Public Cloud

    Run anywhere and scale globally in the public cloud of your choice

    Public clouds are the most common type of cloud computing deployment. The cloud resources (like servers and storage) are owned and operated by a third-party cloud service provider and delivered over the internet. With a public cloud, all hardware, software, and other supporting infrastructure are owned and managed by the cloud provider. Microsoft Azure, Google Cloud, AWS are an example of a public cloud.

    In a public cloud, you share the same hardware, storage and network devices with other organisations or cloud “tenants,” and you access services and manage your account using a web browser. Public cloud deployments are frequently used to provide web-based email, online office applications, storage and testing and development environments.

  • Advantages

    • Simple and easy:

      • Public clouds are available as a service in the internet, they are easy to deploy.

    • Lower costs

      • no need to purchase hardware or software and you pay only for the service you use.

    • Less time:

      • The IT resources and services are available immediately saving time for the company.

    • No Maintenance:

      • Easy infrastructure management. As public clouds are managed by a third party, it is an easy, hassle-free system. There is no need for a company to create its own software – the third party takes care of it.

    • Up-time:

      • Expect to be running 24/7. Public cloud networks are extensive, meaning there is availability and can rely on improved operation time.

    • Elastic & Scalable:

      • Get high scalability & reliability as you get on-demand resources to meet your business needs.

    • Redundancy:

      • With a vast network of servers to guard against failure.

    • No contracts:

      • No long-term commitment with service provider because public clouds are usually pay-as-you-go models.

  • Disadvantages

    • Lacks proper controls:

      • The client has no control of data or infrastructure. There are issues of data privacy and integrity. The service level policies and compliances are completely enforced by the service provider.

    • Performance:

      • The performance of the network depends on the speed of the internet connectivity.

    • Data security and privacy:

      • When access to data is easy, public clouds don’t allow users to see where the information is being kept and who has access to it.

    • Customization:

      • Customization of resources or services is not possible.
