How to choose cloud computing? Types of cloud computing

The cloud has literally changed the digital world, making it possible for us to use it anywhere and at any time. It’s a great solution if we think not only about simplicity, but and automation and scalability of operations. According to a study IDC Cloud View of 2017, more than half of 11,350 companies will move their entire IT infrastructure to the cloud. How do you choose the type of cloud for your own services?

Cloud computing enables the delivery of computing services, i.e. servers, storage, databases, networks, software, analytics and intelligence via Internet. This saves costs, gains functionality or the ability to scale services. The choice of cloud type depends on the location of IT resources and the model of services provided in the cloud.

Types of cloud computing

1. Public cloud – publicly available, the service belongs to an external
   provider that operates it and provides resources,
   such as servers and storage, via the Internet. The provider manages the hardware, software and
   other supporting infrastructure, and the user has access to the service and
   the ability to manage the account via a web browser. The customer pays
   only for access to the cloud, i.e. for the use of the cloud itself, he does not pay a subscription.
   This is the most convenient, simplest (available immediately) and cheapest solution. It is used
   by many SMEs. It will work well for companies that have
   applications used by a large number of clients, such as e-commerce,
   advertising agencies, social media sites, development companies, report sharing
   public research companies or NGOs. An example
   of a public cloud is Amazon.
2. Private cloud (private cloud) – dedicated hardware resources for the customer. The
   private cloud including the data center, belongs to a specific company or institution.
   The owner controls the correct operation of the private cloud. The user must
   build his own server room, which involves higher costs, but also
   higher level of data security. Private cloud is distinguished from hosting by its scalability,
   i.e. the provider provides administration of virtual machines to
   match the customer’s demand. It can be used by specific
   users, such as company employees. This type of cloud makes sense for
   operations in an industry that imposes a high level of security and confidentiality of
   collected data (legal requirements). The solution is more applicable to large corporations and large
   enterprises.
3. Hybrid cloud (hybrid cloud) – is a combination of public and private
   IT infrastructure to choose the most favorable solution. The customer usually uses
   the computing capabilities of the external cloud, but the data is placed on private
   servers. This type of cloud is chosen by companies that have
   customers with very different needs. It makes it easier to move data, applications or
   services and there is a greater choice of service deployment models.

Cloud service models

Most cloud services fall into several types:

• Colocation, which means renting a server room, accessing power supply, providing air conditioning and Internet access. The customer pays for the hardware, security, load management, operating systems, software and applications. You could say that colocation is a fee for lending space in a server room,
• IaaS (Infrastructure as a Service) – the service provider provides the IT infrastructure, i.e. hardware, software and service and data center space. The user can buy a specific number of servers, disk space or storage and computing power. The customer does not have to invest in hardware, and its services are scalable and flexible. It pays only for the actual consumption of computing power or the rental of disk space.
• PaaS (Platform as a Service) – is a ready-made, customized virtual working environment (platform to work on) for the customer, so he can create his own application in peace. The user does not need to buy hardware or install software. All necessary software, high computing power is provided by the service provider. The customer connects to the service through a browser. It is most often used by IT companies.
• SaaS (Software as a Service) – the goal is to provide the customer with the appropriate off-the-shelf software and IT infrastructure, which runs on the service provider’s servers (externally). The provider manages the infrastructure and takes care of security and software updates. The customer connects to the service via a web browser and pays for SaaS most often on a subscription basis. There are clearly outlined SLA parameters here (a contract containing a guaranteed level of service provision).

• CaaS – Communications as a Service – providing the user with the platform needed to create a telecommunications work environment.

• IpaaS – Integration Platform as a Service –
  aims to enable integration between different services
  provided in the cloud.
