Cloud Deployment Models. Basics You Should Know

4 Best Cloud Deployment Models

As you should have already noticed, there isn’t just one model that will solve all your problems. There are four different options that must be considered:

  1. Public cloud
  2. Private cloud
  3. Community cloud
  4. Hybrid cloud

We shall cover each below.

1. Public cloud

Just as it is stated in the name, a public cloud can be accessed by all the users. The data in these is created and stored on third-party servers. Whether it is good or not is only determined by the industry and product you’re working with.

Generally, the main advantage is that your company does not have to buy any server infrastructure. This part is covered by the service provider, meaning that they completely maintain their hardware.

Pricing models vary with each provider. Some might charge a fixed price per month with several limitations, others could require payment per each milestone. These details must not be neglected if you want to get the most cost-efficient option.

Pros

  • Third-party provider managed and maintained infrastructure
  • Increased scalability, meaning that you can easily change the cloud’s capacity
  • No need to spend money on infrastructure and software
  • 24/7 availability.

Cons

  • Issues with security and privacy
  • Not good enough for complex solutions
  • Possibility of storage collapse, although the chance is very small.

2. Private cloud

Speaking of private clouds, this choice is completely identical to public ones from a technical point of view. However, they are not available to all users and require authorized access, meaning that this is a better option if you care about privacy.

Different infrastructure models are available. The servers can be hosted externally or within the company, but the location doesn’t matter that much. Everything runs on a private network that is only available to specific users.

Compared to public services, private clouds usually have fewer breaches and work much better in terms of security. It also gives your company direct control over where sensitive data is stored, meaning you can add some new protection layers.

Pros

  • Flexibility
  • Scalability and better customization
  • Better security
  • Reliability.

Cons

  • Higher costs.

3. Community cloud

Imagine an improved version of the private cloud with a possibility to share the data with a broader audience or even with a number of organizations. A community cloud keeps all the security benefits and provides some advantages like easier project creation, management, etc.

Pros

  • Reduced costs in comparison with a private cloud
  • Enhanced security and privacy
  • Facilitated data sharing.

Cons

  • Increased costs in comparison with a public cloud
  • Limited storage
  • Not a very common model.

4. Hybrid cloud

This option gets all the advantages from public, private, and community clouds. Companies can mix different features to get the most suitable combination for their businesses. At the same time, this may mean that part of the infrastructure is outsourced and part is in-house.

Pros

  • Great security features
  • Huge scalability
  • Reasonable pricing
  • Possibility to create a suitable product for any business.

Cons

  • Only works when data is separated properly into sensitive and non-sensitive.

Cloud Deployment Models. Basics You Should Know

What are the best cloud providers?

While choosing the proper cloud model is important, another detail that cannot be neglected is the provider. Making the right choice ensures that the service is used to the fullest extent and you really get all the features that were mentioned.

The 5 best cloud providers are:

  1. Microsoft Azure
  2. Amazon Web Services
  3. Google Cloud
  4. IBM Cloud
  5. Oracle Cloud.

We have covered most of these in our previous articles, so you can check them out in the GlobalCloudTeam’s blog. There also are many other interesting topics that you might want to read about.

What should I choose?

If your business does not worry about security and privacy, does not have huge budgets, and is a small company, then a public cloud would be a good choice.

For sensitive data, like customers’ information or financial transactions, it is better to use a private or hybrid cloud. The latter can also be tweaked in accordance with the needs of your business.

Finally, companies that are working on different projects with various businesses should pay attention to community clouds. This is the best option so far. Moreover, it is quite secure and has many useful features.
