If you want to survive in the digital world or provide any types of digital services, you will have to start using cloud services. First of all, you need to understand the advantages and disadvantages of cloud computing and how to overcome these disadvantages. Although cloud computing is the latest IT buzzword of the entire organization, you should never enter in a hurry without preparing. In this article, we will discuss the advantages and disadvantages of cloud computing, as well as some best practical methods.

　　Cloud computing type

　　Before exploring the advantages and disadvantages of cloud computing, remember that cloud computing includes three different areas:

　　IaaS -infrastructure is service

　　PaaS -platform is service

　　SaaS -Software is service

　　The advantage of cloud computing

　　1. Save cost

　　In terms of cutting expenses, cloud computing has both advantages and disadvantages. The most obvious disadvantage is that the cost of implementing cloud computing services for the first time may be quite high. However, after the initial cost estimation, cloud computing can help companies reduce some expenses in the long run.

　　Another advantage is that most cloud computing services are now collected -you only need to pay for the functions and data storage you use.

　　2. Reliability

　　Most cloud computing service providers guarantee all -weather assistance. When you choose cloud computing, all technical issues related to service are handled by cloud service providers. In the case of disaster, even if the host server fails, the data can easily transition to other available servers. Cloud service providers comply with the service level agreement (SLA) to ensure that it will assist your business in time.

　　3. Strategic advantage

　　With the intensification of competition between enterprises, you need to implement the latest technology and applications to catch up with other people. Installing and maintaining new software will spend a lot of money. Through cloud computing, you will have the opportunity to obtain all the latest applications and infrastructure without actually investing in software installation and maintenance.

　　4. Security

　　With the advancement of technology, each cloud service provider provides more advanced security functions for their customers and provides comprehensive backup and recovery. The key is to encrypt all data transmission and stored in the database through the network. Because traditional internal systems may have high proportion of data theft, cloud services will be more effective and reliable than traditional internal systems. A study by RapidScale shows that 94%of companies have discovered major security improvements inside after turning to cloud computing.

　　The disadvantage of cloud computing

　　1. Discounting period

　　Tortoring has led to customer loss, data failure and income loss. Therefore, when it comes to the advantages and disadvantages of cloud computing, the stop time is ranked first for most companies.

　　Since the cloud computing system is based on the Internet, there is no way to avoid stopping time. In addition, if you are in a place without a network, you will be unable to access data, software or applications on the cloud.

　　No organization can be avoided. On August 2020, Google suffered a large -scale power outage that lasted more than an hour. This became one of the most watched topics last year, and eventually caused the panic wave of companies around the world.

　　Here are some of the best ways you can follow to reduce stop time.

　　Consider multi -regional deployment to ensure business continuity

　　Determine a disaster recovery plan with the lowest recovery time and the goal of recovery point

　　Consider disaster recovery when designing all services

　　2. Supplier lock

　　When we discuss the advantages and disadvantages of cloud computing, the supplier lock is another first consideration. Although most cloud computing service providers guarantee that integrating business demand with cloud computing is an easy task, it is still a huge problem to break away and transfer to other suppliers. Running well on one platform may not be compatible with another platform. The transition may bring risks, and this change may not be flexible due to synchronization and support.

　　Here are some of the best practices you can follow to reduce dependence on a single supplier.

　　Cloudy strategy

　　When designing applications, improve flexibility to ensure future portability

　　To accurately understand the products sold by cloud service providers to avoid being locked

　　3. Limited control and flexibility

　　Because cloud service providers can manage and monitor the entire cloud infrastructure, most companies have small control over their data. The end user license agreement (EULA) and management policies may be different between different service providers. The most common situation is that it gives the smallest control to customers, and their access rights are limited to applications, tools and data loaded on the server. Customers may not be able to access key management services. The worst case is that they restrict the deployment of customers.

　　Here are some of the best practical methods you can follow to maintain control and flexibility.

　　Understand the responsibilities of the cloud service provider in the contract and reduce the chance of errors

　　Understand the basic & advanced support level of cloud service providers

　　Understand the SLA of the cloud infrastructure; understand how it will affect your agreement with your customer

　　4. Security

　　It is worth noting that when talking about the safety of cloud services, there are contradictory arguments. In terms of storage company data, cloud computing has both advantages and disadvantages. The most obvious disadvantage is that data is easily attacked by network attacks when it is stored in the cloud.
