Much has been said about cloud computing and how important it is to structuring business on the web. But what most people do not know is that this technology splits into three basic models: public cloud, private cloud, and hybrid cloud. Each has specific characteristics and should be treated separately.
Today, we’ll talk about the public cloud and the post will clarify important questions about how it works, what applications are most appropriate, what its advantages are, and of course the care you need to take when you use it. Are you interested? Keep reading!
What is the public cloud?
A public cloud is based on the standard cloud computing model, in which a provider provides resources and tools, such as applications, data storage spaces, and hosting sites and systems, to the general public.
The public cloud is widely used by individuals as it does not require a larger, more secure infrastructure like those offered in a private cloud model.
However, the public cloud is already used by many companies to make operations significantly more efficient, storing nonsensical content, sharing documents online, and concentrating on certain tasks on it.
How does public cloud work?
The public cloud provides services to multiple clients using the same shared infrastructure. It is a fully virtualized environment with a multi-tenancy architecture (multi-tenant), allowing users to share space, resources, and tools. However, each user’s data and systems remain isolated from each other and there is no interference between them.
While security concerns are often discussed about public cloud environments, when implemented correctly, it can be as secure as implementing a private cloud.
What are the advantages of the public cloud?
Currently, there are companies, especially the smaller ones, that work with an infrastructure totally mounted on public clouds. But as each company has its own particularities, this will depend on the needs and the type of business. So, here are some key benefits of using the public cloud:
Adds business mobility
If your business does not yet have mobility, the public cloud is a good start to implementing the strategy. With it, sharing less sensitive data and less complex tasks such as viewing and analyzing reports can be done using mobile devices from a distance.
This can be advantageous for managers and employees as they will have the flexibility of location and schedules to work. That is: the work can be expanded beyond the walls of the company. This can save a lot of time and costs with locomotion and increase productivity.
Facilitates the creation of a business continuity plan
The public cloud relies on a network of servers to create a redundant system. It is ideal for contributing to a business continuity plan and is mainly used for the execution of automated backups and storage of copies.
If a server fails or needs to be stopped for maintenance and upgrades, helper servers will take action ensuring continuous access to stored data and files.
Are economically viable
One of the key benefits that public cloud delivery is the ease of scalability. Resources are virtually on demand so that any changes in the levels of needs are met easily and without bureaucracy. This, in turn, generates a good value for money.
Because of the pooling of a large amount of resources, users can benefit from economies of scale. This is because centralized operations and resource management are shared at all levels, requiring less investment on proprietary servers.
Public cloud services also use a per-use charging model. So you can access the features and tools you need when you need them and pay only for what you use.
What care should I take when using the public cloud?
Adopt own security policies
Due to the multi-tenancy nature of the public cloud, security is a constant concern for most companies that use it. Even offering technologies such as encryption of passwords and data and access management and user identification tools, managers need to take their own measures to hinder unauthorized access, loss, and theft of information.
Some measures can be:
- Scheduled backups scheduled to run automatically in the cloud;
- not use an open internet network to access the cloud;
- to make users aware of the importance of creating highly secure access passwords and keeping them confidential.
Pay only for your data consumption
Because public cloud services are typically hired in a self-service model, some companies may have trouble tracking precisely what services they use and what they pay. This can generate costs with resources and tools that the company does not even need.
Avoid this by understanding better the packages offered by the provider and migrating the plan to the one that best fits the needs of the business. An IT consulting firm, in this case, can help optimize your cloud investments by identifying and suggesting the ideal cloud consumption scenario for your business.
Make good management
The ideal is to establish a cloud management standard, especially if you use multi-clouds, and include private cloud services in the package. Choose a team of professionals to do this, create methodologies and adopt technologies to better manage clouds and not lose control over them.
Cloud management consulting and outsourcing can be a more effective solution here.
Example of public cloud and the future
The public cloud market has some well-known providers, but Bravens Inc has been notable for the high levels of reliability it has achieved, as well as the resources and management services it provides to users.
Regarding the future, public cloud usage estimates vary widely across countries, but it is expected that the adoption of this tool will increase in the coming years, mainly because of the advantages it offers to businesses.
Following the evolution of Internet technologies, the next generation of public cloud must deliver higher standards of security and rely on improved artificial intelligence capabilities, and further simplify the processes of implementation and business management. This should broaden your participation in the corporate environment.
