What is Public Cloud? Know Advantages of Public Cloud

Enterprise businesses often look to the public cloud to scale their IT resources as needed without expanding their IT infrastructure. A company may purchase a virtual desktop license instead of buying a desktop machine. Virtual desktops can be activated or spun up in minutes. They can also be found anywhere instantly.

A popular storage solution is a public cloud. Data stored in a public cloud can be accessed from any location and backed up. You can choose from many storage plans. Data that is not needed often can be kept in the public cloud for a very low cost.

A public cloud is a great option for companies hosting applications that are subject to high peak usage.

Let’s dive into the details.

What is Public Cloud?

A public cloud is an IT model. It allows on-demand computing services to be handled by third-party providers and shared with different organizations via the public Internet. The services like software as a Service, Platform as a Service, and Platform as a Service may be offered by public cloud service providers. Users can choose to pay a monthly fee or a per-use fee. This eliminates the need to host these services in their data centers.

Cloud service providers make use of groups of data centers, which are divided into virtual machines that tenants can share. Tenants can rent these virtual machines or pay for additional cloud-based services. The additional cloud-based services incorporate software development tools or storage. Public cloud services are often used by companies to store data that is not frequently accessed or for less-sensitive applications with unpredictable spikes in usage.


A public cloud allows anyone to purchase computing resources. Multiple users usually share a public cloud. On the other hand, a private cloud is a cloud-based service hosted on private servers inside an organization.

How Public Cloud works

The public cloud is a virtualized environment that allows companies to extend their IT infrastructure. It will enable them to host some aspects of their infrastructure on virtual servers that are located off-site and controlled by third parties. There are many strengths to public cloud service providers, including various pricing models and services. If a company considers migrating to the public cloud, it should carefully evaluate its options. This is particularly true if they are getting into a long-term contract. While careful planning can reduce monthly cloud service bills and help you save money, it is difficult for organizations with unpredictable cloud usage to avoid spending large amounts of money when their usage spikes.


IT managers need to consider security in public clouds as servers can share data from multiple companies. Although encryption is a great way to protect data, not all encryption tools work equally well across public and private clouds. Data movement between private data centers or private clouds and public clouds can pose a security risk.


The location of your provider is another consideration, as several countries have data privacy laws that incorporate certain types of data to remain in-country. These laws are constantly changing, so it is a brilliant idea to select a cloud provider that is located in your country. They can also ensure that the servers where your data will be stored comply with local laws for sure. Latency is another issue. If your data is stored on a continent other than your home, it might take longer to transfer it.

Advantages

Get access to new technologies – Organizations that use large cloud providers have instant and early access to the latest IT technologies. These include automatically updated applications, machine learning, and AI. Many cloud customers don’t have the resources or ability to get such access.

Scalability virtually unlimited – Cloud resources and capacity rapidly expand to meet traffic spikes and user demand. The providers have multiple, logically separate cloud locations that offer greater redundancy and availability for public cloud users. Public cloud users have faster connectivity to cloud services and end-users through their provider’s network interfaces.

Flexibility – Public cloud storage is flexible and scalable, allowing users to store large amounts of data and have easy access. There are many companies that rely on the cloud to provide disaster recovery and backup data. Although it is tempting to keep all your data forever, users should establish a data retention policy to ensure that old data is regularly deleted from storage. This will avoid expensive long-term storage and protect privacy.

Analytics –Organizations need to collect valuable metrics about the data and resources they use. Cloud data analytics is another benefit. Cloud services are able to perform high-volume analytics and provide a wide range of data types for business insights.

Disadvantages

Uncontrollable costs – Complex cloud pricing and expenses make it hard for organizations to track IT spending. Although cloud services are often less expensive than those on-premises, some organizations end up spending more. Cloud budgets can be challenging to keep on track due to high data egress fees.

Scarce cloud expertise – The skills gap in the cloud computing industry is another challenge. It is difficult for companies to find and keep staff who has skills in managing cloud applications. Organizations without this knowledge are not trained to deal with modern IT challenges. These IT professionals can prepare better for their careers by improving their cloud skills in architecture, operations, and coding.

Limited control – Public cloud users have to accept that they have limited control over their IT stack, as the provider has the ability to decide when and how configurations should be managed. Public cloud problems include data separation issues due to multi-tenancy and latency issues for remote users.
