Cloud computing disadvantages

There are many Cloud computing disadvantages:

Downtime: 

This is one of the biggest disadvantages of cloud computing. Cloud computing services are internet-based services, outrages are always based on unfortunate possibilities and can occur for any reason.

No business can tolerate the impacts of an outage. Nobody accepts interruption during critical business processes. 

How to solve the downtime issue:

There are many best practices for minimizing planned downtime in a cloud environment.

• Design service by just focusing on high availability and disaster recovery in mind.Must keep in mind and generate multiple resources by cloud vendors in your infrastructure.
•  If your services do not require any failure, then try to generate multiple resources. It will protect you from falling over and save you from any discrepancies.
• You should maintain and implement a disaster recovery plan that provides the lowest possible recovery time and recovery objectives.
• To protect the risk of business interruption from the public internet, we must implement dedicated resources such as AWS Direct Connect, Partner interconnects, and Google cloud dedicated interconnect. These dedicated servers will protect and provide you with a dedicated network between you and cloud service.

 Privacy and security:

Another disadvantage of cloud computing is that, although cloud service provides security systems to save data, there is still a risk involved. When it comes to managing sensitive data, we must not forget what happened at code space and hacking of AWS EC2 console, which at the end lead to data deletion, which eventually leads to the shit down.

Of course, any cloud service provider is required to manage the software and deployment. 

However, it is the right time to weigh all the risk factors involved in security and privacy risks:

•  You must understand the shared responsibility of your cloud provider. It will help if you need to be aware of what occurs in your network and your product.
•  Implement security at a different level of deployment 
• Know who has access to your resource and service and try to limit access to the least privilege. If your employees get access to your deployment, then you would want their impact over the smallest area as soon as possible.
• Check and balance the skills of your team and make sure they are up to the task.
• Take a risk-based approach to secure the assets used in the cloud and comprehensive security to the devices.
• Implement multi-factor authentication of your account access sensitive data or system,

Vulnerability to attack

In cloud computing, all the components are online, increasing the severe attack and security breaches from time to time. Cloud computing is built as a public service, and that’s not; it is not difficult to run.

After all, no one at the cloud vendor does not get permission without access, and it takes to get started through a valid credit card.

• Make security a center bit of all IT tasks.  
• Keep alert with the latest with cloud security best practices. 
• Confirmation security plans and procedures are dependably enrolled and looked at. 
•  Proactively depict data and apply access control. 
• Use cloud associations, for example, AWS Inspector, AWS Cloud Watch, AWS Cloud Trail, and AWS Config to mechanize consistency controls. 
• Obstruct information exfiltration.  
• Join evading and reaction methodology into security works out. 
• Find independent people undertaking reviews. 
• Get rid of secret word access from accounts that don’t have to sign in to associations. 
• Survey and turn access keys and accreditations. 
•  Follow security locales and introductions to consider known assaults. 
• Apply security best practices for any open source programming that you are utilizing. 
• Once more, use encryption at whatever point and at each possible possibility. 

These practices will help your association screen for the introduction and progression of principal information, shield fundamental frameworks from assault and bargain, and  grow enlistment to foundation and information to ensure against additional dangers.

Limited access and flexibility:

Since the cloud establishment is guaranteed, supervised, and checked by the expert association, it moves little control over the customer. 

To fluctuating degrees, cloud customers may find they have less authority over the limit and execution of organizations inside a cloud-encouraged establishment. A cloud provider’s end-customer license understanding (EULA) and the board plans may constrain how customers can manage their associations. Customers hold control of their applications, data, and organizations, anyway probably won’t have a comparable level of power over their backend establishment.

Use these best practices to maintain control and flexibility:

• Consider using a cloud provider accessory to help with executing, running, and supporting cloud organizations. 
• Understand your commitments and the obligations of the cloud vendor in the regular obligation model to diminish the chance of avoidance or botch. 
• Make time to understand your cloud expert center’s essential level of help. Will this organization level meet your assistance necessities? Most cloud providers offer additional assistance levels a long way past the basic assistance for an additional cost. 
• Guarantee you fathom the SLA concerning the structure and organizations you will use and how that will influence your concurrences with your customers.

Vendor lock-in

Vendor lock-in is another evident impediment of dispersed processing. Basic trading between cloud organizations is a help that hasn’t yet completely created, and affiliations may believe that its difficult to move their organizations beginning with one vendor then onto the following. Differences between dealer stages may make difficulties in migrating from one cloud stage to the following, which could contrast with additional costs and plan complexities. Openings or deals made during migration could, in like manner, open your data to additional security and assurance shortcomings.

• Plan considering cloud configuration best practices. All cloud organizations give the event to improve openness and execution, decouple layers, and lessening execution bottlenecks. If you have gathered your organizations using cloud designing accepted procedures, you are more disinclined to have issues porting beginning with one cloud stage then onto the following. 
• Properly understand what your shippers are offering to help keep up key good ways from lock-in challenges. 
• Use a multi-cloud technique to avoid vendor lock-in. While this may add both unforeseen development and multifaceted operational nature to your associations, it shouldn’t be a significant issue. Getting ready can help plan gatherings to the organizer and select best-fit organizations and developments. 
•  Work in flexibility as an issue of the method when arranging applications to ensure adaptability now and later on. 
• Amass your applications with organizations that offer cloud-first focal points, for instance, detachment and movability of microservices and code. Think holders and Kubernetes

 Cost concern:

Grasping cloud courses of action bringing things down a peg and for flashing errands can be viewed as being exorbitant. In any case, the principle appropriated processing advantage is the extent that IT costs venture reserves. Pay-all the more just as expenses emerge cloud organizations can give more prominent versatility and lower hardware costs, anyway the overall retail cost could end up being higher than you have foreseen. Until you verify what will turn out best for you, it’s a brilliant idea to attempt various things with an arrangement of commitments. You may similarly use the cost number crunchers made open by providers like Amazon Web Services and Google Cloud Platform.

Take the necessary steps not to over game plan your organizations, yet rather explore using auto-scaling organizations. 

Best Solution to reduce cost ratio:

• Assurance you have the choice to scale back similarly as UP. 
• Pre-pay and adventure spared cases if you have a known least usage. 
• Modernize the cycle to start/stop your cases to put aside money when they are not being used. 
•  Make alerts to follow cloud spending.

Conclude:

Various affiliations benefit from the deftness, scale, and pay-per-use charging that cloud organizations offer. Regardless, similarly as with any establishment organization, the sensibility of disseminated figuring for your specific use case should be overviewed in a peril based evaluation. Work truly to form for investigation and planning to perceive how the cloud will impact your business.
