Annual Cloud Services ConsumerTrends Studying and analyzing trends is essential especially for the business sector. It provides an insight about that business in the past and current situation, both domestically and globally. In addition, they enable decision makers to make better predictions about the future(Wang, 2017, p. 542). Growth of using clouds: According to the Right Scale 2017, cloud computing survey, 95% of businesses that were under study attested to using at least one cloud, 85% confirmed that they are using several clouds .Another survey which was conducted in 2018 shows by the end of 2018, almost 90% of companies will be moving their workloads to the cloud computing. Sources:(Sosinsky, 2015, p. 411) Which type of clouds has grown most?
Right Scale 2017 indicated that average organizations currently runs the majority of their workloads through the cloud whereby 32% of them use the public cloud while 43% are using the private could. However, The Statista's 2019 survey indicates that the public cloud became a top priority for many organizations in 2018 up from 28% in 2017 to 38% in 2018(Buyya, 2015, p. 295). Another surveywhich was conducted by Right scale in 2019 shows that the majority of companies (up to 84%) consider the hyper-cloud is the preferred strategy for them. This is represented by the increase in utilizing hyper-cloud from 51% in 2018 to 58% in 2019. On the other hand,companies with multiple public clouds or multiple private clouds plan at the same period have witnessed slight decline. Source:(Wang, 2017, p. 672) Cloud Computing Market Size:
The Statista's 2019 survey also indicated that cloud-computing market has continued to witness faster growth in the past decade from $58 billion in 2013 and it was expected to hit a $130 billion in 2018 while it is projected to hit $160 billion by 2020. Total Investment on Cloud: In 2018, a survey was conducted to investigate the total investments on cloud computing That the companies are planning to spend is about US $3.5M on average base. The largest Proportion of IT budget which was 30% was allocated to SaaS (48% of the total 30%),IaaS (30%) andPaaS (21%)(Bahga, 2018, p. 118). As a result, the average investment on cloud computing has witnessed a significant increase from U$ 1.62M in 2016 to U$ 2.2M in 2018.

Amazon Web Service (AWS): It is considered to the top most among all other providers who provide Infrastructure–as–a-Service “IaaS” platform. AWS works on different fields such as Internet of Things, Artificial Intelligence andanalytics. Many high profile companies utilizeAWS platform such as NASA, Expedia and Slack. Microsoft Azure: It is the main rival to AWS which offers a wide variety of options to the customers through IaaS, PaaS and SaaS. Adobe, Johnson Control and HP are examples of the companies that use Azure’s cloud services(Miller, 2014, p. 432). Google Cloud: It is a public cloud that offers a robust set of services for the customers suchasNetworking,machinelearningandsecuritytools.MainGooglecloud customers include HSBC, Bloomberg and PayPal. Advantages and disadvantages of cloud computing While it is noticeable that many of well-known organizations across the globe are busy moving to the cloud, some organizations are still hesitating to take the same move. It is clear for such companies that they have many doubts and fears about what could be the possible consequences if they take that step. Some fears that the decision makers might have include: 1.Does our IT staff have the required efficiency to deal with cloud infrastructure? 2.Moving all data and applications on the cloud could affect the bandwidth and performance(John W. Rittinghouse, 2016, p. 572). While it is an obvious that these fears arose from the lack of experience about the clouds, they can be addressed easily such that: Fear #1 treatment: Before selecting any cloud, the right thing is to ask whether they offer a team of experts to make the process of moving data and application smooth or not Fear #2 treatment: The proper solution is to hire a professional company to assess the performance of the existing network. In addition, what is the suitable capacity of data that can flow through your network.
