IT solutions in the cloud are now a reality in the global market as cloud computing has helped companies leverage business and attract new opportunities. The trend is that the cloud market will increase even more as companies seek to gain more efficiency and make use of available resources to provide the best service to clients. According to Forrest Research, an American technology research company of global IT, 38% of over 1000 American and European decision-makers of IT infrastructure interviewed said that they are building private cloud environments, 32% are acquiring public cloud services, and the rest intends to implement any form of cloud technology in the next 12 months. Apart from that, 59% of the people questioned said they are implementing hybrid cloud models. (empresa americana de pesquisa de tecnologia na área de TI mundial), 38% dos mais de 1000 decisores norte-americanos e europeus de infraestrutura de TI informaram que estão construindo nuvens privadas, com 32% adquirindo serviços de nuvem pública e o restante planejando implementar alguma forma de tecnologia na nuvem nos próximos 12 meses. Além disso, 59% dos entrevistados informaram que estavam adotando um modelo de nuvem híbrida.
Types of cloud environmentsWhat are private, public, and hybrid clouds? The answer is very simple and will impact directly your business. The private cloud is essentially an environment built in the company’s datacenter, with physic servers, data links, and other necessary components. This cloud also uses the company’s network to provide connection to external users with its own local resources. Therefore, by using a private cloud your company will need to have a few crucial components such as servers where the applications are hosted in the DMZ network. These components will bridge between external users and local resources provided in the company’s datacenter. The public cloud is an environment made available through a network open for public use and the resources are not provided directly by the company’s data center but by another one spread around the world through the WAN network. It has open access and can be used through the internet (WAN), nonetheless credentials are required so that the external connection can happen. Amazon Web Services is one of the drivers in this business branch, created in 2016 and currently moving over $11 billion. The hybrid cloud is a blend of the public and private cloud, so the company provides resources to external users coming from its own datacenter (DMZ network) and third-party datacenters.
The market of cloud solutionsCloud solutions (public, private and hybrid) are popular not only in the US and Europe, but also have grown in Brazil, and the main reasons for that are:
- Facility and simplicity for end-users to access applications without needing technical interventions.
- Accessibility. Data can be reached anywhere in the world, only requiring internet connection without being restricted to local environments and dependent on synchronization of removable media.
- Lower costs. It reduces the need for maintenance of the physical infrastructure of networks client/server, as well as the installation of software in computers. In the cloud, these tasks are attributed to the provider of the software, requiring only that clients have a computer connected to the internet. There is also lowering of costs in reduction of energy consumption, cooling and physical space, which contributes to preservation and rationed use of natural resources.
- Acquisition and usage model. The company won’t need to invest in software perpetual licenses which makes it more expensive along with maintenance expenses. Bearing in mind that the IT area is constantly changing, there will still be a real possibility that in less than a 5 years’ time, the purchased software will not meet the company’s expectations and needs, implying the purchase new software in the future, with the obsoletion of the previous acquisition.
