What is Public Cloud ?
In context Public cloud is an IT service which makes all the necessary resources available to the public through the internet.

Let's get started,
Advantages of Public Cloud
1. Scalability
Public cloud services comes with the auto scaling feature. Which means that all the virtual machines present inside the Public cloud system has the capability to get created, scaled, shutdown in an infinite speed. Therefore, ultimately the workload will be balanced according to the needs so that you can avoid downtime and crashes.
2. Cost
Since third party provides the Public cloud services, there is no need for an IT employee to look after and maintain the system. The cost of bandwidth, hardware and application are the sole responsibility of the provider. Hence, the initial investment here is almost zero. Moreover Public cloud services follows the model of pay-as-you-go which means that the payment is made monthly or annually according to the way the resources are being used.
3. Maintenance
All the users of the Public cloud infrastructure are free from the work of maintaining the cloud. The maintenance is solely taken care by the providers. Therefore, the users can focus on other sections of development and testing.
4. Reliability
Public cloud services offer greater reliability. This means there are very less chances of failure interrupting your service. The data center present on the network of servers can undergo frequent failure. Even if it does so, it will not be an issue since the work load will be distributed among the remaining data centers.
5. Data Recovery
A Disaster recovery plan is generally difficult and complex to deploy. That is the reason why most of the IT companies don't consider this implementation. However Public cloud has very little risk of loosing data here. This is because most of the multiple infrastructures available in the Public cloud services.
Disadvantages of Public Cloud
1. Security
The security and privacy of data present inside a Public cloud service remains a concern for many businesses. The Public cloud services offered by many providers are secure to some extent. But the problem lies within the company and how they are going to use them. Therefore, companies must make use of cyber security practices. And also trust in the third party provider is also questioned since they can be from different country having their own set of security and privacy regulations.
2. Flexibility
Even though Public cloud services are very flexible in terms of scalability, there are issues for security and configurations. Some Public cloud providers does not grant freedom to install operating system or switch storage solutions. That is the reason why Public cloud services are not recommended for organizations with compliance regulations.
3. No Control
Using the Public cloud services means that you are sharing the same infrastructure with the other customers. The maintenance and the management has been entirely taken care by the service provider. The users have no control over it.
4. Customization
The atmosphere of the Public cloud service can limit any customization process. Hence, customization of resources or services is almost made impossible in a Public cloud service. This can be disadvantageous especially to the companies with complex network architecture and application process.
5. Customer Support
Public cloud models lacks on the side of customer support. In fact it is a separate contract for the client. Customer support is an important point to remember since some providers does not deliver a quality service. Therefore, users need to discover solutions on their own.
