Cost Large upfront cost to implement the hardware, software and staff resources. Maintenance and growth must also be built into ongoing costs. CapEx. Affordable option offering a pay as you go service fee. OpEx – Pay as you go, scale up, scale down as needed, charged by the minute. Security Isolated network environment. Enhanced security to meet data protection legislation. Basic security compliance. Some may offer bolt-on security options. Performance High performance from dedicated server. Competing users can reduce performance levels.

Hi Dipa, Below are some examples of where these are implemented. I hope this might create an understanding of the basic difference between them. The public cloud is where the cloud resources, like servers and storage, are owned and operated by a third-party cloud service provider and delivered over the internet, like for e.g. Microsoft Azure. As it is owned by a third-party, with the public cloud, you share the storage, hardware and network devices with other companies that are subscribed to the same cloud service provider. Public cloud is best suited for – Data storage and archival Application hosting and on-demand hosting for microsite and application Latency intolerant or mission-critical web tiers An auto-scaling environment for large applications. Companies that need an infrastructure to support a large number of customers Those working on projects that encompass many separate entities, like for e.g. research institutions, NGOs. Meanwhile, the private cloud is an infrastructure that is used exclusively by a single organization. It can be physically located at a company’s on-site datacentre or hosted by a third-party provider. In a private cloud, however, the infrastructure and services are maintained on a private network; hardware and software are dedicated solely to your company. Private Cloud is best suited for – Companies that require high data privacy, security, latency and are highly regulated and need advanced private and secure data hosting Companies that need high-performance access to file-system Those that can support the expenditure associated with running next-gen cloud data-center Hosting business-critical data and applications Organizations that need advanced configurability, adaptability, and flexibility

Public Clouds are the most common way of deploying cloud computing. Its storage and servers are owned by a third-party cloud service provider and delivered over the internet. In this, you share the hardware, storage and network devices with other organizations via the internet. In this, you can access your services using a web browser. Microsoft Azure is an example of a Public Cloud. In a Private Cloud, the services and infrastructure are always maintained on a private network and the resources are dedicated solely to your organizations. Private Clouds are often used by one business or organization and also by government agencies. This type of cloud is more scalable and highly protected behind a firewall.

A private cloud solution will host your data on a dedicated server with access and management limited to your business only. The network is protected by a secure firewall and offers high performance due to its single usage. A public cloud solution stores your information off-site on a shared server managed and maintained by the service provider.

Private Cloud: A private cloud solution will host your data on a dedicated server with access and management limited to your business only. The network is protected by a secure firewall and offers high performance due to its single usage. Customers can customise the control and maintenance of their service. This means you can tailor your infrastructure to meet your business needs and to suit any security or infrastructure requirements you have. Public Cloud A public cloud solution stores your information off-site on a shared server managed and maintained by the service provider. Support and updates are handled by the Cloud Service Provider and services are paid for on a subscription basis, reducing the need to invest large amounts of capital and freeing up your in-house IT resources. This gives your business flexibility and allows for quick access to applications and data when testing or as part of a recovery plan. However, it does mean that you have limited control around when and what updates are performed on the system. I hope this is helpful! Ben Martin
