What Are the Different Types of Cloud Computing?

Cloud computing is a broad term which includes all the services enabled on the cloud platform and it ultimately increases the IT capacity and functionality. Cloud is the on-demand technology which has really changed the way the business used to work earlier all across different industries. The cloud technologies today have completely transformed the way the organizations used to procure and maintain the infrastructure. Cloud computing nowadays has become very popular and offers different kinds of deployment models as per the requirement of the business. The companies should thus hire aws developers in for easy deployment of the cloud technology in their organization.

Types of Cloud Deployment models:

Now let’s understand about Cloud Deployment. Cloud Deployment basically refers to the way a cloud platform is implemented, how it is hosted and who all have access to the same. Amazon AWS web development services provides details of different cloud deployment services. The cloud deployment services can be divided into four broad categories as mentioned below:

  1. Private Cloud

This kind of cloud deployment model is owned by any single business only and cannot be shared with anyone. It refers to a completely on-premises cloud where it is under strict control of the business itself. This can be managed in two ways- either hosted externally or managed completely in-house.

This can be a costly affair for any company to manage the private cloud as they should then have a dedicated IT team to take care of the issues related to it, huge investment is required to create the well-built infrastructure and then provide it with a layer of tight security as well. Here the companies have to internally handle all the hardware elements.

Advantages:

  1. It is the same as legacy IT infrastructure and supports legacy apps.
  2. High level of tight security and control over the server
  3. Easy restrictions to access the valuable assets of the organization
  4. Not at all affected by the downtime of the public cloud.
  5. Possess high level of flexibility thus changes can be made as per business requirement and that too without compromising with the security, thus highly customizable.
  6. Comparatively, the government and regulatory compliances are easier and simpler.
  7. Improved functionality due to high level of efficiency.

Disadvantages:

  1. Highly expensive
  2. Difficult to access the date from the remote locations
  3. Lacks the versatility of the public clouds
  4. It can only be expanded by adding more of hardware and storage capacity which is quite time-consuming activity
  5. Need experts from the field to master the whole thing
  6. Mobile users have very limited access.

2) Public Cloud

Public cloud refers to such a cloud where the infrastructure is provided by the outside- cloud provider and this cloud is accessible to many businesses over the internet through a pay-per-use model. It is quite economical as the users do not have to pay for the infrastructure of the dedicated IT team, but they only need to pay as per their usage. It is considered an ideal model to follow for the small and medium sized business who aims to get advantage of cloud technology but at a cheaper rate.

Advantages:

  1. Very cost effective
  2. Massive amount of space available to use
  3. The scalability is very easy, there is a provision of increasing the capacity as per the demand of the business.
  4. Completely virtualized infrastructure.
  5. Highly reliable system
  6. Free from all kinds of geographical restrictions

Disadvantages:

  1. Not considered to be very safe for very confidential or sensitive information.
  2. Difficulty in relocating their service-provider with the new one.
  3. Risk of the service-providers leaving the business and making the changes of platform without any prior information.

3) Hybrid Cloud

As the word defines it is a combination of public and private cloud. Here the infrastructure is common but some of the apps or functionalities which are very sensitive are privatized for their security. Here the two platforms interact seamlessly. It aims to provide tailor-made solutions as per the requirement of the business owners.

It can also be called a mid-way to interconnect the cloud-based resources and the existing resources of the companies which are not based on the cloud. It is perfect for those businesses which want to take a bit of advantage of both the platforms.

Advantages:

  1. A perfect combination of scalable and flexible computing ability of the public cloud and security and control of a private cloud.
  2. Quite cost effective
  3. Both Native and legacy -part of the cloud can be utilized.
  4. Government and legal compliances are simpler than the public cloud.
  5. It is an authentic service provider and offers shared services across different cloud platforms.

Disadvantages:

1)As it is used by both private and public clouds, hence communication at the network level can face some conflicts.

2)Huge amounts of unstructured data can give actionable insights.

3)Infrastructure gets complicated due to integration of public and private clouds.

4) Community cloud

It refers to an environment consisting of more than a single public cloud service provider along with a private cloud service provider. It is used by different organizations to share some of the common applications. Typically used by sectors like financial services firms, healthcare service providers, government agencies etc.

Advantages:

  1. Easy scalability and cost of the same can be shared among different organizations.
  2. Decision making regarding any changes in the system is collaborative and is made for interests across all the groups of people.
  3. The individual organizations can set their access control and allow the system to act as per the requirement of their business.

Disadvantages:

  1. Due to shared bandwidth and storages, sometimes the performance of the organization suffers.
  2. Shortage of storage data leads to security concerns.

MULTI-CLOUD MODEL:

When the organization is big and is using the public cloud, it might happen that the single cloud service provider could not accommodate the needs of the organization, so they move to a multi-cloud model. It may refer to a complex form of hybrid cloud which is a combination of one public cloud provider along with multiple private cloud providers.

Here the organizations have access to multiple clouds from the public as well as private service providers, thus companies have choice to pick and choose among many.

Advantages:

1)The organizations with more workloads can use different clouds which ultimately boosts the overall performance.

2)In the long run, it not just decreases the cost but also increases the efficiency and flexibility.

3)Free from the problem of vendor lock-in.

4)The compliance is raised in order to meet the standards of different companies.

5)The productivity is enhanced as now companies are not dependent on a single platform and can easily switch to work on different clouds if one of them is going through downtime.

CONCLUSION:

The technology of cloud computing has completely changed the business used to work earlier.  Different types of clouds provide different benefits, so one can easily select as per the demand of the business, how much the companies can afford, what fits the best as per business requirement. Thus, one should select the correct cloud service provider which can help them to reap the benefits.
