Cloud computing provides organizations with on-demand access to computing resources such as applications, infrastructure, and data storage over the Internet. It allows businesses to access and manage these resources without necessarily maintaining all of the underlying infrastructure themselves.
As cloud computing has evolved, organizations have had to consider factors such as security, privacy, performance, scalability, cost, and control when deciding how to deploy their resources. This has led to three primary cloud models: Public, Private, and Hybrid. Each offers different advantages, allowing organizations to choose the model that best suits their business and IT requirements.
Public Cloud
This is one of the most popular models of Cloud computing that many small and medium enterprises choose to go with. This model works out in terms of services being offered as well as the cost at which they come. Free services are being offered in this model as well, and many individuals choose to opt for it. At the simplest level, people choosing to store their data on Google Drive, Dropbox, etc. is the best example. These services can also support collaboration and sharing, making data easily accessible to authorized users.
The top Public Cloud providers include Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), IBM, Oracle, Salesforce, and others. These providers offer a combination of services ranging from free, subscription-based, usage-based, freemium, premium, and so on. The services provided under these models cover email, applications, storage, development/OS/infrastructure environments, etc.
In this model, the service provider maintains a pool of Cloud computing resources that are shared across customers who opt for the services. This model provides access to instant scalability that suits dynamic business enterprises. Owing to the reduced need for organizations to maintain their own infrastructure and the wide range of services provided, this model happens to be widely adopted.
The Advantages
The advantages of Public Cloud are as follows:
- Low investment in IT infrastructure and maintenance of the same.
- Flexibility to manage dynamic workloads by scaling up or down based on business needs.
- Agility through constant accessibility across the globe for distributed workforces.
- Reliability because of redundancy and availability capabilities offered by many cloud providers.
- Public Cloud providers typically offer extensive security capabilities, but organizations are still responsible for configuring services appropriately and ensuring they meet applicable security and compliance requirements.
Suitability
Public Cloud can suit organizations that prioritize scalability, accessibility, rapid deployment, and reduced infrastructure management. However, organizations handling sensitive or regulated data should evaluate factors such as security controls, compliance requirements, data residency, identity and access management, and the level of control required over their infrastructure and data. In some cases, a Private or Hybrid Cloud may be more appropriate for particular workloads.
They are also well suited to common business services like mail, storage, collaboration, CMS, CRM, and so on. Also, for predictable communication needs, they can support apps and services for everyday business operations. They can also be suitable for running software development and test environments.
Private Cloud
The safety and security concerns of the Public Cloud, especially for enterprises dealing with sensitive information, contributed to the adoption of Private Cloud. As the name suggests, the Cloud here is dedicated to one organization, and hence is private. Though the term private suggests exclusive access to one organization, it need not necessarily be physically present within the premises of the organization. A Private Cloud can be hosted by a cloud service provider, but the infrastructure and Cloud computing resources are dedicated to that organization, providing greater control over security, configuration, and data.
Large companies with specific IT needs usually opt for Private Clouds so that they can customize the Cloud access and storage as per their needs. They will have control over compliance measures to be put in place and complex business requirements can be met. It offers greater visibility but will come with the onus of maintaining safety and security and at a cost. The total cost of ownership will depend on the deployment model, infrastructure, and management requirements.
The Advantages
The advantages of Private Cloud are as follows:
- It gives you more flexibility for customizing the Cloud environment as per your business needs and complexities.
- Dedicated and highly secure environments, with no resources shared with any entity outside the organization other than on a need basis.
- Offers high scalability without giving up direct control over security and infrastructure.
- Compliance and governance controls can be configured to support specific business and regulatory requirements.
- Can be set up to meet high SLAs and performance parameters as required.
Suitability
A Private Cloud is particularly relevant to highly regulated industries and government agencies where the information dealt with is highly sensitive. Organizations that are dependent on the high performance of apps and need strong control over the security and infrastructure may benefit from a Private Cloud. Large technology companies that deal with mission-critical and confidential information may also choose to have a Private Cloud. The efficiency of applications with high performance is another parameter that prompts organizations to go with Private Cloud. Organizations should weigh these benefits against infrastructure, administration, security, and maintenance requirements when evaluating a Private Cloud deployment.
Hybrid Cloud
Interestingly, the needs of many enterprises fall in between the Public and the Private Clouds. They seek to have the best of both worlds, and thus came the concept of a Hybrid Cloud. A Hybrid Cloud comes with great flexibility to move between the Public and the Private Cloud, based on the dynamic business needs. The apps and data in a Hybrid Cloud are maintained within an integrated environment that is designed and arrived at based on various factors like privacy, security, scalability, performance, cost, and at times, a few others.
Workloads can be distributed between Public and Private Cloud environments based on requirements such as security, compliance, performance, scalability, and cost. A ‘Cloud Burst’ happens when there is a sudden huge spike in any of these apps that necessitate the need for extra resources. This is where the flexibility comes in, for moving to the Public Cloud for the extra resources in the on-demand mode only for that short duration. The whole environment is designed for optimum performance and efficiency with the required amounts of scalability. The total cost of a Hybrid Cloud depends on the infrastructure, services, and management requirements involved.
The Advantages
The advantages of a Hybrid Cloud are as follows:
- A high amount of flexibility to scale and distribute workloads between the Private and the Public Cloud based on business and security requirements.
- A high amount of reliability, as the services can be distributed across multiple data centers or environments.
- A greater amount of control over the data, apps, and the environment as dictated by sensitive organizational needs.
- Greater flexibility in how workloads and resources are allocated between Public and Private Cloud environments.
- A phased Cloud migration approach can be taken to ensure gradual workload shifting without affecting any business operations.
Suitability
A Hybrid Cloud is most suited for organizations that have significantly varying workloads, with a combination of security and privacy; precisely the best of both worlds scenario, that they wanted. Organizations that have multiple verticals wherein a few verticals need stringent regulatory compliances, while a few others may not, can opt for this. Organizations providing SaaS may also benefit from additional security, performance, and more by choosing to go with a Hybrid Cloud. Hybrid Clouds can complicate the Cloud environment and security needs, and this needs to be understood and addressed thoroughly before it can be implemented.
