In cloud computing resources are provided over a network by sharing a pool of physical or virtual resources. Cloud computing services are offered by cloud providers to a growing number of businesses and they vary depending on the kind of data the customer needs. These clouds can be specified as public, private and hybrid.
Public cloud is the model where services and infrastructure are provided in a virtualized environment available at a public network such as the Internet. Public clouds are very useful for shared resources when the applications are used by a great number of users, when the incremental capacity is required, also in cases of collaboration projects… The only concern about this type of cloud is its security and reliability.
Private cloud is the form where cloud services and infrastructure are provided over a virtual private network. This type is very convenient in cases where privacy issues and security of data and applications are of greatest importance because it offers high-level security and control. The distinction between public and private clouds is not always clear due to the fact that public cloud companies can provide the customer with a private version of their clouds and private cloud providers can offer public versions of their private clouds.
Hybrid cloud is the environment that combines resources some of which are managed in house and externally. Multiple providers communicate with each other to maintain the most efficient environment but this can also pose a problem since the customer must keep track of all different security platforms. This cloud is very convenient in cases when a customer wants to use a SaaS application but worries about security. The additional security is then provided by virtual private network inside the vendor’s firewall.
According to the technology model of the cloud service, 3 most widely spread types include:
Infrastructure as a Service (IaaS) – These providers (most typically Amazon Web Services (AWS), Microsoft Azure and Google Compute Engine) offer storage and virtual servers that can be configured according to your current needs, size of your company, number of users, etc.
Platform as a Service (PaaS) – Most popular with developers, PaaS offers an easily managed system of databases, servers, and management/software development tools.
Software as a Service (SaaS) – This model offers IT companies user-friendly business services and comprehensive business solutions for their everyday needs like CRM and HR.
There’s also a dynamic hybrid cloud that leverages existing public and private cloud solutions in a nonintrusive environment that can run anywhere. It offers the possibility to manage sudden changes, such as adding new resources to the cloud and virtual environment in the fastest possible way.

If the company needs to decide which cloud is right for them, they need to define which level of infrastructure and security is required, as well as what type of management and efficiency of operation is expected.
Choosing the right cloud provider is very important. Apart from the price check the other things like references, 24/7 support, support delivery method… Many of our clients are cloud providers which recognized the importance of excellent End-user and infrastructure support which are part of SuperAdmins standard offer.
