An automatic prediction suite for cloud resource provisioning

There are mainly two types of clouds - public cloud (provision of cloud services and resources to a large number of clients using publicly accessible large data centers) and private cloud (the organization’s own cloud infrastructure). The public cloud allows you to translate all relevant costs into operating costs and provides a quick and inexpensive launch of an IT solution provided by a Managed Network Services Provider. In the case of a private cloud, capital and investments are preserved - but there is also full control of the IT infrastructure.

However, the famous Oracle approach is based on the concept of a hybrid cloud - the union of private and public clouds, which implements a cross-controlled use of data and applications between them. Oracle implements the cloud bursting concept in a hybrid cloud - the ability to prevent the consequences of overspending on the capacity of a private cloud at peak load through the use of a public cloud. Hybrid cloud is very convenient for development and testing, integration of B2B solutions, implementation of products demanding IT resources, trial operation of new systems.

It is important to remind once again that the cloud is not just a certain number of files on a certain server. A cloud is a cloud when the provision of services, their administration, and payment are automated. That's why we say that a private cloud is the automation, deployment, and management of IT systems managed by Network Security Services. Companies with a large and complex IT infrastructure understand this especially well because it is impossible to manage such infrastructures without automation — which is why the private cloud is especially important for such companies.
Who needs it?
Developers — they can deploy development environments quickly and without bureaucracy.
Testers - they can quickly clone large databases.
Oracle administrators - they can spend less time doing routine tasks.
Financial directors - thanks to the pay-as-you-go system, they have a transparent picture of IT costs.
CEOs of companies that receive flexible IT infrastructure that is easily adaptable to change.
Units that constantly need massive deployment of jobs - for example, training centers (each new student gets a virtual machine).
Good candidates for using DBaaS are companies that:
- use many databases and can take advantage of consolidation
- database cloning is performed regularly
- need detailed monitoring of the use of IT resources by consumers
- have problems at peak times and need the option to increase computational power for such situations
- they want to simplify the administration of IT infrastructure, standardize it, transfer costs from maintaining the infrastructure to its development
- want to provide a high level of reliability and security of applications, but do not have sufficiently experienced database administrators in the state
- do not want to have a large IT department
- they want to increase the efficiency of using a large fleet of equipment
- IT & Managed Security Services providers whose customers are interested in hosting databases, application servers, and virtualization
- use IT hosting;
- provide cloud services like telecom providers.

Criteria of choice
The last few years, debates around cloud technologies on the market have not subsided; what exactly are the advantages of cloud computing for business? And if you still make a choice in favor of cloud-based network security services, then which model in each particular case is the best- a private cloud, a public cloud (public cloud) or a hybrid cloud (hybrid cloud)? The disputes around this issue sometimes remind of political ones: the arguments for and against are in favor of all models, and they are sometimes defended with serious obstinacy. The truth, as usual, is in the middle: in each case, the choice in favor of the presence or absence of a cloud, as well as infrastructure modifications, should be determined by considering the totality of factors.

This article first discusses the differences between the two conceptually opposed models - the private and public clouds. Since hybrid environments are a compromise between these two models and the variations of such hybridization are vast, it will simply make no sense to dwell on the pros and cons of the hybrid cloud.
Public cloud
In the public cloud, Outsourced IT Support Nottingham and infrastructure resources are provided on top of the global Internet. The ability to use the infrastructure of a third-party provider creates many opportunities for the efficient loading of resources and their redistribution. The big factor is that public clouds are much more vulnerable than private ones. However, there are many more advantages for selecting public cloud.
Private cloud
In the private cloud, services and infrastructure resources are interconnected on the basis of the same private network. This model guarantees a significantly higher level of security and control, but the cost of software and hardware when using this approach is significant compared to public clouds. Like the Public cloud, it has also both merits and demerits regarding the selection process.
