It hasn't been many years since the general public heard about the cloud, but the truth is that this technology is the result of a development process that has taken over twenty years.  However, this has been the last 10 times the IT industry has opted for this.

Cloud computing is and will continue to be an integral part of the IT infrastructure, a method that replaces on-premises machines and private data centers with a virtualized infrastructure that provides Internet access to available virtual storage, networking and computing resources.

Therefore, if you want to put such technologies into practice, you can always turn to cloud consulting solutions.

Migrating to the cloud may seem like a complex process, but the truth is that with the right planning, the transition to the cloud can be done gradually and in stages.  If we also prepare a good contingency plan with the scenarios or disruptions we may encounter throughout the process, we will further mitigate the risks of the migration.

But before worrying about migration, it's important to understand what types of cloud computing exist and which ones to consider depending on your company's characteristics and your IT needs.

PUBLIC CLOUD

The most important characteristic of a public cloud is that resources such as servers, storage, and network, i.e. hardware and software, are owned by a third party provider of these services.  It is he who manages them and is responsible for their maintenance and safety.

If the service is purchased by several companies, then the public resources of the cloud are distributed among them. Multiple tenants means multiple access points, so this type of cloud faces a lot of security risks.  While the service is highly reliable in terms of failures and downtime, with an extensive network of servers, security can be more compromised than in a private or hybrid cloud due to its shared architecture.

One of the main advantages of this type of cloud computing is that the payment for the service will depend on your needs.  As such, it is highly scalable and flexible, allowing you to always contract for the level of service that suits you best.  This may be suitable for companies whose workloads are of variable volume or fluctuate over time.

PRIVATE CLOUD

In a private cloud, any resources are available only to your company. Of course, the hardware and software will always be available only to your company.

This type of cloud can be managed by cloud service providers in cases where there are not qualified or sufficient staff to do so.  The strength of this type of computing cloud is that it allows for a higher level of customization to suit specific requirements and needs.

With regard to security, this is entirely up to the organization and, therefore, it will be the organization that will bear the costs associated with its management.  It provides greater risk control and established security mechanisms, making it suitable for those organizations whose business activities involve a high level of confidentiality.

HYBRID CLOUD

A hybrid cloud combines two previous clouds, the resources of which are used according to specific business needs or a specific moment.  Therefore, they can be found both on-premises and in third-party architectures.  This differential characteristic provides organizations with greater flexibility as they can run applications or resources in one or the other, depending on their specific needs.

If we talk about public cloud technologies, then they can be used when the resources of a private cloud are not enough. Cost control is possible because it's pay-as-you-go, so you only pay for extra computing power when you need it.

What to choose is only your decision.