While the field of cloud computing are witnessing qualitative leaps and noticeable progress at various levels, it has some drawbacks. In the following section, both advantages and disadvantages will be discussed thoroughly(Ransome, 2013, p. 21). Advantages: oEasy to implement; The utilization of cloud enables the users to maintain the same, together with those business processes without having any backend technicalities. The cloud is usually readily manageable through the internet and the infrastructure for the cloud allowsthe business organizations to access it much faster. oAccessibility:The cloud used in organizations allows them to access their data from any point and at any time. Due to that business organizations can greatly benefit from the exploited efficiency and productivity via the open applications. oNo additional hardware required:transferring to utilization of the cloud would directly translate that the existing organization’s in-house data center is of no use but can be retained only as a backup in case of any issue. That is the cloud providers provides data accessibility and storage on behalf of the user; thus, the user will not be required to purchase any hardware again(Sosinsky, 2015, p. 55). oReduced Cost per head:since the cloud service provider handles all the work, the end user will not need extra cost for operating an additional IT. Hence the organization will be able to gain a lot from the reduced overhead expenses for technology, which in turnenables the organizations tochannel additionalcashtowardsother core business strategies and objectives in order to maximize profits. oScaled, the organizations using cloud can be able to subtract or add resources depending on their needs. This will allow business organizations to grow as their systems performs.
oEfficient recovery:This is normally achieved because the cloud computing services delivers faster and more accurate retrieval of data and applications. Thus, with least downtime, cloud computing can provide the most effective recovery plan(Buyya, 2015, p. 192). Drawbacks of Cloud Computing Issues with the bandwidth:Majority of theclients whousescloud computing services are required effectively plan and to ensure that they does not pack a huge amountof servers , which includestheirstorage devicesinto smaller setsof data centers for effective performance of the cloud. Lack of redundancy: servers used in the cloud are never redundant nor are they backed up thus any technology failure for one reason or another has made several businesses to be worry of adopting such redundancy plans(John W. Rittinghouse, 2016, p. 619). In-house data centers still exist:Migrating to the cloud is not a guarantee of an abolishment of the internal data centers and servers. In this given scenario,the organization has to ensure that it hasmaintaineditsdatacenterstoevade instances of redundancy by backing up their data for quick recovery plans in case of any failure on the provider’s servers. Security:this is the most significant components which the clients who intends to migrate to the cloud computing have to consider.This is because the internet is the only mediumthrough which they will connect to the cloud. The entire cloud system may be prone to regular attacks, with that it is the responsibility of the provider to provide the required security features to the clients. Loss of data control:The moment a business organization decides to migrate to the cloud, the business is hence handing over all its information and all the data to the providers of cloud computing. This means those business organizations which have in-house IT professionals will no longer handle issues on their own and neither will

they have to say or control over how such data is managed in the cloud(Ransome, 2013, p. 73). Cloud Computing Security: Cloud security can be defined as a combined set of procedures, roles, polices and controls that work in parallel together to achieve the highest level of data protection, while the responsibility to provide the cloud security services depends on the cloud provider, the provider and the owner of the business should share the responsibility to implement the security processes. Importance of Cloud Security: The world of technology is witnessing a rapid growth on all various aspects. Attackers are continuously trying to develop their means and tools to be able to gain unauthorized access to their targets. Cloud computing is one of the preferred targets for the attackers [16]. For this Reason, it is necessary to have the best available security tools that the cloud providers provide(Buyya, 2015, p. 65). Major Cloud Computing Security issues: Distributed-Denial-of-Service Attacks (DDoS):They are attacks that disable the user from accessing to the cloud entirely or the user may encounter difficulties to access. Employee Negligence:Many employees use their own personal devices to access the cloud. These devices can be exploited by attackers if they have vulnerability in their protection system. As a result, the entire cloud will be vulnerable to attack. System Vulnerabilities:No matter how sophisticated the systems used to protect the clouds, they still have some critical loopholes especially against new attacks. Once these loopholes are recognized, the attackers can easily gain access to the cloud resources(Buyya, 2015, p. 73). Benefits of Cloud Computing Security:
Centralized Security: This technique insures that different devices within the cloud will be managed and protected centrally.As a result, the quality of traffic analysis and monitoring the network will be improved. Moreover, the policies and updates will be reduced accordingly. Cost Reduction: Once the user invests in the cloud security, there will be no longer need to buy security tools to protect the devices. In addition, it offers a constant 24/7 protection with almost no need to the human resources interference(Miller, 2014, p. 182). Reliability:Cloudcomputingoffersmanygreatoptionsforcustomers.Withthe availability of cloud protection measures, this user can access the cloud with high reliability regardless of when, where and which device being used.
