, Google, and Microsoft recruiting people for their cloud infrastructure. Before the onset of cloud computing, companies and businesses needed to set up their own data centers, allocate resources and other IT professionals thereby increasing the expense. The fast development of the cloud has led to more flexibility, cost-cutting, and versatility.
The Cloud Computing market is an untouched high with the current market size at USD 371.4 billion and is expected to grow up to USD 832.1 billion by 2025! It's quickly evolving and step by step realizing its business value alongside pulling in more and more researchers, researchers, computer scientists, and practitioners. Cloud computing is certainly not a single subject however an arrangement of different techniques which together constitute the cloud. Below are 10 the most demanded research themes in the field of cloud computing:
1. Big Data
Big data refers to the large measures of data produced by different programs in a very brief length of time. It is quite cumbersome to store such huge and voluminous measures of data in organization run data centers. Likewise, acquiring experiences from this data becomes a tedious undertaking and takes a ton of time to run and provide results, therefore cloud is the best alternative. All the data can be pushed onto the cloud without the need for actual storage devices that are to be managed and secured. Additionally, some well known public clouds provide comprehensive big data stages to transform data into actionable bits of knowledge.
2. DevOps
DevOps is a blend of two terms, Development and Operations. It has led to Continuous Delivery, Integration, and Deployment and therefore reducing boundaries between the development team and the operations team. Heavy applications and software need elaborate and complex tech stacks that demand extensive work to develop and configure which can easily be eliminated by cloud computing. It offers a wide range of tools and technologies to build, test, and deploy applications with a few minutes and a single click. They can be customized as per the client requirements and can be discarded when not being used hence making the process seamless and cost-efficient for development teams.
3. Cloud Cryptography
Data in the cloud is needed to be protected and secured from foreign assaults and breaches. To achieve this, cryptography in the cloud is a widely used technique to secure data present in the cloud. It permits users and clients to easily and reliably access the shared cloud services since all the data is secured utilizing either the encryption techniques or by utilizing the concept of the private key. It can make the plain text unreadable and limits the view of the data being transferred. Best cloud cryptographic security techniques are the ones that don't compromise the speed of data transfer and provide security without delaying the exchange of sensitive data.
4. Cloud Load Balancing
It refers to parting and dispersing the approaching burden to the server from different sources. It permits companies and associations to govern and supervise outstanding task at hand demands or application demands by redistributing, reallocating, and administering resources between different computers, networks, or servers. Cloud load adjusting encompasses holding the course of traffic and demands that exist over the Internet. This reduces the problem of sudden outages, results in an improvement in overall performance, has rare chances of server crashes, and furthermore provides an advanced level of security. Cloud-based servers ranches can achieve more precise versatility and accessibility utilizing the server load adjusting mechanism. Due to this, the outstanding task at hand demands can be easily distributed and controlled.
5. Mobile Cloud Computing
It is a mixture of cloud computing, mobile computing, and wireless network to provide services, for example, seamless and bountiful computational resources to mobile users, network operators, and cloud computing professionals. The handheld device is the console and all the processing and data storage takes place outside the actual mobile device. Some advantages of utilizing mobile cloud computing are that there is no need for expensive hardware, battery life is longer, extended data storage limit and processing power improved synchronization of data and high accessibility due to "store in one place, accessible from anywhere". The integration and security aspects are taken care of by the backend that enables backing to an abundance of access methods.
6. Green Cloud Computing
The significant challenge in the cloud is the usage of energy-efficient and hence develop economically friendly cloud computing solutions. Data centers that include servers, cables, climate control systems, networks, etc. in large numbers consume a great deal of power and release enormous quantities of Carbon Dioxide in the atmosphere. Green Cloud Computing focuses on making virtual data centers and servers to be more environmentally friendly and energy-efficient. Cloud resources often consume such a lot of power and energy leading to a shortage of energy and affecting the worldwide climate. Green cloud computing provides solutions to make such resources more energy efficient and to reduce operational expenses. This turns on power management, virtualization of servers and data centers, recycling huge e-waste, and environmental manageability.
7. Edge Computing
It is the advancement and a considerably more efficient type of Cloud computing with the idea that the data is processed nearer to the source. Edge Computing states that the entirety of the calculation will be carried out at the edge of the network itself rather than on a centrally managed stage or the data warehouses. Edge computing distributes different data processing techniques and mechanisms across different positions. This makes the data deliverable to the nearest node and the processing at the edge. This additionally increases the security of the data since it is closer to the source and eliminates late response time and latency without affecting productivity.
8. Containerization
Containerization in cloud computing is a procedure to get operating system virtualization. The user can work with a program and its dependencies using remote resource procedures. The container in cloud computing is used to build blocks, which help in delivering operational effectiveness, version control, developer productivity, and environmental security. The infrastructure is upgraded since it provides extra power over the granular activities over the resources. The usage of containers in online services helps storage with cloud computing data security, elasticity, and accessibility. Containers provide certain advantages, for example, a steady runtime environment, the capacity to run practically anywhere, and the low overhead compared to virtual machines.
9. Cloud Deployment Model
There are four primary cloud deployment models namely open cloud, private cloud, mixture cloud, and local area cloud. Each deployment model is defined as per the area of the infrastructure. The public cloud permits systems and services to be easily accessible to the general public. Public cloud could likewise be less reliable since it is open to everyone e.g. Email. A private cloud permits systems and services to be accessible inside an association with no access to outsiders. It offers better security due to its access restrictions. Half and the half cloud is a mixture of private and public clouds with the basic activities being performed utilizing private cloud and non-basic activities being performed utilizing the public cloud. Local area cloud permits systems and services to be accessible by a gathering of an association.
10. Cloud Security
Since the number of companies and associations utilizing cloud computing is increasing at a fast rate, the security of the cloud is a significant concern. Cloud computing security detects and addresses every physical and intelligent security issue that comes across all the varied service models of code, stage, and infrastructure. It collectively addresses these services, however, these services are delivered in units, that is, the general population, private, or crossover delivery model. Security in the cloud protects the data from any leakage or outpouring, theft, catastrophe, and removal. With the help of tokenization, Virtual Private Networks, and firewalls data can be secured.
