Almost everyone is in the cloud in which cloud computing challenges are numerous. We have to figure out the challenges which are to be overcome. According to the survey, almost 96% of the IT companies are using cloud computing services, whereas 92% are using the public cloud. Many organisations are running around 40% of the workload in clouds. The percentage is growing in recent years. Cloud computing is booming because more apps are likely to move into the cloud. Iaas is growing at a rapid phase which alone accounts to 36%.In spite of having concerns about cloud computing, many cloud leaders are still using it because of the numerous benefits it is offering.
Here are the few challenges faced by cloud computing:
1.Managing multi-cloud environments:
Most of the organisations are not using one cloud. From the survey of RightScale findings, it is estimated that almost 81% of all the entrepreneurs are using multi-cloud strategy. The multi-cloud environment is increasing the complexity faced by IT companies. Doing practices like training employees, doing research, actively managing vendor relationships, tooling and rethinking process.
Moving the existing application into the cloud is the most difficult task. A dimension research study found that mostly 62% of the cloud migration projects are most difficult than it is to be expected.55% exceeding their budget while 64% is taking longer than to be expected. All the migration projects are troubleshooting, time-consuming, slow migration of data and difficulty security configuration, difficulty syncing data before cutover, downtime during migration and trouble during migration tools to work properly. To overcome all these major IT challenges hiring in-house experts, set a longer project timeline, increase budget.
Many vendors like Microsoft Azure, IBM cloud, Google cloud platform, Amazon Web Services are dominating the public cloud market. That’s because of the buyer’s caution. Ensure that the services you use are unique and can be transported to other providers, and most importantly, understand the requirements. It could be that this service is not standard or there is no decent vendor replacement. Entering the cloud computing agreement is easier than leaving it.
4.Reliability of new technology:
Security threads increase because they do not know and where information is stored and processed. Usually, employers are hesitant to share organizational information with unknown service providers. This is a fact of human nature that we believe in things that are before our eyes. They think that the information stored in their offices is safer and more accessible. By using cloud computing, they fear losing control of data. They think that data is taken from them and submitted to unknown third parties. The fear of these unknown service providers must be peacefully dealt with and removed from their minds.
A major fear of cloud service providers is cyber attacks which is an operational security issue. Most of the data stored in the cloud are at a risk of cyber attack where an only limited amount of data is to be stored. Vulnerability assessment on the overall security measures of providers against external attacks is an effective way to ensure that data in the cloud is adequately protected. The high threat level is because the targets are often by malware, virtual machines and brute force attacks. Even as most cloud providers have strict security measures, cyber attacks are always looming. The high threat level is because the targets are often by malware, virtual machines and brute force attacks.
To transfer complex and intensive data over the network, you must have sufficient bandwidth. This is a major obstacle in front of small organizations, which limits them from implementing cloud technology in their business. Businesses can reduce costs on hardware but they have to spend a large amount on bandwidth. For smaller application costs it’s not a big problem but for large and complex applications it’s a major problem. For efficient cloud computing work, you have to bear high bandwidth costs.
7.Reducing the risk of threats:
Organizations must observe and examine threats very seriously. Every organization may not have enough mechanisms to reduce this type of threat. It’s very complicated to say that cloud service providers meet security standards and threat risks. These security threats and risks examine the application of cloud solutions.
8.Hacking of the brand:
Cloud providers accommodate many clients; each can be influenced by actions taken against one of them. When there is a threat coming to the main server it also affects all other clients too. Hard computing brings several main risk factors such as hacking. Some professional hackers can hack applications by breaking down firewalls efficiently and stealing sensitive information from organizations. As in the rejection of requests for server attack services that flooded providers of widely distributed computers.
Password security plays a crucial role in cloud security. Since many people are having access to cloudless security concern is there. If anyone who had knowledge about your password can access your account which you stored in the cloud. Multi-factor authentication should be employed to make sure password is protected properly particularly when the staff members leave. Access rights should be given to those who are related to username and password and it should be allocated for those who require them.
10.Management of cloud:
Cloud services can be easily changed and updated by business users. It does not involve the direct involvement of the IT department. It is the responsibility of the service provider to manage information and disseminate it throughout the organization. Many famous dramatic predictions about the impact of cloud computing. People think that traditional IT departments will be outdated and research supports the conclusion that cloud impacts tend to be more gradual and less linear. It consists of many technical challenges. So it’s difficult to manage all the functions of complex cloud computing
