4 Best Cloud Deployment models

Public cloud

Advantages:

• Hassle-free infrastructure management

  A third party runs the cloud infrastructure therefore you don’t need to develop and maintain the infrastructure as the service provider does it for you. In addition, the infrastructure setup and use are not too complicated.

• High scalability

  Public clouds come with auto-scaling features. As a result of this, the workload will be balanced accordingly and you will be able to avoid downtime and crashes.

• Reduced costs

  There is no need to dedicate a person to maintain the system as a third party provides the Public cloud services. The cost of bandwidth, hardware, and application are the responsibility of the provider. You only have to pay for what you use.

• 24/7 uptime The extensive network of your provider’s servers ensures your infrastructure is constantly available and has improved operation time.

  
  

  Disadvantages:

  
  

• No control With the use of Public Cloud, you will be sharing the same infrastructure with other customers. The users have no control over it and the maintenance and the management are entirely taken care of by the service provider.

• Data security and privacy issues Although access to data is easy, a public deployment model deprives users of knowing where their information is kept and who has access to it.

• Limited customization Inability to satisfy more complex requirements due to standardized service options

Private cloud

Advantages:

• Flexible development

  Using a Private platform means that there are no compatibility issues for the applications

• Higher performance Since there is no need to share resources with other users there is a significant rate of transfer therefore private cloud provides a higher level of performance. Since the private cloud is located behind a firewall there are fewer chances of internet security risks.

• High security and privacy Private cloud make sure that there is an extra level of security making it ideal for big organizations with confidential and sensitive information. The data is in a protected environment that is allocated just for the user’s business.

• Control is the best positive feature of the Private Cloud. Because the hardware is available onsite the company can control data. Complete oversight of the data is done by the business itself.

  
  

  Disadvantages:

  
  

• High cost

  Private cloud models are generally more expensive due to hardware expenses such as servers, network infrastructures, data centers, and software licenses. You need a skilled person to maintain the infrastructure

• High Maintenance Set up and maintenance costs are generally higher. A Private cloud not only needs an investment in hardware, but it also requires continuous maintenance which can be time-consuming.

• Limited remote access Due to increased security in the Private cloud remote access becomes limited. Mobile users in the Private cloud will not be able to connect to the needed business functions whenever they want.

  
  

Community Cloud

Advantages:

• Cost-effective

  A community cloud is cost-effective because the whole cloud is shared between several organizations or a community.

• Improved security, privacy, and reliability Community cloud is more secure than the public cloud but less secure than the private cloud.

• Ease of data sharing and collaboration Community cloud allows us to share cloud resources, infrastructure, and other capabilities among various organizations.

  
  

  Disadvantages:

  
  

• Costs more than a public deployment model Community Cloud is costly than the public cloud.

• Not commonly used Community cloud is not commonly used as of yet.

• Shared storage and bandwidth The fixed amount of data storage and bandwidth is shared among all community members.

  
  

Hybrid Cloud

Advantages:

• Reliability

  Hybrid cloud services offer greater reliability since it reduces potential downtimes. This means that in case of any failure or disaster, the businesses can continue their operations with minimum interruptions.

• Enhanced scalability and flexibility Hybrid cloud is known for its adaption to the organization’s needs. Businesses can scale their resources up and down accordingly. Due to this, they can take advantage of unlimited resources.

• Agility The customization ability of a Hybrid cloud makes sure that the company is agile and cal fulfills the needs of clients.

  
  

  Disadvantages:

  
  

• Security concerns Because of the nature of the Hybrid cloud, there are many security vulnerabilities. Therefore, ensuring adequate security is a difficult process. The responsibility of securing the data completely lies upon the users.

• Maintaining visibility is complicated When running important IT workloads in a hybrid cloud deployment it can be difficult to maintain visibility over everything that you are managing.

• Complex to manage Since it includes multiple types of cloud deployment models you need to have sound experience in managing the system. Hybrid cloud also tends to be very complex and difficult to manage.
