Now, let’s talk about the two most popular clouds – public cloud and private cloud –
Definition and Brief Information about Public Cloud
The public cloud is a cloud computing model that delivers IT services using the Internet to all its clients. The services are usually based on premium or are free and at times they may be based on subscription-based model on how much volume of all the computing resources is consumed by a client.
Using a public cloud, all types of hardware, software, network devices are owned and handled by the cloud provider. Public cloud services are highly scalable and offer huge elasticity. The vendors of public cloud are the one who is involved in managing and maintaining and the development of the various computing resources that have been shared between various clients.
Top Features of Public Cloud
- Public cloud supports on-demand self-service which is a vital feature of cloud computing.
- Managing servers is not an easy task and using the public cloud, you can decrease the downtime and easily maintain the server.
- You can access data of the cloud and even can upload it to the cloud from anywhere using a device and a strong Internet connection.
- The public cloud offers huge scalability that comprises many resources available to the cloud and users can access them seamlessly using the Internet.
- It is very cost-effective to use the public cloud as they are easily available in the market and businesses can adopt it without much investment.
Beneficial Points of Public Cloud
- Highly cost-effective
The public cloud has a flexible pricing structure and this is considered as it’s one of the top benefits. Whether it is a small, mid-level, or a huge enterprise, all of them can benefit their business using the public cloud. Also, it provides a special benefit of pricing its services at an hourly basis that helps any level of business to benefit from the public cloud.
- Easy to set up
The public cloud can be set up in just a few hours by the IT team. It requires only the internet and then it will be deployed and configured remotely using the cloud providing website.
- It requires no maintenance
Talking about maintaining the public cloud then it is the role of a cloud provider who is responsible for managing and maintaining the hardware, software, and all kinds of networks in the cloud.
- Offers enhanced security
With the evolving technology, companies are looking for more and more security aspects to adopt in their business. The public cloud has all the capability to offer enhanced security as it covers cybersecurity expertise, regular penetration testing, controlled access, and more such security measure that will keep your business safe and secure.
- Saves time and money
Being a public cloud user, the responsibility of managing the cloud hosting solution is taken by the cloud computing service provider. Also, it enables the developer for adopting agile workflow and this saves a lot of lead times that are required for testing and deploying new products. Talking about money, then it requires no capital investments, no maintenance, and update cost, and you can pay-as-you-use it.
Drawbacks of Public Cloud
- Less controlling power
Outsourcing the technology to the public cloud will lose all the control from your hands. All types of configuration aspects that are related to the management of IT as well as physical and cybersecurity will be left to the people of the team who will get removed from performing the daily activities of your business. With the help of external support, it will become possible to manage all the activities.
- Customization option is not available
There is no such way through which you can perform the customization of your resources or services. The public cloud does not provide or support any of the customization features.
- Weak security measures
This is probably the main drawback of the public cloud that it offers weak security while managing the server activities on the cloud. It is always important for customers to keep sensitive information secure.
- Less understanding of the back-end process
When it is about managing the physical security, then the cloud provider is responsible for managing it and enforcing the external firewall policies. The public cloud does not have any knowledge of handling the back-end data and how it will going to process for giving the expected results.
- Less contract support
The public cloud model has a separate contract for support as some of the providers does not offer the best service as per the expectation in an enterprise system.
Applications based on Public Cloud
- Google App Engine
- Azure Services Platform by Windows
- Blue Cloud by IBM
- Amazon Elastic Cloud Compute (EC2)
Understanding Private Cloud
The term Private in Private cloud itself is defining its nature that it will be dedicated to any single organization and will not share cloud computing resources with any other organization. It is a customized cloud to meet the business and security measures of a particular organization. In this, applications are being made available virtually on the cloud and they are not allowed to run on local servers.
Talking about the security measures of the private cloud, there is a firewall that is present to protect the private cloud from any unknown or unauthorized access. Only authorized users have permission to access the private cloud applications via VPN (Virtual Private Networks) or through the intranet of the client’s organization.
Highlighted features of Private Cloud
- Highly scalable and offers different levels of utilization through the size and maturity of data centers.
- Offers high security and privacy measures making it the most secure cloud.
- Private cloud services offer more control as the organization’s needs are restricted to the network solution only.
